I'm having huge problems getting pci passthrough to work.
There is a mini-pcie wlan-card (atheros, requires ath9k) which I want to
pass to a domU.
Everytime ath9k is loaded in domU, I get these errors:

PCI memory map error
ath9k: probe of 0000:00:00.0 failed with error -5

The device is of course hidden with pciback.hide for dom0. Xen Version is
3.4.1 and 3.4 (tried both), Kernel in dom0 and domU is 2.6.26 (debian) or
2.6.27 (XCI) or (OpenSUSE Xen kernel patches).

Is there anyone on this list who has even a small idea why this isn't
I'm kind of frustrated... with xen 3.2 it worked without a problem.

Greetings, Leo

Hi Leo,

the interesting part seems to be:
(XEN) mm.c:740:d1 Non-privileged (1) attempt to map I/O space 000febf0

Try enabling permissive mode of pciback or add the device to xend-pci-permissive.sxp (both in dom0)

Best regards,
