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 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 loopback virtio-user topology. +1. Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched, +virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed. +This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes split ring mergeable, non-mergeable, inorder mergeable, +inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable, vectorized path. +2. Check payload valid after packets forwarding many times. +3. Stress test with large chain packets. + +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. 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. +2. DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd, and the suite has not yet been automated. + +Topology +-------- + Test flow: Vhost-user <-> Virtio-user + +General set up +-------------- +1.
