Intel's P-State Driver Does Seem To Be In Bad Shape On Linux 4.6~4.7

A few days ago when delivering benchmarks of the new CPUFreq "Schedutil" governor in Linux 4.7 the P-State comparison results on this Git kernel looked particularly terrible. I've since done some P-State tests on the same system using the Linux 4.5 and 4.6 kernels that further point towards a regression having taken place.

Linux 4.7 CPUFreq Schedutil Testing vs. P-State

With the in-development Linux 4.7 kernel there is a new CPUFreq governor that leverages the kernel's scheduler utilization data in an attempt to make better decisions about adjusting the CPU's frequency / performance state. Here are some benchmarks of that new CPUFreq governor, Schedutil, compared to the other CPUFreq governors as well as the Intel P-State CPU frequency scaling driver.
