Re: [Xen-users] Successful PCIe Graphics VT-d Passthrough to Win32 DomU, Q35 chipset

[Daniel Kao <dkao@xxxxxxxxxxxx>]

This is great news!  I have the exact same motherboard but the PCIe slot is currently used by a PERC5/i flashed with LSI firmware for an 8x750GB RAID-5 array.

It'll be interesting to see if DXVA for PureVideo HD (e.g. GPU offloaded H264/MPEG2/VC1) and CUDA works in your Windows HVM.  If it does, I'd be tempted to pick up an nVidia 9x00 to test VDPAU (i.e. MythTV, VDR, etc.) acceleration under a VT-d domU.

Cheers,
Daniel

I am happy to announce that I have successfully (and finally!) been able to pass a PCIe graphics card via VT-d to a Windows XP HVM DomU.

 

About time!

 

Config:

-Intel Q6600 Core 2 Quad-Core, G0 stepping (I think)

-Intel DQ35JO Motherboard, Q35 Chipset, BIOS v.991 (1/9/09), VT and VT-d enabled

-nVidia 9500GT (for VT-d passthrough - DomU)

-nVidia GeForce2 MX200 (Dom0 console)

-Xen (build: xen-unstable, recent as of ~ 1/25/09 1:00AM-EST)

-Dom0: Linux-2.6.18.8-xen (via xen-unstable.hg)

-DomU: Windows XP (pro, sp3, 32-bit)

 

Once the VT-d bugs were recently corrected (thank you, xen-devel!), everything went fairly smoothly.  Still very buggy yet (its xen-unstable!), but overall it works.

 

Make sure support for the PCI-backend is compiled into the kernel (not just a module) and that you have your pciback.hide options in grub (late-binding may work, but I haven’t tried).

 

Good luck!
