2009-09-14EDAC, AMD: carve out decoding of MCi_STATUS ErrorCodeBorislav Petkov2-19/+22
This is the MCE error code from the MCi_STATUS banks, bits [15:0] which describe what type of error was encountered: GART TLB, Memory or Bus error. The semantics of those bits are identical across all MCE banks so decode those separately, irrespectively of MCE type. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14EDAC, AMD: carve out MCi_STATUS decodingBorislav Petkov3-35/+34
The MCi_STATUS registers have most field definitions in common so decode them in the general path. Do not pass ecc_type along and compute it in __amd64_decode_bus_error instead. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14x86, mce: pass mce info to EDAC for decodingBorislav Petkov5-111/+178
Move NB decoder along with required defines to EDAC MCE core. Add registration routines for further decoding of the MCE info in the AMD64 EDAC module. CC: Andi Kleen <andi@firstfloor.org> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2009-09-14EDAC: move MCE error descriptions to EDAC coreBorislav Petkov5-148/+122
This is in preparation of adding AMD-specific MCE decoding functionality to the EDAC core. The error decoding macros originate from the AMD64 EDAC driver albeit in a simplified and cleaned up version here. While at it, add macros to generate the error description strings and use them in the error type decoders directly which removes a bunch of code and makes the decoding functions much more readable. Also, fix strings and shorten macro names. Remove superfluous htlink_msgs. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2009-08-03amd64_edac: fix ECC checkingDoug Thompson1-0/+3
On the good path of BIOS enabled ECC and no override, the value returned is 1 by omission and thus is deemed failing by the probe-function. Allow proper module initialization by clearing the retval explicitly. Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2009-06-26amd64_edac: fix ecc_enable_override handlingBorislav Petkov1-1/+6
amd64_check_ecc_enabled() returns non-zero status when ECC checking/correcting is disabled and this fails further loading of the driver even when 'ecc_enable_override' boot param is used. Fix that by clearing return status in that case. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-06-26amd64_edac: check only ECC bit in amd64_determine_edac_capBorislav Petkov1-3/+2
Checking whether the machine is using ECC enabled DRAM is done through testing the DimmEccEn bit in the DRAM Cfg Low register (F2x[1,0]90). Do that instead of testing all bits from the DimmEccEn upwards. Also, remove mci->edac_cap assignment and use value returned from amd64_determine_edac_cap().
