I found that 'tuned-adm profile latency-performance' is not work on Ubuntu 20.

because of latency-performance need to set kernel
sched_min_granularity_ns = 10000000
sched_migration_cost_ns = 5000000

but While with kernel 5.13, these variables is missing.

according to

https://forum.endeavouros.com/t/sysc...5-13-why/17097

and I try to set these on /sys/kernel/debug/sched
but it is useless.

so how can I use latency-performance on Ubuntu 20.
