It seems a little odd that a Linux distribution with a gaming focus doesn't have any way to configure AMDGPU video cards. I'd personally really appreciate having this in the repository, so I could manage my 480 in a way similar to the official drivers on Windows.
Yes! Under GPL-2.0.
Who will use this?
Those who wish to have more control over their Radeon cards, as they would on Windows. Overclockers, undervolters, those who like custom fan curves, et cetera.
