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

202.1. 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.

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

1. Enable the shared lib in DPDK configure file:

   vi ./config/common_base
   -CONFIG_RTE_BUILD_SHARED_LIB=n
   +CONFIG_RTE_BUILD_SHARED_LIB=y
   

2. Recompile dpdk code:

   make install T=x86_64-native-linux-gcc -j 30
   

3. Export shared lib files into host environment:

   export LD_LIBRARY_PATH=/root/dpdk/x86_64-native-linuxapp-gcc/lib:$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_pmd_vhost.so.2.1 -d librte_pmd_ixgbe.so.2.1 -d librte_mempool_ring.so.1.1 \
   --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_pmd_virtio.so.1.1 -d librte_mempool_ring.so.1.1 \
   --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
   

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

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

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

   ./testpmd  -c 0x03 -n 4 -d librte_pmd_vhost.so.2.1 -d librte_pmd_i40e.so.1.1 -d librte_mempool_ring.so.1.1 \
   --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i
   testpmd>start
