I need to look more carefully at the patch, but automatic zero copy decision is taken in the amdgpu plugin if the program did not have 'requires unified_shared_memory'. If you remove that information from the plugin how can it know that automatic zero-copy needs to be turned on?
At the same time, runtime decision on zero-copy for amdgpu's is based on the machine being an APU, and that is a vendor specific information that cannot be moved to libomptarget.
