           Summary: ISDN cards with HFC-s chipset do not work in DomU's
           Product: Xen
           Version: 3.0.3
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hardware Support
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: patrick@xxxxxxxxxx


I am using the pciback.hide kernel argument to hide two ISDN pci cards from
Dom0, which does work great. Of course I am doing to because I want to use
these cards in a DomU exclusively.
First of all, I have to alter my /etc/xen/xend-pci-permissive.sxp file to be
able to initialize my cards in the DomU environment:
xenmeister:~# cat /etc/xen/xend-pci-permissive.sxp | grep -v ^#
(unconstrained_dev_ids
    ('1397:2bd0')
)

These are the cards I am talking about:
xenmeister:~# lspci | grep HFC
02:02.0 Network controller: Cologne Chip Designs GmbH ISDN network controller
[HFC-PCI] (rev 02)
02:04.0 Network controller: Cologne Chip Designs GmbH ISDN network controller
[HFC-PCI] (rev 02)

The driver I am using is "zaphfc" and you can find the source code (~900 lines
of code) here:
