From: Chris Wilson Date: Fri, 6 Jul 2018 07:53:06 +0100 Subject: drm/i915: Squelch very verbose error logging Git-commit: 1eca65d922d7543b60610624afd345b4f3d71ae2 Patch-mainline: v4.19-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 Having found the error causing the IGT test to fail, downgrade the verbose logging so that we stop flooding the syslogs as we deliberately provoke it many thousands of time during selftests.
