* [PATCH] `unaligned access' in acpi get_root_bridge_busnr()Peter Chubb2005-10-191-4/+4
| | | | | | | | | | | | In drivers/acpi/glue.c the address of an integer is cast to the address of an unsigned long. This breaks on systems where a long is larger than an int --- for a start the int can be misaligned; for a second the assignment through the pointer will overwrite part of the next variable.

| | | | | | | | | | | | Remove S4BIOS support. It is pretty useless, and only ever worked for _me_ once. (I do not think anyone else ever tried it). It was in feature-removal for a long time, and it should have been removed before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a problem with the internal Owner ID allocation and deallocation mechanisms for control method execution and recursive method invocation. This should eliminate the OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages seen on some systems. Recursive method invocation depth is currently limited to 255. (Alexey Starikovskiy) http://bugzilla.kernel.org/show_bug.cgi?id=4892 Completely eliminated all vestiges of support for the "module-level executable code" until this support is fully implemented and debugged. This should eliminate the NO_RETURN_VALUE exceptions seen during table load on some systems that invoke this support. http://bugzilla.kernel.org/show_bug.cgi?id=5162 Fixed a problem within the resource manager code where the transaction flags for a 64-bit address descriptor were handled incorrectly in the type-specific flag byte. Consolidated duplicate code within the address descriptor resource manager code, reducing overall subsystem code size.

| | | | | | | | | | | | | | Implemented a full bytewise compare to determine if a table load request is attempting to load a duplicate table. The compare is performed if the table signatures and table lengths match. This will allow different tables with the same OEM Table ID and revision to be loaded. Although the BIOS is technically violating the ACPI spec when this happens -- it does happen -- so Linux must handle it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Andi Kleen suggested it was unconventional for us to "default m" on ACPI modules -- even though they are expected to be deployed as modules.

Apparently there exists BIOS code that repeatedly attempts to load the same SSDT upon certain events. Thanks to Venkatesh Pallipadi. Restructured the main interface to the AML parser in order to correctly handle all exceptional conditions. This will prevent leakage of the OwnerId resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some machines. Thanks to Alexey Starikovskiy. Support for "module level code" has been disabled in this version due to a number of issues that have appeared on various machines. The support can be enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem compilation. When the issues are fully resolved, the code will be enabled by default again. Modified the internal functions for debug print support to define the FunctionName parameter as a (const char *) for compatibility with compiler built-in macros such as __FUNCTION__, etc. Linted the entire ACPICA source tree for both 32-bit and 64-bit.

Previously, a debug structure was declared in every function that used the debug macros. This structure has been removed in favor of declaring the individual elements as parameters to the debug functions. This reduces the cumulative stack use during nested execution of ACPI function calls at the cost of a small increase in the code size of the debug version of the subsystem. With assistance from Alexey Starikovskiy and Len Brown. Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent headers to define a macro that will return the current function name at runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the compiler-dependent header, the function name is saved on the CPU stack (one pointer per function.) This mechanism is used because apparently there exists no standard ANSI-C defined macro that that returns the function name. Alexey Starikovskiy redesigned and reimplemented the "Owner ID" mechanism used to track namespace objects created/deleted by ACPI tables and control method execution. A bitmap is now used to allocate and free the IDs, thus solving the wraparound problem present in the previous implementation. The size of the namespace node descriptor was reduced by 2 bytes as a result. Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield flag definitions within the headers for the predefined ACPI tables. These have been replaced by UINT8_BIT in order to increase the code portability of the subsystem. If the use of UINT8 remains a problem, we may be forced to eliminate bitfields entirely because of a lack of portability. Alexey Starikovksiy enhanced the performance of acpi_ut_update_object_reference. This is a frequently used function and this improvement increases the performance of the entire subsystem. Alexey Starikovskiy fixed several possible memory leaks and the inverse - premature object deletion. Signed-off-by: Len Brown <len.brown@intel.com>
