OFED allows code that is not upstream to be included as technology preview (not built by default) to allow people to use it. In the case of the Xeon-Phi code that uses peer to peer PCI transfers, it is not clear the Linux community would every accept it the way it is now. I saw on the list a year or so back some patches that Mellanox submitted to allow support for PCI peer to peer transfers like what the Xeon Phi code needs, and they got puked all over. So until that gets all worked out in Linux, I suspect this code will have to stay out of tree. _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/mailman/listinfo/ewg
