Hi Chet,
the trick is to check out the latest pkg-ofed source from debian SVN
(svn://svn.debian.org/svn/pkg-ofed/) and to update the upstream source
by merging the stuff by extracting the source RPMs or even better by
importing the source directly from the git repos of the OFED user space.
In the "debian" directory there are some patches e.g. which change some
stuff in shell scripts for the dash. These need to be adopted.
But you'll have to ensure that the kernel code matches the OFED user
space. The kernel stuff included in OFED doesn't support latest kernels
and is based on an older code base (e.g. OFED 1.5.4 kernel stuff is
based on 2.6.30). I hope that you don't need iSER. The open-iscsi kernel
stuff in there is also based on 2.6.30 which means that you would need
old open-iscsi user space.
This is why we've decided to follow what they call "upstream" in this
list. This means: Use the OFED kernel code from the matching vanilla
kernel from kernel.org.
Here a simple list of matching code:
OFED-1.5.4 ---> kernel 3.2.x
OFED-1.5.4.1 ---> kernel 3.3.x
I've attached the IB user space HOWTO from Or Gerlitz for the git repos.
Some of the git repos already have a debinan directory.
Do you know how to build Debian packages?
Cheers,
Sebastian

IB user space HOWTO
June 2012
Or Gerlitz <[email protected]>
This little note attempts to get you through how to get the upstream
user-space IB packages, specifically libibverbs/libmlx4/librdmacm and/or
opensm and the IB diags.
Under Fedora / RHEL, installing the INBOX user-space IB/RDMA offering is easy
as
# yum groupinstall "Infiniband Support"
The IB service is called rdma (vs. openibd which used to be the name in older
RHEL/Fedora
releases) and there is an rpm named "rdma" with various scripts. Note that this
will
not install opensm/diags (see below).
If you are seeking the latest RELEASE done by the maintainers, its also
trivial,
the releases are provided in the form of tar balls which you plug into
"rpmbuild -ts" and you have fresh source RPM to build and later install.
Going more hackish, you would need to build the sources from the maintainers
git, the git trees contain spec files, so the process would be to create
the tarballs and then repeat the rpmbuild excercise.
See below links to where there are tarball releases and the git trees where
here gitweb links are provided, they have the git pointer to clone from inside.
Here's the list of maintainers
Roland Dreier <[email protected]> for libibverbs/libmlx4
Sean Hefty <[email protected]> for librdmacm
Alex Netes <[email protected]> for opensm and libibumad
Ira Weiny <[email protected]> for libibmad and the IB diags
Ido Shamai <[email protected]> for perftest (ib_send_bw and friends)
Roland and Sean are also the maintainers of the IB kernel stack.
The mailing list for reporting issues is <[email protected]>,
there's no need for subscription, please make sure to CC the list when
you send email to the maintainer.
Last but not least, make sure to enjoy your work, its really simple,
and please do let me know if/what something is missing here.
