ACPICA: Fixed a couple memory leaks associated with "implicit return"

2009-02-06T22:00:41+00:00

commit d8a0ec914afa1a994d2f6184ac4c6668b5f8068f upstream

Fixed a couple memory leaks associated with "implicit return" objects
when the AML Interpreter slack mode is enabled.

ACPICA: Methods now implicitly return 0 in slack mode

2008-04-22T18:29:29+00:00

Implemented an enhancement to the interpreter "slack mode". In the
absence of an explicit return or an implicitly returned object from
the last executed opcode, a control method will now implicitly
return an integer of value 0 for Microsoft compatibility.

ACPICA: Implemented full argument resolution support for the BankValue argument to BankField

Previously, only constants were supported, now any TermArg may
be used.

ACPICA: Update copyright to 2007.

2007-02-03T02:14:31+00:00

Added 2007 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, iASL compiler,
and the utilities.

ACPICA: Report error if method creates 2 objects with the same name

2007-02-03T02:14:25+00:00

Fixed a regression where an error was no
longer emitted if a control method attempts to create 2
objects of the same name. This previously and now returns
AE_ALREADY_EXISTS. When this exception occurs, it invokes
the mechanism that will dynamically serialize the control
method to possible prevent future errors. (BZ 440)

ACPI: ACPICA 20060623

2006-06-28T07:11:38+00:00

Implemented a new acpi_spinlock type for the OSL lock
interfaces.  This allows the type to be customized to
the host OS for improved efficiency (since a spinlock is
usually a very small object.)

Implemented support for "ignored" bits in the ACPI
registers.  According to the ACPI specification, these
bits should be preserved when writing the registers via
a read/modify/write cycle. There are 3 bits preserved
in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
and PM1_STATUS[11].
http://bugzilla.kernel.org/show_bug.cgi?id=3691

Implemented the initial deployment of new OSL mutex
interfaces.  Since some host operating systems have
separate mutex and semaphore objects, this feature was
requested. The base code now uses mutexes (and the new
mutex interfaces) wherever a binary semaphore was used
previously. However, for the current release, the mutex
interfaces are defined as macros to map them to the
existing semaphore interfaces.

Fixed several problems with the support for the control
method SyncLevel parameter. The SyncLevel now works
according to the ACPI specification and in concert with the
Mutex SyncLevel parameter, since the current SyncLevel is
a property of the executing thread. Mutual exclusion for
control methods is now implemented with a mutex instead
of a semaphore.

Fixed three instances of the use of the C shift operator
in the bitfield support code (exfldio.c) to avoid the use
of a shift value larger than the target data width. The
behavior of C compilers is undefined in this case and can
cause unpredictable results, and therefore the case must
be detected and avoided.  (Fiodor Suietov)

Added an info message whenever an SSDT or OEM table
is loaded dynamically via the Load() or LoadTable()
ASL operators. This should improve debugging capability
since it will show exactly what tables have been loaded
(beyond the tables present in the RSDT/XSDT.)

ACPI: ACPICA 20060526

2006-06-14T06:44:35+00:00

Restructured, flattened, and simplified the internal
interfaces for namespace object evaluation - resulting
in smaller code, less CPU stack use, and fewer
interfaces. (With assistance from Mikhail Kouzmich)

Fixed a problem with the CopyObject operator where the
first parameter was not typed correctly for the parser,
interpreter, compiler, and disassembler. Caused various
errors and unexpected behavior.

Fixed a problem where a ShiftLeft or ShiftRight of
more than 64 bits produced incorrect results with some
C compilers. Since the behavior of C compilers when
the shift value is larger than the datatype width is
apparently not well defined, the interpreter now detects
this condition and simply returns zero as expected in all
such cases. (BZ 395)

Fixed problem reports (Valery Podrezov) integrated: -
Update String-to-Integer conversion to match ACPI 3.0A spec
http://bugzilla.kernel.org/show_bug.cgi?id=5329
Allow interpreter to handle nested method declarations

Fixed problem reports (Fiodor Suietov) integrated: -
acpi_terminate() doesn't free debug memory allocation
list objects (BZ 355) - After Core Subsystem
shutdown, acpi_subsystem_status() returns AE_OK (BZ 356) -
acpi_os_unmap_memory() for RSDP can be invoked inconsistently
(BZ 357) - Resource Manager should return AE_TYPE for
non-device objects (BZ 358) - Incomplete cleanup branch

instead of ACPI_FREE in acpi_rs_set_srs_method_data (BZ 360)
- Incomplete cleanup branch in acpi_ps_parse_aml (BZ 361) -
Incomplete cleanup branch in acpi_ds_delete_walk_state (BZ 362)
- acpi_get_table_header returns AE_NO_ACPI_TABLES until DSDT
