Hi!
(please CC me, as I'm not subscribed)
I try to give the guest (Windows XP) direct access to one of the
graphics adaptors. However, the driver in the guest always complains:
"Unable to map required address ranges for graphics card."
Any idea what the problem could be? Attached is a kvm log with
DEVICE_ASSIGNMENT_DEBUG = 1.
This is kvm-82 on AMD64 with kernel 2.6.28.
lspci of the graphics adaptor:

Hi Harry
I think we at least have one issue here: currently we can't support graphics
card assignment... Graphics card is more complex than others due to
video bios we must support. So it's not mature now (for both KVM and Xen).
Please wait for our future releases(though I have no idea when it would be
supported, maybe several monthes or longer... :( ).
BTW: We had some experiment to assigned graphics card with Intel VT-d
engine, finally it basicly works but need some dirty hack. And we didn't put
much effort on it later.
And for AMD iommu side, I think you can ask Joerg.

Hi,
thanks for the reply. I've found this on that matter:
http://thread.gmane.org/gmane.comp.emulators.kvm.devel/26785/focus=26971
(device-assignment code doesn't update the cards BAR). Is that the
problem, you're talking about? Or is there something else that's still
missing? So I know what to look for in the changelogs.
Cheers,
harry
PS: I've applied Leendert's patch, but it didn't help

Hi Harry
The thread is talking about option ROM, which offer extra function on some PCI
card, but not video BIOS which is basic component for the graphics card...
Currently we are using emulated Cirrus 54xx by default, as well as it's video
BIOS. Device assignment's video BIOS support would still miss in a period...
We would say explicit that we have supported graphics card after we enable it.
:)
