* ACPICA: Add boot option to disable auto return object repairLv Zheng2014-02-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, there might be bugs caused by unexpected AML which is compliant to the Windows but not compliant to the Linux implementation. There is a predefined validation mechanism implemented in ACPICA to repair the unexpected AML evaluation results that are caused by the unexpected AMLs. For example, BIOS may return misorder _CST result and the repair mechanism can make an ascending order on the returned _CST package object based on the C-state type. This mechanism is quite useful to implement an AML interpreter with better compliance with the real world where Windows is the de-facto standard and BIOS codes are only tested on one platform thus not compliant to the ACPI specification. But if a compliance issue hasn't been figured out yet, it will be difficult for developers to identify if the unexpected evaluation result is caused by this mechanism or by the AML interpreter. For example, _PR0 is expected to be a control method, but BIOS may use Package: "Name(_PR0, Package(1) {P1PR})". This boot option can disable the predefined validation mechanism so that developers can make sure the root cause comes from the parser/executer. This patch adds a new kernel parameter to disable this feature. A build test has been made on a Dell Inspiron mini 1100 (i386 z530) machine when this patch is applied and the corresponding boot test is performed w/ or w/o the new kernel parameter specified.

* ACPICA: Add "Windows 2013" string to _OSI support.Bob Moore2014-02-131-0/+1
| | | | | | | | | | | | | This urgent patch is cherry picked from ACPICA upstream. It is reported that some platforms fail to boot without this new _OSI string. This change adds this string for Windows 8.1 and Server 2012 R2.

* ACPICA: Update the conditions to enable the utility resource dump strings.Lv Zheng2014-02-116-9/+9
| | | | | | | | | | | | | | | | | This patch enables resource dump functions for debugging purpose where ACPI_DEBUG_OUTPUT is enabled. Such functions are useful for developers to track kernel issues when composing debugging patches. They will be optimized out during link stage for normal builds. This patch updates the compilation condition used for the resource dump related string tables to match the compilation environment used for rsdump.c and rsdumpinfo.c. This patch can help to improve the ACPICA release automation. Lv Zheng. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Rafael J.

* ACPICA: Debugger: Add new command to read/write/compare all namespace objects.Bob Moore2014-02-111-0/+2
| | | | | | | | | | | | | This command "test objects" will exercise the entire namespace by writing new values to each data object, and ensuring that the write was successful. The original value is then restored and verified. This patch doesn't affect kernel behavior as the debugger is currently not shipped in the Linux source tree.

* ACPICA: Utilities: Load of local test tables is now optional.Bob Moore2014-02-111-1/+2
| | | | | | | | | | | | | | | | | The utility has the capability to load some various tables to test features of ACPICA. However, there are enough of them that the output of the utility became confusing. With this change, only the required local tables are displayed (RSDP, XSDT, etc.) along with the actual tables loaded via the command line specification. This makes the default output simler and easier to understand. The -el command line option restores the original behavior for testing purposes. This patch doesn't affect kernel behavior as Linux doesn't use ACPICA allocation tracking implementation.

| | | | | | | | | | | | | This change improves the support for physical addresses in printf debug statements and other output on both 32-bit and 64-bit hosts. It consistently outputs the appropriate number of bytes for each host. The %p specifier is unsatisfactory since it does not emit uniform output on all hosts/clib implementations (on some, leading zeros are not supported, leading to difficult-to-read output).

That commit actually caused deadlocks, rather then fixing them. If ext_lock is set to NULL (otherwise videobuf_queue_lock doesn't do anything), then you get this deadlock: The driver's mmap function calls videobuf_mmap_mapper which calls videobuf_queue_lock on q. videobuf_mmap_mapper calls __videobuf_mmap_mapper, __videobuf_mmap_mapper calls videobuf_vm_open and videobuf_vm_open calls videobuf_queue_lock on q (introduced by above patch): deadlocked. This affects drivers using dma-contig and dma-vmalloc. Only dma-sg is not affected since it doesn't call videobuf_vm_open from __videobuf_mmap_mapper. Most drivers these days have a non-NULL ext_lock. Those that still use NULL there are all fairly obscure drivers, which is why this hasn't been seen earlier. Since everything worked perfectly fine for many years I prefer to just revert this patch rather than trying to fix it. videobuf is quite fragile and I rather not touch it too much. Work is (slowly) progressing to move everything over to vb2 or at the very least use non-NULL ext_lock in videobuf.
