---------------------------------------- 17 July 2015. Summary of changes for version 20150717: 1) ACPICA kernel-resident subsystem: Improved the partitioning between the Debugger and Disassembler components. This allows the Debugger to be used standalone within kernel code without the Disassembler (which is used for single stepping also). This renames and moves one file, dmobject.c to dbobject.c. Lv Zheng. Debugger: Implemented a new command to trace the execution of control methods (Trace). This is especially useful for the in-kernel version of the debugger when file I/O may not be available for method trace output. See the ACPICA reference for more information. Lv Zheng. Moved all C library prototypes (used for the local versions of these functions when requested) to a new header, acclib.h Cleaned up the use of non-ANSI C library functions. These functions are implemented locally in ACPICA. Moved all such functions to a common source file, utnonansi.c Debugger: Fixed a problem with the "!!" command (get last command executed) where the debugger could enter an infinite loop and eventually crash. Removed the use of local macros that were used for some of the standard C library functions to automatically cast input parameters. This mostly affected the is* functions where the input parameter is defined to be an int. This required a few modifications to the main ACPICA source code to provide casting for these functions and eliminate possible compiler warnings for these parameters. Across the source code, added additional status/error checking to resolve issues discovered by static source code analysis tools such as Coverity. Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size. Current Release: Non-Debug Version: 100.9K Code, 24.5K Data, 125.4K Total Debug Version: 197.8K Code, 81.5K Data, 279.3K Total Previous Release: Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total Debug Version: 196.2K Code, 81.0K Data, 277.2K Total 2) iASL Compiler/Disassembler and Tools: iASL: Fixed a regression where the device map file feature no longer worked properly when used in conjunction with the disassembler. It only worked properly with the compiler itself. iASL: Implemented a new warning for method LocalX variables that are set but never used (similar to a C compiler such as gcc). This also applies to ArgX variables that are not defined by the parent method, and are instead (legally) used as local variables. iASL/Preprocessor: Finished the pass-through of line numbers from the preprocessor to the compiler. This ensures that compiler errors/warnings have the correct original line numbers and filenames, regardless of any #include files. iASL/Preprocessor: Fixed a couple of issues with comment handling and the pass-through of comments to the preprocessor output file (which becomes the compiler input file). Also fixed a problem with // comments that appear after a math expression. iASL: Added support for the TCPA server table to the table compiler and template generator. (The client table was already previously supported) iASL/Preprocessor: Added a permanent #define of the symbol "__IASL__" to identify the iASL compiler. Cleaned up the use of the macros NEGATIVE and POSITIVE which were defined multiple times. The new names are ACPI_SIGN_NEGATIVE and ACPI_SIGN_POSITIVE. AcpiHelp: Update to expand help messages for the iASL preprocessor directives. ---------------------------------------- 19 June 2015. Summary of changes for version 20150619: Two regressions in version 20150616 have been addressed: Fixes some problems/issues with the C library macro removal (ACPI_STRLEN, etc.) This update changes ACPICA to only use the standard headers for functions, or the prototypes for the local versions of the C library functions. Across the source code, this required some additional casts for some Clib invocations for portability. Moved all local prototypes to a new file, acclib.h Fixes several problems with recent changes to the handling of the FACS table that could cause some systems not to boot. ---------------------------------------- 16 June 2015. Summary of changes for version 20150616: 1) ACPICA kernel-resident subsystem: Across the entire ACPICA source code base, the various macros for the C library functions (such as ACPI_STRLEN, etc.) have been removed and replaced by the standard C library names (strlen, etc.) The original purpose for these macros is no longer applicable. This simplification reduces the number of macros used in the ACPICA source code significantly, improving readability and maintainability. Implemented support for a new ACPI table, the OSDT. This table, the "override" SDT, can be loaded directly by the host OS at boot time. It enables the replacement of existing namespace objects that were installed via the DSDT and/or SSDTs. The primary purpose for this is to replace buggy or incorrect ASL/AML code obtained via the BIOS. The OSDT is slated for inclusion in a future version of the ACPI Specification. Lv Zheng/Bob Moore. Added support for systems with (improperly) two FACS tables -- a "32-bit" table (via FADT 32-bit legacy field) and a "64-bit" table (via the 64-bit X field). This change will support both automatically. There continues to be systems found with this issue. This support requires a change to the AcpiSetFirmwareWakingVector interface. Also, a public global variable has been added to allow the host to select which FACS is desired (AcpiGbl_Use32BitFacsAddresses). See the ACPICA reference for more details Lv Zheng. Added a new feature to allow for systems that do not contain an FACS. Although this is already supported on hardware-reduced platforms, the feature has been extended for all platforms. The reasoning is that we do not want to abort the entire ACPICA initialization just because the system is seriously buggy and has no FACS. Fixed a problem where the GUID strings for NFIT tables (in acuuid.h) were not correctly transcribed from the ACPI specification in ACPICA version 20150515. Implemented support for the _CLS object in the AcpiGetObjectInfo external interface. Updated the definitions of the TCPA and TPM2 ACPI tables to the more recent TCG ACPI Specification, December 14, 2014. Table disassembler and compiler also updated. Note: The TCPA "server" table is not supported by the disassembler/table-compiler at this time. ACPI 6.0: Added definitions for the new GIC version field in the MADT. Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size. Current Release: Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total Debug Version: 196.2K Code, 81.0K Data, 277.2K Total Previous Release: Non-Debug Version: 99.9K Code, 27.5K Data, 127.4K Total Debug Version: 195.2K Code, 80.8K Data, 276.0K Total 2) iASL Compiler/Disassembler and Tools: Disassembler: Fixed a problem with the new symbolic operator disassembler where incorrect ASL code could be emitted in some cases for the "non- commutative" operators -- Subtract, Divide, Modulo, ShiftLeft, and ShiftRight. The actual problem cases seem to be rather unusual in common ASL code, however. David Box. Modified the linux version of acpidump to obtain ACPI tables from not just /dev/mem (which may not exist) and /sys/firmware/acpi/tables. Lv Zheng. iASL: Fixed a problem where the user preprocessor output file (.i) contained extra data that was not expected. The compiler was using this file as a temporary file and passed through #line directives in order to keep compiler error messages in sync with the input file and line number across multiple include files. The (.i) is no longer a temporary file as the compiler uses a new, different file for the original purpose. iASL: Fixed a problem where comments within the original ASL source code file were not passed through to the preprocessor output file, nor any listing files. iASL: Fixed some issues for the handling of the "#include" preprocessor directive and the similar (but not the same) "Include" ASL operator. iASL: Add support for the new OSDT in both the disassembler and compiler. iASL: Fixed a problem with the constant folding support where a Buffer object could be incorrectly generated (incorrectly formed) during a conversion to a Store() operator. AcpiHelp: Updated for new NFIT GUIDs, "External" AML opcode, and new description text for the _REV predefined name. _REV now permanently returns 2, as per the ACPI 6.0 specification. Debugger: Enhanced the output of the Debug ASL object for references produced by the Index operator. For Buffers and strings, only output the actual byte pointed to by the index. For packages, only print the single package element decoded by the index. Previously, the entire buffer/string/package was emitted. iASL/Table-compiler: Fixed a regression where the "generic" data types were no longer recognized, causing errors. ---------------------------------------- 15 May 2015. Summary of changes for version 20150515: This release implements most of ACPI 6.0 as described below. 1) ACPICA kernel-resident subsystem: Implemented runtime argument checking and return value checking for all new ACPI 6.0 predefined names. This includes: _BTH, _CR3, _DSD, _LPI, _MTL, _PRR, _RDI, _RST, _TFP, _TSN. Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size. Current Release: Non-Debug Version: 99.9K Code, 27.5K Data, 127.4K Total Debug Version: 195.2K Code, 80.8K Data, 276.0K Total Previous Release: Non-Debug Version: 99.1K Code, 27.3K Data, 126.4K Total Debug Version: 192.8K Code, 79.9K Data, 272.7K Total 2) iASL Compiler/Disassembler and Tools: iASL compiler: Added compile-time support for all new ACPI 6.0 predefined names (argument count validation and return value typechecking.) iASL disassembler and table compiler: implemented support for all new ACPI 6.0 tables. This includes: DRTM, IORT, LPIT, NFIT, STAO, WPBT, XENV. iASL disassembler and table compiler: Added ACPI 6.0 changes to existing tables: FADT, MADT. iASL preprocessor: Added a new directive to enable inclusion of binary blobs into ASL code. The new directive is #includebuffer. It takes a binary file as input and emits a named ascii buffer object into the ASL code. AcpiHelp: Added support for all new ACPI 6.0 predefined names. AcpiHelp: Added a new option, -d, to display all iASL preprocessor directives. AcpiHelp: Added a new option, -t, to display all known/supported ACPI tables.
