@Rafael: Will it be fine to lower down the value of LATENCY_MULTIPLIER?
We can do that, but then I think we need to compensate for the change in the old governors code or there may be surprises.
Why shouldn't we change the value of LATENCY_MULTIPLIER for old governors as well? They use the same calculations and the sampling rate there is also this bad (like rate_limit_us).
On some systems. On other systems it isn't.
If we aren't going to change that for old governors, then we can create a local version of LATENCY_MULTIPLIER for schedutil I believe.
OK, so at least for intel_pstate and acpi-cpufreq we want a 10 ms default which is what we have currently.
If you want to rework all that, make sure you preserve that.
Thanks, Rafael
