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.
