From 2c170af76cd77258ff41d7270a281e23c386c649 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 30 Mar 2017 15:50:36 +0100 Subject: [PATCH] drm/i915: Do request retirement before marking engines as wedged As we declare an engine as wedged, we mark all of its active requests as in error. However, we don't want to mark successfully completed requests as in error, which requires us to retire those requests first.
