Hello all
I was wondering if anyone could shed some light about what kind
conditions might cause ibv_modify_qp to IBV_QPS_ERR to return EAGAIN?
The error occurred on a QP that probably already had some work

about 3 months, so

Hello all
I have a single machine setup with a dual port Mellanox FDR controller
with a cable marked "FDR" connected between the two ports.
OpenSM is running on the machine to make the ports active.
However, as far as I can read the ibv_devinfo output, it seems to
report that I'm only getting QD

Out of curiosity, what would be the significance if the answer to this
question was yes?

Hello all
Can anyone recommend something I can read to find out more about how
IPoIB bonding and librdmacm work together?
Some googling seems to allude to the fact that patches in this area
went in a few years ago, but I'd like to find some detailed
information about how it works.
I would also l

Hello all
Is there some kind of limit that would prevent me from registering
more than 32 GiB worth of memory regions with ibv_reg_mr in

Hello all
We've hit a kernel panic running 3.1.1-2.fc16.x86_64 on Fedora 16 when
registering 144 buffers of 32 MB each.
We're using libibverbs-1.1.5-5.fc16.x86_64.
Any help would be appreciated. Would a firmware upgrade make a difference?
