Specifically, one vring can use multiple different DMA\n-channels and one DMA channel can be shared by multiple vrings at the same time. From DPDK22.07, Vhost enqueue and dequeue operation with\n-DSA driver is supported in both split and packed ring.\n+Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an\n+asynchronous way. DPDK Vhost with DSA acceleration supports M:N mapping between virtqueues and DSA WQs. Specifically,\n+one DSA WQ can be used by multiple virtqueues and one virtqueue can offload copies to multiple DSA WQs at the same time.\n+Vhost async enqueue and async dequeue operation is supported in both split and packed ring.\n \n This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with\n DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-user topology.\n-1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check.\n-2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test and payload check.\n-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.\n-the split ring mergeable path use indirect descriptor, the 2000,2000,2000,2000 chain packets will only occupy one ring.\n+1.Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check.\n+2.Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test and payload check.\n+3.Test indirect descriptor feature.

For PA mode, page by page mapping may\n+\texceed IOMMU's max capability, better to use 1G guest hugepage.\n+\t2.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. In this patch,\n+\twe enable asynchronous data path for vhostpmd. Asynchronous data path is enabled per tx/rx queue, and users need to specify\n+\tthe DMA device used by the tx/rx queue. Each tx/rx queue only supports to use one DMA device (This is limited by the\n+\timplementation of vhostpmd), but one DMA device can be shared among multiple tx/rx queues of different vhost PMD ports.\n \n-Note:\n-1.When DMA devices are bound to vfio driver, VA mode is the default and recommended.
