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. From DPDK22.07, Vhost enqueue and dequeue operation with
-DSA driver 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 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.

+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. 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.

-2.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.
+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'
