From 2bfbf6fed1a0f672726b0637b89b44d94dedd2b6 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 3 Sep 2018 09:33:33 +0100 Subject: [PATCH] drm/i915: Do a full device reset after being wedged We only call unset_wedged on the global reset path (since it's a global operation), so if we are terminally wedged and wish to reset, take the full device reset path rather than the quicker individual engine resets.
