[Xen-users] Problems with serial IO PCI card in DomU

["S. Kremer" <sk71@xxxxxx>]

Hi @ll,

i have problems to use serial io pci card under domu.

Serial card:
08:03.0 Multiport serial controller: SUNIX Co., Ltd. Device 1999

I compiled the snx driver/modules at dom0and load successfully the module:

================ Found  2 SUNIX port , list informations
====================
                                             SUNIX driver ver -- 2.0.0.0

ttySNX0 --
SUNIX 5037 Series (bus:8 device: 3) , base address = ec00,    irq = 16

ttySNX1 --
SUNIX 5037 Series (bus:8 device: 3) , base address = ec08,    irq = 16

=============================================================================

Then i use the following commands to unbind the pci card from xen

echo -n 0000:08:03.0 > /sys/bus/pci/drivers/pciback/new_slot
echo -n 0000:08:03.0 > /sys/bus/pci/drivers/pciback/bind

and my domU config:

pci = [ '08:03.0']
irq = [ 16 ]
ioports = [ "ec00-ec07", "ec08-ec0f" ]

in domU lspci shows me the correct Sunix card, but i can not insert
module to use the card (io ports) in domU.

What can I do to make the serial IO card running at domU?

I would like use this card or one port of it for a analog fax modem and
hylafax in domU. Perhaps there is another way to solve my problem.


Best regards
Stefan
