Dear DPDK users,
I am trying to use the VF of the Mellanox 100G NIC enabled by SR-IOV. The
following is what I have done.
1. Add "intel_iommu=on iommu=pt" to kernel command line option,
update-grub, and reboot
2. Install the MLNX-OFED, reboot
3. In default the card is in infiband mode, so I switched it to ethernet
mode (in order to run DPDK application) and reboot.
4. mst start
mlxconfig -d /dev/mst/mt4115_pciconf0 q #query
mlxconfig -d /dev/mst/mt4115_pciconf0 set SRIOV_EN=1 NUM_OF_VFS=1
reboot
5. echo 1 > /sys/bus/pci/devices/0000\:83\:00.0/mlx5_num_vfs
6. modprobe vfio-pci
7. dpdk-devbind.py --status
8. dpdk-devbind.py -b vfio-pci 0000:83:00.1
9. ls -al /dev/vfio
10. docker run -it --privileged --device=/dev/vfio/54:/dev/vfio/54
--device=/dev/vfio/vfio:/dev/vfio/vfio -v /mnt/huge/:/dev/hugepages/ -v
/var/run:/var/run $IMAGEID bash
11. $dpdkapp -c 0x01 --socket-mem=128,128 --file-prefix="docker1"
However, in the EAL part, it does not list any usable devices
EAL: Detected 12 lcore(s)
EAL: Probing VFIO support...
EAL: VFIO support initialized
PMD: bnxt_rte_pmd_init() called for (null)
Error, rte_eth_dev_configure() returns negative!
Can anybody please point out any possible solution? Looking forward to your
reply. Thanks very much for your help.
Best wishes,
Xiaoban
