This is a test MI210.  

New to AMDGPU, having used  CUDA in the past.

Hi @joelandman-jt! This occurs because the version of the ROCm stack (specifically the ROCR library) that we ship with AMDGPU.jl is somewhat old and doesn't know about newer GPUs (his issue also occurs with the MI200). If you have a newer (>= 4.5.2) ROCm install on your system (or can get it installed via your distribution's package manager), then you can set the environment variable JULIA_AMDGPU_DISABLE_ARTIFACTS=1 and re-build AMDGPU.jl (using Pkg; Pkg.build("AMDGPU"), and then AMDGPU.jl will detect and use your system ROCm install.

I'll also be building JLLs for ROCR 4.5.2 soon, which should alleviate this issue.

We now use much newer versions so this should be fine.
