[Mesa-dev] [PATCH] [rfc] radv: add initial prime support.

I think it would be good to keep the DRI_PRIME switch to allow for
switching between anvil and radv, handy for testing / comparing /
benchmarking both
It seems that Vulkan automatically uses the first card listed in vulkaninfo
(in my case it's the amdgpu card) with no way to select which is used,
hence why I've only been seeing garbage since the radv driver was added
into mesa
If DRI_PRIME=0 is passed will this now automatically use anvil?
Thanks
Mike
