Active *development* is happening on GCN GPUs supported by amdgpu. Keep in mind that our "legacy" port is.. well.. legacy *in terms of porting= *. It's manually ported instead of writing a compatibility layer which is h= ow the current port works. The legacy port is stuck on older Linux code because of that, but *Linux di= d not drop support for older GPUs in the same drivers* so the new port shou= ld work just as well.
