+vhost async operation with DSA driver using 4K-pages 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 some basic functions when Vhost-user using asynchronous data path with
+DSA driver (kernel IDXD driver and DPDK vfio-pci driver) and using 4K-pages memory environment.
+1. test Vhost asynchronous data path with DSA driver in the PVP topology environment with testpmd.
+2. 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.
+3.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.
+4. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.
+5. Vhost-user using 1G hugepges and virtio-user using 4k-pages.
+
+DPDK 19.02 add support for using virtio-user without hugepages. The --no-huge mode was augmented to use memfd-backed
+memory (on systems that support memfd), to allow using virtio-user-based NICs without hugepages.
+
+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, and the suite has not yet been automated.
+
+Prerequisites
+=============
+
+General set up
+--------------
+1. Turn off transparent hugepage in grub by adding GRUB_CMDLINE_LINUX="transparent_hugepage=never".
+
+2. 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
+
+3. 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
+
+ 4DMA devices using kernel driver
+ 4===============================
+ 40000:6a:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:6f:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:74:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:79:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:e7:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:ec:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:f1:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 40000:f6:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+
+4. Prepare tmpfs with 4K-pages::
+
+ mkdir /mnt/tmpfs_4k
+ mkdir /mnt/tmpfs_4k_2
+ mount tmpfs /mnt/tmpfs_4k -t tmpfs -o size=4G
+ mount tmpfs /mnt/tmpfs_4k_2 -t tmpfs -o size=4G
+
+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"
+
