Subject: [PATCH Intenal 0/2] EDAC/amd64: Add Family 1Ah Model 80h-8Fh support and fix csrow decode
Date: Wed, 23 Sep 2026 16:50:01 +0530	[thread overview]
Message-ID: <20260923112003.3677719-1-Vishal.Badole@amd.com> (raw)

This series adds AMD Family 1Ah Model 80h-8Fh support to the amd64_edac
driver and fixes a UMC csrow decode issue seen on that part.

Patch 1 adds support for Family 1Ah Model 80h-8Fh.

Patch 2 fixes the chip select decode for DRAM ECC errors. The syndrome
field was masked assuming eight chip selects while the controller
implements four, producing an out-of-range csrow and an error reported
against "unknown memory". Mask with the number of chip selects the
controller actually implements.

Tested on a Family 1Ah Model 88h board with injected ECC errors.

  EDAC/amd64: Limit UMC csrow decode to the implemented chip selects
