Description

The schedutil cpu frequency governor is more tightly coupled to userspace activity and performs more granular cpu frequency changes. I've personally be using it for years. I think it's prudent to change to this default.. especially given cpu-frequency utils is deprecated and no-longer enabled by default on armbian builds.

I think if this is merged it's an opportunity to also remove some of the unmaintained on-demand governor tweaks in armbian-hardware-optimize as well.

Quoting the kernel docs:

This governor generally is regarded as a replacement for the older ondemand and conservative governors (described below), as it is simpler and more tightly integrated with the CPU scheduler, its overhead in terms of CPU context switches and similar is less significant, and it uses the scheduler's own CPU utilization metric, so in principle its decisions should not contradict the decisions made by the other parts of the scheduler.
