With RC, you can send larger messages and hardware will perform the
fragmentation.
BTW, ibv_rc_pingpong/ibv_ud_pingpong are pingpong examples - they do not
attempt to measure maximum streaming bandwidth.
Look under the perftests directory for some benchmarks:
e.g. send_bw can measure bandwidth
ib_ucm_cleanup_events has file_mutex while calling ib_destroy_cm_id.
It seems this can deadlock since ib_destroy_cm_id flushes event
handlers, and ib_ucm_event_handler needs file_mutex, too.

I'll be testing the following the next night -
One more thing: Did you use the default message size of the tests?
In ibv_ud_pingpong the default message size is 2K
In ibv_rc_pingpong the default message size is 4K
so, 2 posts and 2 completions where handled in UD for every 1 post and 1
completion in RC ...

Hi,
A few months ago, Leonid Arsh submitted a patch to mthca that enables to
control some of the HCA profile values.
This patch was discussed here (see references below) but wasn't accepted
and somehow got lost and I'd like to re-submit it.
if you want to check performance i suggest you to check the ib_*_lat
ib_*_bw tests and not the pingpong tests which were written as an examples

Howdy,
I see in mthca_main.c the line which states:

svn.

What does this mean? What is the upstream

Hi all,
Is there are registration authority for multicast GIDs? Or at least a
safe way of assigning a range of GIDs to a vendor?

I've converted the libibverbs and libmthca svn history into git (with
some minor cleanups, mostly improving the changelog entries). I've
also created git tags for all of the releases noted in the history.
The git trees
git://git.kernel.org/pub/scm/libs/infiniband/libibverbs.git
The patch is line-wrapped and bizarrely corrupted and won't apply, eg:
+mthca_warn(mdev, num_qp rounded to power of 2 (%d).\n,
+ default_profile.num_qp); +}
This is completely unnecessary:
+#define to_up_power_of_2(x) (x = roundup_pow_of_two(x))
That, in turn, is waiting for net device ref count to get to 0.
But is it normal that the ref count is negative?
No, that's not normal, it's the real bug. Something is doing an extra
dev_put() on the device.

Yes, I will create a vex branch for this in my tree. However, moving

Ah - looks exactly like what I was looking for. Thanks.
Are you planning to mirror libibverbs and libnthca trees on the new
OFA server too (git.kernel.org was overloaded last time)?
I wasn't planning to try and set that up, but git makes it pretty
trivial for someone else to mirror trees wherever they want.
- R.
I have OFED 1.0 stack and running OpenSM on a server connected to a IB
subnet with couple of nodes.
Usually the log file size is small. But ocassionally it is growing too
big and filling up the whole hard disk.

Support provider-specific data in ib_uverbs_cmd_req_notify_cq().
The Chelsio iwarp provider library needs to pass information to the
kernel verb for re-arming the CQ.
