Re: [Xen-users] can not unbind pci device, xen kernel, openSUSE

[István HERCZEG <advoper@xxxxxxxxx>]

Hi,

thank you for quick answer. You was right I missed the format. But I still have a problem. Continue the PCI unbind procedure the wiki says[1]:

echo -n "0000:00:1a.0" /sys/bus/pci/drivers/pciback/new_slot

and ..
echo -n "0000:00:1a.0" /sys/bus/pci/drivers/pciback/bind_cat

In my openSUSE 11.2 there are no /sys/bus/pci/drivers/pciback directory. OK. I have /sys/bus/pci/drivers/pci-stub maybe this would be nice[2]:

continuing the procedure:

echo -n "0000:00:1a.0" /sys/bus/pci/drivers/pci-stub/new_slot
-bash: new_slot: No such file or directory
echo -n "0000:00:1a.0" /sys/bus/pci/drivers/pci-stub/bindcat
-bash: bindcat: No such file or directory

I get these messages ...

Regards,
Istvan

then echo -n "domain:bus:slot:.role" > /sys/bus/pci....

at this point:
echo -n "0000:1a.0" > /sys/bus/pci/drivers/ehci_hcd/unbind

i get an error message:
-bash: echo: write error: No such device

I'm not expert on this but I think the format you want is 0000:XX:XX.X, so try "0000:00:1a.0" and see how that goes.
