Xen users - Jul 2012 - Certain PCI passthrough devices don't work

Hello list,
    Using the mainline 3.5-rc6 kernel and yesterday''s xen-unstable,
I''m having trouble passing in some PCI devices. Everything else works
smoothly.
    Attached are some of the relevant logs and configurations. I did
notice from the qemu logs that all the problematic devices have "IRQ
type = INTx" whereas those that are working have "IRQ type
MSI-INTx".
    On the domU side, Windows reports that the devices cannot start
and Ubuntu complained something along the lines of "Invalid USB
capability 0xFF" (for the USB controller I was passing through).

    Kernel version:
        git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
        commit 055c9fa8874fa7261eec7a268366565db84af474
        Merge: 310959e 46bada6
        Author: Linus Torvalds <torvalds@linux-foundation.org>
        Date:   Tue Jul 10 13:24:48 2012 -0700
    Xen version:
        http://xenbits.xen.org/xen-unstable.hg
        parent: 25605:9950f2dc2ee6 tip
         xsm/flask: avoid struct page lookup in mmu_normal_update
        branch: default

    Anyone has any idea how to fix this? It was working before I did
the kernel and xen upgrade.

Thanks!

Due to changeset 25525,

pci_msitranslate = 0 by default


Try

pci_msitranslate = 1

It worked for me :)

Thanks for the reply!

I have that option enabled in my config file. Tried running with it
set to 0 as well, didn''t work either. =(
