Imho it's time we provide a "hardware enablement" backport of the graphics stack, not only for users, but also to thank AMD for their new phase of GPL-friendly driver development. This will also require a backport of llvm-10-toolchain. The only thing I'm not sure about is if additional Xorg components would additionally need to be backported. I've CCed the backports list and the teams involved. Cheers, Nicholas
