Hi En Ming,

I found the line "register_real_device: Error: Binding of interrupt failed! rc=-1". So I guess the Fire-wire device doesn't support MSI, and shares IRQ with other devices. This is the issue I and Jeremy are discussing. You can search mail subject "pv-ops: fix shared irq device passthrough" in mailing list for more details. Pls apply the attached patch to pv-ops dom0 see if it fixes your problem.

Regards,

Weidong

Subject: Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)

Hi All,

I have just installed Slackware64 13.0 64-bit Linux as HVM domU. Please refer to http://enmingteo.wordpress.com/2009/11/01/picture-tutorial-how-to-setup-slackware64-13-0-hvm-domu-with-xen-3-5-unstable-pv-ops-dom0-kernel-2-6-31-4-in-fedora-11-x86-64-dom0/ for more details and screenshots.

I have tried to passthrough the firewire controller on Intel DQ45CB motherboard to Slackware64 13.0 HVM domU but I can't load the kernel modules for it.

Please have a look at the following output within Slackware64 13.0 HVM domU.

From the screenshots of the device manager in the Win XP Home domU,
the OHCI IEEE 1394 firewire controller appears to be working properly.
The Windows drivers for the firewire controller reports that the
firewire controller is working fine.

However, when you connect a firewire-based digital video camera to the
firewire port, it is not detected in the Windows virtual machine.

I will probably have to find time to install a Linux HVM domU and try
to pass through the 1394 controller to it.
