This plan test\n-vhost async operation with dsa driver (kernel IDXD driver and DPDK vfio-pci driver) in vhost sample.\n-For more about vswitch example, please refer to the DPDK docment:http://doc.dpdk.org/guides/sample_app_ug/vhost.html\n-\n-Note:\n-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.\n-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.\n-3.The suite has not yet been automated.\n-\n-Prerequisites\n-=============\n-\n-Software\n---------\n-Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n-qemu: https://download.qemu.org/qemu-6.2.0.tar.xz\n-iperf\n-\n-General set up\n---------------\n-1. Compile DPDK and vhost example::\n-\n-\t# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>\n-\t# meson configure -Dexamples=vhost <dpdk build dir>\n-\t# ninja -C <dpdk build dir> -j 110\n-\tFor example,\n-\tCC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=x86_64-native-linuxapp-gcc\n-\tninja -C x86_64-native-linuxapp-gcc -j 110\n-\n-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::\n-\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -s\n-\n-\tNetwork devices using kernel driver\n-\t===================================\n-\t0000:4f:00.1 'Ethernet Controller E810-C for QSFP 1592' drv=ice unused=vfio-pci\n-\n-\tDMA devices using kernel driver\n-\t===============================\n-\t0000:6a:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:6f:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:74:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:79:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:e7:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:ec:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:f1:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\t0000:f6:01.0 'Device 0b25' drv=idxd unused=vfio-pci\n-\n-Test case\n-=========\n-\n-Common steps\n-------------\n-1. Bind 1 NIC port to vfio-pci::\n-\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>\n-\tFor example:\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:4f.1\n-\n-2.Bind DSA devices to DPDK vfio-pci driver::\n-\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DSA device id>\n-\tFor example, bind 2 DMA devices to vfio-pci driver:\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:e7:01.0 0000:ec:01.0\n-\n-.. note::\n-\n-\tOne DPDK DSA device can create 8 WQ at most. Below is an example, where DPDK DSA device will create one and\n-\teight WQ for DSA deivce 0000:e7:01.0 and 0000:ec:01.0. The value of “max_queues” is 1~8:\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:e7:01.0,max_queues=1 -- -i\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:ec:01.0,max_queues=8 -- -i\n-\n-3. Bind DSA devices to kernel idxd driver, and configure Work Queue (WQ)::\n-\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b idxd <numDevices * 2>\n-\t<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q <numWq> <numDevices>\n-\n-.. note::\n-\n-\tBetter to reset WQ when need operate DSA devices that bound to idxd drvier:\n-\t<dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py --reset <numDevices * 2>\n-\tYou can check it by 'ls /dev/dsa'\n-\tnumDevices: number of devices, where 0<=numDevices<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0\n-\tnumWq: Number of workqueues per DSA endpoint, where 1<=numWq<=8\n-\n-\tFor example, bind 2 DMA devices to idxd driver and configure WQ:\n-\n-\t<dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0\n-\t<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0\n-\t<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 2\n-\tCheck WQ by 'ls /dev/dsa' and can find \"wq0.0 wq2.0 wq2.1 wq2.2 wq2.3\"\n-\n-Test Case 1: PVP performance vhost async enqueue operation with dsa dpdk channel\n----------------------------------------------------------------------------------\n-This case uses vhost example to test performance of split and packed ring when vhost uses the asynchronous enqueue operations \n-with dsa dpdk driver in PVP topology environment.\n-\n-1. Bind one physical port(4f:00.1) and one dsa device(6a:01.0) to vfio-pci like common step 1-2.\n-\n-2. On host, launch dpdk-vhost by below command::\n-\n-\t<dpdk dir># ./<dpdk build dir>/examples/dpdk-vhost -l 2-3 -n 4 -a 0000:4f:00.0 -a 0000:6a:01.0,max_queues=1 -- \\\n-\t-p 0x1 --mergeable 1 --vm2vm 1  --stats 1 --socket-file /tmp/vhost-net --dmas [txd0@0000:6a:01.0-q0] --client\n-\n-3.

Start pkts from virtio-user side to let vswitch know the mac addr::\n-\n-\ttestpmd>set fwd mac\n-\ttestpmd>start tx_first\n-\ttestpmd>stop\n-\ttestpmd>start\n-\n-5. Inject pkts (packets length=64...1518) separately with dest_mac=virtio_mac_addresss (specific in above cmd with 00:11:22:33:44:10) to NIC using packet generator, record pvp (PG>nic>vswitch>virtio-user>vswitch>nic>PG) performance number can get expected.\n-\n-6. Quit and re-launch virtio-user with packed ring size not power of 2::\n-\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0  \\\n-\t--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,packed_vq=1,server=1,queue_size=1025 -- -i --rxq=1 --txq=1 --txd=1025 --rxd=1025 --nb-cores=1\n-\n-7. Re-test step 4-5, record performance of different packet length.\n-\n-8. Quit and re-launch virtio-user with split ring::\n-\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0 \\\n-\t--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,server=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1\n-\n-9. Re-test step 4-5, record performance of different packet length.\n-\n-Test Case 2: PVP vhost async enqueue operation with two VM and 2 dsa channels\n-------------------------------------------------------------------------------\n-This case uses vhost example to test split and packed ring when vhost uses the asynchronous enqueue operations \n-with dsa dpdk driver in PVP topology environment with 2 VM and 2 queues.\n-\n-1. Bind one physical port and 2 dsa devices to vfio-pci like common step 1-2.\n-\n-2. On host, launch dpdk-vhost by below command::\n-\n-\t<dpdk dir># ./<dpdk build dir>/examples/dpdk-vhost -l 2-3 -n 4 -a 0000:18:00.0 -a 0000:6a:01.0,max_queues=2 -a 0000:6f:01.0,max_queues=1 -- \\\n-\t-p 0x1 --mergeable 1 --vm2vm 1  --stats 1 --socket-file /tmp/vhost-net0 --socket-file /tmp/vhost-net1 --dmas [txd0@0000:6a:01.0-q1,txd1@0000:6f:01.0-q0] --client\n-\n-3. launch two virtio-user ports::\n-\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0 \\\n-\t--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net0,queues=1,server=1,mrg_rxbuf=1,in_order=0,packed_vq=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1\n-\n-\t<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 7-8 -n 4 --no-pci --file-prefix=testpmd1 \\\n-\t--vdev=net_virtio_user1,mac=00:11:22:33:44:11,path=/tmp/vhost-net1,queues=1,server=1,mrg_rxbuf=1,in_order=1,vectorized=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1\n-\n-4.
