13	  support for AMDGPU. This adds required support for Vega and

16	  calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)
17	  architectures built with Clang (all released versions), whereby the stack
18	  frame gets blown up to well over 5k.  This would cause an immediate kernel
19	  panic on most architectures.  We'll revert this when the following bug report
20	  has been resolved: https://github.com/llvm/llvm-project/issues/41896.
