From d6c0511300dcff19969844495ba293c4efb50b42 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 3 Oct 2017 21:34:47 +0100 Subject: [PATCH] drm/i915/execlists: Distinguish the incomplete context notifies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let the listener know that the context we just scheduled out was not complete, and will be scheduled back in at a later point. v2: Handle CONTEXT_STATUS_PREEMPTED in gvt by aliasing it to CONTEXT_STATUS_OUT for the moment, gvt can expand upon the difference later.
