Scaling_governor

[∞lan∞]

Подскажите пожалуйста как переключиться на schedutil чтоб постоянно, если это возможно.

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Если по-умолчанию работает intel_pstate, перед использованием acpi-cpufreq, intel_pstate нужно запрещать параметром ядра.

# grep intel_pstate /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz root=UUID=UUID ro acpi_backlight=vendor resume=/dev/disk/by-uuid/UUID panic=30 intel_pstate=disable

Вот это не имеет значения и оно ничем не поможет.

А нельзя ли проще сделать, не трогая вообще /etc/sysfs.conf?
Как-нибудь так:

Можно.

Это не проще.

Зато работает. Надеюсь, что это так.
Иначе все равно ondemand если добавлять строки
