142. vhost event idx interrupt mode test plan

142.1. Description

Vhost event idx interrupt need test with l3fwd-power sample, send small packets from virtio-net to vhost side，check vhost-user cores can be wakeup status，and vhost-user cores should be sleep status after stop sending packets from virtio side.For packed virtqueue test, need using qemu version > 4.2.0.

142.2. Test flow

Virtio-net –> Vhost-user

142.3. Test Case 1: wake up split ring vhost-user core with event idx interrupt mode

  1. Launch l3fwd-power example app with client mode:

    ./l3fwd-power -l 1 \
-n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
--log-level=9 \
--vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1' \
-- -p 0x1 \
--parse-ptype 1 \
--config "(0,0,1)"

  2. Launch VM1 with server mode:

    taskset -c 33 \
qemu-system-x86_64 -name us-vhost-vm1 \
-cpu host -enable-kvm -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,vlan=2,macaddr=00:00:00:08:e8:aa,addr=1f -net user,vlan=2,hostfwd=tcp:127.0.0.1:6001-:22 \

-device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,csum=on -vnc :10 -daemonize

--log-level=9 \
--vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1' \
-- -p 0x1 \
--parse-ptype 1 \
--config "(0,0,1)"

  4. On VM, set ip for virtio device and send packets to vhost by cmds:

    ifconfig [ens3] 1.1.1.2
#[ens3] is the virtual device name
ping 1.1.1.3
#send packets to vhost

  5. Check vhost related core is waked up by reading l3fwd-power log.
