20 October 2022. 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.

17 December 2021. Summary of changes for version 20211217:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Hardware: Do not flush CPU cache when entering S4 and S5. According
to ACPI 6.4, Section 16.2, the CPU cache flushing is required on
entering to S1, S2, and S3, but the ACPICA code flushes the CPU
cache regardless of the sleep state. Blind cache flush on entering
S5 causes problems for TDX.
Avoid subobject buffer overflow when validating RSDP signature.
Since the Signature member is accessed through an ACPI_TABLE_HEADER,
the pointer to it is only to a 4-char array, and so trying to read
past the 4th character, as will be done when it is an RSDP, reads
beyond the bounds of the accessed member. Contributed by jrtc27.
Add support for PCC Opregion special context data. PCC Opregion
added in ACPIC 6.3 requires special context data similar to GPIO
and Generic Serial Bus as it needs to know the internal PCC buffer
and its length as well as the PCC channel index when the opregion
handler is being executed by the OSPM. Adds support for the special
context data needed by PCC Opregion. Submitted by Sudeep Holla
2) iASL Compiler/Disassembler and ACPICA tools:
iASL: Completed compiler support for the NHLT ACPI table.
iASL/NHLT table: Fixed a reported problem where a fault would occur
during disassembly of a "Linux-Specific" section if the "Specific
Data" part was not present.
iASL: Added full support (compiler and disassembler) for the AGDI
ACPI table. Contributed by: Ilkka Koskinen .
iASL: Added full support for the TDEL ACPI table.
iASL table compiler: FADT support updates:
1) Allow the 32-bit DSDT address to be zero.
2) Issue error if both the 32-bit and 64-bit DSDT addresses are zero.
iASL: Fix unaligned accesses to local cache allocations. Contributed
by jrtc27.
iASL: Open binary input files in binary mode, not text mode Affects
binary input AML files, as well as binary data table files, for
disassembly.

christos | 30 September 2021. Summary of changes for version 20210930:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Hardware: Avoid evaluating methods too early during system resume.
During wakeup from system-wide sleep states, AcpiGetSleepTypeData()
is called and it tries to get memory from the OS in order to evaluate
a control method, but if KFENCE is enabled in the Linux kernel,
the memory allocation attempt causes an IRQ work to be queued and
a self-IPI to be sent to the CPU running the code which requires
the memory controller to be ready, so if that happens too early in
the wakeup path, it doesn't work.
Prevent that from taking place by calling AcpiGetSleepTypeData()
for S0 upfront, when preparing to enter a given sleep state, and
saving the data obtained by it for later use during system wakeup.
Added a new _OSI string, "Windows 2020". Posted by superm1.
2) iASL Compiler/Disassembler and ACPICA tools:
iASL compiler: Updated the check for usage of _CRS, _DIS, _PRS, and _SRS objects:
New/latest rules: Under a Device Object:
1) If _PRS is present, must have _CRS and _SRS
2) If _SRS is present, must have _PRS (_PRS requires _CRS and _SRS)
3) If _DIS is present, must have _SRS (_SRS requires _PRS, _PRS requires _CRS
and _SRS)
4) If _SRS is present, probably should have a _DIS (Remark only)
iASL table disassembler: Added disassembly support for the NHLT
ACPI table. Note: support for Vendor-defined microphone arrays and
SNR extensions are not supported at this time -- mostly due to a
lack of example tables. Actual compiler support for NHLT is
forthcoming.
Added a new subtable type for ACPI 6.4 SRAT Generic Port Affinity.
It uses the same subtable structure as the existing Generic Initiator
Affinity type.
Added the flag for online capable in the MADT, introduced in ACPI
6.3. Posted by superm1.
3) ACPICA documentation: Updated the legal info (that appears at
the start of the Documents) to clarify distribution rights that
are granted.
30 July 2021. Summary of changes for version 20210730:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
2) iASL Compiler/Disassembler and ACPICA tools:
iasl: Check usage of _CRS, _DIS, _PRS, and _SRS objects (July 2021).
Under the Device Object:
1) If _DIS is present, must have a _CRS and _SRS
2) If _PRS is present, must have a _CRS, _DIS, and _SRS
3) If _SRS is present, must have a _CRS and _DIS
A warning will be issued for each of these cases.
Note: For existing ASL/projects, these warnings may be disabled by
specifying this on the command line:
"-vw 3141"
iASL Table Disassembler/Table compiler: Fix for WPBT table with no
command-line arguments. Handle the case where the Command-line
Arguments table field does not exist (zero).
Headers: Add new DBG2 Serial Port Subtypes
The Microsoft Debug Port Table 2 (DBG2) specification revision
September 21, 2020 comprises additional Serial Port Subtypes [1].
Reflect that in the actbl1.h header file. Submitted by:
semihalf-wojtas-marcin
iASL: Add full support for the AEST table (data compiler)
Includes support in the table compiler and the disassembler.
Add PRMT module header to facilitate parsing.
This structure is used in to parse PRMT in other Operating Systems
that relies on using subtable headers in order to parse ACPI tables.
Although the PRMT doesn't have "subtables" it has a list of module
information structures that act as subtables.
iASL: Table disassembler: Add missing strings to decode subtable types.
Includes the MADT and CEDT tables.

christos | 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.

| 1.1.1.17 |
| 25-May-2020 |
christos | 30 April 2020. Summary of changes for version 20200430:
1) ACPICA kernel-resident subsystem:
Cleaned up the coding style of a couple of global variables
(AcpiGbl_NextCmdNum and AcpiProtocolLengths) caught by static analyzers.
AcpiProtocolLengths was made static, and the definition of
AcpiGbl_NextCmdNum was moved to acglobal.h.
2) iASL Compiler/Disassembler and ACPICA tools:
iASL DataTable Compiler: Fixed a segfault on errors that aren't directly
associated with a field.
Disassembler: has been made more resilient so that it will continue to
parse AML even if the AML generates ACPI namespace errors. This enables
iASL to disassemble some AML that may have been compiled using older
versions of iASL that no longer compile with newer versions of iASL.
iASL: Fixed the required parameters for _NIH and _NIG. Previously, there
was a mixup where _NIG required one parameter and _NIH required zero
parameters. This change swaps these parameter requirements. Now it is
required that _NIH must be called with one parameter and _NIG requires
zero parameters.
iASL: Allow use of undefined externals as long as they are protected by
an if (CondRefOf (...)) block when compiling multiple definition blocks.
iASL: Fixed the type override behavior of named objects that are declared
as External. External declarations will no longer override the type of
the actual definition if it already exists.
AcpiNames: Added setargv.obj to the MSVC 2017 link sequence to enable
command line wildcard support on Windows. Note: the AcpiNames utility is
essentially redundant with the AcpiExec utility (using the "namespace"
command) and is therefore deprecated. It will be removed in future
releases of ACPICA.
Disassembler: ignore AE_ALREADY_EXISTS status when parsing create*
operators. The disassembler is intended to emit existing ASL code as-is.
Therefore, error messages emitted during disassembly should be ignored or
handled in a way such that the disassembler can continue to parse the
AML. This change ignores AE_ALREADY_EXISTS errors during the deferred Op
parsing for create operators in order to complete parsing ASL termlists.
iASL DataTable Compiler: IVRS table: fix potentially uninitialized
variable warning. Some compilers catch potential uninitialized variables.
This is done by examining branches of if/else statements. This change
replaces an "else if" with an "else" to fix the uninitialized variable
warning.

christos | 13 December 2018. Summary of changes for version 20181213:
1) ACPICA Kernel-resident Subsystem:
Fixed some buffer length issues with the GenericSerialBus, related to two
of the bidirectional protocols: AttribRawProcessBytes and AttribRawBytes,
which are rarely seen in the field. For these, the LEN field of the ASL
buffer is now ignored. Hans de Goede
Implemented a new object evaluation trace mechanism for control methods
and data objects. This includes nested control methods. It is
particularly useful for examining the ACPI execution during system
initialization since the output is relatively terse. The flag below
enables the output of the trace via the ACPI_DEBUG_PRINT_RAW interface:
#define ACPI_LV_EVALUATION 0x00080000
Examples:
Enter evaluation : _SB.PCI0._INI (Method)
Exit evaluation : _SB.PCI0._INI
Enter evaluation : _OSI (Method)
Exit evaluation : _OSI
Enter evaluation : _SB.PCI0.TEST (Method)
Nested method call : _SB.PCI0.NST1
Exit nested method : _SB.PCI0.NST1
Exit evaluation : _SB.PCI0.TEST
Added two recently-defined _OSI strings. See
https://docs.microsoft.com/en-us/windows-hardware/drivers/acpi/winacpi-
osi.
"Windows 2018"
"Windows 2018.2"
Update for buffer-to-string conversions via the ToHexString ASL operator.
A "0x" is now prepended to each of the hex values in the output string.
This provides compatibility with other ACPI implementations. The ACPI
specification is somewhat vague on this issue.
Example output string after conversion:
"0x01,0x02,0x03,0x04,0x05,0x06"
Return a run-time error for TermArg expressions within individual package
elements. Although this is technically supported by the ASL grammar,
other ACPI implementations do not support this either. Also, this fixes a
fault if this type of construct is ever encountered (it never has been).
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented a new compile option (-ww) that will promote individual
warnings and remarks to errors. This is intended to enhance the firmware
build process.
AcpiExec: Implemented a new command-line option (-eo) to support the new
object evaluation trace mechanism described above.
Disassembler: Added support to disassemble OEMx tables as AML/ASL tables
instead of a "unknown table" message.
AcpiHelp: Improved support for the "special" predefined names such as
_Lxx, _Exx, _EJx, _T_x, etc. For these, any legal hex value can now be
used for "xx" and "x".
