echo 792000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
The frequency 792000 is in KHz, which is 792 MHz.
The maximum frequency can be checked by using this command:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Use the following command to view the current CPU frequency in KHz:
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
Use the following command to view available governors:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
Use the following command to change to interactive CPU frequency governor:
echo interactive > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
