[PATCH 0/2] EDAC/amd64: Consolidate Family 1Ah setup and fix UMC csrow decode

From: Vishal Badole

Date: Fri Sep 25 2026 - 13:28:07 EST


Two small amd64_edac cleanups/fixes for AMD Family 1Ah.

Patch 1 sets zn_regs_v2 once at the Family 1Ah level instead of in each
model case, so future models cannot miss the v2 register layout. No
functional change.

Patch 2 masks the UMC chip select from MCA_SYND with 0x3 instead of 0x7.
Only four chip selects are ever implemented, so the old mask could decode
an out-of-range csrow and trip an EDAC core warning.

Vishal Badole (2):
EDAC/amd64: Set zn_regs_v2 for all Family 1Ah models
EDAC/amd64: Mask UMC chip select to the four implemented selects
