Switching from radeon to amdgpu

I came across this post while browsing some stuff, and would like to add a comment.

I happen to be using a much older GCN-1 card, Radeon 8670M, and I’m currently on Fedora 39 GNOME with kernel 6.8.4

Now I looked up your card which is GCN-2 and whose codename is Sea Islands (cik, my card being GCN-1 is codenamed Southern Islands, si).

Now this is how I set up the args on my machine:

  1. sudo nano /etc/default/grub
  2. I add the args to this line - GRUB_CMDLINE_LINUX="radeon.si_support=0 amdgpu.si_support=1"
  3. Ctrl + O (not zero, alphabetical O) to save the file
  4. sudo grub2-mkconfig -o /boot/grub2/grub.cfg
  5. Reboot

For your case, I think the process should be the same, instead of radeon.si, you’ll type radeon.cik in the above mentioned GRUB_CMDLINE_LINUX= line.

Then again I’m no expert in these matters and I’m using the Fedora 39 Workstation whereas you’re using Kinoite, so whether or not this will work on your system, I can’t say for sure.

Please post a comment if this works.
