+VM2VM vhost-user/virtio-user with CBDMA test plan
+==================================================
+
+Description
+===========
+
+Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.
+In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA
+channels and one DMA channel can be shared by multiple vrings at the same time.Vhost enqueue operation with CBDMA channels is supported
+in both split and packed ring.
+
+This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with
+CBDMA channels in VM2VM virtio-user topology.
+1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check.
+2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test and payload check.
+3. 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.
+
+Note:
+1.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.
+2.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.
+
+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
+
+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
+      For example:
+      CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=x86_64-native-linuxapp-gcc
+      ninja -C x86_64-native-linuxapp-gcc -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:
+      <dpdk dir># ./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
+--------------------------------------------------------------------------------------------------
+This case uses testpmd to test the payload is valid after packets forwarding in vhost-user/virtio-user split ring non-mergeable path 
+and multi-queues when vhost uses the asynchronous enqueue operations with CBDMA channels. Both iova as VA and PA mode test.
+
+1. Bind 2 CBDMA channel to vfio-pci, as common step 1.
+

+    testpmd>start tx_first 7
+    testpmd>stop
+    testpmd>set burst 1
+    testpmd>set txpkts 64,256,2000,64,256,2000
+    testpmd>start tx_first 27
+    testpmd>stop
+
+6. Start vhost testpmd, then quit pdump, check 448 packets and 28672 bytes received by virtio-user1 and 448 packets with 64 length in pdump-virtio-rx.pcap.
+
+7. Quit vhost testpmd::
+
+    testpmd>quit
+
+8. Clear virtio-user1 port stats, execute below command::
+
+    testpmd>stop
+    testpmd>clear port stats all
+    testpmd>start
+
+9. Relaunch vhost with iova=pa by below command::
+
+    <dpdk dir># ./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=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --vdev 'eth_vhost1,iface=vhost-net1,queues=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --iova=pa -- -i --nb-cores=1 --rxq=2 --txq=2 --txd=4096 --rxd=4096 --no-flush-rx \
+    --lcore-dma=[lcore11@0000:00:04.0,lcore11@0000:00:04.1,lcore11@0000:00:04.2,lcore12@0000:00:04.3,lcore12@0000:00:04.4,lcore12@0000:00:04.5,lcore12@0000:00:04.6,lcore12@0000:00:04.7]
+
+10. Rerun step 4.
+
+11. Virtio-user0 send packets::
+
+	testpmd>set burst 32
+	testpmd>set txpkts 64
+	testpmd>start tx_first 7
+	testpmd>stop
+	testpmd>set burst 1
+	testpmd>set txpkts 64,256,2000,64,256,2000
+	testpmd>start tx_first 27
+	testpmd>stop
+
+12. Rerun step 6.
+
+Test Case 13: packed virtqueue vm2vm vectorized-tx path multi-queues test indirect descriptor with cbdma enable
+---------------------------------------------------------------------------------------------------------------
+This case uses testpmd to test the payload is valid and indirect descriptor after packets forwarding in vhost-user/virtio-user
+packed ring vectorized-tx path and multi-queues when vhost uses the asynchronous enqueue operations with CBDMA channels.
+Both iova as VA and PA mode test.
+
+1. Bind 8 CBDMA channel to vfio-pci, as common step 1.
+
+2. Launch vhost by below command::
+
+    <dpdk dir># ./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=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --vdev 'eth_vhost1,iface=vhost-net1,queues=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --iova=va -- -i --nb-cores=1 --rxq=2 --txq=2 --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::
+
+    <dpdk dir># ./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=2,server=1,packed_vq=1,mrg_rxbuf=1,in_order=1,vectorized=1,queue_size=256 \
+    -- -i --nb-cores=1 --rxq=2 --txq=2 --txd=256 --rxd=256
+    testpmd>set fwd rxonly
+    testpmd>start
+
+4. Attach pdump secondary process to primary process of virtio-user1 by same file-prefix::
+
+    <dpdk dir># ./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 8k length packets::
+
+    <dpdk dir># ./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=2,server=1,packed_vq=1,mrg_rxbuf=1,in_order=1,vectorized=1,queue_size=256 \
+    -- -i --nb-cores=1 --rxq=2 --txq=2 --txd=256 --rxd=256
+
+    testpmd>set burst 1
+    testpmd>start tx_first 27
+    testpmd>stop
+    testpmd>set burst 32
+    testpmd>start tx_first 7
+    testpmd>stop
+    testpmd>set txpkts 2000,2000,2000,2000
+    testpmd>start tx_first 1
+    testpmd>stop
+
+6. Start vhost, then quit pdump and three testpmd, about packed virtqueue vectorized-tx path, it use the indirect descriptors, the 8k length pkt will just occupies one ring.
+So check 512 packets and 112128 bytes received by virtio-user1 and 502 packets with 64 length and 10 packets with 8K length in pdump-virtio-rx.pcap.
+
+7. Relaunch vhost with iova=pa by below command::
+
+    <dpdk dir># ./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=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --vdev 'eth_vhost1,iface=vhost-net1,queues=2,client=1,dmas=[txq0;txq1],dma_ring_size=2048' \
+    --iova=pa -- -i --nb-cores=1 --rxq=2 --txq=2 --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]
+
+8. Rerun step 3-6.
+
+Test Case 14: packed virtqueue vm2vm vectorized-tx path test batch processing with cbdma enable
+-----------------------------------------------------------------------------------------------
+This case uses testpmd to test that one packet can forwarding in vhost-user/virtio-user packed ring vectorized-tx path 
+when vhost uses the asynchronous enqueue operations with CBDMA channels.
+
+1. Bind 8 CBDMA channel to vfio-pci, as common step 1.
+
+2. Launch vhost by below command::
+
+    <dpdk dir># ./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]
+

+    --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 of virtio-user1 by same file-prefix::
+
+    <dpdk dir># ./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::
