[PATCH v3 0/2] EDAC/amd64: Fix UMC csrow decode and consolidate Family 1Ah setup
From: Vishal Badole
Date: Fri Oct 02 2026 - 07:34:38 EST
Two small amd64_edac fixes/cleanups for AMD Family 1Ah.
Patch 1 is the fix: mask the UMC chip select with 0x3, not 0x7. Only
four chip selects exist, so the old mask could decode an out-of-range
csrow and trip an EDAC warning.
Patch 2 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.
Changes since v2:
- Patch 1 (fix): Simplified the commit message and updated the code
comment.
Changes since v1:
- Patch 1 (fix): Added Fixes: and Cc: stable, and move the fix first.
- Patch 2 (cleanup): Updated the commit message.

v1: https://lore.kernel.org/all/20260925172639.97063-1-Vishal.Badole@xxxxxxx/
