Specifically, one vring can use multiple different DMA\r\n+channels and one DMA channel can be shared by multiple vrings at the same time.Vhost enqueue operation with CBDMA channels is supported\r\n+in both split and packed ring.\r\n+\r\n+This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with\r\n+DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-user topology.\r\n+1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check.\r\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.\r\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.\r\n+the split ring mergeable path use indirect descriptor, the 2000,2000,2000,2000 chain packets will only occupy one ring.\r\n+\r\n+IOMMU impact:\r\n+If iommu off, idxd can work with iova=pa\r\n+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).\r\n+\r\n+Note:\r\n+1.When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may\r\n+exceed IOMMU's max capability, better to use 1G guest hugepage.\r\n+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.\r\n+\r\n+Prerequisites\r\n+=============\r\n+\r\n+Topology\r\n+--------\r\n+\tTest flow: Virtio-user -> Vhost-user -> Testpmd -> Vhost-user -> Virtio-user\r\n+\r\n+General set up\r\n+--------------\r\n+1.
