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. Summary of changes for version 20190703: |
