The notes I found say to create a file in /etc/modprobe.d
And say call it anything but something like
enable_amdgpu_disable_radeon.conf and put this in it:
options amdgpu si_support=1
options amdgpu cik_support=1
options radeon si_support=0
options radeon cik_support=0
and then do a "dracut --force" and reboot.
Make sure there is not a new kernel, as the dracut will built the
current booted kernel and not the new/other kernels. So make sure you
boot back into the same kernel.
adding --regenerate-all on the dracut command line will cause it to
rebuild all kernel initramfs, I would not do that until you determine
this one works better than the prior one.
si/cik are AMD/ATI graphics cards, The SI and CIK families can use
either driver, default enable is radeon, disable on amdgpu.
I have not rebooted my machine that is using the radeon driver yet (it
is a main server so it does not get booted often), so I don't know if
that is all that is needed for it to work.
