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.
