I have installed the mlx5/ofed driver 2. I have loaded the kernel modules. EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: No available hugepages reported in hugepages-2048kB EAL: Probing VFIO support... EAL: Probe PCI driver: mlx5_pci (15b3:1013) device: 0000:5e:00.0 (socket 0) mlx5_pci: unable to recognize master/representors on the multiple IB devices common_mlx5: Failed to load driver = mlx5_pci. EAL: Requested device 0000:5e:00.0 cannot be used EAL: Bus (pci) probe failed. As for the 'failing to load mlx5_pci' driver, I can see that the mlx5_core driver is loaded. dpdk-devbind.py -s Network devices using kernel driver =================================== 0000:5e:00.0 'MT27700 Family [ConnectX-4]' if=enp94s0 drv=mlx5_core unused= What does failing to recognize master/representors on multiple IB devices mean? My configuration is: CentOS 7.9, Linux Kernel 5.12, OFED 4.9 (LTS)
