NVIDIA Poll Mode Driver (PMD) is an open-source upstream driver embedded within dpdk.org releases that’s designed for fast packet processing and low latency. It achieves this by providing a kernel bypass for send and receive queues and by avoiding the performance overhead of interrupt processing.
The NVIDIA PMD mlx5 is for ConnectX-4 Lx, ConnectX-5, ConnectX-5 Ex, ConnectX-6, ConnectX-6 Lx, ConnectX-6 Dx, and NVIDIA BlueField®-2 Ethernet adapters SmartNICs and data processing units (DPUs). NVIDIA PMD support bare-metal, Kernel-Based Virtual Machine (KVM) and VMware SR-IOV on x86_64, Arm, and Power architectures.
