----------------------------------------
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.

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.

----------------------------------------
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.

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.

----------------------------------------
04 June 2021. Summary of changes for version 20210604:

1) ACPICA kernel-resident subsystem:

Cleaned up (delete) the context mutex during local address handler object
deletion.

Fixed a memory leak caused by the _CID repair function.

Added support for PlatformRtMechanism OperationRegion handler. Adds a new
utility function, AcpiUtConvertUuidToString. Writing a buffer to a
PlatformRtMechanism fieldunit invokes a bidirectional transaction. The
input buffer contains 26 bytes containing 9 bytes of status, a command
byte and a 16-byte UUID. This change will simply pass this incoming
buffer to a handler registered by the OS.

2) iASL Compiler/Disassembler and ACPICA tools:

Added full support for the PRMT ACPI table (Platform Runtime Mechanism
Table). Includes support in the iASL compiler, the disassembler, and the
template generator.

Added full support for the BDAT (BIOS Data ACPI Table) ACPI table.

Added full support for the RGRT (Regulatory Graphics Resource Table) ACPI
table.

Added full support for the SVKL (Storage Volume Key Location Table) ACPI
table. Header file support from Kuppuswamy Sathyanarayanan
<sathyanarayanan.kuppuswamy@linux.intel.com>.

Completed full support for the IVRS (I/O Virtualization Reporting
Structure) ACPI table. Added compiler support for IVRS, updated
disassembler support. Adds a new utility, UtIsIdInteger, to determine if
a HID/CID is an integer or a string.

Headers: Added more structs to the CEDT table: CXL fixed memory window
structure.

ACPI 6.4: MADT: added Multiprocessor Wakeup Mailbox Structure.

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.

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.


----------------------------------------
08 January 2019. Summary of changes for version 20190108:

2) iASL Compiler/Disassembler and Tools:

ASL test suite (ASLTS): Updated all copyrights to 2019.

Tools: Updated all signon copyrights to 2019.

AcpiExec: Added a new option to dump extra information concerning any
memory leaks detected by the internal object/cache tracking mechanism. -

----------------------------------------
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.
