[dpdk-users] HELP: MLX4 problem

[Masaru Kawashima]

Hi, all

I'm trying to use dpdk with Mellanox ConnectX-3.
But, mlnx4 pmd cannot work fine.

Following is my environment:

  OS: CentOS 6.5 (x86_64)
  Mellanox OFED: MLNX_OFED_LINUX-3.1-1.1.0.1-rhel6.5-x86_64
  DPDK: MLNX_DPDK-2.1_1.1

I'm trying to run testpmd, but librte_pmd_mlx4 reports
"ibv_exp_query_device() failed",
and EAL reports "No probed ethernet devices".

What can I do next to work mlx4 pmd fine?


Following is the testpmd's log:
