When will they just give this up already? It's been years and years, and still sucks, and beyond still being bad, it's trying to replace options that are actually good. Performance, powersave, even ondemand. Schedutil is just overcomplicated and underperforming.

AMD Schedutil vs. Performance Governor Benchmarks On Linux 5.11 Shows More Upside Potential

Schedutil was about as fast as ondemand in the last PHX benchmarks I've seen. The performance varied based on the specific tests but overall I think that schedutil even came out slightly ahead. With the recent improvements it'd probably outperform ondemand. If they manage to fix the utilization calculation properly for 5.12 I'd be an interesting benchmark.

Why can't Linux enter the 21th century and implement continuous integration like everyone else? Obviously you can't test everything but some regressions are simply too obvious to be ignored.## VGA ##

Overall... I'm still not impressed by schedutil, not at all. A CPPC2 based scheduler has some intrinsic advantages and should result in some actually tangible differences. Hope we'll see it some day.

I want a CPU governor that ignores "nice" load.
Edit: Some searching later:
