Hi
I''ve got a GTX 460 SE EVGA 1024 M and it works for VT-d using Windows
XP as domU. or Ubuntu Lucid as domU
I can not give your any information for GPU because I do not try.
However I do not have a GTX 480.
For NVidia, you need to patch Xen in order to supporting Vt-d.. I maintain the
last patches - as much as I can - for Xen VGA Nvidia
Have a look at
http://xen.1045712.n5.nabble.com/Patches-for-Xen-VGa-Pass-Through-NVIDIA-for-staging-revision-gt-24232-td5025232.html
So you need to extract the "VGA BIOS" using nvtools.
Download Xen sources et compil in tools
rev=24354;hg clone -r $rev http://xenbits.xensource.com/staging/xen-unstable.hg/
xen-unstable.hg-rev-${rev}
cd xen-unstable.hg-rev-${rev}/tools
make -j4 && make clean
cd ..
Apply the patchs
wget -q
http://www.davidgis.fr/download/xen-4.2_rev24232_gfx-passthrough-patchs.tar.bz2
tar xjf /xen-4.2_rev24232_gfx-passthrough-patchs.tar.bz2for file in $(ls
xen-4.2_rev24232_gfx-passthrough-patchs/*);do patch -p1 < $file;done
Copy your vgabios et rename it to vgabios-pt.bin
cp <your_vgabios.rom> tools/firmware/vgabios/vgabios-pt.bin
make -j4 xen tools stubdom
make -j4 install-xen && make -j4 install-tools PYTHON_PREFIX_ARG=
&& make -j4 install-stubdom

Objet : [Xen-users] Regarding :-GPU pass through and VGA pass through
Hi,
I am using GTX480/590 Nvidia graphics card as per my discussion with
"Nvidia support team"
doesn''t support VT-d pass through for GTX480/590
I have the following query:-
1->Is GPU pass through and VGA pass through same ?
2->if different in that case can i use GPU pass through for GTX 480/590.
Thanks,
Akhilesh
