	  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.

config DRM_AMD_DC_FP

	  Floating point support, required for DCN-based SoCs

	  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.

	help
	  Choose this option if you want to support secure display

	  This option enables the calculation of crc of specific region via
	  debugfs. Cooperate with specific DMCU FW.
