I was trying to get frequecy from my device at run time. I used this device node

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

It gave me 60000. I tried this one

cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

I get 396000.

What is the unit of these values. Is it 60000 Hz or Mhz?

  • Also, do note the CPU frequency is likely to change depending on system load. A lower clock speed on the CPU equals power savings. – Criggie Oct 17 '16 at 9:20

The values are given in kHz (see the documentation). So 60000 is 60 MHz, 396000 is 396 MHz.

  • Yes. Thanks. I will look into the documentation from now on. – pointer accurate Oct 17 '16 at 8:40
