The Xilinx PCI Express Multi Queue DMA (QDMA) IP provides high-performance direct memory access (DMA) via PCI Express. The PCIe QDMA can be implemented in UltraScale+ devices. Both the linux kernel driver and the DPDK driver can be run on a PCI Express root port host PC to interact with the QDMA endpoint IP via PCI Express. The software approach - through Linux and the Xilinx drivers - has enough documentation scattered around to make work, if you have a lot of patience. But the only speed reference I could find for it is this Z-7030 benchmark of 84.7MB/s. I found nothing for the newer ZU+, with the XDMA PCIe Bridge driver.
