13 select DRM_AMD_DC_FP if ARCH_HAS_KERNEL_FPU_SUPPORT && !(CC_IS_CLANG && (ARM64 || LOONGARCH || RISCV))
15 Choose this option if you want to use the new display engine
16 support for AMDGPU. This adds required support for Vega and
19 calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 ||
20 ARM64 || LOONGARCH || RISCV) architectures built with Clang (all released
21 versions), whereby the stack frame gets blown up to well over 5k. This
22 would cause an immediate kernel panic on most architectures. We'll revert
23 this when the following bug report has been resolved:
24 https://github.com/llvm/llvm-project/issues/41896.
29 Floating point support, required for DCN-based SoCs
32 bool "AMD DC support for Southern Islands ASICs"
33 depends on DRM_AMDGPU_SI
36 Choose this option to enable new AMD DC support for SI asics
37 by default. This includes Tahiti, Pitcairn, Cape Verde, Oland.
38 Hainan is not supported by AMD DC and it has no physical DCE6.
40 config DEBUG_KERNEL_DC
41 bool "Enable kgdb break in DC"
45 Choose this option if you want to hit kdgb_break in assert.
47 config DRM_AMD_SECURE_DISPLAY
48 bool "Enable secure display support"
50 depends on DRM_AMD_DC_FP
52 Choose this option if you want to support secure display
54 This option enables the calculation of crc of specific region via
55 debugfs. Cooperate with specific DMCU FW.
