> Hi,
>
> I tried patching Xen 3.4 Testing c/s 19628 with vga passthrough code
> (less HID passthrough), and did some tests. I made some modifications in
> pci_setup to skip loading the emulated VGA bios and pci_load_option_roms
> to load the passthrough VGA bios. The setup uses Intel DQ45CB and ATI
> HD2600XT.
>
> The BDFs for the relevant devices are:
> Intel IGD  00:02.0
> ATI gfx    01:00.0, 01:00.1
> There''s 2 BDFs for ATI because one of them is for the Audio. Both
have
> to be passed through simultaneously.
>
> In the first scenario, Intel IGD is set up as the primary for Dom0. The
> ATI gfx is passed through to DomU. Interestingly, it is the screen that
> is connected to Intel''s output that displays DomU (albeit with few
> colors and low resolution). However, in the Device Manager, ATI is
> reported. I believe this is because Intel''s address space is being
> mapped, instead of ATI''s. Shutting down DomU does not return the
display
> to Dom0. The display remains at the last screen showing DomU shutting
> down. I have a clip showing the observations. However, I wasn''t
able to
> attach it. If you would like to take a look, please let me know.
>
> In the second scenario, Intel IGD is passed through to DomU. The ATI gfx
> is thus absent. However, when DomU is booted, there is an IOMMU page
> fault. This is shown in the attachment starting from Line 659.
> The system subsequently hangs. Does anyone have an explanation to
what''s
> going on in this case?
>
> So, VGA passthrough works, but is extremely flaky. Any
> comments/suggestions to correct the problems observed will be greatly
> appreciated.
>
> Thanks.

If you want the intel to work as a primary display adapter you need to
do all those thing:
  - Disable the vga in qemu
  - Copy the VGA bios in the guest
  - Map the legacy io port and MMIOs
  - Fake some value in the host bridge.

You can have a look at this patch.
http://xenbits.xen.org/gitweb?p=xenclient/ioemu-pq.git;a=blob;f=master/vga-passthrough;h=d2adba9f84a17df59b1bedc843d29433b4f1eff0;hb=HEAD

I will try to push it xen upstream when i''ll have some times.

Could you tell me if it works with a Vista guest or a linux hvm guest?

The page fault and the screen still stays on Windows issue are due to
the lack of FLR in your kernel. Doing a FLR on the graphic card before
booting and when the domain shutdown will fix those.

Thanks,
Jean

Apologies, I missed your earlier point about the FLR. I''ll try that
out.
Thanks.

Hi,

With the patch applied, I did a FLR on the card as follows:
echo -n "0000:00:02.0" > /sys/bus/pci/drivers/pciback/do_flr

The screen turned blank upon issuing the command. I was able to boot up
DomU. Shutting down DomU returns the screen to blank. Is this the
expected observation?

Thanks.

Hi Beng,

Would you please send the patch you applied on top of Xen to the list?
I think many people are interested in that.

Thanks,

The DQ45CB does not have enough PCI Express lanes to drive the IGD and a
x16 graphics card at the same time.

Subject: [Xen-devel] Experimental results for VGA passthrough

Hi,

I tried patching Xen 3.4 Testing c/s 19628 with vga passthrough code
(less HID passthrough), and did some tests. I made some modifications in
pci_setup to skip loading the emulated VGA bios and pci_load_option_roms
to load the passthrough VGA bios. My setup uses Intel DQ45CB and ATI
HD2600XT.

The BDFs for the relevant devices are:
Intel IGD  00:02.0
ATI gfx    01:00.0, 01:00.1
There''s 2 BDFs for ATI because one of them is for the Audio. Both have
to be passed through simultaneously.

In the first scenario, Intel IGD is set up as the primary for Dom0. The
ATI gfx is passed through to DomU. Interestingly, it is the screen that
is connected to Intel''s output that displays DomU (albeit with few
colors and low resolution). However, in the Device Manager, ATI is
reported. I believe this is because Intel''s address space is being
mapped, instead of ATI''s. Shutting down DomU does not return the
display
to Dom0. The display remains at the last screen showing DomU shutting
down. Except for the shutting down phase, I''ve recorded the
observations
in the first attachment.

In the second scenario, Intel IGD is passed through to DomU. The ATI gfx
is thus absent. However, when DomU is booted, there is an IOMMU page
fault. This is shown in the second attachment starting from Line 659.
The system subsequently hangs. Does anyone have an explanation to
what''s
going on in this case?

So, VGA passthrough works, but seems extremely flaky. Any
comments/suggestions to correct the problems observed will be greatly
appreciated.

Thanks.

- Beng Heng

Where did this patch come from? I plan to try using a ati card with a
windows domU this week but first I need to port this patch to 2.6.29,
before I start I want to make sure I am working with the latest
version of the patch.

didn''t mean the patch
was in Xen 3.4 testing branch. I got it from the patch queue.

Also, you mentioned earlier that we need to return some fake values to
the host bridge. Would appreciate if you could explain, or refer me to
some writeups on this. Thanks.

I noticed that Xen does not boot if only the Intel IGD is present and
selected, i.e. only one graphics device.

Also, I''m not able to get high resolution if I passthrough Intel IGD
and
install the Intel Graphics Media Accelerator driver. Ironically, I can
get higher resolution and color if I remove the driver. Has anyone
encountered similar observations before?

Perhaps I should clarify that the low resolution with Intel driver is
observed in Windows XP. It works fine in Vista. I was able to run 3DMark
on Vista.

Here''s a very concise summary of my test results.

The gfx used were
- Intel GMA 4500
- ATI Radeon HD 2600 XT
- nVidia GeForce 9500 GT

Each card is set as the primary adapter in turn, and passed through to
DomU is attempted. The respective gfx drivers are installed if DomU
manages to boot up.

Gfx     Ubuntu64        XP               Vista
------------------------------------------------------
Intel   Hang            Low Res/Color    Low Res/Color
ATI     Hang            Normal           Normal
nVidia  Blank Screen    Blank Screen     Blank Screen

Would appreciate any comments or suggestions to perhaps improve the
above situation. Thanks.

Sure. intel is like SDL or VNC, it''s another frontend driver for qemu
that render on the intel framebuffer directly.
We use that to display other vm when we gave the intel GPU to another vm.

Yes, here are the value we need to fake and the raison why:
  - GMCH, when the vgabios execute at actually check this register in
the host bridge (bdf 0:0.0, offset 0x52). On the intel platform this
register is there to identify the amount of stolen memory and
therefore the supported resolution in legacy mode (VGA/VESA).
  - VID/DID. Linux check that. If it doesn''t match with the graphic
card it doesn''t reconise the chipset and doesn''t create the
agpgart.
  - OpRegion address. Not sure about this one, but when you
shutdown/sleep vista if this value is present the driver will try to
save some information in a ACPI NVS region.

All those register are public you can find some more information about
those here:
www.intel.com/Assets/PDF/datasheet/319970.pdf
