Greetings Xen user community, I am interested in using Mellanox ConnectX cards with SR-IOV capabilities to passthrough pci-e Virtual Functions (VFs) to Xen guests. The hope is to allow for the use of InfiniBand directly within virtual machines and thereby enable a plethora of high performance computing applications that already leverage InfiniBand interconnects. However...

...Talked with Michael, and it's better for you to merge the new version in this series. Sorry for not spotting this before.

...between Jason's patches and what's in my tree also exist. How big is the dependency? Can I pick it up with your ack? Also, mips build failures need to be dealt with. > > > The following series of patches provide VDPA support for Mellanox > devices.

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>
