[ATrpms-users] xen and ivtv (PVR-150)

[Wayne Vosberg]

With the following installed:

xen-3.0.3-0.1.rc3
xen-libs-3.0.3-0.1.rc3
ivtv-kmdl-2.6.18-1.2849.fc6xen-0.8.1-122.fc6.at
kernel-xen-2.6.18-1.2849.fc6

I try to 'modprobe ivtv' in domU and with or without
"swiotlb=force"  I get the attached error.   In dom0
it works with "swiotlb=force" but not without (same error).

Note - when trying to use ivtv in domU I 'modprobe pciback'
in /etc/rc.local and have 'options pciback hide=(0000:00:09.0)'
in /etc/modprobe.conf and add 'pci=['0000:00:09.0']' to
/etc/xen/<domU config>

Has anyone had success with ivtv in domU?

thx,
Wayne
