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

244.1. 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.

244.2. Test Case 1: Vhost/virtio-user pvp share lib test with Intel® Ethernet 82599 Series

  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 82599 port with vfio-pci, use option -d to load the dynamic pmd when launch vhost:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -c 0x03 -n 4 -d librte_net_vhost.so -d librte_net_ixgbe.so -d librte_mempool_ring.so \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i
testpmd>start

  5. Launch virtio-user:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x0c -n 4 -d librte_net_virtio.so -d librte_mempool_ring.so \
--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

244.3. Test Case 2: Vhost/virtio-user pvp share lib test with Intel® Ethernet 700 Series

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

  1. Bind Intel® Ethernet 700 Series port with vfio-pci, use option -d to load the dynamic pmd when launch vhost:

    ./x86_64-native-linuxapp-gcc/app/dpdk-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

244.4. Test Case 3: Vhost/virtio-user pvp share lib test with Intel® Ethernet 800 Series

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

  1. Bind Intel® Ethernet 800 Series port with vfio-pci, use option -d to load the dynamic pmd when launch vhost:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -c 0x03 -n 4 -d librte_net_vhost.so -d librte_net_ice.so -d librte_mempool_ring.so \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i
testpmd>start
