From ca98317b89428e6ac17be0938b467ed78654dd56 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 20 Mar 2018 10:04:48 +0000 Subject: [PATCH] drm/i915: Specify which engines to reset following semaphore/event lockups If the GPU is stuck waiting for an event or for a semaphore, we need to reset the GPU in order to recover. We have to tell the reset routine which engines we want reset, but we were still using the old interface and declaring it as "not-fatal".
