the entry in /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq (maybe the path is wrong, I haven't the machine and I'm going by memory) is readable only by root so it is not usable to a normal user to display the current frequency of the processor, 

 

There is a way to change this behaviour?

 

My distribution is for Olimex-A20-Micro with legacy kernel 5.14 if i don't go wrong.

 

TIA and regards

 

 

I think this is intended, you can read current frequency via

/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

instead of

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

 

The difference between two values is explained here.

Thanks, i will try this value asap.
