Chris, Mika, I wonder does i915 driver tries to keep CPU in C0 at the
moment already or you just consider this? If it is doing anything to
CPU while gpu is busy, could you, please, clarify what exactly and
point me to the code/key patches? Please, answer from BDW/SKL gen
perspective rather than VLV.
Dmitry.
