[PATCH v2 0/2] x86/mce: Grade new machine errors for AMD MCEs and include messages for panic cases

Posted by Carlos Bilbao 4 years, 2 months ago

This patchset includes grading of new types of machine errors on AMD's MCE
grading logic mce_severity_amd(), which helps the MCE handler determine
what actions to take. If the error is graded as a PANIC, the EDAC driver
will not decode; so we also include new error messages to describe the MCE
and help debugging critical errors.

Changes since v1:
  On patch 1/2, follow a simplified approach for severity.c, that resembles
  the available PPR more closely. This also simplifies patch 2/2, as less 
  panic error messages are added.

Carlos Bilbao (2):
  x86/mce: Extend AMD severity grading function with new types of errors
  x86/mce: Add messages to describe panic machine errors on AMD's MCEs grading
