Xen users - May 2006 - confused about pciback

hi,

i tried to get two hfc isdn cards working in Xen 3.0.2-2. but it''st
strange:

Dom0 lspci :
============
0000:00:09.0 Network controller: Cologne Chip Designs GmbH ISDN network
controller [HFC-PCI] (rev 02)

0000:00:0c.0 Network controller: Cologne Chip Designs GmbH ISDN network
controller [HFC-PCI] (rev 02)

-----

/etc/init.d/misdn-init start
-----------------------------------------
 Loading module(s) for your misdn-cards:
-----------------------------------------
modprobe hfcpci protocol=0x2,0x12 layermask=0xf,0x3


lsmod Dom0
==========
hfcpci                 30660  0
mISDN_capi            100780  0
mISDN_dsp             197228  0
l3udss1                42664  0
mISDN_l2               40288  0
mISDN_l1               11304  0
mISDN_core             79936  6
hfcpci,mISDN_capi,mISDN_dsp,l3udss1,mISDN_l2,mISDN_l1
kernelcapi             47008  1 mISDN_capi


And now, DomU

asterisk:~# lspci

0000:00:09.0 Network controller: Cologne Chip Designs GmbH ISDN network
controller [HFC-PCI] (rev 02)
0000:00:0c.0 Network controller: Cologne Chip Designs GmbH ISDN network
controller [HFC-PCI] (rev 02)

asterisk:~# lsmod

capi                   17352  0
capifs                  5672  2 capi
kernelcapi             47008  2 mISDN_capi,capi
genrtc                  8540  0

I can start both, with ISDN, no error at all.

Ok, if i stop misdn und unload the hfc modules in Dom0 and load them
only in the DomU, they won''t work.

I i shutdown the DomU or let it running, and start misdn (load hfc
modules etc.) in Dom0, the phones are working for Dom0.

So, what is my mistake?

Grub:
=====
title Xen 3.0 XenLinux 2.6.16
 root           (hd0,0)
 kernel /xen.gz dom0_mem=64000
 module /vmlinuz-2.6-xen root=/dev/hda5 ro console=tty0  max_loop=64
pciback.hide=(0000:00:0c.0)(0000:00:09.0)


Xen Config:
===========
# standard config

name ="asterisk"
kernel ="/boot/vmlinuz-2.6-xen"
root ="/dev/hda1"
memory = 256
disk
[''phy:/dev/daten/asterisk,hda1,w'',''phy:/dev/daten/asterisk-swap,hda2,w'']

# network

vif = [ '''', ''bridge=xenbr0'' ]
dhcp ="off"
ip="192.168.100.6"
netmask="255.255.255.0"
gateway="192.168.100.254"
hostname="asterisk"
pci=[''00:0c.00'',''00:09.00'']
extra="3"

I''m not familiar with your hardware, but I''d recommend
checking the
kernel logs in your domU (dmesg) for any strange errors or warnings that
maybe you''re not seeing on the console. In addition, check the output
of
"xm dmesg" for any Xen errors. Also, try turning on the permissive
flag
(it enables most writes to the PCI configuration space); it''s found
in /sys/modules/pciback/parameters. Some hardware requires writing to
the PCI configuration space and the security protections in the pciback
module disable that by default.
