--- Comment #18 from Carlos Santa <carlos.santa at intel.com> ---
The drop in performance (5-10%) due to the presence of the GuC firmware is
still seen when running the benchmarks. The numbers do improve when running it
without the GuC.

This is on top of nightly (Oct 3rd) + Mesa 11.01 + Guc/HuC patch series and
enabling both i915.enable_guc_loading=2 and i915.enable_guc_submission=2.

@Tommy, when you say "Last good + Guc enabled = good" what was the last good
commit? I missed that during my investigation as I thought just introducing the
GuC was the cause.
