+vhost async data-path robust with cbdma test plan
+=================================================
+
+Description
+===========
+
+This document provides the test plan for testing Vhost asynchronous
+data path robust with CBDMA driver.
+
+CBDMA is a kind of DMA engine, Vhost asynchronous data path leverages DMA devices
+to offload memory copies from the CPU and it is implemented in an asynchronous way.
+As a result, large packet copy can be accelerated by the DMA engine, and vhost can
+free CPU cycles for higher level functions.
+
+Asynchronous data path is enabled per tx/rx queue, and users need
+to specify the DMA device used by the tx/rx queue. Each tx/rx queue
+only supports to use one DMA device, but one DMA device can be shared
+among multiple tx/rx queues of different vhostpmd ports.
+
+Two PMD parameters are added:
+- dmas: specify the used DMA device for a tx/rx queue
+(Default: no queues enable asynchronous data path)
+- dma-ring-size: DMA ring size.
+(Default: 4096).
+
+Here is an example:
+--vdev 'eth_vhost0,iface=./s0,dmas=[txq0@0000:00.01.0;rxq0@0000:00.01.1],dma-ring-size=4096'
+
+Test case
+=========
+
+Common steps
+------------
+1. Bind 1 NIC port and CBDMA devices to vfio-pci::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DMA device id>
+
+ For example, Bind 1 NIC port and 2 CBDMA devices::
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:18.0
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0,0000:00:04.1
+
+2. Send imix packets [64,1518] to NIC by traffic generator::
+
+ The TCP imix packets include packet size [64, 128, 256, 512, 1024, 1518], and the format of packet is as follows.
+ +-------------+-------------+-------------+-------------+
+ | MAC | MAC | IPV4 | IPV4 |
+ | Src address | Dst address | Src address | Dst address |
+ |-------------|-------------|-------------|-------------|
+ | Random MAC | Virtio mac | Random IP | Random IP |
+ +-------------+-------------+-------------+-------------+
+ All the packets in this test plan use the Virtio mac: 00:11:22:33:44:10.
+
+Test Case 1: PVP virtio-user quit test
+--------------------------------------
+This case is designed to test if virtio-user can quit normally regardless of whether the back-end stop sending packets.
+
+1. Bind 1 NIC port and 1 CBDMA devices to vfio-pci as common step 1.
+
+2. Launch vhost by below command::
+
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 10-18 --file-prefix=vhost \
+ -a 0000:18:00.1 -a 0000:00:04.0 \
+ --vdev 'net_vhost0,iface=./vhost_net0,queues=1,dmas=[txq0@0000:00:04.0;rxq0@0000:00:04.0]' \
+ --iova=va -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=1024 --rxd=1024
+ testpmd> set fwd mac
+ testpmd> start
+
+3. Launch virtio-user with inorder mergeable path::
+
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 2-6 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=./vhost_net0,mrg_rxbuf=1,in_order=1,queues=1 \
+ -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=1024 --rxd=1024
+ testpmd> set fwd csum
+ testpmd> start
+
+4. Send TCP imix packets [64,1518] from packet generator as common step2.
+
+5. Quit virtio-user and relaunch virtio-user as step 3 while sending packets from packet generator.
+
+6. Stop vhost port, then quit virtio-user and reluanch virtio-user as step 3 while sending packets from packet generator.
+
+7. Stop sending packets from packet generator, then quit virtio-user and vhost.
+
+Test Case 2: PVP vhost-user quit test
+-------------------------------------
+This case is designed to test if vhost-user can quit normally regardless of whether the back-end stop sending packets.

+
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 10-18 --file-prefix=vhost \
+ -a 0000:18:00.1 -a 0000:00:04.0 \
+ --vdev 'net_vhost0,iface=./vhost_net0,queues=1,client=1,dmas=[txq0@0000:00:04.0;rxq0@0000:00:04.0]' \
+ --iova=va -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=1024 --rxd=1024
+ testpmd> set fwd mac
+ testpmd> start
+
+3. Launch virtio-user with inorder mergeable path::
+
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 2-6 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=./vhost_net0,mrg_rxbuf=1,in_order=1,queues=1,server=1 \
+ -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=1024 --rxd=1024

+
+4. Send TCP imix packets [64,1518] from packet generator as common step2.
+
+5. Quit vhost-user and relaunch vhost-user as step 2 while sending packets from packet generator.
+
+6. Stop sending packets from packet generator, then quit vhost-user and virtio-user.

+Test Case 3: PVP vhost async test with redundant device parameters
+------------------------------------------------------------------
+This case is designed to test if vhostpmd can work normally when binding and using redundant device parameters.
+
+1. Bind 1 NIC port and 4 CBDMA devices to vfio-pci as common step 1.
+
+2. Launch vhost by below command::
+
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 10-18 --file-prefix=vhost \
+ -a 0000:18:00.1 -a 0000:00:04.0 -a 0000:00:04.1 -a 0000:00:04.2 -a 0000:00:04.3 \
+ --vdev 'net_vhost0,iface=./vhost_net0,queues=1,client=1,dmas=[txq0@0000:00:04.1;rxq0@0000:00:04.1]' \
+ --iova=va -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=1024 --rxd=1024

+ testpmd> set fwd csum
+ testpmd> start
+
+4. Send imix packets [64,1518] from packet generator as common step2, check the throughput.
+
+Test Case 4: Loopback vhost async test with each queue using 2 DMA devices

+
+2. Launch vhost by below command::
+

+Test Case 6: VM2VM split and packed ring mergeable path with cbdma enable and server mode
+-----------------------------------------------------------------------------------------
+This case tests split and packed ring with cbdma can work normally when the front-end change from virtio-net to virtio-pmd.
+
+1. Bind 16 CBDMA channels to vfio-pci, as common step 1.
+
+2. Launch the testpmd with 2 vhost ports below commands::
