[Xen-users] PCI passthrough

[anthony garnier <sokar6012@xxxxxxxxxxx>]

Hi,
I'm currently working on the latest version of xen with debian (lenny), and I have done 2 PCI passthrough, the fisrt one is with eth1 and i got no probleme with this one, but the second one is with a infiniband adapter=> It's not working
I got this message with dmesg on my DomU :

[    4.111023] ib_mthca: Mellanox InfiniBand HCA driver v1.0 (April 4, 2008)
[    4.111047] ib_mthca: Initializing 0000:00:00.0
[    4.111501] ib_mthca 0000:00:00.0: enabling device (0000 -> 0002)

[   15.526765] ib_mthca 0000:00:00.0: Failed to reset HCA, aborting.

Do you know if there is a solution like previously with XEN smartio or Xen-IB  (wich is no more developped) to do  High Performance VMM-Bypass I/O in Virtual Machines.
