Bug description

After resetting pc the "Performance Level" drop down, sets it self to lowest clocks. After changing it back to auto or highest clocks. This did not happen before. I wonder if its due to KDE changing up the power profile in the core OS.

In my case after PC restart it always sets to "Automatic".

I wonder if its due to KDE changing up the power profile in the core OS.

Can confirm. It's more likely KDE "feature", LACT can do nothing with it

The KDE power profile settings relies on power-profiles-daemon, which to my knowledge does not affect amdgpu, so it must be something else.

However I wasn't able to replicate this issue.

EDIT: this is wrong, it actually does set the performance level: https://gitlab.freedesktop.org/upower/power-profiles-daemon/-/blob/main/src/ppd-action-amdgpu-panel-power.c?ref_type=heads
So it is either power-profiles-daemon itself overriding the setting, or KDE telling it to.
I'm not sure if there's an option to disable ppd from touching amdgpu.

At this rate, we are waiting for the time when the amdgpu driver settings can be configured directly from the KDE settings. That would be cool.

One option to avoid power-profiles-daemon changing the setting would be either to disable it (if you aren't actually using the profiles functionality), or to replace it with tuned. tuned is a service that provides the same dbus interface so it works with the same setting in your desktop, but it's more configurable and doesn't seem to change the performance level on amdgpu by default. It also replaces power-profiles-daemon by default on Fedora 41.
