Does Mellanox NIC's 5.X support RDMA when IOMMU is enabled on systems?

I am trying to configure a test system with AMD CPU’s, Mellanox NICs and a GPU (AMD or Nvidia) to perform RDMA. The system needs to have IOMMU enabled.

Perform RDMA from GPU memory

Perform RDMA from system memory

Lastly, does Mellanox have a PCIe reference card that can be used to test system setup for functionality and performance.
