Comment 9 Jaroslav Škarvada 2021-07-07 21:41:46 UTC

I have a bit problem with the name 'balanced', because it uses 'min_perf_pct=100'. Currently, we set the throughput-performance profile as the default nearly everywhere. What's the benefit of switching to this profile? In the past we got feedback that there are just too much profiles, so is there any benefit why to introduce another one? The current balanced profile doesn't have better performance, but it should exhibit lower power consumption (e.g. it doesn't have 'min_perf_pct=100').

In upstream we are trying to get rid of the sched_* tuning, namely:

kernel.sched_min_granularity_ns = 2250000
kernel.sched_wakeup_granularity_ns = 15000000
kernel.sched_migration_cost_ns=50000
kernel.sched_latency_ns=6000000

Are these tuning needed?
