From 506927ec8bbbdd99261cec4cd28cd0fd54e02218 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 12 Jul 2019 09:25:49 +0100 Subject: [PATCH] drm/i915/selftests: Ignore self-preemption suppression under gvt GVT forces single port submission of individual requests. We do not enjoy the context amalgamation that the test depends upon for setting up the test (where port 0 has a large number of requests with a priority change somewhere in the middle). Under single request submission of gvt it is quite able for the preemption event to occur while another context is active and so there be a real need to act upon that preemption.
