167. vhost/virtio-user loopback with multi-queues test plan

This test plan test loopback multi-queues with split virtqueue mergeable, non-mergeable, vectorized_rx, inorder mergeable, inorder non-mergeable path, and packed virtqueue mergeable, non-mergeable，inorder mergeable, inorder non-mergeable, vectorized path. And virtio-user support 8 queues in maximum, check performance could be linear growth when enable 8 queues and 8 cores, notice cores should in same socket.

167.1. Test Case 1: loopback with virtio 1.1 mergeable path using 1 queue and 8 queues

   testpmd>quit
   

6. Launch testpmd by below command:

   rm -rf vhost-net*
   ./<build_target>/app/dpdk-testpmd -l 1-9 -n 4 --no-pci --vdev 'eth_vhost0,iface=vhost-net,queues=8' -- \
   -i --nb-cores=8 --rxq=8 --txq=8 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   

7. Launch virtio-user by below command:

   ./<build_target>/app/dpdk-testpmd -n 4 -l 10-18 \
   --no-pci --file-prefix=virtio \
   --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=8,packed_vq=1,mrg_rxbuf=0,in_order=1,vectorized=1 \
   -- -i --rx-offloads=0x10 --nb-cores=8 --rxq=8 --txq=8 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   testpmd>start
   

8. Send packets with vhost-testpmd,[frame_size] is the parameter changs in [64, 128, 256, 512, 1024, 1518]:

   testpmd>set txpkts [frame_size]
   testpmd>start tx_first 32
   

9. Get throughput 10 times and calculate the average throughput，check the throughput of 8 queues is eight times of 1 queue:

   testpmd>show port stats all
   

167.10. Test Case 10: loopback with virtio 1.1 vectorized path using 1 queue and 8 queues

1. Launch testpmd by below command:

   -i --nb-cores=1 --txd=1024 --rxd=1024
   testpmd>set fwd mac
   

2. Launch virtio-user by below command:
