Subject: [PATCH v3 0/4] x86/mce, EDAC/mce_amd: Support extended MCA_ADDR address on SMCA systems
Date: Fri, 11 Feb 2022 16:34:38 -0600 [thread overview]
Message-ID: <20220211223442.254489-1-Smita.KoralahalliChannabasappa@amd.com> (raw)
This series of patches adds support for extended physical address on newer
AMD processors such as AMD 'Milan'. It also, suggests to cache
MCA_CONFIG[McaX] similar to MCA_CONFIG[McaLsbInStatusSupported] to avoid
reading MCA_CONFIG register each time.
The first patch defines a separate helper function to extract
MCA_ADDR[ErrorAddr].
The second patch adds support for extended ErrorAddr bits in MCA_ADDR.
Third patch, caches MCA_CONFIG[McaX] similar to
MCA_CONFIG[McaLsbInStatusSupported] in the existing mce_bank struct.
Last patch, fixes unnecessary padding in mce_bank struct.
