Did you try on the host outside of any container? Please could you try following commands (variables to be replaced)? dpdk-hugepages.py --reserve 1G ip link set $netdev netns $container docker run --cap-add SYS_NICE --cap-add IPC_LOCK --cap-add NET_ADMIN \ --device /dev/infiniband/ $image echo show port summary all | dpdk-testpmd --in-memory -- -i > 706a37a35d29:/usr/local/lib # ls -1 | grep mlx > librte_common_mlx5.so > librte_common_mlx5.so.21 > librte_common_mlx5.so.21.0 > librte_net_mlx5.so > librte_net_mlx5.so.21 > librte_net_mlx5.so.21.0 > > But I failed to run the process with following error. > (MIDHAUL_PCI_ADDR:0000:12:01.0, BACKHAUL_PCI_ADDR:0000:12:01.1) > > --- > > mlx5_pci: unable to recognize master/representors on the multiple IB devices > common_mlx5: Failed to load driver = mlx5_pci. > EAL: Requested device 0000:12:01.0 cannot be used > mlx5_pci: unable to recognize master/representors on the multiple IB devices > common_mlx5: Failed to load driver = mlx5_pci. > EAL: Requested device 0000:12:01.1 cannot be used > EAL: Bus (pci) probe failed. > > --- > > For the success case of pci address 12:01.2, it showed following messages. > > --- > > EAL: Detected 64 lcore(s) > EAL: Detected 2 NUMA nodes > EAL: Multi-process socket /var/run/dpdk/nah2/mp_socket > EAL: Probing VFIO support... > EAL: VFIO support initialized > EAL: PCI device 0000:12:01.2 on NUMA socket 0 > EAL: probe driver: 15b3:1016 net_mlx5 > net_mlx5: MPLS over GRE/UDP tunnel offloading disabled due to old > OFED/rdma-core version or firmware configuration > net_mlx5: port 0 the requested maximum Rx packet size (2056) is larger than a > single mbuf (2048) and scattered mode has not been requested > USER1: rte_ip_frag_table_create: allocated of 6291584 bytes at socket 0 > > --- > > BR/Jaeeun
