Just wanted to give an update on where we are with the InfiniBand IBAL.

After we submitted the IBAL code for review, there has been additional
InfiniBand code put into open source by the major InfiniBand companies,
namely TopSpin, Mellanox, InfiniCon, and Voltaire.
This presents somewhat of a problem because now there are multiple
versions of the various InfiniBand S/W components, Access Layers, and

We now need to review all this code and
determine which code is best to use as a basis for something that
we would eventually try to get into Linux. We hope that people in the
linux community will help us sort through this mess and come up with
a "best of breed" stack out of all the available code.

The Mellanox and Topspin folks along with some people from some of
the national labs are trying to start up a website called,
with data bases, email lists, etc. where people can submit code for
this "best of breed" stack and discuss it. As long as it is truly
open, the linux community is allowed to participate, and the code
is evaluated on it's technical merits, rather than one companies
agenda, this forum might serve as a way for us to sort through this
taking every issue to lkml.

What are your thoughts on how we should proceed ?
