From fdce765a13384cf411d456472d396d8db2b3114f Mon Sep 17 00:00:00 2001 From: Yazen Ghannam Date: Fri, 27 Jan 2023 17:03:58 +0000 Subject: EDAC/amd64: Don't set up EDAC PCI control on Family 17h+ EDAC PCI control is used to detect/report legacy PCI errors like "Parity" and "SERROR". Modern AMD systems use PCIe Advanced Error Reporting (AER), and legacy PCI errors should not be reported. Remove EDAC PCI control setup on AMD Family 17h and later systems.
