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

Optionally copy the entire DSDT to local memory (instead of simply
mapping it.) There are some BIOSs that corrupt or replace the original
DSDT, creating the need for this option. Default is FALSE, do not copy
the DSDT.
This change adds support to detect a DSDT that has been corrupted
and/or replaced from outside the OS (by firmware). This is typically
catastrophic for the system, but has been seen on some machines.
Lin Ming, Bob Moore.
The original implementation only supported reading from a DataTable
region. However, some machines have been seen that actually write to
the ACPI table contained in such a region. This change adds support
for writing to a DataTable region.
Implements some typechecking for values returned by any ACPI
predefiend control methods. Only the direct return of static (unnamed)
values are checked. For example, Return(1). ACPICA BZ 786.
When copying the root table to the new allocation, the length used
was incorrect. The new size was used instead of the current table size,
meaning too much data was copied. Alexey Starikovskiy.
Introduced in commit ae7d6fd(Disassembler: Properly handle externals
with parent-prefix (carat). Fixes a string length allocation calculation.
Lin Ming.
Fixes a problem introduced in version 20100304. An error is incorrectly
generated if a predefined name is declared as a static named object with
a value defined using the keywords "Zero", "One", or "Ones". Lin Ming.
Fixed a problem with the AML Mutex handling function AcpiExReleaseMutex
where the function could fault under the very rare condition when the
interpreter has blocked, the interpreter lock is released, the
interpreter is then reentered via the same thread, and attempts to
acquire a mutex that was previously acquired. FreeBSD report 140979. Lin Ming.
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.
Adds typechecking for static (non-control-method) predefined names.
Migrates compiler to use the common predefined name table (acpredef.h).
Adds a single new file, aslpredef.c. ACPICA BZ 832.
This change will enable debug object output via a global variable,
AcpiGbl_EnableAmlDebugObject. This will help with remote machine
debugging. Also, moved all debug object support code to a new file,
executer/exdebug.c. Entire debug object module can now be configured
out of the ACPICA build if desired. Lin Ming, Bob Moore.
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.
For the predefined methods that return fixed-length packages (or subpackages),
attempt repair for a NULL element. Create an Integer of value 0, a NULL
String, or a zero-length buffer as appropriate. ACPICA BZ 818.
Lin Ming, Bob Moore.
In the case where a specific _HID is requested, do not run _STA until a _HID
match is found. This eliminates potentially dozens of _STA calls during
a search for a particular device/HID.
Fixes ACPICA BZ 828. Lin Ming.
Update all module headers with 2010 copyright. Also includes the
automated cleanup, this is the first time it has been run on the
test suite source, so there are quite a few changes (removal of
extra spaces at the end-of-line, etc.)
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.
