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

[Andrew Bobulsky <rulerof@xxxxxxxxx>]

Hello Adrien,

I've been tinkering with  GA-990FX-GD70 the past few days, and its
lspci is remarkably similar to yours!  Considering that the logical
layout (from a PCI standpoint) should be identical, you should be able
to get PCI passthrough to work.

Without special patches, the gfx_passthru option won't work right, so
leave it = 0, or undefined.  This will pass the PCIe video card as a
secondary graphics adapter, and will work after your DomU OS boots up.
 I can confirm that it works with my AMD gfx card on Windows 7, but
haven't gotten it to work in Ubuntu DomU yet.  That may be a kernel
thing.  Additionally, the sound device, which for me also shows up as
00:14.2, works equally as well.

I might suggest you start by making sure you hide all the devices,
boot your Dom0, then SSH into the box, start your VM, VNC into the VM,
and try adding the devices one at a time with "xl pci-attach" (or "xm
pci-attach").  I found this was easiest with a USB controller or the
sound card.  Once you get one thing working, try adding more, and see
what you get! :)

Cheers,
Andrew Bobulsky
