Hi Kikula, This patch already existed in the drm-intel-nightly branch: commit a8ab5ed5e1bf856eceaab5579236de6f92822b9f Author: Tim Gore <<a href="mailto:tim.gore@intel.com">tim.gore@intel.com</a>> Date: Mon Jun 13 12:15:01 2016 +0100 drm/i915/gen9: implement WaConextSwitchWithConcurrentTLBInvalidate This patch enables a workaround for a mid thread preemption issue where a hardware timing problem can prevent the context restore from happening, leading to a hang. v2: move to gen9_init_workarounds (Arun) v3: move to start of gen9_init_workarounds (Arun) Signed-off-by: Tim Gore <<a href="mailto:tim.gore@intel.com">tim.gore@intel.com</a>> Reviewed-by: Arun Siluvery <<a href="mailto:arun.siluvery@linux.intel.com">arun.siluvery@linux.intel.com</a>> Signed-off-by: Tvrtko Ursulin <<a href="mailto:tvrtko.ursulin@intel.com">tvrtko.ursulin@intel.com</a>> Link: <a href="http://patchwork.freedesktop.org/patch/msgid/1465816501-25557-1-git-send-email-tim.gore@intel.com">http://patchwork.freedesktop.org/patch/msgid/1465816501-25557-1-git-send-email-tim.gore@intel.com</a> Still met the GPU hang issue: [ 114.965619] [drm] stuck on render ring [ 114.970172] [drm] GPU HANG: ecode 9:0:0xfffffffe, in nexuiz-linux-x8 [3252], reason: Engine(s) hung, action: reset [ 114.981934] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
