2005-07-13ACPICA 20050526 from Bob Moore <robert.moore@intel.com>Robert Moore
Implemented support to execute Type 1 and Type 2 AML opcodes appearing at the module level (not within a control method.) 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. Signed-off-by Len Brown <len.brown@intel.com>

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.

2005-07-12ACPICA 20050408 from Bob MooreRobert 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>

2005-06-17When cfq I/O scheduler is selected, get_request() in __make_request() callsKiyoshi Ueda
__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct cfq_queue) of the current process for the device and returns it. If it's not found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that get_request() fails) if no __GFP_WAIT flag. On the other hand, in __make_request(), get_request() is called without __GFP_WAIT flag at the first time. Thus, the get_request() fails when there is no existing queue, typically when it's called for the first I/O request of the process to the device. Though it will be followed by get_request_wait() for general case, __make_request() will just end the I/O with an error (EWOULDBLOCK) when the request was for read-ahead.

2005-06-16[PATCH] sbp2 slab corruption fixAlexandre Oliva
This fixed a problem that showed up in the Fedora development tree a few weeks before the Fedora Core 4 release, initially as slab corruption, later as hard crashes on boot up, when slab debugging was disabled for the release. More details on the history at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424 The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a scsi_id, without explicitly requesting space for it. Since hostdata is declared as a zero-sized array, we don't get any such space by default, so it must be explicitly requested. The patch below implements just that.

2005-06-13[PATCH] Fix PCI BAR size interpretation on 64-bit archesOlof Johansson
On 64-bit machines, PCI_BASE_ADDRESS_MEM_MASK and other mask constants passed to pci_size() are 64-bit (for example ~0x0fUL). However, pci_size does comparisons between the u32 arguments and the mask, which will fail even though any result from pci_size is still just 32-bit. Changing the mask argument to u32 seems the obvious thing to do, since all arithmetic in the function is 32-bit and having a larger mask makes no sense. This triggered on a PPC64 system here where an adapter (VGA, as it happened) had a memory region base of 0xfe000000 and a sz of the same, matching the if (max == maxbase ...) test at the bottom of pci_size but failing the mask comparison. Quite a corner case which I guess explains why we haven't seen it until now.
