Don't load non-aml tables that are specified on the command line.
Prevents issues, especially with odd tables like the RSDP.
However, allow loading of the FADT. ACPICA BZ 932.
When compiling CreateXxxField operators that access resource descriptor tags,
check that the bit access width matches the actual width of the resource
descriptor field referenced by the tag. ACPICA BZ 930.
These operators were missing from the ACPI specification and thus
did not get pulled into this utility. ACPI 5.0 spec adds them,
and they are added to AcpiHelp.
Conditionally compile the multi-thread support so that threading
libraries will not be linked if not necessary. The only tool
that requires multi-thread support is AcpiExec.
Disable language extensions where possible for maximum portability.
Unfortunately, when MS system includes are used, this option
cannot be used (oswinxf.c)
Runtime option can be used to disable return value repair if this
is causing a problem on a particular machine. Also added an option
to AcpiExec (-dr) to set this disable flag.
Apparently some or all versions of acpidump will occasionally drop
a comment like "Wrong checksum", etc., into the dump file. This
was causing problems for AcpiXtract. ACPICA BZ 905.
Most handlers should be installed before call to AcpiEnableSubsystem.
However, Event handlers and region handlers should be installed
after AcpiInitializeObjects. Override handlers for the "default"
regions should be installed early, however.
ACPICA BZ 848.
The ACPICA headers should appear before any compiler-specific
headers (stdio.h, etc.) so that acenv.h can set any
necessary compiler-specific defines, etc.
Shows example of ACPICA configuration for a minimal namespace
dump utility. Uses table and namespace managers, but no AML
interpreter.
Does not add any functionality over AcpiExec. It is a subset
of AcpiExec. The purpose is to show how to partition and
configure ACPICA.
Contains the complete overhaul of the GPE support code including
removal of _PRW execution, improved handling of wake GPEs, new
external interfaces, and implicit notify support. ACPICA BZ 858,
870,877. Matthew Garrett, Lin Ming, Bob Moore, Rafael Wysocki.
Note: This support is committed as a single patch here because
of multiple patch backporting from Linux and the resulting
interdependency issues.
See the ACPICA reference for full documentation.
Change definition of ACPI_THREAD_ID to always be a UINT64. This simplifies
the code, especially any printf output. UINT64 is the only common data
type for all thread_id types across all operating systems. We now force
the OSL to cast the native thread_id type to UINT64 before returning
the value to ACPICA (via AcpiOsGetThreadId). Lin Ming, Bob Moore.
This function is not OS-dependent and has been replaced by
AcpiHwDerivePciId, which is now in the ACPICA core code.
Local implementations of AcpiOsDerivePciId are no longer
necessary and may be removed. ACPICA BZ 857.
Adds install/remove interfaces so that the host can dynamically
alter the global _OSI table. Also adds support for _OSI handlers.
Additional support: new debugger command (osi), and test support
in the acpiexec utility. Adds new file, utilities/utosi.c.
Lin Ming, Bob Moore. ACPICA bugzilla 836.
After the previous patch that introduced acpi_gpe_wakeup() and
modified the ACPI suspend and wakeup code to use it, the third
argument of acpi_{enable|disable}_gpe() and the GPE wakeup
reference counter are not necessary any more. Remove them and
modify all of the users of acpi_{enable|disable}_gpe()
accordingly. Also drop GPE type constants that aren't used
any more. Rafael J. Wysocki.
-dt option will disable the tracking mechanism, which improves performance
considerably. Also restructured the options into -d (disable) and -e (enable) options.
For all GPEs, including FADT-based and GPE Block Devices, execute
any _PRW methods in the new table, and process any _Lxx/_Exx GPE
methods in the new table. Any runtime GPE that is referred to by
an _Lxx/_Exx method in the new table is immediately enabled.
ACPICA BZ 833. Lin Ming, Bob Moore.
Adds a reference count mechanism to simplify support of shared GPEs that
require multiple device drivers. Several external interfaces have changed.
One external interface has been removed.
Changed:
AcpiEnableGpe
AcpiDisableGpe
AcpiClearGpe
AcpiGetGpeStatus
Removed:
AcpiSetGpeType
New:
AcpiSetGpe

Always use 0x prefix for hex output, use %u for integer output (all
integers are unsigned.)
Affects ACPI_INFO, ACPI_ERROR, ACPI_WARNING, and ACPI_EXCEPTION.
ACPICA BZ 835.
This type was introduced as the code was migrated from ACPI 1.0 (with 32-bit
AML integers) to ACPI 2.0 (with 64-bit integers). It is now obsolete and
this change removes it from the ACPICA code base, replaced by UINT64.
The original typedef has been retained for now for compatibility with
existing device driver code.
Add 2010 copyright to all module headers and signons, including the Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, and all utilities.
Added several new options for the gcc-4 generation, and updated the source
accordingly. This includes some code restructuring to eliminate unreachable
code, elimination of some gotos, elimination of unused return values, and
some additional casting.
This option specifies the value used to initialize buffers used to
simulate operation regions. Default is zero. Useful for debugging
problems that depend on a specific initial value for a region or
field.
This change will repair (by sorting) packages returned by _ALR,
_PSS, and _TSS. Drivers can now assume that the packages are
correctly sorted. Adds one new file, namespace/nsrepair2.c
ACPICA BZ 784. Lin Ming, Bob Moore.
This fixes a problem where the code that attempts to repair/convert an
object of incorrect type is only executed on the first time the
predefined method is called. The mechanism that disables warnings
on subsequent calls was interfering with the repair mechanism.
ACPICA BZ 781.
Handler was never invoked. Now invoked if/when host node is deleted.
Data object was not automatically deleted when host node was deleted.
Interface to handler had an unused parameter, removed it.
ACPICA BZ 778.
Completed a major update for the AcpiGetObjectInfo external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.
Needed by drivers for new ACPi tables.
Internal versions of these functions still use 32-bit max transfers,
in order to minimize disruption and stack use for the standard ACPI
registers (FADT-based).
A 64-bit constant was causing warnings on some compilers since it
does not have a 'LL' suffix. Since 'LL' is not fully portable,
changed the constant to 32-bit since the value is not important to
acpiexec operation. The messy alternative might involve a new
macro to token-past the 'LL' for some compilers.
Added a reader/writer locking mechanism to allow multiple
concurrent namespace walks (readers), but a dynamic table
unload will have exclusive access to the namespace. This fixes
a problem where a table unload could delete the portion of
the namespace that is currently being examined by a walk.
Adds a new file, utlock.c that implements the reader/writer
lock mechanism. ACPICA BZ 749.
Add new globals for the PM1 status registers (A/B), similar to the
way the PM1 enable registers are handled. Instead of overloading the
FADT Event Register blocks. This makes the code clearer and less prone
to error.
Add 2009 copyright to all module headers and signons, including the Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, and all utilities.
Previously, the table override mechanism was implemented for the
DSDT only. Now, any table in the RSDT/XSDT can be replaced by the
host OS. (including the DSDT).
This returns the FADT support to the original behavior, which is to
use default register widths. However, now check each register
definition and report a warning if it differs from the default.
This is a first step to moving away from the default widths, rather
than outright believing the widths in all FADTs for all machines,
considered rather dangerous until more data is obtained.
1) Update the register lengths for the PM1 event blocks. The length
must be divided by two in order to use these to access the status
registers.
2) Add run-time option to use default register lengths to override a
faulty FADT.
3) Add warning message if any of the X64 address structures contain a
length that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.
This function maps an input GPE index to a GPE block device. Also
Added AcpiCurrentGpeCount to track the current number of GPEs that
are being managed by the ACPICA core (both FADT-based GPEs and the GPEs
contained in GPE block devices.)
The current implemenation of _OSI within ACPICA only allows other
control methods to execute _OSI. This change allows the host OS
to execute _OSI via the AcpiEvaluateObject interface. _OSI is a
special method -- it does not exist in the AML code, it is
implemented within ACPICA.
acpi.h now includes only the "public" acpica headers. All other
acpica headers are "private" and should not be included by acpica
users. One new file, accommon.h is used to include the commonly
used private headers for acpica code generation. Future plans are
to move all private headers to a new subdirectory.
Added two initialization examples (within a comment block) that
show how to init ACPI for early table access and for a normal
initialization. Same code will appear in the ACPICA reference
manual.
Use a global pointer instead of using AcpiGetTableByIndex for each
FACS access. This simplifies the code for the Global Lock and the
Firmware Waking Vector(s).
Removed the "$Revision" number that appeared in each module header.
This version number was useful under SourceSafe and CVS, but has no
meaning under git. It is not only incorrect, it could also be
misleading.
Validates predefined ACPI objects that appear in the namespace, at the
time they are evaluated. The argument count and the type of the returned
object are validated. The purpose of this validation is to detect problems
with the BIOS-exposed predefined ACPI objects before the results are
returned to the ACPI-related drivers.
Support for the x2APIC. There are 2 new subtables for the MADT and one new
subtable for the SRAT. Includes disassembler and AcpiSrc support. Data from
the Intel 64 Architecture x2APIC Specification, June 2008.
Correctly handle the case where the EOF happens immediately after
the last table in the input file. Print completion message. Previously,
no message was displayed in this case.
Now calls _CFG method to pass address of table to the AML. Added option
to disable opregion simulation to allow creation of opregion with real
address that was passed to _CFG. All of this allows testing of the Load
and Unload operators from AcpiExec.
Added 2008 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
Designed and implemented new external interfaces to install and remove handlers for ACPI table-related events. Current events that are defined are LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as they are dynamically loaded and unloaded. See AcpiInstallTableHandler and AcpiRemoveTableHandler. (Lin Ming and Bob Moore)
Implemented support to allow Package objects to be passed as method arguments to the AcpiEvaluateObject interface. Previously, this would return an AE_NOT_IMPLEMENTED exception.
Allows AcpiAcquireGlobalLock external interface to be called multiple times by the
same thread. Allows use of AML fields that require the global lock while the running
AML is already holding the global lock.
Added 2007 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
