Summary of changes for version 20121114: + +This release is available at https://www.acpica.org/downloads +The ACPI 5.0 specification is available at www.acpi.info + +1) ACPICA Kernel-resident Subsystem: + +Implemented a performance enhancement for ACPI/AML Package objects. This +change greatly increases the performance of Package objects within the +interpreter. It changes the processing of reference counts for packages by +optimizing for the most common case where the package sub-objects are +either Integers, Strings, or Buffers. Increases the overall performance of +the ASLTS test suite by 1.5X (Increases the Slack Mode performance by 2X.) +Chao Guan. ACPICA BZ 943. + +Implemented and deployed common macros to extract flag bits from resource +descriptors. Improves readability and maintainability of the code. Fixes a +problem with the UART serial bus descriptor for the number of data bits +flags (was incorrectly 2 bits, should be 3). + +Enhanced the ACPI_GETx and ACPI_SETx macros. Improved the implementation +of the macros and changed the SETx macros to the style of (destination, +source). Also added ACPI_CASTx companion macros. Lv Zheng. + +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. + + Previous Release: + Non-Debug Version: 93.9K Code, 25.2K Data, 119.1K Total + Debug Version: 175.5K Code, 74.5K Data, 250.0K Total + Current Release: + Non-Debug Version: 94.3K Code, 25.3K Data, 119.6K Total + Debug Version: 175.5K Code, 74.5K Data, 250.0K Total + + +2) iASL Compiler/Disassembler and Tools: + +Disassembler: Added the new ACPI 5.0 interrupt sharing flags. This change +adds the ShareAndWake and ExclusiveAndWake flags which were added to the +Irq, Interrupt, and Gpio resource descriptors in ACPI 5.0. ACPICA BZ 986. + +Disassembler: Fixed a problem with external declaration generation. Fixes +a problem where an incorrect pathname could be generated for an external +declaration if the original reference to the object includes leading +carats (^). ACPICA BZ 984. + +Debugger: Completed a major update for the Disassemble command. +This command was out-of-date and did not properly disassemble control +methods that had any reasonable complexity. This fix brings the command up +to the same level as the rest of the disassembler. Adds one new file, +dmdeferred.c, which is existing code that is now common with the main +disassembler and the debugger disassemble command. ACPICA MZ 978. + +iASL: Moved the parser entry prototype to avoid a duplicate declaration. +Newer versions of Bison emit this prototype, so moved the prototype out of +the iASL header to where it is actually used in order to avoid a duplicate +declaration. + +iASL/Tools: Standardized use of the stream I/O functions: + 1) Ensure check for I/O error after every fopen/fread/fwrite + 2) Ensure proper order of size/count arguments for fread/fwrite + 3) Use test of (Actual != Requested) after all fwrite, and most fread + 4) Standardize I/O error messages +Improves reliability and maintainability of the code. Bob Moore, Lv Zheng. +ACPICA BZ 981. + +Disassembler: Prevent duplicate External() statements. During generation +of external statements, detect similar pathnames that are actually +duplicates such as these: + External (\ABCD) + External (ABCD) +Remove all leading '\' characters from pathnames during the external +statement generation so that duplicates will be detected and tossed. +ACPICA BZ 985. + +Tools: Replace low-level I/O with stream I/O functions. Replace +open/read/write/close with the stream I/O equivalents +fopen/fread/fwrite/fclose for portability and performance. Lv Zheng, Bob +Moore. + +AcpiBin: Fix for the dump-to-hex function. Now correctly output the table +name header so that AcpiXtract recognizes the output file/table. + +iASL: Remove obsolete -2 option flag. Originally intended to force the +compiler/disassembler into an ACPI 2.0 mode, this was never implemented +and the entire concept is now obsolete. + ---------------------------------------- 18 October 2012.
