RE: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
|
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 From: Mr. Teo En Ming (Zhang Enming) [mailto:space.time.universe@xxxxxxxxx] Sent: 2009年11月1日 22:08 To: Konrad Rzeszutek Wilk Cc: Jeremy Fitzhardinge; xen-devel@xxxxxxxxxxxxxxxxxxx; Han, Weidong; space.time.universe@xxxxxxxxx; xen-users@xxxxxxxxxxxxxxxxxxx Subject: Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1) 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.
