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

[Rupert Dance]

Hello Mei,

 

Unfortunately OFED 3.5 does not support Ubuntu at this point. Please see the
release notes attached for a list of supported OSs. I have also "cc" the OFA
User list because there are some members who have worked with Ubuntu and
have provided support for InfiniBand using different versions of OFED. I
believe we will see some response.

 

Thanks

 

Rupert

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

 

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
