Can not enable amd pstate


i want to use amd_pstate driver, too optimize energy consumption and fan noise on my Thinkpad T14 G1 with Ryzen 4650u CPU, which is Zen2. And Zen2 should support amd-pstate, doesn’t it?

i tried “amd-pstate=passive” with “-” instead of “_” and “amd_pstate=active” before with and without “amd_pstate.shared_mem=1” before and it doesnt change a thing.

I dont know, what i have to do, to active that damn driver. Is my cpu not supported or what is going wrong here?

can you post

inxi -Fza
cpupower frequency-info

and check type idle running

sudo turbostat

I seem to have the same issue on my Ryzen 3800X. It used to work until newer kernels. I gave up on it for a while but maybe if someone figures it out I’ll get it working again. :smile:

is there any option CPPC in your UEFI motherboard ?

Okay i got mine working again. I had forgotten i had reinstalled a while back and this is one thing i forgot to set up. I installed cpupower and added amd_pstate=passive to the grub command line and then updated grub with the update grub command and rebooted.

[ricklinux@rick-ms7c37 ~]$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

I am not sure if @Wendigo is using grub or systemd-boot? Then it would be slightly different procedure.

In UEFI there is an option called “cpu power management”. By default it was on. I tried both. It makes no difference. lscpu | grep cppc shows the same output.

yes, i’m using systemd-boot. it is the default for endeavourOs, isn’t it? Maybe i give GRUB i try then. Are you using dracut or mkinitcpio?

I’m using dracut because that is the default now on EOS. If you are using systemd-boot did you add amd_pstate=passive to the kernel command line in /etc/kernel/cmdline? Then you have to reinstall kernels with sudo reinstall-kernels Then reboot and see if the command shows amd-pstate


it seems, that lenovo had not enabled that feature thinkpads of that generation, yet:

try forcing it:

create /etc/modules-load.d/amd-pstate.conf

# Load amd pstate at boot

save file and regenerate initramfs images.
sudo reinstall-kernels
sudo dracut-rebuild

Does not work. I tried blacklisting acpi_cpufreq as well. But no Luck. :slightly_frowning_face:

I could never get it working on my 4700U either. It does work on my 3800X desktop. It also works on my Thinkbook Ryzen 5 5500U. You need to have cpupower installed and then add the kernel parameter and regenerate initramsfs images depending on whether you have grub or systemd-boot.

i tried everything by now. it’s simply not working. and according to several threads in lenovo forums, it seems, that it is not enabled for several models and i don’t believe that will change in the future, considering how old those are today. :face_with_diagonal_mouth:

i guess, i have to stay with acpi-cpufreq.
