113. vhost/virtio-user pvp with multi-queues and port restart test plan¶

113.1. Description¶

This test plan test vhost/virtio-user pvp multi-queues with split virtqueue and packed virtqueue different rx/tx paths, includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable and vectorized path, also cover port restart test with each path.

113.2. Test flow¶

TG –> NIC –> Vhost –> Virtio–> Vhost –> NIC –> TG

113.3. Test Case 1: pvp 2 queues test with packed ring mergeable path¶

Bind one port to vfio-pci, then launch vhost by below command:

rm -rf vhost-net*
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 2-4  \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=2,client=0' -- -i --nb-cores=2 --rxq=2 --txq=2
testpmd>set fwd mac
testpmd>start

Launch virtio-user by below command:

./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 5-7 \
