Intel P-State Changes Could Improve iGPU-Bound Performance - Some Cases ~15%, ~43% Perf-Per-Watt

This one's all Francisco Jerez—it's been about two years in the making I believe. I've just been watching and am a fan of his work :)

Ok, so congrat him if he's not in the forums

I will have my own soon while Intel's reference values are @ http://people.freedesktop.org/~curro...arison-ICL.log

TL;DR: up to 43% perf improvements, 4~7% avg improvement, less than 1% of loss of perf in the cases where we had losses

I am really excited about these patches, as far as I can tell, CPU power management stealing watts away from the GPU unnecessarily is one of the main differences between Windows and Linux gaming performance myloweslife. This should help a lot. Here's hoping something can land in the kernel.

Bump.
