From 5d031f4e1618b64344713b8e4f864a6ccc1f31cf Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 12 Oct 2017 21:40:19 +0100 Subject: drm/i915: Stop asserting on set-wedged vs nop_submit_request ordering Since the removal of the stop_machine(), it is allowed and expected for the nop_submit_request() and nop_complete_submit_request() to run in parallel to the i915_gem_set_wedged() processing. As such we can no longer assert that i915_gem_set_wedged() has completed inside the stop_machine prior to the individual nop_submit_request execution.
