Import acpica-20230628 (last was 20221020) ---------------------------------------- 28 June 2023. Summary of changes for version 20230628: 0) Global changes: Fixed a problem with the ASL/AML Timer() operator. Discovered by UBSAN: ?array-index-out-of-bounds in acpica/dswexec.c:401:12 index -1 is out of range for type 'acpi_operand_object?. Added AML_NO_OPERAND_RESOLVE flag to Timer (since there are no runtime arguments). Reported by: Abhishek Mainkar abmainkar@nvidia.com. Added a define for size of acpi_srat_generic_affinity DeviceHandle. Replaced a magic number with a define. The Linux kernel code will utilize this. Reported by Dave Jiang dave.jiang@intel.com. Added support for _DSC (Deepest State for Configuration) as per ACPI 6.5. 1) ACPICA kernel-resident subsystem: Added port definitions for CDAT SSLBIS. Add upstream port and any port definitions for SSLBIS. Reported by: Dave Jiang dave.jiang@intel.com. Fixed misspelled CDAT DSMAS define: ACPI_CEDT_DSMAS_NON_VOLATILE -> ACPI_CDAT_DSMAS_NON_VOLATILE. Reported by: Dave Jiang dave.jiang@intel.com. 1) ACPICA kernel-resident subsystem: Fix GCC 12 dangling-pointer warning. We're storing a persistent pointer to an ephemeral local variable which technically is a dangling pointer and the compiler is correct. However, since we never indirect the pointer, this is a safe operation and we can suppress the warning. Also, some C run-times (like MUSL) aren't including <stdint.h> indirectly so we must include it explicitly or we won't have the type definition for uintptr_t. 2) iASL Compiler/Disassembler and ACPICA tools:. IASL/RHCT: Enable dumping and compiling newly added nodes. The RHCT table is updated with new nodes. Add compile and dump functionality for these new structures. AcpiExec: Added a new command, ?interrupt?. The Interrupt command simulates an interrupt with a IntID (GSIV) equal to the first argument of the call/invocation. The acpiexec code simulates the behavior by OSPM: execute the _EVT method of the GED device associated with that IntID. Submitted by: Jose Marinho jose.marinho@arm.com. AcpiExec: Detect GED device and keep track of _EVT. The GED device is described by a _HID of ACPI0013. This code traverses the namespace identifying all GED devices. For each GED device in the namespace we record the Interrupt object and the _EVT method. This information is used when an interrupt is simulated via the ?interrupt? command. Submitted by: Jose Marinho jose.marinho@arm.com. ---------------------------------------- 31 March 2023. Summary of changes for version 20230331: This release is available at https://acpica.org/downloads 0) Global changes: Update all copyright notices to the year 2023. This effects all source modules, as well as utility signons. Add OS-specific support for Zephyr RTOS. Fix miscellaneous code that accesses various objects. Remove some dead code. Add C ?Flexible Array? support. Add support for 64 bit LoongArch compilation. Add first batch of RISC-V related definitions. Performed a global automated update to remove tabs, fix indentation issues, etc. 1) ACPICA kernel-resident subsystem: hwvalid: Drop port I/O validation. 2) ACPICA tools and utilities: iASL: Added full macro support in the preprocessor. Example: #define ABCD(a,b,c,d) a+b+c-d Known macro support limitations (at this time): No support for multi-line #define macros (backslash continuation lines) No support for the C-style ternary operator No support for the stringizing operator (#) No support for the concatenation (token pasting) operator (##) No support for variable number of macro arguments Add support for AMD Secure Processor Table (ASPT) version 1. Add support for Arm's MPAM ACPI table version 2. ACPI 6.5: MADT: add support for trace buffer extension in GICC. Headers: Delete bogus NodeArray array of pointers from AEST table. PHAT table support is still ongoing.

----------------------------------------
31 March 2022. Summary of changes for version 20220331:
0) Global changes:
Update all copyright notices to the year 2022. This effects all source
modules, as well as utility signons.
1) ACPICA kernel-resident subsystem:
For the ASL Sleep() operator, issue a warning if the sleep value is
greater than 10 Milliseconds. Quick boottime is important, so warn about
sleeps greater than 10 ms. Distribution Linux kernels reach initrd in 350
ms, so excessive delays should be called out. 10 ms is chosen randomly,
but three of such delays would already make up ten percent of the
boottime.
Namespace: Avoid attempting to walk the Namespace if the Namespace does
not exist.
AML interpreter/iASL compiler: Add new Acpi 6.4 semantics for the
LoadTable and Load operators. DDB_HANDLE is gone, now loadtable returns a
pass/fail integer. Now load returns a pass/fail integer, as well as
storing the return value in an optional 2nd argument.
Headers: Use uintptr_t and offsetof() in Linux kernel builds. To avoid
"performing pointer subtraction with a null pointer has undefined
behavior" compiler warnings, use uintptr_t and offsetof() that are always
available during Linux kernel builds to define ACPI_UINTPTR_T and the
ACPI_TO_INTEGER() and ACPI_OFFSET() macros when building the ACPICA code
in the Linux kernel.
Added support for the Windows 11 _OSI string ("Windows 2021"). Submitted
by superm1.
executer/exsystem: Inform users about ACPI spec violation for the Stall()
operator. Values greater than 100 microseconds violate the ACPI
specification, so warn users about it. From the ACPI Specification
version 6.2 Errata A, 19.6.128 *Stall (Stall for a Short Time)*:
> The implementation of Stall is OS-specific, but must not relinquish
> control of the processor. Because of this, delays longer than 100
> microseconds must use Sleep instead of Stall.
2) iASL Compiler/Disassembler and ACPICA tools:
Data Table Compiler/Disassembler: Add support for the APMT table - ARM
Performance Monitoring Unit table. Submitted by @bwicaksononv.
Data Table Compiler/Disassembler: For MADT, add support for the OEM-
defined subtables (Types 0x80-0x7F).
Data Table Compiler: Fixed a problem with support for the SDEV table,
where a subtable Length was not computed correctly.
Data Table Compiler/Disassembler: Add/fix the CFMWS subtable to the CEDT
Acpi table support.
Data Table Compiler/Disassembler: Fix a compile issue with the CEDT and
add template. Submitted by MasterDrogo.
Data Table Compiler/Disassembler: NHLT Changes provided by Piotr Maziarz:
iASL/NHLT: Rename linux specific structures to DeviceInfo to improve
readability of the code.
iASL/NHLT: Fix parsing undocumented bytes at the end of Endpoint.
Undocumented bytes at the end of Endpoint Descriptor can be present
independently of Linux-specific structures. Their size can also vary.
iASL/NHLT: Treat TableTerminator as SpecificConfig. SpecificConfig has 4
bytes of size and then an amount of bytes specified by size. All of the
terminators that I've seen had a size equal to 4, but theoretically it
can vary.
iASL/AcpiExec: Use _exit instead of exit in signal handers (ctrl-C).
iASL: Remove a remark due to excessive output. Removed a remark for
duplicate Offset() operators, due to a user complaint.

31 March 2021. Summary of changes for version 20210331: This release is available at https://acpica.org/downloads, and includes all ACPI 6.4 support 1) ACPICA kernel-resident subsystem: ACPI 6.4: iASL: deprecate DDBHandleObj keyword Always create namespace nodes using AcpiNsCreateNode(). ACPICA is allocating an object using kmalloc(), but then frees it using kmem_cache_free(<"Acpi-Namespace" kmem_cache>). This is wrong. Fixed a race condition in generic serial bus operation region handler. Fixed by Hans de Goede. 2) iASL Compiler/Disassembler and ACPICA tools: ACPI 6.4: NFIT: add Location Cookie field ACPI 6.4: HMAT: add new fields/flags ACPI 6.4: Add new flags in SRAT ACPI 6.4: add SDEV secure access components ACPI 6.4: add Csi2Bus resource template ACPI 6.4: add support for PHAT table ACPI 6.4: add support for PMTT table Add disassembly support for the IVRS table. Compilation of the table is not yet complete. Fixed a potential infinite loop due to type mismatch. The for-loop is using a UINT8 counter and comparing the upper limit against a UINT32 AslGbl_ExpectedMessagesIndex maximum. In the case where AslGbl_ExpectedMessagesIndex is > 255 the counter i will wrap around to zero and the loop will never exit. I suspect the AslGbl_ExpectedMessagesIndex is never that high, but fixing this does future proof the code and cleans up static analysis warnings.Colin King. iASL/TableCompiler: update it with IORT table E.b revision changes. From shamiali2008. iASL/TableCompiler: Add compilation support for the VIOT table. Signed-off-by: Jean-Philippe Brucker. iASL/TableCompiler: Add compilation support for CEDT table. Also, update the CEDT template.

---------------------------------------- 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.)

----------------------------------------
05 April 2019. Summary of changes for version 20190405:
1) ACPICA kernel-resident subsystem:
Event Manager: History: Commit 18996f2db918 ("ACPICA: Events: Stop
unconditionally clearing ACPI IRQs during suspend/resume") was added
earlier to stop clearing of event status bits unconditionally on suspend
and resume paths. Though this change fixed an issue on suspend path, it
introduced regressions on several resume paths. In the case of S0ix,
events are enabled as part of device suspend path. If status bits for the
events are set when they are enabled, it could result in premature wake
from S0ix. If status is cleared for any event that is being enabled so
that any stale events are cleared out. In case of S0ix, events are
enabled as part of device suspend path. If status bits for the events are
set when they are enabled, it could result in premature wake from S0ix.
This change ensures that status is cleared for any event that is being
enabled so that any stale events are cleared out.
2) iASL Compiler/Disassembler and ACPICA tools:
iASL: Implemented an enhanced multiple file compilation that combines
named objects from all input files to a single namespace. With this
feature, any unresolved external declarations as well as duplicate named
object declarations can be detected during compilation rather than
generating errors much later at runtime. The following commands are
examples that utilize this feature:
iasl dsdt.asl ssdt.asl
iasl dsdt.asl ssdt1.asl ssdt2.asl
iasl dsdt.asl ssdt*.asl
----------------------------------------
29 March 2019. Summary of changes for version 20190329:
1) ACPICA kernel-resident subsystem:
Namespace support: Remove the address nodes from global list after method
termination. The global address list contains pointers to namespace nodes
that represent Operation Regions. This change properly removes Operation
Region namespace nodes that are declared dynamically during method
execution.
Linux: Use a different debug default than ACPICA. There was a divergence
between Linux and the ACPICA codebases. In order to resolve this
divergence, Linux now declares its own debug default in aclinux.h
Renamed some internal macros to improve code understanding and
maintenance. The macros below all operate on single 4-character ACPI
NameSegs, not generic strings (old -> new):
ACPI_NAME_SIZE -> ACPI_NAMESEG_SIZE
ACPI_COMPARE_NAME -> ACPI_COMPARE_NAMESEG
ACPI_MOVE_NAME -> ACPI_COPY_NAMESEG
Fix for missing comma in array declaration for the AcpiGbl_GenericNotify
table.
Test suite: Update makefiles, add PCC operation region support
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented additional illegal forward reference detection. Now
detect and emit an error upon detection of a forward reference from a
Field to an Operation Region. This will fail at runtime if allowed to
pass the compiler.
AcpiExec: Add an address list check for dynamic Operation Regions. This
feature performs a sanity test for each node the global address list.
This is done in order to ensure that all dynamic operation regions are
properly removed from the global address list and no dangling pointers
are left behind.
Disassembler: Improved generation of resource pathnames. This change
improves the code that generates resource descriptor and resource tag
pathnames. The original code used a bunch of str* C library functions
that caused warnings on some compilers.
iASL: Removed some uses of strncpy and replaced with memmove. The strncpy
function can overwrite buffers if the calling code is not very careful.
In the case of generating a module/table header, use of memmove is a
better implementation.
3) Status of new features that have not been completed at this time:
iASL: Implementing an enhanced multiple file compilation into a single
namespace feature (Status): This feature will be released soon, and
allows multiple ASL files to be compiled into the same single namespace.
By doing so, any unresolved external declarations as well as duplicate
named object declarations can be detected during compilation (rather than
later during runtime). The following commands are examples that utilize
this feature:
iasl dsdt.asl ssdt.asl
iasl dsdt.asl ssdt1.asl ssdt2.asl
iasl dsdt.asl ssdt*.asl
ASL tutorial status: Feedback is being gathered internally and the
current plan is to publish this tutorial on the ACPICA website after a
final review by a tech writer.
----------------------------------------
15 February 2019. Summary of changes for version 20190215:
0) Support for ACPI specification version 6.3:
Add PCC operation region support for the AML interpreter. This adds PCC
operation region support in the AML interpreter and a default handler for
acpiexec. The change also renames the PCC region address space keyword to
PlatformCommChannel.
Support for new predefined methods _NBS, _NCH, _NIC, _NIH, and _NIG.
These methods provide OSPM with health information and device boot
status.
PDTT: Add TriggerOrder to the PCC Identifier structure. The field value
defines if the trigger needs to be invoked by OSPM before or at the end
of kernel crash dump processing/handling operation.
SRAT: Add Generic Affinity Structure subtable. This subtable in the SRAT
is used for describing devices such as heterogeneous processors,
accelerators, GPUs, and IO devices with integrated compute or DMA
engines.
MADT: Add support for statistical profiling in GICC. Statistical
profiling extension (SPE) is an architecture-specific feature for ARM.
MADT: Add online capable flag. If this bit is set, system hardware
supports enabling this processor during OS runtime.
New Error Disconnect Recover Notification value. There are a number of
scenarios where system Firmware in collaboration with hardware may
disconnect one or more devices from the rest of the system for purposes
of error containment. Firmware can use this new notification value to
alert OSPM of such a removal.
PPTT: New additional fields in Processor Structure Flags. These flags
provide more information about processor topology.
NFIT/Disassembler: Change a field name from "Address Range" to "Region
Type".
HMAT updates: make several existing fields to be reserved as well as
rename subtable 0 to "memory proximity domain attributes".
GTDT: Add support for new GTDT Revision 3. This revision adds information
for the EL2 timer.
iASL: Update the HMAT example template for new fields.
iASL: Add support for the new revision of the GTDT (Rev 3).
1) ACPICA kernel-resident subsystem:
AML Parser: fix the main AML parse loop to correctly skip erroneous
extended opcodes. AML opcodes come in two lengths: 1-byte opcodes and 2-
byte extended opcodes. If an error occurs during an AML table load, the
AML parser will continue loading the table by skipping the offending
opcode. This implements a "load table at any cost" philosophy.
2) iASL Compiler/Disassembler and Tools:
iASL: Add checks for illegal object references, such as a reference
outside of method to an object within a method. Such an object is only
temporary.
iASL: Emit error for creation of a zero-length operation region. Such a
region is rather pointless. If encountered, a runtime error is also
implemented in the interpeter.
Debugger: Fix a possible fault with the "test objects" command.
iASL: Makefile: support parent directory filenames containing embedded
spaces.
iASL: Update the TPM2 template to revision 4.
iASL: Add the ability to report specific warnings or remarks as errors.
Disassembler: Disassemble OEMx tables as actual AML byte code.
Previously, these tables were treated as "unknown table".
iASL: Add definition and disassembly for TPM2 revision 3.
iASL: Add support for TPM2 rev 3 compilation.
----------------------------------------

----------------------------------------
13 March 2018. Summary of changes for version 20180313:
1) ACPICA kernel-resident subsystem:
Implemented various improvements to the GPE support:
1) Dispatch all active GPEs at initialization time so that no GPEs are
lost.
2) Enable runtime GPEs earlier. Some systems expect GPEs to be enabled
before devices are enumerated.
3) Don't unconditionally clear ACPI IRQs during suspend/resume, so that
IRQs are not lost.
4) Add parallel GPE handling to eliminate the possibility of dispatching
the same GPE twice.
5) Dispatch any pending GPEs after enabling for the first time.
AcpiGetObjectInfo - removed support for the _STA method. This was causing
problems on some platforms.
Added a new _OSI string, "Windows 2017.2".
Cleaned up and simplified the module-level code support. These changes
are in preparation for the eventual removal of the legacy MLC support
(deferred execution), replaced by the new MLC architecture which executes
the MLC as a table is loaded (DSDT/SSDTs).
Changed a compile-time option to a runtime option. Changes the option to
ignore ACPI table load-time package resolution errors into a runtime
option. Used only for platforms that generate many AE_NOT_FOUND errors
during boot. AcpiGbl_IgnorePackageResolutionErrors.
Fixed the ACPI_ERROR_NAMESPACE macro. This change involves putting some
ACPI_ERROR_NAMESPACE parameters inside macros. By doing so, we avoid
compilation errors from unused variables (seen with some compilers).
2) iASL Compiler/Disassembler and Tools:
ASLTS: parallelized execution in order to achieve an (approximately) 2X
performance increase.
ASLTS: Updated to use the iASL __LINE__ and __METHOD__ macros. Improves
error reporting.
----------------------------------------
09 February 2018. Summary of changes for version 20180209:
1) ACPICA kernel-resident subsystem:
Completed the final integration of the recent changes to Package Object
handling and the module-level AML code support. This allows forward
references from individual package elements when the package object is
declared from within module-level code blocks. Provides compatibility
with other ACPI implementations.
The new architecture for the AML module-level code has been completed and
is now the default for the ACPICA code. This new architecture executes
the module-level code in-line as the ACPI table is loaded/parsed instead
of the previous architecture which deferred this code until after the
table was fully loaded. This solves some ASL code ordering issues and
provides compatibility with other ACPI implementations. At this time,
there is an option to fallback to the earlier architecture, but this
support is deprecated and is planned to be completely removed later this
year.
Added a compile-time option to ignore AE_NOT_FOUND exceptions during
resolution of named reference elements within Package objects. Although
this is potentially a serious problem, it can generate a lot of
noise/errors on platforms whose firmware carries around a bunch of unused
Package objects. To disable these errors, define
ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header. All
errors are always reported for ACPICA applications such as AcpiExec.
Fixed a regression related to the explicit type-conversion AML operators
(ToXXXX). The regression was introduced early in 2017 but was not seen
until recently because these operators are not fully supported by other
ACPI implementations and are thus rarely used by firmware developers. The
operators are defined by the ACPI specification to not implement the
"implicit result object conversion". The regression incorrectly
introduced this object conversion for the following explicit conversion
operators:
ToInteger
ToString
ToBuffer
ToDecimalString
ToHexString
ToBCD
FromBCD
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a problem with the compiler constant folding feature as
related to the ToXXXX explicit conversion operators. These operators do
not support the "implicit result object conversion" by definition. Thus,
ASL expressions that use these operators cannot be folded to a simple
Store operator because Store implements the implicit conversion. This
change uses the CopyObject operator for the ToXXXX operator folding
instead. CopyObject is defined to not implement implicit result
conversions and is thus appropriate for folding the ToXXXX operators.
iASL: Changed the severity of an error condition to a simple warning for
the case where a symbol is declared both locally and as an external
symbol. This accommodates existing ASL code.
AcpiExec: The -ep option to enable the new architecture for module-level
code has been removed. It is replaced by the -dp option which instead has
the opposite effect: it disables the new architecture (the default) and
enables the legacy architecture. When the legacy code is removed in the
future, the -dp option will be removed also.
----------------------------------------
05 January 2018. Summary of changes for version 20180105:
1) ACPICA kernel-resident subsystem:
Updated all copyrights to 2018. This affects all source code modules.
Fixed a possible build error caused by an unresolved reference to the
AcpiUtSafeStrncpy function.
Removed NULL pointer arithmetic in the various pointer manipulation
macros. All "(void *) NULL" constructs are converted to "(void *) 0".
This eliminates warnings/errors in newer C compilers. Jung-uk Kim.
Added support for A32 ABI compilation, which uses the ILP32 model. Anuj
Mittal.
2) iASL Compiler/Disassembler and Tools:
ASLTS: Updated all copyrights to 2018.
Tools: Updated all signon copyrights to 2018.
AcpiXtract: Fixed a regression related to ACPI table signatures where the
signature was truncated to 3 characters (instead of 4).
AcpiExec: Restore the original terminal mode after the use of the -v and
-vd options.
ASLTS: Deployed the iASL __METHOD__ macro across the test suite.
----------------------------------------
14 December 2017. Summary of changes for version 20171214:
1) ACPICA kernel-resident subsystem:
Fixed a regression in the external (public) AcpiEvaluateObjectTyped
interface where the optional "pathname" argument had inadvertently become
a required argument returning an error if omitted (NULL pointer
argument).
Fixed two possible memory leaks related to the recently developed "late
resolution" of reference objects within ASL Package Object definitions.
Added two recently defined _OSI strings: "Windows 2016" and "Windows
2017". Mario Limonciello.
Implemented and deployed a safer version of the C library function
strncpy: AcpiUtSafeStrncpy. The intent is to at least prevent the
creation of unterminated strings as a possible result of a standard
strncpy.
Cleaned up and restructured the global variable file (acglobal.h). There
are many changes, but no functional changes.
2) iASL Compiler/Disassembler and Tools:
iASL Table Compiler: Fixed a problem with the DBG2 ACPI table where the
optional OemData field at the end of the table was incorrectly required
for proper compilation. It is now correctly an optional field.
ASLTS: The entire suite was converted from standard ASL to the ASL+
language, using the ASL-to-ASL+ converter which is integrated into the
iASL compiler. A binary compare of all output files has verified the
correctness of the conversion.
iASL: Fixed the source code build for platforms where "char" is unsigned.
This affected the iASL lexer only. Jung-uk Kim.

----------------------------------------
31 August 2017. Summary of changes for version 20170831:
1) ACPICA kernel-resident subsystem:
Implemented internal support for full 64-bit addresses that appear in all
Generic Address Structure (GAS) structures. Previously, only the lower 32
bits were used. Affects the use of GAS structures in the FADT and other
tables, as well as the GAS structures passed to the AcpiRead and
AcpiWrite public external interfaces that are used by drivers. Lv Zheng.
Added header support for the PDTT ACPI table (Processor Debug Trigger
Table). Full support in the iASL Data Table Compiler and disassembler is
forthcoming.
2) iASL Compiler/Disassembler and Tools:
iASL/Disassembler: Fixed a problem with the PPTT ACPI table (Processor
Properties Topology Table) where a flag bit was specified in the wrong
bit position ("Line Size Valid", bit 6).
iASL: Implemented support for Octal integer constants as defined by the
ASL language grammar, per the ACPI specification. Any integer constant
that starts with a zero is an octal constant. For example,
Store (037777, Local0) /* Octal constant */
Store (0x3FFF, Local0) /* Hex equivalent */
Store (16383, Local0) /* Decimal equivalent */
iASL: Improved overflow detection for 64-bit string conversions during
compilation of integer constants. "Overflow" in this case means a string
that represents an integer that is too large to fit into a 64-bit value.
Any 64-bit constants within a 32-bit DSDT or SSDT are still truncated to
the low-order 32 bits with a warning, as previously implemented. Several
new exceptions are defined that indicate a 64-bit overflow, as well as
the base (radix) that was used during the attempted conversion. Examples:
Local0 = 0xAAAABBBBCCCCDDDDEEEEFFFF // AE_HEX_OVERFLOW
Local0 = 01111222233334444555566667777 // AE_OCTAL_OVERFLOW
Local0 = 11112222333344445555666677778888 // AE_DECIMAL_OVERFLOW
iASL: Added a warning for the case where a ResourceTemplate is declared
with no ResourceDescriptor entries (coded as "ResourceTemplate(){}"). In
this case, the resulting template is created with a single END_TAG
descriptor, which is essentially useless.
iASL: Expanded the -vw option (ignore specific warnings/remarks) to
include compilation error codes as well.
----------------------------------------
28 July 2017. Summary of changes for version 20170728:
1) ACPICA kernel-resident subsystem:
Fixed a regression seen with small resource descriptors that could cause
an inadvertent AE_AML_NO_RESOURCE_END_TAG exception.
AML interpreter: Implemented a new feature that allows forward references
from individual named references within package objects that are
contained within blocks of "module-level code". This provides
compatibility with other ACPI implementations and supports existing
firmware that depends on this feature. Example:
Name (ABCD, 1)
If (ABCD) /* An If() at module-level */
{
Name (PKG1, Package()
{
INT1 /* Forward reference to object INT1
*/
})
Name (INT1, 0x1234)
}
AML Interpreter: Fixed a problem with the Alias() operator where aliases
to some ASL objects were not handled properly. Objects affected are:
Mutex, Event, and OperationRegion.
AML Debugger: Enhanced to properly handle AML Alias objects. These
objects have one level of indirection which was not fully supported by
the debugger.
Table Manager: Added support to detect and ignore duplicate SSDTs within
the XSDT/RSDT. This error in the XSDT has been seen in the field.
EFI and EDK2 support:
Enabled /WX flag for MSVC builds
Added support for AcpiOsStall, AcpiOsSleep, and AcpiOsGetTimer
Added local support for 64-bit multiply and shift operations
Added support to compile acpidump.efi on Windows
Added OSL function stubs for interfaces not used under EFI
Added additional support for the _DMA predefined name. _DMA returns a
buffer containing a resource template. This change add support within the
resource manager (AcpiWalkResourceBuffer) to walk and parse this list of
resource descriptors. Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a problem where the internal input line buffer(s) could
overflow if there are very long lines in the input ASL source code file.
Implemented buffer management that automatically increases the size of
the buffers as necessary.
iASL: Added an option (-vx) to "expect" particular remarks, warnings and
errors. If the specified exception is not raised during compilation, the
compiler emits an error. This is intended to support the ASL test suite,
but may be useful in other contexts.
iASL: Implemented a new predefined macro, __METHOD__, which returns a
string containing the name of the current control method that is being
compiled.
iASL: Implemented debugger and table compiler support for the SDEI ACPI
table (Software Delegated Exception Interface). James Morse
<james.morse@arm.com>
Unix/Linux makefiles: Added an option to disable compile optimizations.
The disable occurs when the NOOPT flag is set to TRUE.
theracermaster@gmail.com
Acpidump: Added support for multiple DSDT and FACS tables. This can occur
when there are different tables for 32-bit versus 64-bit.
Enhanced error reporting for the ASL test suite (ASLTS) by removing
unnecessary/verbose text, and emit the actual line number where an error
has occurred. These changes are intended to improve the usefulness of the
test suite.
----------------------------------------
29 June 2017. Summary of changes for version 20170629:
1) ACPICA kernel-resident subsystem:
Tables: Implemented a deferred ACPI table verification. This is useful
for operating systems where the tables cannot be verified in the early
initialization stage due to early memory mapping limitations on some
architectures. Lv Zheng.
Tables: Removed the signature validation for dynamically loaded tables.
Provides compatibility with other ACPI implementations. Previously, only
SSDT tables were allowed, as per the ACPI specification. Now, any table
signature can be used via the Load() operator. Lv Zheng.
Tables: Fixed several mutex issues that could cause errors during table
acquisition. Lv Zheng.
Tables: Fixed a problem where an ACPI warning could be generated if a
null pointer was passed to the AcpiPutTable interface. Lv Zheng.
Tables: Added a mechanism to handle imbalances for the AcpiGetTable and
AcpiPutTable interfaces. This applies to the "late stage" table loading
when the use of AcpiPutTable is no longer required (since the system
memory manager is fully running and available). Lv Zheng.
Fixed/Reverted a regression during processing of resource descriptors
that contain only a single EndTag. Fixes an AE_AML_NO_RESOURCE_END_TAG
exception in this case.
Headers: IORT/SMMU support: Updated the SMMU models for Revision C of the
I/O Remapping specification. Robin Murphy <robin.murphy@arm.com>
Interpreter: Fixed a possible fault if an Alias operator with an invalid
or duplicate target is encountered during Alias creation in
AcpiExCreateAlias. Alex James <theracermaster@gmail.com>
Added an option to use designated initializers for function pointers.
Kees Cook <keescook@google.com>
2) iASL Compiler/Disassembler and Tools:
iASL: Allow compilation of External declarations with target pathnames
that refer to existing named objects within the table. Erik Schmauss.
iASL: Fixed a regression when compiling FieldUnits. Fixes an error if a
FieldUnit name also is declared via External in the same table. Erik
Schmauss.
iASL: Allow existing scope names within pathnames used in External
statements. For example:
External (ABCD.EFGH) // ABCD exists, but EFGH is truly external
Device (ABCD)
iASL: IORT ACPI table: Implemented changes required to decode the new
Proximity Domain for the SMMUv3 IORT. Disassembler and Data Table
compiler. Ganapatrao Kulkarni <ganapatrao.kulkarni@cavium.com>
Disassembler: Don't abort disassembly on errors from External()
statements. Erik Schmauss.
Disassembler: fixed a possible fault when one of the Create*Field
operators references a Resource Template. ACPICA Bugzilla 1396.
iASL: In the source code, resolved some naming inconsistences across the
parsing support. Fixes confusion between "Parse Op" and "Parse Node".
Adds a new file, aslparseop.c
----------------------------------------
31 May 2017. Summary of changes for version 20170531:
0) ACPI 6.2 support:
The ACPI specification version 6.2 has been released and is available at
http://uefi.org/specifications
This version of ACPICA fully supports the ACPI 6.2 specification. Changes
are summarized below.
New ACPI tables (Table Compiler/Disassembler/Templates):
HMAT (Heterogeneous Memory Attributes Table)
WSMT (Windows SMM Security Mitigation Table)
PPTT (Processor Properties Topology Table)
New subtables for existing ACPI tables:
HEST (New subtable, Arch-deferred machine check)
SRAT (New subtable, Arch-specific affinity structure)
PCCT (New subtables, Extended PCC subspaces (types 3 and 4))
Simple updates for existing ACPI tables:
BGRT (two new flag bits)
HEST (New bit defined for several subtables, GHES_ASSIST)
New Resource Descriptors and Resource macros (Compiler/Disassembler):
PinConfig()
PinFunction()
PinGroup()
PinGroupConfig()
PinGroupFunction()
New type for hardware error notification (section 18.3.2.9)
New predefined names/methods (Compiler/Interpreter):
_HMA (Heterogeneous Memory Attributes)
_LSI (Label Storage Information)
_LSR (Label Storage Read)
_LSW (Label Storage Write)
ASL grammar/macro changes (Compiler):
For() ASL macro, implemented with the AML while operator
Extensions to Concatenate operator
Support for multiple definition blocks in same ASL file
Clarification for Buffer operator
Allow executable AML code underneath all scopes (Devices, etc.)
Clarification/change for the _OSI return value
ASL grammar update for reference operators
Allow a zero-length string for AML filename in DefinitionBlock
Miscellaneous:
New device object notification value
Remove a notify value (0x0C) for graceful shutdown
New UUIDs for processor/cache properties and
physical package property
New _HID, ACPI0014 (Wireless Power Calibration Device)
1) ACPICA kernel-resident subsystem:
Added support to disable ACPI events on hardware-reduced platforms.
Eliminates error messages of the form "Could not enable fixed event". Lv
Zheng
Fixed a problem using Device/Thermal objects with the ObjectType and
DerefOf ASL operators. This support had not been fully/properly
implemented.
Fixed a problem where if a Buffer object containing a resource template
was longer than the actual resource template, an error was generated --
even though the AML is legal. This case has been seen in the field.
Fixed a problem with the header definition of the MADT PCAT_COMPAT flag.
The values for DUAL_PIC and MULTIPLE_APIC were reversed.
Added header file changes for the TPM2 ACPI table. Update to new version
of the TCG specification. Adds a new TPM2 subtable for ARM SMC.
Exported the external interfaces AcpiAcquireMutex and AcpiReleaseMutex.
These interfaces are intended to be used only in conjunction with the
predefined _DLM method (Device Lock Method). "This object appears in a
device scope when AML access to the device must be synchronized with the
OS environment".
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and
has a much larger code and data size.
Current Release:
Non-Debug Version: 143.1K Code, 60.0K Data, 203.1K Total
Debug Version: 204.0K Code, 84.3K Data, 288.3K Total
Previous Release:
Non-Debug Version: 141.7K Code, 58.5K Data, 200.2K Total
Debug Version: 207.5K Code, 82.7K Data, 290.2K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a problem where an External() declaration could not refer to
a Field Unit. Erik Schmauss.
Disassembler: Improved support for the Switch/Case operators. This
feature will disassemble AML code back to the original Switch operators
when possible, instead of an If..Else sequence. David Box
iASL and disassembler: Improved the handling of multiple extraneous
parentheses for both ASL input and disassembled ASL output.
Improved the behavior of the iASL compiler and disassembler to detect
improper use of external declarations
Disassembler: Now aborts immediately upon detection of an unknown AML
opcode. The AML parser has no real way to recover from this, and can
result in the creation of an ill-formed parse tree that causes errors
later during the disassembly.
All tools: Fixed a problem where the Unix application OSL did not handle
control-c correctly. For example, a control-c could incorrectly wake the
debugger.
AcpiExec: Improved the Control-C handling and added a handler for
segmentation faults (SIGSEGV). Supports both Windows and Unix-like
environments.
Reduced the verbosity of the generic unix makefiles. Previously, each
compilation displayed the full set of compiler options. This has been
eliminated as the options are easily inspected within the makefiles. Each
compilation now results in a single line of output.

----------------------------------------
19 January 2017. Summary of changes for version 20170119:
This release is available at https://acpica.org/downloads
1) General ACPICA software:
Entire source code base: Added the 2017 copyright to all source code
legal/licensing module headers and utility/tool signons. This includes
the standard Linux dual-license header. This affects virtually every file
in the ACPICA core subsystem, iASL compiler, all ACPICA utilities, and
the ACPICA test suite.
2) iASL Compiler/Disassembler and Tools:
iASL: Removed/fixed an inadvertent remark when a method argument
containing a reference is used as a target operand within the method (and
never used as a simple argument), as in the example below. Jeffrey Hugo.
dsdt.asl 1507: Store(0x1, Arg0)
Remark 2146 - ^ Method Argument is never used (Arg0)
All tools: Removed the bit width of the compiler that generated the tool
from the common signon for all user space tools. This proved to be
confusing and unnecessary. This includes similar removal of HARDWARE_NAME
from the generic makefiles (Thomas Petazzoni). Example below.
Old:
ASL+ Optimizing Compiler version 20170119-32
ASL+ Optimizing Compiler version 20170119-64
New:
ASL+ Optimizing Compiler version 20170119
----------------------------------------
22 December 2016. Summary of changes for version 20161222:
1) ACPICA kernel-resident subsystem:
AML Debugger: Implemented a new mechanism to simplify and enhance
debugger integration into all environments, including kernel debuggers
and user-space utilities, as well as remote debug services. This
mechanism essentially consists of new OSL interfaces to support debugger
initialization/termination, as well as wait/notify interfaces to perform
the debugger handshake with the host. Lv Zheng.
New OSL interfaces:
AcpiOsInitializeDebugger (void)
AcpiOsTerminateDebugger (void)
AcpiOsWaitCommandReady (void)
AcpiOsNotifyCommandComplete (void)
New OS services layer:
osgendbg.c -- Example implementation, and used for AcpiExec
Update for Generic Address Space (GAS) support: Although the AccessWidth
and/or BitOffset fields of the GAS are not often used, this change now
fully supports these fields. This affects the internal support for FADT
registers, registers in other ACPI data tables, and the AcpiRead and
AcpiWrite public interfaces. Lv Zheng.
Sleep support: In order to simplify integration of ACPI sleep for the
various host operating systems, a new OSL interface has been introduced.
AcpiOsEnterSleep allows the host to perform any required operations
before the final write to the sleep control register(s) is performed by
ACPICA. Lv Zheng.
New OSL interface:
AcpiOsEnterSleep(SleepState, RegisterAValue, RegisterBValue)
Called from these internal interfaces:
AcpiHwLegacySleep
AcpiHwExtendedSleep
EFI support: Added a very small EFI/ACPICA example application. Provides
a simple demo for EFI integration, as well as assisting with resolution
of issues related to customer ACPICA/EFI integration. Lv Zheng. See:
source/tools/efihello/efihello.c
Local C library: Implemented several new functions to enhance ACPICA
portability, for environments where these clib functions are not
available (such as EFI). Lv Zheng:
putchar
getchar
strpbrk
strtok
memmove
Fixed a regression where occasionally a valid resource descriptor was
incorrectly detected as invalid at runtime, and a
AE_AML_NO_RESOURCE_END_TAG was returned.
Fixed a problem with the recently implemented support that enables
control method invocations as Target operands to many ASL operators.
Warnings of this form: "Needed type [Reference], found [Processor]" were
seen at runtime for some method invocations.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and
has a much larger code and data size.
Current Release:
Non-Debug Version: 141.5K Code, 58.5K Data, 200.0K Total
Debug Version: 201.7K Code, 82.7K Data, 284.4K Total
Previous Release:
Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
Debug Version: 201.3K Code, 82.7K Data, 284.0K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Enhanced output by adding the capability to detect and
disassemble ASL Switch/Case statements back to the original ASL source
code instead of if/else blocks. David Box.
AcpiHelp: Split a large file into separate files based upon
functionality/purpose. New files are:
ahaml.c
ahasl.c
----------------------------------------
17 November 2016. Summary of changes for version 20161117:
1) ACPICA kernel-resident subsystem:
Table Manager: Fixed a regression introduced in 20160729, "FADT support
cleanup". This was an attempt to remove all references in the source to
the FADT version 2, which never was a legal version number. It was
skipped because it was an early version of 64-bit support that was
eventually abandoned for the current 64-bit support.
Interpreter: Fixed a problem where runtime implicit conversion was
incorrectly disabled for the ASL operators below. This brings the
behavior into compliance with the ACPI specification:
FromBCD
ToBCD
ToDecimalString
ToHexString
ToInteger
ToBuffer
Table Manager: Added a new public interface, AcpiPutTable, used to
release and free an ACPI table returned by AcpiGetTable and related
interfaces. Lv Zheng.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and
has a much larger code and data size.
Current Release:
Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
Debug Version: 201.3K Code, 82.7K Data, 284.0K Total
Previous Release:
Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total
Debug Version: 200.7K Code, 82.1K Data, 282.8K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a regression for disassembly of Resource Template.
Detection of templates in the AML stream missed some types of templates.
iASL: Fixed a problem where an Access Size error was returned for the PCC
address space when the AccessSize of the GAS register is greater than a
DWORD. Hoan Tran.
iASL: Implemented several grammar changes for the operators below. These
changes are slated for the next version of the ACPI specification:
RefOf - Disallow method invocation as an operand
CondRefOf - Disallow method invocation as an operand
DerefOf - Disallow operands that use the result from operators
that
do not return a reference (Changed TermArg to
SuperName).
iASL: Control method invocations are now allowed for Target operands, as
per the ACPI specification. Removed error for using a control method
invocation as a Target operand.
Disassembler: Improved detection of Resource Templates, Unicode, and
Strings within Buffer objects. These subtypes do not contain a specific
opcode to indicate the originating ASL code, and they must be detected by
other means within the disassembler.
iASL: Implemented an optimization improvement for 32-bit ACPI tables
(DSDT/SSDT). For the 32-bit case only, compute the optimum integer opcode
only after 64-bit to 32-bit truncation. A truncation warning message is
still emitted, however.
AcpiXtract: Implemented handling for both types of line terminators (LF
or CR/LF) so that it can accept AcpiDump output files from any system.
Peter Wu.
AcpiBin: Added two new options for comparing AML files:
-a: compare and display ALL mismatches
-o: start compare at this offset into the second file
