+PVP vhost async operation with DSA driver test plan
+====================================================
+
+Description
+===========
+
+This document provides the test plan for testing Vhost asynchronous
+data path with DSA driver (kernel IDXD driver and DPDK vfio-pci driver)
+in the PVP topology environment with testpmd.
+
+DSA 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.
+Linux kernel and DPDK provide DSA driver (kernel IDXD driver and DPDK vfio-pci driver),
+no matter which driver is used, DPDK DMA library is used in data-path to offload copies
+to DSA, and the only difference is which driver configures DSA. It enables applications,
+like OVS, to save CPU cycles and hide memory copy overhead, thus achieving higher throughput.
+Vhost doesn't manage DMA devices and applications, like OVS, need to manage and configure DSA
+devices. Applications need to tell vhost what DSA devices to use in every data path function call.
+This design enables the flexibility for applications to dynamically use DMA channels in different
+function modules, not limited in vhost. 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.
+
+IOMMU impact:
+If iommu off, idxd can work with iova=pa
+If iommu on, kernel dsa driver only can work with iova=va by program IOMMU, can't use iova=pa(fwd not work due to pkts payload wrong).
+
+Note: DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd, and the suite has not yet been automated.
+
+Prerequisites
+=============
+
+Topology
+--------
+	Test flow: TG-->NIC-->Vhost-user-->Virtio-user-->Vhost-user-->NIC-->TG
+
+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
+	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"
+
+4. Send imix packets [64,1518] to NIC by traffic generator::
+
+	The 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 split ring all path vhost enqueue operations with 1:1 mapping between vrings and dsa dpdk driver channels
+---------------------------------------------------------------------------------------------------------------------------
+This case uses testpmd and Traffic Generator(For example, Trex) to test performance of split ring in each virtio path with 1 core and 1 queue
+when vhost uses the asynchronous enqueue operations with dsa dpdk driver and the mapping between vrings and dsa virtual channels is 1:1.
+Both iova as VA and PA mode, 'mac fwd' and 'csum fwd' have been tested.

+	testpmd>set fwd mac
+	testpmd>start
+
+4. Send imix packets [64,1518] from packet generator, check the throughput can get expected data::
+
+	testpmd>show port stats all
+
+5. Stop vhost port, check that there are packets in both directions of RX and TX in each queue from vhost log::
+
+	testpmd>stop
+
+6. Restart vhost port and send imix packets again, then check the throuhput can get expected data::
+

+with dsa dpdk driver and if the vhost-user can work well when the queue number dynamic change. Both iova as VA and PA mode have beed tested.
+
+1. Bind 8 dsa devices and 1 NIC port to vfio-pci like common step 1-2::
