From 939fd762083f988be271da8c96398178daf9baf0 Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Thu, 30 Jan 2014 19:04:44 +0200 Subject: [PATCH] drm/i915: Get rid of acthd based guilty batch search As we seek the guilty batch using request and hangcheck score, this code is not needed anymore. v2: Rebase.
