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

[Chen, Mei-Jen]

Hello Ira,

I just downloaded libipathverbs-1.2. I think I have compiled and installed to Ubuntu successfully. But ibv_devinfo still couldn't find the device.
I notice the README didn't list supported hardware of QLE7340 (it did list support for QLE7140 ), do you think this is the reason?

Mei

You need.  (As listed on this page: https://www.openfabrics.org/downloads/MAINTAINERS)

It is likely there is no Ubuntu packaging for it but I don't see why it would not compile.

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

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
