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 when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) and using 4K-pages memory environment. +1. test Vhost asynchronous data path with DSA driver in the PVP topology environment with testpmd. +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 and non-mergeable path. +4. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring. +5. Vhost-user using 1G hugepges and virtio-user using 4k-pages. + +DPDK 19.02 add support for using virtio-user without hugepages. 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. + +Note: +1. When DMA devices 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 the suite has not yet been automated. + +Prerequisites +============= + +General set up +-------------- +1. Turn off transparent hugepage in grub by adding GRUB_CMDLINE_LINUX="transparent_hugepage=never". + +2.

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 the following features when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in loopback virtio-user topology. +1. Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched, +virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed. +This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes split ring mergeable, non-mergeable, inorder mergeable, +inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable, vectorized path. +2. Check payload valid after packets forwarding many times. +3. Stress test with large chain packets. + +IOMMU impact: +If iommu off, idxd can work with iova=pa +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). + +Note: +1. When DMA devices 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 the suite has not yet been automated. + +Topology +-------- + Test flow: Vhost-user <-> Virtio-user + +General set up +-------------- +1.

It enables applications, +like OVS, to save CPU cycles and hide memory copy overhead, thus achieving higher throughput. +Vhost doesn't manage DMA devices and applications, like OVS, need to manage and configure DSA +devices. Applications need to tell vhost what DSA devices to use in every data path function call. +This design enables the flexibility for applications to dynamically use DMA channels in different +function modules, not limited in vhost. 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. + +IOMMU impact: +If iommu off, idxd can work with iova=pa +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). + +Note: 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. + +Prerequisites +============= + +Topology +-------- + Test flow: TG-->NIC-->Vhost-user-->Virtio-user-->Vhost-user-->NIC-->TG + +Hardware +-------- + Supportted NICs: ALL + +Software +-------- + Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz + +General set up +-------------- +1.

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 the following features when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-net topology. +1. 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. +2.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 and non-mergeable path. +3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring. + +IOMMU impact: +If iommu off, idxd can work with iova=pa +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). + +Note: +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. +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. +3.When DMA devices 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. +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. + +Prerequisites +============= + +Topology +-------- + Test flow: Virtio-net <-> Vhost-user <-> Testpmd <-> Vhost-user <-> Virtio-net + +Software +-------- + iperf + qemu: https://download.qemu.org/qemu-6.2.0.tar.xz + +General set up +-------------- +1.

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 the following features when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) in VM2VM virtio-user topology. +1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and payload check. +2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test and payload check. +3. Test indirect descriptor feature. For example, the split ring mergeable inorder path use non-indirect descriptor, the 2000,2000,2000,2000 chain packets will need 4 consequent ring, still need one ring put header. +the split ring mergeable path use indirect descriptor, the 2000,2000,2000,2000 chain packets will only occupy one ring. + +IOMMU impact: +If iommu off, idxd can work with iova=pa +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). + +Note: +1.When DMA devices 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 the suite has not yet been automated. + +Prerequisites +============= + +Topology +-------- + Test flow: Virtio-user -> Vhost-user -> Testpmd -> Vhost-user -> Virtio-user + +General set up +-------------- +1.
