+virtio event idx interrupt mode test plan
+=========================================
+
+Description
+===========
+
+This feature is to suppress interrupts for performance improvement, need compare interrupt times with and without
+virtio event idx enabled. Also need cover driver reload and live migration test.
+
+Test flow
+=========
+
+TG --> NIC --> Vhost-user --> Virtio-net
+
+Test Case 1: compare interrupt times with and without virtio event idx enabled
+==============================================================================
+
+1. Bind one nic port to igb_uio, then launch the vhost sample by below commands::
+
+ rm -rf vhost-net*
+ ./testpmd -c 0xF0000000 -n 4 --socket-mem 2048,2048 --legacy-mem --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,queues=1' -- -i
+ --nb-cores=1 --txd=1024 --rxd=1024
+ testpmd>start
+
+2. Launch VM::
+
+ taskset -c 32-33 \
+ 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 \
+ -smp cores=2,sockets=1 -drive file=/home/osimg/ubuntu16.img \
+ -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:127.0.0.1:6004-:22 \
+ -chardev socket,id=char0,path=./vhost-net -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,csum=on,gso=on,guest_csum=on,host_tso4=on,guest_tso4=on,guest_ecn=on \
+ -vnc :12 -daemonize
+
+3. On VM1, set virtio device IP::
+
+ ifconfig [ens3] 1.1.1.2 # [ens3] is the name of virtio-net
+
+4. Send 10M packets from packet generator to nic, check virtio-net interrupt times by below cmd in VM::
+
+ cat /proc/interrupts
+
+5. Disable virtio event idx feature and rerun step1 ~ step4.
+
+6. Compare interrupt times between virtio event_idx enabled and virtio event_idx disabled.
+
+Test Case 2: virtio-pci driver reload test
+==========================================
+
+1. Bind one nic port to igb_uio, then launch the vhost sample by below commands::
+
+ rm -rf vhost-net*
+ ./testpmd -c 0xF0000000 -n 4 --socket-mem 2048,2048 --legacy-mem --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,queues=1' -- -i --nb-cores=1 --txd=1024 --rxd=1024
+ testpmd>start
+
+2. Launch VM::
+
+ taskset -c 32-33 \
+ 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 \
+ -smp cores=2,sockets=1 -drive file=/home/osimg/ubuntu16.img \
+ -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:127.0.0.1:6004-:22 \
+ -chardev socket,id=char0,path=./vhost-net -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,csum=on,gso=on,guest_csum=on,host_tso4=on,guest_tso4=on,guest_ecn=on \
+ -vnc :12 -daemonize
+
+3. On VM1, set virtio device IP, send 10M packets from packet generator to nic then check virtio device can receive packets::
+
+ ifconfig [ens3] 1.1.1.2 # [ens3] is the name of virtio-net
+ tcpdump -i [ens3]
+
+4. Reload virtio-net driver by below cmds::
+
+ ifconfig [ens3] down
+ ./dpdk-devbind.py -u [00:03.0] # [00:03.0] is the pci addr of virtio-net
+ ./dpdk-devbind.py -b virtio-pci [00:03.0]
+
+5. Check virtio device can receive packets again::
+
+ ifconfig [ens3] 1.1.1.2
+ tcpdump -i [ens3]
+
+6. Rerun step4 and step5 100 times to check event idx workable after driver reload.
+
+Test Case 3: wake up virtio-net cores with event idx interrupt mode 16 queues test
+==================================================================================
+
+1. Bind one nic port to igb_uio, then launch the vhost sample by below commands::
+
+ rm -rf vhost-net*
+ ./testpmd -l 1-17 -n 4 --socket-mem 2048,2048 --legacy-mem --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,queues=16' -- -i --nb-cores=16 --txd=1024 --rxd=1024 --rxq=16 --txq=16
+ testpmd>start
+
+2. Launch VM::
+
+ taskset -c 32-33 \
+ 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 \
+ -smp cores=16,sockets=1 -drive file=/home/osimg/ubuntu16.img \
+ -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:127.0.0.1:6004-:22 \
+ -chardev socket,id=char0,path=./vhost-net -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=16 \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,mq=on,vectors=40,csum=on,gso=on,guest_csum=on,host_tso4=on,guest_tso4=on,guest_ecn=on \
+ -vnc :12 -daemonize
+
+3. On VM1, give virtio device ip addr and enable vitio-net with 16 quques::
+
+ ifconfig [ens3] 1.1.1.2 # [ens3] is the name of virtio-net
+ ethtool -L [ens3] combined 16
+
+4. Send 10M different ip addr packets from packet generator to nic, check virtio-net interrupt times by below cmd in VM::
+
+ cat /proc/interrupts
+
+5. After two hours stress test, stop and restart testpmd, check each queue has new packets coming::
+
+ testpmd>stop
+ testpmd>start
+ testpmd>stop
