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-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 > v5.1, and packed ring multi-queues not support reconnect in qemu yet. -2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version >= 5.2.0, dut to old qemu exist reconnect issue when multi-queues test. -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, and the suite has not yet been automated. - -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.
