AMD just released 1.0 of amdgpu, their new official open-source driver that (I guess) will replace radeon and catalyst in the future. I made a roundup of supported cards from the chip-ids in the driver itself and the developer reference by AMD.

Card List

Official source tree is over here: http://cgit.freedesktop.org/xorg/driver/...eo-amdgpu/

I personally think this is pretty great and makes Linux overall more viable for general use. I think SteamOS might have played a role in the decision to take this step, and it might just pay off.

I myself do not use an AMD GPU right now on my main machine, but have a 5870 in my Steam Machine that might get replaced in the future, and the way things are currently going, probably with either a Pirate or Arctic Islands card.

So, general thoughts and opinions on the topic?
