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. + +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 with CBDMA device in 4K-pages memory environment. +1. Test split and packed ring virtio path in the PVP topology environmet. +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 path. +4. Vhost-user using 1G hugepges and virtio-user using 4k-pages. + +Note: +1. When CBDMA channels 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 case 4-5 have not yet been automated. + +For more about dpdk-testpmd sample, please refer to the DPDK docments: +https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html +For virtio-user vdev parameter, you can refer to the DPDK docments: +https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage. + +Prerequisites +============= + +Software +-------- +Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz + +General set up +-------------- +1.
