Some AMD GPUs have hardware support for grapics SRIOV. If the GPU has a display output then the GPU needs to support Legacy VGA operation. If CLASS_CODE = VGA then the device should have a Port Type = Legacy EndPoint. Therefore in order to enable SRIOV on a GPU with a display output LEGACY_END_POINT is supported as a valid Port Type.
