APU support in Linux

[nada391]

amdgpu driver is not installed, because APU does not need it (in Ubuntu);
and to my knowledge, there is no proprietary driver for APU;
(there was maybe previously).
if however you meant the packages that get installed by "rocm-opencl-sdk" (you state it is the only that should be installed), those have been uninstalled, since otherwise the GUI would not longer function.

don§t fully understand what you mean by "kernel built in driver do its work" + "manually add radeon repo for rocm only".

PS. amdgpu-install 5.7.3 on Ubuntu 22.04 install gives for "rocm-opencl-sdk" very much more packages as 6.2.3, maybe thats reason that with 6.2.3 it crash.

AMD puts their drivers on the kernel, so technically you don't even need to install the drivers (like nvidia does), all you usually need is software (rocm).
The newer the kernel, the less chance drivers inside of it will support old GPUs. That's why it is not a good idea to be on the bleeding edge software with ancient hardware

with newer kernel 6.8 (jammy) also with rocm 5.7 there are issue;
it would finish one project, then stall , and somehow not return properly from display-sleep.

error like

amdgpu: qcm fence wait loop timeout expired
amdgpu : the cp might be in an unrecoverable state due to an unsuccesful queue preemption

will stop this software on this APU , try again later on a more modern computer;
from what i read, it seems AMD has abandoned developement of proprietary AMD Linux driver, so maybe in future the driver installation can become more easy, hopefully.

They abandoned older generations.
Their driver team is still working on proprietary stuff

In your case I would suggest to just stop folding on your APU.

You're probably thinking of fglrx which they did discontinue. They do have something called amdgpu-pro which is a proprietary userland blob that adds certain functionality to the open source amdgpu driver, but it is not necessary for anything a consumer (or folder) would do.

Linux kernel has amdgpu built in

I received a response from AMD regarding iGPUs and rocm.
Rocm does not support iGPUs officially.
