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 VM2VM virtio-user topology. +1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check. +2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test and payload check. +3. Test indirect descriptor feature. For example, the split ring mergeable inorder path use non-indirect descriptor, the 2000,2000,2000,2000 chain packets will need 4 consequent ring, still need one ring put header. +the split ring mergeable path use indirect descriptor, the 2000,2000,2000,2000 chain packets will only occupy one 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.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. + +Prerequisites +============= + +Topology +-------- + Test flow: Virtio-user -> Vhost-user -> Testpmd -> Vhost-user -> Virtio-user + +General set up +-------------- +1.
