 Loopback vhost-user/virtio-user server mode with DSA driver test plan
-=======================================================================
+=====================================================================
 
 Description
 ===========
 
-Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.
-In addition, vhost supports M:N mapping between vrings and DMA virtual channels. 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 and dequeue operation with CBDMA channels is supported
-in both split and packed ring.
+Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an
+asynchronous way. DPDK Vhost with DSA acceleration supports M:N mapping between virtqueues and DSA WQs. Specifically,
+one DSA WQ can be used by multiple virtqueues and one virtqueue can offload copies to multiple DSA WQs at the same time.
+Vhost async enqueue and async dequeue operation 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. In this patch,
+	we enable asynchronous data path for vhostpmd. Asynchronous data path is enabled per tx/rx queue, and users need to specify
+	the DMA device used by the tx/rx queue. Each tx/rx queue only supports to use one DMA device (This is limited by the
+	implementation of vhostpmd), but one DMA device can be shared among multiple tx/rx queues of different vhost PMD ports.
 
-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

-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.
+Two PMD parameters are added:
+- dmas:	specify the used DMA device for a tx/rx queue.(Default: no queues enable asynchronous data path)
+- dma-ring-size: DMA ring size.(Default: 4096).
+
+Here is an example:
+--vdev 'eth_vhost0,iface=./s0,dmas=[txq0@0000:00.01.0;rxq0@0000:00.01.1],dma-ring-size=2048'
