The --no-huge mode was augmented to use memfd-backed memory \n+(on systems that support memfd), to allow using virtio-user-based NICs without hugepages.\n+\n+Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.\n+In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA \n+channels and one DMA channel can be shared by multiple vrings at the same time. Vhost enqueue operation with CBDMA channels is supported\n+in both split and packed ring.\n+\n+This document provides the test plan for testing some basic functions with CBDMA device in 4K-pages memory environment.\n+1. Test split and packed ring virtio path in the PVP topology environmet.\n+2. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring\n+vhost-user/virtio-net mergeable path.\n+3.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring and packed ring \n+vhost-user/virtio-net mergeable path.\n+4. Vhost-user using 1G hugepges and virtio-user using 4k-pages.\n+\n+Note:\n+1. When CBDMA channels are bound to vfio driver, VA mode is the default and recommended.\n+ For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.\n+2. DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. And case 4-5 have not yet been automated.\n+\n+For more about dpdk-testpmd sample, please refer to the DPDK docments:\n+https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html\n+For virtio-user vdev parameter, you can refer to the DPDK docments:\n+https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.\n+\n+Prerequisites\n+=============\n+\n+Software\n+--------\n+Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+\n+General set up\n+--------------\n+1. Turn off transparent hugepage in grub by adding GRUB_CMDLINE_LINUX=\"transparent_hugepage=never\".\n+ \n+2. Compile DPDK::\n+\n+\t# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>\n+\t# ninja -C <dpdk build dir> -j 110\n+ For example:\n+ CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=x86_64-native-linuxapp-gcc\n+ ninja -C x86_64-native-linuxapp-gcc -j 110\n+\n+3. Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::\n+\n+\t<dpdk dir># ./usertools/dpdk-devbind.py -s\n+\n+\tNetwork devices using kernel driver\n+\t===================================\n+\t0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci\n+\n+\tDMA devices using kernel driver\n+\t===============================\n+\t0000:00:04.0 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci\n+\t0000:00:04.1 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci\n+\n+4.
