Hi,
Building an arm64 allmodconfig kernel from todays next tag, next-20220811. I can see the following build error.
ERROR: modpost: "dc_dsc_compute_bandwidth_range" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! ERROR: modpost: "dc_dsc_get_policy_for_timing" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
When I reverted this patch I was able to build an arm64 allmodconfig kernel.
Cheers, Anders
