Solved: Problems with hardware tweaks on OSTree

I have an AMD CPU which I would like to undervolt on Battery and also disable some cores, as batterylife is pretty underwhelming, compared to my 2012 intel Thinkpad with the same capacity.

There is RyzenAdj with a COPR that I would use.

Also the temps are extremely high as the Fan is set way too passively, I would like to change them but this also doesnt work.

/v/h/user ❯❯❯ ryzenadj --power-saving
pcilib: Cannot open /sys/bus/pci/devices/0000:00:00.0/config

/v/h/user ❯❯❯ sudo pwmconfig

# some outputs, pressing yes

hwmon3/pwm1_enable stuck to 2
Manual control mode not supported, skipping hwmon3/pwm1.
There are no usable PWM outputs.

I guess the problem is, that these components are controlled in a read-only area? Is there any chance to symlink that to something writable, or use a different directory? Especially on Laptops the default just doesnt work that well.

Okay wow. The solution was just to run the commands with sudo.

So I can confirm Ryzenadj (COPR) works on Kinoite! Also I can disable CPU cores (as far as this is possible on x86) and in theory use layered TLP or other tools.

Havent found a way to toggle TDP or undervolt the CPU and GPU for now though, which would be great.

Tweaking it to that extent is huge, I have double the battery life with no speed difference for regular actitivies.

One should (with many systems) be able to adjust CPU voltage from within the bios. That seems part of over/under clocking. I don’t know about GPU voltages.

Not possible with stock Thinkpad Bios… on my old one with 1vyrain yes, but also not really useful as its so old
