From 5e32d7482ee20738d3474151f365b0a522fba463 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 21 Jul 2017 13:32:25 +0100 Subject: [PATCH] drm/i915: Clear execlist port[] before updating seqno on wedging When we wedge the device, we clear out the in-flight requests and advance the breadcrumb to indicate they are complete. However, the breadcrumb advance includes an assert that the engine is idle, so that advancement needs to be the last step to ensure we pass our own sanity checks.
