Name : acpica-tools
Product : Fedora 22
Version : 20160422
Release : 1.fc22
URL : https://www.acpica.org/
Summary : ACPICA tools for the development and debug of ACPI tables
Description :
The ACPI Component Architecture (ACPICA) project provides an OS-independent
reference implementation of the Advanced Configuration and Power Interface
Specification (ACPI). ACPICA code contains those portions of ACPI meant to
be directly integrated into the host OS as a kernel-resident subsystem, and
a small set of tools to assist in developing and debugging ACPI tables.
This package contains only the user-space tools needed for ACPI table
development, not the kernel implementation of ACPI. The following commands
are installed:
-- iasl: compiles ASL (ACPI Source Language) into AML (ACPI Machine
Language), suitable for inclusion as a DSDT in system firmware.
It also can disassemble AML, for debugging purposes.
-- acpibin: performs basic operations on binary AML files (e.g.,
comparison, data extraction)
-- acpidump: write out the current contents of ACPI tables
-- acpiexec: simulate AML execution in order to debug method definitions
-- acpihelp: display help messages describing ASL keywords and op-codes
-- acpinames: display complete ACPI name space from input AML
-- acpisrc: manipulate the ACPICA source tree and format source files
for specific environments
-- acpixtract: extract binary ACPI tables from acpidump output (see
also the pmtools package)
This version of the tools is being released under GPLv2 license.

Update Information:
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.
