From 249af7242af72a826dbe93f7058237eee4fac1d6 Mon Sep 17 00:00:00 2001 From: John Harrison Date: Wed, 22 Dec 2021 17:31:28 -0800 Subject: [PATCH] drm/i915/guc: Report error on invalid reset notification Don't silently drop reset notifications from the GuC. It might not be safe to do an error capture but we still want some kind of report that the reset happened.
