How get opecl working on amdgpu

Hello everyone. Anyone have any good experience with opencl on amdgpu? After searching, I did not find a solution. There is only rocm, which requires hardware support from the processor and motherboard. Maybe someone has a working config with amdgpu-pro or opencl-mesa? My e5-2670v1 processor does not support atomics, so rocm does not work.
