ACPICA 20050617-0624 from Bob Moore <robert.moore@intel.com> ACPICA 20050617: Moved the object cache operations into the OS interface layer (OSL) to allow the host OS to handle these operations if desired (for example, the Linux OSL will invoke the slab allocator). This support is optional; the compile time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache code in the ACPI CA core. The new OSL interfaces are shown below. See utalloc.c for an example implementation, and acpiosxf.h for the exact interface definitions. Thanks to Alexey Starikovskiy. acpi_os_create_cache acpi_os_delete_cache acpi_os_purge_cache acpi_os_acquire_object acpi_os_release_object Modified the interfaces to acpi_os_acquire_lock and acpi_os_release_lock to return and restore a flags parameter. This fits better with many OS lock models. Note: the current execution state (interrupt handler or not) is no longer passed to these interfaces. If necessary, the OSL must determine this state by itself, a simple and fast operation. Thanks to Alexey Starikovskiy. Fixed a problem in the ACPI table handling where a valid XSDT was assumed present if the revision of the RSDP was 2 or greater. According to the ACPI specification, the XSDT is optional in all cases, and the table manager therefore now checks for both an RSDP >=2 and a valid XSDT pointer. Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain only the RSDT. Fixed an interpreter problem with the Mid() operator in the case of an input string where the resulting output string is of zero length. It now correctly returns a valid, null terminated string object instead of a string object with a null pointer. Fixed a problem with the control method argument handling to allow a store to an Arg object that already contains an object of type Device. The Device object is now correctly overwritten. Previously, an error was returned. ACPICA 20050624: Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for the host-defined cache object. This allows the OSL implementation to define and type this object in any manner desired, simplifying the OSL implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for Linux, and should be defined in the OS-specific header file for other operating systems as required. Changed the interface to AcpiOsAcquireObject to directly return the requested object as the function return (instead of ACPI_STATUS.) This change was made for performance reasons, since this is the purpose of the interface in the first place. acpi_os_acquire_object is now similar to the acpi_os_allocate interface. Thanks to Alexey Starikovskiy. Modified the initialization sequence in acpi_initialize_subsystem to call the OSL interface acpi_osl_initialize first, before any local initialization. This change was required because the global initialization now calls OSL interfaces. Restructured the code base to split some files because of size and/or because the code logically belonged in a separate file. New files are listed below. utilities/utcache.c /* Local cache interfaces */ utilities/utmutex.c /* Local mutex support */ utilities/utstate.c /* State object support */ parser/psloop.c /* Main AML parse loop */ Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA 20050408 from Bob Moore Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>
