Dear All,

I have made a two-part video series on VGA pass through using Xen 
virtualization and Intel VT-d. These are home-made videos so please bear 
with me :-)

Please check out my blog at 
http://teo-en-ming-aka-zhang-enming.blogspot.com/2009/09/video-presentation-on-pci-express-x16.html 
for the two-part videos and additional details.

Thank you very much for viewing.

Hi All,

I went through the history and here are the steps I took to patch xen 
3.5-unstable for VGA passthrough.

Based on Weidong's advice I checked out changeset earlier than 20144.

Initial trial without secondary gfx passthrough patch
=================================

   637  hg clone http://xenbits.xensource.com/xen-unstable.hg
   638  cd xen-unstable.hg
   639  vi tools/firmware/hvmloader/hvmloader.c
   640  hg checkout 20143
   641  cp 
~enming/intel-gfx-passthru-patches/intel-gfx-passthru-patch01.patch .
   642  patch -p1 < intel-gfx-passthru-patch01.patch
   643  make tools
   644  history
   645  cd tools/ioemu-remote/
   646  cp 
~enming/intel-gfx-passthru-patches/intel-gfx-passthru-patch02.patch .
   647  patch -p1 < intel-gfx-passthru-patch02.patch
   648  cd ..
   649  cd ..
   650  cp ~enming/intel-gfx-passthru-patches/xen-load-vbios-file.patch .
   651  patch -p1 < xen-load-vbios-file.patch
   652  cp ~enming/intel-gfx-passthru-patches/xen-vBAR-pBAR.patch .
   653  patch -p1 < xen-vBAR-pBAR.patch
   654  cd tools/ioemu-remote/
   655  cp 
~enming/intel-gfx-passthru-patches/qemu-change-for-vBAR-pBAR.patch .
   656  patch -p1 < qemu-change-for-vBAR-pBAR.patch
   657  cd ../../
   658  make clean
   659  cp ~enming/vgabios-pt.bin tools/firmware/vgabios/
   660  ls tools/firmware/vgabios/vgabios-pt.bin
   661  make xen
   662  make install-xen
   663  make tools
   664  make install-tools

In the above case, intel-gfx-passthru-patch01.patch is actually 
xen-gfx-passthrough.patch as posted by Weidong.

intel-gfx-passthru-patch02.patch is actually qemu-gfx-passthrough.patch 
as posted by Weidong.

After building and installing everything, I rebooted. When I tried to 
passthrough the nVidia Geforce 8400 GS, I got "not enough free 
resources" in Windows XP domU. This is in fact much better than my 
earlier trial when I got "device cannot start" in Windows XP domU device 
manager with the wrong approach of using onboard gma4500 graphics as 
primary and nvidia geforce 8400 gs as secondary. This time I am using 
nvidia geforce 8400 gs as the primary and nothing else as the secondary.

After Timothy Moore's suggestion, I proceeded to the next trial.

Next trial WITH secondary gfx passthrough patch
==============================

   679  cd /usr/src
   680  mv xen-unstable.hg xen-unstable.hg-20143-no-secondary-patch
   681  cp -R xen-unstable.hg-20143-no-secondary-patch xen-unstable.hg
   682  cd xen-unstable.hg
   683  history
   684  cd tools/ioemu-remote/
   685  cp 
~enming/intel-gfx-passthru-patches/qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch 
.
   686  patch -p1 < 
qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch
   687  cd ../..
   688  make clean
   689  cp ~enming/vgabios-pt.bin tools/firmware/vgabios/
   690  ls tools/firmware/vgabios/vgabios-pt.bin
   691  make xen
   692  make install-xen
   693  make tools
   694  make install-tools

At this point, I encountered an error with build.c as documented with my 
earlier postings in xen-devel mailing list.

So I applied my very own patch:

Then I checked ssdt_pm.h and ssdt_tpm.h to make sure they are correct.

   695  vi tools/firmware/hvmloader/acpi/ssdt_pm.h
   696  vi tools/firmware/hvmloader/acpi/ssdt_tpm.h
   697  make install-tools


But I still get "not enough free resources" in Win XP domU device 
manager. So apparently
the patch qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch 
doesn't affect my nvidia geforce 8400 gs passed through operations since 
I am using nvidia as primary and nothing as secondary. The secondary gfx 
patch is for cases when you have a primary for dom0 and passing through 
the secondary gfx to a HVM domU.

Dear Christian,

>Did you verify (and modify if applicable) the PCI resources as per
Weidong's comment here?
http://permalink.gmane.org/gmane.comp.emulators.xen.devel/70749

Thanks for the tip! I missed this one. I believe it should solve the "not
enough free resources" problem for my graphics card. Weidong and me are
using different nvidia graphics card. Hence I should modify the dsdt.asl
MMIO BARs entries in xen-vBAR-pBAR.patch to reflect my graphics card.

>On another topic, please don't answer to other threads to get attention and
keep threading working by replying to previous versions of your own post or
its replies (and and least for me, don't reply to my personal mail address
but just to the mailing-list)

Sorry! No problem.

Hi All,

I have solved the final problem.

Thank you Christian Tramnitz for pointing me to the missing link.

I have tested my own modifications to xen-vBAR-pBAR.patch and it works!

I reproduce part of xen-vBAR-pBAR.patch here which I modified for my nVidia
Geforce 8400 GS graphics card:

have helped me along the way.

Dear All,

Here is my latest video presentation on VGA passthrough. Please check out my
blog at http://teo-en-ming-aka-zhang-enming.blogspot.com/ or the Youtube
link at http://www.youtube.com/watch?v=1ia3IwG6tp4

The "not enough free resources" problem for nVidia Geforce 8400 GS PCI
Express x16 graphics card in earlier presentation videos:

http://www.youtube.com/watch?v=HNEiSI...<http://www.youtube.com/watch?v=HNEiSInrav0>

http://www.youtube.com/watch?v=_hOT_9...<http://www.youtube.com/watch?v=_hOT_9LIG5w>

was fixed. Device manager in Windows XP HVM domU no longer shows an
exclamation mark besides the nVidia Geforce 8400 GS graphics card. The
device is working properly and the resources tab shows the available memory
ranges.

Full VGA passthrough to Windows XP HVM guest operating system using Xen
virtualization has been realized. I am now able to run 3-D video benchmarks
on the passed through nVidia GeForce 8400 GS graphics card.

All this is possible using Xen 3.5 hypervisor with Intel supplied VGA
passthrough patches. Instead of using pvops dom0 kernel 2.6.31-rc6 which
causes Win XP domU to run slowly, I am now using pvops dom0 kernel
2.6.30-rc3.

Many thanks to Xen developers, Han Weidong and other engineers at Intel, and
also Christian Tramnitz for pointing me to the missing puzzle which helped
me in resolving the final problem.

I am now able to bootstrap Windows XP HVM domU from within Linux using Xen
virtualization and play 3D games in the Windows virtual machine. In the
past, Windows virtual machines can only see a 2D emulated/virtual display
adapter. The virtualized Windows operating systems were more palatable to
server administrators than gamers. With VGA pass through and direct hardware
access by Windows virtual machines to the graphics hardware, gamers will now
be able to play 3D games inside Windows virtual machines.

PS: I am still unable to passthrough USB devices, e.g. keyboard and mouse,
to the Windows XP HVM domU. This video is captured and rendered using the
open source kdenlive non-linear video editor. The video is taken using Canon
HV20.
