Summary of changes for version 20120518: + + +1) ACPICA Core Subsystem: + +Added a new OSL interface, AcpiOsWaitEventsComplete. This interface is defined +to block until asynchronous events such as notifies and GPEs have completed. +Within ACPICA, it is only called before a notify or GPE handler is +removed/uninstalled. It also may be useful for the host OS within related +drivers such as the Embedded Controller driver. See the ACPICA reference for +additional information. ACPICA BZ 868. + +ACPI Tables: Added a new error message for a possible overflow failure during +the conversion of FADT 32-bit legacy register addresses to internal common 64- +bit GAS structure representation. The GAS has a one-byte "bit length" field, +thus limiting the register length to 255 bits. ACPICA BZ 953. + +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: 172.6K Code, 73.4K Data, 246.0K Total + Current Release: + Non-Debug Version: 93.0K Code, 25.1K Data, 118.1K Total + Debug Version: 172.7K Code, 73.6K Data, 246.3K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Added the ACPI 5.0 "PCC" keyword for use in the Register() ASL macro. +This keyword was added late in the ACPI 5.0 release cycle and was not +implemented until now. + +Disassembler: Added support for Operation Region externals. Adds missing +support for operation regions that are defined in another table, and +referenced locally via a Field or BankField ASL operator. Now generates the +correct External statement. + +Disassembler: Several additional fixes for the External() statement generation +related to some ASL operators. Also, order the External() statements +alphabetically in the disassembler output. Fixes the External() generation for +the Create* field, Alias, and Scope operators: + 1) Create* buffer field operators - fix type mismatch warning on disassembly + 2) Alias - implement missing External support + 3) Scope - fix to make sure all necessary externals are emitted. + +iASL: Improved pathname support. For include files, merge the prefix pathname +with the file pathname and eliminate unnecessary components. Convert +backslashes in all pathnames to forward slashes, for readability. Include file +pathname changes affect both #include and Include() type operators. + +iASL/DTC/Preprocessor: Gracefully handle early EOF. Handle an EOF at the end +of a valid line by inserting a newline and then returning the EOF during the +next call to GetNextLine. Prevents the line from being ignored due to EOF +condition. + +iASL: Implemented some changes to enhance the IDE support (-vi option.) Error +and Warning messages are now correctly recognized for both the source code +browser and the global error and warning counts. + +---------------------------------------- 20 April 2012.
