Yes its fine, I am just wandering if this option is enabled by bios ? How ?
In sys these values are listed on a per cpu basis.
To list possible governors: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_governors
To view current governor cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
To enable the demand base power management in kernel, You can set the "Ondemand Governor" as an active governor in kernel with below command, echo ondemand > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
Also, if using gnome you can add to your panel the "CPU Frequency Monitor" which allows the user to adjust these settings
