-VM2VM vhost-user/virtio-net with DSA driver 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
-DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-net topology.
-1. check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring 
-vhost-user/virtio-net mergeable path.
-2.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
-and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
-3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.
-
-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: 
-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.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.
-4.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: Virtio-net <-> Vhost-user <-> Testpmd <-> Vhost-user <-> Virtio-net
-
-Software
---------
-	iperf
-	qemu: https://download.qemu.org/qemu-6.2.0.tar.xz
-
-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 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
-
-2. 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"
