+Vswitch sample test vhost async operation with DSA driver test plan
+====================================================================
+
+Vswitch sample can leverage DMA to accelerate vhost async data-path from dpdk 20.11. This plan test
+vhost async operation with dsa driver (kernel IDXD driver and DPDK vfio-pci driver) in vhost sample.
+For more about vswitch example, please refer to the DPDK docment:http://doc.dpdk.org/guides/sample_app_ug/vhost.html
+
+Note:
+1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1, 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.The suite has not yet been automated.
+
+Prerequisites
+=============
+
+Software
+--------
+Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+qemu: https://download.qemu.org/qemu-6.2.0.tar.xz
+iperf
+
+General set up
+--------------
+1. Compile DPDK and vhost example::
+
+	# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
+	# meson configure -Dexamples=vhost <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 DSA device ID of DUT, for example, 0000:4f:00.1 is PCI device ID, 0000:6a:01.0 - 0000:f6:01.0 are DSA device IDs::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -s
+
+	Network devices using kernel driver
+	===================================
+	0000:4f:00.1 'Ethernet Controller E810-C for QSFP 1592' drv=ice unused=vfio-pci
+
+	DMA devices using kernel driver
+	===============================
+	0000:6a:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:6f:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:74:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:79:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:e7:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:ec:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:f1:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+	0000:f6:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+
+Test case
+=========
+
+Common steps
+------------
+1. Bind 1 NIC port to vfio-pci::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
+	For example:
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:4f.1
+
+2.Bind DSA devices to DPDK vfio-pci driver::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DSA device id>
+	For example, bind 2 DMA devices to vfio-pci driver:
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:e7:01.0 0000:ec:01.0
+
+.. note::
+
+	One DPDK DSA device can create 8 WQ at most. Below is an example, where DPDK DSA device will create one and
+	eight WQ for DSA deivce 0000:e7:01.0 and 0000:ec:01.0. The value of “max_queues” is 1~8:
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:e7:01.0,max_queues=1 -- -i
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:ec:01.0,max_queues=8 -- -i
+
+3. Bind DSA devices to kernel idxd driver, and configure Work Queue (WQ)::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd <numDevices * 2>
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q <numWq>
+
+.. note::
+
+	Better to reset WQ when need operate DSA devices that bound to idxd drvier:
+	<dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py --reset <numDevices * 2>
+	You can check it by 'ls /dev/dsa'
+	numDevices: number of devices, where 0<=numDevices<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0
+	numWq: Number of workqueues per DSA endpoint, where 1<=numWq<=8
+
+	For example, bind 2 DMA devices to idxd driver and configure WQ:
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 2
+	Check WQ by 'ls /dev/dsa' and can find "wq0.0 wq2.0 wq2.1 wq2.2 wq2.3"
+
+Test Case 1: PVP performance vhost async enqueue operation with dsa dpdk channel
+---------------------------------------------------------------------------------
+This case uses vhost example to test performance of split and packed ring when vhost uses the asynchronous enqueue operations 
+with dsa dpdk driver in PVP topology environment.
+
+1. Bind one physical port(4f:00.1) and one dsa device(6a:01.0) to vfio-pci like common step 1-2.

+	<dpdk dir># ./<dpdk build dir>/examples/dpdk-vhost -l 2-3 -n 4 -a 0000:4f:00.0 -a 0000:6a:01.0,max_queues=1 -- \
+	-p 0x1 --mergeable 1 --vm2vm 1  --stats 1 --socket-file /tmp/vhost-net --dmas [txd0@0000:6a:01.0-q0] --client
+
+3. Launch virtio-user with packed ring::
+
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=virtio-user \
+	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,packed_vq=1,server=1 \
+	-- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1
+
+4. Start pkts from virtio-user side to let vswitch know the mac addr::
+
+	testpmd>set fwd mac
+	testpmd>start tx_first
+	testpmd>stop
+	testpmd>start
+
+5. Inject pkts (packets length=64...1518) separately with dest_mac=virtio_mac_addresss (specific in above cmd with 00:11:22:33:44:10) to NIC using packet generator, record pvp (PG>nic>vswitch>virtio-user>vswitch>nic>PG) performance number can get expected.
+
+6. Quit and re-launch virtio-user with packed ring size not power of 2::
+
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0  \
+	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,packed_vq=1,server=1,queue_size=1025 -- -i --rxq=1 --txq=1 --txd=1025 --rxd=1025 --nb-cores=1
+
+7. Re-test step 4-5, record performance of different packet length.
+
+8. Quit and re-launch virtio-user with split ring::
+
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0 \
+	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,server=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1
+
+9. Re-test step 4-5, record performance of different packet length.
+
+Test Case 2: PVP vhost async enqueue operation with two VM and 2 dsa channels

+	-p 0x1 --mergeable 1 --vm2vm 1  --stats 1 --socket-file /tmp/vhost-net0 --socket-file /tmp/vhost-net1 --dmas [txd0@0000:6a:01.0-q1,txd1@0000:6f:01.0-q0] --client
+
+3. launch two virtio-user ports::
+
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0 \
+	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net0,queues=1,server=1,mrg_rxbuf=1,in_order=0,packed_vq=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1

+
+5. Bind virtio port to vfio-pci in both two VMs::
+
+	modprobe vfio enable_unsafe_noiommu_mode=1
+	modprobe vfio-pci
+	echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
+	./usertools/dpdk-devbind.py --bind=vfio-pci 00:05.0
+
+6. Start testpmd in VMs seperately::
+
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 -- -i --rxq=1 --txq=1 --nb-cores=1 --txd=1024 --rxd=1024
+
+7. Loop packets between two virtio-user sides, record performance number with 64b/2000b/8000b/IMIX pkts can get expected::
+
+	testpmd0>set fwd mac
+	testpmd0>start tx_first
+	testpmd0>stop
+	testpmd0>set eth-peer 0 52:54:00:00:00:02
+	testpmd0>start
+	testpmd1>set fwd mac
+	testpmd1>set eth-peer 0 52:54:00:00:00:01
+	testpmd1>set txpkts 64
+	testpmd1>start tx_first
+	testpmd1>show port stats all
+	testpmd1>stop
+	testpmd1>set txpkts 2000

+	testpmd1>set txpkts 64,256,2000,64,256,2000
+	testpmd1>start tx_first
+	testpmd1>show port stats all
+
+8. Quit two testpmd in two VMs, bind virtio-pmd port to virtio-pci,then bind port back to vfio-pci, rerun below cmd 50 times::
+
+	./usertools/dpdk-devbind.py -u 00:05.0
+	./usertools/dpdk-devbind.py --bind=virtio-pci 00:05.0
+	./usertools/dpdk-devbind.py --bind=vfio-pci 00:05.0
+
