I'm using amdgpu on FreeBSD (-CURRENT, drm-next-kmod), with Vulkan (RADV) + Wayland, it's awesome :)

Yeah, OpenCL is a problem, clover crashes, the new AMD OpenCL driver is not ported yet (I guess it depends on kernel 4.15? we have amdgpu from 4.12 for now)...

I wish people started using Vulkan for compute instead of OpenCL!!
