on most CPU you can use cpufreq-aperf to check cpu frequency, but I don't think this is compatible with AMDGPU.I did check for aperf and found:$ cat /proc/cpuinfo | grep -o aperf[a-z]* | head -1aperfmperfAttempt to use cpufreq-aperf:$ sudo cpufreq-aperfError reading /dev/cpu/0/msr, load/enable msr.ko$ sudo modprobe msr$ sudo cpufreq-aperfCPU Average freq(KHz)   Time in C0  Time in Cx  C0 percentage000 [offline]001 [offline]002 [offline]003 [offline]Am I missing something, or is this tool incompatible with AMDGPU? (I have an A10-8700P). The fact that msr is not autoloaded makes me thing it's not compatible.So is there another tool I can use, or am I missing something?Reason I want this, is i've enabled powerplay and I'd like someway to see the effect (other than running benchmarks).Update, I think it maybe related to a module I have loaded that I may need to remove?These are my modules;Module                  Size  Used

AMDGPU CPU Query Frequency
cpu;amd graphics;cpu frequency;amd
Fixed,I went back to a kernel with a custom DSDT override, this enabled the cpu frequency.
