19 January 2017. Summary of changes for version 20170119:
This release is available at https://acpica.org/downloads
1) General ACPICA software:
Entire source code base: Added the 2017 copyright to all source code
legal/licensing 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.
2) iASL Compiler/Disassembler and Tools:
iASL: Removed/fixed an inadvertent remark when a method argument
containing a reference is used as a target operand within the method (and
never used as a simple argument), as in the example below. Jeffrey Hugo.
dsdt.asl 1507: Store(0x1, Arg0)
Remark 2146 - ^ Method Argument is never used (Arg0)
All tools: Removed the bit width of the compiler that generated the tool
from the common signon for all user space tools. This proved to be
confusing and unnecessary. This includes similar removal of HARDWARE_NAME
from the generic makefiles (Thomas Petazzoni). Example below.
Old:
ASL+ Optimizing Compiler version 20170119-32
ASL+ Optimizing Compiler version 20170119-64
New:
ASL+ Optimizing Compiler version 20170119
----------------------------------------
22 December 2016. Summary of changes for version 20161222:
1) ACPICA kernel-resident subsystem:
AML Debugger: Implemented a new mechanism to simplify and enhance
debugger integration into all environments, including kernel debuggers
and user-space utilities, as well as remote debug services. This
mechanism essentially consists of new OSL interfaces to support debugger
initialization/termination, as well as wait/notify interfaces to perform
the debugger handshake with the host. Lv Zheng.
New OSL interfaces:
AcpiOsInitializeDebugger (void)
AcpiOsTerminateDebugger (void)
AcpiOsWaitCommandReady (void)
AcpiOsNotifyCommandComplete (void)
New OS services layer:
osgendbg.c -- Example implementation, and used for AcpiExec
Update for Generic Address Space (GAS) support: Although the AccessWidth
and/or BitOffset fields of the GAS are not often used, this change now
fully supports these fields. This affects the internal support for FADT
registers, registers in other ACPI data tables, and the AcpiRead and
AcpiWrite public interfaces. Lv Zheng.
Sleep support: In order to simplify integration of ACPI sleep for the
various host operating systems, a new OSL interface has been introduced.
AcpiOsEnterSleep allows the host to perform any required operations
before the final write to the sleep control register(s) is performed by
ACPICA. Lv Zheng.
New OSL interface:
AcpiOsEnterSleep(SleepState, RegisterAValue, RegisterBValue)
Called from these internal interfaces:
AcpiHwLegacySleep
AcpiHwExtendedSleep
EFI support: Added a very small EFI/ACPICA example application. Provides
a simple demo for EFI integration, as well as assisting with resolution
of issues related to customer ACPICA/EFI integration. Lv Zheng. See:
source/tools/efihello/efihello.c
Local C library: Implemented several new functions to enhance ACPICA
portability, for environments where these clib functions are not
available (such as EFI). Lv Zheng:
putchar
getchar
strpbrk
strtok
memmove
Fixed a regression where occasionally a valid resource descriptor was
incorrectly detected as invalid at runtime, and a
AE_AML_NO_RESOURCE_END_TAG was returned.
Fixed a problem with the recently implemented support that enables
control method invocations as Target operands to many ASL operators.
Warnings of this form: "Needed type [Reference], found [Processor]" were
seen at runtime for some method invocations.
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: 141.5K Code, 58.5K Data, 200.0K Total
Debug Version: 201.7K Code, 82.7K Data, 284.4K Total
Previous Release:
Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
Debug Version: 201.3K Code, 82.7K Data, 284.0K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Enhanced output by adding the capability to detect and
disassemble ASL Switch/Case statements back to the original ASL source
code instead of if/else blocks. David Box.
AcpiHelp: Split a large file into separate files based upon
functionality/purpose. New files are:
ahaml.c
ahasl.c
----------------------------------------
17 November 2016. Summary of changes for version 20161117:
1) ACPICA kernel-resident subsystem:
Table Manager: Fixed a regression introduced in 20160729, "FADT support
cleanup". This was an attempt to remove all references in the source to
the FADT version 2, which never was a legal version number. It was
skipped because it was an early version of 64-bit support that was
eventually abandoned for the current 64-bit support.
Interpreter: Fixed a problem where runtime implicit conversion was
incorrectly disabled for the ASL operators below. This brings the
behavior into compliance with the ACPI specification:
FromBCD
ToBCD
ToDecimalString
ToHexString
ToInteger
ToBuffer
Table Manager: Added a new public interface, AcpiPutTable, used to
release and free an ACPI table returned by AcpiGetTable and related
interfaces. 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: 140.5K Code, 58.5K Data, 198.9K Total
Debug Version: 201.3K Code, 82.7K Data, 284.0K Total
Previous Release:
Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total
Debug Version: 200.7K Code, 82.1K Data, 282.8K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a regression for disassembly of Resource Template.
Detection of templates in the AML stream missed some types of templates.
iASL: Fixed a problem where an Access Size error was returned for the PCC
address space when the AccessSize of the GAS register is greater than a
DWORD. Hoan Tran.
iASL: Implemented several grammar changes for the operators below. These
changes are slated for the next version of the ACPI specification:
RefOf - Disallow method invocation as an operand
CondRefOf - Disallow method invocation as an operand
DerefOf - Disallow operands that use the result from operators
that
do not return a reference (Changed TermArg to
SuperName).
iASL: Control method invocations are now allowed for Target operands, as
per the ACPI specification. Removed error for using a control method
invocation as a Target operand.
Disassembler: Improved detection of Resource Templates, Unicode, and
Strings within Buffer objects. These subtypes do not contain a specific
opcode to indicate the originating ASL code, and they must be detected by
other means within the disassembler.
iASL: Implemented an optimization improvement for 32-bit ACPI tables
(DSDT/SSDT). For the 32-bit case only, compute the optimum integer opcode
only after 64-bit to 32-bit truncation. A truncation warning message is
still emitted, however.
AcpiXtract: Implemented handling for both types of line terminators (LF
or CR/LF) so that it can accept AcpiDump output files from any system.
Peter Wu.
AcpiBin: Added two new options for comparing AML files:
-a: compare and display ALL mismatches
-o: start compare at this offset into the second file
