Re: [Xen-users] pciback.hide with ISDN Cards

[Gerhard Possler <gerhard.possler@xxxxxxxxxx>]

Hi all,

Thaks to Stephan... his mail inspired
me to look closer to the syntax :-)
and now it works, so here is the config:

In /boot/grub/menu.lst:
title XEN -- openSUSE 10.3 - PAE
    root (hd0,4)
    kernel /xen-pae.gz
    module /vmlinuz-2.6.22.13-0.3-xenpae root=/dev/mapper/nvidia_deihceca_part7
vga=normal resume=/dev/mapper/nvidia_deihceca_part6 splash=silent showopts
pciback.hide=(0000:01:00.0)(0000:01:01.0)
    module /initrd-2.6.22.13-0.3-xenpae

In /etc/init.d/boot.local: 
# HFC ISDN PCI Devices remove from Dom0
and also set permissive
modprobe pciback hide='(01:00.0)(01:01.0)'
echo -n 0000:01:00.0 > sys/bus/pci/drivers/pciback/permissive
echo -n 0000:01:01.0 > sys/bus/pci/drivers/pciback/permissive

Well the entry in /var/log/boot.msg
is an little bit disturbing but if you ignore it pci delegation will work
;-)
<3>Unknown boot option `pciback.hide=(0000:01:00.0)(0000:01:01.0)':
ignoring
to be sure sure look at /var/log/messages
and you will find:
Dec 20 09:51:20 print kernel: pciback
0000:01:00.0: seizing device
Dec 20 09:51:20 print kernel: pciback 0000:01:01.0: seizing device
Dec 20 09:51:20 print kernel: ACPI: PCI Interrupt Link [LNKB] enabled at
IRQ 18
Dec 20 09:51:20 print kernel: ACPI: PCI Interrupt 0000:01:01.0[A] ->
Link [LNKB] -> GSI 18 (level, low) -> IRQ 21
Dec 20 09:51:20 print kernel: ACPI: PCI interrupt for device 0000:01:01.0
disabled
Dec 20 09:51:20 print kernel: ACPI: PCI Interrupt Link [LNKA] enabled at
IRQ 17
Dec 20 09:51:20 print kernel: ACPI: PCI Interrupt 0000:01:00.0[A] ->
Link [LNKA] -> GSI 17 (level, low) -> IRQ 22
Dec 20 09:51:20 print kernel: ACPI: PCI interrupt for device 0000:01:00.0
disabled

so you may start the DomU, add the devices
to the DomU config:
...
pci=[ '01:00.0','01:01.0' ]
...

PS: Happy New Year

Subject	Re: [Xen-users] pciback.hide with ISDN Cards

Hi,

we've done this with a fritz pci isdn card successfully.
as that machine in no way uses the isdn stack at dom0,
i removed the kernel module and rebuild the dom0's initrd
without this module (I didn't trust the /etc/modprobe ;) )

one line from the lspci:

03:01.0 Network controller: AVM Audiovisuelles MKTG & Computer System
GmbH Fritz!PCI v2.0 ISDN (rev 02)

the grub entry:

title           Xen 3.1-i386-pae / Ubuntu, kernel
2.6.20-100-server
root            (hd0,1)
kernel          /xen-3.1-i386-pae.gz
module          /vmlinuz-2.6.20-100-server root=UUID=09503299-c560-45de-b69d-8d98eadc7b23
ro console=tty0 irq=poll
pciback.hide=(03:01.0)
module          /initrd.img-2.6.20-100-server
quiet
savedefault

the domU conf:

kernel = '/boot/vmlinuz-2.6.19-4-server'
ramdisk = '/boot/initrd.img-2.6.19-4-server'
memory  = '1832'
cpus="0"
root    = '/dev/sda1 ro'
disk    = [ 'phy:vg0/XXXXX-disk,sda1,w', 'phy:vg0/XXXXX-swap,sda2,w'
]
name    = 'XXXXX'
vif  = [ 'mac=XX:XX:XX:XX:XX, bridge=xenbr0', ' mac=XX:XX:XX:XX:XX:XX,
bridge=xenbr1' ]
pci = [ '03:01.0' ]

on_reboot   = 'restart'
on_crash    = 'restart'

Hope this helps.

Regards,

Stephan
