Subject: [PATCH] drm/amd/display: fix non-x86/PPC64 compilation
Date: Wed, 6 Jul 2022 17:42:03 -0400 [thread overview]
Message-ID: <20220706214203.555342-1-alexander.deucher@amd.com> (raw)
Need to protect FP DMCUB code with CONFIG_DRM_AMD_DC_DCN.
Fixes build failures like the following on arm64:
ERROR: modpost: "__floatunsidf" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "__divdf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "fma" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "__adddf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "__fixdfsi" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "__muldf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!

ERROR: modpost: "__fixunsdfsi" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
