This release is available at https://acpica.org/downloads
An Operation Region regression was fixed by properly adding address ranges to a global list during initialization. This allows OS to accurately check for overlapping regions between native devices (such as PCI) and Operation regions as well as checking for region conflicts between two Operation Regions.
Added support for the 2-byte extended opcodes in the code/feature that attempts to continue parsing during the table load phase. Skip parsing Device declarations (and other extended opcodes) when an error occurs during parsing. Previously, only single-byte opcodes were supported.
Cleanup: Simplified the module-level code support by eliminating a useless global variable (AcpiGbl_GroupModuleLeveCode).
2) iASL Compiler/Disassembler and Tools:
iASL/Preprocessor: Fixed a regression where an incorrect use of ACPI_FREE could cause a fault in the preprocessor. This was an inadvertent side-effect from moving more allocations/frees to the local cache/memory mechanism.
iASL: Enhanced error detection by validating that all NameSeg elements within a NamePatch actually exist. The previous behavior was spotty at best, and such errors could be improperly ignored at compiler time (never at runtime, however. There are two new error messages, as shown in the examples below:
dsdt.asl 33: CreateByteField (TTTT.BXXX, 1, CBF1)
Error 6161 - ^ One or more objects within the Pathname do not exist (TTTT.BXXX)
dsdt.asl 34: CreateByteField (BUF1, UUUU.INT1, BBBB.CBF1)
Error 6160 - One or more prefix Scopes do not exist ^ (BBBB.CBF1)
iASL: Disassembler/table-compiler: Added support for the static data table TPM2 revision 3 (an older version of TPM2). The support has been added for the compiler and the disassembler.
Fixed compilation of DOS format data table file on Unix/Linux systems. iASL now properly detects line continuations (\) for DOS format data table definition language files on when executing on Unix/Linux.
