[Xen-users] VGA passthrough ? AMD-FX8, GA-990FXA-UD3, G210

[Adrien Urban <adrien.urban@xxxxxxxxxxxxxx>]

Hello,

Like many trying and posting here, I'm new to VGA passthrough.

Computer was bought, checking compatibility from 
http://wiki.xen.org/wiki/VTd_HowTo
The hardware is mostly not exactly on the list, but mainly new versions 
of the same series (I think).

IOMMU "seems" to be working (not 100% sure what to check).

I used debian/wheezy kernel and xen, dom0 and HVM domu. Managed to get 
to "see" audio and video from the DomU, but couldn't get it to "work".
=> screen wouldn't show anything
=> mplayer can't find an audio card.

If I don't hide the pci devices, i can get some sound working on dom0, 
and have console working all right on it.
If I try to pass the devices, I effectively have no screen left giving 
an output for dom0, but the domU still doesn't show anything (tryed with 
gfx_passthru).
I'll be working on it until I figure there is a hardware problem, or get 
it to work, but it might get easier if I could get some hints of what 
i'm doing wrong, if it's something obvious for one of you.
If anyone is willing to help, but need more input, just tell me what 
kind of input you would need.
