Here are the kernel driver changes that go with the user library

Here are the diffs Roland requested for the ipath driver changes
to mmap the completion and receive queues into the user library.
This isn't quite the final version though since I need to implement
QP receive queue resizing and some version checking/handling.

OK, I rolled this into the cma patch in for-2.6.18 branch.
Unfortunately this means that all of the patches in that branch are
rebased, so you'll have to repull my tree if you're tracking it.

Roland, can you pick up this patch for 2.6.18?
Thanks - committed in 8057.

In most cases, I would expect that the IB CM will eventually receive the RTU,
which will generate an event to the RDMA CM to transition the QP into RTS. Th

This is the normal output for rping...
The status error on the completion is 5 (FLUSHED), which is normal.

Sean, I think this is a bug, eh?
If you listen on 0.0.0.0, then the backlog isn't passed down to the
devices because its not stored in the id_priv struct before calling
cma_listen_on_all(). See cma_list_on_dev() which uses
id_priv->backlog...

I am working on a ipathverbs.so version of ibv_poll_cq(),
ibv_post_recv(), and ibv_post_srq_recv() which mmaps the
queue into user space. I found that I needed to modify the
core libibverbs and kernel uverbs code in order to return
the information I need from ib_ipath to the ipathverbs.so
library.
As one of the authors of IB and iWARP, I can say that both Roland and
Todd's responses are correct and the intent of the specifications.
The number of outstanding RDMA Reads are bounded and that is communicated
during session establishment. The ULP can choose to be aware of
this requirement (c

Sounds like maybe the librdma.so that's installed is down-level...
Did you nuke the old one, rerun autgen.sh, configure, make, make install
in the librdmacm directory?

Hi,
I have installed the latest infiniband stack with 2.6.16.20 kernel.
I tested the installation using ibv_rc_pingpong and it works fine.
But, while trying to use rping, I get the following error:
librdmacm: couldn't open rdma_cm ABI version.

Thanks for the review.
The major point you bring up is the fact I intentionally impose the result of

The idea I had was that once the Pkey Manage

Hi Eitan,
Some comments about the patch.
Personally I'm glad to see that you are using tab instead of spaces as
identaion character. But it would be nice if next time you will not mix
the functional changes and identaion fixes in the same patch, but instead
will provide two different patches. Als
