Resources shows all CPU cores landlocked at 400MHz
Is there an existing issue for this?
- [x] I searched the existing issues and did not find anything similar.
Current Behavior
Resources shows all processor CPUs locked at 400MHz
Resources is incorrectly using : cpu.rs:249: "/sys/devices/system/cpu/cpu{core}/cpufreq/scaling_cur_freq"
Where it should be using cpu.rs:249: "/sys/devices/system/cpu/cpu{core}/cpufreq/cpuinfo_avg_freq"
scaling_cur_freq does not update on all CPUs and is landlocked at scaling_min_freq.
This behavior has been verified on Lenovo Thinkpad T5xx, Lenovo Thinkpad P53s and DELL Precision T5820 with Intel W-2175 CPU.
This error causes affected users to go on a wild goose chase trying to find a CPU issue that isn't there, thus, a fix is recommended.

Hi, thank you for the issue and your effort to test it using a patch. :) I'll look into it, if I can find a few other smaller issues to squash, this might make it into Resources 1.9.2 then.
Hi, I've pushed a fix to the bugfix/570-cpu-freq-reading branch, mind checking it out?
