Overclocking

[pfeerick]

Which command gets you the current clock speed and with which command can you change the clock speed?

PS Why don't we make a fork of raspi-config called pine64-config for these kind of things?

CPU clock speeds? 

To get the current clock speed:

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

To alter the current minimum and maximum frequencies (sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies to see valid options):

echo 480000 | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
echo 1152000 | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

To change the CPU governor (sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors to see available governors):

echo interactive | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

On the pine64-config front, Terra854 has been busy putting together exactly that. I had a quick look at it, and it seems like a solid start to a useful config tool for the pine64. I did encounter a bug on the DietPi debian distro where it wouldn't install cpufrequitils in order to have a nice tool to change the cpu govenour, but you can fix that easily by running apt install cpufrequtils.
