Summary of changes for version 20120420: + +This release is available at www.acpica.org/downloads. +The ACPI 5.0 specification is available at www.acpi.info. + +1) ACPICA Core Subsystem: + +Implemented support for multiple notify handlers. This change adds support to +allow multiple system and device notify handlers on Device, Thermal Zone, and +Processor objects. This can simplify the host OS notification implementation. +Also re-worked and restructured the entire notify support code to simplify +handler installation, handler removal, notify event queuing, and notify +dispatch to handler(s). Note: there can still only be two global notify +handlers - one for system notifies and one for device notifies. There are no +changes to the existing handler install/remove interfaces. Lin Ming, Bob +Moore, Rafael Wysocki. + +Fixed a regression in the package repair code where the object reference +count was calculated incorrectly. Regression was introduced in the commit +"Support to add Package wrappers". + +Fixed a couple possible memory leaks in the AML parser, in the error recovery +path. Jesper Juhl, Lin Ming. + +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: 92.9K Code, 25.0K Data, 117.9K Total + Debug Version: 172.5K Code, 73.2K Data, 245.7K Total + Current Release: + Non-Debug Version: 92.9K Code, 25.0K Data, 117.9K Total + Debug Version: 172.6K Code, 73.4K Data, 246.0K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Fixed a problem with the resource descriptor support where the length +of the StartDependentFn and StartDependentFnNoPrio descriptors were not +included in cumulative descriptor offset, resulting in incorrect values for +resource tags within resource descriptors appearing after a StartDependent* +descriptor. Reported by Petr Vandrovec. ACPICA BZ 949. + +iASL and Preprocessor: Implemented full support for the #line directive to +correctly track original source file line numbers through the .i preprocessor +output file - for error and warning messages. + +iASL: Expand the allowable byte constants for address space IDs. Previously, +the allowable range was 0x80-0xFF (user-defined spaces), now the range is +0x0A-0xFF to allow for custom and new IDs without changing the compiler. + +iASL: Add option to treat all warnings as errors (-we). ACPICA BZ 948. + +iASL: Add option to completely disable the preprocessor (-Pn). + +iASL: Now emit all error/warning messages to standard error (stderr) by +default (instead of the previous stdout). + +ASL Test Suite (ASLTS): Reduce iASL warnings due to use of Switch(). Update +for resource descriptor offset fix above. Update/cleanup error output +routines. Enable and send iASL errors/warnings to an error logfile +(error.txt). Send all other iASL output to a logfile (compiler.txt). Fixed +several extraneous "unrecognized operator" messages. + +---------------------------------------- 20 March 2012.
