Given how tricky it is to get these governors working I suspect there may be work required to make schedutil functional. In the active mode it uses its own internal performance scaling governor algorithm or allows the hardware to do performance scaling by itself while in the passive mode it responds to requests made by a generic CPUFreq governor implementing a certain performance scaling algorithm.

First it uses information provided by the scheduler directly for making its decisions. LITTLE systems. Features Kernel v4. Distributions like Ubuntu Fedora and Manjaro are beginning to use CPUFreq Schedutil by default on newer kernels and thus leading to a very bad initial out of the box experience with the current Download ATOM X KERNEL EAS for free. It is boosted to 50 upon touch event for 3 seconds. It 39 s useful to have bots automatically test proposed patches and notify authors when they fail to compile in certain configurations. While schedutil is used on mobile devices it still doesn 39 t see much use on x86 desktops the intel_pstate governor is generally seen giving better results on those processors as a result of the secret knowledge embodied therein.
