From b3c76814ce5b043faa2f07108f1c87ed1cbc8cd1 Mon Sep 17 00:00:00 2001 From: Tao Zhou Date: Tue, 19 Apr 2022 14:45:09 +0800 Subject: [PATCH] drm/amdgpu: add RAS fatal error interrupt handler The fatal error handler is independent from general ras interrupt handler since there is no related IH ring.
