Thanks for you relay,depend on general-purpose of drivers development,AMDGPU
should work on 32bit arch.But I don't know what wrong with it.The AMDGPU driver
for me lack of kfd ,APU node topology and   amdgpudrmfb(fb0 interface),I want
to know how to fix it. The firmware and kernel is nearly newest ,but 5.10.9 do
more things on resetting the GPU, show more debug information than 5.8.0.
