ACPI: ACPICA 20060331
Implemented header file support for the following
additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
SPMI, TCPA, and WDRT. With this support, all current and
known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.
Implemented support to allow tables that contain ACPI
names with invalid characters to be loaded. Previously,
this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the
behavior of the Microsoft ACPI implementation.
https://bugzilla.novell.com/show_bug.cgi?id=147621
Fixed a couple regressions introduced during the memory
optimization in the 20060317 release. The namespace
node definition required additional reorganization and
an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)
Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object(). (Valery Podrezov,
Fiodor Suietov)
Fixed a memory mapping leak during the deletion of
a SystemMemory operation region where a cached memory
mapping was not deleted. This became a noticeable problem
for operation regions that are defined within frequently
used control methods. (Dana Meyers)
Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,
and another for the miscellaneous ACPI tables that are
consumed by the drivers and other software. The various
FADT definitions were merged into one common section and
three different tables (ACPI 1.0, 1.0+, and 2.0)

ACPI: ACPICA 20060421
Removed a device initialization optimization introduced in
20051216 where the _STA method was not run unless an _INI
was also present for the same device. This optimization
could cause problems because it could allow _INI methods
to be run within a not-present device subtree (If a
not-present device had no _INI, _STA would not be run,
the not-present status would not be discovered, and the
children of the device would be incorrectly traversed.)
Implemented a new _STA optimization where namespace
subtrees that do not contain _INI are identified and
ignored during device initialization. Selectively running
_STA can significantly improve boot time on large machines
(with assistance from Len Brown.)
Implemented support for the device initialization case
where the returned _STA flags indicate a device not-present
but functioning. In this case, _INI is not run, but the
device children are examined for presence, as per the
ACPI specification.
Implemented an additional change to the IndexField support
in order to conform to MS behavior. The value written to
the Index Register is not simply a byte offset, it is a
byte offset in units of the access width of the parent
Index Field. (Fiodor Suietov)
Defined and deployed a new OSL interface,
acpi_os_validate_address(). This interface is called during
the creation of all AML operation regions, and allows
the host OS to exert control over what addresses it will
allow the AML code to access. Operation Regions whose
addresses are disallowed will cause a runtime exception
when they are actually accessed (will not affect or abort
table loading.)
Defined and deployed a new OSL interface,
acpi_os_validate_interface(). This interface allows the host OS
to match the various "optional" interface/behavior strings
for the _OSI predefined control method as appropriate
(with assistance from Bjorn Helgaas.)
Restructured and corrected various problems in the
exception handling code paths within DsCallControlMethod
and DsTerminateControlMethod in dsmethod (with assistance
from Takayoshi Kochi.)
Modified the Linux source converter to ignore quoted string
literals while converting identifiers from mixed to lower
case. This will correct problems with the disassembler
and other areas where such strings must not be modified.
The ACPI_FUNCTION_* macros no longer require quotes around
the function name. This allows the Linux source converter
to convert the names, now that the converter ignores
quoted strings.
