| |
This patchset mainly provides necessary EDAC bits to decode errors occuring on Scalable MCA enabled processors and also updates AMD MCE driver to program the correct MCx_MISC register address for upcoming processors.
Patches 1, 2 and 3 are for upcoming processor.
Patches 4 and 5 are either fixing or adding comments to help in understanding the code and do not introduce any functional changes.
Patch 1: Move MSR definition to mce.h Patch 2: Updates to EDAC driver to decode the new error signatures Patch 3: Fix logic to obtain correct block address Patch 4: Fix deferred error comment Patch 5: Add comments to amd_nb.h to describe threshold_block structure
Note 1: Introduced new patch for moving MCx_CONFIG MSR to mce.h Note 2: The enums, amd_hwids[], and string arrays amd_core_mcablock_names[], amd_df_mcablock_names[] are placed in arch/x86 as there are follow-up patches which use them here.
Changes from V1: (per Boris suggestions) - Simplify error decoding routines - Move headers to mce.h - Rename enumerations and struct members (to be more descriptive) - Drop gerund usage - Remove comments that are spelling out the code
Changes from V2: (per Boris suggestions) - Incorporated all changes as suggested by Boris from here- - http://marc.info/?l=linux-kernel&m=145691594921586&w=2 - http://marc.info/?l=linux-kernel&m=145691606221610&w=2 - http://marc.info/?l=linux-kernel&m=145691610421627&w=2 - No functional change is introduced
Aravind Gopalakrishnan (5): x86/mce: Move MCx_CONFIG MSR definition EDAC, MCE, AMD: Enable error decoding of Scalable MCA errors x86/mce/AMD: Fix logic to obtain block address x86/mce: Clarify comments regarding deferred error x86/mce/AMD: Add comments for easier understanding
