Each tx/rx queue +only supports to use one DMA device, but one DMA device can be shared +among multiple tx/rx queues of different vhostpmd ports. + +.. 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. In this patch, + we enable asynchronous data path for vhostpmd. Asynchronous data path is enabled per tx/rx queue, and users need to specify + the DMA device used by the tx/rx queue. Each tx/rx queue only supports to use one DMA device (This is limited by the + implementation of vhostpmd), but one DMA device can be shared among multiple tx/rx queues of different vhost PMD ports. + +Two PMD parameters are added: +- dmas: specify the used DMA device for a tx/rx queue +(Default: no queues enable asynchronous data path) +- dma-ring-size: DMA ring size. +(Default: 4096). + +Here is an example: +--vdev 'eth_vhost0,iface=./s0,dmas=[txq0@0000:00.01.0;rxq0@0000:00.01.1],dma-ring-size=4096' + +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). + +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.
