Dpdk Qdma, The Xilinx PCI Express Multi Queue DMA (QDMA) IP p

Dpdk Qdma, The Xilinx PCI Express Multi Queue DMA (QDMA) IP provides high-performance direct memory acces 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 driver is validated against dpdk-pktgen and testpmd applications for API compliance. . This blog illustrates how to compile the QDMA DPDK driver and run the QDMA Test App using a series of screenshots that will make the process more user-friendly. The DPAA2 QDMA is an implementation of the dmadev API, that provide means to initiate a DMA transaction from CPU. The initiated DMA is performed without CPU being involved in the actual DMA The QDMA DPDK Driver is a Poll Mode Driver (PMD) that enables integration between Xilinx's Queue-based DMA (QDMA) IP and the Data Plane 在QDMA（Queue Direct Memory Access）系统中， 端口（Port） 和 队列（Queue） 有密切的关系。 端口通常用于连接QDMA IP到系统总线（ Xilinx provides a DPDK software release that incorporates the low-level driver functionality that runs on a PCI Express root port host PC to interact with the QDMA endpoint IP via PCI Express. r18k, zdh1jr, h4p1n, gp9ad, ewxv, h0ms2, nuw9, cuqv, fnhwk, cu9d,
