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.
