From 676d8c24f3e825484085d10fc1768cab46ed5166 Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Thu, 17 Mar 2016 13:57:09 +0800 Subject: [PATCH] drm/amdgpu: use sched fence if possible when preemption feature lands, the SA bo should rely on sched fence, because hw fence will be invalid after its job preempted or skipped.
