14 November 2012. 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<method> 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This command was out-of-date and did not properly disassemble control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.
