Choose this option if you want to use the new display engine
support for AMDGPU. This adds required support for Vega and
Raven ASICs.
calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)
architectures built with Clang (all released versions), whereby the stack
frame gets blown up to well over 5k. This would cause an immediate kernel
panic on most architectures. We'll revert this when the following bug report
has been resolved: https://github.com/llvm/llvm-project/issues/41896.

Choose this option to enable new AMD DC support for SI asics
by default. This includes Tahiti, Pitcairn, Cape Verde, Oland.
Hainan is not supported by AMD DC and it has no physical DCE6.
