Summary of changes for version 20130418: +17 May 2013. Summary of changes for version 20130517: + +1) ACPICA kernel-resident subsystem: -This release is available at https://acpica.org/downloads +Fixed a regression introduced in version 20130328 for _INI methods. This +change fixes a problem introduced in 20130328 where _INI methods are no +longer executed properly because of a memory block that was not +initialized correctly. ACPICA BZ 1016. Tomasz Nowicki +<tomasz.nowicki@linaro.org>. + +Fixed a possible problem with the new extended sleep registers in the ACPI +5.0 FADT. Do not use these registers (even if populated) unless the HW- +reduced bit is set in the FADT (as per the ACPI specification). ACPICA BZ +1020. Lv Zheng. + +Implemented return value repair code for _CST predefined objects: Sort the +list and detect/remove invalid entries. ACPICA BZ 890. Lv Zheng. + +Implemented a debug-only option to disable loading of SSDTs from the +RSDT/XSDT during ACPICA initialization. This can be useful for debugging +ACPI problems on some machines. Set AcpiGbl_DisableSsdtTableLoad in +acglobal.h - ACPICA BZ 1005. Lv Zheng. + +Fixed some issues in the ACPICA initialization and termination code: +Tomasz Nowicki <tomasz.nowicki@linaro.org> +1) Clear events initialized flag upon event component termination. ACPICA +BZ 1013. +2) Fixed a possible memory leak in GPE init error path. ACPICA BZ 1018. +3) Delete global lock pending lock during termination. ACPICA BZ 1012. +4) Clear debug buffer global on termination to prevent possible multiple +delete. ACPICA BZ 1010. + +Standardized all switch() blocks across the entire source base. After many +years, different formatting for switch() had crept in. This change makes +the formatting of every switch block identical. ACPICA BZ 997. Chao Guan. + +Split some files to enhance ACPICA modularity and configurability: +1) Split buffer dump routines into utilities/utbuffer.c +2) Split internal error message routines into utilities/uterror.c +3) Split table print utilities into tables/tbprint.c +4) Split iASL command-line option processing into asloptions.c + +Makefile enhancements: +1) Support for all new files above. +2) Abort make on errors from any subcomponent. Chao Guan. +3) Add build support for Apple Mac OS X. Liang Qi. + +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. + Current Release: + Non-Debug Version: 96.0K Code, 27.0K Data, 123.0K Total + Debug Version: 184.1K Code, 76.8K Data, 260.9K Total + Previous Release: + Non-Debug Version: 95.6K Code, 26.8K Data, 122.4K Total + Debug Version: 183.5K Code, 76.6K Data, 260.1K Total + + +2) iASL Compiler/Disassembler and Tools: + +New utility: Implemented an easily portable version of the acpidump +utility to extract ACPI tables from the system (or a file) in an ASCII hex +dump format. The top-level code implements the various command line +options, file I/O, and table dump routines. To port to a new host, only +three functions need to be implemented to get tables -- since this +functionality is OS-dependent. See the tools/acpidump/apmain.c module and +the ACPICA reference for porting instructions. ACPICA BZ 859. Notes: +1) The Windows version obtains the ACPI tables from the Registry. +2) The Linux version is under development. +3) Other hosts - If an OS-dependent module is submitted, it will be +distributed with ACPICA. + +iASL: Fixed a regression for -D preprocessor option (define symbol). A +restructuring/change to the initialization sequence caused this option to +no longer work properly. + +iASL: Implemented a mechanism to disable specific warnings and remarks. +Adds a new command line option, "-vw <messageid> as well as "#pragma +disable <messageid>". ACPICA BZ 989. Chao Guan, Bob Moore. + +iASL: Fix for too-strict package object validation. The package object +validation for return values from the predefined names is a bit too +strict, it does not allow names references within the package (which will +be resolved at runtime.) These types of references cannot be validated at +compile time. This change ignores named references within package objects +for names that return or define static packages. + +Debugger: Fixed the 80-character command line limitation for the History +command. Now allows lines of arbitrary length. ACPICA BZ 1000. Chao Guan. + +iASL: Added control method and package support for the -so option +(generates AML offset table for BIOS support.) + +iASL: issue a remark if a non-serialized method creates named objects. If +a thread blocks within the method for any reason, and another thread +enters the method, the method will fail because an attempt will be made to +create the same (named) object twice. In this case, issue a remark that +the method should be marked serialized. NOTE: may become a warning later. +ACPICA BZ 909. + +---------------------------------------- +18 April 2013.
