214. Vhost/virtio-user pvp share lib test plan¶
214.1. 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.
214.2. Test Case1: Vhost/virtio-user pvp share lib test with niantic¶
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
Recompile dpdk code:
ninja -C x86_64-native-linuxapp-gcc -j 55
Export shared lib files into host environment:
export LD_LIBRARY_PATH=/root/dpdk/x86_64-native-linuxapp-gcc/drivers:$LD_LIBRARY_PATH
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
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
Send traffic by packet generator, check the throughput with below command:
testpmd>show port stats all
214.3. Test Case2: Vhost/virtio-user pvp share lib test with fortville¶
Similar as Test Case1, all steps are similar except step 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_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
