Hello,
can anyone help regarding installing of cpupower ? I have AMD Ryzen 5700u, and I entered "modprobe amd-pstate". No any error.
But I can't see if amd pstate is in use or not. And I can't see what is my cpu frequency.
Thank you.

Please, can anyone help regarding install of Cpu-power ?
Can I blacklist cpufreq driver in order to activate amd pstate ?

Hello Dj
As l'am not an AMD user, I can't help you much.
You could start indeed with blacklist the concern module as you mentioned before
Good luck

After checking the kernel config file, I see that CPU_FREQ is hardcoded.
Maybe it's a problem or no. Let me know.

I have installed TLP and modprobed amd-pstate.
So far, so good.
Any plans to put cpupower in repos ? It's quite uncommon to see distributon without cpupower.

Will look at it.

Since there is no cpupower, I have been using tlp. Active governor is shedutil
/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver = amd-pstate
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor = schedutil
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors = conservative performance schedutil
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq = 400000 [kHz]
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 2100000 [kHz]
Тhere is no accurate reading of cpu, it's showing max frequency of 2. ghz.
How to change cpufreq governor ?

In case someone is interested - TLP is blocking CPU frequency, so with installed TLP, Cpu is 2ghz instead of 4 ghz. Only way that I found is to disable TLP.
