From 16a8739402a004de7283c33427150f7189fccf4f Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 20 Dec 2017 09:06:26 +0000 Subject: [PATCH] drm/i915: Tidy up GEM_TRACE around execlists Looking at the coordination of resets with the submission of execlists, it will be useful to have a GEM_TRACE for when we issue the reset. Whilst there tidy up the other GEM_TRACE to always include the engine name, and be careful not to trust any pointers prior to asserts.
