1.1.1.2
log
@----------------------------------------
26 September 2014. Summary of changes for version 20140926:

1) ACPICA kernel-resident subsystem:

Updated the GPIO operation region handler interface (GeneralPurposeIo).
In order to support GPIO Connection objects with multiple pins, along
with the related Field objects, the following changes to the interface
have been made: The Address is now defined to be the offset in bits of
the field unit from the previous invocation of a Connection. It can be
viewed as a "Pin Number Index" into the connection resource descriptor.
The BitWidth is the exact bit width of the field. It is usually one bit,
but not always. See the ACPICA reference guide (section 8.8.6.2.1) for
additional information and examples.

GPE support: During ACPICA/GPE initialization, ensure that all GPEs with
corresponding _Lxx/_Exx methods are disabled (they may have been enabled
by the firmware), so that they cannot fire until they are enabled via
AcpiUpdateAllGpes. Rafael J. Wysocki.

Added a new return flag for the Event/GPE status interfaces --
AcpiGetEventStatus and AcpiGetGpeStatus. The new
ACPI_EVENT_FLAGS_HAS_HANDLER flag is used to indicate that the event or
GPE currently has a handler associated with it, and can thus actually
affect the system. 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:  99.1K Code, 27.3K Data, 126.4K Total
    Debug Version:     192.8K Code, 79.9K Data, 272.7K Total
  Previous Release:
    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a memory allocation/free regression introduced in 20140828
that could cause the compiler to crash. This was introduced inadvertently
during the effort to eliminate compiler memory leaks. ACPICA BZ 1111,
1113.

iASL: Removed two error messages that have been found to create false
positives, until they can be fixed and fully validated (ACPICA BZ 1112):
1) Illegal forward reference within a method
2) Illegal reference across two methods

iASL: Implemented a new option (-lm) to create a hardware mapping file
that summarizes all GPIO, I2C, SPI, and UART connections. This option
works for both the compiler and disassembler. See the iASL compiler user
guide for additional information and examples (section 6.4.6).

AcpiDump: Added support for the version 1 (ACPI 1.0) RSDP in addition to
version 2. This corrects the AE_BAD_HEADER exception seen on systems with
a version 1 RSDP. Lv Zheng ACPICA BZ 1097.

AcpiExec: For Unix versions, don't attempt to put STDIN into raw mode
unless STDIN is actually a terminal. Assists with batch-mode processing.
ACPICA BZ 1114.

Disassembler/AcpiHelp: Added another large group of recognized _HID
values.


----------------------------------------
28 August 2014. Summary of changes for version 20140828:

1) ACPICA kernel-resident subsystem:

Fixed a problem related to the internal use of the Timer() operator where
a 64-bit divide could cause an attempted link to a double-precision math
library. This divide is not actually necessary, so the code was
restructured to eliminate it. Lv Zheng.

ACPI 5.1: Added support for the runtime validation of the _DSD package
(similar to the iASL support).

ACPI 5.1/Headers: Added support for the GICC affinity subtable to the
SRAT table. Hanjun Guo <hanjun.guo@@linaro.org>.

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:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total
  Previous Release:
    Non-Debug Version:  98.7K Code, 27.3K Data, 126.0K Total1
    Debug Version:     192.0K Code, 79.7K Data, 271.7K Total

2) iASL Compiler/Disassembler and Tools:

AcpiExec: Fixed a problem on unix systems where the original terminal
state was not always properly restored upon exit. Seen when using the -v
option. ACPICA BZ 1104.

iASL: Fixed a problem with the validation of the ranges/length within the
Memory24 resource descriptor. There was a boundary condition when the
range was equal to the (length -1) caused by the fact that these values
are defined in 256-byte blocks, not bytes. ACPICA BZ 1098

Disassembler: Fixed a problem with the GpioInt descriptor interrupt
polarity
flags. The flags are actually 2 bits, not 1, and the "ActiveBoth" keyword
is
now supported properly.

ACPI 5.1: Added the GICC affinity subtable to the SRAT table. Supported
in the disassembler, data table compiler, and table template generator.

iASL: Added a requirement for Device() objects that one of either a _HID
or _ADR must exist within the scope of a Device, as per the ACPI
specification. Remove a similar requirement that was incorrectly in place
for the _DSD object.

iASL: Added error detection for illegal named references within control
methods that would cause runtime failures. Now trapped as errors are: 1)
References to objects within a non-parent control method. 2) Forward
references (within a method) -- for control methods, AML interpreters use
a one-pass parse of control methods. ACPICA BZ 1008.

iASL: Added error checking for dependencies related to the _PSx power
methods. ACPICA BZ 1029.
1) For _PS0, one of these must exist within the same scope: _PS1, _PS2,
_PS3.
2) For _PS1, _PS2, and PS3: A _PS0 object must exist within the same
scope.

iASL and table compiler: Cleanup miscellaneous memory leaks by fully
deploying the existing object and string caches and adding new caches for
the table compiler.

iASL: Split the huge parser source file into multiple subfiles to improve
manageability. Generation now requires the M4 macro preprocessor, which
is part of the Bison distribution on both unix and windows platforms.

AcpiSrc: Fixed and removed all extraneous warnings generated during
entire ACPICA source code scan and/or conversion.


----------------------------------------

24 July 2014. Summary of changes for version 20140724:

The ACPI 5.1 specification has been released and is available at:
http://uefi.org/specs/access


0) ACPI 5.1 support in ACPICA:

ACPI 5.1 is fully supported in ACPICA as of this release.

New predefined names. Support includes iASL and runtime ACPICA
validation.
    _CCA (Cache Coherency Attribute).
    _DSD (Device-Specific Data). David Box.

Modifications to existing ACPI tables. Support includes headers, iASL
Data Table compiler, disassembler, and the template generator.
    FADT - New fields and flags. Graeme Gregory.
    GTDT - One new subtable and new fields. Tomasz Nowicki.
    MADT - Two new subtables. Tomasz Nowicki.
    PCCT - One new subtable.

Miscellaneous.
    New notification type for System Resource Affinity change events.


1) ACPICA kernel-resident subsystem:

Fixed a regression introduced in 20140627 where a fault can happen during
the deletion of Alias AML namespace objects. The problem affected both
the core ACPICA and the ACPICA tools including iASL and AcpiExec.

Implemented a new GPE public interface, AcpiMarkGpeForWake. Provides a
simple mechanism to enable wake GPEs that have no associated handler or
control method. Rafael Wysocki.

Updated the AcpiEnableGpe interface to disallow the enable if there is no
handler or control method associated with the particular GPE. This will
help avoid meaningless GPEs and even GPE floods. Rafael Wysocki.

Updated GPE handling and dispatch by disabling the GPE before clearing
the status bit for edge-triggered GPEs. Lv Zheng.

Added Timer() support to the AML Debug object. The current timer value is
now displayed with each invocation of (Store to) the debug object to
enable simple generation of execution times for AML code (method
execution for example.) ACPICA BZ 1093.

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:  98.7K Code, 27.3K Data, 126.0K Total
    Debug Version:     192.0K Code, 79.7K Data, 271.7K Total
  Previous Release:
    Non-Debug Version:  98.7K Code, 27.2K Data, 125.9K Total
    Debug Version:     191.7K Code, 79.6K Data, 271.3K Total


2) iASL Compiler/Disassembler and Tools:

Fixed an issue with the recently added local printf implementation,
concerning width/precision specifiers that could cause incorrect output.
Lv Zheng. ACPICA BZ 1094.

Disassembler: Added support to detect buffers that contain UUIDs and
disassemble them to an invocation of the ToUUID operator. Also emit
commented descriptions of known ACPI-related UUIDs.

AcpiHelp: Added support to display known ACPI-related UUIDs. New option,
-u. Adds three new files.

iASL: Update table compiler and disassembler for DMAR table changes that
were introduced in September 2013. With assistance by David Woodhouse.

----------------------------------------
27 June 2014. Summary of changes for version 20140627:

1) ACPICA kernel-resident subsystem:

Formatted Output: Implemented local versions of standard formatted output
utilities such as printf, etc. Over time, it has been discovered that
there are in fact many portability issues with printf, and the addition
of this feature will fix/prevent these issues once and for all. Some
known issues are summarized below:

1) Output of 64-bit values is not portable. For example, UINT64 is %ull
for the Linux kernel and is %uI64 for some MSVC versions.
2) Invoking printf consistently in a manner that is portable across both
32-bit and 64-bit platforms is difficult at best in many situations.
3) The output format for pointers varies from system to system (leading
zeros especially), and leads to inconsistent output from ACPICA across
platforms.
4) Certain platform-specific printf formats may conflict with ACPICA use.
5) If there is no local C library available, ACPICA now has local support
for printf.

-- To address these printf issues in a complete manner, ACPICA now
directly implements a small subset of printf format specifiers, only
those that it requires. Adds a new file, utilities/utprint.c. Lv Zheng.

Implemented support for ACPICA generation within the EFI environment.
Initially, the AcpiDump utility is supported in the UEFI shell
environment. Lv Zheng.

Added a new external interface, AcpiLogError, to improve ACPICA
portability. This allows the host to redirect error messages from the
ACPICA utilities. Lv Zheng.

Added and deployed new OSL file I/O interfaces to improve ACPICA
portability:
  AcpiOsOpenFile
  AcpiOsCloseFile
  AcpiOsReadFile
  AcpiOsWriteFile
  AcpiOsGetFileOffset
  AcpiOsSetFileOffset
There are C library implementations of these functions in the new file
service_layers/oslibcfs.c -- however, the functions can be implemented by
the local host in any way necessary. Lv Zheng.

Implemented a mechanism to disable/enable ACPI table checksum validation
at runtime. This can be useful when loading tables very early during OS
initialization when it may not be possible to map the entire table in
order to compute the checksum. Lv Zheng.

Fixed a buffer allocation issue for the Generic Serial Bus support.
Originally, a fixed buffer length was used. This change allows for
variable-length buffers based upon the protocol indicated by the field
access attributes. Reported by Lan Tianyu. Lv Zheng.

Fixed a problem where an object detached from a namespace node was not
properly terminated/cleared and could cause a circular list problem if
reattached. ACPICA BZ 1063. David Box.

Fixed a possible recursive lock acquisition in hwregs.c. Rakib Mullick.

Fixed a possible memory leak in an error return path within the function
AcpiUtCopyIobjectToIobject. ACPICA BZ 1087. Colin Ian King.

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:  98.7K Code, 27.2K Data, 125.9K Total
    Debug Version:     191.7K Code, 79.6K Data, 271.3K Total
  Previous Release:
    Non-Debug Version:  96.8K Code, 27.2K Data, 124.0K Total
    Debug Version:     189.5K Code, 79.7K Data, 269.2K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Add dump of ASCII equivalent text within a comment at the
end of each line of the output for the Buffer() ASL operator.

AcpiDump: Miscellaneous changes:
  Fixed repetitive table dump in -n mode.
  For older EFI platforms, use the ACPI 1.0 GUID during RSDP search if
the ACPI 2.0 GUID fails.

iASL: Fixed a problem where the compiler could fault if incorrectly given
an acpidump output file as input. ACPICA BZ 1088. David Box.

AcpiExec/AcpiNames: Fixed a problem where these utilities could fault if
they are invoked without any arguments.

Debugger: Fixed a possible memory leak in an error return path. ACPICA BZ
1086. Colin Ian King.

Disassembler: Cleaned up a block of code that extracts a parent Op
object. Added a comment that explains that the parent is guaranteed to be
valid in this case. ACPICA BZ 1069.

----------------------------------------
24 April 2014. Summary of changes for version 20140424:

1) ACPICA kernel-resident subsystem:

Implemented support to skip/ignore NULL address entries in the RSDT/XSDT.
Some of these tables are known to contain a trailing NULL entry. Lv
Zheng.

Removed an extraneous error message for the case where there are a large
number of system GPEs (> 124). This was the "32-bit FADT register is too
long to convert to GAS struct" message, which is irrelevant for GPEs
since the GPEx_BLK_LEN fields of the FADT are always used instead of the
(limited capacity) GAS bit length. Also, several changes to ensure proper
support for GPE numbers > 255, where some "GPE number" fields were 8-bits
internally.

Implemented and deployed additional configuration support for the public
ACPICA external interfaces. Entire classes of interfaces can now be
easily modified or configured out, replaced by stubbed inline functions
by default. Lv Zheng.

Moved all public ACPICA runtime configuration globals to the public
ACPICA external interface file for convenience. Also, removed some
obsolete/unused globals. See the file acpixf.h. Lv Zheng.

Documentation: Added a new section to the ACPICA reference describing the
maximum number of GPEs that can be supported by the FADT-defined GPEs in
block zero and one. About 1200 total. See section 4.4.1 of the ACPICA
reference.

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:  96.8K Code, 27.2K Data, 124.0K Total
    Debug Version:     189.5K Code, 79.7K Data, 269.2K Total
  Previous Release:
    Non-Debug Version:  97.0K Code, 27.2K Data, 124.2K Total
    Debug Version:     189.7K Code, 79.5K Data, 269.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL and disassembler: Add full support for the LPIT table (Low Power
Idle Table). Includes support in the disassembler, data table compiler,
and template generator.

AcpiDump utility:
1) Add option to force the use of the RSDT (over the XSDT).
2) Improve validation of the RSDP signature (use 8 chars instead of 4).

iASL: Add check for predefined packages that are too large.  For
predefined names that contain subpackages, check if each subpackage is
too large. (Check for too small already exists.)

Debugger: Updated the GPE command (which simulates a GPE by executing the
GPE code paths in ACPICA). The GPE device is now optional, and defaults
to the GPE 0/1 FADT-defined blocks.

Unix application OSL: Update line-editing support. Add additional error
checking and take care not to reset terminal attributes on exit if they
were never set. This should help guarantee that the terminal is always
left in the previous state on program exit.

----------------------------------------
25 March 2014. Summary of changes for version 20140325:

1) ACPICA kernel-resident subsystem:

Updated the auto-serialize feature for control methods. This feature
automatically serializes all methods that create named objects in order
to prevent runtime errors. The update adds support to ignore the
currently executing AML SyncLevel when invoking such a method, in order
to prevent disruption of any existing SyncLevel priorities that may exist
in the AML code. Although the use of SyncLevels is relatively rare, this
change fixes a regression where an AE_AML_MUTEX_ORDER exception can
appear on some machines starting with the 20140214 release.

Added a new external interface to allow the host to install ACPI tables
very early, before the namespace is even created. AcpiInstallTable gives
the host additional flexibility for ACPI table management. Tables can be
installed directly by the host as if they had originally appeared in the
XSDT/RSDT. Installed tables can be SSDTs or other ACPI data tables
(anything except the DSDT and FACS). Adds a new file, tbdata.c, along
with additional internal restructuring and cleanup. See the ACPICA
Reference for interface details. Lv Zheng.

Added validation of the checksum for all incoming dynamically loaded
tables (via external interfaces or via AML Load/LoadTable operators). Lv
Zheng.

Updated the use of the AcpiOsWaitEventsComplete interface during Notify
and GPE handler removal. Restructured calls to eliminate possible race
conditions. Lv Zheng.

Added a warning for the use/execution of the ASL/AML Unload (table)
operator. This will help detect and identify machines that use this
operator if and when it is ever used. This operator has never been seen
in the field and the usage model and possible side-effects of the drastic
runtime action of a full table removal are unknown.

Reverted the use of #pragma push/pop which was introduced in the 20140214
release. It appears that push and pop are not implemented by enough
compilers to make the use of this feature feasible for ACPICA at this
time. However, these operators may be deployed in a future ACPICA
release.

Added the missing EXPORT_SYMBOL macros for the install and remove SCI
handler interfaces.

Source code generation:
1) Disabled the use of the "strchr" macro for the gcc-specific
generation. For some versions of gcc, this macro can periodically expose
a compiler bug which in turn causes compile-time error(s).
2) Added support for PPC64 compilation. Colin Ian King.

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:  97.0K Code, 27.2K Data, 124.2K Total
    Debug Version:     189.7K Code, 79.5K Data, 269.2K Total
  Previous Release:
    Non-Debug Version:  96.5K Code, 27.2K Data, 123.7K Total
    Debug Version:     188.6K Code, 79.0K Data, 267.6K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Added several new features to improve the readability of
the resulting ASL code. Extra information is emitted within comment
fields in the ASL code:
1) Known _HID/_CID values are decoded to descriptive text.
2) Standard values for the Notify() operator are decoded to descriptive
text.
3) Target operands are expanded to full pathnames (in a comment) when
possible.

Disassembler: Miscellaneous updates for extern() handling:
1) Abort compiler if file specified by -fe option does not exist.
2) Silence unnecessary warnings about argument count mismatches.
3) Update warning messages concerning unresolved method externals.
4) Emit "UnknownObj" keyword for externals whose type cannot be
determined.

AcpiHelp utility:
1) Added the -a option to display both the ASL syntax and the AML
encoding for an input ASL operator. This effectively displays all known
information about an ASL operator with one AcpiHelp invocation.
2) Added substring match support (similar to a wildcard) for the -i
(_HID/PNP IDs) option.

iASL/Disassembler: Since this tool does not yet support execution on big-
endian machines, added detection of endianness and an error message if
execution is attempted on big-endian. Support for big-endian within iASL
is a feature that is on the ACPICA to-be-done list.

AcpiBin utility:
1) Remove option to extract binary files from an acpidump; this function
is made obsolete by the AcpiXtract utility.
2) General cleanup of open files and allocated buffers.

----------------------------------------
14 February 2014. Summary of changes for version 20140214:

1) ACPICA kernel-resident subsystem:

Implemented a new mechanism to proactively prevent problems with ill-
behaved reentrant control methods that create named ACPI objects. This
behavior is illegal as per the ACPI specification, but is nonetheless
frequently seen in the field. Previously, this could lead to an
AE_ALREADY_EXISTS exception if the method was actually entered by more
than one thread. This new mechanism detects such methods at table load
time and marks them "serialized" to prevent reentrancy. A new global
option, AcpiGbl_AutoSerializeMethods, has been added to disable this
feature if desired. This mechanism and global option obsoletes and
supersedes the previous AcpiGbl_SerializeAllMethods option.

Added the "Windows 2013" string to the _OSI support. ACPICA will now
respond TRUE to _OSI queries with this string. It is the stated policy of
ACPICA to add new strings to the _OSI support as soon as possible after
they are defined. See the full ACPICA _OSI policy which has been added to
the utilities/utosi.c file.

Hardened/updated the _PRT return value auto-repair code:
1) Do not abort the repair on a single subpackage failure, continue to
check all subpackages.
2) Add check for the minimum subpackage length (4).
3) Properly handle extraneous NULL package elements.

Added support to avoid the possibility of infinite loops when traversing
object linked lists. Never allow an infinite loop, even in the face of
corrupted object lists.

ACPICA headers: Deployed the use of #pragma pack(push) and #pragma
pack(pop) directives to ensure that the ACPICA headers are independent of
compiler settings or other host headers.

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:  96.5K Code, 27.2K Data, 123.7K Total
    Debug Version:     188.6K Code, 79.0K Data, 267.6K Total
  Previous Release:
    Non-Debug Version:  96.2K Code, 27.0K Data, 123.2K Total
    Debug Version:     187.5K Code, 78.3K Data, 265.8K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Table-compiler: Fixed a problem with support for the SPMI table. The
first reserved field was incorrectly forced to have a value of zero. This
change correctly forces the field to have a value of one. ACPICA BZ 1081.

Debugger: Added missing support for the "Extra" and "Data" subobjects
when displaying object data.

Debugger: Added support to display entire object linked lists when
displaying object data.

iASL: Removed the obsolete -g option to obtain ACPI tables from the
Windows registry. This feature has been superseded by the acpidump
utility.

----------------------------------------
14 January 2014. Summary of changes for version 20140114:

1) ACPICA kernel-resident subsystem:

Updated all ACPICA copyrights and signons to 2014. Added the 2014
copyright to all module headers and signons, including the standard Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, all ACPICA utilities, and the test suites.

Improved parameter validation for AcpiInstallGpeBlock. Added the
following checks:
1) The incoming device handle refers to type ACPI_TYPE_DEVICE.
2) There is not already a GPE block attached to the device.
Likewise, with AcpiRemoveGpeBlock, ensure that the incoming object is a
device.

Correctly support "references" in the ACPI_OBJECT. This change fixes the
support to allow references (namespace nodes) to be passed as arguments
to control methods via the evaluate object interface. This is probably
most useful for testing purposes, however.

Improved support for 32/64 bit physical addresses in printf()-like
output. This change improves the support for physical addresses in printf
debug statements and other output on both 32-bit and 64-bit hosts. It
consistently outputs the appropriate number of bytes for each host. The
%p specifier is unsatisfactory since it does not emit uniform output on
all hosts/clib implementations (on some, leading zeros are not supported,
leading to difficult-to-read output).

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:  96.2K Code, 27.0K Data, 123.2K Total
    Debug Version:     187.5K Code, 78.3K Data, 265.8K Total
  Previous Release:
    Non-Debug Version:  96.1K Code, 27.0K Data, 123.1K Total
    Debug Version:     185.6K Code, 77.3K Data, 262.9K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fix a possible fault when using the Connection() operator. Fixes a
problem if the parent Field definition for the Connection operator refers
to an operation region that does not exist. ACPICA BZ 1064.

AcpiExec: Load of local test tables is now optional. The utility has the
capability to load some various tables to test features of ACPICA.
However, there are enough of them that the output of the utility became
confusing. With this change, only the required local tables are displayed
(RSDP, XSDT, etc.) along with the actual tables loaded via the command
line specification. This makes the default output simler and easier to
understand. The -el command line option restores the original behavior
for testing purposes.

AcpiExec: Added support for overlapping operation regions. This change
expands the simulation of operation regions by supporting regions that
overlap within the given address space. Supports SystemMemory and
SystemIO. ASLTS test suite updated also. David Box. ACPICA BZ 1031.

AcpiExec: Added region handler support for PCI_Config and EC spaces. This
allows AcpiExec to simulate these address spaces, similar to the current
support for SystemMemory and SystemIO.

Debugger: Added new command to read/write/compare all namespace objects.
The command "test objects" will exercise the entire namespace by writing
new values to each data object, and ensuring that the write was
successful. The original value is then restored and verified.

Debugger: Added the "test predefined" command. This change makes this
test public and puts it under the new "test" command. The test executes
each and every predefined name within the current namespace.

10 April 2015. Summary of changes for version 20150410:

Reverted a change introduced in version 20150408 that caused
a regression in the disassembler where incorrect operator
symbols could be emitted.

----------------------------------------
08 April 2015. Summary of changes for version 20150408:


1) ACPICA kernel-resident subsystem:

Permanently set the return value for the _REV predefined name. It now
returns 2 (was 5). This matches other ACPI implementations. _REV will be
deprecated in the future, and is now defined to be 1 for ACPI 1.0, and 2
for ACPI 2.0 and later. It should never be used to differentiate or
identify operating systems.

Added the "Windows 2015" string to the _OSI support. ACPICA will now
return TRUE to a query with this string.

Fixed several issues with the local version of the printf function.

Added the C99 compiler option (-std=c99) to the Unix makefiles.

  Current Release:
    Non-Debug Version:  99.9K Code, 27.4K Data, 127.3K Total
    Debug Version:     195.2K Code, 80.7K Data, 275.9K Total
  Previous Release:
    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented an enhancement to the constant folding feature to
transform the parse tree to a simple Store operation whenever possible:
    Add (2, 3, X) ==> is converted to: Store (5, X)
    X = 2 + 3     ==> is converted to: Store (5, X)

Updated support for the SLIC table (Software Licensing Description Table)
in both the Data Table compiler and the disassembler. The SLIC table
support now conforms to "Microsoft Software Licensing Tables (SLIC and
MSDM). November 29, 2011. Copyright 2011 Microsoft". Note: Any SLIC data
following the ACPI header is now defined to be "Proprietary Data", and as
such, can only be entered or displayed as a hex data block.

Implemented full support for the MSDM table as described in the document
above. Note: The format of MSDM is similar to SLIC. Any MSDM data
following the ACPI header is defined to be "Proprietary Data", and can
only be entered or displayed as a hex data block.

Implemented the -Pn option for the iASL Table Compiler (was only
implemented for the ASL compiler). This option disables the iASL
preprocessor.

Disassembler: For disassembly of Data Tables, added a comment field
around the Ascii equivalent data that is emitted as part of the "Raw
Table Data" block. This prevents the iASL Preprocessor from possible
confusion if/when the table is compiled.

Disassembler: Added an option (-df) to force the disassembler to assume
that the table being disassembled contains valid AML. This feature is
useful for disassembling AML files that contain ACPI signatures other
than DSDT or SSDT (such as OEMx or other signatures).

Changes for the EFI version of the tools:
1) Fixed a build error/issue
2) Fixed a cast warning

iASL: Fixed a path issue with the __FILE__ operator by making the
directory prefix optional within the internal SplitInputFilename
function.

Debugger: Removed some unused global variables.

Tests: Updated the makefile for proper generation of the AAPITS suite.

----------------------------------------
04 February 2015. Summary of changes for version 20150204:

ACPICA kernel-resident subsystem:

Updated all ACPICA copyrights and signons to 2014. Added the 2014
copyright to all module headers and signons, including the standard Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, all ACPICA utilities, and the test suites.

Events: Introduce ACPI_GPE_DISPATCH_RAW_HANDLER to fix GPE storm issues.
A raw gpe handling mechanism was created to allow better handling of GPE
storms that aren't easily managed by the normal handler. The raw handler
allows disabling/renabling of the the GPE so that interrupt storms can be
avoided in cases where events cannot be timely serviced. In this
scenario, handlers should use the AcpiSetGpe() API to disable/enable the
GPE. This API will leave the reference counts undisturbed, thereby
preventing unintentional clearing of the GPE when the intent in only to
temporarily disable it. Raw handlers allow enabling and disabling of a
GPE by removing GPE register locking. As such, raw handlers much provide
their own locks while using GPE API's to protect access to GPE data
structures.
Lv Zheng

Events: Always modify GPE registers under the GPE lock.
Applies GPE lock around AcpiFinishGpe() to protect access to GPE register
values. Reported as bug by joe.liu@@apple.com.

Unix makefiles: Separate option to disable optimizations and
_FORTIFY_SOURCE. This change removes the _FORTIFY_SOURCE flag from the
NOOPT disable option and creates a separate flag (NOFORTIFY) for this
purpose. Some toolchains may define _FORTIFY_SOURCE which leads redefined
errors when building ACPICA. This allows disabling the option without
also having to disable optimazations.

----------------------------------------
07 November 2014. Summary of changes for version 20141107:

This release is available at https://acpica.org/downloads

This release introduces and implements language extensions to ASL that
provide support for symbolic ("C-style") operators and expressions. These
language extensions are known collectively as ASL+.


1) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with disassembly of the UartSerialBus
macro. Changed "StopBitsNone" to the correct "StopBitsZero". David E.
Box.

Disassembler: Fixed the Unicode macro support to add escape sequences.
All non-printable ASCII values are emitted as escape sequences, as well
as the standard escapes for quote and backslash. Ensures that the
disassembled macro can be correctly recompiled.

iASL: Added Printf/Fprintf macros for formatted output. These macros are
translated to existing AML Concatenate and Store operations. Printf
writes to the ASL Debug object. Fprintf allows the specification of an
ASL name as the target. Only a single format specifier is required, %o,
since the AML interpreter dynamically converts objects to the required
type. David E. Box.

    (old)    Store (Concatenate (Concatenate (Concatenate (Concatenate
                 (Concatenate (Concatenate (Concatenate ("", Arg0),
                 ": Unexpected value for "), Arg1), ", "), Arg2),
                 " at line "), Arg3), Debug)

    (new)    Printf ("%o: Unexpected value for %o, %o at line %o",
                 Arg0, Arg1, Arg2, Arg3)

    (old)    Store (Concatenate (Concatenate (Concatenate (Concatenate
                 ("", Arg1), ": "), Arg0), " Successful"), STR1)

    (new)    Fprintf (STR1, "%o: %o Successful", Arg1, Arg0)

iASL: Added debug options (-bp, -bt) to dynamically prune levels of the
ASL parse tree before the AML code is generated. This allows blocks of
ASL code to be removed in order to help locate and identify problem
devices and/or code. David E. Box.

AcpiExec: Added support (-fi) for an optional namespace object
initialization file. This file specifies initial values for namespace
objects as necessary for debugging and testing different ASL code paths
that may be taken as a result of BIOS options.


2) Overview of symbolic operator support for ASL (ASL+)
-------------------------------------------------------

As an extension to the ASL language, iASL implements support for symbolic
(C-style) operators for math and logical expressions. This can greatly
simplify ASL code as well as improve both readability and
maintainability. These language extensions can exist concurrently with
all legacy ASL code and expressions.

The symbolic extensions are 100% compatible with existing AML
interpreters, since no new AML opcodes are created. To implement the
extensions, the iASL compiler transforms the symbolic expressions into
the legacy ASL/AML equivalents at compile time.

Full symbolic expressions are supported, along with the standard C
precedence and associativity rules.

Full disassembler support for the symbolic expressions is provided, and
creates an automatic migration path for existing ASL code to ASL+ code
via the disassembly process. By default, the disassembler now emits ASL+
code with symbolic expressions. An option (-dl) is provided to force the
disassembler to emit legacy ASL code if desired.

Below is the complete list of the currently supported symbolic operators
with examples. See the iASL User Guide for additional information.


ASL+ Syntax      Legacy ASL Equivalent
-----------      ---------------------

    // Math operators

Z = X + Y        Add (X, Y, Z)
Z = X - Y        Subtract (X, Y, Z)
Z = X * Y        Multiply (X, Y, Z)
Z = X / Y        Divide (X, Y, , Z)
Z = X % Y        Mod (X, Y, Z)
Z = X << Y       ShiftLeft (X, Y, Z)
Z = X >> Y       ShiftRight (X, Y, Z)
Z = X & Y        And (X, Y, Z)
Z = X | Y        Or (X, Y, Z)
Z = X ^ Y        Xor (X, Y, Z)
Z = ~X           Not (X, Z)
X++              Increment (X)
X--              Decrement (X)

    // Logical operators

(X == Y)         LEqual (X, Y)
(X != Y)         LNotEqual (X, Y)
(X < Y)          LLess (X, Y)
(X > Y)          LGreater (X, Y)
(X <= Y)         LLessEqual (X, Y)
(X >= Y)         LGreaterEqual (X, Y)
(X && Y)         LAnd (X, Y)
(X || Y)         LOr (X, Y)
(!X)             LNot (X)

    // Assignment and compound assignment operations

X = Y           Store (Y, X)
X += Y          Add (X, Y, X)
X -= Y          Subtract (X, Y, X)
X *= Y          Multiply (X, Y, X)
X /= Y          Divide (X, Y, , X)
X %= Y          Mod (X, Y, X)
X <<= Y         ShiftLeft (X, Y, X)
X >>= Y         ShiftRight (X, Y, X)
X &= Y          And (X, Y, X)
X |= Y          Or (X, Y, X)
X ^= Y          Xor (X, Y, X)


3) ASL+ Examples:
-----------------

Legacy ASL:
        If (LOr (LOr (LEqual (And (R510, 0x03FB), 0x02E0), LEqual (
            And (R520, 0x03FB), 0x02E0)), LOr (LEqual (And (R530,
0x03FB),
            0x02E0), LEqual (And (R540, 0x03FB), 0x02E0))))
        {
            And (MEMB, 0xFFFFFFF0, SRMB)
            Store (MEMB, Local2)
            Store (PDBM, Local1)
            And (PDBM, 0xFFFFFFFFFFFFFFF9, PDBM)
            Store (SRMB, MEMB)
            Or (PDBM, 0x02, PDBM)
        }

ASL+ version:
        If (((R510 & 0x03FB) == 0x02E0) ||
            ((R520 & 0x03FB) == 0x02E0) ||
            ((R530 & 0x03FB) == 0x02E0) ||
            ((R540 & 0x03FB) == 0x02E0))
        {
            SRMB = (MEMB & 0xFFFFFFF0)
            Local2 = MEMB
            Local1 = PDBM
            PDBM &= 0xFFFFFFFFFFFFFFF9
            MEMB = SRMB
            PDBM |= 0x02
        }

Legacy ASL:
        Store (0x1234, Local1)
        Multiply (Add (Add (Local1, TEST), 0x20), Local2, Local3)
        Multiply (Local2, Add (Add (Local1, TEST), 0x20), Local3)
        Add (Local1, Add (TEST, Multiply (0x20, Local2)), Local3)
        Store (Index (PKG1, 0x03), Local6)
        Store (Add (Local3, Local2), Debug)
        Add (Local1, 0x0F, Local2)
        Add (Local1, Multiply (Local2, Local3), Local2)
        Multiply (Add (Add (Local1, TEST), 0x20), ToBCD (Local1), Local3)

ASL+ version:
        Local1 = 0x1234
        Local3 = (((Local1 + TEST) + 0x20) * Local2)
        Local3 = (Local2 * ((Local1 + TEST) + 0x20))
        Local3 = (Local1 + (TEST + (0x20 * Local2)))
        Local6 = Index (PKG1, 0x03)
        Debug = (Local3 + Local2)
        Local2 = (Local1 + 0x0F)
        Local2 = (Local1 + (Local2 * Local3))
        Local3 = (((Local1 + TEST) + 0x20) * ToBCD (Local1))

1.1.1.4
log
@----------------------------------------
17 July 2015. Summary of changes for version 20150717:

1) ACPICA kernel-resident subsystem:

Improved the partitioning between the Debugger and Disassembler
components. This allows the Debugger to be used standalone within kernel
code without the Disassembler (which is used for single stepping also).
This renames and moves one file, dmobject.c to dbobject.c. Lv Zheng.

Debugger: Implemented a new command to trace the execution of control
methods (Trace). This is especially useful for the in-kernel version of
the debugger when file I/O may not be available for method trace output.
See the ACPICA reference for more information. Lv Zheng.

Moved all C library prototypes (used for the local versions of these
functions when requested) to a new header, acclib.h
Cleaned up the use of non-ANSI C library functions. These functions are
implemented locally in ACPICA. Moved all such functions to a common
source file, utnonansi.c

Debugger: Fixed a problem with the "!!" command (get last command
executed) where the debugger could enter an infinite loop and eventually
crash.

Removed the use of local macros that were used for some of the standard C
library functions to automatically cast input parameters. This mostly
affected the is* functions where the input parameter is defined to be an
int. This required a few modifications to the main ACPICA source code to
provide casting for these functions and eliminate possible compiler
warnings for these parameters.

Across the source code, added additional status/error checking to resolve
issues discovered by static source code analysis tools such as Coverity.

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: 100.9K Code, 24.5K Data, 125.4K Total
    Debug Version:     197.8K Code, 81.5K Data, 279.3K Total
  Previous Release:
    Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total
    Debug Version:     196.2K Code, 81.0K Data, 277.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a regression where the device map file feature no longer
worked properly when used in conjunction with the disassembler. It only
worked properly with the compiler itself.

iASL: Implemented a new warning for method LocalX variables that are set
but never used (similar to a C compiler such as gcc). This also applies
to ArgX variables that are not defined by the parent method, and are
instead (legally) used as local variables.

iASL/Preprocessor: Finished the pass-through of line numbers from the
preprocessor to the compiler. This ensures that compiler errors/warnings
have the correct original line numbers and filenames, regardless of any
#include files.

iASL/Preprocessor: Fixed a couple of issues with comment handling and the
pass-through of comments to the preprocessor output file (which becomes
the compiler input file). Also fixed a problem with // comments that
appear after a math expression.

iASL: Added support for the TCPA server table to the table compiler and
template generator. (The client table was already previously supported)

iASL/Preprocessor: Added a permanent #define of the symbol "__IASL__" to
identify the iASL compiler.

Cleaned up the use of the macros NEGATIVE and POSITIVE which were defined
multiple times. The new names are ACPI_SIGN_NEGATIVE and
ACPI_SIGN_POSITIVE.

AcpiHelp: Update to expand help messages for the iASL preprocessor
directives.


----------------------------------------
19 June 2015. Summary of changes for version 20150619:

Two regressions in version 20150616 have been addressed:

Fixes some problems/issues with the C library macro removal (ACPI_STRLEN,
etc.) This update changes ACPICA to only use the standard headers for
functions, or the prototypes for the local versions of the C library
functions. Across the source code, this required some additional casts
for some Clib invocations for portability. Moved all local prototypes to
a new file, acclib.h

Fixes several problems with recent changes to the handling of the FACS
table that could cause some systems not to boot.


----------------------------------------
16 June 2015. Summary of changes for version 20150616:


1) ACPICA kernel-resident subsystem:

Across the entire ACPICA source code base, the various macros for the C
library functions (such as ACPI_STRLEN, etc.) have been removed and
replaced by the standard C library names (strlen, etc.) The original
purpose for these macros is no longer applicable. This simplification
reduces the number of macros used in the ACPICA source code
significantly, improving readability and maintainability.

Implemented support for a new ACPI table, the OSDT. This table, the
"override" SDT, can be loaded directly by the host OS at boot time. It
enables the replacement of existing namespace objects that were installed
via the DSDT and/or SSDTs. The primary purpose for this is to replace
buggy or incorrect ASL/AML code obtained via the BIOS. The OSDT is slated
for inclusion in a future version of the ACPI Specification. Lv Zheng/Bob
Moore.

Added support for systems with (improperly) two FACS tables -- a "32-bit"
table (via FADT 32-bit legacy field) and a "64-bit" table (via the 64-bit
X field). This change will support both automatically. There continues to
be systems found with this issue. This support requires a change to the
AcpiSetFirmwareWakingVector interface. Also, a public global variable has
been added to allow the host to select which FACS is desired
(AcpiGbl_Use32BitFacsAddresses). See the ACPICA reference for more
details Lv Zheng.

Added a new feature to allow for systems that do not contain an FACS.
Although this is already supported on hardware-reduced platforms, the
feature has been extended for all platforms. The reasoning is that we do
not want to abort the entire ACPICA initialization just because the
system is seriously buggy and has no FACS.

Fixed a problem where the GUID strings for NFIT tables (in acuuid.h) were
not correctly transcribed from the ACPI specification in ACPICA version
20150515.

Implemented support for the _CLS object in the AcpiGetObjectInfo external
interface.

Updated the definitions of the TCPA and TPM2 ACPI tables to the more
recent TCG ACPI Specification, December 14, 2014. Table disassembler and
compiler also updated. Note: The TCPA "server" table is not supported by
the disassembler/table-compiler at this time.

ACPI 6.0: Added definitions for the new GIC version field in the MADT.

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: 100.6K Code, 27.6K Data, 128.2K Total
    Debug Version:     196.2K Code, 81.0K Data, 277.2K Total
  Previous Release:
    Non-Debug Version:  99.9K Code, 27.5K Data, 127.4K Total
    Debug Version:     195.2K Code, 80.8K Data, 276.0K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with the new symbolic operator disassembler
where incorrect ASL code could be emitted in some cases for the "non-
commutative" operators -- Subtract, Divide, Modulo, ShiftLeft, and
ShiftRight. The actual problem cases seem to be rather unusual in common
ASL code, however. David Box.

Modified the linux version of acpidump to obtain ACPI tables from not
just /dev/mem (which may not exist) and /sys/firmware/acpi/tables. Lv
Zheng.

iASL: Fixed a problem where the user preprocessor output file (.i)
contained extra data that was not expected. The compiler was using this
file as a temporary file and passed through #line directives in order to
keep compiler error messages in sync with the input file and line number
across multiple include files. The (.i) is no longer a temporary file as
the compiler uses a new, different file for the original purpose.

iASL: Fixed a problem where comments within the original ASL source code
file were not passed through to the preprocessor output file, nor any
listing files.

iASL: Fixed some issues for the handling of the "#include" preprocessor
directive and the similar (but not the same) "Include" ASL operator.

iASL: Add support for the new OSDT in both the disassembler and compiler.

iASL: Fixed a problem with the constant folding support where a Buffer
object could be incorrectly generated (incorrectly formed) during a
conversion to a Store() operator.

AcpiHelp: Updated for new NFIT GUIDs, "External" AML opcode, and new
description text for the _REV predefined name. _REV now permanently
returns 2, as per the ACPI 6.0 specification.

Debugger: Enhanced the output of the Debug ASL object for references
produced by the Index operator. For Buffers and strings, only output the
actual byte pointed to by the index. For packages, only print the single
package element decoded by the index. Previously, the entire
buffer/string/package was emitted.

iASL/Table-compiler: Fixed a regression where the "generic" data types
were no longer recognized, causing errors.


----------------------------------------
15 May 2015. Summary of changes for version 20150515:

This release implements most of ACPI 6.0 as described below.

1) ACPICA kernel-resident subsystem:

Implemented runtime argument checking and return value checking for all
new ACPI 6.0 predefined names. This includes: _BTH, _CR3, _DSD, _LPI,
_MTL, _PRR, _RDI, _RST, _TFP, _TSN.

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:  99.9K Code, 27.5K Data, 127.4K Total
    Debug Version:     195.2K Code, 80.8K Data, 276.0K Total
  Previous Release:
    Non-Debug Version:  99.1K Code, 27.3K Data, 126.4K Total
    Debug Version:     192.8K Code, 79.9K Data, 272.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL compiler: Added compile-time support for all new ACPI 6.0 predefined
names (argument count validation and return value typechecking.)

iASL disassembler and table compiler: implemented support for all new
ACPI 6.0 tables. This includes: DRTM, IORT, LPIT, NFIT, STAO, WPBT, XENV.

iASL disassembler and table compiler: Added ACPI 6.0 changes to existing
tables: FADT, MADT.

iASL preprocessor: Added a new directive to enable inclusion of binary
blobs into ASL code. The new directive is #includebuffer. It takes a
binary file as input and emits a named ascii buffer object into the ASL
code.

AcpiHelp: Added support for all new ACPI 6.0 predefined names.

AcpiHelp: Added a new option, -d, to display all iASL preprocessor
directives.

AcpiHelp: Added a new option, -t, to display all known/supported ACPI
tables.

1.1.1.5
log
@22 April 2016. Summary of changes for version 20160422:

1) ACPICA kernel-resident subsystem:

Fixed a regression in the GAS (generic address structure) arbitrary bit
support in AcpiHwRead/AcpiHwWrite. Problem could cause incorrect behavior
and incorrect return values. Lv Zheng. ACPICA BZ 1270.

ACPI 6.0: Added support for new/renamed resource macros. One new argument
was added to each of these macros, and the original name has been
deprecated. The AML disassembler will always disassemble to the new
names. Support for the new macros was added to iASL, disassembler,
resource manager, and the acpihelp utility. ACPICA BZ 1274.

    I2cSerialBus  -> I2cSerialBusV2
    SpiSerialBus  -> SpiSerialBusV2
    UartSerialBus -> UartSerialBusV2

ACPI 6.0: Added support for a new integer field that was appended to the
package object returned by the _BIX method. This adds iASL compile-time
and AML runtime error checking. ACPICA BZ 1273.

ACPI 6.1: Added support for a new PCCT subtable, "HW-Reduced Comm
Subspace Type2" (Headers, Disassembler, and data table compiler).

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: 137.4K Code, 52.6K Data, 190.0K Total
    Debug Version:     201.5K Code, 82.2K Data, 283.7K Total
  Previous Release:
    Non-Debug Version: 137.1K Code, 51.5K Data, 188.6K Total
    Debug Version:     201.0K Code, 82.0K Data, 283.0K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented an ASL grammar extension to allow/enable executable
"module-level code" to be created and executed under the various
operators that create new scopes. This type of AML code is already
supported in all known AML interpreters, and the grammar change will
appear in the next version of the ACPI specification. Simplifies the
conditional runtime creation of named objects under these object types:

    Device
    PowerResource
    Processor
    Scope
    ThermalZone

iASL: Implemented a new ASL extension, a "For" loop macro to add greater
ease-of-use to the ASL language. The syntax is similar to the
corresponding C operator, and is implemented with the existing AML While
opcode -- thus requiring no changes to existing AML interpreters.

    For (Initialize, Predicate, Update) {TermList}

Grammar:
    ForTerm :=
        For (
            Initializer    // Nothing | TermArg => ComputationalData
            Predicate      // Nothing | TermArg => ComputationalData
            Update         // Nothing | TermArg => ComputationalData
        ) {TermList}


iASL: The _HID/_ADR detection and validation has been enhanced to search
under conditionals in order to allow these objects to be conditionally
created at runtime.

iASL: Fixed several issues with the constant folding feature. The
improvement allows better detection and resolution of statements that can
be folded at compile time. ACPICA BZ 1266.

iASL/Disassembler: Fixed a couple issues with the Else{If{}...}
conversion to the ASL ElseIf operator where incorrect ASL code could be
generated.

iASL/Disassembler: Fixed a problem with the ASL+ code disassembly where
sometimes an extra (and extraneous) set of parentheses were emitted for
some combinations of operators. Although this did not cause any problems
with recompilation of the disassembled code, it made the code more
difficult to read. David Box. ACPICA BZ 1231.

iASL: Changed to ignore the unreferenced detection for predefined names
of resource descriptor elements, when the resource descriptor is
created/defined within a control method.

iASL: Disassembler: Fix a possible fault with externally declared Buffer
objects.

----------------------------------------
18 March 2016. Summary of changes for version 20160318:

1) ACPICA kernel-resident subsystem:

Added support for arbitrary bit lengths and bit offsets for registers
defined by the Generic Address Structure. Previously, only aligned bit
lengths of 8/16/32/64 were supported. This was sufficient for many years,
but recently some machines have been seen that require arbitrary bit-
level support. ACPICA BZ 1240. Lv Zheng.

Fixed an issue where the \_SB._INI method sometimes must be evaluated
before any _REG methods are evaluated. Lv Zheng.

Implemented several changes related to ACPI table support
(Headers/Disassembler/TableCompiler):
NFIT: For ACPI 6.1, updated to add some additional new fields and
constants.
FADT: Updated a warning message and set compliance to ACPI 6.1 (Version
6).
DMAR: Added new constants per the 10/2014 DMAR spec.
IORT: Added new subtable per the 10/2015 IORT spec.
HEST: For ACPI 6.1, added new constants and new subtable.
DBG2: Added new constants per the 12/2015 DBG2 spec.
FPDT: Fixed several incorrect fields, add the FPDT boot record structure.
ACPICA BZ 1249.
ERST/EINJ: Updated disassembler with new "Execute Timings" actions.

Updated header support for the DMAR table to match the current version of
the related spec.

Added extensions to the ASL Concatenate operator to allow any ACPI object
to be passed as an operand. Any object other than Integer/String/Buffer
simply returns a string containing the object type. This extends the
usefulness of the Printf macros. Previously, Concatenate would abort the
control method if a non-data object was encountered.

ACPICA source code: Deployed the C "const" keyword across the source code
where appropriate. ACPICA BZ 732. Joerg Sonnenberger (NetBSD).

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: 137.1K Code, 51.5K Data, 188.6K Total
    Debug Version:     201.0K Code, 82.0K Data, 283.0K Total
  Previous Release:
    Non-Debug Version: 136.2K Code, 51.5K Data, 187.7K Total
    Debug Version:     200.4K Code, 82.0K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Improved the heuristic used to determine the number of
arguments for an externally defined control method (a method in another
table). Although this is an improvement, there is no deterministic way to
"guess" the number of method arguments. Only the ACPI 6.0 External opcode
will completely solve this problem as it is deployed (automatically) in
newer BIOS code.

iASL/Disassembler: Fixed an ordering issue for emitted External() ASL
statements that could cause errors when the disassembled file is
compiled. ACPICA BZ 1243. David Box.

iASL: Fixed a regression caused by the merger of the two versions of the
local strtoul64. Because of a dependency on a global variable, strtoul64
could return an error for integers greater than a 32-bit value. ACPICA BZ
1260.

iASL: Fixed a regression where a fault could occur for an ASL Return
statement if it invokes a control method that is not resolved. ACPICA BZ
1264.

AcpiXtract: Improved input file validation: detection of binary files and
non-acpidump text files.

----------------------------------------
12 February 2016. Summary of changes for version 20160212:

1) ACPICA kernel-resident subsystem:

Implemented full support for the ACPI 6.1 specification (released in
January). This version of the specification is available at:
http://www.uefi.org/specifications

Only a relatively small number of changes were required in ACPICA to
support ACPI 6.1, in these areas:
- New predefined names
- New _HID values
- A new subtable for HEST
- A few other header changes for new values

Ensure \_SB_._INI is executed before any _REG methods are executed. There
appears to be existing BIOS code that relies on this behavior. Lv Zheng.

Reverted a change made in version 20151218 which enabled method
invocations to be targets of various ASL operators (SuperName and Target
grammar elements). While the new behavior is supported by the ACPI
specification, other AML interpreters do not support this behavior and
never will. The ACPI specification will be updated for ACPI 6.2 to remove
this support. Therefore, the change was reverted to the original ACPICA
behavior.

ACPICA now supports the GCC 6 compiler.

Current Release: (Note: build changes increased sizes)
    Non-Debug Version: 136.2K Code, 51.5K Data, 187.7K Total
    Debug Version:     200.4K Code, 82.0K Data, 282.4K Total
Previous Release:
    Non-Debug Version: 102.7K Code, 28.4K Data, 131.1K Total
    Debug Version:     200.4K Code, 81.9K Data, 282.3K Total


2) iASL Compiler/Disassembler and Tools:

Completed full support for the ACPI 6.0 External() AML opcode. The
compiler emits an external AML opcode for each ASL External statement.
This opcode is used by the disassembler to assist with the disassembly of
external control methods by specifying the required number of arguments
for the method. AML interpreters do not use this opcode. To ensure that
interpreters do not even see the opcode, a block of one or more external
opcodes is surrounded by an "If(0)" construct. As this feature becomes
commonly deployed in BIOS code, the ability of disassemblers to correctly
disassemble AML code will be greatly improved. David Box.

iASL: Implemented support for an optional cross-reference output file.
The -lx option will create a the cross-reference file with the suffix
"xrf". Three different types of cross-reference are created in this file:
- List of object references made from within each control method
- Invocation (caller) list for each user-defined control method
- List of references to each non-method object in the namespace

iASL: Method invocations as ASL Target operands are now disallowed and
flagged as errors in preparation for ACPI 6.2 (see the description of the
problem above).

@Import acpica-20160930:

----------------------------------------
30 September 2016. Summary of changes for version 20160930:


1) ACPICA kernel-resident subsystem:

Fixed a regression in the internal AcpiTbFindTable function where a non
AE_OK exception could inadvertently be returned even if the function did
not fail. This problem affects the following operators:
    DataTableRegion
    LoadTable

Fixed a regression in the LoadTable operator where a load to any
namespace location other than the root no longer worked properly.

Increased the maximum loop count value that will result in the
AE_AML_INFINITE_LOOP exception. This is a mechanism that is intended to
prevent infinite loops within the AML interpreter and thus the host OS
kernel. The value is increased from 0xFFFF to 0xFFFFF loops (65,535 to
1,048,575).

Moved the AcpiGbl_MaxLoopIterations configuration variable to the public
acpixf.h file. This allows hosts to easily configure the maximum loop
count at runtime.

Removed an illegal character in the strtoul64.c file. This character
caused errors with some C compilers.

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: 140.4K Code, 58.1K Data, 198.5K Total
    Debug Version:     200.7K Code, 82.1K Data, 282.8K Total
  Previous Release:
    Non-Debug Version: 140.0K Code, 58.1K Data, 198.1K Total
    Debug Version:     200.3K Code, 82.1K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with the conversion of Else{If{ blocks into
the simpler ASL ElseIf keyword. During the conversion, a trailing If
block could be lost and missing from the disassembled output.

iASL: Fixed a missing parser rule for the ObjectType operator. For ASL+,
the missing rule caused a parse error when using the Index operator as an
operand to ObjectType. This construct now compiles properly. Example:
    ObjectType(PKG1[4]).

iASL: Correctly handle unresolved symbols in the hardware map file (-lm
option). Previously, unresolved symbols could cause a protection fault.
Such symbols are now marked as unresolved in the map file.

iASL: Implemented support to allow control method invocations as an
operand to the ASL DeRefOf operator. Example:
    DeRefOf(MTH1(Local0))

Disassembler: Improved support for the ToPLD ASL macro. Detection of a
possible _PLD buffer now includes examination of both the normal buffer
length (16 or 20) as well as the surrounding AML package length.

Disassembler: Fixed a problem with the decoding of complex expressions
within the Divide operator for ASL+. For the case where both the quotient
and remainder targets are specified, the entire statement cannot be
disassembled. Previously, the output incorrectly contained a mix of ASL-
and ASL+ operators. This mixed statement causes a syntax error when
compiled. Example:
    Divide (Add (INT1, 6), 128, RSLT, QUOT)  // was incorrectly
disassembled to:
    Divide (INT1 + 6, 128, RSLT, QUOT)

iASL/Tools: Added support to process AML and non-AML ACPI tables
consistently. For the disassembler and AcpiExec, allow all types of ACPI
tables (AML and data tables). For the iASL -e option, allow only AML
tables (DSDT/SSDT).

----------------------------------------
31 August 2016. Summary of changes for version 20160831:


1) ACPICA kernel-resident subsystem:

Improve support for the so-called "module-level code", which is defined
to be math, logical and control AML opcodes that appear outside of any
control method. This change improves the support by adding more opcodes
that can be executed in the manner. Some other issues have been solved,
and the ASL grammar changes to support such code under all scope
operators (Device, etc.) are complete. Lv Zheng.

UEFI support: these OSL functions have been implemented. This is an
additional step toward supporting the AcpiExec utility natively (with
full hardware access) under UEFI. Marcelo Ferreira.
    AcpiOsReadPciConfiguration
    AcpiOsWritePciConfiguration

Fixed a possible mutex error during control method auto-serialization. Lv
Zheng.

Updated support for the Generic Address Structure by fully implementing
all GAS fields when a 32-bit address is expanded to a 64-bit GAS. Lv
Zheng.

Updated the return value for the internal _OSI method. Instead of
0xFFFFFFFF, the "Ones" value is now returned, which is 0xFFFFFFFFFFFFFFFF
for 64-bit ACPI tables. This fixes an incompatibility with other ACPI
implementations, and will be reflected and clarified in the next version
of the ACPI specification.

Implemented two new table events that can be passed to an ACPICA table
handler. These events are used to indicate a table installation or
uninstallation. These events are used in addition to existed table load
and unload events. Lv Zheng.

Implemented a cleanup for all internal string-to-integer conversions.
Consolidate multiple versions of this functionality and limit possible
bases to either 10 or 16 to simplify the code. Adds a new file,
utstrtoul64.

Cleanup the inclusion order of the various compiler-specific headers.
This simplifies build configuration management. The compiler-specific
headers are now split out from the host-specific headers. 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: 140.1K Code, 58.1K Data, 198.1K Total
    Debug Version:     200.3K Code, 82.1K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

iASL/AcpiExec: Added a command line option to display the build date/time
of the tool (-vd). This can be useful to verify that the correct version
of the tools are being used.

AML Debugger: Implemented a new subcommand ("execute predef") to execute
all predefined control methods and names within the current namespace.
This can be useful for debugging problems with ACPI tables and the ACPI
namespace.

----------------------------------------
29 July 2016. Summary of changes for version 20160729:


1) ACPICA kernel-resident subsystem:

Implemented basic UEFI support for the various ACPICA tools. This
includes:
1) An OSL to implement the various AcpiOs* interfaces on UEFI.
2) Support to obtain the ACPI tables on UEFI.
3) Local implementation of required C library functions not available on
UEFI.
4) A front-end (main) function for the tools for UEFI-related
initialization.

The initial deployment of this support is the AcpiDump utility executing
as an UEFI application via EDK2 (EDKII, "UEFI Firmware Development Kit").
Current environments supported are Linux/Unix. MSVC generation is not
supported at this time. See the generate/efi/README file for build
instructions. Lv Zheng.

Future plans include porting the AcpiExec utility to execute natively on
the platform with I/O and memory access. This will allow viewing/dump of
the platform namespace and native execution of ACPI control methods that
access the actual hardware. To fully implement this support, the OSL
functions below must be implemented with UEFI interfaces. Any community
help in the implementation of these functions would be appreciated:
    AcpiOsReadPort
    AcpiOsWritePort
    AcpiOsReadMemory
    AcpiOsWriteMemory
    AcpiOsReadPciConfiguration
    AcpiOsWritePciConfiguration

Restructured and standardized the C library configuration for ACPICA,
resulting in the various configuration options below. This includes a
global restructuring of the compiler-dependent and platform-dependent
include files. These changes may affect the existing platform-dependent
configuration files on some hosts. Lv Zheng.

The current C library configuration options appear below. For any issues,
it may be helpful to examine the existing compiler-dependent and
platform-dependent files as examples. Lv Zheng.

1) Linux kernel:
    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C
library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
2) Unix/Windows/BSD applications:
    ACPI_USE_STANDARD_HEADERS=y in order to use system-provided C
library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
3) UEFI applications:
    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C
library.
    ACPI_USE_SYSTEM_CLIBRARY=n in order to use ACPICA mini C library.
4) UEFI applications (EDK2/StdLib):
    ACPI_USE_STANDARD_HEADERS=y in order to use EDK2 StdLib C library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order to use EDK2 StdLib C library.


AML interpreter: "module-level code" support. Allows for execution of so-
called "executable" AML code (math/logical operations, etc.) outside of
control methods not just at the module level (top level) but also within
any scope declared outside of a control method - Scope{}, Device{},
Processor{}, PowerResource{}, and ThermalZone{}. Lv Zheng.

Simplified the configuration of the "maximum AML loops" global option by
adding a global public variable, "AcpiGbl_MaxLoopIterations" which can be
modified at runtime.


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: 139.1K Code, 22.9K Data, 162.0K Total
    Debug Version:     199.0K Code, 81.8K Data, 280.8K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Add full support for the RASF ACPI table (RAS Features Table).
Includes disassembler, data table compiler, and header support.

iASL Expand "module-level code" support. Allows for
compilation/disassembly of so-called "executable" AML code (math/logical
operations, etc.) outside of control methods not just at the module level
(top level) but also within any scope declared outside of a control
method - Scope{}, Device{}, Processor{}, PowerResource{}, and
ThermalZone{}.

AcpiDump: Added support for dumping all SSDTs on newer versions of
Windows. These tables are now easily available -- SSDTs are not available
through the registry on older versions.

@----------------------------------------
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.

1.1.1.8
log
@----------------------------------------
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.)

1.1.1.9
log
@Import acpica 2022-10-20

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.
