import new acpica:
----------------------------------------
8 January 2016. Summary of changes for version 20160108:
1) ACPICA kernel-resident subsystem:
Updated all ACPICA copyrights and signons to 2016: Added the 2016
copyright to all source code module headers and utility/tool signons.
This includes the standard Linux dual-license header. This affects
virtually every file in the ACPICA core subsystem, iASL compiler, all
ACPICA utilities, and the ACPICA test suite.
Fixed a regression introduced in version 20151218 concerning the
execution of so-called module-level ASL/AML code. Namespace objects
created under a module-level If() construct were not properly/fully
entered into the namespace and could cause an interpreter fault when
accessed.
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: 102.7K Code, 28.4K Data, 131.1K Total
Debug Version: 200.4K Code, 81.9K Data, 282.4K Total
Previous Release:
Non-Debug Version: 102.6K Code, 28.4K Data, 131.0K Total
Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a problem with the compilation of the GpioIo and GpioInt resource
descriptors. The _PIN field name was incorrectly defined to be an array
of 32-bit values, but the _PIN values are in fact 16 bits each. This
would cause incorrect bit width warnings when using Word (16-bit) fields
to access the descriptors.
----------------------------------------
18 December 2015. Summary of changes for version 20151218:
1) ACPICA kernel-resident subsystem:
Implemented per-AML-table execution of "module-level code" as individual
ACPI tables are loaded into the namespace during ACPICA initialization.
In other words, any module-level code within an AML table is executed
immediately after the table is loaded, instead of batched and executed
after all of the tables have been loaded. This provides compatibility
with other ACPI implementations. ACPICA BZ 1219. Bob Moore, Lv Zheng,
David Box.
To fully support the feature above, the default operation region handlers
for the SystemMemory, SystemIO, and PCI_Config address spaces are now
installed before any ACPI tables are loaded. This enables module-level
code to access these address spaces during the table load and module-
level code execution phase. ACPICA BZ 1220. Bob Moore, Lv Zheng, David
Box.
Implemented several changes to the internal _REG support in conjunction
with the changes above. Also, changes to the AcpiExec/AcpiNames/Examples
utilities for the changes above. Although these tools were changed, host
operating systems that simply use the default handlers for SystemMemory,
SystemIO, and PCI_Config spaces should not require any update. Lv Zheng.
For example, in the code below, DEV1 is conditionally added to the
namespace by the DSDT via module-level code that accesses an operation
region. The SSDT references DEV1 via the Scope operator. DEV1 must be
created immediately after the DSDT is loaded in order for the SSDT to
successfully reference DEV1. Previously, this code would cause an
AE_NOT_EXIST exception during the load of the SSDT. Now, this code is
fully supported by ACPICA.
DefinitionBlock ("", "DSDT", 2, "Intel", "DSDT1", 1)
{
OperationRegion (OPR1, SystemMemory, 0x400, 32)
Field (OPR1, AnyAcc, NoLock, Preserve)
{
FLD1, 1
}
If (FLD1)
{
Device (\DEV1)
{
}
}
}
DefinitionBlock ("", "SSDT", 2, "Intel", "SSDT1", 1)
{
External (\DEV1, DeviceObj)
Scope (\DEV1)
{
}
}
Fixed an AML interpreter problem where control method invocations were
not handled correctly when the invocation was itself a SuperName argument
to another ASL operator. In these cases, the method was not invoked.
ACPICA BZ 1002. Affects the following ASL operators that have a SuperName
argument:
Store
Acquire, Wait
CondRefOf, RefOf
Decrement, Increment
Load, Unload
Notify
Signal, Release, Reset
SizeOf
Implemented automatic String-to-ObjectReference conversion support for
packages returned by predefined names (such as _DEP). A common BIOS error
is to add double quotes around an ObjectReference namepath, which turns
the reference into an unexpected string object. This support detects the
problem and corrects it before the package is returned to the caller that
invoked the method. Lv Zheng.
Implemented extensions to the Concatenate operator. Concatenate now
accepts any type of object, it is not restricted to simply
Integer/String/Buffer. For objects other than these 3 basic data types,
the argument is treated as a string containing the name of the object
type. This expands the utility of Concatenate and the Printf/Fprintf
macros. ACPICA BZ 1222.
Cleaned up the output of the ASL Debug object. The timer() value is now
optional and no longer emitted by default. Also, the basic data types of
Integer/String/Buffer are simply emitted as their values, without a data
type string -- since the data type is obvious from the output. ACPICA BZ
1221.
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: 102.6K Code, 28.4K Data, 131.0K Total
Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
Previous Release:
Non-Debug Version: 102.0K Code, 28.3K Data, 130.3K Total
Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed some issues with the ASL Include() operator. This operator
was incorrectly defined in the iASL parser rules, causing a new scope to
be opened for the code within the include file. This could lead to
several issues, including allowing ASL code that is technically illegal
and not supported by AML interpreters. Note, this does not affect the
related #include preprocessor operator. ACPICA BZ 1212.
iASL/Disassembler: Implemented support for the ASL ElseIf operator. This
operator is essentially an ASL macro since there is no AML opcode
associated with it. The code emitted by the iASL compiler for ElseIf is
an Else opcode followed immediately by an If opcode. The disassembler
will now emit an ElseIf if it finds an Else immediately followed by an
If. This simplifies the decoded ASL, especially for deeply nested
If..Else and large Switch constructs. Thus, the disassembled code more
closely follows the original source ASL. ACPICA BZ 1211. Example:
Old disassembly:
Else
{
If (Arg0 == 0x02)
{
Local0 = 0x05
}
}
New disassembly:
ElseIf (Arg0 == 0x02)
{
Local0 = 0x05
}
AcpiExec: Added support for the new module level code behavior and the
early region installation. This required a small change to the
initialization, since AcpiExec must install its own operation region
handlers.
AcpiExec: Added support to make the debug object timer optional. Default
is timer disabled. This cleans up the debug object output -- the timer
data is rarely used.
AcpiExec: Multiple ACPI tables are now loaded in the order that they
appear on the command line. This can be important when there are
interdependencies/references between the tables.
iASL/Templates. Add support to generate template files with multiple
SSDTs within a single output file. Also added ommand line support to
specify the number of SSDTs (in addition to a single DSDT). ACPICA BZ
1223, 1225.
----------------------------------------
24 November 2015. Summary of changes for version 20151124:
1) ACPICA kernel-resident subsystem:
Fixed a possible regression for a previous update to FADT handling. The
FADT no longer has a fixed table ID, causing some issues with code that
was hardwired to a specific ID. Lv Zheng.
Fixed a problem where the method auto-serialization could interfere with
the current SyncLevel. This change makes the auto-serialization support
transparent to the SyncLevel support and management.
Removed support for the _SUB predefined name in AcpiGetObjectInfo. This
interface is intended for early access to the namespace during the
initial namespace device discovery walk. The _SUB method has been seen to
access operation regions in some cases, causing errors because the
operation regions are not fully initialized.
AML Debugger: Fixed some issues with the terminate/quit/exit commands
that can cause faults. Lv Zheng.
AML Debugger: Add thread ID support so that single-step mode only applies
to the AML Debugger thread. This prevents runtime errors within some
kernels. Lv Zheng.
Eliminated extraneous warnings from AcpiGetSleepTypeData. Since the _Sx
methods that are invoked by this interface are optional, removed warnings
emitted for the case where one or more of these methods do not exist.
ACPICA BZ 1208, original change by Prarit Bhargava.
Made a major pass through the entire ACPICA source code base to
standardize formatting that has diverged a bit over time. There are no
functional changes, but this will of course cause quite a few code
differences from the previous ACPICA release.
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: 102.0K Code, 28.3K Data, 130.3K Total
Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
Previous Release:
Non-Debug Version: 101.7K Code, 27.9K Data, 129.6K Total
Debug Version: 199.3K Code, 81.4K Data, 280.7K Total
2) iASL Compiler/Disassembler and Tools:
iASL/acpiexec/acpixtract/disassembler: Added support to allow multiple
definition blocks within a single ASL file and the resulting AML file.
Support for this type of file was also added to the various tools that
use binary AML files: acpiexec, acpixtract, and the AML disassembler. The
example code below shows two definition blocks within the same file:
DefinitionBlock ("dsdt.aml", "DSDT", 2, "Intel", "Template",
0x12345678)
{
}
DefinitionBlock ("", "SSDT", 2, "Intel", "Template", 0xABCDEF01)
{
}
iASL: Enhanced typechecking for the Name() operator. All expressions for
the value of the named object must be reduced/folded to a single constant
at compile time, as per the ACPI specification (the AML definition of
Name()).
iASL: Fixed some code indentation issues for the -ic and -ia options (C
and assembly headers). Now all emitted code correctly begins in column 1.
iASL: Added an error message for an attempt to open a Scope() on an
object defined in an SSDT. The DSDT is always loaded into the namespace
first, so any attempt to open a Scope on an SSDT object will fail at
runtime.
----------------------------------------
30 September 2015. Summary of changes for version 20150930:
1) ACPICA kernel-resident subsystem:
Debugger: Implemented several changes and bug fixes to assist support for
the in-kernel version of the AML debugger. Lv Zheng.
- Fix the "predefined" command for in-kernel debugger.
- Do not enter debug command loop for the help and version commands.
- Disallow "execute" command during execution/single-step of a method.
Interpreter: Updated runtime typechecking for all operators that have
target operands. The operand is resolved and validated that it is legal.
For example, the target cannot be a non-data object such as a Device,
Mutex, ThermalZone, etc., as per the ACPI specification.
Debugger: Fixed the double-mutex user I/O handshake to work when local
deadlock detection is enabled.
Debugger: limited display of method locals and arguments (LocalX and
ArgX) to only those that have actually been initialized. This prevents
lines of extraneous output.
Updated the definition of the NFIT table to correct the bit polarity of
one flag: ACPI_NFIT_MEM_ARMED --> ACPI_NFIT_MEM_NOT_ARMED
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: 101.7K Code, 27.9K Data, 129.6K Total
Debug Version: 199.3K Code, 81.4K Data, 280.7K Total
Previous Release:
Non-Debug Version: 101.3K Code, 27.7K Data, 129.0K Total
Debug Version: 198.6K Code, 80.9K Data, 279.5K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Improved the compile-time typechecking for operands of many of the
ASL operators:
-- Added an option to disable compiler operand/operator typechecking (-
ot).
-- For the following operators, the TermArg operands are now validated
when possible to be Integer data objects: BankField, OperationRegion,
DataTableRegion, Buffer, and Package.
-- Store (Source, Target): Both the source and target operands are
resolved and checked that the operands are both legal. For example,
neither operand can be a non-data object such as a Device, Mutex,
ThermalZone, etc. Note, as per the ACPI specification, the CopyObject
operator can be used to store an object to any type of target object.
-- Store (Source, Target): If the source is a Package object, the target
must be a Package object, LocalX, ArgX, or Debug. Likewise, if the target
is a Package, the source must also be a Package.
-- Store (Source, Target): A warning is issued if the source and target
resolve to the identical named object.
-- Store (Source, <method invocation>): An error is generated for the
target method invocation, as this construct is not supported by the AML
interpreter.
-- For all ASL math and logic operators, the target operand must be a
data object (Integer, String, Buffer, LocalX, ArgX, or Debug). This
includes the function return value also.
-- External declarations are also included in the typechecking where
possible. External objects defined using the UnknownObj keyword cannot be
typechecked, however.
iASL and Disassembler: Added symbolic (ASL+) support for the ASL Index
operator:
- Legacy code: Index(PKG1, 3)
- New ASL+ code: PKG1[3]
This completes the ACPI 6.0 ASL+ support as it was the only operator not
supported.
iASL: Fixed the file suffix for the preprocessor output file (.i). Two
spaces were inadvertently appended to the filename, causing file access
and deletion problems on some systems.
ASL Test Suite (ASLTS): Updated the master makefile to generate all
possible compiler output files when building the test suite -- thus
exercising these features of the compiler. These files are automatically
deleted when the test suite exits.
----------------------------------------
18 August 2015. Summary of changes for version 20150818:
1) ACPICA kernel-resident subsystem:
Fix a regression for AcpiGetTableByIndex interface causing it to fail. Lv
Zheng. ACPICA BZ 1186.
Completed development to ensure that the ACPICA Disassembler and Debugger
are fully standalone components of ACPICA. Removed cross-component
dependences. Lv Zheng.
The max-number-of-AML-loops is now runtime configurable (previously was
compile-time only). This is essentially a loop timeout to force-abort
infinite AML loops. ACPCIA BZ 1192.
Debugger: Cleanup output to dump ACPI names and namepaths without any
trailing underscores. Lv Zheng. ACPICA BZ 1135.
Removed unnecessary conditional compilations across the Debugger and
Disassembler components where entire modules could be left uncompiled.
The aapits test is deprecated and has been removed from the ACPICA git
tree. The test has never been completed and has not been maintained, thus
becoming rather useless. ACPICA BZ 1015, 794.
A batch of small changes to close bugzilla and other reports:
- Remove duplicate code for _PLD processing. ACPICA BZ 1176.
- Correctly cleanup after a ACPI table load failure. ACPICA BZ 1185.
- iASL: Support POSIX yacc again in makefile. Jung-uk Kim.
- ACPI table support: general cleanup and simplification. Lv Zheng, Bob
Moore.
- ACPI table support: fix for a buffer read overrun in AcpiTbFindTable.
ACPICA BZ 1184.
- Enhance parameter validation for DataTableRegion and LoadTable ASL/AML
operators.
- Debugger: Split debugger initialization/termination interfaces. Lv
Zheng.
- AcpiExec: Emit OemTableId for SSDTs during the load phase for table
identification.
- AcpiExec: Add debug message during _REG method phase during table
load/init.
- AcpiNames: Fix a regression where some output was missing and no longer
emitted.
- Debugger: General cleanup and simplification. Lv Zheng.
- Disassembler: Cleanup use of several global option variables. 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: 101.3K Code, 27.7K Data, 129.0K Total
Debug Version: 198.6K Code, 80.9K Data, 279.5K Total
Previous Release:
Non-Debug Version: 100.9K Code, 24.5K Data, 125.4K Total
Debug Version: 197.8K Code, 81.5K Data, 279.3K Total
2) iASL Compiler/Disassembler and Tools:
AcpiExec: Fixed a problem where any more than 32 ACPI tables in the XSDT
were not handled properly and caused load errors. Now, properly invoke
and use the ACPICA auto-reallocate mechanism for ACPI table data
structures. ACPICA BZ 1188
AcpiNames: Add command-line wildcard support for ACPI table files. ACPICA
BZ 1190.
AcpiExec and AcpiNames: Add -l option to load ACPI tables only. For
AcpiExec, this means that no control methods (like _REG/_INI/_STA) are
executed during initialization. ACPICA BZ 1187, 1189.
iASL/Disassembler: Implemented a prototype "listing" mode that emits AML
that corresponds to each disassembled ASL statement, to simplify
debugging. ACPICA BZ 1191.
Debugger: Add option to the "objects" command to display a summary of the
current namespace objects (Object type and count). This is displayed if
the command is entered with no arguments.
AcpiNames: Add -x option to specify debug level, similar to AcpiExec.

----------------------------------------
+8 January 2016. Summary of changes for version 20160108:
+
+1) ACPICA kernel-resident subsystem:
+
+Updated all ACPICA copyrights and signons to 2016: Added the 2016
+copyright to all source code module headers and utility/tool signons.
+This includes the standard Linux dual-license header. This affects
+virtually every file in the ACPICA core subsystem, iASL compiler, all
+ACPICA utilities, and the ACPICA test suite.
+
+Fixed a regression introduced in version 20151218 concerning the
+execution of so-called module-level ASL/AML code. Namespace objects
+created under a module-level If() construct were not properly/fully
+entered into the namespace and could cause an interpreter fault when
+accessed.
+
+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: 102.7K Code, 28.4K Data, 131.1K Total
+ Debug Version: 200.4K Code, 81.9K Data, 282.4K Total
+ Previous Release:
+ Non-Debug Version: 102.6K Code, 28.4K Data, 131.0K Total
+ Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed a problem with the compilation of the GpioIo and GpioInt resource
+descriptors. The _PIN field name was incorrectly defined to be an array
+of 32-bit values, but the _PIN values are in fact 16 bits each. This
+would cause incorrect bit width warnings when using Word (16-bit) fields
+to access the descriptors.
+
+
+----------------------------------------
+18 December 2015. Summary of changes for version 20151218:
+
+1) ACPICA kernel-resident subsystem:
+
+Implemented per-AML-table execution of "module-level code" as individual
+ACPI tables are loaded into the namespace during ACPICA initialization.
+In other words, any module-level code within an AML table is executed
+immediately after the table is loaded, instead of batched and executed
+after all of the tables have been loaded. This provides compatibility
+with other ACPI implementations. ACPICA BZ 1219. Bob Moore, Lv Zheng,
+David Box.
+
+To fully support the feature above, the default operation region handlers
+for the SystemMemory, SystemIO, and PCI_Config address spaces are now
+installed before any ACPI tables are loaded. This enables module-level
+code to access these address spaces during the table load and module-
+level code execution phase. ACPICA BZ 1220. Bob Moore, Lv Zheng, David
+Box.
+
+Implemented several changes to the internal _REG support in conjunction
+with the changes above. Also, changes to the AcpiExec/AcpiNames/Examples
+utilities for the changes above. Although these tools were changed, host
+operating systems that simply use the default handlers for SystemMemory,
+SystemIO, and PCI_Config spaces should not require any update. Lv Zheng.
+
+For example, in the code below, DEV1 is conditionally added to the
+namespace by the DSDT via module-level code that accesses an operation
+region. The SSDT references DEV1 via the Scope operator. DEV1 must be
+created immediately after the DSDT is loaded in order for the SSDT to
+successfully reference DEV1. Previously, this code would cause an
+AE_NOT_EXIST exception during the load of the SSDT. Now, this code is
+fully supported by ACPICA.
+
+ DefinitionBlock ("", "DSDT", 2, "Intel", "DSDT1", 1)
+ {
+ OperationRegion (OPR1, SystemMemory, 0x400, 32)
+ Field (OPR1, AnyAcc, NoLock, Preserve)
+ {
+ FLD1, 1
+ }
+ If (FLD1)
+ {
+ Device (\DEV1)
+ {
+ }
+ }
+ }
+ DefinitionBlock ("", "SSDT", 2, "Intel", "SSDT1", 1)
+ {
+ External (\DEV1, DeviceObj)
+ Scope (\DEV1)
+ {
+ }
+ }
+
+Fixed an AML interpreter problem where control method invocations were
+not handled correctly when the invocation was itself a SuperName argument
+to another ASL operator. In these cases, the method was not invoked.
+ACPICA BZ 1002. Affects the following ASL operators that have a SuperName
+argument:
+ Store
+ Acquire, Wait
+ CondRefOf, RefOf
+ Decrement, Increment
+ Load, Unload
+ Notify
+ Signal, Release, Reset
+ SizeOf
+
+Implemented automatic String-to-ObjectReference conversion support for
+packages returned by predefined names (such as _DEP). A common BIOS error
+is to add double quotes around an ObjectReference namepath, which turns
+the reference into an unexpected string object. This support detects the
+problem and corrects it before the package is returned to the caller that
+invoked the method. Lv Zheng.
+
+Implemented extensions to the Concatenate operator. Concatenate now
+accepts any type of object, it is not restricted to simply
+Integer/String/Buffer. For objects other than these 3 basic data types,
+the argument is treated as a string containing the name of the object
+type. This expands the utility of Concatenate and the Printf/Fprintf
+macros. ACPICA BZ 1222.
+
+Cleaned up the output of the ASL Debug object. The timer() value is now
+optional and no longer emitted by default. Also, the basic data types of
+Integer/String/Buffer are simply emitted as their values, without a data
+type string -- since the data type is obvious from the output. ACPICA BZ
+1221.
+
+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: 102.6K Code, 28.4K Data, 131.0K Total
+ Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
+ Previous Release:
+ Non-Debug Version: 102.0K Code, 28.3K Data, 130.3K Total
+ Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed some issues with the ASL Include() operator. This operator
+was incorrectly defined in the iASL parser rules, causing a new scope to
+be opened for the code within the include file. This could lead to
+several issues, including allowing ASL code that is technically illegal
+and not supported by AML interpreters. Note, this does not affect the
+related #include preprocessor operator. ACPICA BZ 1212.
+
+iASL/Disassembler: Implemented support for the ASL ElseIf operator. This
+operator is essentially an ASL macro since there is no AML opcode
+associated with it. The code emitted by the iASL compiler for ElseIf is
+an Else opcode followed immediately by an If opcode. The disassembler
+will now emit an ElseIf if it finds an Else immediately followed by an
+If. This simplifies the decoded ASL, especially for deeply nested
+If..Else and large Switch constructs. Thus, the disassembled code more
+closely follows the original source ASL. ACPICA BZ 1211. Example:
+
+ Old disassembly:
+ Else
+ {
+ If (Arg0 == 0x02)
+ {
+ Local0 = 0x05
+ }
+ }
+
+ New disassembly:
+ ElseIf (Arg0 == 0x02)
+ {
+ Local0 = 0x05
+ }
+
+AcpiExec: Added support for the new module level code behavior and the
+early region installation. This required a small change to the
+initialization, since AcpiExec must install its own operation region
+handlers.
+
+AcpiExec: Added support to make the debug object timer optional. Default
+is timer disabled. This cleans up the debug object output -- the timer
+data is rarely used.
+
+AcpiExec: Multiple ACPI tables are now loaded in the order that they
+appear on the command line. This can be important when there are
+interdependencies/references between the tables.
+
+iASL/Templates. Add support to generate template files with multiple
+SSDTs within a single output file. Also added ommand line support to
+specify the number of SSDTs (in addition to a single DSDT). ACPICA BZ
+1223, 1225.
+
+
+----------------------------------------
+24 November 2015. Summary of changes for version 20151124:
+
+1) ACPICA kernel-resident subsystem:
+
+Fixed a possible regression for a previous update to FADT handling. The
+FADT no longer has a fixed table ID, causing some issues with code that
+was hardwired to a specific ID. Lv Zheng.
+
+Fixed a problem where the method auto-serialization could interfere with
+the current SyncLevel. This change makes the auto-serialization support
+transparent to the SyncLevel support and management.
+
+Removed support for the _SUB predefined name in AcpiGetObjectInfo. This
+interface is intended for early access to the namespace during the
+initial namespace device discovery walk. The _SUB method has been seen to
+access operation regions in some cases, causing errors because the
+operation regions are not fully initialized.
+
+AML Debugger: Fixed some issues with the terminate/quit/exit commands
+that can cause faults. Lv Zheng.
+
+AML Debugger: Add thread ID support so that single-step mode only applies
+to the AML Debugger thread. This prevents runtime errors within some
+kernels. Lv Zheng.
+
+Eliminated extraneous warnings from AcpiGetSleepTypeData. Since the _Sx
+methods that are invoked by this interface are optional, removed warnings
+emitted for the case where one or more of these methods do not exist.
+ACPICA BZ 1208, original change by Prarit Bhargava.
+
+Made a major pass through the entire ACPICA source code base to
+standardize formatting that has diverged a bit over time. There are no
+functional changes, but this will of course cause quite a few code
+differences from the previous ACPICA release.
+
+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: 102.0K Code, 28.3K Data, 130.3K Total
+ Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
+ Previous Release:
+ Non-Debug Version: 101.7K Code, 27.9K Data, 129.6K Total
+ Debug Version: 199.3K Code, 81.4K Data, 280.7K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL/acpiexec/acpixtract/disassembler: Added support to allow multiple
+definition blocks within a single ASL file and the resulting AML file.
+Support for this type of file was also added to the various tools that
+use binary AML files: acpiexec, acpixtract, and the AML disassembler. The
+example code below shows two definition blocks within the same file:
+
+ DefinitionBlock ("dsdt.aml", "DSDT", 2, "Intel", "Template",
+0x12345678)
+ {
+ }
+ DefinitionBlock ("", "SSDT", 2, "Intel", "Template", 0xABCDEF01)
+ {
+ }
+
+iASL: Enhanced typechecking for the Name() operator. All expressions for
+the value of the named object must be reduced/folded to a single constant
+at compile time, as per the ACPI specification (the AML definition of
+Name()).
+
+iASL: Fixed some code indentation issues for the -ic and -ia options (C
+and assembly headers). Now all emitted code correctly begins in column 1.
+
+iASL: Added an error message for an attempt to open a Scope() on an
+object defined in an SSDT. The DSDT is always loaded into the namespace
+first, so any attempt to open a Scope on an SSDT object will fail at
+runtime.

+----------------------------------------
+30 September 2015. Summary of changes for version 20150930:
+
+1) ACPICA kernel-resident subsystem:
+
+Debugger: Implemented several changes and bug fixes to assist support for
+the in-kernel version of the AML debugger. Lv Zheng.
+- Fix the "predefined" command for in-kernel debugger.
+- Do not enter debug command loop for the help and version commands.
+- Disallow "execute" command during execution/single-step of a method.
+
+Interpreter: Updated runtime typechecking for all operators that have
+target operands. The operand is resolved and validated that it is legal.
+For example, the target cannot be a non-data object such as a Device,
+Mutex, ThermalZone, etc., as per the ACPI specification.
+
+Debugger: Fixed the double-mutex user I/O handshake to work when local
+deadlock detection is enabled.
+
+Debugger: limited display of method locals and arguments (LocalX and
+ArgX) to only those that have actually been initialized. This prevents
+lines of extraneous output.
