Subject: [dpdk-users] Unable to recognize master/representor on the multiple IB devices
Date: Sat, 22 May 2021 23:43:10 +0545
Message-ID: <CAE3YagLda-mTiteH78mh-KH5RW2Cb5QsgOfT-QetKPWBfiAtoA@mail.gmail.com> (raw)

 Hi, I am getting a DPDK MLX5 probing issue.

   1. 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)
