---------------------------------------- 26 March 2020. Summary of changes for version 20200326: 1) ACPICA kernel-resident subsystem: Performed a code clean-up to prevent build errors on early versions of GCC-10. Added the NHLT table signature. iASL data table compiler/disassembler support for this table is coming soon. 2) iASL Compiler/Disassembler and ACPICA tools: AcpiExec: Fixed several problems with the namespace initialization file (-fi<filename> option). Includes fixes to prevent AE_ALREADY_EXISTS errors, several seg faults, and enhancements to line parsing within the init file. In addition, each object found in the init file and it's new value is displayed, as well as any such entries that do not have a corresponding name in the namespace. For reference, the syntax for the various supported data types are presented below: PCHG 0x777788889999BBBB // Integer \DEV1.STR1 "XYZ" // String BUF1 (88 99 AA) // Buffer PKG1 [0x1111 0x2222] // Package \BF1 0x7980 // BufferField RCRV 0x0123456789ABCDEF // Field Unit iASL: Added a custom iASL macro __EXPECT__(iASL-Error-Code). This macro can be used anywhere in a given ASL file to configure iASL to expect an iASL compiler error code on the line where this macro was placed. If the error code does not exist, an error is generated. This is intended to be used for ACPICA's ASL test suite, but can be used by ASL developers as well. iASL: table compiler: Implemented IVRS IVHD type 11h parsing. The AMD IVRS table parsing supported only IVHD type 10h structures. Parsing an IVHD type 11h caused the iasl to report unknown subtable type. Add necessary structure definition for IVHD type 11h and apply correct parsing method based on subtable type. Micha? ?ygowski. iASL: table compiler: Fixed IVRS table IVHD type 10h reserved field name According to AMD IOMMU Specification Revision 3.05 the reserved field should be IOMMU Feature Reporting. Change the name of the field to the correct one. Micha? ?ygowski. acpiexec: removed redeclaration of AcpiGbl_DbOpt_NoRegionSupport. Patch based on suggestions by David Seifert and Benjamin Berg. iASL: table compiler: removed an unused variable (DtCompilerParserResult) causing linking errors. Patch based on suggestions by David Seifert and Benjamin Berg. iASL: table compiler: make LexBuffer static to avoid linking errors in newer compilers. Patch based on suggestions by David Seifert and Benjamin Berg. iASL: fixed type matching between External and Named objects. External object types can only be expressed with ACPI object type values that are defined in the ACPI spec. However, iASL uses ACPI object type values that are local to ACPICA in addition to the values defined in the ACPI spec. This change implements type matching to map some object type values specific to ACPICA to ones that are defined in the ACPI spec. iASL: Dropped the type mismatch compiler error that can arise from External declarations to a warning. This warning can occur when there is a type difference between the external declaration and the actual object declaration (when compiling multiple files/modules simultaneously). iASL: removed an incorrect error message regarding externals. This change removes an incorrect error that is emitted when a duplicate external declaration does not contain a type that opens a scope. This is incorrect because the duplicate external with conflicting types are already caught by iASL and it doesn't make any sense to enforce what this conflicting type should be. AcpiXtract: fix AX_IS_TABLE_BLOCK_HEADER macro. This macro needs to be surrounded by parens. Otherwise, a logical statement that applies a logical not operator to this macro could result in a computation that applies the operator to the left side of the logical and but not the right. Reported-by: John Levon <john.levon@joyent.com> Fixed a problem with the local version of sprint(): On 32-bit, the provided sprintf() is non-functional: with a size of ACPI_UINT32_MAX, String + Size will wrap, meaning End < Start, and AcpiUtBoundStringOutput() will never output anything as a result. The symptom seen of this was acpixtract failing to output anything -- with a custom build that included utprint.c. Signed-off-by: John Levon <john.levon@joyent.com> iASL: Changed the "PlatformCommChannel" ASL keyword to "PCC", as per the ACPI specification. ---------------------------------------- 14 February 2020. Summary of changes for version 20200214: 1) ACPICA kernel-resident subsystem: Enable sleep button on ACPI legacy wake: Hibernation (S4) is triggered in a guest when it receives a sleep trigger from the hypervisor. When the guest resumes from this power state, it does not see the SleepEnabled bit. In other words, the sleepHibernation (S4) is triggered in a guest when it receives a sleep trigger from the hypervisor. When the guest resumes from this power state, it does not see the SleepEnabled bit. In other words, the sleep button is not enabled on waking from an S4 state. This causes subsequent invocation of sleep state to fail since the guest.button is not enabled on waking from an S4 state. This causes subsequent invocation of sleep state to fail in the guest. Fix this problem by enabling the sleep button in ACPI legacy wake. From Anchal Agarwal <anchalag@amazon.com>. Implemented a new external interface, AcpiAnyGpeStatusSet (). To be used for checking the status bits of all enabled GPEs in one go. It is needed to distinguish spurious SCIs from genuine ones when deciding whether or not to wake up the system from suspend-to-idle. Generic Makefiles: replace HOST name with ACPI_HOST: Some machines may be using HOST in their environment to represent the host name for their machines. Avoid this problem by renaming this variable from HOST to ACPI_HOST. MSVC 2017 project files: Enable multiprocessor generation to improve build performance. Added a macro to get the byte width of a Generic Address structure. New ACPI_ACCESS_BYTE_WIDTH is in addition to the existing ACPI_ACCESS_BIT_WIDTH. From Mika Westerberg. 2) iASL Compiler/Disassembler and ACPICA tools: iASL: Implemented full support for the (optional, rarely used) ReturnType and ParameterTypesList for the Method, Function, and External operators. For Method declarations, the number of individual ParameterTypes must match the declaration of the number of arguments (NumArgs). This also Fixes a problem with the External operator where extra/extraneous bytes were emitted in the AML code if the optional ReturnType/ParameterTypes were specified for a MethodObj declaration. New error message: 1) Method NumArgs count does not match length of ParameterTypes list iASL: Implemented detection of type mismatches between External declarations and named object declarations. Also, detect type mismatches between multiple External declarations of the same Name. New error messages: 1) Type mismatch between external declaration and actual object declaration detected 2) Type mismatch between multiple external declarations detected iASL: Implemented new error messages for External operators that specify a ReturnType and/or ParameterTypesList for any object type other than control methods (MethodObj). New error messages: 1) Return type is only allowed for Externals declared as MethodObj 2) Parameter type is only allowed for Externals declared as MethodObj iASL: Implemented two new remark/warning messages for ASL code that creates named objects from within a control method. This is very inefficient since the named object must be created and deleted each time the method is executed. New messages: 1) Creation of named objects within a method is highly inefficient, use globals or method local variables instead (remark) 2) Static OperationRegion should be declared outside control method (warning) iASL: Improved illegal forward reference detection by adding support to detect forward-reference method invocations. iASL: Detect and issue an error message for NameStrings that contain too many individual NameSegs (>255). This is an AML limitation that is defined in the ACPI specification. New message: 1) NameString contains too many NameSegs (>255) acpidump: windows: use GetSystemFirmwareTable API for all tables except SSDT. By using this API, acpidump is able to get all tables in the XSDT iASL: Removed unused parser file and updated msvc2017 project files. Removed the obsolete AslCompiler.y from the repository. iASL: msvc2017: Fixed macros in the file dependency list to prevent unnecessary rebuilds. Replace %(Directory) with %(RelativeDir). Disassembler: Prevent spilling error messages to the output file. All errors are directed to the console instead. These error messages prevented re-compilation of the resulting disassembled ASL output file (.DSL). ---------------------------------------- 10 January 2020. Summary of changes for version 20200110: 1) ACPICA kernel-resident subsystem: Updated all copyrights to 2020. This affects all ACPICA source code modules. 2) iASL Compiler/Disassembler and ACPICA tools: ASL test suite (ASLTS): Updated all copyrights to 2020. Tools and utilities: Updated all signon copyrights to 2020. iASL: fix forward reference analysis for field declarations. Fixes forward reference analysis for field declarations by searching the parent scope for the named object when the object is not present in the current scope. iASL: Improved the error output for ALREADY_EXISTS errors. Now, the full pathname of the name that already exists is printed. iASL: Enhance duplicate Case() detection for buffers. Add check for buffers with no initializer list (these buffers will be filled with zeros at runtime.)
