----------------------------------------
|
||||
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.
