15 Choose this option if you want to use the new display engine
16 support for AMDGPU. This adds required support for Vega and
17 Raven ASICs.

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