---------------------------------------- 19 January 2017. Summary of changes for version 20170119: This release is available at https://acpica.org/downloads 1) General ACPICA software: Entire source code base: Added the 2017 copyright to all source code legal/licensing module headers and utility/tool signons. This includes the standard Linux dual-license header. This affects virtually every file in the ACPICA core subsystem, iASL compiler, all ACPICA utilities, and the ACPICA test suite. 2) iASL Compiler/Disassembler and Tools: iASL: Removed/fixed an inadvertent remark when a method argument containing a reference is used as a target operand within the method (and never used as a simple argument), as in the example below. Jeffrey Hugo. dsdt.asl 1507: Store(0x1, Arg0) Remark 2146 - ^ Method Argument is never used (Arg0) All tools: Removed the bit width of the compiler that generated the tool from the common signon for all user space tools. This proved to be confusing and unnecessary. This includes similar removal of HARDWARE_NAME from the generic makefiles (Thomas Petazzoni). Example below. Old: ASL+ Optimizing Compiler version 20170119-32 ASL+ Optimizing Compiler version 20170119-64 New: ASL+ Optimizing Compiler version 20170119 ---------------------------------------- 22 December 2016. 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. Summary of changes for version 20161117: 1) ACPICA kernel-resident subsystem: Table Manager: Fixed a regression introduced in 20160729, "FADT support cleanup". This was an attempt to remove all references in the source to the FADT version 2, which never was a legal version number. It was skipped because it was an early version of 64-bit support that was eventually abandoned for the current 64-bit support. Interpreter: Fixed a problem where runtime implicit conversion was incorrectly disabled for the ASL operators below. This brings the behavior into compliance with the ACPI specification: FromBCD ToBCD ToDecimalString ToHexString ToInteger ToBuffer Table Manager: Added a new public interface, AcpiPutTable, used to release and free an ACPI table returned by AcpiGetTable and related interfaces. Lv Zheng. 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: 140.5K Code, 58.5K Data, 198.9K Total Debug Version: 201.3K Code, 82.7K Data, 284.0K Total Previous Release: Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total Debug Version: 200.7K Code, 82.1K Data, 282.8K Total 2) iASL Compiler/Disassembler and Tools: Disassembler: Fixed a regression for disassembly of Resource Template. Detection of templates in the AML stream missed some types of templates. iASL: Fixed a problem where an Access Size error was returned for the PCC address space when the AccessSize of the GAS register is greater than a DWORD. Hoan Tran. iASL: Implemented several grammar changes for the operators below. These changes are slated for the next version of the ACPI specification: RefOf - Disallow method invocation as an operand CondRefOf - Disallow method invocation as an operand DerefOf - Disallow operands that use the result from operators that do not return a reference (Changed TermArg to SuperName). iASL: Control method invocations are now allowed for Target operands, as per the ACPI specification. Removed error for using a control method invocation as a Target operand. Disassembler: Improved detection of Resource Templates, Unicode, and Strings within Buffer objects. These subtypes do not contain a specific opcode to indicate the originating ASL code, and they must be detected by other means within the disassembler. iASL: Implemented an optimization improvement for 32-bit ACPI tables (DSDT/SSDT). For the 32-bit case only, compute the optimum integer opcode only after 64-bit to 32-bit truncation. A truncation warning message is still emitted, however. AcpiXtract: Implemented handling for both types of line terminators (LF or CR/LF) so that it can accept AcpiDump output files from any system. Peter Wu. AcpiBin: Added two new options for comparing AML files: -a: compare and display ALL mismatches -o: start compare at this offset into the second file
