From 2010b7f0a8521fa7463056c8f077277a33a45c5f Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 28 May 2020 21:57:27 +0100 Subject: [PATCH] drm/i915/gt: Start timeslice on partial submission We may choose to only submit ELSP[0], even though we have sufficient requests to fill the whole ELSP. Normally, we only start timeslicing if we fill more than one port, but in this case we need to start timeslicing for the queue that we choose not to submit.
