PCI passthrough on ASUS KGPE-D16

Hi,

would it be possible to passthrough a graphics card to a virtual machine while using Coreboot/Libreboot? The libreboot website says that the motherboard offers full IOMMU-support when using a CPU from the Opteron 6200/6300 series.

Hello opteron/AMD supporter,

You did ask very (very, should say extremely) tricky question, you do know
this (I betcha you do, don't you)??? ;-)

This works just in case anyone was wondering, just remember to pass the 
x-vga=on option for legacy vga boot.
I feel really swell gaming on a coreboot platform.

For some reason though the newer kernels have problems with USB passthru 
which I assume you desire so as always it is software dependent. (Tim I 
will soon post logs as you requested, have been busy.)

Really great news! Would you mind to share some of your hardware-configuration such as the GPU-Model, CPU and RAM? How is the performance?

Thanks!
