From: Chris Wilson Date: Mon, 8 Apr 2019 09:17:14 +0000 (+0100) Subject: drm/i915/guc: Replace preempt_client lookup with engine->preempt_context X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=174221e8491588aa9d44ebfa3242bea11eacc64f;p=linux.git drm/i915/guc: Replace preempt_client lookup with engine->preempt_context Circumvent the dance we currently perform to find the preempt_client and lookup its HW context for this engine, as we know we have already pinned the preempt_context on the engine.
