CONFIG_CPU_FREQ_GOV_SCHEDUTIL: 'schedutil' cpufreq policy governor

General informations

The Linux kernel configuration item CONFIG_CPU_FREQ_GOV_SCHEDUTIL has multiple definitions:

'schedutil' cpufreq policy governor found in drivers/cpufreq/Kconfig

The configuration item CONFIG_CPU_FREQ_GOV_SCHEDUTIL:

Help text

This governor makes decisions based on the utilization data provided by the scheduler. It sets the CPU frequency to be proportional to the utilization/capacity ratio coming from the scheduler. If the utilization is frequency-invariant, the new frequency is also proportional to the maximum available frequency. If that is not the case, it is proportional to the current frequency of the CPU. The frequency tipping point is at utilization/capacity equal to 80% in both cases.

If in doubt, say N.
