+vm2vm vhost-user/virtio-user test plan
+=================================================
+
+Description
+===========
+Test indirect descriptor feature.
+For example, the split ring mergeable inorder path use non-indirect descriptor,
+the 2000,2000,2000,2000 chain packets will need 4 consequent ring, still need one ring put header.
+the split ring mergeable path use indirect descriptor,
+the 2000,2000,2000,2000 chain packets will only occupy one ring.
+
+This test plan test several features in VM2VM topo:
+1. Split ring and packed ring vm2vm test when vhost enqueue operation with multi-CBDMA channels.
+2. payload check
+3. iova=pa mode (When DMA devices are bound to vfio driver, VA mode is the default and recommended.
+For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.)
+
+For more about dpdk-testpmd sample, please refer to the DPDK docments:
+https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html
+
+For virtio-user vdev parameter, you can refer to the DPDK docments:
+https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.
+
+Prerequisites
+=============
+
+Topology
+--------
+Test flow: Virtio-user-->Vhost-user-->Testpmd-->Vhost-user-->Virtio-user
+
+Hardware
+--------
+Supportted NICs: ALL
+
+Software
+--------
+Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+
+General set up
+--------------
+1. Compile DPDK::
+
+ # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
+ # ninja -C <dpdk build dir> -j 110
+
+2. Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+ Network devices using kernel driver
+ ===================================
+ 0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+
+ DMA devices using kernel driver
+ ===============================
+ 0000:00:04.0 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci
+ 0000:00:04.1 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci
+
+Test case
+=========
+
+Common steps
+------------
+1. Bind 1 NIC port and CBDMA channels 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, 2 CBDMA channels::
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0,0000:00:04.1
+
+Test Case 1: split virtqueue vm2vm non-mergeable path multi-queues payload check with cbdma enable

+8. Rerun step 3-6.
+
+Test Case 14: packed virtqueue vm2vm vectorized-tx path test batch processing with cbdma enable
+-----------------------------------------------------------------------------------------------
+This case uses testpmd and 2 VMs to test of packed ring vectorized-tx path test batch processing with cbdma enable.
+
+1. Bind 8 CBDMA channel to vfio-pci, as common step 1.
+
+2. Launch vhost by below command::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 10-18 -n 4 \
+ -a 0000:00:04.0 -a 0000:00:04.1 -a 0000:00:04.2 -a 0000:00:04.3 -a 0000:00:04.4 -a 0000:00:04.5 -a 0000:00:04.6 -a 0000:00:04.7 \
+ --vdev 'eth_vhost0,iface=vhost-net,queues=1,client=1,dmas=[txq0],dma_ring_size=2048' \
+ --vdev 'eth_vhost1,iface=vhost-net1,queues=1,client=1,dmas=[txq0],dma_ring_size=2048' \
+ --iova=va -- -i --nb-cores=1 --rxq=1 --txq=1 --txd=256 --rxd=256 --no-flush-rx \
+ --lcore-dma=[lcore11@0000:00:04.0,lcore11@0000:00:04.1,lcore11@0000:00:04.2,lcore11@0000:00:04.3,lcore11@0000:00:04.4,lcore11@0000:00:04.5,lcore11@0000:00:04.6,lcore11@0000:00:04.7]
+
+3. Launch virtio-user1 by below command::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 7-8 --no-pci --file-prefix=virtio1 --force-max-simd-bitwidth=512 \
+ --vdev=net_virtio_user1,mac=00:01:02:03:04:05,path=./vhost-net1,queues=1,server=1,packed_vq=1,mrg_rxbuf=1,in_order=1,vectorized=1,queue_size=256 \
+ -- -i --nb-cores=1 --rxq=1 --txq=1 --txd=256 --rxd=256
+ testpmd>set fwd rxonly
+ testpmd>start
+
+4. Attach pdump secondary process to primary process by same file-prefix::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-pdump -v --file-prefix=virtio1 -- --pdump 'device_id=net_virtio_user1,queue=*,rx-dev=./pdump-virtio-rx.pcap,mbuf-size=8000'
+
+5. Launch virtio-user0 and send 1 packet::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 5-6 --force-max-simd-bitwidth=512 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=1,server=1,packed_vq=1,mrg_rxbuf=1,in_order=1,vectorized=1,queue_size=256 \
+ -- -i --nb-cores=1 --rxq=1 --txq=1 --txd=256 --rxd=256
+ testpmd>set burst 1
+ testpmd>start tx_first 1
+ testpmd>stop
+
+6. Start vhost, then quit pdump and three testpmd, check 1 packet and 64 bytes received by virtio-user1 and 1 packet with 64 length in pdump-virtio-rx.pcap.
