| * mce, edac: Use an atomic notifier for MCEs decodingBorislav Petkov2009-10-121-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Add an atomic notifier which ensures proper locking when conveying MCE info to EDAC for decoding. The actual notifier call overrides a default, negative priority notifier. Note: make sure we register the default decoder only once since mcheck_init() runs on each CPU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow csrows to properly initialize when the topology only has active channels on 2 and 3. This new check allows proper detection and initialization in this topology. Only checking the first mrt that represented channels 0 and 1 is not sufficient. I also fixed up the related debug information path. I can submit as a 2nd patch if needed.

* | edac: i5400 fix csrow mappingJeff Roberson2009-10-291-61/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i5400 EDAC driver has several bugs with chip-select row computation which most likely lead to bugs in detailed error reporting. Attempts to contact the authors have gone mostly unanswered so I am presenting my diff here. I do not subscribe to lkml and would appreciate being kept in the cc. The most egregious problem was miscalculating the addresses of MTR registers after register 0 by assuming they are 32bit rather than 16. This caused the driver to miss half of the memories. Most motherboards tend to have only 8 dimm slots and not 16, so this may not have been noticed before. Further, the row calculations multiplied the number of dimms several times, ultimately ending up with a maximum row of 32. The chipset only supports 4 dimms in each of 4 channels, so csrow could not be higher than 4 unless you use a row per-rank with dual-rank dimms. I opted to eliminate this behavior as it is confusing to the user and the error reporting works by slot and not rank. This gives a much clearer view of memory by slot and channel in /sys.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the MCE decoding logic into a standalone config option which can be built-in or a module, the first one being the default for MCEs happening early on in the boot process. This, beyond being separated in a cleaner way, also saves RAM by making the decoding logic modular.

While looking at the interaction of decode_mce() with the other MCE code i also noticed a few other things and made the following cleanups/fixes: - Fixed the mce_decode() weak alias - a weak alias is really not good here, it should be a proper callback. A weak alias will be overriden if a piece of code is built into the kernel - not good, obviously. - The patch initializes the callback on AMD family 10h and 11h. - Added the more correct fallback printk of: No support for human readable MCE decoding on this CPU type. Transcribe the message and run it through 'mcelog --ascii' to decode. On CPUs that dont have a decoder. - Made the surrounding code more readable. Note that the callback allows us to have a default fallback - without having to check the CPU versions during the printout itself. When an EDAC module registers itself, it can install the decode-print function. (there's no unregister needed as this is core code.) version -v2 by Borislav Petkov: - add K8 to the set of supported CPUs - always build in edac_mce_amd since we use an early_initcall now - fix checkpatch warnings Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andi Kleen <andi@firstfloor.org> LKML-Reference: <20091001141432.GA11410@aftab> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | amd64_edac: beef up DRAM error injectionBorislav Petkov2009-10-072-10/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask of which bits should be error injected when written to and holds the payload of 16-bit DRAM word when read, respectively. Add /sysfs members to show the DRAM ECC section/word/vector. Fail wrong injection values entered over /sysfs instead of truncating them. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

| | | | | | | | | | | | | | | | | | | Module edac_core.ko uses call_rcu() callbacks in edac_device.c, edac_mc.c and edac_pci.c.

The patch adds a comment about rcu_barrier() and as a precausion calls rcu_barrier(). A maintainer needs to look at removing the wait_for_completion code.
