Xen project Mailing List

Thanks for your mail. It is a real pleasure

- to see that it works for you

- to see that you can play your favorite game with such settings :). I played Crysis 2 using 1920x1080 resolution, DirectX 9

but this is the only game that I tested - single player -. I have to test as you did :) for the others games.

I' ve got the same CPU as you. Intel i5 2500 :) and a GTX 460 SE EVGA 1024.

Xen should work with a Linux domU too. I've did a few test on Ubuntu Lucid 64 bits.

You have to take care of the good version of Nvidia drivers for GTX 460to work.

I do not remember the real version but it is for driver 270.??

My last patches for Xen Staging (http://xenbits.xensource.com/staging/xen-unstable.hg) for revision >= 24332

are available at http://www.davidgis.fr/download/xen-4.2_rev24232_gfx-passthrough-patchs.tar.bz2

Thanks for the tip about audio.

Thanks for all.

Kind regards.

David

I've been able to successfully passthrough my nvidia vga card to a windowsxp
32 bit domU, using the patches provided by David in this thread.
Performances are AMAZING! I've played entire single player campaing of
Battlefield 3 at 1680x1050@ULTRA settings in domU, with NO visible lags or
artifacts. DomU is really rock solid, not a single crash. Crysis2, Fifa12,
NBA2K12 also played really well at maximum quality settings and resolutions.
Adobe Suite, Flash 11 and CUDA also works as on bare metal systems (eg using
gpu to accelerate).
I've been able to passthrough an usb controller and the integreted audio
card too.

I can swich between dom0 e domU by changing the input source of the monitor,
and using synergy to share keyboard and mouse over ssh.
At boot i bind the nvidia card to pciback in grub conf file.
Later I use pci-stub to passthrough audio and usb.
When I shutdown the domU, i can bind the audio card back to the dom0 in this
way:

echo "8086 1c20" > remove_id
echo "0000:00:1b.0" > /sys/bus/pci/drivers/pci-stub/unbind
alsa force-reload

Follows a bit of infos about my system config and hardware:

CPU: Intel i5-2500
MB: Asrock z68 EXTREME4 GEN3 (bios 1.10)
PRIMARY VGA: GIGABYTE GTX460 (GV-N460OC-1GI, rev. 1.0). (@dvi on monitor)
SECONDARY VGA: integrated intel hd3000, running gnome shell 3 in dom0
(xorg-edgers ppa) (@DP on monitor).

I just want to say thanks to every single xen developer out there, and David
for posting patched for nvidia cards. You just made my "life's dream" true.
Best Regards,
Ivo
