206. Vhost/virtio-user pvp share lib test plan

206.1. Description

The feature need compile dpdk as shared libraries, then application should use option -d to load the dynamic pmd that are built as shared libraries.

206.2. Test Case1: Vhost/virtio-user pvp share lib test with niantic

  1. Enable the shared lib in DPDK configure file:

    CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dc_args='-DRTE_BUILD_SHARED_LIB=1' --default-library=shared x86_64-native-linuxapp-gcc
    
  2. Recompile dpdk code:

    ninja -C x86_64-native-linuxapp-gcc -j 55
    
  3. Export shared lib files into host environment:

    export LD_LIBRARY_PATH=/root/dpdk/x86_64-native-linuxapp-gcc/drivers:$LD_LIBRARY_PATH
    
  4. Bind niantic port with igb_uio, use option -d to load the dynamic pmd when launch vhost:

    ./testpmd  -c 0x03 -n 4 -d librte_net_vhost.so.21.0 -d librte_net_i40e.so.21.0 -d librte_mempool_ring.so.21.0 \
    --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i
    testpmd>start
    
  5. Launch virtio-user:

    ./testpmd -c 0x0c -n 4 -d librte_net_virtio.so.21.0 -d librte_mempool_ring.so.21.0 \
    --no-pci --file-prefix=virtio  --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net -- -i
    testpmd>start
    
  6. Send traffic by packet generator, check the throughput with below command:

    testpmd>show port stats all
    

206.3. Test Case2: Vhost/virtio-user pvp share lib test with fortville

Similar as Test Case1, all steps are similar except step 4:

  1. Bind fortville port with igb_uio, use option -d to load the dynamic pmd when launch vhost:

    ./testpmd  -c 0x03 -n 4 -d librte_net_vhost.so -d librte_net_i40e.so -d librte_mempool_ring.so \
    --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i
    testpmd>start
