From 6f42ccf2fc50ecee8ea170040627f268430c1648 Mon Sep 17 00:00:00 2001 From: Robert Moore Date: Fri, 13 May 2005 00:00:00 -0400 Subject: ACPICA from Bob Moore Implemented support for PCI Express root bridges -- added support for device PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup. acpi_ev_pci_config_region_setup(). The interpreter now automatically truncates incoming 64-bit constants to 32 bits if currently executing out of a 32-bit ACPI table (Revision < 2). This also affects the iASL compiler constant folding. (Note: as per below, the iASL compiler no longer allows 64-bit constants within 32-bit tables.) Fixed a problem where string and buffer objects with "static" pointers (pointers to initialization data within an ACPI table) were not handled consistently. The internal object copy operation now always copies the data to a newly allocated buffer, regardless of whether the source object is static or not. Fixed a problem with the FromBCD operator where an implicit result conversion was improperly performed while storing the result to the target operand. Since this is an "explicit conversion" operator, the implicit conversion should never be performed on the output. Fixed a problem with the CopyObject operator where a copy to an existing named object did not always completely overwrite the existing object stored at name. Specifically, a buffer-to-buffer copy did not delete the existing buffer. Replaced "interrupt_level" with "interrupt_number" in all GPE interfaces and structs for consistency.

These opcodes are executed exactly once at the time the table is loaded. This type of code was legal up until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in order to provide backwards compatibility with earlier BIOS implementations. This eliminates the "Encountered executable code at module level" warning that was previously generated upon detection of such code. Fixed a problem in the interpreter where an AE_NOT_FOUND exception could inadvertently be generated during the lookup of namespace objects in the second pass parse of ACPI tables and control methods. It appears that this problem could occur during the resolution of forward references to namespace objects. Added the ACPI_MUTEX_DEBUG #ifdef to the acpi_ut_release_mutex function, corresponding to the same the deadlock detection debug code to be compiled out in the normal case, improving mutex performance (and overall subsystem performance) considerably. As suggested by Alexey Starikovskiy. Implemented a handful of miscellaneous fixes for possible memory leaks on error conditions and error handling control paths. These fixes were suggested by FreeBSD and the Coverity Prevent source code analysis tool. Added a check for a null RSDT pointer in acpi_get_firmware_table (tbxfroot.c) to prevent a fault in this error case.

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.

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.

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.
