I’ve only ever seen powersave and performance being supported, on a wide range of laptops. With powersave being the default.

Powersave is noticeably slower on heavy workloads, and performance drains the battery on idle. So you have to keep toggling manually depending on your workload. Gonna try out this tool and hope it works.

Sad it can’t be built into the default governor. It’s not exactly easy to find these settings. There must be a lot of people out there with fancy hardware which they are unaware they are not utilizing to their full potential.

Ondemand was used like 10 years ago, later it was proved that with Intel it is better to use performance (race to idle).

Actually, schedutil (the new ondemand) gets better perf/watt on modern Intel CPUs. Reality is more complex than "always crank up the CPU to the max" or "always turn it down all the way"; schedutil is optimized to do the right thing.

Intel has its custom driver for years now anyways https://www.kernel.org/doc/html/v5.14/admin-guide/pm/intel_p...
