AF_XDP, which can be regarded as an upgraded version of AF_PACKET, can provide more than 10 times performance improvement. It can also connect the XDP pass-through to user-space directly, which means an ebpf program that processes packets can be forwarded to an application in a very efficient way. Thus enabling a delicate PMD for AF_XDP is valuable for DPDK applications to benefit from it. In this presentation, we will share our recent work about enabling a DPDK Polling Mode driver for AF_XDP. Firstly, we will briefly introduce AF_XDP and why we need a DPDK PMD driver for AF_XDP. Then we will present the implementation details on how to translate AF_XDP language (XDP socket, ebpf redirect map…) into DPDK language (ethdev, queue), how to reach zero copy between rte_mempool and XDP umem, and so on. At last, we will share some ideas for future improvement such as utilizing the busy poll feature to improve performance.
