Summary of changes for version 20161222: + + +1) ACPICA kernel-resident subsystem: + +AML Debugger: Implemented a new mechanism to simplify and enhance +debugger integration into all environments, including kernel debuggers +and user-space utilities, as well as remote debug services. This +mechanism essentially consists of new OSL interfaces to support debugger +initialization/termination, as well as wait/notify interfaces to perform +the debugger handshake with the host. Lv Zheng. + + New OSL interfaces: + AcpiOsInitializeDebugger (void) + AcpiOsTerminateDebugger (void) + AcpiOsWaitCommandReady (void) + AcpiOsNotifyCommandComplete (void) + + New OS services layer: + osgendbg.c -- Example implementation, and used for AcpiExec + +Update for Generic Address Space (GAS) support: Although the AccessWidth +and/or BitOffset fields of the GAS are not often used, this change now +fully supports these fields. This affects the internal support for FADT +registers, registers in other ACPI data tables, and the AcpiRead and +AcpiWrite public interfaces. Lv Zheng. + +Sleep support: In order to simplify integration of ACPI sleep for the +various host operating systems, a new OSL interface has been introduced. +AcpiOsEnterSleep allows the host to perform any required operations +before the final write to the sleep control register(s) is performed by +ACPICA. Lv Zheng. + + New OSL interface: + AcpiOsEnterSleep(SleepState, RegisterAValue, RegisterBValue) + + Called from these internal interfaces: + AcpiHwLegacySleep + AcpiHwExtendedSleep + +EFI support: Added a very small EFI/ACPICA example application. Provides +a simple demo for EFI integration, as well as assisting with resolution +of issues related to customer ACPICA/EFI integration. Lv Zheng. See: + + source/tools/efihello/efihello.c + +Local C library: Implemented several new functions to enhance ACPICA +portability, for environments where these clib functions are not +available (such as EFI). Lv Zheng: + putchar + getchar + strpbrk + strtok + memmove + +Fixed a regression where occasionally a valid resource descriptor was +incorrectly detected as invalid at runtime, and a +AE_AML_NO_RESOURCE_END_TAG was returned. + +Fixed a problem with the recently implemented support that enables +control method invocations as Target operands to many ASL operators. +Warnings of this form: "Needed type [Reference], found [Processor]" were +seen at runtime for some method invocations. + +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: 141.5K Code, 58.5K Data, 200.0K Total + Debug Version: 201.7K Code, 82.7K Data, 284.4K Total + Previous Release: + Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total + Debug Version: 201.3K Code, 82.7K Data, 284.0K Total + + +2) iASL Compiler/Disassembler and Tools: + +Disassembler: Enhanced output by adding the capability to detect and +disassemble ASL Switch/Case statements back to the original ASL source +code instead of if/else blocks. David Box. + +AcpiHelp: Split a large file into separate files based upon +functionality/purpose. New files are: + ahaml.c + ahasl.c + +---------------------------------------- 17 November 2016.
