Make decoding of MCEs happen only on AMD hardware by registering a non-default callback only on CPU families which support it. 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> |
