Specifically, one vring can use multiple different DMA +channels and one DMA channel can be shared by multiple vrings at the same time.Vhost enqueue and dequeue operation with CBDMA channels is supported +in both split and packed ring. + +This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-net topology. +1. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring +vhost-user/virtio-net mergeable path. +2.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring +and packed ring vhost-user/virtio-net mergeable and non-mergeable path. +3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring. + +IOMMU impact: +If iommu off, idxd can work with iova=pa +If iommu on, kernel dsa driver only can work with iova=va by program IOMMU, can't use iova=pa(fwd not work due to pkts payload wrong). + +Note: +1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet. +2.For split virtqueue virtio-net with multi-queues server mode test, better to use qemu version >= 5.2.0, dut to qemu(v4.2.0~v5.1.0) exist split ring multi-queues reconnection issue. +3.When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may +exceed IOMMU's max capability, better to use 1G guest hugepage. +4.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. + +Prerequisites +============= + +Topology +-------- + Test flow: Virtio-net <-> Vhost-user <-> Testpmd <-> Vhost-user <-> Virtio-net + +Software +-------- + iperf + qemu: https://download.qemu.org/qemu-6.2.0.tar.xz + +General set up +-------------- +1.
