Re: [Xen-users] AsteriskNOW on Xen Choppiness

[francisco javier funes nieto <esencia@xxxxxxxxx>]

Not important problems to use this card with pci-passthrough,
pciback.hide in dom0 and pci definition in domU config file. It's a
pci-e model.

domU:

asterisk:~# lspci -v
00:00.0 ISDN controller: Cologne Chip Designs GmbH ISDN network
Controller [HFC-4S] (rev 01)
        Subsystem: Cologne Chip Designs GmbH Device b761
        Flags: medium devsel, IRQ 18
        I/O ports at e800 [size=8]
        Memory at feaff000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [40] Power Management version 2
        Kernel driver in use: wcb4xxp
        Kernel modules: wcb4xxp

asterisk:~# uname -a
Linux asterisk.canonigos.es 2.6.26-2-xen-amd64

dom0:

main2:/etc/xen# dmesg|grep seizing
[    1.060045] pciback 0000:03:04.0: seizing device

main2:/etc/xen# xm info|grep xen_caps
xen_caps               : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32
hvm-3.0-x86_32p hvm-3.0-x86_64
