+VM2VM vhost-user/virtio-net with DSA driver test plan\r
+======================================================\r
+\r
+Description\r
+===========\r
+\r
+Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.\r
+In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA\r
+channels and one DMA channel can be shared by multiple vrings at the same time.Vhost enqueue operation with CBDMA channels is supported\r
+in both split and packed ring.\r
+\r
+This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with\r
+DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-net topology.\r
+1. check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring \r
+vhost-user/virtio-net mergeable path.\r
+2.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring\r
+and packed ring vhost-user/virtio-net mergeable and non-mergeable path.\r
+3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.\r
+\r
+IOMMU impact:\r
+If iommu off, idxd can work with iova=pa\r
+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).\r
+\r
+Note: \r
+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.\r
+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.\r
+3.When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may\r
+exceed IOMMU's max capability, better to use 1G guest hugepage.\r
+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.\r
+\r
+Prerequisites\r
+=============\r
+\r
+Topology\r
+--------\r
+	Test flow: Virtio-net <-> Vhost-user <-> Testpmd <-> Vhost-user <-> Virtio-net\r
+\r
+Software\r
+--------\r
+	iperf\r
+	qemu: https://download.qemu.org/qemu-6.2.0.tar.xz\r
+\r
+General set up\r
+--------------\r
+1. Compile DPDK::\r
+\r
+	# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>\r
+	# ninja -C <dpdk build dir> -j 110\r
+	For example,\r
+	CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=x86_64-native-linuxapp-gcc\r
+	ninja -C x86_64-native-linuxapp-gcc -j 110\r
+\r
+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::\r
+\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -s\r
+\r
+	Network devices using kernel driver\r
+	===================================\r
+	0000:4f:00.1 'Ethernet Controller E810-C for QSFP 1592' drv=ice unused=vfio-pci\r
+\r
+	DMA devices using kernel driver\r
+	===============================\r
+	0000:6a:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:6f:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:74:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:79:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:e7:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:ec:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:f1:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+	0000:f6:01.0 'Device 0b25' drv=idxd unused=vfio-pci\r
+\r
+Test case\r
+=========\r
+\r
+Common steps\r
+------------\r
+1. Bind DSA devices to DPDK vfio-pci driver::\r
+\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DSA device id>\r
+\r
+	For example, bind 2 DMA devices to vfio-pci driver:\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:e7:01.0 0000:ec:01.0\r
+\r
+.. note::\r
+\r
+	One DPDK DSA device can create 8 WQ at most. Below is an example, where DPDK DSA device will create one and\r
+	eight WQ for DSA deivce 0000:e7:01.0 and 0000:ec:01.0. The value of “max_queues” is 1~8:\r
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:e7:01.0,max_queues=1 -- -i\r
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:ec:01.0,max_queues=8 -- -i\r
+\r
+2. Bind DSA devices to kernel idxd driver, and configure Work Queue (WQ)::\r
+\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd <numDevices * 2>\r
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q <numWq>\r
+\r
+.. note::\r
+\r
+	Better to reset WQ when need operate DSA devices that bound to idxd drvier:\r
+	<dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py --reset <numDevices * 2>\r
+	You can check it by 'ls /dev/dsa'\r
+	numDevices: number of devices, where 0<=numDevices<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0\r
+	numWq: Number of workqueues per DSA endpoint, where 1<=numWq<=8\r
+\r
+	For example, bind 2 DMA devices to idxd driver and configure WQ:\r
+\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0\r
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0\r
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 2\r
+	Check WQ by 'ls /dev/dsa' and can find "wq0.0 wq2.0 wq2.1 wq2.2 wq2.3"\r

+\r
+	testpmd>show port xstats all\r
+\r
+Test Case 2: VM2VM vhost-user/virtio-net split ring mergeable path 8 queues test with large packet payload with dsa dpdk driver\r

+Test Case 16: VM2VM vhost-user/virtio-net packed ring mergeable 16 queues test with large packet payload with dsa dpdk and kernel driver\r
+------------------------------------------------------------------------------------------------------------------------------------------\r
+This case uses iperf and scp to test the payload of large packet (larger than 1MB) is valid after packets forwarding in\r
+vm2vm vhost-user/virtio-net packed ring mergeable path when vhost uses the asynchronous enqueue operations with dsa dpdk\r
+and kernel driver. The dynamic change of multi-queues number also test.\r
+\r
+1. Bind 4 dsa device to vfio-pci and 4 dsa device to idxd like common step 1-2::\r
+\r
+	ls /dev/dsa #check wq configure, reset if exist\r
+\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -u 6a:01.0 6f:01.0 74:01.0 79:01.0 e7:01.0 ec:01.0 f1:01.0 f6:01.0\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0 74:01.0 79:01.0\r
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci e7:01.0 ec:01.0 f1:01.0 f6:01.0\r
+	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 2 0\r

+\r
+2. Launch the Vhost sample by below commands::\r
+\r
+	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-5 -n 4 --file-prefix=vhost -a 0000:e7:01.0 -a 0000:ec:01.0 -a 0000:f1:01.0 -a 0000:f6:01.0 \\r

+\r
+3. Launch VM1 and VM2 with qemu::\r
+\r

+4. On VM1, set virtio device IP and run arp protocal::\r
+\r
+	<VM1># ethtool -L ens5 combined 16\r
+	<VM1># ifconfig ens5 1.1.1.2\r
+	<VM1># arp -s 1.1.1.8 52:54:00:00:00:02\r
+\r
+5. On VM2, set virtio device IP and run arp protocal::\r
+\r
+	<VM2># ethtool -L ens5 combined 16\r
+	<VM2># ifconfig ens5 1.1.1.8\r
+	<VM2># arp -s 1.1.1.2 52:54:00:00:00:01\r
+\r
+6. Scp 1MB file form VM1 to VM2::\r
+\r
+	<VM1># scp <file> root@1.1.1.8:/\r
+\r
+7. Check the iperf performance between two VMs by below commands::\r
+\r
+	<VM1># iperf -s -i 1\r
+	<VM2># iperf -c 1.1.1.2 -i 1 -t 60\r
+\r
+8. Rerun step 6-7 five times.\r
