Hi,
Currently schedutil does not populate all stats like ondemand does, which can
be a problem for some monitoring software.
On my AMD 3000G CPU with kernel-5.9.1:
grep. /sys/devices/system/cpu/cpufreq/policy0/stats/*
With ondemand:
time_in_state:3900000 145179
time_in_state:1600000 9588482
total_trans:177565
trans_table: From : To
trans_table: : 3900000 1600000
trans_table: 3900000: 0 88783
trans_table: 1600000: 88782 0
With schedutil only two file exists:
reset:<empty>
total_trans:216609
I'd really like to have these stats populated with schedutil, if that's
possible.
Thanks.
