View source for UCM-iMX95 Yocto Linux: CPU frequency

{{note|The operation below requires '''root''' access.}}

To get the current settings run:
 grep -ir . /sys/devices/system/cpu/cpufreq/policy0/ 2>/dev/null

== The scaling governor==
The scaling governor manages the CPU frequency to balance performance and power consumption dynamically.

To see current scaling governor run:
 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

To see available scaling governors run:
 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_governors

To set the scaling governor run:
 echo userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

== CPU frequency==
{{note|CPU frequency can be changed only when the scaling governor is set to '''userspace'''.}}
To see current CPU frequency run:
 cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

To see available CPU frequencies run:
 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies

To set CPU frequency run:
 echo 900000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed
