Monitoring CPU temperature and clock speeds

korinel · Posted at 3/29/2017 15:42:20

Hi,

Would it be possible to get some information regarding how to monitor CPU temperature and clock speeds of the RK3399 running Ubuntu? The usual lm_sensors solution doesn't seem to work.

Thanks,

-Karl

Found what I needed:

cat /sys/devices/system/cpu/cpufreq/policy?/cpuinfo_cur_freq /sys/devices/virtual/thermal/thermal_zone?/temp

Copy the code

I'm assuming that thermal_zone0 is the CPU. thermal_zone2 looks like it's in different units, and perhaps not connected to anything. Any clues as to what thermal_zone1 is?

0 for cpu, 1 for gpu.
