Hi, I''m trying to use a QLogic ipath infiniband card with xen. Unfortunately the ipath driver requires PCI_MSI and PCI_MSI conflicts with xen. Does anyone know the reason for that conflict or how hard it would be to make it work?

Hi Keir, Please pull the ia64 trees: http://xenbits.xensource.com/ext/ia64/xen-unstable.hg http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg This includes updates of acpi related files, save/restore update for pv_ops and bug fixes from Akio, and mini-os update from Samuel Thibault.

Andy, this is the next and hopefully last version. Seems to work fine when replacing the previous patches in your tree. I have some reviews/acks for patch 2 and 3. patch 1 still needs one ack. Can you replace the patches in your tree and carry them along with your changes? old introduction: ----- There are some attempts to unify the dma ops (Christoph) as well as some attempts to make virtio use
