SPDX-License-Identifier: BSD-3-Clause Copyright(c) 2023 Intel Corporation ======================================================== Vswitch sample test with vhost async data path test plan ======================================================== Description =========== Vswitch sample can leverage DMA to accelerate vhost async data-path from dpdk 20.11. This plan test vhost DMA operation callbacks for DSA PMD and vhost async data-path in vhost sample. --dmas This parameter is used to specify the assigned DMA device of a vhost device. Async vhost-user net driver will be used if --dmas is set. For example –dmas [txd0@wq0.0,txd1@wq0.1,rxd0@wq0.2,rxd1@wq0.3] means use DMA channel wq0.0/wq0.2 for vhost device 0 enqueue/dequeue operation and use DMA channel wq0.1/wq0.3 for vhost device 1 enqueue/dequeue operation. The index of the device corresponds to the socket file in order, that means vhost device 0 is created through the first socket file, vhost device 1 is created through the second socket file, and so on. For more about vswitch example, please refer to the DPDK docment: http://doc.dpdk.org/guides/sample_app_ug/vhost.html Prerequisites ============= Hardware -------- Supportted NICs: NIC that supports VMDQ Software -------- Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz General set up -------------- 1. Compile DPDK and vhost example:: # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc # meson configure -Dexamples=vhost x86_64-native-linuxapp-gcc # ninja -C x86_64-native-linuxapp-gcc -j 110 2. Get the PCI device of DUT, for example, 0000:29:00.0 is NIC port, 0000:6a:01.0 - 0000:f6:01.0 are DSA devices:: # ./usertools/dpdk-devbind.py -s Network devices using kernel driver =================================== 0000:29:00.0 '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:: # ./usertools/dpdk-devbind.py -b vfio-pci For example: # ./usertools/dpdk-devbind.py -b vfio-pci 0000:29:00.0 2. Bind DSA devices to DPDK vfio-pci driver:: # ./usertools/dpdk-devbind.py -b vfio-pci For example, bind 2 DSA devices to vfio-pci driver: # ./usertools/dpdk-devbind.py -b vfio-pci 0000:6a:01.0 0000:6f: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 0000:6a:01.0 and 0000:6f:01.0. The value of “max_queues” is 1~8: # ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:6a:01.0,max_queues=1 -- -i # ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:6f:01.0,max_queues=8 -- -i 3. Bind DSA devices to kernel idxd driver, and configure Work Queue (WQ):: # ./usertools/dpdk-devbind.py -b idxd # ./drivers/dma/idxd/dpdk_idxd_cfg.py -q .. note:: Better to reset WQ when need operate DSA devices that bound to idxd drvier: # ./drivers/dma/idxd/dpdk_idxd_cfg.py --reset You can check it by 'ls /dev/dsa' dsa_idx: Index of DSA devices, where 0<=dsa_idx<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0 wq_num: Number of workqueues per DSA endpoint, where 1<=wq_num<=8 For example, bind 2 DSA devices to idxd driver and configure WQ: # ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0 # ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0 # ./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" Test Case 1: VM2VM virtio-user forwarding test when vhost async operation using DSA dpdk driver ----------------------------------------------------------------------------------------------- This case tests that the imix packets can forward normally in VM2VM topology(virtio-user as front-end) when vhost async operation using DSA dpdk drvier, both split ring and packed ring have been covered. 1.Bind 1 NIC port and 1 DSA device to vfio-pci. 2.
