Summary of changes for version 20221020: + +This release is available at https://acpica.org/downloads + +0) Global changes: + +Allow disabling of -Werror. For distro maintainers having `-Werror` can +delay update of GCC. Since every GCC release might add new warnings that +were not yet captured, it might break the build of packages. With this +change, distros can now build with `NOWERROR=TRUE` instead of patching +either the errors or the makefiles. The default behavior keeps on using +`-Werror`. + +1) ACPICA kernel-resident subsystem: + +Added support for FFH Operation Region special context data. FFH(Fixed +Function Hardware) Opregion is approved to be added in ACPI 6.5 via code +first approach[1]. It requires special context data similar to GPIO and +Generic Serial Bus as it needs to know platform specific offset and +length. + +Reverted this commit "executer/exsystem: Warn about sleeps greater than +10 ms." Due to user complaints about valid sleeps greater than 10ms seen +in some existing machines -- generating lots of warnings. + +Do not touch VGA memory when EBDA < 1KiB. The ACPICA code assumes that +EBDA region must be at least 1KiB in size. Because this is not +guaranteed, it might happen that while scanning the memory for RSDP +pointer, the kernel touches memory above 640KiB. This is unwanted as the +VGA memory range may not be decoded or even present when running under +virtualization. + +Check that EBDA pointer is in valid memory. If the memory at 0x40e is +uninitialized, the retrieved physical memory address of EBDA may be +beyond the low memory (i.e. above 640K). If so, the kernel may +unintentionally access the VGA memory, that might not be decoded or even +present in case of virtualization. + +2) iASL Compiler/Disassembler and ACPICA tools: + +Completed the existing partial support for the CDAT "table". Although +this isn't technically an ACPI table (It doesn't go into the XSDT), it is +possible to support this table in the Data Table compiler. Created one +new file, "utilities/utcksum.c", used to centralize checksum +generation/validation into one location. Includes changes to makefiles +and MSVC project files. + +Updated support for the IORT table - update to version E.e + +Added CXL 3.0 structures (CXIMS & RDPAS) to the CEDT table + +iASL: Added CCEL table to both compiler/disassembler. + +iASL: NHLT table: Fixed compilation of optional undocumented fields + +iASL: Fix iASL compile error due to ACPI_TDEL_OFFSET. Commit # 10e4763 +("iASL: Add CCEL table to both compiler/disassembler") introduced the +iASL build issue. The issue is due to using ACPI_TDEL_OFFSET for CCEL +table member reference. To fix it, change ACPI_TDEL_OFFSET with +ACPI_CCEL_OFFSET. + ---------------------------------------- 31 March 2022. Summary of changes for version 20220331: -- cgit v1.2.1
