<pre>drm-tip RC kernel integration drops offscreen 3D tests performance to 1/3rd:
kernel git://anongit.freedesktop.org/drm-tip at
10de1e17faaab452782e5a1baffd1b30a639a261 2017-07-18_10-09-14 drm-tip:
2017y-07m-18d-10h-08m-42s UTC integration manifest
Because kernel doesn't anymore raise GPU speed from minimum (to maximum) with
those tests, as it should.
These tests include offscreen versions of following:
* GfxBench 4.0 ALU2, Tessellation, T-Rex, CarChase
(neither Manhattan, nor CPU bound driver tests were affected)
* GLBenchmark 2.7 Egypt, T-Rex and Fill tests (Fill least)
This issue is BYT specific.</pre>
