Summary of changes for version 20140424: + +1) ACPICA kernel-resident subsystem: + +Implemented support to skip/ignore NULL address entries in the RSDT/XSDT. +Some of these tables are known to contain a trailing NULL entry. Lv +Zheng. + +Removed an extraneous error message for the case where there are a large +number of system GPEs (> 124). This was the "32-bit FADT register is too +long to convert to GAS struct" message, which is irrelevant for GPEs +since the GPEx_BLK_LEN fields of the FADT are always used instead of the +(limited capacity) GAS bit length. Also, several changes to ensure proper +support for GPE numbers > 255, where some "GPE number" fields were 8-bits +internally. + +Implemented and deployed additional configuration support for the public +ACPICA external interfaces. Entire classes of interfaces can now be +easily modified or configured out, replaced by stubbed inline functions +by default. Lv Zheng. + +Moved all public ACPICA runtime configuration globals to the public +ACPICA external interface file for convenience. Also, removed some +obsolete/unused globals. See the file acpixf.h. Lv Zheng. + +Documentation: Added a new section to the ACPICA reference describing the +maximum number of GPEs that can be supported by the FADT-defined GPEs in +block zero and one. About 1200 total. See section 4.4.1 of the ACPICA +reference. + +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: 96.8K Code, 27.2K Data, 124.0K Total + Debug Version: 189.5K Code, 79.7K Data, 269.2K Total + Previous Release: + Non-Debug Version: 97.0K Code, 27.2K Data, 124.2K Total + Debug Version: 189.7K Code, 79.5K Data, 269.2K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL and disassembler: Add full support for the LPIT table (Low Power +Idle Table). Includes support in the disassembler, data table compiler, +and template generator. + +AcpiDump utility: +1) Add option to force the use of the RSDT (over the XSDT). +2) Improve validation of the RSDP signature (use 8 chars instead of 4). + +iASL: Add check for predefined packages that are too large. For +predefined names that contain subpackages, check if each subpackage is +too large. (Check for too small already exists.) + +Debugger: Updated the GPE command (which simulates a GPE by executing the +GPE code paths in ACPICA). The GPE device is now optional, and defaults +to the GPE 0/1 FADT-defined blocks. + +Unix application OSL: Update line-editing support. Add additional error +checking and take care not to reset terminal attributes on exit if they +were never set. This should help guarantee that the terminal is always +left in the previous state on program exit. + +---------------------------------------- 25 March 2014.
