Summary of changes for version 20130823: + +1) ACPICA kernel-resident subsystem: + +Implemented support for host-installed System Control Interrupt (SCI) +handlers. Certain ACPI functionality requires the host to handle raw +SCIs. For example, the "SCI Doorbell" that is defined for memory power +state support requires the host device driver to handle SCIs to examine +if the doorbell has been activated. Multiple SCI handlers can be +installed to allow for future expansion. New external interfaces are +AcpiInstallSciHandler, AcpiRemoveSciHandler; see the ACPICA reference for +details. Lv Zheng, Bob Moore. ACPICA BZ 1032. + +Operation region support: Never locally free the handler "context" +pointer. This change removes some dangerous code that attempts to free +the handler context pointer in some (rare) circumstances. The owner of +the handler owns this pointer and the ACPICA code should never touch it. +Although not seen to be an issue in any kernel, it did show up as a +problem (fault) under AcpiExec. Also, set the internal storage field for +the context pointer to zero when the region is deactivated, simply for +sanity. David Box. ACPICA BZ 1039. + +AcpiRead: On error, do not modify the return value target location. If an +error happens in the middle of a split 32/32 64-bit I/O operation, do not +modify the target of the return value pointer. Makes the code consistent +with the rest of ACPICA. Bjorn Helgaas. + +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: 96.7K Code, 27.1K Data, 123.9K Total + Debug Version: 184.4K Code, 76.8K Data, 261.2K Total + Previous Release: + Non-Debug Version: 96.2K Code, 27.1K Data, 123.3K Total + Debug Version: 185.4K Code, 77.1K Data, 262.5K Total + + +2) iASL Compiler/Disassembler and Tools: + +AcpiDump: Implemented several new features and fixed some problems: +1) Added support to dump the RSDP, RSDT, and XSDT tables. +2) Added support for multiple table instances (SSDT, UEFI). +3) Added option to dump "customized" (overridden) tables (-c). +4) Fixed a problem where some table filenames were improperly +constructed. +5) Improved some error messages, removed some unnecessary messages. + +iASL: Implemented additional support for disassembly of ACPI tables that +contain invocations of external control methods. The -fe<file> option +allows the import of a file that specifies the external methods along +with the required number of arguments for each -- allowing for the +correct disassembly of the table. This is a workaround for a limitation +of AML code where the disassembler often cannot determine the number of +arguments required for an external control method and generates incorrect +ASL code. See the iASL reference for details. ACPICA BZ 1030. + +Debugger: Implemented a new command (paths) that displays the full +pathnames (namepaths) and object types of all objects in the namespace. +This is an alternative to the namespace command. + +Debugger: Implemented a new command (sci) that invokes the SCI dispatch +mechanism and any installed handlers. + +iASL: Fixed a possible segfault for "too many parent prefixes" condition. +This can occur if there are too many parent prefixes in a namepath (for +example, ^^^^^^PCI0.ECRD). ACPICA BZ 1035. + +Application OSLs: Set the return value for the PCI read functions. These +functions simply return AE_OK, but should set the return value to zero +also. This change implements this. ACPICA BZ 1038. + +Debugger: Prevent possible command line buffer overflow. Increase the +size of a couple of the debugger line buffers, and ensure that overflow +cannot happen. ACPICA BZ 1037. + +iASL: Changed to abort immediately on serious errors during the parsing +phase. Due to the nature of ASL, there is no point in attempting to +compile these types of errors, and they typically end up causing a +cascade of hundreds of errors which obscure the original problem. + +---------------------------------------- 25 July 2013.
