As per the title, I’m using my framework 16 with dgpu in sort of a desktop configuration. The issue I’ve run into withing Fedora 41 is that some things start slow and it seems to be related to the dgpu power down/up cycle from the logs:

Nov 14 09:15:50 kernel: amdgpu 0000:03:00.0: amdgpu: SMU is resumed successfully!
Some start lag observed from the power cycle:
- Chrome with graphics acceleration enabled has initial scroll lag.
- Opening something like gnome settings from an idle system will have lag
Is the best option here to disable amd power management on the kernel commandline or are there any less heavy handed approaches?
