From: Muralidhara M K <muralidhara.mk@amd.com>
This patchset adds support for MI200 heterogeneous address translation support and MI300A address translation support, Few fixups on HBM3 memory address maps to convert on-die(MCA decoded) address to Normalized address.
The patch set depends on the Yazen's patches submitted "AMD Address Translation Library" https://lore.kernel.org/r/20231005173526.42831-1-yazen.ghannam@amd.com
The patchset does the following
Patch 1: MI200 heterogeneous address translation support.
Patch 2: MI300 heterogeneous address translation support.
Patch 3: Convert HBM3 MCA Decoded address to Normalized address.
Patch 4: lookup table to get the correct cs instance id for HBM3.
Patch 5: Convert physical cs id to logical cs id by static lookup table.
Patch 6: Identify all 8 column system physical addresses from each HBM3 row and retire all column addresses when the error is injected to avoid future errors.
Muralidhara M K (6): RAS: Add Address Translation support for MI200 RAS: Add Address Translation support for MI300 RAS: Add MCA Error address conversion for UMC RAS: Add static lookup table to get CS physical ID RAS: Add fixed Physical to logical CS ID mapping table RAS: EDAC/amd64: Retire all system physical address from HBM3 row
