[Bug 1885730] Re: Please switch default, hwe, oem kernel flavours governor to CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y , such that advanced userspace utilities such as game-mode can be later used to rev-up to to performance, or rev-down to powersave.

[Julian Andres Klode]

For example, the measurements on the X220 do not reflect situation on
modern Intel systems, as they scale differently from Skylake and newer,
as they do not have HWP.

A CPU with HWP (hardware P-states) behaves as you'd expect sort of - it
runs at close to max frequency all the time, and scales down extremely
in non-performance modes. It scales up and down faster than older
models, given that HWP does the frequency scaling inside the CPU.

Disabling HWP gives you X220-style old scaling which is slower, and does
not go as far down as the HWP scaling.
