Hi group, We are building a setup with DPDK bound to VF ports of a Netronome Agilio CX 2x40 (NFP4000) SmartNIC. Netronome does some P4 processing of packets, and forwards through SR-IOV to host where dpdk will continue processing.
My problem: in DPDK I can not allocate more than a single RX-queue to the ports. Multiple dpdk processes can not pull from the same queue, which means that my dpdk setup only works with a single core. Binding dpdk to PF ports on a simple Intel 2x10G NIC works without a problem, multiple RX-queues (and hence multiple cores) work fine. I bind dpdk to Netronome VF ports with the igb_uio driver. I have seen vfio-pci mentioned, would using this driver allow multiple RX-queues? We had some problems using this driver, which is why it has not yet been tested. If you need more information, I will be happy providing it Thanks, Jonatan
