Summary of changes for version 20191213: + + +1) ACPICA kernel-resident subsystem: + +Return a Buffer object for all fields created via the CreateField operator. Previously, an Integer would be returned if the size of the field was less than or equal to the current size of an Integer. Although this goes against the ACPI specification, it provides compatibility with other ACPI implementations. Also updated the ASLTS test suite to reflect this new behavior. + +2) iASL Compiler/Disassembler and ACPICA tools: + +iASL: Implemented detection of (and throw an error for) duplicate values for Case statements within a single Switch statement. Duplicate Integers, Strings, and Buffers are supported. + +iASL: Fix error logging issue during multiple file compilation -- Switch to the correct input file during error node creation. + +iASL: For duplicate named object creation, now emit an error instead of a warning - since this will cause a runtime error. + +AcpiSrc: Add unix line-ending support for non-Windows builds. + +iASL: Add an error condition for an attempt to create a NameString with > 255 NameSegs (the max allowable via the AML definition). + + +---------------------------------------- +18 October 2019. Summary of changes for version 20191018: + + +1) ACPICA kernel-resident subsystem: + +Debugger: added a new command: ?Fields [address space ID]?. This command +dumps the contents of all field units that are defined within the +namespace with a particular address space ID. + +Modified the external interface AcpiLoadTable() to return a table index. +This table index can be used for unloading a table for debugging. + ACPI_STATUS + AcpiLoadTable ( + ACPI_TABLE_HEADER *Table, + UINT32 *TableIndex)) + +Implemented a new external interface: AcpiUnloadTable() This new function +takes a table index as an argument and unloads the table. Useful for +debugging only. + ACPI_STATUS + AcpiUnloadTable ( + UINT32 TableIndex)) + +Ported the AcpiNames utility to use the new table initialization +sequence. The utility was broken before this change. Also, it was +required to include most of the AML interpreter into the utility in order +to process table initialization (module-level code execution.) + +Update for results from running Clang V8.0.1. This fixes all "dead +assignment" warnings. There are still several "Dereference of NULL +pointer" warnings, but these have been found to be false positive +warnings. + + +2) iASL Compiler/Disassembler and ACPICA tools: + +iASL: numerous table compiler changes to ensure that the usage of +yacc/bison syntax is POSIX-compliant. + +iASL/disassembler: several simple bug fixes in the data table +disassembler. + +Acpiexec: expanded the initialization file (the -fi option) to initialize +strings, buffers, packages, and field units. + + +---------------------------------------- +16 August 2019. Summary of changes for version 20190816: + +This release is available at https://acpica.org/downloads + + +1) ACPICA kernel-resident subsystem: + +Modified the OwnerId mechanism to allow for more Owner Ids. The previous +limit was 256 Ids, now it is 4096 Ids. This prevents OWNER_ID_LIMIT +exceptions on machines with a large number of initialization threads, +many CPU cores and nested initialization control methods. + +Introduced acpi_dispatch_gpe() as a wrapper around AcpiEvDetectGpe() for +checking if the given GPE (as represented by a GPE device handle and a +GPE number) is currently active and dispatching it (if that's the case) +outside of interrupt context. + +Table load: exit the interpreter before initializing objects within the +new table This prevents re-acquiring the interpreter lock when loading +tables + +Added the "Windows 2019" string to the _OSI support (version 1903). Jung- +uk Kim + +Macros: removed pointer math on a null pointer. Causes warnings on some +compilers and/or tools. Changed ACPI_TO_POINTER to use ACPI_CAST_PTR +instead of using arithmetic. + +Fully deployed the ACPI_PRINTF_LIKE macro. This macro was not being used +across all "printf-like" internal functions. Also, cleanup all calls to +such functions (both in 32-bit mode and 64-bit mode) now that they are +analyzed by the gcc compiler via ACPI_PRINTF_LIKE. + + +2) iASL Compiler/Disassembler and ACPICA tools: + +iASL: implemented a new data table compiler flex/bison front-end. This +change is internal and is not intended to result in changes to the +compiled code. This new compiler front-end can be invoked using the -tp +option for now, until the old mechanism is removed. + +ASLTS: Implemented a new data table compiler test suite. This test suite +generates all table templates and compile/disassemble/re-compile/binary- +compare each file. + +iASL: return -1 if AML files were not generated due to compiler errors + +iASL: added a warning on use of the now-legacy ASL Processor () keyword. + +iASL: added an error on _UID object declaration that returns a String +within a Processor () declaration. A _UID for a processor must be an +Integer. + +iASL: added a null terminator to name strings that consist only of +multiple parent prefixes (^) + +iASL: added support to compile both ASL and data table files in a single +command. + +Updated the tool generation project files that were recently migrated to +MSVC 2017 to eliminate all new warnings. The new project files appear in +the directory \acpica\generate\msvc2017. This change effectively +deprecates the older project files in \acpica\generate\msvc9. + + +---------------------------------------- 03 July 2019.
