Xen users - Nov 2011 - GPU pass through support for GTX 480/590

Hi All,

My graphics is slow on HVM guest so To make it fast I want to use GPU pass
through
but in xen source i did not find support for that (device ID for graphics
card GTX 480/590)
I have bellow configuration
1->Intel VT support board
2->xen 4.0
3->GTX 480/590

I have the following query

1->with open source xen 4.0, Can  I use GPU pass-through for GTX 480/590 or
I need to apply some patces
2->Will GPU pass through really make graphics fast on HVM

Thanks,
Akhilesh

I have 2 gtx 590 in SLI mode (4 GPU Quad SLI)
Can''t get any drivers to compile/run under xenserver.
Loaded Gnome GUI on Dom0 and can run it at 720p resolution, but not higher, and
the 720p looks ugly on my 1600p monitor  Can''t get resolution to run
higher

If your system supports IOMMU, you should be able to pass through the
graphics card, but you will almost certainly **not** be able to use the
gfx_passthrough=1 option in your config.

My experience has been limited to ATI cards recently (and intel integrated
graphics, but those are fully supported), but how it''s worked is that
the
BIOS will use the emulated Cirrus VGA adapter, and then after windows takes
full control, it will start to use the passed through adapter.  There are a
couple caveats here:

-I was using Windows as the domU, but I assume you are as well from the
fact that you''re concerned about graphics performance in an HVM
-I had to find and install drivers for the graphics card in the domU before
it would actually use it
-The card was, as mentioned, ATI FirePro

As for performance, I presume you''re currently interacting with the VM
via
VNC or SDL, and yes, you should see a huge, noticeable improvement in
performance.  With the FirePro card, Windows 7 rated graphics performance
at 7.1 out of 7.9, and I was able to enable Aero effects and run fairly
graphics intensive HTML/JS and Flash applications via Chrome.
