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

21 calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 ||
22 ARM64 || LOONGARCH || RISCV) architectures built with Clang (all released
23 versions), whereby the stack frame gets blown up to well over 5k. This
24 would cause an immediate kernel panic on most architectures. We'll revert
25 this when the following bug report has been resolved:
