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 QDMA shell includes a high-performance DMA that uses multiple queues optimized for both high bandwidth and high packet count data transfers. The QDMA shell provides. * Streaming directly to continuously running kernels * High bandwidth and low latency transfers * Kernel support for both AXI4-Stream and AXI4 Memory Mapped.
