When we tried to compile DCN32/321 for 32-bit architecture, we got this error message:
ERROR: modpost: "__floatunsidf" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! This was caused because we were trying to assign an unsigned int to a double value which causes issues for 32-bit architecture. This issue can be fixed by changing the value type.
