[ewg] ibv_devinfo: No IB devices found for qib?

[Chen, Mei-Jen]

Hi,

I have installed OFED-3.5 on Ubuntu 12.04 with an Intel HCA QLE7340. I intended to use qperf to measure RDMA performance, but encounter problems. So I am checking what could be missing.

When $ ibv_devinfo
libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs0
No IB devices found

What device that ibv_devinfo is looking for?

The device driver ib-qib is up.
$ibstat: seems OK
