2014-11-19x86, mce, severity: Extend the the mce_severity mechanism to handle ↵Chen Yucong1-3/+0
UCNA/DEFERRED error Until now, the mce_severity mechanism can only identify the severity of UCNA error as MCE_KEEP_SEVERITY. Meanwhile, it is not able to filter out DEFERRED error for AMD platform. This patch extends the mce_severity mechanism for handling UCNA/DEFERRED error. In order to do this, the patch introduces a new severity level - MCE_UCNA/DEFERRED_SEVERITY. In addition, mce_severity is specific to machine check exception, and it will check MCIP/EIPV/RIPV bits. In order to use mce_severity mechanism in non-exception context, the patch also introduces a new argument (is_excp) for mce_severity. `is_excp' is used to explicitly specify the calling context of mce_severity.

2013-01-23EDAC, MCE, AMD: Remove unneeded exportsBorislav Petkov1-7/+2
Initially, those strings describing different parts of an MCE message were shared with amd64_edac and were therefore exported to modules. However, all except pp_msgs are used only in one place right now so hide them and make them static. No functionality change.

2013-01-23EDAC, MCE, AMD: Add MCE decoding support for Family 16hJacob Shin1-0/+3
Add MCE decoding logic for AMD Family 16h processors. Boris: - drop unneeded uu_msgs export - exit early in cat_mc1_mce and save us an indentation level Signed-off-by: Jacob Shin <jacob.shin@amd.com> Signed-off-by: Borislav Petkov <bp@alien8.de>
2013-01-23EDAC, MCE, AMD: Make MC2 decoding per-familyJacob Shin1-0/+1
Currently only AMD Family 15h processors have special handling for MC2 errors. Since upcoming Family 16h will also need unique handling, let's make MC2 handling part of amd_decoder_ops. Signed-off-by: Jacob Shin <jacob.shin@amd.com> Signed-off-by: Borislav Petkov <bp@alien8.de>

2012-11-28MCE, AMD: Remove functional unit referencesBorislav Petkov1-3/+2
Having the functional unit names in each bank decode is only misleading as this code supports multiple families and there's no guarantee the mapping between FUs and MCE banks will stay the same. And also, knowing the functional unit name doesn't help much since you end up looking at the respective BKDG anyway. So drop all FU references and use the MC bank numbers instead.

2011-03-17amd64_edac: Cleanup NBSH cruftBorislav Petkov1-13/+5
Remove reporting of errors with UC bit set - this is done by the MCE decoding code anyway and this driver deals with DRAM ECC errors only. UC (NB uncorrectable error) doesn't necessarily mean it is a DRAM error. Remove unused macros while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
