+vhost/virtio-pmd interrupt mode with cbdma test plan
+====================================================
+
+Description
+===========
+
+Virtio-pmd interrupt need test with l3fwd-power sample, small packets send from traffic generator
+to virtio-pmd side,check virtio-pmd cores can be wakeup status,and virtio-pmd cores should be
+sleep status after stop sending packets from traffic generator when cbdma enabled.This test plan 
+cover virtio 0.95, virtio 1.0 and virtio 1.1.
+
+..Note:
+1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet.
+2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version >= 5.2.0, dut to old qemu exist reconnect issue when multi-queues test.
+3.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.
+
+Prerequisites
+=============
+
+Test ENV preparation: Kernel version > 4.8.0, mostly linux distribution don't support vfio-noiommu mode by default,
+so testing this case need rebuild kernel to enable vfio-noiommu.
+
+Test flow
+=========
+
+TG --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> TG
+
+Test Case1: Basic virtio interrupt test with 16 queues and cbdma enabled
+=========================================================================
+
+1. Bind 16 cbdma channels and one NIC port to vfio-pci, then launch testpmd by below command::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x1ffff -n 4 \
+    --vdev 'eth_vhost0,iface=vhost-net,queues=16,dmas=[txq0@80:04.0;txq1@80:04.1;txq2@80:04.2;txq3@80:04.3;txq4@80:04.4;txq5@80:04.5;txq6@80:04.6;txq7@80:04.7;txq8@00:04.0;txq9@00:04.1;txq10@00:04.2;txq11@00:04.3;txq12@00:04.4;txq13@00:04.5;txq14@00:04.6;txq15@00:04.7]' \
+    -- -i --nb-cores=16 --rxq=16 --txq=16 --rss-ip
+
+2. Launch VM1, set queues=16, vectors>=2xqueues+2, mq=on::
+
+    taskset -c 34-35 \
+    qemu-system-x86_64 -name us-vhost-vm2 \
+     -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/ubuntu1910.img \
+     -monitor unix:/tmp/vm2_monitor.sock,server,nowait -device e1000,netdev=nttsip1 \
+     -netdev user,id=nttsip1,hostfwd=tcp:127.0.0.1:6003-:22 \
+     -chardev socket,id=char1,path=./vhost-net -netdev type=vhost-user,id=mynet2,chardev=char1,vhostforce,queues=16 \
+     -device virtio-net-pci,mac=52:54:00:00:00:02,netdev=mynet2,mrg_rxbuf=on,csum=on,mq=on,vectors=40  \
+     -vnc :11 -daemonize
+
+3. Bind virtio port to vfio-pci::
+
+    modprobe vfio enable_unsafe_noiommu_mode=1
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py --bind=vfio-pci xx:xx.x
+
+4. In VM, launch l3fwd-power sample::
+
+    ./x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power -c 0x0ffff -n 4 --log-level='user1,7' \
+    -- -p 1 -P  --config '(0,0,0),(0,1,1),(0,2,2),(0,3,3)(0,4,4),(0,5,5),(0,6,6),(0,7,7)(0,8,8),(0,9,9),(0,10,10),(0,11,11)(0,12,12),(0,13,13),(0,14,14),(0,15,15)' \
+    --no-numa  --parse-ptype
+
+5. Send random dest ip address packets to host nic with packet generator, packets will distribute to all queues, check l3fwd-power log that all related cores are waked up.
+
+6. Change dest IP address to fixed ip, packets will distribute to 1 queue, check l3fwd-power log that only one related core is waked up.
+
+7. Stop the date transmitter, check all related core will be back to sleep status.
+
