-This document provides the test plan for testing some basic functions with DSA driver(kernel IDXD driver and DPDK vfio-pci driver)
+This document provides the test plan for testing some basic functions with DSA driver(kernel IDXD driver and DPDK vfio-pci driver)
in vm2vm vhost-user/virtio-pmd topology environment.
1. vm2vm mergeable, non-mergebale path test with virtio 1.0 and virtio1.1 and check virtio-pmd tx chain packets in mergeable path.
2. dynamic change queue number.
-..Note:
-1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet.
-2.For split virtqueue virtio-net with multi-queues server mode test, better to use qemu version >= 5.2.0, dut to qemu(v4.2.0~v5.1.0) exist split ring multi-queues reconnection issue.
-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.
+.. note::
-For more about dpdk-testpmd sample, please refer to the DPDK docments:

+ 4.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.
