Information

ondemand governor

root@pinenote:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
408000 600000 816000 1104000 1416000 1608000 1800000

  • 816 MHz:

    cpufreq-set -u 816000; cpufreq-set -u 816000; cpufreq-info

  • 1.10 GHz:

    cpufreq-set -u 1104000; cpufreq-set -d 1104000 ; cpufreq-info

    Better use?:

    cpufreq-set -u 1104000; cpufreq-set -d 816000 ; cpufreq-info

  • 1.61 GHz:

    cpufreq-set -u 1608000; cpufreq-set -u 1608000; cpufreq-info

  • 1.8 Ghz:

    cpufreq-set -u 1800000; cpufreq-set -d 1800000 ; cpufreq-info

TODO

  • Check with other governors, maybe there is one that yields good performance
