The interpreter now evaluates operands in the order that they appear (both in the
AML and ASL), instead of in reverse order. This previously caused subtle incompatibilities with the MS interpreter as well as being non-intuitive.
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.
Debugger: Enhanced the Statistics/Memory command to emit the total (maximum) memory used during execution, as well as the maximum memory consumed by each of the various object types. (Valery Podrezov)
Support for 16-bit ACPICA has been completely removed since it is no longer necessary and it clutters the code. All 16-bit macros, types, and conditional compiles have been removed, cleaning up and simplifying the code across the entire subsystem. DOS support is no longer needed since the Linux firmware kit is now available.
Optimized the Load operator in the case where the source operand is an operation region. Simply map the operation region memory, instead of performing a bytewise read.
Fixed the Load operator for the case where the source operand is a region field. A buffer object is also allowed as the source operand. BZ 481
Fixed a problem where the Load operator allowed the source operand to be an operation region of any type. It is now restricted to regions of type SystemMemory, as per the ACPI specification. BZ 481
Implemented _CID support for PCI Root Bridge detection. If the _HID does not match the predefined root bridge IDs, the _CID list (if present) is now obtained and also checked for an ID match
Fixed a problem with a possible race condition between threads executing AcpiWalkNamespace and the AML interpreter. This condition was removed by modifying AcpiWalkNamespace to (by default) ignore all temporary namespace entries created during any concurrent control method execution
Completed an AML interpreter performance enhancement for control method execution. Previously a 2-pass parse/execution, control methods are now completely parsed and executed in single pass. This improves overall interpreter performance by ~25%, reduces code size, and reduces CPU stack use.
