13 Choose this option if you want to use the new display engine
14 support for AMDGPU. This adds required support for Vega and
17 calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)
18 architectures built with Clang (all released versions), whereby the stack
19 frame gets blown up to well over 5k. This would cause an immediate kernel
20 panic on most architectures. We'll revert this when the following bug report
21 has been resolved: https://github.com/llvm/llvm-project/issues/41896.
26 Raven, Navi, and newer family support for display engine
28 config DRM_AMD_DC_HDCP
29 bool "Enable HDCP support in DC"
32 Choose this option if you want to support HDCP authentication.
35 bool "AMD DC support for Southern Islands ASICs"
36 depends on DRM_AMDGPU_SI
39 Choose this option to enable new AMD DC support for SI asics
40 by default. This includes Tahiti, Pitcairn, Cape Verde, Oland.
41 Hainan is not supported by AMD DC and it has no physical DCE6.
43 config DEBUG_KERNEL_DC

51 bool "Enable secure display support"
53 depends on DRM_AMD_DC_DCN
55 Choose this option if you want to
56 support secure display
58 This option enables the calculation
