[Xen-users] Xen 3.4.3and CentOS PCIback

[David Gonzalez Herrera <dgonzalezh@xxxxxxxxx>]

Hi,

I'm using CentOS 5.5 x86_64 xen 3.43 from gitco.de and I have an Openvox A1200P voip card and am passing it thru to another centos 5.5 DomU, when I 1st start the domain driver loads and everything seems quite nice and the device works, but after a reboor of the DomU, this is shown on my Dom0 dmesg

Here's Dom0 info

[root@xen ~]# dmesg

pciback 0000:03:01.0: Driver tried to write to a read-only configuration space f
ield at offset 0x44, size 2. This may be harmless, but if you have problems with
 your device:
1) see permissive attribute in sysfs
2) report problems to the xen-devel mailing list along with details of your devi
ce obtained from lspci.

        Memory at fe100000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [40] Power Management version 2

I've hidden the device as described on xen web site adding this to rc.local to bind the device to pciback

BDF=0000:03:01.0
# Unbind a PCI function from its driver as necessary
[ ! -e /sys/bus/pci/devices/$BDF/driver/unbind ] || \
        echo -n $BDF > /sys/bus/pci/devices/$BDF/driver/unbind
# Add a new slot to the PCI Backend's list
echo -n $BDF > /sys/bus/pci/drivers/pciback/new_slot
# Now that the backend is watching for the slot, bind to it
echo -n $BDF > /sys/bus/pci/drivers/pciback/bind

modprobe -v pciback

and the domain config loks like this:

[root@xen ~]# cat /etc/xen/asterisk
kernel = "/boot/vmlinuz-2.6.18-194.17.4.el5xen"
ramdisk = "/boot/initrd-centos-xen.img"
extra = "idebus=66 console=xvc0 selinux=0" # swiotlb=force iommu=soft"
vcpus = 1
acpi = 1
apic = 1
#pae = 1
memory = 512
name = "asterisk"
vif = [ 'mac=00:16:3e:21:f1:00,bridge=br0',
        'mac=00:16:3e:21:f1:01,bridge=br1' ]
#dhcp = "dhcp"

disk = [ 'tap:aio:/xen/asterisk.hdd,sda1,w', ]

# We don't use pygrub, we boot the kernel directly from dom0
#bootloader="/usr/bin/pygrub"
root = "/dev/sda1 ro"

# PCI passthru of the Openvox A1200P PSTN
pci = [ '0000:03:01.0@1' ]

Is this behavior related to what the FAQ and site said about the incapacity of reloading or rebinding an already bound device to a domU?.

This is a card which driver's loaded by dahdi interface drivers from Digium

I don't know what to do in sysfs, altho I've already added this line to xend-pci-prmisive.sxp as 

(unconstrained_dev_ids
     ('e159:0001')
)

Also I added it to xend-pci-quirks.sxp

         '9100:0003'   # Openvox A1200P

When I start the DomU again the device _is_ in fact discovered but when I try to load oit it won't work,

Symptoms:

If I start dom0 fresh and local pciback driver (I dunno how to load it before xenddomains start) and then bring domU it starts nice and card is loaded right

Here's domU loks when everything loads aok

If youc cna share any thoughts on this it'd be greatly appreciated

PD: Trying pv_ops kernel is not viable because I've already tried it and my DomUs would never start.

Thanks again for a great job.
