+acpica-unix
+-----------
+
+This source release includes:
+
+
+1) a cross-OS AML interpreter
+
+This is intended to allow commercial and open source operating systems
+to be enabled for ACPI. OS specific code is still needed, but the
+AML interpreter should greatly improve the development speed of ACPI
+support.
+
+The AML interpreter source should be integrated into the kernel's
+build process. We recommend establishing an automated method for
+this, so later versions can also be incorporated easily. Please see
+the documentation on the website for API and other implementation
+information.
+
+
+2) iasl, an ASL compiler/decompiler
+
+iasl compiles ASL (ACPI Source Language) into AML (ACPI Machine
+Language). This AML is suitable for inclusion as a DSDT in system
+firmware. It also can disassemble AML, for debugging purposes.
+
+To compile:
+
+cd compiler
+make
+
+It has been compiled on Linux, but should easily port to other Unix
+environments.
+
+Run 'iasl -h' for more information, or download the binary version for
+documentation in PDF format.
+
+
+3) acpisrc, a source code conversion tool
+
+acpisrc converts the standard form of the acpica source release (included
+here) into a version that meets Linux coding guidelines. This consists
+mainly of performing a series of string replacements and transformations
+to the code.
+
+To compile:
+
+cd tools/acpisrc
+make
+
+It has been compiled on Linux, but should easily port to other Unix
+environments.
+
+
+4) acpibin, an AML file tool
+
+acpibin compares AML files, dumps AML binary files to text files,
+extracts binary AML from text files, and other AML file
+manipulation.
+
+To compile:
+
+cd tools/acpibin
+make
+
+
+5) acpiexec, a user-space AML interpreter
+
+acpiexec allows the loading of ACPI tables and execution of control
+methods from user space.  Useful for debugging AML code and testing
+the AML interpreter.
+
+To compile:
+
+cd tools/acpiexec
+make
+
+

+----------------------------------------
+28 May 2010. Summary of changes for version 20100528:
+
+This release is available at www.acpica.org/downloads
+
+Note: The ACPI 4.0a specification was released on April 5, 2010 and is 
+available at www.acpi.info. This is primarily an errata release.
+
+1) ACPI CA Core Subsystem:
+
+Undefined ACPI tables: We are looking for the definitions for the following 
+ACPI tables that have been seen in the field: ATKG, IEIT, GSCI.
+
+Implemented support to enable multi-byte transfers for Embedded Controller 
+(EC) operation regions. Previously, the maximum data size passed to the EC 
+operation region handler was a single byte. There are often EC Fields larger 
+than one byte that need to be transferred, and it is useful for the EC driver 
+to lock these as a single transaction. This change enables single transfers 
+larger than 8 bits. This effectively changes the access to the EC space from 
+ByteAcc to AnyAcc, and will probably require changes to the host OS Embedded 
+Controller driver to enable 16/32/64/256-bit transfers in addition to 8-bit 
+transfers. Alexey Starikovskiy, Lin Ming
+
+Implemented a performance enhancement for namespace search and access. This 
+change enhances the performance of namespace searches and walks by adding a 
+backpointer to the parent in each namespace node. On large namespaces, this 
+change can improve overall ACPI performance by up to 9X. Adding a pointer to 
+each namespace node increases the overall size of the internal namespace by 
+about 5%, since each namespace entry usually consists of both a namespace 
+node and an ACPI operand object. However, this is the first growth of the 
+namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy.
+
+Implemented a performance optimization that reduces the number of namespace 
+walks. On control method exit, only walk the namespace if the method is known 
+to have created namespace objects outside of its local scope. Previously, the 
+entire namespace was traversed on each control method exit. This change can 
+improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob Moore.
+
+Added support to truncate I/O addresses to 16 bits for Windows compatibility. 
+Some ASL code has been seen in the field that inadvertently has bits set 
+above bit 15. This feature is optional and is enabled if the BIOS requests 
+any Windows OSI strings. It can also be enabled by the host OS. Matthew 
+Garrett, Bob Moore.
+
+Added support to limit the maximum time for the ASL Sleep() operator. To 
+prevent accidental deep sleeps, limit the maximum time that Sleep() will 
+actually sleep. Configurable, the default maximum is two seconds. ACPICA 
+bugzilla 854.
+
+Added run-time validation support for the _WDG and_WED Microsoft predefined 
+methods. These objects are defined by "Windows Instrumentation", and are not 
+part of the ACPI spec. ACPICA BZ 860.
+
+Expanded all statistic counters used during namespace and device 
+initialization from 16 to 32 bits in order to support very large namespaces.
+
+Replaced all instances of %d in printf format specifiers with %u since nearly 
+all integers in ACPICA are unsigned.
+
+Fixed the exception namestring for AE_WAKE_ONLY_GPE. Was incorrectly returned 
+as AE_NO_HANDLER.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  88.4K Code, 18.8K Data, 107.2K Total
+    Debug Version:     164.2K Code, 51.5K Data, 215.7K Total
+  Current Release:
+    Non-Debug Version:  88.3K Code, 18.8K Data, 107.1K Total
+    Debug Version:     164.1K Code, 51.5K Data, 215.6K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Added compiler support for the _WDG and_WED Microsoft predefined 
+methods. These objects are defined by "Windows Instrumentation", and are not 
+part of the ACPI spec. ACPICA BZ 860.
+
+AcpiExec: added option to disable the memory tracking mechanism. The -dt 
+option will disable the tracking mechanism, which improves performance 
+considerably.
+
+AcpiExec: Restructured the command line options into -d (disable) and -e 
+(enable) options.
+
+----------------------------------------
+28 April 2010. Summary of changes for version 20100428:
+
+1) ACPI CA Core Subsystem:
+
+Implemented GPE support for dynamically loaded ACPI tables. For all GPEs, 
+including FADT-based and GPE Block Devices, execute any _PRW methods in the 
+new table, and process any _Lxx/_Exx GPE methods in the new table. Any 
+runtime GPE that is referenced by an _Lxx/_Exx method in the new table is 
+immediately enabled. Handles the FADT-defined GPEs as well as GPE Block 
+Devices. Provides compatibility with other ACPI implementations. Two new 
+files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob Moore.
+
+Fixed a regression introduced in version 20100331 within the table manager 
+where initial table loading could fail. This was introduced in the fix for 
+AcpiReallocateRootTable. Also, renamed some of fields in the table manager 
+data structures to clarify their meaning and use.
+
+Fixed a possible allocation overrun during internal object copy in 
+AcpiUtCopySimpleObject. The original code did not correctly handle the case 
+where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 847.
+
+Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a 
+possible access beyond end-of-allocation. Also, now fully validate descriptor 
+(size and type) before output. Lin Ming, Bob Moore. ACPICA BZ 847
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Implemented Min/Max/Len/Gran validation for address resource 
+descriptors. This change implements validation for the address fields that 
+are common to all address-type resource descriptors. These checks are 
+implemented: Checks for valid Min/Max, length within the Min/Max window, 
+valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as per 
+table 6-40 in the ACPI 4.0a specification. Also split the large aslrestype1.c 
+and aslrestype2.c files into five new files. ACPICA BZ 840.
+
+iASL: Added support for the _Wxx predefined names. This support was missing 
+and these names were not recognized by the compiler as valid predefined 
+names. ACPICA BZ 851.
+
+iASL: Added an error for all predefined names that are defined to return no 
+value and thus must be implemented as Control Methods. These include all of 
+the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous 
+names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856.
+
+iASL: Implemented the -ts option to emit hex AML data in ASL format, as an 
+ASL Buffer. Allows ACPI tables to be easily included within ASL files, to be 
+dynamically loaded via the Load() operator. Also cleaned up output for the -
+ta and -tc options. ACPICA BZ 853.
+
+Tests: Added a new file with examples of extended iASL error checking. 
+Demonstrates the advanced error checking ability of the iASL compiler. 
+Available at tests/misc/badcode.asl.
+
+----------------------------------------
+31 March 2010. Summary of changes for version 20100331:
+
+1) ACPI CA Core Subsystem:
+
+Completed a major update for the GPE support in order to improve support for 
+shared GPEs and to simplify both host OS and ACPICA code. Added a reference 
+count mechanism to support shared GPEs that require multiple device drivers. 
+Several external interfaces have changed. One external interface has been 
+removed. One new external interface was added. Most of the GPE external 
+interfaces now use the GPE spinlock instead of the events mutex (and the 
+Flags parameter for many GPE interfaces has been removed.) See the updated 
+ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, Rafael 
+Wysocki. ACPICA BZ 831.
+
+Changed:
+    AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus
+Removed:
+    AcpiSetGpeType
+New:
+    AcpiSetGpe
+
+Implemented write support for DataTable operation regions. These regions are 
+defined via the DataTableRegion() operator. Previously, only read support was 
+implemented. The ACPI specification allows DataTableRegions to be read/write, 
+however.
+
+Implemented a new subsystem option to force a copy of the DSDT to local 
+memory. Optionally copy the entire DSDT to local memory (instead of simply 
+mapping it.) There are some (albeit very rare) BIOSs that corrupt or replace 
+the original DSDT, creating the need for this option. Default is FALSE, do 
+not copy the DSDT.
+
+Implemented detection of a corrupted or replaced DSDT. This change adds 
+support to detect a DSDT that has been corrupted and/or replaced from outside 
+the OS (by firmware). This is typically catastrophic for the system, but has 
+been seen on some machines. Once this problem has been detected, the DSDT 
+copy option can be enabled via system configuration. Lin Ming, Bob Moore.
+
+Fixed two problems with AcpiReallocateRootTable during the root table copy. 
+When copying the root table to the new allocation, the length used was 
+incorrect. The new size was used instead of the current table size, meaning 
+too much data was copied. Also, the count of available slots for ACPI tables 
+was not set correctly. Alexey Starikovskiy, Bob Moore.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  87.5K Code, 18.4K Data, 105.9K Total
+    Debug Version:     163.4K Code, 51.1K Data, 214.5K Total
+  Current Release:
+    Non-Debug Version:  87.9K Code, 18.6K Data, 106.5K Total
+    Debug Version:     163.5K Code, 51.3K Data, 214.8K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Implement limited typechecking for values returned from predefined 
+control methods. The type of any returned static (unnamed) object is now 
+validated. For example, Return(1). ACPICA BZ 786.
+
+iASL: Fixed a predefined name object verification regression. Fixes a problem 
+introduced in version 20100304. An error is incorrectly generated if a 
+predefined name is declared as a static named object with a value defined 
+using the keywords "Zero", "One", or "Ones". Lin Ming.
+
+iASL: Added Windows 7 support for the -g option (get local ACPI tables) by 
+reducing the requested registry access rights. ACPICA BZ 842.
+
+Disassembler: fixed a possible fault when generating External() statements. 
+Introduced in commit ae7d6fd: Properly handle externals with parent-prefix 
+(carat). Fixes a string length allocation calculation. Lin Ming.
+
+----------------------------------------
+04 March 2010. Summary of changes for version 20100304:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a possible problem with the AML Mutex handling function 
+AcpiExReleaseMutex where the function could fault under the very rare 
+condition when the interpreter has blocked, the interpreter lock is released, 
+the interpreter is then reentered via the same thread, and attempts to 
+acquire an AML mutex that was previously acquired. FreeBSD report 140979. Lin 
+Ming.
+
+Implemented additional configuration support for the AML "Debug Object". 
+Output from the debug object can now be enabled via a global variable, 
+AcpiGbl_EnableAmlDebugObject. This will assist with remote machine debugging. 
+This debug output is now available in the release version of ACPICA instead 
+of just the debug version. Also, the entire debug output module can now be 
+configured out of the ACPICA build if desired. One new file added, 
+executer/exdebug.c. Lin Ming, Bob Moore.
+
+Added header support for the ACPI MCHI table (Management Controller Host 
+Interface Table). This table was added in ACPI 4.0, but the defining document 
+has only recently become available.
+
+Standardized output of integer values for ACPICA warnings/errors. Always use 
+0x prefix for hex output, always use %u for unsigned integer decimal output. 
+Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 400 
+invocations.) These invocations were converted from the original 
+ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  87.1K Code, 18.0K Data, 105.1K Total
+    Debug Version:     163.5K Code, 50.9K Data, 214.4K Total
+  Current Release:
+    Non-Debug Version:  87.5K Code, 18.4K Data, 105.9K Total
+    Debug Version:     163.4K Code, 51.1K Data, 214.5K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Implemented typechecking support for static (non-control method) 
+predefined named objects that are declared with the Name() operator. For 
+example, the type of this object is now validated to be of type Integer: 
+Name(_BBN, 1). This change migrates the compiler to using the core predefined 
+name table instead of maintaining a local version. Added a new file, 
+aslpredef.c. ACPICA BZ 832.
+
+Disassembler: Added support for the ACPI 4.0 MCHI table.
+
+----------------------------------------
+21 January 2010. Summary of changes for version 20100121:
+
+1) ACPI CA Core Subsystem:
+
+Added the 2010 copyright to all module headers and signons. This affects 
+virtually every file in the ACPICA core subsystem, the iASL compiler, the 
+tools/utilities, and the test suites.
+
+Implemented a change to the AcpiGetDevices interface to eliminate unnecessary 
+invocations of the _STA method. In the case where a specific _HID is 
+requested, do not run _STA until a _HID match is found. This eliminates 
+potentially dozens of _STA calls during a search for a particular device/HID, 
+which in turn can improve boot times. ACPICA BZ 828. Lin Ming.
+
+Implemented an additional repair for predefined method return values. Attempt 
+to repair unexpected NULL elements within returned Package objects. Create an 
+Integer of value zero, a NULL String, or a zero-length Buffer as appropriate. 
+ACPICA BZ 818. Lin Ming, Bob Moore.
+
+Removed the obsolete ACPI_INTEGER data type. This type was introduced as the 
+code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with 
+64-bit AML integers). It is now obsolete and this change removes it from the 
+ACPICA code base, replaced by UINT64. The original typedef has been retained 
+for now for compatibility with existing device driver code. ACPICA BZ 824.
+
+Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field in 
+the parse tree object.
+
+Added additional warning options for the gcc-4 generation. Updated the source 
+accordingly. This includes some code restructuring to eliminate unreachable 
+code, elimination of some gotos, elimination of unused return values, some 
+additional casting, and removal of redundant declarations.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  87.0K Code, 18.0K Data, 105.0K Total
+    Debug Version:     163.4K Code, 50.8K Data, 214.2K Total
+  Current Release:
+    Non-Debug Version:  87.1K Code, 18.0K Data, 105.1K Total
+    Debug Version:     163.5K Code, 50.9K Data, 214.4K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+No functional changes for this release.
+
+----------------------------------------
+14 December 2009. Summary of changes for version 20091214:
+
+1) ACPI CA Core Subsystem:
+
+Enhanced automatic data type conversions for predefined name repairs. This 
+change expands the automatic repairs/conversions for predefined name return 
+values to make Integers, Strings, and Buffers fully interchangeable. Also, a 
+Buffer can be converted to a Package of Integers if necessary. The nsrepair.c 
+module was completely restructured. Lin Ming, Bob Moore.
+
+Implemented automatic removal of null package elements during predefined name 
+repairs. This change will automatically remove embedded and trailing NULL 
+package elements from returned package objects that are defined to contain a 
+variable number of sub-packages. The driver is then presented with a package 
+with no null elements to deal with. ACPICA BZ 819.
+
+Implemented a repair for the predefined _FDE and _GTM names. The expected 
+return value for both names is a Buffer of 5 DWORDs. This repair fixes two 
+possible problems (both seen in the field), where a package of integers is 
+returned, or a buffer of BYTEs is returned. With assistance from Jung-uk Kim.
+
+Implemented additional module-level code support. This change will properly 
+execute module-level code that is not at the root of the namespace (under a 
+Device object, etc.). Now executes the code within the current scope instead 
+of the root. ACPICA BZ 762. Lin Ming.
+
+Fixed possible mutex acquisition errors when running _REG methods. Fixes a 
+problem where mutex errors can occur when running a _REG method that is in 
+the same scope as a method-defined operation region or an operation region 
+under a module-level IF block. This type of code is rare, so the problem has 
+not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.
+
+Fixed a possible memory leak during module-level code execution. An object 
+could be leaked for each block of executed module-level code if the 
+interpreter slack mode is enabled This change deletes any implicitly returned 
+object from the module-level code block. Lin Ming.
+
+Removed messages for successful predefined repair(s). The repair mechanism 
+was considered too wordy. Now, messages are only unconditionally emitted if 
+the return object cannot be repaired. Existing messages for successful 
+repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  86.6K Code, 18.2K Data, 104.8K Total
+    Debug Version:     162.7K Code, 50.8K Data, 213.5K Total
+  Current Release:
+    Non-Debug Version:  87.0K Code, 18.0K Data, 105.0K Total
+    Debug Version:     163.4K Code, 50.8K Data, 214.2K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a regression introduced in 20091112 where intermediate .SRC files 
+were no longer automatically removed at the termination of the compile.
+
+acpiexec: Implemented the -f option to specify default region fill value. 
+This option specifies the value used to initialize buffers that simulate 
+operation regions. Default value is zero. Useful for debugging problems that 
+depend on a specific initial value for a region or field.
+
+----------------------------------------
+12 November 2009. Summary of changes for version 20091112:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a post-order callback to AcpiWalkNamespace. The existing 
+interface only has a pre-order callback. This change adds an additional 
+parameter for a post-order callback which will be more useful for bus scans. 
+ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference.
+
+Modified the behavior of the operation region memory mapping cache for 
+SystemMemory. Ensure that the memory mappings created for operation regions 
+do not cross 4K page boundaries. Crossing a page boundary while mapping 
+regions can cause kernel warnings on some hosts if the pages have different 
+attributes. Such regions are probably BIOS bugs, and this is the workaround. 
+Linux BZ 14445. Lin Ming.
+
+Implemented an automatic repair for predefined methods that must return 
+sorted lists. This change will repair (by sorting) packages returned by _ALR, 
+_PSS, and _TSS. Drivers can now assume that the packages are correctly sorted 
+and do not contain NULL package elements. Adds one new file, 
+namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore.
+
+Fixed a possible fault during predefined name validation if a return Package 
+object contains NULL elements. Also adds a warning if a NULL element is 
+followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement may 
+include repair or removal of all such NULL elements where possible.
+
+Implemented additional module-level executable AML code support. This change 
+will execute module-level code that is not at the root of the namespace 
+(under a Device object, etc.) at table load time. Module-level executable AML 
+code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming.
+
+Implemented a new internal function to create Integer objects. This function 
+simplifies miscellaneous object creation code. ACPICA BZ 823.
+
+Reduced the severity of predefined repair messages, Warning to Info. Since 
+the object was successfully repaired, a warning is too severe. Reduced to an 
+info message for now. These messages may eventually be changed to debug-only. 
+ACPICA BZ 812.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  85.8K Code, 18.0K Data, 103.8K Total
+    Debug Version:     161.8K Code, 50.6K Data, 212.4K Total
+  Current Release:
+    Non-Debug Version:  86.6K Code, 18.2K Data, 104.8K Total
+    Debug Version:     162.7K Code, 50.8K Data, 213.5K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Implemented Switch() with While(1) so that Break works correctly. This 
+change correctly implements the Switch operator with a surrounding While(1) 
+so that the Break operator works as expected. ACPICA BZ 461. Lin Ming.
+
+iASL: Added a message if a package initializer list is shorter than package 
+length. Adds a new remark for a Package() declaration if an initializer list 
+exists, but is shorter than the declared length of the package. Although 
+technically legal, this is probably a coding error and it is seen in the 
+field. ACPICA BZ 815. Lin Ming, Bob Moore.
+
+iASL: Fixed a problem where the compiler could fault after the maximum number 
+of errors was reached (200).
+
+acpixtract: Fixed a possible warning for pointer cast if the compiler warning 
+level set very high.
+
+----------------------------------------
+13 October 2009. Summary of changes for version 20091013:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where an Operation Region _REG method could be executed more 
+than once. If a custom address space handler is installed by the host before 
+the "initialize operation regions" phase of the ACPICA initialization, any 
+_REG methods for that address space could be executed twice. This change 
+fixes the problem. ACPICA BZ 427. Lin Ming.
+
+Fixed a possible memory leak for the Scope() ASL operator. When the exact 
+invocation of "Scope(\)" is executed (change scope to root), one internal 
+operand object was leaked. Lin Ming.
+
+Implemented a run-time repair for the _MAT predefined method. If the _MAT 
+return value is defined as a Field object in the AML, and the field
+size is less than or equal to the default width of an integer (32 or 64),_MAT 
+can incorrectly return an Integer instead of a Buffer. ACPICA now 
+automatically repairs this problem. ACPICA BZ 810.
+
+Implemented a run-time repair for the _BIF and _BIX predefined methods. The 
+"OEM Information" field is often incorrectly returned as an Integer with 
+value zero if the field is not supported by the platform. This is due to an 
+ambiguity in the ACPI specification. The field should always be a string. 
+ACPICA now automatically repairs this problem by returning a NULL string 
+within the returned Package. ACPICA BZ 807.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+

+    Debug Version:     161.7K Code, 50.9K Data, 212.6K Total
+  Current Release:

+    Debug Version:     161.8K Code, 50.6K Data, 212.4K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Fixed a problem where references to external symbols that 
+contained one or more parent-prefixes (carats) were not handled correctly, 
+possibly causing a fault. ACPICA BZ 806. Lin Ming.
+
+Disassembler: Restructured the code so that all functions that handle 
+external symbols are in a single module. One new file is added, 
+common/dmextern.c.
+
+AML Debugger: Added a max count argument for the Batch command (which 
+executes multiple predefined methods within the namespace.)
+
+iASL: Updated the compiler documentation (User Reference.) Available at 
+http://www.acpica.org/documentation/. ACPICA BZ 750.
+
+AcpiXtract: Updated for Lint and other formatting changes. Close all open 
+files.
+
+----------------------------------------
+03 September 2009. Summary of changes for version 20090903:
+
+1) ACPI CA Core Subsystem:
+
+For Windows Vista compatibility, added the automatic execution of an _INI 
+method located at the namespace root (\_INI). This method is executed at 
+table load time. This support is in addition to the automatic execution of 
+\_SB._INI. Lin Ming.
+
+Fixed a possible memory leak in the interpreter for AML package objects if 
+the package initializer list is longer than the defined size of the package. 
+This apparently can only happen if the BIOS changes the package size on the 
+fly (seen in a _PSS object), as ASL compilers do not allow this. The 
+interpreter will truncate the package to the defined size (and issue an error 
+message), but previously could leave the extra objects undeleted if they were 
+pre-created during the argument processing (such is the case if the package 
+consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.
+
+Fixed a problem seen when a Buffer or String is stored to itself via ASL. 
+This has been reported in the field. Previously, ACPICA would zero out the 
+buffer/string. Now, the operation is treated as a noop. Provides Windows 
+compatibility. ACPICA BZ 803. Lin Ming.
+
+Removed an extraneous error message for ASL constructs of the form 
+Store(LocalX,LocalX) when LocalX is uninitialized. These curious statements 
+are seen in many BIOSs and are once again treated as NOOPs and no error is 
+emitted when they are encountered. ACPICA BZ 785.
+
+Fixed an extraneous warning message if a _DSM reserved method returns a 
+Package object. _DSM can return any type of object, so validation on the 
+return type cannot be performed. ACPICA BZ 802.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  85.5K Code, 18.0K Data, 103.5K Total
+    Debug Version:     161.6K Code, 50.9K Data, 212.5K Total
+  Current Release:
+    Non-Debug Version:  85.6K Code, 18.0K Data, 103.6K Total
+    Debug Version:     161.7K Code, 50.9K Data, 212.6K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a problem with the use of the Alias operator and Resource 
+Templates. The correct alias is now constructed and no error is emitted. 
+ACPICA BZ 738.
+
+iASL: Implemented the -I option to specify additional search directories for 
+include files. Allows multiple additional search paths for include files. 
+Directories are searched in the order specified on the command line (after 
+the local directory is searched.) ACPICA BZ 800.
+
+iASL: Fixed a problem where the full pathname for include files was not 
+emitted for warnings/errors. This caused the IDE support to not work 
+properly. ACPICA BZ 765.
+
+iASL: Implemented the -@ option to specify a Windows-style response file 
+containing additional command line options. ACPICA BZ 801.
+
+AcpiExec: Added support to load multiple AML files simultaneously (such as a 
+DSDT and multiple SSDTs). Also added support for wildcards within the AML 
+pathname. These features allow all machine tables to be easily loaded and 
+debugged together. ACPICA BZ 804.
+
+Disassembler: Added missing support for disassembly of HEST table Error Bank 
+subtables. 
+
+----------------------------------------
+30 July 2009. Summary of changes for version 20090730:
+
+The ACPI 4.0 implementation for ACPICA is complete with this release.
+
+1) ACPI CA Core Subsystem:
+
+ACPI 4.0: Added header file support for all new and changed ACPI tables. 
+Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new 
+for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT, 
+EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There 
+have been some ACPI 4.0 changes to other existing tables. Split the large 
+actbl1.h header into the existing actbl2.h header. ACPICA BZ 774.
+
+ACPI 4.0: Implemented predefined name validation for all new names. There are 
+31 new names in ACPI 4.0. The predefined validation module was split into two 
+files. The new file is namespace/nsrepair.c. ACPICA BZ 770.
+
+Implemented support for so-called "module-level executable code". This is 
+executable AML code that exists outside of any control method and is intended 
+to be executed at table load time. Although illegal since ACPI 2.0, this type 
+of code still exists and is apparently still being created. Blocks of this 
+code are now detected and executed as intended. Currently, the code blocks 
+must exist under either an If, Else, or While construct; these are the 
+typical cases seen in the field. ACPICA BZ 762. Lin Ming.
+
+Implemented an automatic dynamic repair for predefined names that return 
+nested Package objects. This applies to predefined names that are defined to 
+return a variable-length Package of sub-packages. If the number of sub-
+packages is one, BIOS code is occasionally seen that creates a simple single 
+package with no sub-packages. This code attempts to fix the problem by 
+wrapping a new package object around the existing package. These methods can 
+be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ 
+790.
+
+Fixed a regression introduced in 20090625 for the AcpiGetDevices interface. 
+The _HID/_CID matching was broken and no longer matched IDs correctly. ACPICA 
+BZ 793.
+
+Fixed a problem with AcpiReset where the reset would silently fail if the 
+register was one of the protected I/O ports. AcpiReset now bypasses the port 
+validation mechanism. This may eventually be driven into the AcpiRead/Write 
+interfaces.
+
+Fixed a regression related to the recent update of the AcpiRead/Write 
+interfaces. A sleep/suspend could fail if the optional PM2 Control register 
+does not exist during an attempt to write the Bus Master Arbitration bit. 
+(However, some hosts already delete the code that writes this bit, and the 
+code may in fact be obsolete at this date.) ACPICA BZ 799.
+
+Fixed a problem where AcpiTerminate could fault if inadvertently called twice 
+in succession. ACPICA BZ 795.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+ACPI 4.0: Implemented disassembler support for all new ACPI tables and 
+changes to existing tables. ACPICA BZ 775.
+
+----------------------------------------
+25 June 2009. Summary of changes for version 20090625:
+
+The ACPI 4.0 Specification was released on June 16 and is available at 
+www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will 
+continue for the next few releases.
+
+1) ACPI CA Core Subsystem:
+
+ACPI 4.0: Implemented interpreter support for the IPMI operation region 
+address space. Includes support for bi-directional data buffers and an IPMI 
+address space handler (to be installed by an IPMI device driver.) ACPICA BZ 
+773. Lin Ming.
+
+ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes 
+support in both the header files and the disassembler.
+
+Completed a major update for the AcpiGetObjectInfo external interface. 
+Changes include:
+ - Support for variable, unlimited length HID, UID, and CID strings.
+ - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
+ - Call the _SxW power methods on behalf of a device object.
+ - Determine if a device is a PCI root bridge.
+ - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
+These changes will require an update to all callers of this interface. See 
+the updated ACPICA Programmer Reference for details. One new source file has 
+been added - utilities/utids.c. ACPICA BZ 368, 780.
+
+Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit 
+transfers. The Value parameter has been extended from 32 bits to 64 bits in 
+order to support new ACPI 4.0 tables. These changes will require an update to 
+all callers of these interfaces. See the ACPICA Programmer Reference for 
+details. ACPICA BZ 768.
+
+Fixed several problems with AcpiAttachData. The handler was not invoked when 
+the host node was deleted. The data sub-object was not automatically deleted 
+when the host node was deleted. The interface to the handler had an unused 
+parameter, this was removed. ACPICA BZ 778.
+
+Enhanced the function that dumps ACPI table headers. All non-printable 
+characters in the string fields are now replaced with '?' (Signature, OemId, 
+OemTableId, and CompilerId.) ACPI tables with non-printable characters in 
+these fields are occasionally seen in the field. ACPICA BZ 788.
+
+Fixed a problem with predefined method repair code where the code that 
+attempts to repair/convert an object of incorrect type is only executed on 
+the first time the predefined method is called. The mechanism that disables 
+warnings on subsequent calls was interfering with the repair mechanism. 
+ACPICA BZ 781.
+
+Fixed a possible memory leak in the predefined validation/repair code when a 
+buffer is automatically converted to an expected string object.
+
+Removed obsolete 16-bit files from the distribution and from the current git 
+tree head. ACPICA BZ 776.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  83.4K Code, 17.5K Data, 100.9K Total
+    Debug Version:     158.9K Code, 50.0K Data, 208.9K Total

+    Debug Version:     160.5K Code, 50.6K Data, 211.1K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI 
+operation region keyword. ACPICA BZ 771, 772. Lin Ming.
+
+ACPI 4.0: iASL - implemented compile-time validation support for all new 
+predefined names and control methods (31 total). ACPICA BZ 769.
+
+----------------------------------------
+21 May 2009. Summary of changes for version 20090521:
+
+1) ACPI CA Core Subsystem:
+
+Disabled the preservation of the SCI enable bit in the PM1 control register. 
+The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification to be 
+a "preserved" bit - "OSPM always preserves this bit position", section 
+4.7.3.2.1. However, some machines fail if this bit is in fact preserved 
+because the bit needs to be explicitly set by the OS as a workaround. No 
+machines fail if the bit is not preserved. Therefore, ACPICA no longer 
+attempts to preserve this bit.
+
+Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or 
+incorrectly formed _PRT package could cause a fault. Added validation to 
+ensure that each package element is actually a sub-package.
+
+Implemented a new interface to install or override a single control method, 
+AcpiInstallMethod. This interface is useful when debugging in order to repair 
+an existing method or to install a missing method without having to override 
+the entire ACPI table. See the ACPICA Programmer Reference for use and 
+examples. Lin Ming, Bob Moore.
+
+Fixed several reference count issues with the DdbHandle object that is 
+created from a Load or LoadTable operator. Prevent premature deletion of the 
+object. Also, mark the object as invalid once the table has been unloaded. 
+This is needed because the handle itself may not be deleted after the table 
+unload, depending on whether it has been stored in a named object by the 
+caller. Lin Ming.
+
+Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple 
+mutexes of the same sync level are acquired but then not released in strict 
+opposite order, the internally maintained Current Sync Level becomes confused 
+and can cause subsequent execution errors. ACPICA BZ 471.
+
+Changed the allowable release order for ASL mutex objects. The ACPI 4.0 
+specification has been changed to make the SyncLevel for mutex objects more 
+useful. When releasing a mutex, the SyncLevel of the mutex must now be the 
+same as the current sync level. This makes more sense than the previous rule 
+(SyncLevel less than or equal). This change updates the code to match the 
+specification.
+
+Fixed a problem with the local version of the AcpiOsPurgeCache function. The 
+(local) cache must be locked during all cache object deletions. Andrew 
+Baumann.
+
+Updated the Load operator to use operation region interfaces. This replaces 
+direct memory mapping with region access calls. Now, all region accesses go 
+through the installed region handler as they should.
+
+Simplified and optimized the NsGetNextNode function. Reduced parameter count 
+and reduced code for this frequently used function.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  82.8K Code, 17.5K Data, 100.3K Total
+    Debug Version:     158.0K Code, 49.9K Data, 207.9K Total

+    Debug Version:     158.9K Code, 50.0K Data, 208.9K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some problems 
+with sub-table disassembly and handling invalid sub-tables. Attempt recovery 
+after an invalid sub-table ID.
+
+----------------------------------------
+22 April 2009. Summary of changes for version 20090422:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a compatibility issue with the recently released I/O port protection 
+mechanism. For windows compatibility, 1) On a port protection violation, 
+simply ignore the request and do not return an exception (allow the control 
+method to continue execution.) 2) If only part of the request overlaps a 
+protected port, read/write the individual ports that are not protected. Linux 
+BZ 13036. Lin Ming
+
+Enhanced the execution of the ASL/AML BreakPoint operator so that it actually 
+breaks into the AML debugger if the debugger is present. This matches the 
+ACPI-defined behavior.
+
+Fixed several possible warnings related to the use of the configurable 
+ACPI_THREAD_ID. This type can now be configured as either an integer or a 
+pointer with no warnings. Also fixes several warnings in printf-like 
+statements for the 64-bit build when the type is configured as a pointer. 
+ACPICA BZ 766, 767.
+
+Fixed a number of possible warnings when compiling with gcc 4+ (depending on 
+warning options.) Examples include printf formats, aliasing, unused globals, 
+missing prototypes, missing switch default statements, use of non-ANSI 
+library functions, use of non-ANSI constructs. See generate/unix/Makefile for 
+a list of warning options used with gcc 3 and 4. ACPICA BZ 735.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  82.6K Code, 17.6K Data, 100.2K Total
+    Debug Version:     157.7K Code, 49.9K Data, 207.6K Total
+  Current Release:
+    Non-Debug Version:  82.8K Code, 17.5K Data, 100.3K Total
+    Debug Version:     158.0K Code, 49.9K Data, 207.9K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a generation warning from Bison 2.3 and fixed several warnings on 
+the 64-bit build.
+
+iASL: Fixed a problem where the Unix/Linux versions of the compiler could not 
+correctly digest Windows/DOS formatted files (with CR/LF).
+
+iASL: Added a new option for "quiet mode" (-va) that produces only the 
+compilation summary, not individual errors and warnings. Useful for large 
+batch compilations.
+
+AcpiExec: Implemented a new option (-z) to enable a forced semaphore/mutex 
+timeout that can be used to detect hang conditions during execution of AML 
+code (includes both internal semaphores and AML-defined mutexes and events.)
+
+Added new makefiles for the generation of acpica in a generic unix-like 
+environment. These makefiles are intended to generate the acpica tools and 
+utilities from the original acpica git source tree structure.
+
+Test Suites: Updated and cleaned up the documentation files. Updated the 
+copyrights to 2009, affecting all source files. Use the new version of iASL 
+with quiet mode. Increased the number of available semaphores in the Windows 
+OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, added 
+an alternate implementation of the semaphore timeout to allow aslts to 
+execute fully on Cygwin.
+
+----------------------------------------
+20 March 2009. Summary of changes for version 20090320:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a possible race condition between AcpiWalkNamespace and dynamic table 
+unloads. Added a reader/writer locking mechanism to allow multiple concurrent 
+namespace walks (readers), but block a dynamic table unload until it can gain 
+exclusive write access to the namespace. This fixes a problem where a table 
+unload could (possibly catastrophically) delete the portion of the namespace 
+that is currently being examined by a walk. Adds a new file, utlock.c, that 
+implements the reader/writer lock mechanism. ACPICA BZ 749.
+
+Fixed a regression introduced in version 20090220 where a change to the FADT 
+handling could cause the ACPICA subsystem to access non-existent I/O ports.
+
+Modified the handling of FADT register and table (FACS/DSDT) addresses. The 
+FADT can contain both 32-bit and 64-bit versions of these addresses. 
+Previously, the 64-bit versions were favored, meaning that if both 32 and 64 
+versions were valid, but not equal, the 64-bit version was used. This was 
+found to cause some machines to fail. Now, in this case, the 32-bit version 
+is used instead. This now matches the Windows behavior.
+
+Implemented a new mechanism to protect certain I/O ports. Provides Microsoft 
+compatibility and protects the standard PC I/O ports from access via AML 
+code. Adds a new file, hwvalid.c
+
+Fixed a possible extraneous warning message from the FADT support. The 
+message warns of a 32/64 length mismatch between the legacy and GAS 
+definitions for a register.
+
+Removed the obsolete AcpiOsValidateAddress OSL interface. This interface is 
+made obsolete by the port protection mechanism above. It was previously used 
+to validate the entire address range of an operation region, which could be 
+incorrect if the range included illegal ports, but fields within the 
+operation region did not actually access those ports. Validation is now 
+performed on a per-field basis instead of the entire region.
+
+Modified the handling of the PM1 Status Register ignored bit (bit 11.) 
+Ignored bits must be "preserved" according to the ACPI spec. Usually, this 
+means a read/modify/write when writing to the register. However, for status 
+registers, writing a one means clear the event. Writing a zero means preserve 
+the event (do not clear.) This behavior is clarified in the ACPI 4.0 spec, 
+and the ACPICA code now simply always writes a zero to the ignored bit.
+
+Modified the handling of ignored bits for the PM1 A/B Control Registers. As 
+per the ACPI specification, for the control registers, preserve 
+(read/modify/write) all bits that are defined as either reserved or ignored.
+
+Updated the handling of write-only bits in the PM1 A/B Control Registers. 
+When reading the register, zero the write-only bits as per the ACPI spec. 
+ACPICA BZ 443. Lin Ming.
+
+Removed "Linux" from the list of supported _OSI strings. Linux no longer 
+wants to reply true to this request. The Windows strings are the only paths 
+through the AML that are tested and known to work properly.
+

+
+2) iASL Compiler/Disassembler and Tools:
+
+Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c and 
+aetables.c
+
+----------------------------------------
+20 February 2009. Summary of changes for version 20090220:
+
+1) ACPI CA Core Subsystem:
+
+Optimized the ACPI register locking. Removed locking for reads from the ACPI 
+bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is 
+not required when reading the single-bit registers. The 
+AcpiGetRegisterUnlocked function is no longer needed and has been removed. 
+This will improve performance for reads on these registers. ACPICA BZ 760.
+
+Fixed the parameter validation for AcpiRead/Write. Now return 
+AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS if 
+the register has an address of zero. Previously, these cases simply returned 
+AE_OK. For optional registers such as PM1B status/enable/control, the caller 
+should check for a valid register address before calling. ACPICA BZ 748.
+
+Renamed the external ACPI bit register access functions. Renamed 
+AcpiGetRegister and AcpiSetRegister to clarify the purpose of these 
+functions. The new names are AcpiReadBitRegister and AcpiWriteBitRegister. 
+Also, restructured the code for these functions by simplifying the code path 
+and condensing duplicate code to reduce code size.
+
+Added new functions to transparently handle the possibly split PM1 A/B 
+registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two functions 
+now handle the split registers for PM1 Status, Enable, and Control. ACPICA BZ 
+746.
+
+Added a function to handle the PM1 control registers, AcpiHwWritePm1Control. 
+This function writes both of the PM1 control registers (A/B). These registers 
+are different than the PM1 A/B status and enable registers in that different 
+values can be written to the A/B registers. Most notably, the SLP_TYP bits 
+can be different, as per the values returned from the _Sx predefined methods.
+
+Removed an extra register write within AcpiHwClearAcpiStatus. This function 
+was writing an optional PM1B status register twice. The existing call to the 
+low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 A/B 
+register. ACPICA BZ 751.
+
+Split out the PM1 Status registers from the FADT. Added new globals for these 
+registers (A/B), similar to the way the PM1 Enable registers are handled. 
+Instead of overloading the FADT Event Register blocks. This makes the code 
+clearer and less prone to error.
+
+Fixed the warning message for when the platform contains too many ACPI tables 
+for the default size of the global root table data structure. The calculation 
+for the truncation value was incorrect.
+
+Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this 
+obsolete macro, since it is now a simple reference to ->common.type. There 
+were about 150 invocations of the macro across 41 files. ACPICA BZ 755.
+
+Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as 
+TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to 
+simply SLEEP_TYPE. ACPICA BZ 754.
+
+Conditionally compile the AcpiSetFirmwareWakingVector64 function. This 
+function is only needed on 64-bit host operating systems and is thus not 
+included for 32-bit hosts.
+
+Debug output: print the input and result for invocations of the _OSI reserved 
+control method via the ACPI_LV_INFO debug level. Also, reduced some of the 
+verbosity of this debug level. Len Brown.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Decode the FADT PM_Profile field. Emit ascii names for the 
+various legal performance profiles.
+
+----------------------------------------
+23 January 2009. Summary of changes for version 20090123:
+
+1) ACPI CA Core Subsystem:
+
+Added the 2009 copyright to all module headers and signons. This affects 
+virtually every file in the ACPICA core subsystem, the iASL compiler, and 
+the tools/utilities.
+
+Implemented a change to allow the host to override any ACPI table, including 
+dynamically loaded tables. Previously, only the DSDT could be replaced by the 
+host. With this change, the AcpiOsTableOverride interface is called for each 
+table found in the RSDT/XSDT during ACPICA initialization, and also whenever 
+a table is dynamically loaded via the AML Load operator.
+
+Updated FADT flag definitions, especially the Boot Architecture flags.
+
+Debugger: For the Find command, automatically pad the input ACPI name with 
+underscores if the name is shorter than 4 characters. This enables a match 
+with the actual namespace entry which is itself padded with underscores.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:

+    Debug Version:     157.3K Code, 49.8K Data, 207.1K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fix build error under Bison-2.4.
+
+Dissasembler: Enhanced FADT support. Added decoding of the Boot Architecture 
+flags. Now decode all flags, regardless of the FADT version. Flag output 
+includes the FADT version which first defined each flag.
+
+The iASL -g option now dumps the RSDT to a file (in addition to the FADT and 
+DSDT). Windows only.
+
+----------------------------------------
+04 December 2008. Summary of changes for version 20081204:
+
+1) ACPI CA Core Subsystem:
+
+The ACPICA Programmer Reference has been completely updated and revamped for 
+this release. This includes updates to the external interfaces, OSL 
+interfaces, the overview sections, and the debugger reference.
+
+Several new ACPICA interfaces have been implemented and documented in the 
+programmer reference:
+AcpiReset - Writes the reset value to the FADT-defined reset register.
+AcpiDisableAllGpes - Disable all available GPEs.
+AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs.
+AcpiGetGpeDevice - Get the GPE block device associated with a GPE.
+AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs.
+AcpiRead - Low-level read ACPI register (was HwLowLevelRead.)
+AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.)
+
+Most of the public ACPI hardware-related interfaces have been moved to a new 
+file, components/hardware/hwxface.c
+
+Enhanced the FADT parsing and low-level ACPI register access: The ACPI 
+register lengths within the FADT are now used, and the low level ACPI 
+register access no longer hardcodes the ACPI register lengths. Given that 
+there may be some risk in actually trusting the FADT register lengths, a run-
+time option was added to fall back to the default hardcoded lengths if the 
+FADT proves to contain incorrect values - UseDefaultRegisterWidths. This 
+option is set to true for now, and a warning is issued if a suspicious FADT 
+register length is overridden with the default value.
+
+Fixed a reference count issue in NsRepairObject. This problem was introduced 
+in version 20081031 as part of a fix to repair Buffer objects within 
+Packages. Lin Ming.
+
+Added semaphore support to the Linux/Unix application OS-services layer 
+(OSL). ACPICA BZ 448. Lin Ming.
+
+Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes will 
+be implemented in the OSL, or will binary semaphores be used instead.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  81.7K Code, 17.3K Data,  99.0K Total
+    Debug Version:     156.4K Code, 49.4K Data, 205.8K Total
+  Current Release:
+    Non-Debug Version:  82.3K Code, 17.4K Data,  99.7K Total
+    Debug Version:     157.1K Code, 49.7K Data, 206.8K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Completed the '-e' option to include additional ACPI tables in order to 
+aid with disassembly and External statement generation. ACPICA BZ 742. Lin 
+Ming.
+
+iASL: Removed the "named object in while loop" error. The compiler cannot 
+determine how many times a loop will execute. ACPICA BZ 730.
+
+Disassembler: Implemented support for FADT revision 2 (MS extension). ACPICA 
+BZ 743.
+
+Disassembler: Updates for several ACPI data tables (HEST, EINJ, and MCFG).
+
+----------------------------------------
+31 October 2008. Summary of changes for version 20081031:
+
+1) ACPI CA Core Subsystem:
+
+Restructured the ACPICA header files into public/private. acpi.h now includes 
+only the "public" acpica headers. All other acpica headers are "private" and 
+should not be included by acpica users. One new file, accommon.h is used to 
+include the commonly used private headers for acpica code generation. Future 
+plans include moving all private headers to a new subdirectory.
+
+Implemented an automatic Buffer->String return value conversion for 
+predefined ACPI methods. For these methods (such as _BIF), added automatic 
+conversion for return objects that are required to be a String, but a Buffer 
+was found instead. This can happen when reading string battery data from an 
+operation region, because it used to be difficult to convert the data from 
+buffer to string from within the ASL. Ensures that the host OS is provided 
+with a valid null-terminated string. Linux BZ 11822.
+
+Updated the FACS waking vector interfaces. Split AcpiSetFirmwareWakingVector 
+into two: one for the 32-bit vector, another for the 64-bit vector. This is 
+required because the host OS must setup the wake much differently for each 
+vector (real vs. protected mode, etc.) and the interface itself should not be 
+deciding which vector to use. Also, eliminated the GetFirmwareWakingVector 
+interface, as it served no purpose (only the firmware reads the vector, OS 
+only writes the vector.) ACPICA BZ 731.
+
+Implemented a mechanism to escape infinite AML While() loops. Added a loop 
+counter to force exit from AML While loops if the count becomes too large. 
+This can occur in poorly written AML when the hardware does not respond 
+within a while loop and the loop does not implement a timeout. The maximum 
+loop count is configurable. A new exception code is returned when a loop is 
+broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore.
+
+Optimized the execution of AML While loops. Previously, a control state 
+object was allocated and freed for each execution of the loop. The 
+optimization is to simply reuse the control state for each iteration. This 
+speeds up the raw loop execution time by about 5%.
+
+Enhanced the implicit return mechanism. For Windows compatibility, return an 
+implicit integer of value zero for methods that contain no executable code. 
+Such methods are seen in the field as stubs (presumably), and can cause 
+drivers to fail if they expect a return value. Lin Ming.
+
+Allow multiple backslashes as root prefixes in namepaths. In a fully 
+qualified namepath, allow multiple backslash prefixes. This can happen (and 
+is seen in the field) because of the use of a double-backslash in strings 
+(since backslash is the escape character) causing confusion. ACPICA BZ 739 
+Lin Ming.
+
+Emit a warning if two different FACS or DSDT tables are discovered in the 
+FADT. Checks if there are two valid but different addresses for the FACS and 
+DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.)
+
+Consolidated the method argument count validation code. Merged the code that 
+validates control method argument counts into the predefined validation 
+module. Eliminates possible multiple warnings for incorrect argument counts.
+
+Implemented ACPICA example code. Includes code for ACPICA initialization, 
+handler installation, and calling a control method. Available at 
+source/tools/examples.
+
+Added a global pointer for FACS table to simplify internal FACS access. Use 
+the global pointer instead of using AcpiGetTableByIndex for each FACS access. 
+This simplifies the code for the Global Lock and the Firmware Waking 
+Vector(s).
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Improved disassembly of external method calls. Added the -e option to 
+allow the inclusion of additional ACPI tables to help with the disassembly of 
+method invocations and the generation of external declarations during the 
+disassembly. Certain external method invocations cannot be disassembled 
+properly without the actual declaration of the method. Use the -e option to 
+include the table where the external method(s) are actually declared. Most 
+useful for disassembling SSDTs that make method calls back to the master 
+DSDT. Lin Ming. Example: To disassemble an SSDT with calls to DSDT:  iasl -d 
+-e dsdt.aml ssdt1.aml
+
+iASL: Fix to allow references to aliases within ASL namepaths. Fixes a 
+problem where the use of an alias within a namepath would result in a not 
+found error or cause the compiler to fault. Also now allows forward 
+references from the Alias operator itself. ACPICA BZ 738.
+
+----------------------------------------
+26 September 2008. Summary of changes for version 20080926:
+
+1) ACPI CA Core Subsystem:
+
+Designed and implemented a mechanism to validate predefined ACPI methods and 
+objects. This code validates the predefined ACPI objects (objects whose names 
+start with underscore) that appear in the namespace, at the time they are 
+evaluated. The argument count and the type of the returned object are 
+validated against the ACPI specification. The purpose of this validation is 
+to detect problems with the BIOS-implemented predefined ACPI objects before 
+the results are returned to the ACPI-related drivers. Future enhancements may 
+include actual repair of incorrect return objects where possible. Two new 
+files are nspredef.c and acpredef.h.
+
+Fixed a fault in the AML parser if a memory allocation fails during the Op 
+completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492.
+
+Fixed an issue with implicit return compatibility. This change improves the 
+implicit return mechanism to be more compatible with the MS interpreter. Lin 
+Ming, ACPICA BZ 349.
+
+Implemented support for zero-length buffer-to-string conversions. Allow zero 
+length strings during interpreter buffer-to-string conversions. For example, 
+during the ToDecimalString and ToHexString operators, as well as implicit 
+conversions. Fiodor Suietov, ACPICA BZ 585.
+
+Fixed two possible memory leaks in the error exit paths of 
+AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions are 
+similar in that they use a stack of state objects in order to eliminate 
+recursion. The stack must be fully unwound and deallocated if an error 
+occurs. Lin Ming. ACPICA BZ 383.
+
+Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the global 
+ACPI register table. This bit does not exist and is unused. Lin Ming, Bob 
+Moore ACPICA BZ 442.
+
+Removed the obsolete version number in module headers. Removed the 
+"$Revision" number that appeared in each module header. This version number 
+was useful under SourceSafe and CVS, but has no meaning under git. It is not 
+only incorrect, it could also be misleading.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
+    Debug Version:     153.7K Code, 48.2K Data, 201.9K Total

+
+----------------------------------------
+29 August 2008. Summary of changes for version 20080829:
+
+1) ACPI CA Core Subsystem:
+
+Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type 
+Reference. Changes include the elimination of cheating on the Object field 
+for the DdbHandle subtype, addition of a reference class field to 
+differentiate the various reference types (instead of an AML opcode), and the 
+cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723
+
+Reduce an error to a warning for an incorrect method argument count. 
+Previously aborted with an error if too few arguments were passed to a 
+control method via the external ACPICA interface. Now issue a warning instead 
+and continue. Handles the case where the method inadvertently declares too 
+many arguments, but does not actually use the extra ones. Applies mainly to 
+the predefined methods. Lin Ming. Linux BZ 11032.
+
+Disallow the evaluation of named object types with no intrinsic value. Return 
+AE_TYPE for objects that have no value and therefore evaluation is undefined: 
+Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation of 
+these types were allowed, but an exception would be generated at some point 
+during the evaluation. Now, the error is generated up front.
+
+Fixed a possible memory leak in the AcpiNsGetExternalPathname function 
+(nsnames.c). Fixes a leak in the error exit path.
+
+Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These debug 
+levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and ACPI_EXCEPTION 
+interfaces. Also added ACPI_DB_EVENTS to correspond with the existing 
+ACPI_LV_EVENTS.
+
+Removed obsolete and/or unused exception codes from the acexcep.h header. 
+There is the possibility that certain device drivers may be affected if they 
+use any of these exceptions.
+
+The ACPICA documentation has been added to the public git source tree, under 
+acpica/documents. Included are the ACPICA programmer reference, the iASL 
+compiler reference, and the changes.txt release logfile.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total

+    Debug Version:     153.7K Code, 48.2K Data, 201.9K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Allow multiple argument counts for the predefined _SCP method. ACPI 3.0 
+defines _SCP with 3 arguments. Previous versions defined it with only 1 
+argument. iASL now allows both definitions.
+
+iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for zero-
+length subtables when disassembling ACPI tables. Also fixed a couple of 
+errors where a full 16-bit table type field was not extracted from the input 
+properly.
+
+acpisrc: Improve comment counting mechanism for generating source code 
+statistics. Count first and last lines of multi-line comments as whitespace, 
+not comment lines. Handle Linux legal header in addition to standard acpica 
+header.
+
+----------------------------------------
+
+29 July 2008. Summary of changes for version 20080729:
+
+1) ACPI CA Core Subsystem:
+
+Fix a possible deadlock in the GPE dispatch. Remove call to 
+AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will attempt 
+to acquire the GPE lock but can deadlock since the GPE lock is already held 
+at dispatch time. This code was introduced in version 20060831 as a response 
+to Linux BZ 6881 and has since been removed from Linux.
+
+Add a function to dereference returned reference objects. Examines the return 
+object from a call to AcpiEvaluateObject. Any Index or RefOf references are 
+automatically dereferenced in an attempt to return something useful (these 
+reference types cannot be converted into an external ACPI_OBJECT.) Provides 
+MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105
+
+x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new 
+subtables for the MADT and one new subtable for the SRAT. Includes 
+disassembler and AcpiSrc support. Data from the Intel 64 Architecture x2APIC 
+Specification, June 2008.
+
+Additional error checking for pathname utilities. Add error check after all 
+calls to AcpiNsGetPathnameLength. Add status return from 
+AcpiNsBuildExternalPath and check after all calls. Add parameter validation 
+to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar.
+
+Return status from the global init function AcpiUtGlobalInitialize. This is 
+used by both the kernel subsystem and the utilities such as iASL compiler. 
+The function could possibly fail when the caches are initialized. Yang Yi.
+
+Add a function to decode reference object types to strings. Created for 
+improved error messages. 
+
+Improve object conversion error messages. Better error messages during object 
+conversion from internal to the external ACPI_OBJECT. Used for external calls 
+to AcpiEvaluateObject.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.6K Code, 16.2K Data,  95.8K Total
+    Debug Version:     153.5K Code, 48.2K Data, 201.7K Total
+  Current Release:
+    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
+    Debug Version:     153.9K Code, 48.4K Data, 202.3K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Debugger: fix a possible hang when evaluating non-methods. Fixes a problem 
+introduced in version 20080701. If the object being evaluated (via execute 
+command) is not a method, the debugger can hang while trying to obtain non-
+existent parameters.
+
+iASL: relax error for using reserved "_T_x" identifiers. These names can 
+appear in a disassembled ASL file if they were emitted by the original 
+compiler. Instead of issuing an error or warning and forcing the user to 
+manually change these names, issue a remark instead.
+
+iASL: error if named object created in while loop. Emit an error if any named 
+object is created within a While loop. If allowed, this code will generate a 
+run-time error on the second iteration of the loop when an attempt is made to 
+create the same named object twice. ACPICA bugzilla 730.
+
+iASL: Support absolute pathnames for include files. Add support for absolute 
+pathnames within the Include operator. previously, only relative pathnames 
+were supported.
+
+iASL: Enforce minimum 1 interrupt in interrupt macro and Resource Descriptor. 
+The ACPI spec requires one interrupt minimum. BZ 423
+
+iASL: Handle a missing ResourceSource arg, with a present SourceIndex. 
+Handles the case for the Interrupt Resource Descriptor where
+the ResourceSource argument is omitted but ResourceSourceIndex
+is present. Now leave room for the Index. BZ 426
+
+iASL: Prevent error message if CondRefOf target does not exist. Fixes cases 
+where an error message is emitted if the target does not exist. BZ 516
+
+iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option 
+(get ACPI tables on Windows). This was apparently broken in version 20070919.
+
+AcpiXtract: Handle EOF while extracting data. Correctly handle the case where 
+the EOF happens immediately after the last table in the input file. Print 
+completion message. Previously, no message was displayed in this case.
+
+----------------------------------------
+01 July 2008. Summary of changes for version 20080701:
+
+0) Git source tree / acpica.org
+
+Fixed a problem where a git-clone from http would not transfer the entire 
+source tree.
+
+1) ACPI CA Core Subsystem:
+
+Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one 
+enable bit. Now performs a read-change-write of the enable register instead 
+of simply writing out the cached enable mask. This will prevent inadvertent 
+enabling of GPEs if a rogue GPE is received during initialization (before GPE 
+handlers are installed.)
+
+Implemented a copy for dynamically loaded tables. Previously, dynamically 
+loaded tables were simply mapped - but on some machines this memory is 
+corrupted after suspend. Now copy the table to a local buffer. For the 
+OpRegion case, added checksum verify. Use the table length from the table 
+header, not the region length. For the Buffer case, use the table length 
+also. Dennis Noordsij, Bob Moore. BZ 10734
+
+Fixed a problem where the same ACPI table could not be dynamically loaded and 
+unloaded more than once. Without this change, a table cannot be loaded again 
+once it has been loaded/unloaded one time. The current mechanism does not 
+unregister a table upon an unload. During a load, if the same table is found, 
+this no longer returns an exception. BZ 722
+
+Fixed a problem where the wrong descriptor length was calculated for the 
+EndTag descriptor in 64-bit mode. The "minimal" descriptors such as EndTag 
+are calculated as 12 bytes long, but the actual length in the internal 
+descriptor is 16 because of the round-up to 8 on the 64-bit build. Reported 
+by Linn Crosetto. BZ 728
+
+Fixed a possible memory leak in the Unload operator. The DdbHandle returned 
+by Load() did not have its reference count decremented during unload, leading 
+to a memory leak. Lin Ming. BZ 727
+
+Fixed a possible memory leak when deleting thermal/processor objects. Any 
+associated notify handlers (and objects) were not being deleted. Fiodor 
+Suietov. BZ 506
+
+Fixed the ordering of the ASCII names in the global mutex table to match the 
+actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug only. 
+Vegard Nossum. BZ 726
+
+Enhanced the AcpiGetObjectInfo interface to return the number of required 
+arguments if the object is a control method. Added this call to the debugger 
+so the proper number of default arguments are passed to a method. This 
+prevents a warning when executing methods from AcpiExec.
+
+Added a check for an invalid handle in AcpiGetObjectInfo. Return 
+AE_BAD_PARAMETER if input handle is invalid. BZ 474
+
+Fixed an extraneous warning from exconfig.c on the 64-bit build.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.3K Code, 16.2K Data,  95.5K Total
+    Debug Version:     153.0K Code, 48.2K Data, 201.2K Total

+    Debug Version:     153.5K Code, 48.2K Data, 201.7K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both 
+resource descriptor names.
+
+iASL: Detect invalid ASCII characters in input (windows version). Removed the 
+"-CF" flag from the flex compile, enables correct detection of non-ASCII 
+characters in the input. BZ 441
+
+iASL: Eliminate warning when result of LoadTable is not used. Eliminate the 
+"result of operation not used" warning when the DDB handle returned from 
+LoadTable is not used. The warning is not needed. BZ 590
+
+AcpiExec: Add support for dynamic table load/unload. Now calls _CFG method to 
+pass address of table to the AML. Added option to disable OpRegion simulation 
+to allow creation of an OpRegion with a real address that was passed to _CFG. 
+All of this allows testing of the Load and Unload operators from AcpiExec.
+
+Debugger: update tables command for unloaded tables. Handle unloaded tables 
+and use the standard table header output routine.
+
+----------------------------------------
+09 June 2008. Summary of changes for version 20080609:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a workaround for reversed _PRT entries. A significant number of 
+BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This 
+change dynamically detects and repairs this problem. Provides compatibility 
+with MS ACPI. BZ 6859
+
+Simplified the internal ACPI hardware interfaces to eliminate the locking 
+flag parameter from Register Read/Write. Added a new external interface, 
+AcpiGetRegisterUnlocked.
+
+Fixed a problem where the invocation of a GPE control method could hang. This 
+was a regression introduced in 20080514. The new method argument count 
+validation mechanism can enter an infinite loop when a GPE method is 
+dispatched. Problem fixed by removing the obsolete code that passed GPE block 
+information to the notify handler via the control method parameter pointer.
+
+Fixed a problem where the _SST execution status was incorrectly returned to 
+the caller of AcpiEnterSleepStatePrep. This was a regression introduced in 
+20080514. _SST is optional and a NOT_FOUND exception should never be 
+returned. BZ 716
+
+Fixed a problem where a deleted object could be accessed from within the AML 
+parser. This was a regression introduced in version 20080123 as a fix for the 
+Unload operator. Lin Ming. BZ 10669
+
+Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands 
+and eliminated the use of a negative index in a loop. Operands are now 
+displayed in the correct order, not backwards. This also fixes a regression 
+introduced in 20080514 on 64-bit systems where the elimination of 
+ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715
+
+Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit 
+path did not delete a locally allocated structure.
+
+Updated definitions for the DMAR and SRAT tables to synchronize with the 
+current specifications. Includes disassembler support.
+
+Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect 
+loop termination value was used. Loop terminated on iteration early, missing 
+one mutex. Linn Crosetto
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Implemented support for EisaId() within _CID objects. Now 
+disassemble integer _CID objects back to EisaId invocations, including 
+multiple integers within _CID packages. Includes single-step support for 
+debugger also.
+
+Disassembler: Added support for DMAR and SRAT table definition changes.
+
+----------------------------------------
+14 May 2008. Summary of changes for version 20080514:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where GPEs were enabled too early during the ACPICA 
+initialization. This could lead to "handler not installed" errors on some 
+machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This 
+ensures that all operation regions and devices throughout the namespace have 
+been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916.
+
+Implemented a change to the enter sleep code. Moved execution of the _GTS 
+method to just before setting sleep enable bit. The execution was moved from 
+AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed 
+immediately before the SLP_EN bit is set, as per the ACPI specification. 
+Luming Yu, BZ 1653.
+
+Implemented a fix to disable unknown GPEs (2nd version). Now always disable 
+the GPE, even if ACPICA thinks that that it is already disabled. It is 
+possible that the AML or some other code has enabled the GPE unbeknownst to 
+the ACPICA code.
+
+Fixed a problem with the Field operator where zero-length fields would return 
+an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length ASL 
+field declarations in Field(), BankField(), and IndexField(). BZ 10606.
+
+Implemented a fix for the Load operator, now load the table at the namespace 
+root. This reverts a change introduced in version 20071019. The table is now 
+loaded at the namespace root even though this goes against the ACPI 
+specification. This provides compatibility with other ACPI implementations. 
+The ACPI specification will be updated to reflect this in ACPI 4.0. Lin Ming.
+
+Fixed a problem where ACPICA would not Load() tables with unusual signatures. 
+Now ignore ACPI table signature for Load() operator. Only "SSDT" is 
+acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. 
+Therefore, signature validation is worthless. Apparently MS ACPI accepts such 
+signatures, ACPICA must be compatible. BZ 10454.
+
+Fixed a possible negative array index in AcpiUtValidateException. Added NULL 
+fields to the exception string arrays to eliminate a -1 subtraction on the 
+SubStatus field.
+
+Updated the debug tracking macros to reduce overall code and data size. 
+Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings 
+instead of pointers to static strings. Jan Beulich and Bob Moore.
+
+Implemented argument count checking in control method invocation via 
+AcpiEvaluateObject. Now emit an error if too few arguments, warning if too 
+many. This applies only to extern programmatic control method execution, not 
+method-to-method calls within the AML. Lin Ming.
+
+Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no 
+longer needed, especially with the removal of 16-bit support. It was replaced 
+mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit on 
+32/64-bit platforms is required.
+
+Added the C const qualifier for appropriate string constants -- mostly 
+MODULE_NAME and printf format strings. Jan Beulich.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has a 
+much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  80.0K Code, 17.4K Data,  97.4K Total
+    Debug Version:     159.4K Code, 64.4K Data, 223.8K Total

+    Debug Version:     153.3K Code, 48.3K Data, 201.6K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Implemented ACPI table revision ID validation in the disassembler. Zero is 
+always invalid. For DSDTs, the ID controls the interpreter integer width. 1 
+means 32-bit and this is unusual. 2 or greater is 64-bit.
+
+----------------------------------------
+21 March 2008. Summary of changes for version 20080321:
+
+1) ACPI CA Core Subsystem:
+
+Implemented an additional change to the GPE support in order to suppress 
+spurious or stray GPEs. The AcpiEvDisableGpe function will now permanently 
+disable incoming GPEs that are neither enabled nor disabled -- meaning that 
+the GPE is unknown to the system. This should prevent future interrupt floods 
+from that GPE. BZ 6217 (Zhang Rui)
+
+Fixed a problem where NULL package elements were not returned to the 
+AcpiEvaluateObject interface correctly. The element was simply ignored 
+instead of returning a NULL ACPI_OBJECT package element, potentially causing 
+a buffer overflow and/or confusing the caller who expected a fixed number of 
+elements. BZ 10132 (Lin Ming, Bob Moore)
+
+Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, Dword, 
+Qword), Field, BankField, and IndexField operators when invoked from inside 
+an executing control method. In this case, these operators created namespace 
+nodes that were incorrectly left marked as permanent nodes instead of 
+temporary nodes. This could cause a problem if there is race condition 
+between an exiting control method and a running namespace walk. (Reported by 
+Linn Crosetto)
+
+Fixed a problem where the CreateField and CreateXXXField operators would 
+incorrectly allow duplicate names (the name of the field) with no exception 
+generated.
+
+Implemented several changes for Notify handling. Added support for new Notify 
+values (ACPI 2.0+) and improved the Notify debug output. Notify on 
+PowerResource objects is no longer allowed, as per the ACPI specification. 
+(Bob Moore, Zhang Rui)
+
+All Reference Objects returned via the AcpiEvaluateObject interface are now 
+marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved for 
+NULL objects - either NULL package elements or unresolved named references.
+
+Fixed a problem where an extraneous debug message was produced for package 
+objects (when debugging enabled). The message "Package List length larger 
+than NumElements count" is now produced in the correct case, and is now an 
+error message rather than a debug message. Added a debug message for the 
+opposite case, where NumElements is larger than the Package List (the package 
+will be padded out with NULL elements as per the ACPI spec.)
+
+Implemented several improvements for the output of the ASL "Debug" object to 
+clarify and keep all data for a given object on one output line.
+
+Fixed two size calculation issues with the variable-length Start Dependent 
+resource descriptor.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a problem with the use of the Switch operator where execution of the 
+containing method by multiple concurrent threads could cause an 
+AE_ALREADY_EXISTS exception. This is caused by the fact that there is no 
+actual Switch opcode, it must be simulated with local named temporary 
+variables and if/else pairs. The solution chosen was to mark any method that 
+uses Switch as Serialized, thus preventing multiple thread entries. BZ 469.
+
+----------------------------------------
+13 February 2008. Summary of changes for version 20080213:
+
+1) ACPI CA Core Subsystem:
+
+Implemented another MS compatibility design change for GPE/Notify handling. 
+GPEs are now cleared/enabled asynchronously to allow all pending notifies to 
+complete first. It is expected that the OSL will queue the enable request 
+behind all pending notify requests (may require changes to the local host OSL 
+in AcpiOsExecute). Alexey Starikovskiy.
+
+Fixed a problem where buffer and package objects passed as arguments to a 
+control method via the external AcpiEvaluateObject interface could cause an 
+AE_AML_INTERNAL exception depending on the order and type of operators 
+executed by the target control method.
+
+Fixed a problem where resource descriptor size optimization could cause a 
+problem when a _CRS resource template is passed to a _SRS method. The _SRS 
+resource template must use the same descriptors (with the same size) as 
+returned from _CRS. This change affects the following resource descriptors: 
+IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 9487)
+
+Fixed a problem where a CopyObject to RegionField, BankField, and IndexField 
+objects did not perform an implicit conversion as it should. These types must 
+retain their initial type permanently as per the ACPI specification. However, 
+a CopyObject to all other object types should not perform an implicit 
+conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388
+
+Fixed a problem with the AcpiGetDevices interface where the mechanism to 
+match device CIDs did not examine the entire list of available CIDs, but 
+instead aborted on the first non-matching CID. Andrew Patterson.
+
+Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro was 
+inadvertently changed to return a 16-bit value instead of a 32-bit value, 
+truncating the upper dword of a 64-bit value. This macro is only used to 
+display debug output, so no incorrect calculations were made. Also, 
+reimplemented the macro so that a 64-bit shift is not performed by 
+inefficient compilers.
+
+Added missing va_end statements that should correspond with each va_start 
+statement.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+Implemented full disassembler support for the following new ACPI tables: 
+BERT, EINJ, and ERST. Implemented partial disassembler support for the 
+complicated HEST table. These tables support the Windows Hardware Error 
+Architecture (WHEA).
+
+----------------------------------------
+23 January 2008. Summary of changes for version 20080123:
+
+1) ACPI CA Core Subsystem:
+
+Added the 2008 copyright to all module headers and signons. This affects 
+virtually every file in the ACPICA core subsystem, the iASL compiler, and 
+the tools/utilities.
+
+Fixed a problem with the SizeOf operator when used with Package and Buffer 
+objects. These objects have deferred execution for some arguments, and the 
+execution is now completed before the SizeOf is executed. This problem caused 
+unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) BZ 
+9558
+
+Implemented an enhancement to the interpreter "slack mode". In the absence of 
+an explicit return or an implicitly returned object from the last executed 
+opcode, a control method will now implicitly return an integer of value 0 for 
+Microsoft compatibility. (Lin Ming) BZ 392
+
+Fixed a problem with the Load operator where an exception was not returned in 
+the case where the table is already loaded. (Lin Ming) BZ 463
+
+Implemented support for the use of DDBHandles as an Indexed Reference, as per 
+the ACPI spec. (Lin Ming) BZ 486
+
+Implemented support for UserTerm (Method invocation) for the Unload operator 
+as per the ACPI spec. (Lin Ming) BZ 580
+
+Fixed a problem with the LoadTable operator where the OemId and OemTableId 
+input strings could cause unexpected failures if they were shorter than the 
+maximum lengths allowed. (Lin Ming, Bob Moore) BZ 576
+
+Implemented support for UserTerm (Method invocation) for the Unload operator 
+as per the ACPI spec. (Lin Ming) BZ 580
+
+Implemented header file support for new ACPI tables - BERT, ERST, EINJ, HEST, 
+IBFT, UEFI, WDAT. Disassembler support is forthcoming.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+    Debug Version:     159.0K Code, 63.8K Data, 222.8K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+Implemented support in the disassembler for checksum validation on incoming 
+binary DSDTs and SSDTs. If incorrect, a message is displayed within the table 
+header dump at the start of the disassembly.
+
+Implemented additional debugging information in the namespace listing file 
+created during compilation. In addition to the namespace hierarchy, the full 
+pathname to each namespace object is displayed.
+
+Fixed a problem with the disassembler where invalid ACPI tables could cause 
+faults or infinite loops.
+
+Fixed an unexpected parse error when using the optional "parameter types" 
+list in a control method declaration. (Lin Ming) BZ 397
+
+Fixed a problem where two External declarations with the same name did not 
+cause an error (Lin Ming) BZ 509
+
+Implemented support for full TermArgs (adding Argx, Localx and method 
+invocation) for the ParameterData parameter to the LoadTable operator. (Lin 
+Ming) BZ 583,587
+
+----------------------------------------
+19 December 2007. Summary of changes for version 20071219:
+
+1) ACPI CA Core Subsystem:
+
+Implemented full support for deferred execution for the TermArg string 
+arguments for DataTableRegion. This enables forward references and full 
+operand resolution for the three string arguments. Similar to OperationRegion 
+deferred argument execution.) Lin Ming. BZ 430
+
+Implemented full argument resolution support for the BankValue argument to 
+BankField. Previously, only constants were supported, now any TermArg may be 
+used. Lin Ming BZ 387, 393
+
+Fixed a problem with AcpiGetDevices where the search of a branch of the 
+device tree could be terminated prematurely. In accordance with the ACPI 
+specification, the search down the current branch is terminated if a device 
+is both not present and not functional (instead of just not present.) Yakui 
+Zhao.
+
+Fixed a problem where "unknown" GPEs could be allowed to fire repeatedly if 
+the underlying AML code changed the GPE enable registers. Now, any unknown 
+incoming GPE (no _Lxx/_Exx method and not the EC GPE) is immediately disabled 
+instead of simply ignored. Rui Zhang.
+
+Fixed a problem with Index Fields where the Index register was incorrectly 
+limited to a maximum of 32 bits. Now any size may be used.
+
+Fixed a couple memory leaks associated with "implicit return" objects when 
+the AML Interpreter slack mode is enabled. Lin Ming BZ 349
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+----------------------------------------
+14 November 2007. Summary of changes for version 20071114:
+
+1) ACPI CA Core Subsystem:
+
+Implemented event counters for each of the Fixed Events, the ACPI SCI 
+(interrupt) itself, and control methods executed. Named 
+AcpiFixedEventCount[], AcpiSciCount, and AcpiMethodCount respectively. These 
+should be useful for debugging and statistics.
+
+Implemented a new external interface, AcpiGetStatistics, to retrieve the 
+contents of the various event counters. Returns the current values for 
+AcpiSciCount, AcpiGpeCount, the AcpiFixedEventCount array, and 
+AcpiMethodCount. The interface can be expanded in the future if new counters 
+are added. Device drivers should use this interface rather than access the 
+counters directly.
+
+Fixed a problem with the FromBCD and ToBCD operators. With some compilers, 
+the ShortDivide function worked incorrectly, causing problems with the BCD 
+functions with large input values. A truncation from 64-bit to 32-bit 
+inadvertently occurred. Internal BZ 435. Lin Ming
+
+Fixed a problem with Index references passed as method arguments. References 
+passed as arguments to control methods were dereferenced immediately (before 
+control was passed to the called method). The references are now correctly 
+passed directly to the called method. BZ 5389. Lin Ming
+
+Fixed a problem with CopyObject used in conjunction with the Index operator. 
+The reference was incorrectly dereferenced before the copy. The reference is 
+now correctly copied. BZ 5391. Lin Ming
+
+Fixed a problem with Control Method references within Package objects. These 
+references are now correctly generated. This completes the package 
+construction overhaul that began in version 20071019.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+
+2) iASL Compiler/Disassembler and Tools:
+
+The AcpiExec utility now installs handlers for all of the predefined 
+Operation Region types. New types supported are: PCI_Config, CMOS, and 
+PCIBARTarget.
+
+Fixed a problem with the 64-bit version of AcpiExec where the extended (64-
+bit) address fields for the DSDT and FACS within the FADT were not being 
+used, causing truncation of the upper 32-bits of these addresses. Lin Ming 
+and Bob Moore
+
+----------------------------------------
+19 October 2007. Summary of changes for version 20071019:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem with the Alias operator when the target of the alias is a 
+named ASL operator that opens a new scope -- Scope, Device, PowerResource, 
+Processor, and ThermalZone. In these cases, any children of the original 
+operator could not be accessed via the alias, potentially causing unexpected 
+AE_NOT_FOUND exceptions. (BZ 9067)
+
+Fixed a problem with the Package operator where all named references were 
+created as object references and left otherwise unresolved. According to the 
+ACPI specification, a Package can only contain Data Objects or references to 
+control methods. The implication is that named references to Data Objects 
+(Integer, Buffer, String, Package, BufferField, Field) should be resolved 
+immediately upon package creation. This is the approach taken with this 
+change. References to all other named objects (Methods, Devices, Scopes, 
+etc.) are all now properly created as reference objects. (BZ 5328)
+
+Reverted a change to Notify handling that was introduced in version 
+20070508. This version changed the Notify handling from asynchronous to 
+fully synchronous (Device driver Notify handling with respect to the Notify 
+ASL operator). It was found that this change caused more problems than it 
+solved and was removed by most users.
+
+Fixed a problem with the Increment and Decrement operators where the type of 
+the target object could be unexpectedly and incorrectly changed. (BZ 353) 
+Lin Ming.
+
+Fixed a problem with the Load and LoadTable operators where the table 
+location within the namespace was ignored. Instead, the table was always 
+loaded into the root or current scope. Lin Ming.
+
+Fixed a problem with the Load operator when loading a table from a buffer 
+object. The input buffer was prematurely zeroed and/or deleted. (BZ 577)
+
+Fixed a problem with the Debug object where a store of a DdbHandle reference 
+object to the Debug object could cause a fault.
+
+Added a table checksum verification for the Load operator, in the case where 
+the load is from a buffer. (BZ 578).
+
+Implemented additional parameter validation for the LoadTable operator. The 
+length of the input strings SignatureString, OemIdString, and OemTableId are 
+now checked for maximum lengths. (BZ 582) Lin Ming.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+    Debug Version:     157.2K Code, 63.4K Data, 220.6K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem where if a single file was specified and the file did not 
+exist, no error message was emitted. (Introduced with wildcard support in 
+version 20070917.)
+
+----------------------------------------
+19 September 2007. Summary of changes for version 20070919:
+
+1) ACPI CA Core Subsystem:
+
+Designed and implemented new external interfaces to install and remove 
+handlers for ACPI table-related events. Current events that are defined are 
+LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as 
+they are dynamically loaded and unloaded. See AcpiInstallTableHandler and 
+AcpiRemoveTableHandler. (Lin Ming and Bob Moore)
+
+Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag 
+(acpi_serialized option on Linux) could cause some systems to hang during 
+initialization. (Bob Moore) BZ 8171
+
+Fixed a problem where objects of certain types (Device, ThermalZone, 
+Processor, PowerResource) can be not found if they are declared and 
+referenced from within the same control method (Lin Ming) BZ 341
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+

+    Non-Debug Version:  78.3K Code, 17.0K Data,  95.3K Total
+    Debug Version:     156.3K Code, 63.1K Data, 219.4K Total

+    Debug Version:     156.7K Code, 63.2K Data, 219.9K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Implemented support to allow multiple files to be compiled/disassembled in a 
+single invocation. This includes command line wildcard support for both the 
+Windows and Unix versions of the compiler. This feature simplifies the 
+disassembly and compilation of multiple ACPI tables in a single directory.
+
+----------------------------------------
+08 May 2007. Summary of changes for version 20070508:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a Microsoft compatibility design change for the handling of the 
+Notify AML operator. Previously, notify handlers were dispatched and 
+executed completely asynchronously in a deferred thread. The new design 
+still executes the notify handlers in a different thread, but the original 
+thread that executed the Notify() now waits at a synchronization point for 
+the notify handler to complete. Some machines depend on a synchronous Notify 
+operator in order to operate correctly.
+
+Implemented support to allow Package objects to be passed as method 
+arguments to the external AcpiEvaluateObject interface. Previously, this 
+would return the AE_NOT_IMPLEMENTED exception. This feature had not been 
+implemented since there were no reserved control methods that required it 
+until recently.
+
+Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that 
+contained invalid non-zero values in reserved fields could cause later 
+failures because these fields have meaning in later revisions of the FADT. 
+For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The fields 
+are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.)
+
+Fixed a problem where the Global Lock handle was not properly updated if a 
+thread that acquired the Global Lock via executing AML code then attempted 
+to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by Joe 
+Liu.
+
+Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list 
+could be corrupted if the interrupt being removed was at the head of the 
+list. Reported by Linn Crosetto.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+----------------------------------------
+20 March 2007. Summary of changes for version 20070320:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a change to the order of interpretation and evaluation of AML 
+operand objects within the AML interpreter. The interpreter now evaluates 
+operands in the order that they appear in the AML stream (and the 
+corresponding ASL code), instead of in the reverse order (after the entire 
+operand list has been parsed). The previous behavior caused several subtle 
+incompatibilities with the Microsoft AML interpreter as well as being 
+somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov.
+
+Implemented a change to the ACPI Global Lock support. All interfaces to the 
+global lock now allow the same thread to acquire the lock multiple times. 
+This affects the AcpiAcquireGlobalLock external interface to the global lock 
+as well as the internal use of the global lock to support AML fields -- a 
+control method that is holding the global lock can now simultaneously access 
+AML fields that require global lock protection. Previously, in both cases, 
+this would have resulted in an AE_ALREADY_ACQUIRED exception. The change to 
+AcpiAcquireGlobalLock is of special interest to drivers for the Embedded 
+Controller. There is no change to the behavior of the AML Acquire operator, 
+as this can already be used to acquire a mutex multiple times by the same 
+thread. BZ 8066. With assistance from Alexey Starikovskiy.
+
+Fixed a problem where invalid objects could be referenced in the AML 
+Interpreter after error conditions. During operand evaluation, ensure that 
+the internal "Return Object" field is cleared on error and only valid 
+pointers are stored there. Caused occasional access to deleted objects that 
+resulted in "large reference count" warning messages. Valery Podrezov.
+
+Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur on 
+deeply nested control method invocations. BZ 7873, local BZ 487. Valery 
+Podrezov.
+
+Fixed an internal problem with the handling of result objects on the 
+interpreter result stack. BZ 7872. Valery Podrezov.
+
+Removed obsolete code that handled the case where AML_NAME_OP is the target 
+of a reference (Reference.Opcode). This code was no longer necessary. BZ 
+7874. Valery Podrezov.
+
+Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This was a 
+remnant from the previously discontinued 16-bit support.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+Added the 2007 copyright to all module headers and signons. This affects 
+virtually every file in the ACPICA core subsystem, the iASL compiler, and 
+the utilities.
+
+Implemented a fix for an incorrect parameter passed to AcpiTbDeleteTable 
+during a table load. A bad pointer was passed in the case where the DSDT is 
+overridden, causing a fault in this case.
+
+Example Code and Data Size: These are the sizes for the OS-independent

+----------------------------------------
+15 December 2006. Summary of changes for version 20061215:
+
+1) ACPI CA Core Subsystem:
+
+Support for 16-bit ACPICA has been completely removed since it is no longer 
+necessary and it clutters the code. All 16-bit macros, types, and 
+conditional compiles have been removed, cleaning up and simplifying the code 
+across the entire subsystem. DOS support is no longer needed since the 
+bootable Linux firmware kit is now available.
+
+The handler for the Global Lock is now removed during AcpiTerminate to 
+enable a clean subsystem restart, via the implementation of the 
+AcpiEvRemoveGlobalLockHandler function. (With assistance from Joel Bretz, 
+HP)
+
+Implemented enhancements to the multithreading support within the debugger 
+to enable improved multithreading debugging and evaluation of the subsystem. 
+(Valery Podrezov)
+
+Debugger: Enhanced the Statistics/Memory command to emit the total (maximum) 
+memory used during the execution, as well as the maximum memory consumed by 
+each of the various object types. (Valery Podrezov)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+----------------------------------------
+09 November 2006. Summary of changes for version 20061109:
+
+1) ACPI CA Core Subsystem:
+
+Optimized the Load ASL operator in the case where the source operand is an 
+operation region. Simply map the operation region memory, instead of 
+performing a bytewise read. (Region must be of type SystemMemory, see 
+below.)
+
+Fixed the Load ASL operator for the case where the source operand is a 
+region field. A buffer object is also allowed as the source operand. BZ 480
+
+Fixed a problem where the Load ASL operator allowed the source operand to be 
+an operation region of any type. It is now restricted to regions of type 
+SystemMemory, as per the ACPI specification. BZ 481
+
+Additional cleanup and optimizations for the new Table Manager code.
+
+AcpiEnable will now fail if all of the required ACPI tables are not loaded 
+(FADT, FACS, DSDT). BZ 477
+
+Added #pragma pack(8/4) to acobject.h to ensure that the structures in this 
+header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been 
+manually optimized to be aligned and will not work if it is byte-packed. 
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a problem where the presence of the _OSI predefined control method 
+within complex expressions could cause an internal compiler error.
+
+AcpiExec: Implemented full region support for multiple address spaces. 
+SpaceId is now part of the REGION object. BZ 429
+
+----------------------------------------
+11 October 2006. Summary of changes for version 20061011:
+
+1) ACPI CA Core Subsystem:
+
+Completed an AML interpreter performance enhancement for control method 
+execution. Previously a 2-pass parse/execution, control methods are now 
+completely parsed and executed in a single pass. This improves overall 
+interpreter performance by ~25%, reduces code size, and reduces CPU stack 
+use. (Valery Podrezov + interpreter changes in version 20051202 that 
+eliminated namespace loading during the pass one parse.)
+
+Implemented _CID support for PCI Root Bridge detection. If the _HID does not 
+match the predefined PCI Root Bridge IDs, the _CID list (if present) is now 
+obtained and also checked for an ID match.
+
+Implemented additional support for the PCI _ADR execution: upsearch until a 
+device scope is found before executing _ADR. This allows PCI_Config 
+operation regions to be declared locally within control methods underneath 
+PCI device objects.
+
+Fixed a problem with a possible race condition between threads executing 
+AcpiWalkNamespace and the AML interpreter. This condition was removed by 
+modifying AcpiWalkNamespace to (by default) ignore all temporary namespace 
+entries created during any concurrent control method execution. An 
+additional namespace race condition is known to exist between 
+AcpiWalkNamespace and the Load/Unload ASL operators and is still under 
+investigation.
+
+Restructured the AML ParseLoop function, breaking it into several 
+subfunctions in order to reduce CPU stack use and improve maintainability. 
+(Mikhail Kouzmich)
+
+AcpiGetHandle: Fix for parameter validation to detect invalid combinations 
+of prefix handle and pathname. BZ 478
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+2) iASL Compiler/Disassembler and Tools:
+
+Ported the -g option (get local ACPI tables) to the new ACPICA Table Manager 
+to restore original behavior.
+
+----------------------------------------
+27 September 2006. Summary of changes for version 20060927:
+
+1) ACPI CA Core Subsystem:
+
+Removed the "Flags" parameter from AcpiGetRegister and AcpiSetRegister. 
+These functions now use a spinlock for mutual exclusion and the interrupt 
+level indication flag is not needed.
+
+Fixed a problem with the Global Lock where the lock could appear to be 
+obtained before it is actually obtained. The global lock semaphore was 
+inadvertently created with one unit instead of zero units. (BZ 464) Fiodor 
+Suietov.
+
+Fixed a possible memory leak and fault in AcpiExResolveObjectToValue during 
+a read from a buffer or region field. (BZ 458) Fiodor Suietov.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  77.9K Code, 17.1K Data,  95.0K Total
+    Debug Version:     154.7K Code, 63.0K Data, 217.7K Total
+  Current Release:
+    Non-Debug Version:  77.9K Code, 17.1K Data,  95.0K Total
+    Debug Version:     154.6K Code, 63.0K Data, 217.6K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a compilation problem with the pre-defined Resource Descriptor field 
+names where an "object does not exist" error could be incorrectly generated 
+if the parent ResourceTemplate pathname places the template within a 
+different namespace scope than the current scope. (BZ 7212)
+
+Fixed a problem where the compiler could hang after syntax errors detected 
+in an ElseIf construct. (BZ 453)
+
+Fixed a problem with the AmlFilename parameter to the DefinitionBlock() 
+operator. An incorrect output filename was produced when this parameter was 
+a null string (""). Now, the original input filename is used as the AML 
+output filename, with an ".aml" extension.
+
+Implemented a generic batch command mode for the AcpiExec utility (execute 
+any AML debugger command) (Valery Podrezov).
+
+----------------------------------------
+12 September 2006. Summary of changes for version 20060912:
+
+1) ACPI CA Core Subsystem:
+
+Enhanced the implementation of the "serialized mode" of the interpreter 
+(enabled via the AcpiGbl_AllMethodsSerialized flag.) When this mode is 
+specified, instead of creating a serialization semaphore per control method, 
+the interpreter lock is simply no longer released before a blocking 
+operation during control method execution. This effectively makes the AML 
+Interpreter single-threaded. The overhead of a semaphore per-method is 
+eliminated.
+
+Fixed a regression where an error was no longer emitted if a control method 
+attempts to create 2 objects of the same name. This once again returns 
+AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism that 
+will dynamically serialize the control method to possible prevent future 
+errors. (BZ 440)
+
+Integrated a fix for a problem with PCI Express HID detection in the PCI 
+Config Space setup procedure. (BZ 7145)
+
+Moved all FADT-related functions to a new file, tbfadt.c. Eliminated the 
+AcpiHwInitialize function - the FADT registers are now validated when the 
+table is loaded.
+
+Added two new warnings during FADT verification - 1) if the FADT is larger 
+than the largest known FADT version, and 2) if there is a mismatch between a 
+32-bit block address and the 64-bit X counterpart (when both are non-zero.)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  77.9K Code, 16.7K Data,  94.6K Total
+    Debug Version:     154.9K Code, 62.6K Data, 217.5K Total
+  Current Release:
+    Non-Debug Version:  77.9K Code, 17.1K Data,  95.0K Total
+    Debug Version:     154.7K Code, 63.0K Data, 217.7K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a problem with the implementation of the Switch() operator where the 
+temporary variable was declared too close to the actual Switch, instead of 
+at method level. This could cause a problem if the Switch() operator is 
+within a while loop, causing an error on the second iteration. (BZ 460)
+
+Disassembler - fix for error emitted for unknown type for target of scope 
+operator. Now, ignore it and continue.
+
+Disassembly of an FADT now verifies the input FADT and reports any errors 
+found. Fix for proper disassembly of full-sized (ACPI 2.0) FADTs.
+
+Disassembly of raw data buffers with byte initialization data now prefixes 
+each output line with the current buffer offset.
+
+Disassembly of ASF! table now includes all variable-length data fields at 
+the end of some of the subtables.
+
+The disassembler now emits a comment if a buffer appears to be a 
+ResourceTemplate, but cannot be disassembled as such because the EndTag does 
+not appear at the very end of the buffer.
+
+AcpiExec - Added the "-t" command line option to enable the serialized mode 
+of the AML interpreter.
+
+----------------------------------------
+31 August 2006. Summary of changes for version 20060831:
+
+1) ACPI CA Core Subsystem:
+
+Miscellaneous fixes for the Table Manager:
+- Correctly initialize internal common FADT for all 64-bit "X" fields
+- Fixed a couple table mapping issues during table load
+- Fixed a couple alignment issues for IA64
+- Initialize input array to zero in AcpiInitializeTables
+- Additional parameter validation for AcpiGetTable, AcpiGetTableHeader, 
+AcpiGetTableByIndex
+
+Change for GPE support: when a "wake" GPE is received, all wake GPEs are now 
+immediately disabled to prevent the waking GPE from firing again and to 
+prevent other wake GPEs from interrupting the wake process.
+
+Added the AcpiGpeCount global that tracks the number of processed GPEs, to 
+be used for debugging systems with a large number of ACPI interrupts.
+
+Implemented support for the "DMAR" ACPI table (DMA Redirection Table) in 
+both the ACPICA headers and the disassembler.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+----------------------------------------
+23 August 2006. Summary of changes for version 20060823:
+
+1) ACPI CA Core Subsystem:
+
+The Table Manager component has been completely redesigned and 
+reimplemented. The new design is much simpler, and reduces the overall code 
+and data size of the kernel-resident ACPICA by approximately 5%. Also, it is 
+now possible to obtain the ACPI tables very early during kernel 
+initialization, even before dynamic memory management is initialized. 
+(Alexey Starikovskiy, Fiodor Suietov, Bob Moore)
+
+Obsolete ACPICA interfaces:
+
+- AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel init 
+time).
+- AcpiLoadTable: Not needed.
+- AcpiUnloadTable: Not needed.
+
+New ACPICA interfaces:
+
+- AcpiInitializeTables: Must be called before the table manager can be used.
+- AcpiReallocateRootTable: Used to transfer the root table to dynamically 
+allocated memory after it becomes available.
+- AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI tables 
+in the RSDT/XSDT.
+
+Other ACPICA changes:
+
+- AcpiGetTableHeader returns the actual mapped table header, not a copy. Use 
+AcpiOsUnmapMemory to free this mapping.
+- AcpiGetTable returns the actual mapped table. The mapping is managed 
+internally and must not be deleted by the caller. Use of this interface 
+causes no additional dynamic memory allocation.
+- AcpiFindRootPointer: Support for physical addressing has been eliminated, 
+it appeared to be unused.
+- The interface to AcpiOsMapMemory has changed to be consistent with the 
+other allocation interfaces.
+- The interface to AcpiOsGetRootPointer has changed to eliminate unnecessary 
+parameters.
+- ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 64-
+bit platforms. Was previously 64 bits on all platforms.
+- The interface to the ACPI Global Lock acquire/release macros have changed 
+slightly since ACPICA no longer keeps a local copy of the FACS with a 
+constructed pointer to the actual global lock.
+
+Porting to the new table manager:
+
+- AcpiInitializeTables: Must be called once, and can be called anytime 
+during the OS initialization process. It allows the host to specify an area 
+of memory to be used to store the internal version of the RSDT/XSDT (root 
+table). This allows the host to access ACPI tables before memory management 
+is initialized and running.
+- AcpiReallocateRootTable: Can be called after memory management is running 
+to copy the root table to a dynamically allocated array, freeing up the 
+scratch memory specified in the call to AcpiInitializeTables.
+- AcpiSubsystemInitialize: This existing interface is independent of the 
+Table Manager, and does not have to be called before the Table Manager can 
+be used, it only must be called before the rest of ACPICA can be used.
+- ACPI Tables: Some changes have been made to the names and structure of the 
+actbl.h and actbl1.h header files and may require changes to existing code. 
+For example, bitfields have been completely removed because of their lack of 
+portability across C compilers.
+- Update interfaces to the Global Lock acquire/release macros if local 
+versions are used. (see acwin.h)
+
+Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c
+
+New files: tbfind.c
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+----------------------------------------
+21 July 2006. Summary of changes for version 20060721:
+
+1) ACPI CA Core Subsystem:
+
+The full source code for the ASL test suite used to validate the iASL 
+compiler and the ACPICA core subsystem is being released with the ACPICA 
+source for the first time. The source is contained in a separate package and 
+consists of over 1100 files that exercise all ASL/AML operators. The package 
+should appear on the Intel/ACPI web site shortly. (Valery Podrezov, Fiodor 
+Suietov)
+
+Completed a new design and implementation for support of the ACPI Global 
+Lock. On the OS side, the global lock is now treated as a standard AML 
+mutex. Previously, multiple OS threads could "acquire" the global lock 
+simultaneously. However, this could cause the BIOS to be starved out of the 
+lock - especially in cases such as the Embedded Controller driver where 
+there is a tight coupling between the OS and the BIOS.
+
+Implemented an optimization for the ACPI Global Lock interrupt mechanism. 
+The Global Lock interrupt handler no longer queues the execution of a 
+separate thread to signal the global lock semaphore. Instead, the semaphore 
+is signaled directly from the interrupt handler.
+
+Implemented support within the AML interpreter for package objects that 
+contain a larger AML length (package list length) than the package element 
+count. In this case, the length of the package is truncated to match the 
+package element count. Some BIOS code apparently modifies the package length 
+on the fly, and this change supports this behavior. Provides compatibility 
+with the MS AML interpreter. (With assistance from Fiodor Suietov)
+
+Implemented a temporary fix for the BankValue parameter of a Bank Field to 
+support all constant values, now including the Zero and One opcodes. 
+Evaluation of this parameter must eventually be converted to a full TermArg 
+evaluation. A not-implemented error is now returned (temporarily) for non-
+constant values for this parameter.
+
+Fixed problem reports (Fiodor Suietov) integrated:
+- Fix for premature object deletion after CopyObject on Operation Region (BZ 
+350)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+
+----------------------------------------
+07 July 2006. Summary of changes for version 20060707:
+
+1) ACPI CA Core Subsystem:
+
+Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers 
+that do not allow the initialization of address pointers within packed 
+structures - even though the hardware itself may support misaligned 
+transfers. Some of the debug data structures are packed by default to 
+minimize size.
+
+Added an error message for the case where AcpiOsGetThreadId() returns zero. 
+A non-zero value is required by the core ACPICA code to ensure the proper 
+operation of AML mutexes and recursive control methods.
+
+The DSDT is now the only ACPI table that determines whether the AML 
+interpreter is in 32-bit or 64-bit mode. Not really a functional change, but 
+the hooks for per-table 32/64 switching have been removed from the code. A 
+clarification to the ACPI specification is forthcoming in ACPI 3.0B.
+
+Fixed a possible leak of an OwnerID in the error path of 
+AcpiTbInitTableDescriptor (tbinstal.c), and migrated all table OwnerID 
+deletion to a single place in AcpiTbUninstallTable to correct possible leaks 
+when using the AcpiTbDeleteTablesByType interface (with assistance from 
+Lance Ortiz.)
+
+Fixed a problem with Serialized control methods where the semaphore 
+associated with the method could be over-signaled after multiple method 
+invocations.
+
+Fixed two issues with the locking of the internal namespace data structure. 
+Both the Unload() operator and AcpiUnloadTable interface now lock the 
+namespace during the namespace deletion associated with the table unload 
+(with assistance from Linn Crosetto.)
+
+Fixed problem reports (Valery Podrezov) integrated:
+- Eliminate unnecessary memory allocation for CreateXxxxField (BZ 5426)
+
+Fixed problem reports (Fiodor Suietov) integrated:
+- Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369)
+- On Address Space handler deletion, needless deactivation call (BZ 374)
+- AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 375)
+- Possible memory leak, Notify sub-objects of Processor, Power, ThermalZone 
+(BZ 376)
+- AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378)
+- Minimum Length of RSDT should be validated (BZ 379)
+- AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no 
+Handler (BZ (380)
+- AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type loaded 
+(BZ 381)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+436)
+
+----------------------------------------
+23 June 2006. Summary of changes for version 20060623:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This 
+allows the type to be customized to the host OS for improved efficiency 
+(since a spinlock is usually a very small object.)
+
+Implemented support for "ignored" bits in the ACPI registers. According to 
+the ACPI specification, these bits should be preserved when writing the 
+registers via a read/modify/write cycle. There are 3 bits preserved in this 
+manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11].
+
+Implemented the initial deployment of new OSL mutex interfaces. Since some 
+host operating systems have separate mutex and semaphore objects, this 
+feature was requested. The base code now uses mutexes (and the new mutex 
+interfaces) wherever a binary semaphore was used previously. However, for 
+the current release, the mutex interfaces are defined as macros to map them 
+to the existing semaphore interfaces. Therefore, no OSL changes are required 
+at this time. (See acpiosxf.h)
+
+Fixed several problems with the support for the control method SyncLevel 
+parameter. The SyncLevel now works according to the ACPI specification and 
+in concert with the Mutex SyncLevel parameter, since the current SyncLevel 
+is a property of the executing thread. Mutual exclusion for control methods 
+is now implemented with a mutex instead of a semaphore.
+
+Fixed three instances of the use of the C shift operator in the bitfield 
+support code (exfldio.c) to avoid the use of a shift value larger than the 
+target data width. The behavior of C compilers is undefined in this case and 
+can cause unpredictable results, and therefore the case must be detected and 
+avoided. (Fiodor Suietov)
+
+Added an info message whenever an SSDT or OEM table is loaded dynamically 
+via the Load() or LoadTable() ASL operators. This should improve debugging 
+capability since it will show exactly what tables have been loaded (beyond 
+the tables present in the RSDT/XSDT.)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.

+08 June 2006. Summary of changes for version 20060608:
+
+1) ACPI CA Core Subsystem:
+
+Converted the locking mutex used for the ACPI hardware to a spinlock. This 
+change should eliminate all problems caused by attempting to acquire a 
+semaphore at interrupt level, and it means that all ACPICA external 
+interfaces that directly access the ACPI hardware can be safely called from 
+interrupt level. OSL code that implements the semaphore interfaces should be 
+able to eliminate any workarounds for being called at interrupt level.
+
+Fixed a regression introduced in 20060526 where the ACPI device 
+initialization could be prematurely aborted with an AE_NOT_FOUND if a device 
+did not have an optional _INI method.
+
+Fixed an IndexField issue where a write to the Data Register should be 
+limited in size to the AccessSize (width) of the IndexField itself. (BZ 433, 
+Fiodor Suietov)
+
+Fixed problem reports (Valery Podrezov) integrated:
+- Allow store of ThermalZone objects to Debug object (BZ 5369/5370)
+
+Fixed problem reports (Fiodor Suietov) integrated:
+- AcpiGetTableHeader doesn't handle multiple instances correctly (BZ 364)
+
+Removed four global mutexes that were obsolete and were no longer being 
+used.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  80.0K Code, 17.7K Data,  97.7K Total
+    Debug Version:     160.3K Code, 64.9K Data, 225.2K Total
+  Current Release:
+    Non-Debug Version:  80.0K Code, 17.6K Data,  97.6K Total
+    Debug Version:     160.2K Code, 64.7K Data, 224.9K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a fault when using -g option (get tables from registry) on Windows 
+machines.
+
+Fixed problem reports integrated:
+- Generate error if CreateField NumBits parameter is zero. (BZ 405)
+- Fault if Offset/Length in Field unit is very large (BZ 432, Fiodor 
+Suietov)
+- Global table revision override (-r) is ignored (BZ 413)
+
+----------------------------------------
+26 May 2006. Summary of changes for version 20060526:
+
+1) ACPI CA Core Subsystem:
+
+Restructured, flattened, and simplified the internal interfaces for 
+namespace object evaluation - resulting in smaller code, less CPU stack use, 
+and fewer interfaces. (With assistance from Mikhail Kouzmich)
+
+Fixed a problem with the CopyObject operator where the first parameter was 
+not typed correctly for the parser, interpreter, compiler, and disassembler. 
+Caused various errors and unexpected behavior.
+
+Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits 
+produced incorrect results with some C compilers. Since the behavior of C 
+compilers when the shift value is larger than the datatype width is 
+apparently not well defined, the interpreter now detects this condition and 
+simply returns zero as expected in all such cases. (BZ 395)
+
+Fixed problem reports (Valery Podrezov) integrated:
+- Update String-to-Integer conversion to match ACPI 3.0A spec (BZ 5329)
+- Allow interpreter to handle nested method declarations (BZ 5361)
+
+Fixed problem reports (Fiodor Suietov) integrated:
+- AcpiTerminate doesn't free debug memory allocation list objects (BZ 355)
+- After Core Subsystem shutdown, AcpiSubsystemStatus returns AE_OK (BZ 356)
+- AcpiOsUnmapMemory for RSDP can be invoked inconsistently (BZ 357)
+- Resource Manager should return AE_TYPE for non-device objects (BZ 358)
+- Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359)
+- Use AcpiOsFree instead of ACPI_FREE in AcpiRsSetSrsMethodData (BZ 360)
+- Incomplete cleanup branch in AcpiPsParseAml (BZ 361)
+- Incomplete cleanup branch in AcpiDsDeleteWalkState (BZ 362)
+- AcpiGetTableHeader returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365)
+- Status of the Global Initialization Handler call not used (BZ 366)
+- Incorrect object parameter to Global Initialization Handler (BZ 367)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.8K Code, 17.7K Data,  97.5K Total
+    Debug Version:     160.5K Code, 65.1K Data, 225.6K Total
+  Current Release:
+    Non-Debug Version:  80.0K Code, 17.7K Data,  97.7K Total
+    Debug Version:     160.3K Code, 64.9K Data, 225.2K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Modified the parser to allow the names IO, DMA, and IRQ to be used as 
+namespace identifiers with no collision with existing resource descriptor 
+macro names. This provides compatibility with other ASL compilers and is 
+most useful for disassembly/recompilation of existing tables without parse 
+errors. (With assistance from Thomas Renninger)
+
+Disassembler: fixed an incorrect disassembly problem with the 
+DataTableRegion and CopyObject operators. Fixed a possible fault during 
+disassembly of some Alias operators.
+
+----------------------------------------
+12 May 2006. Summary of changes for version 20060512:
+
+1) ACPI CA Core Subsystem:
+
+Replaced the AcpiOsQueueForExecution interface with a new interface named 
+AcpiOsExecute. The major difference is that the new interface does not have 
+a Priority parameter, this appeared to be useless and has been replaced by a 
+Type parameter. The Type tells the host what type of execution is being 
+requested, such as global lock handler, notify handler, GPE handler, etc. 
+This allows the host to queue and execute the request as appropriate for the 
+request type, possibly using different work queues and different priorities 
+for the various request types. This enables fixes for multithreading 
+deadlock problems such as BZ #5534, and will require changes to all existing 
+OS interface layers. (Alexey Starikovskiy and Bob Moore)
+
+Fixed a possible memory leak associated with the support for the so-called 
+"implicit return" ACPI extension. Reported by FreeBSD, BZ #6514. (Fiodor 
+Suietov)
+
+Fixed a problem with the Load() operator where a table load from an 
+operation region could overwrite an internal table buffer by up to 7 bytes 
+and cause alignment faults on IPF systems. (With assistance from Luming Yu)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  79.7K Code, 17.7K Data,  97.4K Total
+    Debug Version:     160.1K Code, 65.2K Data, 225.3K Total
+  Current Release:
+    Non-Debug Version:  79.8K Code, 17.7K Data,  97.5K Total
+    Debug Version:     160.5K Code, 65.1K Data, 225.6K Total
+
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Implemented support to cross reference the internal namespace 
+and automatically generate ASL External() statements for symbols not defined 
+within the current table being disassembled. This will simplify the 
+disassembly and recompilation of interdependent tables such as SSDTs since 
+these statements will no longer have to be added manually.
+
+Disassembler: Implemented experimental support to automatically detect 
+invocations of external control methods and generate appropriate External() 
+statements. This is problematic because the AML cannot be correctly parsed 
+until the number of arguments for each control method is known. Currently, 
+standalone method invocations and invocations as the source operand of a 
+Store() statement are supported.
+
+Disassembler: Implemented support for the ASL pseudo-operators LNotEqual, 
+LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()), 
+LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code 
+more readable and likely closer to the original ASL source.
+
+----------------------------------------
+21 April 2006. Summary of changes for version 20060421:
+
+1) ACPI CA Core Subsystem:
+
+Removed a device initialization optimization introduced in 20051216 where 
+the _STA method was not run unless an _INI was also present for the same 
+device. This optimization could cause problems because it could allow _INI 
+methods to be run within a not-present device subtree. (If a not-present 
+device had no _INI, _STA would not be run, the not-present status would not 
+be discovered, and the children of the device would be incorrectly 
+traversed.)
+
+Implemented a new _STA optimization where namespace subtrees that do not 
+contain _INI are identified and ignored during device initialization. 
+Selectively running _STA can significantly improve boot time on large 
+machines (with assistance from Len Brown.)
+
+Implemented support for the device initialization case where the returned 
+_STA flags indicate a device not-present but functioning. In this case, _INI 
+is not run, but the device children are examined for presence, as per the 
+ACPI specification.
+
+Implemented an additional change to the IndexField support in order to 
+conform to MS behavior. The value written to the Index Register is not 
+simply a byte offset, it is a byte offset in units of the access width of 
+the parent Index Field. (Fiodor Suietov)
+
+Defined and deployed a new OSL interface, AcpiOsValidateAddress. This 
+interface is called during the creation of all AML operation regions, and 
+allows the host OS to exert control over what addresses it will allow the 
+AML code to access. Operation Regions whose addresses are disallowed will 
+cause a runtime exception when they are actually accessed (will not affect 
+or abort table loading.) See oswinxf or osunixxf for an example 
+implementation.
+
+Defined and deployed a new OSL interface, AcpiOsValidateInterface. This 
+interface allows the host OS to match the various "optional" 
+interface/behavior strings for the _OSI predefined control method as 
+appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf 
+for an example implementation.
+
+Restructured and corrected various problems in the exception handling code 
+paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod 
+(with assistance from Takayoshi Kochi.)
+
+Modified the Linux source converter to ignore quoted string literals while 
+converting identifiers from mixed to lower case. This will correct problems 
+with the disassembler and other areas where such strings must not be 
+modified.
+
+The ACPI_FUNCTION_* macros no longer require quotes around the function 
+name. This allows the Linux source converter to convert the names, now that 
+the converter ignores quoted strings.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+
+    Non-Debug Version:  81.1K Code, 17.7K Data,  98.8K Total
+    Debug Version:     158.9K Code, 64.9K Data, 223.8K Total
+  Current Release:
+    Non-Debug Version:  79.7K Code, 17.7K Data,  97.4K Total
+    Debug Version:     160.1K Code, 65.2K Data, 225.3K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Implemented 3 new warnings for iASL, and implemented multiple warning levels 
+(w2 flag).
+
+1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is not 
+WAIT_FOREVER (0xFFFF) and the code does not examine the return value to 
+check for the possible timeout, a warning is issued.
+
+2) Useless operators: If an ASL operator does not specify an optional target 
+operand and it also does not use the function return value from the 
+operator, a warning is issued since the operator effectively does nothing.
+
+3) Unreferenced objects: If a namespace object is created, but never 
+referenced, a warning is issued. This is a warning level 2 since there are 
+cases where this is ok, such as when a secondary table is loaded that uses 
+the unreferenced objects. Even so, care is taken to only flag objects that 
+don't look like they will ever be used. For example, the reserved methods 
+(starting with an underscore) are usually not referenced because it is 
+expected that the OS will invoke them.
+
+----------------------------------------
+31 March 2006. Summary of changes for version 20060331:
+
+1) ACPI CA Core Subsystem:
+
+Implemented header file support for the following additional ACPI tables: 
+ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, 
+all current and known ACPI tables are now defined in the ACPICA headers and 
+are available for use by device drivers and other software.
+
+Implemented support to allow tables that contain ACPI names with invalid 
+characters to be loaded. Previously, this would cause the table load to 
+fail, but since there are several known cases of such tables on existing 
+machines, this change was made to enable ACPI support for them. Also, this 
+matches the behavior of the Microsoft ACPI implementation.
+
+Fixed a couple regressions introduced during the memory optimization in the 
+20060317 release. The namespace node definition required additional 
+reorganization and an internal datatype that had been changed to 8-bit was 
+restored to 32-bit. (Valery Podrezov)
+
+Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState 
+could be passed through to AcpiOsReleaseObject which is unexpected. Such 
+null pointers are now trapped and ignored, matching the behavior of the 
+previous implementation before the deployment of AcpiOsReleaseObject.
+(Valery Podrezov, Fiodor Suietov)
+
+Fixed a memory mapping leak during the deletion of a SystemMemory operation 
+region where a cached memory mapping was not deleted. This became a 
+noticeable problem for operation regions that are defined within frequently 
+used control methods. (Dana Meyers)
+
+Reorganized the ACPI table header files into two main files: one for the 
+ACPI tables consumed by the ACPICA core, and another for the miscellaneous 
+ACPI tables that are consumed by the drivers and other software. The various 
+FADT definitions were merged into one common section and three different 
+tables (ACPI 1.0, 1.0+, and 2.0)
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and has 
+a much larger code and data size.
+
+  Previous Release:
+    Non-Debug Version:  80.9K Code, 17.7K Data,  98.6K Total
+    Debug Version:     158.7K Code, 64.8K Data, 223.5K Total
+  Current Release:
+    Non-Debug Version:  81.1K Code, 17.7K Data,  98.8K Total
+    Debug Version:     158.9K Code, 64.9K Data, 223.8K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Implemented support to decode and format all non-AML ACPI 
+tables (tables other than DSDTs and SSDTs.) This includes the new tables 
+added to the ACPICA headers, therefore all current and known ACPI tables are 
+supported.
+
+Disassembler: The change to allow ACPI names with invalid characters also 
+enables the disassembly of such tables. Invalid characters within names are 
+changed to '*' to make the name printable; the iASL compiler will still 
+generate an error for such names, however, since this is an invalid ACPI 
+character.
+
+Implemented an option for AcpiXtract (-a) to extract all tables found in the 
+input file. The default invocation extracts only the DSDTs and SSDTs.
+
+Fixed a couple of gcc generation issues for iASL and AcpiExec and added a 
+makefile for the AcpiXtract utility.
+
+----------------------------------------
+17 March 2006. Summary of changes for version 20060317:
+
+1) ACPI CA Core Subsystem:
+
+Implemented the use of a cache object for all internal namespace nodes. 
+Since there are about 1000 static nodes in a typical system, this will 
+decrease memory use for cache implementations that minimize per-allocation 
+overhead (such as a slab allocator.)
+
+Removed the reference count mechanism for internal namespace nodes, since it 
+was deemed unnecessary. This reduces the size of each namespace node by 
+about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, 
+and 32 bytes for the 64-bit case.
+
+Optimized several internal data structures to reduce object size on 64-bit 
+platforms by packing data within the 64-bit alignment. This includes the 
+frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static 
+instances corresponding to the namespace objects.
+
+Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" 
+and "Windows 2006".
+
+Split the allocation tracking mechanism out to a separate file, from 
+utalloc.c to uttrack.c. This mechanism appears to be only useful for 
+application-level code. Kernels may wish to not include uttrack.c in 
+distributions.
+
+Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated 
+code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING 
+macros.)
+
+Code and Data Size: These are the sizes for the acpica.lib produced by the 
+Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 
+driver or OSPM code. The debug version of the code includes the debug output 
+trace mechanism and has a much larger code and data size. Note that these 
+values will vary depending on the efficiency of the compiler and the 
+compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  81.1K Code, 17.8K Data,  98.9K Total
+    Debug Version:     161.6K Code, 65.7K Data, 227.3K Total
+  Current Release:
+    Non-Debug Version:  80.9K Code, 17.7K Data,  98.6K Total
+    Debug Version:     158.7K Code, 64.8K Data, 223.5K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Implemented an ANSI C version of the acpixtract utility. This version will 
+automatically extract the DSDT and all SSDTs from the input acpidump text 
+file and dump the binary output to separate files. It can also display a 
+summary of the input file including the headers for each table found and 
+will extract any single ACPI table, with any signature. (See 
+source/tools/acpixtract)
+
+----------------------------------------
+10 March 2006. Summary of changes for version 20060310:
+
+1) ACPI CA Core Subsystem:
+
+Tagged all external interfaces to the subsystem with the new 
+ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist 
+kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL 
+macro. The default definition is NULL.
+
+Added the ACPI_THREAD_ID type for the return value from AcpiOsGetThreadId. 
+This allows the host to define this as necessary to simplify kernel 
+integration. The default definition is ACPI_NATIVE_UINT.
+
+Fixed two interpreter problems related to error processing, the deletion of 
+objects, and placing invalid pointers onto the internal operator result 
+stack. BZ 6028, 6151 (Valery Podrezov)
+
+Increased the reference count threshold where a warning is emitted for large 
+reference counts in order to eliminate unnecessary warnings on systems with 
+large namespaces (especially 64-bit.) Increased the value from 0x400 to 
+0x800.
+
+Due to universal disagreement as to the meaning of the 'c' in the calloc() 
+function, the ACPI_MEM_CALLOCATE macro has been renamed to 
+ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. 
+ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and 
+ACPI_FREE.
+
+Code and Data Size: These are the sizes for the acpica.lib produced by the 
+Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 
+driver or OSPM code. The debug version of the code includes the debug output 
+trace mechanism and has a much larger code and data size. Note that these 
+values will vary depending on the efficiency of the compiler and the 
+compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  81.0K Code, 17.8K Data,  98.8K Total
+    Debug Version:     161.4K Code, 65.7K Data, 227.1K Total
+  Current Release:
+    Non-Debug Version:  81.1K Code, 17.8K Data,  98.9K Total
+    Debug Version:     161.6K Code, 65.7K Data, 227.3K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Disassembler: implemented support for symbolic resource descriptor 
+references. If a CreateXxxxField operator references a fixed offset within a 
+resource descriptor, a name is assigned to the descriptor and the offset is 
+translated to the appropriate resource tag and pathname. The addition of 
+this support brings the disassembled code very close to the original ASL 
+source code and helps eliminate run-time errors when the disassembled code 
+is modified (and recompiled) in such a way as to invalidate the original 
+fixed offsets.
+
+Implemented support for a Descriptor Name as the last parameter to the ASL 
+Register() macro. This parameter was inadvertently left out of the ACPI 
+specification, and will be added for ACPI 3.0b.
+
+Fixed a problem where the use of the "_OSI" string (versus the full path 
+"\_OSI") caused an internal compiler error. ("No back ptr to op")
+
+Fixed a problem with the error message that occurs when an invalid string is 
+used for a _HID object (such as one with an embedded asterisk: "*PNP010A".) 
+The correct message is now displayed.
+
+----------------------------------------
+17 February 2006. Summary of changes for version 20060217:
+
+1) ACPI CA Core Subsystem:
+
+Implemented a change to the IndexField support to match the behavior of the 
+Microsoft AML interpreter. The value written to the Index register is now a 
+byte offset, no longer an index based upon the width of the Data register. 
+This should fix IndexField problems seen on some machines where the Data 
+register is not exactly one byte wide. The ACPI specification will be 
+clarified on this point.
+
+Fixed a problem where several resource descriptor types could overrun the 
+internal descriptor buffer due to size miscalculation: VendorShort, 
+VendorLong, and Interrupt. This was noticed on IA64 machines, but could 
+affect all platforms.
+
+Fixed a problem where individual resource descriptors were misaligned within 
+the internal buffer, causing alignment faults on IA64 platforms.
+
+Code and Data Size: These are the sizes for the acpica.lib produced by the 
+Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 
+driver or OSPM code. The debug version of the code includes the debug output 
+trace mechanism and has a much larger code and data size. Note that these 
+values will vary depending on the efficiency of the compiler and the 
+compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  81.1K Code, 17.8K Data,  98.9K Total
+    Debug Version:     161.3K Code, 65.6K Data, 226.9K Total
+  Current Release:
+    Non-Debug Version:  81.0K Code, 17.8K Data,  98.8K Total
+    Debug Version:     161.4K Code, 65.7K Data, 227.1K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Implemented support for new reserved names: _WDG and _WED are Microsoft 
+extensions for Windows Instrumentation Management, _TDL is a new ACPI-
+defined method (Throttling Depth Limit.)
+
+Fixed a problem where a zero-length VendorShort or VendorLong resource 
+descriptor was incorrectly emitted as a descriptor of length one.
+
+----------------------------------------
+10 February 2006. Summary of changes for version 20060210:
+
+1) ACPI CA Core Subsystem:
+
+Removed a couple of extraneous ACPI_ERROR messages that appeared during 
+normal execution. These became apparent after the conversion from 
+ACPI_DEBUG_PRINT.
+
+Fixed a problem where the CreateField operator could hang if the BitIndex or 
+NumBits parameter referred to a named object. (Valery Podrezov, BZ 5359)
+
+Fixed a problem where a DeRefOf operation on a buffer object incorrectly 
+failed with an exception. This also fixes a couple of related RefOf and 
+DeRefOf issues. (Valery Podrezov, BZ 5360/5392/5387)
+
+Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of 
+AE_STRING_LIMIT on an out-of-bounds Index() operation. (Valery Podrezov, BZ 
+5480)
+
+Implemented a memory cleanup at the end of the execution of each iteration 
+of an AML While() loop, preventing the accumulation of outstanding objects. 
+(Valery Podrezov, BZ 5427)
+
+Eliminated a chunk of duplicate code in the object resolution code. (Valery 
+Podrezov, BZ 5336)
+
+Fixed several warnings during the 64-bit code generation.
+
+The AcpiSrc source code conversion tool now inserts one line of whitespace 
+after an if() statement that is followed immediately by a comment, improving 
+readability of the Linux code.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.

+expression for the BankValue parameter.

+27 January 2006. Summary of changes for version 20060127:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support in the Resource Manager to allow unresolved namestring 
+references within resource package objects for the _PRT method. This support 
+is in addition to the previously implemented unresolved reference support 
+within the AML parser. If the interpreter slack mode is enabled, these 
+unresolved references will be passed through to the caller as a NULL package 
+entry.
+
+Implemented and deployed new macros and functions for error and warning 
+messages across the subsystem. These macros are simpler and generate less 
+code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, 
+ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older 
+macros remain defined to allow ACPI drivers time to migrate to the new 
+macros.
+
+Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of the 
+Acquire/Release Lock OSL interfaces.
+
+Fixed a problem where Alias ASL operators are sometimes not correctly 
+resolved, in both the interpreter and the iASL compiler.
+
+Fixed several problems with the implementation of the ConcatenateResTemplate 
+ASL operator. As per the ACPI specification, zero length buffers are now 
+treated as a single EndTag. One-length buffers always cause a fatal 
+exception. Non-zero length buffers that do not end with a full 2-byte EndTag 
+cause a fatal exception.
+
+Fixed a possible structure overwrite in the AcpiGetObjectInfo external 
+interface. (With assistance from Thomas Renninger)
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  83.1K Code, 18.4K Data, 101.5K Total
+    Debug Version:     163.2K Code, 66.2K Data, 229.4K Total
+  Current Release:
+    Non-Debug Version:  81.0K Code, 17.9K Data,  98.9K Total
+    Debug Version:     161.3K Code, 65.7K Data, 227.0K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed an internal error that was generated for any forward references to ASL 
+Alias objects.
+
+----------------------------------------
+13 January 2006. Summary of changes for version 20060113:
+
+1) ACPI CA Core Subsystem:
+
+Added 2006 copyright to all module headers and signons. This affects 
+virtually every file in the ACPICA core subsystem, iASL compiler, and the 
+utilities.
+ 
+Enhanced the ACPICA error reporting in order to simplify user migration to 
+the non-debug version of ACPICA. Replaced all instances of the 
+ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug 
+levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, 
+respectively. This preserves all error and warning messages in the non-debug 
+version of the ACPICA code (this has been referred to as the "debug lite" 
+option.) Over 200 cases were converted to create a total of over 380 
+error/warning messages across the ACPICA code. This increases the code and 
+data size of the default non-debug version of the code somewhat (about 13K), 
+but all error/warning reporting may be disabled if desired (and code 
+eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time 
+configuration option. The size of the debug version of ACPICA remains about 
+the same.
+
+Fixed a memory leak within the AML Debugger "Set" command. One object was 
+not properly deleted for every successful invocation of the command.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  76.6K Code, 12.3K Data,  88.9K Total
+    Debug Version:     163.7K Code, 67.5K Data, 231.2K Total
+  Current Release:
+    Non-Debug Version:  83.1K Code, 18.4K Data, 101.5K Total
+    Debug Version:     163.2K Code, 66.2K Data, 229.4K Total
+
+
+2) iASL Compiler/Disassembler:
+
+The compiler now officially supports the ACPI 3.0a specification that was 
+released on December 30, 2005. (Specification is available at www.acpi.info)
+
+----------------------------------------
+16 December 2005. Summary of changes for version 20051216:
+
+1) ACPI CA Core Subsystem:
+
+Implemented optional support to allow unresolved names within ASL Package 
+objects. A null object is inserted in the package when a named reference 
+cannot be located in the current namespace. Enabled via the interpreter 
+slack flag, this should eliminate AE_NOT_FOUND exceptions seen on machines 
+that contain such code.
+
+Implemented an optimization to the initialization sequence that can improve 
+boot time. During ACPI device initialization, the _STA method is now run if 
+and only if the _INI method exists. The _STA method is used to determine if 
+the device is present; An _INI can only be run if _STA returns present, but 
+it is a waste of time to run the _STA method if the _INI does not exist. 
+(Prototype and assistance from Dong Wei)
+
+Implemented use of the C99 uintptr_t for the pointer casting macros if it is 
+available in the current compiler. Otherwise, the default (void *) cast is 
+used as before.
+
+Fixed some possible memory leaks found within the execution path of the 
+Break, Continue, If, and CreateField operators. (Valery Podrezov)
+
+Fixed a problem introduced in the 20051202 release where an exception is 
+generated during method execution if a control method attempts to declare 
+another method.
+
+Moved resource descriptor string constants that are used by both the AML 
+disassembler and AML debugger to the common utilities directory so that 
+these components are independent.
+
+Implemented support in the AcpiExec utility (-e switch) to globally ignore 
+exceptions during control method execution (method is not aborted.)
+
+Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix 
+generation.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  76.3K Code, 12.3K Data,  88.6K Total
+    Debug Version:     163.2K Code, 67.4K Data, 230.6K Total
+  Current Release:
+    Non-Debug Version:  76.6K Code, 12.3K Data,  88.9K Total
+    Debug Version:     163.7K Code, 67.5K Data, 231.2K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem where a CPU stack overflow fault could occur if a recursive 
+method call was made from within a Return statement.
+
+----------------------------------------
+02 December 2005. Summary of changes for version 20051202:
+
+1) ACPI CA Core Subsystem:
+
+Modified the parsing of control methods to no longer create namespace 
+objects during the first pass of the parse. Objects are now created only 
+during the execute phase, at the moment the namespace creation operator is 
+encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This 
+should eliminate ALREADY_EXISTS exceptions seen on some machines where 
+reentrant control methods are protected by an AML mutex. The mutex will now 
+correctly block multiple threads from attempting to create the same object 
+more than once.
+
+Increased the number of available Owner Ids for namespace object tracking 
+from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on 
+some machines with a large number of ACPI tables (either static or dynamic).
+
+Fixed a problem with the AcpiExec utility where a fault could occur when the 
+-b switch (batch mode) is used.
+
+Enhanced the namespace dump routine to output the owner ID for each 
+namespace object.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  76.3K Code, 12.3K Data,  88.6K Total
+    Debug Version:     163.0K Code, 67.4K Data, 230.4K Total
+  Current Release:
+    Non-Debug Version:  76.3K Code, 12.3K Data,  88.6K Total
+    Debug Version:     163.2K Code, 67.4K Data, 230.6K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a parse error during compilation of certain Switch/Case constructs. To 
+simplify the parse, the grammar now allows for multiple Default statements 
+and this error is now detected and flagged during the analysis phase.
+
+Disassembler: The disassembly now includes the contents of the original 
+table header within a comment at the start of the file. This includes the 
+name and version of the original ASL compiler.
+
+----------------------------------------
+17 November 2005. Summary of changes for version 20051117:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem in the AML parser where the method thread count could be 
+decremented below zero if any errors occurred during the method parse phase. 
+This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. 
+This also fixed a related regression with the mechanism that detects and 
+corrects methods that cannot properly handle reentrancy (related to the 
+deployment of the new OwnerId mechanism.)
+
+Eliminated the pre-parsing of control methods (to detect errors) during 
+table load. Related to the problem above, this was causing unwind issues if 
+any errors occurred during the parse, and it seemed to be overkill. A table 
+load should not be aborted if there are problems with any single control 
+method, thus rendering this feature rather pointless.
+
+Fixed a problem with the new table-driven resource manager where an internal 
+buffer overflow could occur for small resource templates.
+
+Implemented a new external interface, AcpiGetVendorResource. This interface 
+will find and return a vendor-defined resource descriptor within a _CRS or 
+_PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn Helgaas.
+
+Removed the length limit (200) on string objects as per the upcoming ACPI 
+3.0A specification. This affects the following areas of the interpreter: 1) 
+any implicit conversion of a Buffer to a String, 2) a String object result 
+of the ASL Concatentate operator, 3) the String object result of the ASL 
+ToString operator.
+
+Fixed a problem in the Windows OS interface layer (OSL) where a WAIT_FOREVER 
+on a semaphore object would incorrectly timeout. This allows the 
+multithreading features of the AcpiExec utility to work properly under 
+Windows.
+
+Updated the Linux makefiles for the iASL compiler and AcpiExec to include 
+the recently added file named "utresrc.c".
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  76.2K Code, 12.3K Data,  88.5K Total
+    Debug Version:     163.0K Code, 67.4K Data, 230.4K Total
+  Current Release:
+    Non-Debug Version:  76.3K Code, 12.3K Data,  88.6K Total
+    Debug Version:     163.0K Code, 67.4K Data, 230.4K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Removed the limit (200) on string objects as per the upcoming ACPI 3.0A 
+specification. For the iASL compiler, this means that string literals within 
+the source ASL can be of any length. 
+
+Enhanced the listing output to dump the AML code for resource descriptors 
+immediately after the ASL code for each descriptor, instead of in a block at 
+the end of the entire resource template.
+
+Enhanced the compiler debug output to dump the entire original parse tree 
+constructed during the parse phase, before any transforms are applied to the 
+tree. The transformed tree is dumped also.
+
+----------------------------------------
+02 November 2005. Summary of changes for version 20051102:
+
+1) ACPI CA Core Subsystem:
+
+Modified the subsystem initialization sequence to improve GPE support. The 
+GPE initialization has been split into two parts in order to defer execution 
+of the _PRW methods (Power Resources for Wake) until after the hardware is 
+fully initialized and the SCI handler is installed. This allows the _PRW 
+methods to access fields protected by the Global Lock. This will fix systems 
+where a NO_GLOBAL_LOCK exception has been seen during initialization.
+
+Converted the ACPI internal object disassemble and display code within the 
+AML debugger to fully table-driven operation, reducing code size and 
+increasing maintainability.
+
+Fixed a regression with the ConcatenateResTemplate() ASL operator introduced 
+in the 20051021 release.
+
+Implemented support for "local" internal ACPI object types within the 
+debugger "Object" command and the AcpiWalkNamespace external interfaces. 
+These local types include RegionFields, BankFields, IndexFields, Alias, and 
+reference objects.
+
+Moved common AML resource handling code into a new file, "utresrc.c". This 
+code is shared by both the Resource Manager and the AML Debugger.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  76.1K Code, 12.2K Data,  88.3K Total
+    Debug Version:     163.5K Code, 67.0K Data, 230.5K Total
+  Current Release:
+    Non-Debug Version:  76.2K Code, 12.3K Data,  88.5K Total
+    Debug Version:     163.0K Code, 67.4K Data, 230.4K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem with very large initializer lists (more than 4000 elements) 
+for both Buffer and Package objects where the parse stack could overflow.
+
+Enhanced the pre-compile source code scan for non-ASCII characters to ignore 
+characters within comment fields. The scan is now always performed and is no 
+longer optional, detecting invalid characters within a source file 
+immediately rather than during the parse phase or later.
+
+Enhanced the ASL grammar definition to force early reductions on all list-
+style grammar elements so that the overall parse stack usage is greatly 
+reduced. This should improve performance and reduce the possibility of parse 
+stack overflow.
+
+Eliminated all reduce/reduce conflicts in the iASL parser generation. Also, 
+with the addition of a %expected statement, the compiler generates from 
+source with no warnings.
+
+Fixed a possible segment fault in the disassembler if the input filename 
+does not contain a "dot" extension (Thomas Renninger).
+
+----------------------------------------
+21 October 2005. Summary of changes for version 20051021:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for the EM64T and other x86-64 processors. This 
+essentially entails recognizing that these processors support non-aligned 
+memory transfers. Previously, all 64-bit processors were assumed to lack 
+hardware support for non-aligned transfers.
+
+Completed conversion of the Resource Manager to nearly full table-driven 
+operation. Specifically, the resource conversion code (convert AML to 
+internal format and the reverse) and the debug code to dump internal 
+resource descriptors are fully table-driven, reducing code and data size and 
+improving maintainability.
+
+The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word 
+on 64-bit processors instead of a fixed 32-bit word. (With assistance from 
+Alexey Starikovskiy)
+
+Implemented support within the resource conversion code for the Type-
+Specific byte within the various ACPI 3.0 *WordSpace macros.
+
+Fixed some issues within the resource conversion code for the type-specific 
+flags for both Memory and I/O address resource descriptors. For Memory, 
+implemented support for the MTP and TTP flags. For I/O, split the TRS and 
+TTP flags into two separate fields.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  77.1K Code, 12.1K Data,  89.2K Total
+    Debug Version:     168.0K Code, 68.3K Data, 236.3K Total
+  Current Release:
+    Non-Debug Version:  76.1K Code, 12.2K Data,  88.3K Total
+    Debug Version:     163.5K Code, 67.0K Data, 230.5K Total
+
+
+
+2) iASL Compiler/Disassembler:
+
+Relaxed a compiler restriction that disallowed a ResourceIndex byte if the 
+corresponding ResourceSource string was not also present in a resource 
+descriptor declaration. This restriction caused problems with existing 
+AML/ASL code that includes the Index byte without the string. When such AML 
+was disassembled, it could not be compiled without modification. Further, 
+the modified code created a resource template with a different size than the 
+original, breaking code that used fixed offsets into the resource template 
+buffer.
+
+Removed a recent feature of the disassembler to ignore a lone ResourceIndex 
+byte. This byte is now emitted if present so that the exact AML can be 
+reproduced when the disassembled code is recompiled.
+
+Improved comments and text alignment for the resource descriptor code 
+emitted by the disassembler.
+
+Implemented disassembler support for the ACPI 3.0 AccessSize field within a 
+Register() resource descriptor.
+
+----------------------------------------
+30 September 2005. Summary of changes for version 20050930:
+
+1) ACPI CA Core Subsystem:
+
+Completed a major overhaul of the Resource Manager code - specifically, 
+optimizations in the area of the AML/internal resource conversion code. The 
+code has been optimized to simplify and eliminate duplicated code, CPU stack 
+use has been decreased by optimizing function parameters and local 
+variables, and naming conventions across the manager have been standardized 
+for clarity and ease of maintenance (this includes function, parameter, 
+variable, and struct/typedef names.) The update may force changes in some 
+driver code, depending on how resources are handled by the host OS.
+
+All Resource Manager dispatch and information tables have been moved to a 
+single location for clarity and ease of maintenance. One new file was 
+created, named "rsinfo.c".
+
+The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to 
+guarantee that the argument is not evaluated twice, making them less prone 
+to macro side-effects. However, since there exists the possibility of 
+additional stack use if a particular compiler cannot optimize them (such as 
+in the debug generation case), the original macros are optionally available.  
+Note that some invocations of the return_VALUE macro may now cause size 
+mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to 
+eliminate these. (From Randy Dunlap)
+
+Implemented a new mechanism to enable debug tracing for individual control 
+methods. A new external interface, AcpiDebugTrace, is provided to enable 
+this mechanism. The intent is to allow the host OS to easily enable and 
+disable tracing for problematic control methods. This interface can be 
+easily exposed to a user or debugger interface if desired. See the file 
+psxface.c for details.
+
+AcpiUtCallocate will now return a valid pointer if a length of zero is 
+specified - a length of one is used and a warning is issued. This matches 
+the behavior of AcpiUtAllocate.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  77.5K Code, 12.0K Data,  89.5K Total

+    Debug Version:     168.0K Code, 68.3K Data, 236.3K Total
+
+
+2) iASL Compiler/Disassembler:
+
+A remark is issued if the effective compile-time length of a package or 
+buffer is zero. Previously, this was a warning.
+
+----------------------------------------
+16 September 2005. Summary of changes for version 20050916:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem within the Resource Manager where support for the Generic 
+Register descriptor was not fully implemented. This descriptor is now fully 
+recognized, parsed, disassembled, and displayed.
+
+Completely restructured the Resource Manager code to utilize table-driven 
+dispatch and lookup, eliminating many of the large switch() statements. This 
+reduces overall subsystem code size and code complexity. Affects the 
+resource parsing and construction, disassembly, and debug dump output.
+
+Cleaned up and restructured the debug dump output for all resource 
+descriptors. Improved readability of the output and reduced code size.
+
+Fixed a problem where changes to internal data structures caused the 
+optional ACPI_MUTEX_DEBUG code to fail compilation if specified.
+
+Code and Data Size: The current and previous library sizes for the core 
+subsystem are shown below. These are the code and data sizes for the 
+acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 
+values do not include any ACPI driver or OSPM code. The debug version of the 
+code includes the debug output trace mechanism and has a much larger code 
+and data size. Note that these values will vary depending on the efficiency 
+of the compiler and the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  78.4K Code, 11.8K Data,  90.2K Total
+    Debug Version:     169.6K Code, 69.9K Data, 239.5K Total

+    Debug Version:     168.1K Code, 68.4K Data, 236.5K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Updated the disassembler to automatically insert an EndDependentFn() macro 
+into the ASL stream if this macro is missing in the original AML code, 
+simplifying compilation of the resulting ASL module.
+
+Fixed a problem in the disassembler where a disassembled ResourceSource 
+string (within a large resource descriptor) was not surrounded by quotes and 
+not followed by a comma, causing errors when the resulting ASL module was 
+compiled. Also, escape sequences within a ResourceSource string are now 
+handled correctly (especially "\\")
+
+----------------------------------------
+02 September 2005. Summary of changes for version 20050902:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem with the internal Owner ID allocation and deallocation 
+mechanisms for control method execution and recursive method invocation. 
+This should eliminate the OWNER_ID_LIMIT exceptions and "Invalid OwnerId" 
+messages seen on some systems. Recursive method invocation depth is 
+currently limited to 255. (Alexey Starikovskiy)
+
+Completely eliminated all vestiges of support for the "module-level 
+executable code" until this support is fully implemented and debugged. This 
+should eliminate the NO_RETURN_VALUE exceptions seen during table load on 
+some systems that invoke this support.
+
+Fixed a problem within the resource manager code where the transaction flags 
+for a 64-bit address descriptor were handled incorrectly in the type-
+specific flag byte.
+
+Consolidated duplicate code within the address descriptor resource manager 
+code, reducing overall subsystem code size.
+
+Fixed a fault when using the AML debugger "disassemble" command to 
+disassemble individual control methods.
+
+Removed references to the "release_current" directory within the Unix 
+release package.
+
+Code and Data Size: The current and previous core subsystem library sizes 
+are shown below. These are the code and data sizes for the acpica.lib 
+produced by the Microsoft Visual C++ 6.0 compiler. These values do not 
+include any ACPI driver or OSPM code. The debug version of the code includes 
+the debug output trace mechanism and has a much larger code and data size. 
+Note that these values will vary depending on the efficiency of the compiler 
+and the compiler options used during generation.

+2) iASL Compiler/Disassembler:
+
+Implemented an error check for illegal duplicate values in the interrupt and 
+dma lists for the following ASL macros: Dma(), Irq(), IrqNoFlags(), and 
+Interrupt().
+
+Implemented error checking for the Irq() and IrqNoFlags() macros to detect 
+too many values in the interrupt list (16 max) and invalid values in the 
+list (range 0 - 15)
+
+The maximum length string literal within an ASL file is now restricted to 
+200 characters as per the ACPI specification.
+
+Fixed a fault when using the -ln option (generate namespace listing).
+
+Implemented an error check to determine if a DescriptorName within a 
+resource descriptor has already been used within the current scope.
+
+----------------------------------------
+15 August 2005.  Summary of changes for version 20050815:
+ 
+1) ACPI CA Core Subsystem:
+ 
+Implemented a full bytewise compare to determine if a table load request is 
+attempting to load a duplicate table. The compare is performed if the table 
+signatures and table lengths match. This will allow different tables with 
+the same OEM Table ID and revision to be loaded - probably against the ACPI 
+specification, but discovered in the field nonetheless.
+ 
+Added the changes.txt logfile to each of the zipped release packages.
+ 
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+objects if optimization is disabled (via the -oa switch).
+

+length packages when the package length is not specified and the number of 
+initializer values is greater than 255.

+
+----------------------------------------
+29 July 2005.  Summary of changes for version 20050729:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support to ignore an attempt to install/load a particular ACPI 
+table more than once. Apparently there exists BIOS code that repeatedly 
+attempts to load the same SSDT upon certain events. With assistance from 
+Venkatesh Pallipadi.
+
+Restructured the main interface to the AML parser in order to correctly 
+handle all exceptional conditions. This will prevent leakage of the OwnerId 
+resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some 
+machines. With assistance from Alexey Starikovskiy.
+
+Support for "module level code" has been disabled in this version due to a 
+number of issues that have appeared on various machines. The support can be 
+enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem 
+compilation. When the issues are fully resolved, the code will be enabled by 
+default again.
+
+Modified the internal functions for debug print support to define the 
+FunctionName parameter as a (const char *) for compatibility with compiler 
+built-in macros such as __FUNCTION__, etc.
+
+Linted the entire ACPICA source tree for both 32-bit and 64-bit.
+
+Implemented support to display an object count summary for the AML Debugger 
+commands Object and Methods.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a regression that appeared in the 20050708 version of the compiler 
+where an error message was inadvertently emitted for invocations of the _OSI 
+reserved control method.
+
+----------------------------------------
+08 July 2005.  Summary of changes for version 20050708:
+
+1) ACPI CA Core Subsystem:
+
+The use of the CPU stack in the debug version of the subsystem has been 
+considerably reduced. Previously, a debug structure was declared in every 
+function that used the debug macros. This structure has been removed in 
+favor of declaring the individual elements as parameters to the debug 
+functions. This reduces the cumulative stack use during nested execution of 
+ACPI function calls at the cost of a small increase in the code size of the 
+debug version of the subsystem. With assistance from Alexey Starikovskiy and 
+Len Brown.
+
+Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent 
+headers to define a macro that will return the current function name at 
+runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by 
+the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the 
+compiler-dependent header, the function name is saved on the CPU stack (one 
+pointer per function.) This mechanism is used because apparently there 
+exists no standard ANSI-C defined macro that that returns the function name.
+
+Redesigned and reimplemented the "Owner ID" mechanism used to track 
+namespace objects created/deleted by ACPI tables and control method 
+execution. A bitmap is now used to allocate and free the IDs, thus solving 
+the wraparound problem present in the previous implementation. The size of 
+the namespace node descriptor was reduced by 2 bytes as a result (Alexey 
+Starikovskiy).
+
+Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield 
+flag definitions within the headers for the predefined ACPI tables. These 
+have been replaced by UINT8_BIT in order to increase the code portability of 
+the subsystem. If the use of UINT8 remains a problem, we may be forced to 
+eliminate bitfields entirely because of a lack of portability.
+
+Enhanced the performance of the AcpiUtUpdateObjectReference procedure. This 
+is a frequently used function and this improvement increases the performance 
+of the entire subsystem (Alexey Starikovskiy).
+
+Fixed several possible memory leaks and the inverse - premature object 
+deletion (Alexey Starikovskiy).
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+----------------------------------------
+24 June 2005.  Summary of changes for version 20050624:
+
+1) ACPI CA Core Subsystem:
+
+Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for 
+the host-defined cache object. This allows the OSL implementation to define 
+and type this object in any manner desired, simplifying the OSL 
+implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for 
+Linux, and should be defined in the OS-specific header file for other 
+operating systems as required.
+
+Changed the interface to AcpiOsAcquireObject to directly return the 
+requested object as the function return (instead of ACPI_STATUS.) This 
+change was made for performance reasons, since this is the purpose of the 
+interface in the first place. AcpiOsAcquireObject is now similar to the 
+AcpiOsAllocate interface.
+
+Implemented a new AML debugger command named Businfo. This command displays 
+information about all devices that have an associate _PRT object. The _ADR, 
+_HID, _UID, and _CID are displayed for these devices.
+
+Modified the initialization sequence in AcpiInitializeSubsystem to call the 
+OSL interface AcpiOslInitialize first, before any local initialization. This 
+change was required because the global initialization now calls OSL 
+interfaces.
+
+Enhanced the Dump command to display the entire contents of Package objects 
+(including all sub-objects and their values.) 
+
+Restructured the code base to split some files because of size and/or 
+because the code logically belonged in a separate file. New files are listed 
+below. All makefiles and project files included in the ACPI CA release have 
+been updated.
+    utilities/utcache.c           /* Local cache interfaces */
+    utilities/utmutex.c           /* Local mutex support */
+    utilities/utstate.c           /* State object support */
+    interpreter/parser/psloop.c   /* Main AML parse loop */
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a regression introduced in version 20050513 where the use of a Package 
+object within a Case() statement caused a compile time exception. The 
+original behavior has been restored (a Match() operator is emitted.)
+
+----------------------------------------
+17 June 2005.  Summary of changes for version 20050617:
+
+1) ACPI CA Core Subsystem:
+
+Moved the object cache operations into the OS interface layer (OSL) to allow 
+the host OS to handle these operations if desired (for example, the Linux 
+OSL will invoke the slab allocator). This support is optional; the compile 
+time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache 
+code in the ACPI CA core. The new OSL interfaces are shown below. See 
+utalloc.c for an example implementation, and acpiosxf.h for the exact 
+interface definitions. With assistance from Alexey Starikovskiy.
+    AcpiOsCreateCache
+    AcpiOsDeleteCache
+    AcpiOsPurgeCache
+    AcpiOsAcquireObject
+    AcpiOsReleaseObject
+
+Modified the interfaces to AcpiOsAcquireLock and AcpiOsReleaseLock to return 
+and restore a flags parameter. This fits better with many OS lock models. 
+Note: the current execution state (interrupt handler or not) is no longer 
+passed to these interfaces. If necessary, the OSL must determine this state 
+by itself, a simple and fast operation. With assistance from Alexey 
+Starikovskiy.
+
+Fixed a problem in the ACPI table handling where a valid XSDT was assumed 
+present if the revision of the RSDP was 2 or greater. According to the ACPI 
+specification, the XSDT is optional in all cases, and the table manager 
+therefore now checks for both an RSDP >=2 and a valid XSDT pointer. 
+Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain 
+only the RSDT.
+
+Fixed an interpreter problem with the Mid() operator in the case of an input 
+string where the resulting output string is of zero length. It now correctly 
+returns a valid, null terminated string object instead of a string object 
+with a null pointer.
+
+Fixed a problem with the control method argument handling to allow a store 
+to an Arg object that already contains an object of type Device. The Device 
+object is now correctly overwritten. Previously, an error was returned.
+
+
+Enhanced the debugger Find command to emit object values in addition to the 
+found object pathnames. The output format is the same as the dump namespace 
+command.
+
+Enhanced the debugger Set command. It now has the ability to set the value 
+of any Named integer object in the namespace (Previously, only method locals 
+and args could be set.)
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Debug Version:     164.0K Code, 69.1K Data, 233.1K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a regression in the disassembler where if/else/while constructs were 
+output incorrectly. This problem was introduced in the previous release 
+(20050526). This problem also affected the single-step disassembly in the 
+debugger.
+
+Fixed a problem where compiling the reserved _OSI method would randomly (but 
+rarely) produce compile errors.
+
+Enhanced the disassembler to emit compilable code in the face of incorrect 
+AML resource descriptors. If the optional ResourceSourceIndex is present, 
+but the ResourceSource is not, do not emit the ResourceSourceIndex in the 
+disassembly. Otherwise, the resulting code cannot be compiled without 
+errors.
+
+----------------------------------------
+26 May 2005.  Summary of changes for version 20050526:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support to execute Type 1 and Type 2 AML opcodes appearing at 
+the module level (not within a control method.) These opcodes are executed 
+exactly once at the time the table is loaded. This type of code was legal up 
+until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in 
+order to provide backwards compatibility with earlier BIOS implementations. 
+This eliminates the "Encountered executable code at module level" warning 
+that was previously generated upon detection of such code.
+
+Fixed a problem in the interpreter where an AE_NOT_FOUND exception could 
+inadvertently be generated during the lookup of namespace objects in the 
+second pass parse of ACPI tables and control methods. It appears that this 
+problem could occur during the resolution of forward references to namespace 
+objects.
+
+Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function, 
+corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This 
+allows the deadlock detection debug code to be compiled out in the normal 
+case, improving mutex performance (and overall subsystem performance) 
+considerably.
+
+Implemented a handful of miscellaneous fixes for possible memory leaks on 
+error conditions and error handling control paths. These fixes were 
+suggested by FreeBSD and the Coverity Prevent source code analysis tool.
+
+Added a check for a null RSDT pointer in AcpiGetFirmwareTable (tbxfroot.c) 
+to prevent a fault in this error case.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Debug Version:     164.0K Code, 69.3K Data, 233.3K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Implemented support to allow Type 1 and Type 2 ASL operators to appear at 
+the module level (not within a control method.) These operators will be 
+executed once at the time the table is loaded. This type of code was legal 
+up until the release of ACPI 2.0B (2002) and is now supported by the iASL 
+compiler in order to provide backwards compatibility with earlier BIOS ASL 
+code.
+
+The ACPI integer width (specified via the table revision ID or the -r 
+override, 32 or 64 bits) is now used internally during compile-time constant 
+folding to ensure that constants are truncated to 32 bits if necessary. 
+Previously, the revision ID value was only emitted in the AML table header.
+
+An error message is now generated for the Mutex and Method operators if the 
+SyncLevel parameter is outside the legal range of 0 through 15.
+
+Fixed a problem with the Method operator ParameterTypes list handling (ACPI 
+3.0). Previously, more than 2 types or 2 arguments generated a syntax error.  
+The actual underlying implementation of method argument typechecking is 
+still under development, however.
+
+----------------------------------------
+13 May 2005.  Summary of changes for version 20050513:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for PCI Express root bridges -- added support for device 
+PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup.
+
+The interpreter now automatically truncates incoming 64-bit constants to 32 
+bits if currently executing out of a 32-bit ACPI table (Revision < 2). This 
+also affects the iASL compiler constant folding. (Note: as per below, the 
+iASL compiler no longer allows 64-bit constants within 32-bit tables.)
+
+Fixed a problem where string and buffer objects with "static" pointers 
+(pointers to initialization data within an ACPI table) were not handled 
+consistently. The internal object copy operation now always copies the data 
+to a newly allocated buffer, regardless of whether the source object is 
+static or not.
+
+Fixed a problem with the FromBCD operator where an implicit result 
+conversion was improperly performed while storing the result to the target 
+operand. Since this is an "explicit conversion" operator, the implicit 
+conversion should never be performed on the output.
+
+Fixed a problem with the CopyObject operator where a copy to an existing 
+named object did not always completely overwrite the existing object stored 
+at name. Specifically, a buffer-to-buffer copy did not delete the existing 
+buffer.
+
+Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces and 
+structs for consistency.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Debug Version:     163.7K Code, 69.3K Data, 233.0K Total
+
+
+2) iASL Compiler/Disassembler:
+
+The compiler now emits a warning if an attempt is made to generate a 64-bit 
+integer constant from within a 32-bit ACPI table (Revision < 2). The integer 
+is truncated to 32 bits.
+
+Fixed a problem with large package objects: if the static length of the 
+package is greater than 255, the "variable length package" opcode is 
+emitted. Previously, this caused an error. This requires an update to the 
+ACPI spec, since it currently (incorrectly) states that packages larger than 
+255 elements are not allowed.
+
+The disassembler now correctly handles variable length packages and packages 
+larger than 255 elements.
+
+----------------------------------------
+08 April 2005.  Summary of changes for version 20050408:
+
+1) ACPI CA Core Subsystem:
+
+Fixed three cases in the interpreter where an "index" argument to an ASL 
+function was still (internally) 32 bits instead of the required 64 bits. 
+This was the Index argument to the Index, Mid, and Match operators.
+
+The "strupr" function is now permanently local (AcpiUtStrupr), since this is 
+not a POSIX-defined function and not present in most kernel-level C 
+libraries. All references to the C library strupr function have been removed 
+from the headers.
+
+Completed the deployment of static functions/prototypes. All prototypes with 
+the static attribute have been moved from the headers to the owning C file.
+
+Implemented an extract option (-e) for the AcpiBin utility (AML binary 
+utility). This option allows the utility to extract individual ACPI tables 
+from the output of AcpiDmp. It provides the same functionality of the 
+acpixtract.pl perl script without the worry of setting the correct perl 
+options. AcpiBin runs on Windows and has not yet been generated/validated in 
+the Linux/Unix environment (but should be soon).
+ 
+Updated and fixed the table dump option for AcpiBin (-d). This option 
+converts a single ACPI table to a hex/ascii file, similar to the output of 
+AcpiDmp.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Disassembler fix: Added a check to ensure that the table length found in the 
+ACPI table header within the input file is not longer than the actual input 
+file size. This indicates some kind of file or table corruption.
+
+----------------------------------------
+29 March 2005.  Summary of changes for version 20050329:
+
+1) ACPI CA Core Subsystem:
+
+An error is now generated if an attempt is made to create a Buffer Field of 
+length zero (A CreateField with a length operand of zero.)
+
+The interpreter now issues a warning whenever executable code at the module 
+level is detected during ACPI table load. This will give some idea of the 
+prevalence of this type of code.
+
+Implemented support for references to named objects (other than control 
+methods) within package objects.
+
+Enhanced package object output for the debug object. Package objects are now 
+completely dumped, showing all elements.
+
+Enhanced miscellaneous object output for the debug object. Any object can 
+now be written to the debug object (for example, a device object can be 
+written, and the type of the object will be displayed.)
+
+The "static" qualifier has been added to all local functions across both the 
+core subsystem and the iASL compiler.
+
+The number of "long" lines (> 80 chars) within the source has been 
+significantly reduced, by about 1/3.
+
+Cleaned up all header files to ensure that all CA/iASL functions are 
+prototyped (even static functions) and the formatting is consistent.
+
+Two new header files have been added, acopcode.h and acnames.h.
+
+Removed several obsolete functions that were no longer used.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+ResourceSourceIndex and the ResourceSource fields, both must be present, or 
+both must be not present - can't have one without the other.
+
+The compiler now returns non-zero from the main procedure if any errors have 
+occurred during the compilation.
+
+
+----------------------------------------
+09 March 2005.  Summary of changes for version 20050309:
+
+1) ACPI CA Core Subsystem:
+
+The string-to-buffer implicit conversion code has been modified again after 
+a change to the ACPI specification.  In order to match the behavior of the 
+other major ACPI implementation, the target buffer is no longer truncated if 
+the source string is smaller than an existing target buffer. This change 
+requires an update to the ACPI spec, and should eliminate the recent 
+AE_AML_BUFFER_LIMIT issues.
+
+The "implicit return" support was rewritten to a new algorithm that solves 
+the general case. Rather than attempt to determine when a method is about to 
+exit, the result of every ASL operator is saved momentarily until the very 
+next ASL operator is executed. Therefore, no matter how the method exits, 
+there will always be a saved implicit return value. This feature is only 
+enabled with the AcpiGbl_EnableInterpreterSlack flag, and should eliminate 
+AE_AML_NO_RETURN_VALUE errors when enabled.
+
+Implemented implicit conversion support for the predicate (operand) of the 
+If, Else, and While operators. String and Buffer arguments are automatically 
+converted to Integers.
+
+Changed the string-to-integer conversion behavior to match the new ACPI 
+errata: "If no integer object exists, a new integer is created. The ASCII 
+string is interpreted as a hexadecimal constant. Each string character is 
+interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting 
+with the first character as the most significant digit, and ending with the 
+first non-hexadecimal character or end-of-string." This means that the first 
+non-hex character terminates the conversion and this is the code that was 
+changed.
+
+Fixed a problem where the ObjectType operator would fail (fault) when used 
+on an Index of a Package which pointed to a null package element. The 
+operator now properly returns zero (Uninitialized) in this case.
+
+Fixed a problem where the While operator used excessive memory by not 
+properly popping the result stack during execution. There was no memory leak 
+after execution, however. (Code provided by Valery Podrezov.)
+
+Fixed a problem where references to control methods within Package objects 
+caused the method to be invoked, instead of producing a reference object 
+pointing to the method.
+
+Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) to 
+improve performance and reduce code size. (Code provided by Alexey 
+Starikovskiy.)
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  78.3K Code, 11.5K Data,  89.8K Total
+    Debug Version:     165.4K Code, 69.6K Data, 236.0K Total

+    Debug Version:     165.4K Code, 69.7K Data, 236.1K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem with the Return operator with no arguments. Since the AML 
+grammar for the byte encoding requires an operand for the Return opcode, the 
+compiler now emits a Return(Zero) for this case.  An ACPI specification 
+update has been written for this case.
+
+For tables other than the DSDT, namepath optimization is automatically 
+disabled. This is because SSDTs can be loaded anywhere in the namespace, the 
+compiler has no knowledge of where, and thus cannot optimize namepaths.
+
+Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was 
+inadvertently omitted from the ACPI specification, and will require an 
+update to the spec.
+
+The source file scan for ASCII characters is now optional (-a). This change 
+was made because some vendors place non-ascii characters within comments. 
+However, the scan is simply a brute-force byte compare to ensure all 
+characters in the file are in the range 0x00 to 0x7F.
+
+Fixed a problem with the CondRefOf operator where the compiler was 
+inappropriately checking for the existence of the target. Since the point of 
+the operator is to check for the existence of the target at run-time, the 
+compiler no longer checks for the target existence.
+
+Fixed a problem where errors generated from the internal AML interpreter 
+during constant folding were not handled properly, causing a fault.
+
+Fixed a problem with overly aggressive range checking for the Stall 
+operator. The valid range (max 255) is now only checked if the operand is of 
+type Integer. All other operand types cannot be statically checked.
+
+Fixed a problem where control method references within the RefOf, DeRefOf, 
+and ObjectType operators were not treated properly. They are now treated as 
+actual references, not method invocations.
+
+Fixed and enhanced the "list namespace" option (-ln). This option was broken 
+a number of releases ago.
+
+Improved error handling for the Field, IndexField, and BankField operators. 
+The compiler now cleanly reports and recovers from errors in the field 
+component (FieldUnit) list.
+
+Fixed a disassembler problem where the optional ResourceDescriptor fields 
+TRS and TTP were not always handled correctly.
+
+Disassembler - Comments in output now use "//" instead of "/*"
+
+----------------------------------------
+28 February 2005.  Summary of changes for version 20050228:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where the result of an Index() operator (an object 
+reference) must increment the reference count on the target object for the 
+life of the object reference.
+
+Implemented AML Interpreter and Debugger support for the new ACPI 3.0 
+Extended Address (IO, Memory, Space), QwordSpace, DwordSpace, and WordSpace 
+resource descriptors.
+
+Implemented support in the _OSI method for the ACPI 3.0 "Extended Address 
+Space Descriptor" string, indicating interpreter support for the descriptors 
+above.
+
+Implemented header support for the new ACPI 3.0 FADT flag bits.
+
+Implemented header support for the new ACPI 3.0 PCI Express bits for the PM1 
+status/enable registers.
+
+Updated header support for the MADT processor local Apic struct and MADT 
+platform interrupt source struct for new ACPI 3.0 fields.
+
+Implemented header support for the SRAT and SLIT ACPI tables.
+
+Implemented the -s switch in AcpiExec to enable the "InterpreterSlack" flag 
+at runtime.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  78.2K Code, 11.5K Data,  89.7K Total
+    Debug Version:     164.9K Code, 69.2K Data, 234.1K Total

+    Non-Debug Version:  78.3K Code, 11.5K Data,  89.8K Total
+    Debug Version:     165.4K Code, 69.6K Data, 236.0K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem with the internal 64-bit String-to-integer conversion with 
+strings less than two characters long.
+
+Fixed a problem with constant folding where the result of the Index() 
+operator can not be considered a constant. This means that Index() cannot be 
+a type3 opcode and this will require an update to the ACPI specification.
+
+Disassembler: Implemented support for the TTP, MTP, and TRS resource 
+descriptor fields. These fields were inadvertently ignored and not output in 
+the disassembly of the resource descriptor.
+
+
+ ----------------------------------------
+11 February 2005.  Summary of changes for version 20050211:
+
+1) ACPI CA Core Subsystem:
+
+Implemented ACPI 3.0 support for implicit conversion within the Match() 
+operator. MatchObjects can now be of type integer, buffer, or string instead 
+of just type integer.  Package elements are implicitly converted to the type 
+of the MatchObject. This change aligns the behavior of Match() with the 
+behavior of the other logical operators (LLess(), etc.) It also requires an 
+errata change to the ACPI specification as this support was intended for 
+ACPI 3.0, but was inadvertently omitted.
+
+Fixed a problem with the internal implicit "to buffer" conversion. Strings 
+that are converted to buffers will cause buffer truncation if the string is 
+smaller than the target buffer. Integers that are converted to buffers will 
+not cause buffer truncation, only zero extension (both as per the ACPI 
+spec.) The problem was introduced when code was added to truncate the 
+buffer, but this should not be performed in all cases, only the string case.
+
+Fixed a problem with the Buffer and Package operators where the interpreter 
+would get confused if two such operators were used as operands to an ASL 
+operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result 
+stack was not being popped after the execution of these operators, resulting 
+in an AE_NO_RETURN_VALUE exception.
+
+Fixed a problem with constructs of the form Store(Index(...),...). The 
+reference object returned from Index was inadvertently resolved to an actual 
+value. This problem was introduced in version 20050114 when the behavior of 
+Store() was modified to restrict the object types that can be used as the 
+source operand (to match the ACPI specification.)
+
+Reduced excessive stack use within the AcpiGetObjectInfo procedure.
+
+Added a fix to aclinux.h to allow generation of AcpiExec on Linux.
+
+Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Non-Debug Version:  78.1K Code, 11.5K Data,  89.6K Total
+    Debug Version:     164.8K Code, 69.2K Data, 234.0K Total

+    Debug Version:     164.9K Code, 69.2K Data, 234.1K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a code generation problem in the constant folding optimization code 
+where incorrect code was generated if a constant was reduced to a buffer 
+object (i.e., a reduced type 5 opcode.)
+
+Fixed a typechecking problem for the ToBuffer operator. Caused by an 
+incorrect return type in the internal opcode information table.
+
+----------------------------------------
+25 January 2005.  Summary of changes for version 20050125:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a recently introduced problem with the Global Lock where the 
+underlying semaphore was not created.  This problem was introduced in 
+version 20050114, and caused an AE_AML_NO_OPERAND exception during an 
+Acquire() operation on _GL.
+
+The local object cache is now optional, and is disabled by default. Both 
+AcpiExec and the iASL compiler enable the cache because they run in user 
+mode and this enhances their performance. #define ACPI_ENABLE_OBJECT_CACHE 
+to enable the local cache.
+
+Fixed an issue in the internal function AcpiUtEvaluateObject concerning the 
+optional "implicit return" support where an error was returned if no return 
+object was expected, but one was implicitly returned. AE_OK is now returned 
+in this case and the implicitly returned object is deleted. 
+AcpiUtEvaluateObject is only occasionally used, and only to execute reserved 
+methods such as _STA and _INI where the return type is known up front.
+
+Fixed a few issues with the internal convert-to-integer code. It now returns 
+an error if an attempt is made to convert a null string, a string of only 
+blanks/tabs, or a zero-length buffer. This affects both implicit conversion 
+and explicit conversion via the ToInteger() operator.
+
+The internal debug code in AcpiUtAcquireMutex has been commented out. It is 
+not needed for normal operation and should increase the performance of the 
+entire subsystem. The code remains in case it is needed for debug purposes 
+again.
+
+The AcpiExec source and makefile are included in the Unix/Linux package for 
+the first time.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  78.4K Code,  11.5K Data,   89.9K Total
+    Debug Version:     165.4K Code,  69.4K Data,  234.8K Total
+  Current Release:
+    Non-Debug Version:  78.1K Code,  11.5K Data,   89.6K Total
+    Debug Version:     164.8K Code,  69.2K Data,  234.0K Total
+
+2) iASL Compiler/Disassembler:
+
+Switch/Case support: A warning is now issued if the type of the Switch value 
+cannot be determined at compile time. For example, Switch(Arg0) will 
+generate the warning, and the type is assumed to be an integer. As per the 
+ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate the 
+warning.
+
+Switch/Case support: Implemented support for buffer and string objects as 
+the switch value.  This is an ACPI 3.0 feature, now that LEqual supports 
+buffers and strings.
+
+Switch/Case support: The emitted code for the LEqual() comparisons now uses 
+the switch value as the first operand, not the second. The case value is now 
+the second operand, and this allows the case value to be implicitly 
+converted to the type of the switch value, not the other way around.
+
+Switch/Case support: Temporary variables are now emitted immediately within 
+the control method, not at the global level. This means that there are now 
+36 temps available per-method, not 36 temps per-module as was the case with 
+the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.)
+
+----------------------------------------
+14 January 2005.  Summary of changes for version 20050114:
+
+Added 2005 copyright to all module headers.  This affects every module in 
+the core subsystem, iASL compiler, and the utilities.
+
+1) ACPI CA Core Subsystem:
+
+Fixed an issue with the String-to-Buffer conversion code where the string 
+null terminator was not included in the buffer after conversion, but there 
+is existing ASL that assumes the string null terminator is included. This is 
+the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was 
+introduced in the previous version when the code was updated to correctly 
+set the converted buffer size as per the ACPI specification. The ACPI spec 
+is ambiguous and will be updated to specify that the null terminator must be 
+included in the converted buffer. This also affects the ToBuffer() ASL 
+operator.
+
+Fixed a problem with the Mid() ASL/AML operator where it did not work 
+correctly on Buffer objects. Newly created sub-buffers were not being marked 
+as initialized.
+
+
+Fixed a problem in AcpiTbFindTable where incorrect string compares were 
+performed on the OemId and OemTableId table header fields.  These fields are 
+not null terminated, so strncmp is now used instead of strcmp.
+
+Implemented a restriction on the Store() ASL/AML operator to align the 
+behavior with the ACPI specification.  Previously, any object could be used 
+as the source operand.  Now, the only objects that may be used are Integers, 
+Buffers, Strings, Packages, Object References, and DDB Handles.  If 
+necessary, the original behavior can be restored by enabling the 
+EnableInterpreterSlack flag.
+
+Enhanced the optional "implicit return" support to allow an implicit return 
+value from methods that are invoked externally via the AcpiEvaluateObject 
+interface.  This enables implicit returns from the _STA and _INI methods, 
+for example.
+
+Changed the Revision() ASL/AML operator to return the current version of the 
+AML interpreter, in the YYYYMMDD format. Previously, it incorrectly returned 
+the supported ACPI version (This is the function of the _REV method).
+
+Updated the _REV predefined method to return the currently supported version 
+of ACPI, now 3.
+
+Implemented batch mode option for the AcpiExec utility (-b).
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+----------------------------------------
+10 December 2004.  Summary of changes for version 20041210:
+
+ACPI 3.0 support is nearing completion in both the iASL compiler and the 
+ACPI CA core subsystem.
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem in the ToDecimalString operator where the resulting string 
+length was incorrectly calculated. The length is now calculated exactly, 
+eliminating incorrect AE_STRING_LIMIT exceptions.
+
+Fixed a problem in the ToHexString operator to allow a maximum 200 character 
+string to be produced.
+
+Fixed a problem in the internal string-to-buffer and buffer-to-buffer copy 
+routine where the length of the resulting buffer was not truncated to the 
+new size (if the target buffer already existed).
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the

+that these values will vary depending on the efficiency of the compiler and

+    Debug Version:     165.3K Code,  69.4K Data,  234.7K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Implemented the new ACPI 3.0 resource template macros - DWordSpace, 
+ExtendedIO, ExtendedMemory, ExtendedSpace, QWordSpace, and WordSpace. 
+Includes support in the disassembler.
+
+Implemented support for the new (ACPI 3.0) parameter to the Register macro, 
+AccessSize.
+
+Fixed a problem where the _HE resource name for the Interrupt macro was 
+referencing bit 0 instead of bit 1.
+
+Implemented check for maximum 255 interrupts in the Interrupt macro.
+
+Fixed a problem with the predefined resource descriptor names where 
+incorrect AML code was generated if the offset within the resource buffer 
+was 0 or 1.  The optimizer shortened the AML code to a single byte opcode 
+but did not update the surrounding package lengths.
+
+Changes to the Dma macro:  All channels within the channel list must be in 
+the range 0-7.  Maximum 8 channels can be specified. BusMaster operand is 
+optional (default is BusMaster).
+
+Implemented check for maximum 7 data bytes for the VendorShort macro.
+
+The ReadWrite parameter is now optional for the Memory32 and similar macros.
+
+----------------------------------------
+03 December 2004.  Summary of changes for version 20041203:
+
+1) ACPI CA Core Subsystem:
+
+The low-level field insertion/extraction code (exfldio) has been completely 
+rewritten to eliminate unnecessary complexity, bugs, and boundary 
+conditions.
+
+Fixed a problem in the ToInteger, ToBuffer, ToHexString, and ToDecimalString 
+operators where the input operand could be inadvertently deleted if no 
+conversion was necessary (e.g., if the input to ToInteger was an Integer 
+object.)
+
+Fixed a problem with the ToDecimalString and ToHexString where an incorrect 
+exception code was returned if the resulting string would be > 200 chars.  
+AE_STRING_LIMIT is now returned.
+
+Fixed a problem with the Concatenate operator where AE_OK was always 
+returned, even if the operation failed.
+
+Fixed a problem in oswinxf (used by AcpiExec and iASL) to allow > 128 
+semaphores to be allocated.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the

+
+
+2) iASL Compiler/Disassembler:
+
+Fixed typechecking for the ObjectType and SizeOf operators.  Problem was 
+recently introduced in 20041119.
+
+Fixed a problem with the ToUUID macro where the upper nybble of each buffer 
+byte was inadvertently set to zero.
+
+----------------------------------------
+19 November 2004.  Summary of changes for version 20041119:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem in the internal ConvertToInteger routine where new integers 
+were not truncated to 32 bits for 32-bit ACPI tables. This routine converts 
+buffers and strings to integers.
+
+Implemented support to store a value to an Index() on a String object. This 
+is an ACPI 2.0 feature that had not yet been implemented.
+
+Implemented new behavior for storing objects to individual package elements 
+(via the Index() operator). The previous behavior was to invoke the implicit 
+conversion rules if an object was already present at the index.  The new 
+behavior is to simply delete any existing object and directly store the new 
+object. Although the ACPI specification seems unclear on this subject, other 
+ACPI implementations behave in this manner.  (This is the root of the 
+AE_BAD_HEX_CONSTANT issue.)
+
+Modified the RSDP memory scan mechanism to support the extended checksum for 
+ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid 
+RSDP signature is found with a valid checksum.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a missing semicolon in the aslcompiler.y file.
+
+----------------------------------------
+05 November 2004.  Summary of changes for version 20041105:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for FADT revision 2.  This was an interim table (between 
+ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register.
+
+Implemented optional support to allow uninitialized LocalX and ArgX 
+variables in a control method.  The variables are initialized to an Integer 
+object with a value of zero.  This support is enabled by setting the 
+AcpiGbl_EnableInterpreterSlack flag to TRUE.
+
+Implemented support for Integer objects for the SizeOf operator.  Either 4 
+or 8 is returned, depending on the current integer size (32-bit or 64-bit, 
+depending on the parent table revision).
+
+Fixed a problem in the implementation of the SizeOf and ObjectType operators 
+where the operand was resolved to a value too early, causing incorrect 
+return values for some objects.
+
+Fixed some possible memory leaks during exceptional conditions.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the

+----------------------------------------
+15 October 2004.  Summary of changes for version 20041015:
+
+Note:  ACPI CA is currently undergoing an in-depth and complete formal 
+evaluation to test/verify the following areas. Other suggestions are 
+welcome. This will result in an increase in the frequency of releases and 
+the number of bug fixes in the next few months.
+  - Functional tests for all ASL/AML operators
+  - All implicit/explicit type conversions
+  - Bit fields and operation regions
+  - 64-bit math support and 32-bit-only "truncated" math support
+  - Exceptional conditions, both compiler and interpreter
+  - Dynamic object deletion and memory leaks
+  - ACPI 3.0 support when implemented
+  - External interfaces to the ACPI subsystem
+
+
+1) ACPI CA Core Subsystem:
+
+Fixed two alignment issues on 64-bit platforms - within debug statements in 
+AcpiEvGpeDetect and AcpiEvCreateGpeBlock. Removed references to the Address 
+field within the non-aligned ACPI generic address structure.
+
+Fixed a problem in the Increment and Decrement operators where incorrect 
+operand resolution could result in the inadvertent modification of the 
+original integer when the integer is passed into another method as an 
+argument and the arg is then incremented/decremented.
+
+Fixed a problem in the FromBCD operator where the upper 32-bits of a 64-bit 
+BCD number were truncated during conversion.
+
+Fixed a problem in the ToDecimal operator where the length of the resulting 
+string could be set incorrectly too long if the input operand was a Buffer 
+object.
+
+Fixed a problem in the Logical operators (LLess, etc.) where a NULL byte (0) 
+within a buffer would prematurely terminate a compare between buffer 
+objects.
+
+Added a check for string overflow (>200 characters as per the ACPI 
+specification) during the Concatenate operator with two string operands.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+
+2) iASL Compiler/Disassembler:
+
+Allow the use of the ObjectType operator on uninitialized Locals and Args 
+(returns 0 as per the ACPI specification).
+
+Fixed a problem where the compiler would fault if there was a syntax error 
+in the FieldName of all of the various CreateXXXField operators.
+
+Disallow the use of lower case letters within the EISAID macro, as per the 
+ACPI specification.  All EISAID strings must be of the form "UUUNNNN" Where 
+U is an uppercase letter and N is a hex digit.
+
+
+----------------------------------------
+06 October 2004.  Summary of changes for version 20041006:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for the ACPI 3.0 Timer operator. This ASL function 
+implements a 64-bit timer with 100 nanosecond granularity.
+
+Defined a new OSL interface, AcpiOsGetTimer. This interface is used to 
+implement the ACPI 3.0 Timer operator.  This allows the host OS to implement 
+the timer with the best clock available. Also, it keeps the core subsystem 
+out of the clock handling business, since the host OS (usually) performs 
+this function.
+
+Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write) 
+functions use a 64-bit address which is part of the packed ACPI Generic 
+Address Structure. Since the structure is non-aligned, the alignment macros 
+are now used to extract the address to a local variable before use.
+
+Fixed a problem where the ToInteger operator assumed all input strings were 
+hexadecimal. The operator now handles both decimal strings and hex strings 
+(prefixed with "0x").
+
+Fixed a problem where the string length in the string object created as a 
+result of the internal ConvertToString procedure could be incorrect. This 
+potentially affected all implicit conversions and also the ToDecimalString 
+and ToHexString operators.
+
+Fixed two problems in the ToString operator. If the length parameter was 
+zero, an incorrect string object was created and the value of the input 
+length parameter was inadvertently changed from zero to Ones.
+
+Fixed a problem where the optional ResourceSource string in the ExtendedIRQ 
+resource macro was ignored.
+
+Simplified the interfaces to the internal division functions, reducing code 
+size and complexity.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Implemented support for the ACPI 3.0 Timer operator.
+
+Fixed a problem where the Default() operator was inadvertently ignored in a 
+Switch/Case block.  This was a problem in the translation of the Switch 
+statement to If...Else pairs.
+
+Added support to allow a standalone Return operator, with no parentheses (or 
+operands).
+
+Fixed a problem with code generation for the ElseIf operator where the 
+translated Else...If parse tree was improperly constructed leading to the 
+loss of some code.
+
+----------------------------------------
+22 September 2004.  Summary of changes for version 20040922:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem with the implementation of the LNot() operator where "Ones" 
+was not returned for the TRUE case. Changed the code to return Ones instead 
+of (!Arg) which was usually 1. This change affects iASL constant folding for 
+this operator also.
+
+Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was not 
+initialized properly -- Now zero the entire buffer in this case where the 
+buffer already exists.
+
+Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32 
+Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all 
+related code considerably. This will require changes/updates to all OS 
+interface layers (OSLs.)
+
+Implemented a new external interface, AcpiInstallExceptionHandler, to allow 
+a system exception handler to be installed. This handler is invoked upon any 
+run-time exception that occurs during control method execution.
+
+Added support for the DSDT in AcpiTbFindTable. This allows the 
+DataTableRegion() operator to access the local copy of the DSDT.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below. These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code. The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size. Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Debug Version:     164.5K Code,  68.3K Data,  232.8K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem with constant folding and the LNot operator. LNot was 
+returning 1 in the TRUE case, not Ones as per the ACPI specification. This 
+could result in the generation of an incorrect folded/reduced constant.
+
+End-Of-File is now allowed within a "//"-style comment.  A parse error no 
+longer occurs if such a comment is at the very end of the input ASL source 
+file.
+
+Implemented the "-r" option to override the Revision in the table header. 
+The initial use of this option will be to simplify the evaluation of the AML 
+interpreter by allowing a single ASL source module to be compiled for either 
+32-bit or 64-bit integers.
+
+
+----------------------------------------
+27 August 2004.  Summary of changes for version 20040827:
+
+1) ACPI CA Core Subsystem:
+
+- Implemented support for implicit object conversion in the non-numeric 
+logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, and 
+LNotEqual.)  Any combination of Integers/Strings/Buffers may now be used; 
+the second operand is implicitly converted on the fly to match the type of 
+the first operand.  For example:
+
+    LEqual (Source1, Source2)
+
+Source1 and Source2 must each evaluate to an integer, a string, or a buffer. 
+The data type of Source1 dictates the required type of Source2. Source2 is 
+implicitly converted if necessary to match the type of Source1.
+
+- Updated and corrected the behavior of the string conversion support.  The 
+rules concerning conversion of buffers to strings (according to the ACPI 
+specification) are as follows:
+
+ToDecimalString - explicit byte-wise conversion of buffer to string of 
+decimal values (0-255) separated by commas. ToHexString - explicit byte-wise 
+conversion of buffer to string of hex values (0-FF) separated by commas. 
+ToString - explicit byte-wise conversion of buffer to string.  Byte-by-byte 
+copy with no transform except NULL terminated. Any other implicit buffer-to-
+string conversion - byte-wise conversion of buffer to string of hex values 
+(0-FF) separated by spaces.
+
+- Fixed typo in definition of AcpiGbl_EnableInterpreterSlack.
+
+- Fixed a problem in AcpiNsGetPathnameLength where the returned length was 
+one byte too short in the case of a node in the root scope.  This could 
+cause a fault during debug output.
+
+- Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+----------------------------------------
+16 August 2004.  Summary of changes for version 20040816:
+
+1) ACPI CA Core Subsystem:
+
+Designed and implemented support within the AML interpreter for the so-
+called "implicit return".  This support returns the result of the last ASL 
+operation within a control method, in the absence of an explicit Return() 
+operator.  A few machines depend on this behavior, even though it is not 
+explicitly supported by the ASL language.  It is optional support that can 
+be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag.
+
+Removed support for the PCI_Config address space from the internal low level 
+hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite).  This 
+support was not used internally, and would not work correctly anyway because 
+the PCI bus number and segment number were not supported.  There are 
+separate interfaces for PCI configuration space access because of the unique 
+interface.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.
+
+  Previous Release:
+    Non-Debug Version:  78.0K Code,  11.5K Data,   89.5K Total
+    Debug Version:     164.1K Code,  68.2K Data,  232.3K Total
+  Current Release:

+    Debug Version:     164.1K Code,  68.3K Data,  232.4K Total
+
+
+2) iASL Compiler/Disassembler:
+
+Fixed a problem where constants in ASL expressions at the root level (not 
+within a control method) could be inadvertently truncated during code 
+generation.  This problem was introduced in the 20040715 release.
+
+
+----------------------------------------
+15 July 2004.  Summary of changes for version 20040715:
+
+1) ACPI CA Core Subsystem:
+
+Restructured the internal HW GPE interfaces to pass/track the current state 
+of interrupts (enabled/disabled) in order to avoid possible deadlock and 
+increase flexibility of the interfaces.
+
+Implemented a "lexicographical compare" for String and Buffer objects within 
+the logical operators -- LGreater, LLess, LGreaterEqual, and LLessEqual -- 
+as per further clarification to the ACPI specification.  Behavior is similar 
+to C library "strcmp".
+
+Completed a major reduction in CPU stack use for the AcpiGetFirmwareTable 
+external function.  In the 32-bit non-debug case, the stack use has been 
+reduced from 168 bytes to 32 bytes.
+
+Deployed a new run-time configuration flag, AcpiGbl_EnableInterpreterSlack, 
+whose purpose is to allow the AML interpreter to forgive certain bad AML 
+constructs.  Default setting is FALSE.
+
+Implemented the first use of AcpiGbl_EnableInterpreterSlack in the Field IO 
+support code.  If enabled, it allows field access to go beyond the end of a 
+region definition if the field is within the region length rounded up to the 
+next access width boundary (a common coding error.)
+
+Renamed OSD_HANDLER to ACPI_OSD_HANDLER, and OSD_EXECUTION_CALLBACK to 
+ACPI_OSD_EXEC_CALLBACK for consistency with other ACPI symbols.  Also, these 
+symbols are lowercased by the latest version of the AcpiSrc tool.
+
+The prototypes for the PCI interfaces in acpiosxf.h have been updated to 
+rename "Register" to simply "Reg" to prevent certain compilers from 
+complaining.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:
+
+Implemented full support for Package objects within the Case() operator.  
+Note: The Break() operator is currently not supported within Case blocks 
+(TermLists) as there is some question about backward compatibility with ACPI 
+1.0 interpreters.
+
+
+Fixed a problem where complex terms were not supported properly within the 
+Switch() operator.
+
+Eliminated extraneous warning for compiler-emitted reserved names of the 
+form "_T_x".  (Used in Switch/Case operators.)
+
+Eliminated optimization messages for "_T_x" objects and small constants 
+within the DefinitionBlock operator.
+
+
+----------------------------------------
+15 June 2004.  Summary of changes for version 20040615:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for Buffer and String objects (as per ACPI 2.0) for the 
+following ASL operators:  LEqual, LGreater, LLess, LGreaterEqual, and 
+LLessEqual.
+
+All directory names in the entire source package are lower case, as they 
+were in earlier releases.
+
+Implemented "Disassemble" command in the AML debugger that will disassemble 
+a single control method.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+following ASL operators:  LEqual, LGreater, LLess, LGreaterEqual, and 
+LLessEqual.
+
+All directory names in the entire source package are lower case, as they 
+were in earlier releases.
+
+Fixed a fault when using the -g or -d<nofilename> options if the FADT was 
+not found.
+
+Fixed an issue with the Windows version of the compiler where later versions 
+of Windows place the FADT in the registry under the name "FADT" and not 
+"FACP" as earlier versions did.  This applies when using the -g or -
+d<nofilename> options.  The compiler now looks for both strings as 
+necessary.
+
+Fixed a problem with compiler namepath optimization where a namepath within 
+the Scope() operator could not be optimized if the namepath was a subpath of 
+the current scope path.
+
+----------------------------------------
+27 May 2004.  Summary of changes for version 20040527:
+
+1) ACPI CA Core Subsystem:
+
+Completed a new design and implementation for EBDA (Extended BIOS Data Area) 
+support in the RSDP scan code.  The original code improperly scanned for the 
+EBDA by simply scanning from memory location 0 to 0x400.  The correct method 
+is to first obtain the EBDA pointer from within the BIOS data area, then 
+scan 1K of memory starting at the EBDA pointer.  There appear to be few if 
+any machines that place the RSDP in the EBDA, however.
+
+Integrated a fix for a possible fault during evaluation of BufferField 
+arguments.  Obsolete code that was causing the problem was removed.
+
+Found and fixed a problem in the Field Support Code where data could be 
+corrupted on a bit field read that starts on an aligned boundary but does 
+not end on an aligned boundary.  Merged the read/write "datum length" 
+calculation code into a common procedure.
+
+Rolled in a couple of changes to the FreeBSD-specific header.
+
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+64-bit constant.
+
+----------------------------------------
+14 May 2004.  Summary of changes for version 20040514:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where hardware GPE enable bits sometimes not set properly 
+during and after GPE method execution.  Result of 04/27 changes.
+
+Removed extra "clear all GPEs" when sleeping/waking.
+
+Removed AcpiHwEnableGpe and AcpiHwDisableGpe, replaced by the single 
+AcpiHwWriteGpeEnableReg. Changed a couple of calls to the functions above to 
+the new AcpiEv* calls as appropriate.
+
+ACPI_OS_NAME was removed from the OS-specific headers.  The default name is 
+now "Microsoft Windows NT" for maximum compatibility.  However this can be 
+changed by modifying the acconfig.h file.
+
+Allow a single invocation of AcpiInstallNotifyHandler for a handler that 
+traps both types of notifies (System, Device).  Use ACPI_ALL_NOTIFY flag. 
+
+Run _INI methods on ThermalZone objects.  This is against the ACPI 
+specification, but there is apparently ASL code in the field that has these 
+_INI methods, and apparently "other" AML interpreters execute them.
+
+Performed a full 16/32/64 bit lint that resulted in some small changes.
+
+Added a sleep simulation command to the AML debugger to test sleep code. 
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the

+that these values will vary depending on the efficiency of the compiler and

+----------------------------------------
+27 April 2004.  Summary of changes for version 20040427:
+
+1) ACPI CA Core Subsystem:
+
+Completed a major overhaul of the GPE handling within ACPI CA.  There are 
+now three types of GPEs:  wake-only, runtime-only, and combination wake/run.  
+The only GPEs allowed to be combination wake/run are for button-style 
+devices such as a control-method power button, control-method sleep button, 
+or a notebook lid switch.  GPEs that have an _Lxx or _Exx method and are not 
+referenced by any _PRW methods are marked for "runtime" and hardware 
+enabled.  Any GPE that is referenced by a _PRW method is marked for "wake" 
+(and disabled at runtime).  However, at sleep time, only those GPEs that 
+have been specifically enabled for wake via the AcpiEnableGpe interface will 
+actually be hardware enabled.
+
+A new external interface has been added, AcpiSetGpeType(), that is meant to 
+be used by device drivers to force a GPE to a particular type.  It will be 
+especially useful for the drivers for the button devices mentioned above.
+
+Completed restructuring of the ACPI CA initialization sequence so that 
+default operation region handlers are installed before GPEs are initialized 
+and the _PRW methods are executed.  This will prevent errors when the _PRW 
+methods attempt to access system memory or I/O space.
+
+GPE enable/disable no longer reads the GPE enable register.  We now keep the 
+enable info for runtime and wake separate and in the GPE_EVENT_INFO.  We 
+thus no longer depend on the hardware to maintain these bits.
+
+Always clear the wake status and fixed/GPE status bits before sleep, even 
+for state S5.
+
+Improved the AML debugger output for displaying the GPE blocks and their 
+current status.
+
+Added new strings for the _OSI method, of the form "Windows 2001 SPx" where 
+x = 0,1,2,3,4.
+
+Fixed a problem where the physical address was incorrectly calculated when 
+the Load() operator was used to directly load from an Operation Region (vs. 
+loading from a Field object.)  Also added check for minimum table length for 
+this case.
+
+Fix for multiple mutex acquisition.  Restore original thread SyncLevel on 
+mutex release.
+
+Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for 
+consistency with the other fields returned.
+
+Shrunk the ACPI_GPE_EVENT_INFO structure by 40%.  There is one such 
+structure for each GPE in the system, so the size of this structure is 
+important.
+
+CPU stack requirement reduction:  Cleaned up the method execution and object 
+evaluation paths so that now a parameter structure is passed, instead of 
+copying the various method parameters over and over again.
+
+In evregion.c:  Correctly exit and reenter the interpreter region if and 
+only if dispatching an operation region request to a user-installed handler.  
+Do not exit/reenter when dispatching to a default handler (e.g., default 
+system memory or I/O handlers)
+
+
+Notes for updating drivers for the new GPE support.  The following changes 
+must be made to ACPI-related device drivers that are attached to one or more 
+GPEs: (This information will be added to the ACPI CA Programmer Reference.)
+
+1) AcpiInstallGpeHandler no longer automatically enables the GPE, you must 
+explicitly call AcpiEnableGpe.
+2) There is a new interface called AcpiSetGpeType. This should be called 
+before enabling the GPE.  Also, this interface will automatically disable 
+the GPE if it is currently enabled.
+3) AcpiEnableGpe no longer supports a GPE type flag.
+
+Specific drivers that must be changed:
+1) EC driver:
+    AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED, 
+AeGpeHandler, NULL);
+    AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME);
+    AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR);
+
+2) Button Drivers (Power, Lid, Sleep):
+Run _PRW method under parent device
+If _PRW exists: /* This is a control-method button */
+    Extract GPE number and possibly GpeDevice
+    AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN);
+    AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR);
+
+For all other devices that have _PRWs, we automatically set the GPE type to 
+ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled.  This 
+must be done on a selective basis, usually requiring some kind of user app 
+to allow the user to pick the wake devices.
+
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+----------------------------------------
+02 April 2004.  Summary of changes for version 20040402:
+
+1) ACPI CA Core Subsystem:
+
+Fixed an interpreter problem where an indirect store through an ArgX 
+parameter was incorrectly applying the "implicit conversion rules" during 
+the store.  From the ACPI specification: "If the target is a method local or 
+argument (LocalX or ArgX), no conversion is performed and the result is 
+stored directly to the target".  The new behavior is to disable implicit 
+conversion during ALL stores to an ArgX.
+
+Changed the behavior of the _PRW method scan to ignore any and all errors 
+returned by a given _PRW.  This prevents the scan from aborting from the 
+failure of any single _PRW.
+
+Moved the runtime configuration parameters from the global init procedure to 
+static variables in acglobal.h.  This will allow the host to override the 
+default values easily.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+    Debug Version:     160.8K Code,  66.1K Data,  226.9K Total

+    Debug Version:     161.0K Code,  66.3K Data,  227.3K Total
+
+
+2) iASL Compiler/Disassembler:
+
+iASL now fully disassembles SSDTs.  However, External() statements are not 
+generated automatically for unresolved symbols at this time.  This is a 
+planned feature for future implementation.
+
+Fixed a scoping problem in the disassembler that occurs when the type of the 
+target of a Scope() operator is overridden.  This problem caused an 
+incorrectly nested internal namespace to be constructed.
+
+Any warnings or errors that are emitted during disassembly are now commented 
+out automatically so that the resulting file can be recompiled without any 
+hand editing.
+
+----------------------------------------
+26 March 2004.  Summary of changes for version 20040326:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for "wake" GPEs via interaction between GPEs and the 
+_PRW methods.  Every GPE that is pointed to by one or more _PRWs is 
+identified as a WAKE GPE and by default will no longer be enabled at 
+runtime.  Previously, we were blindly enabling all GPEs with a corresponding 
+_Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway.  We 
+believe this has been the cause of thousands of "spurious" GPEs on some 
+systems.
+
+This new GPE behavior is can be reverted to the original behavior (enable 
+ALL GPEs at runtime) via a runtime flag.
+
+Fixed a problem where aliased control methods could not access objects 
+properly.  The proper scope within the namespace was not initialized 
+(transferred to the target of the aliased method) before executing the 
+target method.
+
+Fixed a potential race condition on internal object deletion on the return 
+object in AcpiEvaluateObject. 
+
+Integrated a fix for resource descriptors where both _MEM and _MTP were 
+being extracted instead of just _MEM.  (i.e. bitmask was incorrectly too 
+wide, 0x0F instead of 0x03.)
+
+Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, preventing a 
+fault in some cases.
+
+Updated Notify() values for debug statements in evmisc.c
+
+Return proper status from AcpiUtMutexInitialize, not just simply AE_OK.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+
+----------------------------------------
+11 March 2004.  Summary of changes for version 20040311:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where errors occurring during the parse phase of control 
+method execution did not abort cleanly.  For example, objects created and 
+installed in the namespace were not deleted.  This caused all subsequent 
+invocations of the method to return the AE_ALREADY_EXISTS exception.
+
+Implemented a mechanism to force a control method to "Serialized" execution 
+if the method attempts to create namespace objects. (The root of the 
+AE_ALREADY_EXISTS problem.)
+
+Implemented support for the predefined _OSI "internal" control method.  
+Initial supported strings are "Linux", "Windows 2000", "Windows 2001", and 
+"Windows 2001.1", and can be easily upgraded for new strings as necessary.  
+This feature will allow "other" operating systems to execute the fully 
+tested, "Windows" code path through the ASL code
+
+Global Lock Support:  Now allows multiple acquires and releases with any 
+internal thread.  Removed concept of "owning thread" for this special mutex.
+
+Fixed two functions that were inappropriately declaring large objects on the 
+CPU stack:  PsParseLoop, NsEvaluateRelative.  Reduces the stack usage during 
+method execution considerably.
+
+Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the 
+S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
+
+Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs 
+defined on the machine.
+
+Implemented two runtime options:  One to force all control method execution 
+to "Serialized" to mimic Windows behavior, another to disable _OSI support 
+if it causes problems on a given machine.
+
+Code and Data Size: Current and previous core subsystem library sizes are 
+shown below.  These are the code and data sizes for the acpica.lib produced 
+by the Microsoft Visual C++ 6.0 compiler, and these values do not include 
+any ACPI driver or OSPM code.  The debug version of the code includes the 
+debug output trace mechanism and has a much larger code and data size.  Note 
+that these values will vary depending on the efficiency of the compiler and 
+the compiler options used during generation.

+fault.
+
+----------------------------------------
+20 February 2004.  Summary of changes for version 20040220:
+
+
+1) ACPI CA Core Subsystem:
+
+Implemented execution of _SxD methods for Device objects in the 
+GetObjectInfo interface.
+
+Fixed calls to _SST method to pass the correct arguments.
+
+Added a call to _SST on wake to restore to "working" state.
+
+Check for End-Of-Buffer failure case in the WalkResources interface.
+
+Integrated fix for 64-bit alignment issue in acglobal.h by moving two 
+structures to the beginning of the file.
+
+After wake, clear GPE status register(s) before enabling GPEs.
+
+After wake, clear/enable power button.  (Perhaps we should clear/enable all 
+fixed events upon wake.)
+
+Fixed a couple of possible memory leaks in the Namespace manager.
+
+Integrated latest acnetbsd.h file.
+
+----------------------------------------
+11 February 2004.  Summary of changes for version 20040211:
+
+
+1) ACPI CA Core Subsystem:
+
+Completed investigation and implementation of the call-by-reference 
+mechanism for control method arguments.
+
+Fixed a problem where a store of an object into an indexed package could 
+fail if the store occurs within a different method than the method that 
+created the package.
+
+Fixed a problem where the ToDecimal operator could return incorrect results.
+
+Fixed a problem where the CopyObject operator could fail on some of the more 
+obscure objects (e.g., Reference objects.)
+
+Improved the output of the Debug object to display buffer, package, and 
+index objects.
+
+Fixed a problem where constructs of the form "RefOf (ArgX)" did not return 
+the expected result.
+
+Added permanent ACPI_REPORT_ERROR macros for all instances of the 
+ACPI_AML_INTERNAL exception.
+
+Integrated latest version of acfreebsd.h
+
+----------------------------------------
+16 January 2004.  Summary of changes for version 20040116:
+
+The purpose of this release is primarily to update the copyright years in 
+each module, thus causing a huge number of diffs.  There are a few small 
+functional changes, however.
+
+1) ACPI CA Core Subsystem:
+
+Improved error messages when there is a problem finding one or more of the 
+required base ACPI tables
+
+Reintroduced the definition of APIC_HEADER in actbl.h
+
+Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)
+
+Removed extraneous reference to NewObj in dsmthdat.c
+
+2) iASL compiler
+
+Fixed a problem introduced in December that disabled the correct disassembly 
+of Resource Templates
+
+
+----------------------------------------
+03 December 2003.  Summary of changes for version 20031203:
+
+1) ACPI CA Core Subsystem:
+
+Changed the initialization of Operation Regions during subsystem
+init to perform two entire walks of the ACPI namespace; The first
+to initialize the regions themselves, the second to execute the
+_REG methods.  This fixed some interdependencies across _REG
+methods found on some machines.
+
+Fixed a problem where a Store(Local0, Local1) could simply update
+the object reference count, and not create a new copy of the
+object if the Local1 is uninitialized.
+
+Implemented support for the _SST reserved method during sleep
+transitions.
+
+Implemented support to clear the SLP_TYP and SLP_EN bits when
+waking up, this is apparently required by some machines.
+
+When sleeping, clear the wake status only if SleepState is not S5.
+
+Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect
+pointer arithmetic advanced a string pointer too far.
+
+Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer
+could be returned if the requested table has not been loaded.
+
+Within the support for IRQ resources, restructured the handling of
+the active and edge/level bits.
+
+Fixed a few problems in AcpiPsxExecute() where memory could be
+leaked under certain error conditions.
+
+Improved error messages for the cases where the ACPI mode could
+not be entered.
+
+Code and Data Size: Current and previous core subsystem library
+sizes are shown below.  These are the code and data sizes for the
+acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
+these values do not include any ACPI driver or OSPM code.  The
+debug version of the code includes the debug output trace
+mechanism and has a much larger code and data size.  Note that
+these values will vary depending on the efficiency of the compiler
+and the compiler options used during generation.

+
+2) iASL Compiler/Disassembler:
+
+Implemented a fix for the iASL disassembler where a bad index was
+generated.  This was most noticeable on 64-bit platforms
+
+
+----------------------------------------
+29 October 2003.  Summary of changes for version 20031029:
+
+1) ACPI CA Core Subsystem:
+
+
+Fixed a problem where a level-triggered GPE with an associated
+_Lxx control method was incorrectly cleared twice.
+
+Fixed a problem with the Field support code where an access can
+occur beyond the end-of-region if the field is non-aligned but
+extends to the very end of the parent region (resulted in an
+AE_AML_REGION_LIMIT exception.)
+
+Fixed a problem with ACPI Fixed Events where an RT Clock handler
+would not get invoked on an RTC event.  The RTC event bitmasks for
+the PM1 registers were not being initialized properly.
+
+Implemented support for executing _STA and _INI methods for
+Processor objects.  Although this is currently not part of the
+ACPI specification, there is existing ASL code that depends on the
+init-time execution of these methods.
+
+Implemented and deployed a GetDescriptorName function to decode
+the various types of internal descriptors.  Guards against null
+descriptors during debug output also.
+
+Implemented and deployed a GetNodeName function to extract the 4-
+character namespace node name.  This function simplifies the debug
+and error output, as well as guarding against null pointers during
+output.
+
+Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to
+simplify the debug and error output of 64-bit integers.  This
+macro replaces the HIDWORD and LODWORD macros for dumping these
+integers.
+
+Updated the implementation of the Stall() operator to only call
+AcpiOsStall(), and also return an error if the operand is larger
+than 255.  This preserves the required behavior of not
+relinquishing the processor, as would happen if AcpiOsSleep() was
+called for "long stalls".
+
+Constructs of the form "Store(LocalX,LocalX)" where LocalX is not
+initialized are now treated as NOOPs.
+
+Cleaned up a handful of warnings during 64-bit generation.
+
+Fixed a reported error where and incorrect GPE number was passed
+to the GPE dispatch handler.  This value is only used for error
+output, however.  Used this opportunity to clean up and streamline
+the GPE dispatch code.
+
+Code and Data Size: Current and previous core subsystem library
+sizes are shown below.  These are the code and data sizes for the
+acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
+these values do not include any ACPI driver or OSPM code.  The
+
+debug version of the code includes the debug output trace
+mechanism and has a much larger code and data size.  Note that
+these values will vary depending on the efficiency of the compiler
+and the compiler options used during generation.

+
+
+2) iASL Compiler/Disassembler:

+Updated the iASL compiler to return an error if the operand to the
+Stall() operator is larger than 255.
+
+
+----------------------------------------
+02 October 2003.  Summary of changes for version 20031002:
+
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem with Index Fields where the index was not
+incremented for fields that require multiple writes to the
+index/data registers (Fields that are wider than the data
+register.)
+
+Fixed a problem with all Field objects where a write could go
+beyond the end-of-field if the field was larger than the access
+granularity and therefore required multiple writes to complete the
+request.  An extra write beyond the end of the field could happen
+inadvertently.
+
+Fixed a problem with Index Fields where a BUFFER_OVERFLOW error
+would incorrectly be returned if the width of the Data Register
+was larger than the specified field access width.
+
+Completed fixes for LoadTable() and Unload() and verified their
+operation.  Implemented full support for the "DdbHandle" object
+throughout the ACPI CA subsystem.
+
+Implemented full support for the MADT and ECDT tables in the ACPI
+CA header files.  Even though these tables are not directly
+consumed by ACPI CA, the header definitions are useful for ACPI
+device drivers.
+
+Integrated resource descriptor fixes posted to the Linux ACPI
+list.  This included checks for minimum descriptor length, and
+support for trailing NULL strings within descriptors that have
+optional string elements.
+
+Code and Data Size: Current and previous core subsystem library
+sizes are shown below.  These are the code and data sizes for the
+acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
+these values do not include any ACPI driver or OSPM code.  The
+debug version of the code includes the debug output trace
+mechanism and has a much larger code and data size.  Note that
+these values will vary depending on the efficiency of the compiler
+and the compiler options used during generation.

+
+
+2) iASL Compiler:
+
+Implemented detection of non-ASCII characters within the input
+source ASL file.  This catches attempts to compile binary (AML)
+files early in the compile, with an informative error message.
+
+Fixed a problem where the disassembler would fault if the output
+filename could not be generated or if the output file could not be
+opened.
+
+----------------------------------------
+18 September 2003.  Summary of changes for version 20030918:
+
+
+1) ACPI CA Core Subsystem:
+
+Found and fixed a longstanding problem with the late execution of
+the various deferred AML opcodes (such as Operation Regions,
+Buffer Fields, Buffers, and Packages).  If the name string
+specified for the name of the new object placed the object in a
+scope other than the current scope, the initialization/execution
+of the opcode failed.  The solution to this problem was to
+implement a mechanism where the late execution of such opcodes
+does not attempt to lookup/create the name a second time in an
+incorrect scope.  This fixes the "region size computed
+incorrectly" problem.
+
+Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a
+Global Lock AE_BAD_PARAMETER error.
+
+Fixed several 64-bit issues with prototypes, casting and data
+types.
+
+Removed duplicate prototype from acdisasm.h
+
+Fixed an issue involving EC Operation Region Detach (Shaohua Li)
+
+Code and Data Size: Current and previous core subsystem library
+sizes are shown below.  These are the code and data sizes for the
+acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
+these values do not include any ACPI driver or OSPM code.  The

+
+
+2) Linux:

+correct sleep time in seconds.
+
+----------------------------------------
+14 July 2003.  Summary of changes for version 20030619:
+
+1) ACPI CA Core Subsystem:
+
+Parse SSDTs in order discovered, as opposed to reverse order
+(Hrvoje Habjanic)
+
+Fixes from FreeBSD and NetBSD. (Frank van der Linden, Thomas
+Klausner,
+   Nate Lawson)
+
+
+2) Linux:
+
+Dynamically allocate SDT list (suggested by Andi Kleen)
+
+proc function return value cleanups (Andi Kleen)
+
+Correctly handle NMI watchdog during long stalls (Andrew Morton)
+
+Make it so acpismp=force works (reported by Andrew Morton)
+
+
+----------------------------------------
+19 June 2003.  Summary of changes for version 20030619:
+
+1) ACPI CA Core Subsystem:
+
+Fix To/FromBCD, eliminating the need for an arch-specific #define.
+
+Do not acquire a semaphore in the S5 shutdown path.
+
+Fix ex_digits_needed for 0. (Takayoshi Kochi)
+
+Fix sleep/stall code reversal. (Andi Kleen)
+
+Revert a change having to do with control method calling
+semantics.
+
+2) Linux:
+
+acpiphp update (Takayoshi Kochi)
+
+Export acpi_disabled for sonypi (Stelian Pop)
+
+Mention acpismp=force in config help
+
+Re-add acpitable.c and acpismp=force. This improves backwards
+
+compatibility and also cleans up the code to a significant degree.
+
+Add ASUS Value-add driver (Karol Kozimor and Julien Lerouge)
+
+----------------------------------------
+22 May 2003.  Summary of changes for version 20030522:
+
+1) ACPI CA Core Subsystem:
+
+Found and fixed a reported problem where an AE_NOT_FOUND error
+occurred occasionally during _BST evaluation.  This turned out to
+be an Owner ID allocation issue where a called method did not get
+a new ID assigned to it.  Eventually, (after 64k calls), the Owner
+ID UINT16 would wraparound so that the ID would be the same as the
+caller's and the called method would delete the caller's
+namespace.
+
+Implemented extended error reporting for control methods that are
+aborted due to a run-time exception.  Output includes the exact
+AML instruction that caused the method abort, a dump of the method
+locals and arguments at the time of the abort, and a trace of all
+nested control method calls.
+
+Modified the interpreter to allow the creation of buffers of zero
+length from the AML code. Implemented new code to ensure that no
+attempt is made to actually allocate a memory buffer (of length
+zero) - instead, a simple buffer object with a NULL buffer pointer
+and length zero is created.  A warning is no longer issued when
+the AML attempts to create a zero-length buffer.
+
+Implemented a workaround for the "leading asterisk issue" in
+_HIDs, _UIDs, and _CIDs in the AML interpreter.  One leading
+asterisk is automatically removed if present in any HID, UID, or
+CID strings.  The iASL compiler will still flag this asterisk as
+an error, however.
+
+Implemented full support for _CID methods that return a package of
+multiple CIDs (Compatible IDs).  The AcpiGetObjectInfo() interface
+now additionally returns a device _CID list if present.  This
+required a change to the external interface in order to pass an
+ACPI_BUFFER object as a parameter since the _CID list is of
+variable length.
+
+Fixed a problem with the new AE_SAME_HANDLER exception where
+handler initialization code did not know about this exception.
+
+Code and Data Size: Current and previous core subsystem library
+sizes are shown below.  These are the code and data sizes for the
+acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
+these values do not include any ACPI driver or OSPM code.  The
+debug version of the code includes the debug output trace
+mechanism and has a much larger code and data size.  Note that
+these values will vary depending on the efficiency of the compiler
+and the compiler options used during generation.

+
+
+2) Linux:
+
+Fixed a bug in which we would reinitialize the ACPI interrupt
+after it was already working, thus disabling all ACPI and the IRQs
+for any other device sharing the interrupt. (Thanks to Stian
+Jordet)
+
+Toshiba driver update (John Belmonte)
+
+Return only 0 or 1 for our interrupt handler status (Andrew
+Morton)
+
+
+3) iASL Compiler:
+
+Fixed a reported problem where multiple (nested) ElseIf()
+statements were not handled correctly by the compiler, resulting
+in incorrect warnings and incorrect AML code.  This was a problem
+in both the ASL parser and the code generator.
+
+
+4) Documentation:
+
+Added changes to existing interfaces, new exception codes, and new
+text concerning reference count object management versus garbage
+collection.
+
+----------------------------------------
+09 May 2003.  Summary of changes for version 20030509.
+
+
+1) ACPI CA Core Subsystem:
+
+Changed the subsystem initialization sequence to hold off
+installation of address space handlers until the hardware has been
+initialized and the system has entered ACPI mode.  This is because
+the installation of space handlers can cause _REG methods to be
+run.  Previously, the _REG methods could potentially be run before
+ACPI mode was enabled.
+
+Fixed some memory leak issues related to address space handler and
+notify handler installation.  There were some problems with the
+reference count mechanism caused by the fact that the handler
+objects are shared across several namespace objects.
+
+Fixed a reported problem where reference counts within the
+namespace were not properly updated when named objects created by
+method execution were deleted.
+
+Fixed a reported problem where multiple SSDTs caused a deletion
+issue during subsystem termination.  Restructured the table data
+structures to simplify the linked lists and the related code.
+
+Fixed a problem where the table ID associated with secondary
+tables (SSDTs) was not being propagated into the namespace objects
+created by those tables.  This would only present a problem for
+tables that are unloaded at run-time, however.
+
+Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE
+type as the length parameter (instead of UINT32).
+
+Solved a long-standing problem where an ALREADY_EXISTS error
+appears on various systems.  This problem could happen when there
+are multiple PCI_Config operation regions under a single PCI root
+bus.  This doesn't happen very frequently, but there are some
+systems that do this in the ASL.
+
+Fixed a reported problem where the internal DeleteNode function
+was incorrectly handling the case where a namespace node was the
+first in the parent's child list, and had additional peers (not
+the only child, but first in the list of children.)
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+2) Linux:
+
+Allow ":" in OS override string (Ducrot Bruno)
+
+Kobject fix (Greg KH)
+
+
+3 iASL Compiler/Disassembler:
+
+Fixed a problem in the generation of the C source code files (AML
+is emitted in C source statements for BIOS inclusion) where the
+Ascii dump that appears within a C comment at the end of each line
+could cause a compile time error if the AML sequence happens to
+have an open comment or close comment sequence embedded.
+
+
+----------------------------------------
+24 April 2003.  Summary of changes for version 20030424.
+
+
+1) ACPI CA Core Subsystem:
+
+Support for big-endian systems has been implemented.  Most of the
+support has been invisibly added behind big-endian versions of the
+ACPI_MOVE_* macros.
+
+Fixed a problem in AcpiHwDisableGpeBlock() and
+AcpiHwClearGpeBlock() where an incorrect offset was passed to the
+low level hardware write routine.  The offset parameter was
+actually eliminated from the low level read/write routines because
+they had become obsolete.
+
+Fixed a problem where a handler object was deleted twice during
+the removal of a fixed event handler.
+
+
+2) Linux:
+
+A fix for SMP systems with link devices was contributed by
+
+Compaq's Dan Zink.
+
+(2.5) Return whether we handled the interrupt in our IRQ handler.
+(Linux ISRs no longer return void, so we can propagate the handler
+return value from the ACPI CA core back to the OS.)
+
+
+
+3) Documentation:
+
+The ACPI CA Programmer Reference has been updated to reflect new
+interfaces and changes to existing interfaces.
+
+----------------------------------------
+28 March 2003.  Summary of changes for version 20030328.
+
+1) ACPI CA Core Subsystem:
+
+The GPE Block Device support has been completed.  New interfaces
+are AcpiInstallGpeBlock and AcpiRemoveGpeBlock.  The Event
+interfaces (enable, disable, clear, getstatus) have been split
+into separate interfaces for Fixed Events and General Purpose
+Events (GPEs) in order to support GPE Block Devices properly.
+
+Fixed a problem where the error message "Failed to acquire
+semaphore" would appear during operations on the embedded
+controller (EC).
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+----------------------------------------
+28 February 2003.  Summary of changes for version 20030228.
+
+
+1) ACPI CA Core Subsystem:
+
+The GPE handling and dispatch code has been completely overhauled
+in preparation for support of GPE Block Devices (ID ACPI0006).
+This affects internal data structures and code only; there should
+be no differences visible externally.  One new file has been
+added, evgpeblk.c
+
+The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only
+fields that are used to determine the GPE block lengths.  The
+REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address
+structures are ignored.  This is per the ACPI specification but it
+isn't very clear.  The full 256 Block 0/1 GPEs are now supported
+(the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128).
+
+In the SCI interrupt handler, removed the read of the PM1_CONTROL
+register to look at the SCI_EN bit.  On some machines, this read
+causes an SMI event and greatly slows down SCI events.  (This may
+in fact be the cause of slow battery status response on some
+systems.)
+
+Fixed a problem where a store of a NULL string to a package object
+could cause the premature deletion of the object.  This was seen
+during execution of the battery _BIF method on some systems,
+resulting in no battery data being returned.
+
+Added AcpiWalkResources interface to simplify parsing of resource
+lists.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+2) Linux
+
+S3 fixes (Ole Rohne)
+
+Update ACPI PHP driver with to use new acpi_walk_resource API
+(Bjorn Helgaas)
+
+Add S4BIOS support (Pavel Machek)
+
+Map in entire table before performing checksum (John Stultz)
+
+Expand the mem= cmdline to allow the specification of reserved and
+ACPI DATA blocks (Pavel Machek)
+
+Never use ACPI on VISWS
+
+Fix derive_pci_id (Ducrot Bruno, Alvaro Lopez)
+
+Revert a change that allowed P_BLK lengths to be 4 or 5. This is
+causing us to think that some systems support C2 when they really
+don't.
+
+Do not count processor objects for non-present CPUs (Thanks to
+Dominik Brodowski)
+
+
+3) iASL Compiler:
+
+Fixed a problem where ASL include files could not be found and
+opened.
+
+Added support for the _PDC reserved name.
+
+
+----------------------------------------
+22 January 2003.  Summary of changes for version 20030122.
+
+
+1) ACPI CA Core Subsystem:
+
+Added a check for constructs of the form:  Store (Local0, Local0)
+where Local0 is not initialized.  Apparently, some BIOS
+programmers believe that this is a NOOP.  Since this store doesn't
+do anything anyway, the new prototype behavior will ignore this
+error.  This is a case where we can relax the strict checking in
+the interpreter in the name of compatibility.
+
+
+2) Linux
+
+The AcpiSrc Source Conversion Utility has been released with the
+Linux package for the first time.  This is the utility that is
+used to convert the ACPI CA base source code to the Linux version.
+
+(Both) Handle P_BLK lengths shorter than 6 more gracefully
+
+(Both) Move more headers to include/acpi, and delete an unused
+header.
+
+(Both) Move drivers/acpi/include directory to include/acpi
+
+(Both) Boot functions don't use cmdline, so don't pass it around
+
+(Both) Remove include of unused header (Adrian Bunk)
+
+(Both) acpiphp.h includes both linux/acpi.h and acpi_bus.h. Since
+the
+former now also includes the latter, acpiphp.h only needs the one,
+now.
+
+(2.5) Make it possible to select method of bios restoring after S3
+resume. [=> no more ugly ifdefs] (Pavel Machek)
+
+(2.5) Make proc write interfaces work (Pavel Machek)
+
+(2.5) Properly init/clean up in cpufreq/acpi (Dominik Brodowski)
+
+(2.5) Break out ACPI Perf code into its own module, under cpufreq
+(Dominik Brodowski)
+
+(2.4) S4BIOS support (Ducrot Bruno)
+
+(2.4) Fix acpiphp_glue.c for latest ACPI struct changes (Sergio
+Visinoni)
+
+
+3) iASL Compiler:
+
+Added support to disassemble SSDT and PSDTs.
+
+Implemented support to obtain SSDTs from the Windows registry if
+available.
+
+
+----------------------------------------
+09 January 2003.  Summary of changes for version 20030109.
+
+1) ACPI CA Core Subsystem:
+
+Changed the behavior of the internal Buffer-to-String conversion
+function.  The current ACPI specification states that the contents
+of the buffer are "converted to a string of two-character
+hexadecimal numbers, each separated by a space".  Unfortunately,
+this definition is not backwards compatible with existing ACPI 1.0
+implementations (although the behavior was not defined in the ACPI
+1.0 specification).  The new behavior simply copies data from the
+buffer to the string until a null character is found or the end of
+the buffer is reached.  The new String object is always null
+terminated.  This problem was seen during the generation of _BIF
+battery data where incorrect strings were returned for battery
+type, etc.  This will also require an errata to the ACPI
+specification.
+
+Renamed all instances of NATIVE_UINT and NATIVE_INT to
+ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively.
+
+Copyright in all module headers (both Linux and non-Linux) has be
+updated to 2003.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+2) Linux
+
+Fixed an oops on module insertion/removal (Matthew Tippett)
+
+(2.4) Fix to handle dynamic size of mp_irqs (Joerg Prante)
+
+(2.5) Replace pr_debug (Randy Dunlap)
+
+(2.5) Remove usage of CPUFREQ_ALL_CPUS (Dominik Brodowski)
+
+(Both) Eliminate spawning of thread from timer callback, in favor
+of schedule_work()
+
+(Both) Show Lid status in /proc (Zdenek OGAR Skalak)
+
+(Both) Added define for Fixed Function HW region (Matthew Wilcox)
+
+(Both) Add missing statics to button.c (Pavel Machek)
+
+Several changes have been made to the source code translation
+utility that generates the Linux Code in order to make the code
+more "Linux-like":
+
+All typedefs on structs and unions have been removed in keeping
+with the Linux coding style.
+
+Removed the non-Linux SourceSafe module revision number from each
+module header.
+
+Completed major overhaul of symbols to be lowercased for linux.
+Doubled the number of symbols that are lowercased.
+
+Fixed a problem where identifiers within procedure headers and
+within quotes were not fully lower cased (they were left with a
+starting capital.)
+
+Some C macros whose only purpose is to allow the generation of 16-
+bit code are now completely removed in the Linux code, increasing
+readability and maintainability.
+
+----------------------------------------
+
+12 December 2002.  Summary of changes for version 20021212.
+
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where the creation of a zero-length AML Buffer
+would cause a fault.
+
+Fixed a problem where a Buffer object that pointed to a static AML
+buffer (in an ACPI table) could inadvertently be deleted, causing
+memory corruption.
+
+Fixed a problem where a user buffer (passed in to the external
+ACPI CA interfaces) could be overwritten if the buffer was too
+small to complete the operation, causing memory corruption.
+
+Fixed a problem in the Buffer-to-String conversion code where a
+string of length one was always returned, regardless of the size
+of the input Buffer object.
+
+Removed the NATIVE_CHAR data type across the entire source due to
+lack of need and lack of consistent use.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler

+
+
+----------------------------------------
+05 December 2002.  Summary of changes for version 20021205.
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where a store to a String or Buffer object could
+cause corruption of the DSDT if the object type being stored was
+the same as the target object type and the length of the object
+being stored was equal to or smaller than the original (existing)
+target object.  This was seen to cause corruption of battery _BIF
+buffers if the _BIF method modified the buffer on the fly.
+
+Fixed a problem where an internal error was generated if a control
+method invocation was used in an OperationRegion, Buffer, or
+Package declaration.  This was caused by the deferred parsing of
+the control method and thus the deferred creation of the internal
+method object.  The solution to this problem was to create the
+internal method object at the moment the method is encountered in
+the first pass - so that subsequent references to the method will
+able to obtain the required parameter count and thus properly
+parse the method invocation.  This problem presented itself as an
+AE_AML_INTERNAL during the pass 1 parse phase during table load.
+
+Fixed a problem where the internal String object copy routine did
+not always allocate sufficient memory for the target String object
+and caused memory corruption.  This problem was seen to cause
+"Allocation already present in list!" errors as memory allocation
+became corrupted.
+
+Implemented a new function for the evaluation of namespace objects
+that allows the specification of the allowable return object
+types.  This simplifies a lot of code that checks for a return
+object of one or more specific objects returned from the
+evaluation (such as _STA, etc.)  This may become and external
+function if it would be useful to ACPI-related drivers.
+
+Completed another round of prefixing #defines with "ACPI_" for
+clarity.
+
+Completed additional code restructuring to allow more modular
+linking for iASL compiler and AcpiExec.  Several files were split
+creating new files.  New files:  nsparse.c dsinit.c evgpe.c
+
+Implemented an abort mechanism to terminate an executing control
+method via the AML debugger.  This feature is useful for debugging
+control methods that depend (wait) for specific hardware
+responses.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+2) iASL Compiler/Disassembler
+
+Fixed a compiler code generation problem for "Interrupt" Resource
+Descriptors.  If specified in the ASL, the optional "Resource
+Source Index" and "Resource Source" fields were not inserted into
+the correct location within the AML resource descriptor, creating
+an invalid descriptor.
+
+Fixed a disassembler problem for "Interrupt" resource descriptors.
+The optional "Resource Source Index" and "Resource Source" fields
+were ignored.
+
+
+----------------------------------------
+22 November 2002.  Summary of changes for version 20021122.
+
+
+1) ACPI CA Core Subsystem:
+
+Fixed a reported problem where an object stored to a Method Local
+or Arg was not copied to a new object during the store - the
+object pointer was simply copied to the Local/Arg.  This caused
+all subsequent operations on the Local/Arg to also affect the
+original source of the store operation.
+
+Fixed a problem where a store operation to a Method Local or Arg
+was not completed properly if the Local/Arg contained a reference
+(from RefOf) to a named field.  The general-purpose store-to-
+namespace-node code is now used so that this case is handled
+automatically.
+
+Fixed a problem where the internal object copy routine would cause
+a protection fault if the object being copied was a Package and
+contained either 1) a NULL package element or 2) a nested sub-
+package.
+
+Fixed a problem with the GPE initialization that resulted from an
+ambiguity in the ACPI specification.  One section of the
+specification states that both the address and length of the GPE
+block must be zero if the block is not supported.  Another section
+implies that only the address need be zero if the block is not
+supported.  The code has been changed so that both the address and
+the length must be non-zero to indicate a valid GPE block (i.e.,
+if either the address or the length is zero, the GPE block is
+invalid.)
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+2) Linux
+
+Cleaned up EC driver. Exported an external EC read/write
+interface. By going through this, other drivers (most notably
+sonypi) will be able to serialize access to the EC.
+
+
+3) iASL Compiler/Disassembler
+
+Implemented support to optionally generate include files for both
+ASM and C (the -i switch).  This simplifies BIOS development by
+automatically creating include files that contain external
+declarations for the symbols that are created within the
+
+(optionally generated) ASM and C AML source files.
+
+
+----------------------------------------
+15 November 2002.  Summary of changes for version 20021115.
+
+1) ACPI CA Core Subsystem:
+
+Fixed a memory leak problem where an error during resolution of
+
+method arguments during a method invocation from another method
+failed to cleanup properly by deleting all successfully resolved
+argument objects.
+
+Fixed a problem where the target of the Index() operator was not
+correctly constructed if the source object was a package.  This
+problem has not been detected because the use of a target operand
+with Index() is very rare.
+
+Fixed a problem with the Index() operator where an attempt was
+made to delete the operand objects twice.
+
+Fixed a problem where an attempt was made to delete an operand
+twice during execution of the CondRefOf() operator if the target
+did not exist.
+
+Implemented the first of perhaps several internal create object
+functions that create and initialize a specific object type.  This
+consolidates duplicated code wherever the object is created, thus
+shrinking the size of the subsystem.
+
+Implemented improved debug/error messages for errors that occur
+during nested method invocations.  All executing method pathnames
+are displayed (with the error) as the call stack is unwound - thus
+simplifying debug.
+
+Fixed a problem introduced in the 10/02 release that caused
+premature deletion of a buffer object if a buffer was used as an
+ASL operand where an integer operand is required (Thus causing an
+implicit object conversion from Buffer to Integer.)  The change in
+the 10/02 release was attempting to fix a memory leak (albeit
+incorrectly.)

+
+Changed the implementation of the ACPI semaphores to use down()
+instead of down_interruptable().  It is important that the
+execution of ACPI control methods not be interrupted by signals.
+Methods must run to completion, or the system may be left in an
+unknown/unstable state.
+
+Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not set.

+
+3) iASL Compiler/Disassembler
+
+
+Changed the default location of output files.  All output files
+are now placed in the current directory by default instead of in
+the directory of the source file.  This change may affect some
+existing makefiles, but it brings the behavior of the compiler in
+line with other similar tools.  The location of the output files
+can be overridden with the -p command line switch.

+11 November 2002.  Summary of changes for version 20021111.
+
+
+0) ACPI Specification 2.0B is released and is now available at:
+http://www.acpi.info/index.html
+
+
+1) ACPI CA Core Subsystem:
+
+Implemented support for the ACPI 2.0 SMBus Operation Regions.
+This includes the early detection and handoff of the request to
+the SMBus region handler (avoiding all of the complex field
+support code), and support for the bidirectional return packet
+from an SMBus write operation.  This paves the way for the
+development of SMBus drivers in each host operating system.
+
+Fixed a problem where the semaphore WAIT_FOREVER constant was
+defined as 32 bits, but must be 16 bits according to the ACPI
+specification.  This had the side effect of causing ASL
+Mutex/Event timeouts even though the ASL code requested a wait
+forever.  Changed all internal references to the ACPI timeout
+parameter to 16 bits to prevent future problems.  Changed the name
+of WAIT_FOREVER to ACPI_WAIT_FOREVER.
+
+Code and Data Size: Current core subsystem library sizes are shown

+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+2) Linux
+
+Module loading/unloading fixes (John Cagle)
+
+
+3) iASL Compiler/Disassembler
+
+Added support for the SMBBlockProcessCall keyword (ACPI 2.0)
+
+Implemented support for the disassembly of all SMBus protocol
+keywords (SMBQuick, SMBWord, etc.)
+
+----------------------------------------
+01 November 2002.  Summary of changes for version 20021101.
+
+
+1) ACPI CA Core Subsystem:
+
+Fixed a problem where platforms that have a GPE1 block but no GPE0
+block were not handled correctly.  This resulted in a "GPE
+overlap" error message.  GPE0 is no longer required.
+
+Removed code added in the previous release that inserted nodes
+into the namespace in alphabetical order.  This caused some side-
+effects on various machines.  The root cause of the problem is
+still under investigation since in theory, the internal ordering
+of the namespace nodes should not matter.
+
+
+Enhanced error reporting for the case where a named object is not
+found during control method execution.  The full ACPI namepath
+(name reference) of the object that was not found is displayed in
+this case.
+
+Note: as a result of the overhaul of the namespace object types in
+the previous release, the namespace nodes for the predefined
+scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE
+instead of ACPI_TYPE_ANY.  This simplifies the namespace
+management code but may affect code that walks the namespace tree
+looking for specific object types.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a much larger code and data size.  Note that these values will
+vary depending on the efficiency of the compiler and the compiler
+options used during generation.
+
+  Previous Release
+    Non-Debug Version:  70.7K Code,   8.6K Data,   79.3K Total
+    Debug Version:     151.7K Code,  62.4K Data,  214.1K Total
+  Current Release:
+    Non-Debug Version:  71.4K Code,   9.0K Data,   80.4K Total
+    Debug Version:     152.3K Code,  63.0K Data,  215.3K Total
+
+
+2) Linux
+
+Fixed a problem introduced in the previous release where the
+Processor and Thermal objects were not recognized and installed in
+/proc.  This was related to the scope type change described above.
+
+
+3) iASL Compiler/Disassembler
+
+Implemented the -g option to get all of the required ACPI tables
+from the registry and save them to files (Windows version of the
+compiler only.)  The required tables are the FADT, FACS, and DSDT.
+
+Added ACPI table checksum validation during table disassembly in
+order to catch corrupted tables.
+
+
+----------------------------------------
+22 October 2002.  Summary of changes for version 20021022.
+
+1) ACPI CA Core Subsystem:
+
+Implemented a restriction on the Scope operator that the target
+must already exist in the namespace at the time the operator is
+encountered (during table load or method execution).  In other
+words, forward references are not allowed and Scope() cannot
+create a new object. This changes the previous behavior where the
+interpreter would create the name if not found.  This new behavior
+correctly enables the search-to-root algorithm during namespace
+lookup of the target name.  Because of this upsearch, this fixes
+the known Compaq _SB_.OKEC problem and makes both the AML
+interpreter and iASL compiler compatible with other ACPI
+implementations.
+
+Completed a major overhaul of the internal ACPI object types for
+the ACPI Namespace and the associated operand objects.  Many of
+these types had become obsolete with the introduction of the two-
+pass namespace load.  This cleanup simplifies the code and makes
+the entire namespace load mechanism much clearer and easier to
+understand.
+
+Improved debug output for tracking scope opening/closing to help
+diagnose scoping issues.  The old scope name as well as the new
+scope name are displayed.  Also improved error messages for
+problems with ASL Mutex objects and error messages for GPE
+problems.
+
+Cleaned up the namespace dump code, removed obsolete code.
+
+All string output (for all namespace/object dumps) now uses the
+common ACPI string output procedure which handles escapes properly
+and does not emit non-printable characters.
+
+Fixed some issues with constants in the 64-bit version of the
+local C library (utclib.c)
+
+
+2) Linux
+
+EC Driver:  No longer attempts to acquire the Global Lock at
+interrupt level.
+
+
+3) iASL Compiler/Disassembler
+
+Implemented ACPI 2.0B grammar change that disallows all Type 1 and
+2 opcodes outside of a control method.  This means that the
+"executable" operators (versus the "namespace" operators) cannot
+be used at the table level; they can only be used within a control
+method.
+
+Implemented the restriction on the Scope() operator where the
+target must already exist in the namespace at the time the
+operator is encountered (during ASL compilation). In other words,
+forward references are not allowed and Scope() cannot create a new
+object.  This makes the iASL compiler compatible with other ACPI
+implementations and makes the Scope() implementation adhere to the
+ACPI specification.
+
+Fixed a problem where namepath optimization for the Alias operator
+was optimizing the wrong path (of the two namepaths.)  This caused
+a "Missing alias link" error message.
+
+Fixed a problem where an "unknown reserved name" warning could be
+incorrectly generated for names like "_SB" when the trailing
+underscore is not used in the original ASL.
+
+Fixed a problem where the reserved name check did not handle
+NamePaths with multiple NameSegs correctly.  The first nameseg of
+the NamePath was examined instead of the last NameSeg.
+
+
+----------------------------------------
+
+02 October 2002.  Summary of changes for this release.
+
+
+1) ACPI CA Core Subsystem version 20021002:
+
+Fixed a problem where a store/copy of a string to an existing
+string did not always set the string length properly in the String
+object.
+
+Fixed a reported problem with the ToString operator where the
+behavior was identical to the ToHexString operator instead of just
+simply converting a raw buffer to a string data type.
+
+Fixed a problem where CopyObject and the other "explicit"
+conversion operators were not updating the internal namespace node
+type as part of the store operation.
+
+Fixed a memory leak during implicit source operand conversion
+where the original object was not deleted if it was converted to a
+new object of a different type.
+
+Enhanced error messages for all problems associated with namespace
+lookups.  Common procedure generates and prints the lookup name as
+well as the formatted status.
+
+Completed implementation of a new design for the Alias support
+within the namespace.  The existing design did not handle the case
+where a new object was assigned to one of the two names due to the
+use of an explicit conversion operator, resulting in the two names
+pointing to two different objects.  The new design simply points
+the Alias name to the original name node - not to the object.
+This results in a level of indirection that must be handled in the
+name resolution mechanism.
+
+Code and Data Size: Current core subsystem library sizes are shown
+below.  These are the code and data sizes for the acpica.lib
+produced by the Microsoft Visual C++ 6.0 compiler, and these
+values do not include any ACPI driver or OSPM code.  The debug
+version of the code includes the debug output trace mechanism and
+has a larger code and data size.  Note that these values will vary
+depending on the efficiency of the compiler and the compiler
+options used during generation.

+
+
+----------------------------------------
+18 September 2002.  Summary of changes for this release.
+
+
+1) ACPI CA Core Subsystem version 20020918:
+
+Fixed a reported problem with reference chaining (via the Index()
+and RefOf() operators) in the ObjectType() and SizeOf() operators.
+The definition of these operators includes the dereferencing of
+all chained references to return information on the base object.
+
+Fixed a problem with stores to indexed package elements - the
+existing code would not complete the store if an "implicit
+conversion" was not performed.  In other words, if the existing
+object (package element) was to be replaced completely, the code
+didn't handle this case.
+
+Relaxed typechecking on the ASL "Scope" operator to allow the
+target name to refer to an object of type Integer, String, or
+Buffer, in addition to the scoping object types (Device,
+predefined Scopes, Processor, PowerResource, and ThermalZone.)
+This allows existing AML code that has workarounds for a bug in
+Windows to function properly.  A warning is issued, however.  This
+affects both the AML interpreter and the iASL compiler. Below is
+an example of this type of ASL code:
+
+      Name(DEB,0x00)
+      Scope(DEB)
+      {
+
+Fixed some reported problems with 64-bit integer support in the
+local implementation of C library functions (clib.c)
+
+
+2) Linux
+
+Use ACPI fix map region instead of IOAPIC region, since it is
+undefined in non-SMP.
+
+Ensure that the SCI has the proper polarity and trigger, even on
+systems that do not have an interrupt override entry in the MADT.
+
+2.5 big driver reorganization (Pat Mochel)
+
+Use early table mapping code from acpitable.c (Andi Kleen)
+
+New blacklist entries (Andi Kleen)
+
+Blacklist improvements. Split blacklist code out into a separate
+file. Move checking the blacklist to very early. Previously, we
+would use ACPI tables, and then halfway through init, check the
+blacklist -- too late. Now, it's early enough to completely fall-
+back to non-ACPI.
+
+
+3) iASL Compiler/Disassembler version 20020918:
+
+Fixed a problem where the typechecking code didn't know that an
+alias could point to a method.  In other words, aliases were not
+being dereferenced during typechecking.
+
+
+----------------------------------------
+29 August 2002.  Summary of changes for this release.
+
+1) ACPI CA Core Subsystem Version 20020829:
+
+If the target of a Scope() operator already exists, it must be an
+object type that actually opens a scope -- such as a Device,
+Method, Scope, etc.  This is a fatal runtime error.  Similar error
+check has been added to the iASL compiler also.
+
+Tightened up the namespace load to disallow multiple names in the
+same scope.  This previously was allowed if both objects were of
+the same type.  (i.e., a lookup was the same as entering a new
+name).
+
+
+2) Linux
+
+Ensure that the ACPI interrupt has the proper trigger and
+polarity.
+
+local_irq_disable is extraneous. (Matthew Wilcox)
+
+Make "acpi=off" actually do what it says, and not use the ACPI
