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.

13 November 2020. Summary of changes for version 20201113:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Interpreter: fixed a memory leak by using use existing buffer in
_HID repair. There was a memory leak that occurred when a _CID
object is defined as a package containing string objects. When _CID
is checked for any possible repairs, it calls a helper function to
repair _HID (because _CID basically contains multiple _HID entries).
The _HID repair function assumes that string objects are standalone
objects that are not contained inside of any packages. The _HID
repair function replaced the string object with a brand new object
and attempted to delete the old object by decrementing the reference
count of the old object. Strings inside of packages have a reference
count of 2 so the _HID repair function leaves this object in a
dangling state and causes a memory leak. Instead of allocating a
brand new object and removing the old object, use the existing
object when repairing the _HID object.
Added function trace macros to improve namespace debugging. The
namespace repair mechanism does not have function tracing macros.
Add several trace macros to improve debuggability.
Handle "orphan" _REG methods for GPIO OpRegions. Before this change
AcpiEvExecuteRegMethods() had special handling to handle "orphan"
(no matching OpRegion declared) _REG methods for EC nodes. On Intel
Cherry Trail devices there are 2 possible ACPI OpRegions for
accessing GPIOs. The standard GeneralPurposeIo OpRegion and the
Cherry Trail - specific UserDefined 0x9X OpRegions. Having 2
different types of OpRegions leads to potential issues with checks
for OpRegion availability, or in other words checks if _REG has
been called for the OpRegion which the ACPI code wants to use.
Except for the "orphan" EC handling, ACPICA core does not call _REG
on an ACPI node which does not define an OpRegion matching the type
being registered; and the reference design DSDT, from which most
Cherry Trail DSDTs are derived, does not define GeneralPurposeIo,
nor UserDefined(0x93) OpRegions for the GPO2 (UID 3) device, because
no pins were assigned ACPI controlled functions in the reference
design. Together this leads to the perfect storm, at least on the
Cherry Trail based Medion Akayo E1239T. This design does use a GPO2
pin from its ACPI code and has added the Cherry Trail specific
UserDefined(0x93) opregion to its GPO2 ACPI node to access this
pin. But it uses a "has _REG been called" availability check for
the standard GeneralPurposeIo OpRegion. This clearly is a bug in
the DSDT, but this does work under Windows. This issue leads to
the intel vbtn driver reporting the device always being in tablet-mode
at boot, even if it is in laptop mode. Which in turn causes userspace
to ignore touchpad events. So in other words, this issue causes
the touchpad to not work at boot. This change fixes this by extending
the "orphan" _REG method handling to also apply to GPIO address-space
handlers.
2) iASL Compiler/Disassembler and ACPICA tools:
iASL: Added more info to namespace dump file (-ln option). In a
separate section of the dump file (after the main namespace dump),
emit the full pathname for each namespace node, its type, and the
ASL filename and line number where it is declared.
AcpiHelp: Added an option to display/decode iASL exceptions. Option
is: -x [Hex Value] where "Hex Value" is the iASL exception code.
If Hex Value is omitted, all iASL exceptions are displayed.
iASL: Use StringLiteral instead of StringData for some ASL macros.
The use of the stringData rule allows for some "string" oriented
opcodes (Such as ToString, ToHexString, etc.) None of which make
sense with the macros in question. This change modifies the StringData
part of the rule for these macros to a simple string literal - thus
disallowing the use of ToString, ToHexString, etc. The following
ASL operators (macros) are affected: EisaId Fprintf Printf ToUuid
Unicode Note: The MS compiler requires the use of string literals
for these operators also.
iASL: Added a remark for an unknown UUID: ASL_MSG_UUID_NOT_FOUND.
Search the list of "known" UUIDs for the input to the ToUUID macro.
Added 5 new UUIDs to the known UUID table. All related to NVDIMM
and the NFIT table.

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".
