-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.
-
-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=static <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=static 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, 0000:6a:00.0 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
-	===================================
-	0000:6a:00.0 '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>
-	<dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q <numWq> <numDevices>
-
-.. 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>
-	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># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0
-	<dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 1
-	Check WQ by 'ls /dev/dsa' and can find "wq0.0 wq1.0 wq1.1 wq1.2 wq1.3"
-
-4. Send tcp 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.
