+ 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.
-For more about dpdk-testpmd sample, please refer to the DPDK docments:
-https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html
-For virtio-user vdev parameter, you can refer to the DPDK docments:
-https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.
+ 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'

Test Case 8: vm2vm vhost/virtio-net split packed ring multi queues with 1G/4k-pages and cbdma enable

-This case uses iperf and scp to test the payload of large packet (larger than 1MB) is valid after packets forwarding in vm2vm vhost-user/virtio-net
-split and packed ring mergeable path when vhost uses the asynchronous operations with CBDMA channels,the back-end is in 1G-pages memory environment and the front-end is in 4k-pages memory environment.

3. On VM1, set virtio device IP and run arp protocal::
- ethtool -L ens5 combined 8
- ifconfig ens5 1.1.1.2
- arp -s 1.1.1.8 52:54:00:00:00:02
+ ethtool -L ens5 combined 8
+ ifconfig ens5 1.1.1.2
+ arp -s 1.1.1.8 52:54:00:00:00:02

- ethtool -L ens5 combined 8
- ifconfig ens5 1.1.1.8
- arp -s 1.1.1.2 52:54:00:00:00:01
+ ethtool -L ens5 combined 8
+ ifconfig ens5 1.1.1.8
+ arp -s 1.1.1.2 52:54:00:00:00:01
5. Scp 1MB file form VM1 to VM2::
- Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
+ Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
6. Check the iperf performance between two VMs by below commands::
- Under VM1, run: `iperf -s -i 1`
- Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
+ Under VM1, run: `iperf -s -i 1`
+ Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
7. Relaunch VM1, and rerun step 3.
