| * dm thin: fix queue limits stackingMike Snitzer2013-01-311-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thin_io_hints() is blindly copying the queue limits from the thin-pool which can lead to incorrect limits being set. The fix here simply deletes the thin_io_hints() hook which leaves the existing stacking infrastructure to set the limits correctly. When a thin-pool uses an MD device for the data device a thin device from the thin-pool must respect MD's constraints about disallowing a bio from spanning multiple chunks. Otherwise we can see problems. If the raid0 chunksize is 1152K and thin-pool chunksize is 256K I see the following md/raid0 error (with extra debug tracing added to thin_endio) when mkfs.xfs is executed against the thin device: md/raid0:md99: make_request bug: can't convert block across chunks or bigger than 1152k 6688 127 device-mapper: thin: bio sector=2080 err=-5 bi_size=130560 bi_rw=17 bi_vcnt=32 bi_idx=0 This extra DM debugging shows that the failing bio is spanning across the first and second logical 1152K chunk (sector 2080 + 255 takes the bio beyond the first chunk's boundary of sector 2304). So the bio splitting that DM is doing clearly isn't respecting the MD limits. max_hw_sectors_kb is 127 for both the thin-pool and thin device (queue_max_hw_sectors returns 255 so we'll excuse sysfs's lack of precision). So this explains why bi_size is 130560. But the thin device's max_hw_sectors_kb should be 4 (PAGE_SIZE) given that it doesn't have a .merge function (for bio_add_page to consult indirectly via dm_merge_bvec) yet the thin-pool does sit above an MD device that has a compulsory merge_bvec_fn. This scenario is exactly why DM must resort to sending single PAGE_SIZE bios to the underlying layer. Some additional context for this is available in the header for commit 8cbeb67a ("dm: avoid unsupported spanning of md stripe boundaries"). Long story short, the reason a thin device doesn't properly get configured to have a max_hw_sectors_kb of 4 (PAGE_SIZE) is that thin_io_hints() is blindly copying the queue limits from the thin-pool device directly to the thin device's queue limits. Fix this by eliminating thin_io_hints. Doing so is safe because the block layer's queue limits stacking already enables the upper level thin device to inherit the thin-pool device's discard and minimum_io_size and optimal_io_size limits that get set in pool_io_hints. But avoiding the queue limits copy allows the thin and thin-pool limits to be different where it is important, namely max_hw_sectors_kb.

When tracing is enabled, the kernel immediately hangs on boot. This is a result of commit b732d439cb43336cd6d7e804ecb2c81193ef63b0 that changes the kernel/trace/Kconfig file so that is no longer forces FRAME_POINTER when FUNCTION_TRACING is enabled. MIPS frame pointers are generally considered to be useless because they cannot be used to unwind the stack. Unfortunately the MIPS function tracing code has bugs that are masked by the use of frame pointers. This commit fixes the bugs so that MIPS frame pointers don't need to be enabled. The bugs are a result of the odd calling sequence used to call the trace routine. This calling sequence is inserted into every traceable function when the tracing CONFIG option is enabled. This sequence is generated for 32bit MIPS platforms by the compiler via the "-pg" flag. Part of the sequence is "addiu sp,sp,-8" in the delay slot after every call to the trace routine "_mcount" (some legacy thing where 2 arguments used to be pushed on the stack). The _mcount routine is expected to adjust the sp by +8 before returning. So when not disabled, the original jalr and addiu will be there, so _mcount has to adjust sp. The problem is that when tracing is disabled for a function, the "jalr _mcount" instruction is replaced with a nop, but the "addiu sp,sp,-8" is still executed and the stack pointer is left trashed. When frame pointers are enabled the problem is masked because any access to the stack is done through the frame pointer and the stack pointer is restored from the frame pointer when the function returns. This patch writes two nops starting at the address of the "jalr _mcount" instruction whenever tracing is disabled. This means that the "addiu sp,sp.-8" will be converted to a nop along with the "jalr". When disabled, there will be two nops. This is SMP safe because the first time this happens is during ftrace_init() which is before any other processor has been started. Subsequent calls to enable/disable tracing when other CPUs ARE running will still be safe because the enable will only change the first nop to a "jalr" and the disable, while writing 2 nops, will only be changing the "jalr". This patch also stops using stop_machine() to call the tracer enable/disable routines and calls them directly because the routines are SMP safe. When the kernel first boots we have to be able to handle the gcc generated jalr, addui sequence until ftrace_init gets a chance to run and change the sequence. At this point mcount just adjusts the stack and returns. When ftrace_init runs, we convert the jalr/addui to nops. Then whenever tracing is enabled we convert the first nop to a "jalr mcount+8". The mcount+8 entry point skips the stack adjust.

This resulted in macbook pro's no longer finding the rom images, and thus not being able to use the radeon card any more. The solution is to just remove the check for now, and always copy the rom if available.

This leads to users being able to read/write to the file without the variable existing in the firmware. Reading a non-existent variable currently returns -ENOENT, which is confusing because the file obviously *does* exist. Convert EFI_NOT_FOUND into -EIO which is the closest thing to "error while interacting with firmware", and should hopefully indicate to the caller that the variable is in some uninitialised state.
