ACPICA: Allow multiple backslash prefix in namepaths

2009-02-06T21:47:24+00:00

commit d037c5fd7367548191eab2b376a1d08c4ffaf7ff upstream. In a fully qualified namepath, allow multiple backslash prefixes. This can happen because of the use of a double-backslash in strings (since backslash is the escape character) causing confusion.

ACPICA: New: Validation for predefined ACPI methods/objects

2008-10-23T03:14:49+00:00

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.

ACPICA: Fix possible memory leak in acpi_ns_get_external_pathname

2008-10-23T03:14:45+00:00

Fixes a memory leak in the error exit path. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Cleanup for internal Reference Object

2008-10-23T03:14:45+00:00

Fix some sloppiness in the Reference object. No longer use AML opcodes to differentiate the types, introduce new reference Class. Cleanup the debug output code. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Reduce error to warning for incorrect method arg count

2008-10-23T03:14:44+00:00

Previously aborted with error if too few arguments were passed to a control method via the external ACPICA interface. Now issue a warning instead and continue. Handles the case where the method inadvertently declares too many arguments, but does not actually use the extra ones. Applies mainly to the predefined methods. http://bugzilla.kernel.org/show_bug.cgi?id=11032 Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Len Brown

ACPICA: Disallow evaluation of named object types with no value

2008-10-23T03:14:43+00:00

Return AE_TYPE for objects that have no value and therefore evaluation is undefined: Device, Event, Mutex, Region, Thermal, and Scope. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Remove obsolete debug levels (WARN and ERROR)

2008-10-23T03:14:42+00:00

Removed ACPI_DB_WARN and ACPI_DB_ERROR. These debug levels were made obsolete by the ACPI_WARNING and ACPI_ERROR/ACPI_EXCEPTION interfaces. Also added ACPI_DB_EVENTS to correspond with the existing ACPI_LV_EVENTS. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Return method arg count from acpi_get_object_info

2008-10-23T03:14:38+00:00

Also update the debugger so that the correct number of arguments is passed to the method. Prevents a warning message from the debugger. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Andi Kleen Signed-off-by: Len Brown

ACPICA: Add function to dereference returned reference objects

2008-10-23T03:14:37+00:00

Examines the return object from a call to acpi_evaluate_object. Any Index or RefOf references are automatically dereferenced in an attempt to return something useful (these reference types cannot be converted into an external ACPI_OBJECT.)

ACPICA: Add check for invalid handle in acpi_get_object_info

2008-10-23T03:14:35+00:00

Return AE_BAD_PARAMETER if input handle is invalid. http://www.acpica.org/bugzilla/show_bug.cgi?id=474 Signed-off-by: Fiodor Suietov Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Andi Kleen Signed-off-by: Len Brown
