2014-11-25EDAC, MCE, AMD: Correct formatting of decoded textBorislav Petkov1-3/+3
Write out MCx_ADDR into the more humanly readable "MCx Error Address" and remove double colon in the output. Cc: Aravind Gopalakrishnan <aravind.gopalakrishnan@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de>

2014-05-08EDAC, MCE, AMD: Remove leftover unused maskBorislav Petkov1-2/+0
295d8cda2689 ("EDAC, MCE, AMD: Drop local coreid reporting") removed the code snippet which used that mask but forgot to drop the mask itself. Do that now. Signed-off-by: Borislav Petkov <bp@suse.de>
2014-02-24MCE, AMD: Fix decoding module loading on unsupported hwBorislav Petkov1-32/+33
We want to still be able to issue some error information on systems for which there is no decoding support (think older distro kernels here, for example). Therefore, we allow module registration but skip the per-family bank-specific decoders and issue the general information only, i.e.: [ 46.822828] [Hardware Error]: Error Status: Uncorrected, software containable error. [ 46.822846] [Hardware Error]: CPU:0 (15:30:0) MC0_STATUS[-|UE|-|-|-|-|-]: 0xa000000000010f0f [ 46.822858] [Hardware Error]: cache level: L3/GEN, mem/io: GEN, mem-tx: GEN, part-proc: GEN (timed out) with the hope that it still contains helpful useful bits.

2013-06-08EDAC, MCE, AMD: Add an MCE signature for new Fam15h modelsAravind Gopalakrishnan1-2/+3
Add a new error signature for Family 15h, models 30h-3fh. Patch has been tested on Fam15h using mce_amd_inj facility and has been verified to work correctly.

2013-01-23EDAC, MCE, AMD: Remove unneeded exportsBorislav Petkov1-11/+6
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. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Borislav Petkov <bp@alien8.de>
2013-01-23EDAC, MCE, AMD: Add MCE decoding support for Family 16hJacob Shin1-17/+78
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 Shin1-27/+29
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: Dump error statusBorislav Petkov1-2/+20
Dump error status after decoding the error which describes the error disposition. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2012-11-28MCE, AMD: Report decoded error type firstBorislav Petkov1-25/+25
Instead of starting with the error details, report the decoded, readable error type first. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2012-11-28MCE, AMD: Dump CPU f/m/s triple with the errorBorislav Petkov1-4/+6
It is very useful to have the family/model/stepping with the reported error so dump it. This saves us asking the bug reporter about it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2012-11-28MCE, AMD: Remove functional unit referencesBorislav Petkov1-94/+92
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. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2012-04-04MCE, AMD: Drop too granulary family model checksBorislav Petkov1-4/+2
MCA details seldom change inbetween the models of a family so don't be too conservative and enable decoding on everything starting from K8 onwards. Minor adjustments can come in later but most importantly, we have some decoding infrastructure in place for upcoming models by default. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2011-12-14x86, mce: Add wrappers for registering on the decode chainBorislav Petkov1-2/+2

2011-10-06EDAC, MCE, AMD: Drop local coreid reportingBorislav Petkov1-19/+1
MCE decoding code is reporting the core which encountered the error unconditionally now so drop this piece. Besides, it reported the coreid in the local processor package which is not that valuable as a datapoint. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-10-06EDAC, MCE, AMD: Print valid addr when reporting an errorBorislav Petkov1-1/+3
The MCi_STATUS bank has a AddrV bit which, when set, denotes that the corresponding MCi_ADDR MSR contains a valid address belonging to the MCE currently being reported. Dump it since it is definitely relevant information. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-10-06EDAC, MCE, AMD: Print CPU number when reporting the errorBorislav Petkov1-2/+2
Currently, correctable ECCs go through mcelog and do not print the scary MCE banner. In that case, however, reporting the core where the CECC happened is important information so dump it along with the decoded string albeit at risk of having a minor redundancy. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Enable driver on F15hBorislav Petkov1-3/+3
Add the PCI device ids required for driver registration. Remove pvt->ctl_name and use the family descriptor directly, instead. Then, bump driver version and fixup its format. Finally, enable DRAM ECC decoding on F15h. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Cleanup NBSH cruftBorislav Petkov1-1/+1
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>
