Commit Message

Ling, WeiX Nov. 11, 2022, 8:15 a.m. UTC 
  1.From DPDK-22.11, the dmas parameter have changed from
`lcore-dma=[lcore1@0000:00:04.0]` to `dmas=[txq0@0000:00:04.0]` by DPDK
local patch,so modify the dmas parameter.
2.Add some new testcase to cover the 2 type DSA driver, include DPDK
driver and kernel driver.

 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.
+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, but one DMA device can be shared among multiple tx/rx queues of different vhostpmd ports.
+
+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:
