Just to be clear - I wasn't suggesting that radeon be blacklisted for Sea Island yet. But, with CONFIG_DRM_AMDGPU_CIK=y set the user then has the option to blacklist radeon and choose amdgpu instead themselves.
I'm a bit afraid, that it will be random at the end, which driver will get active, when two drivers are available. This may result in a lot of confusion. I would like to avoid that by removing support in radeon driver in case we decide to support Sea Islands GPUs via amdgpu driver.
Radeon should load first, since it's listed before amdgpu in the Makefile and kmod respects that order: $ grep -n -e amdgpu -e radeon /lib/modules/`uname -r`/modules.order 361:kernel/drivers/gpu/drm/radeon/radeon.ko 362:kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko So it *should* be safe to have both modules support a range of devices.
