From 4b3a999e23ca1b823cc66261b1b7e6fbf68cd02b Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Sun, 26 Sep 2021 20:45:45 +0200 Subject: [PATCH] drm/i915/guc: Move and improve error message for missed CTB reply If we timeout waiting for a CT reply we print very simple error message. Improve that and by moving error reporting to the caller we can use CT_ERROR instead of DRM_ERROR and report just fence as error code will be reported later anyway.
