Xen devel - Jul 2013 - Result of Applying IGD VGA Passthrough Patches to Xen 4.4-unstable Changeset 27238

Hi,

I have just applied IGD VGA Passthrough patches to Xen 4.4-unstable 
changeset 27238. Please refer to the 2 attached patches.

1. [Xen-devel] [PATCH 2/3] V4 qemu-xen-trad: Correctly expose PCH ISA 
bridge for IGD passthrough
Link: 
http://lists.xenproject.org/archives/html/xen-devel/2013-06/msg01720.html

2. [Xen-devel] [PATCH 3/3] qemu-xen-trad: IGD passthrough: Expose vendor 
specific pci cap on host bridge.
Link: 
http://lists.xenproject.org/archives/html/xen-devel/2013-02/msg00538.html

These are the steps I took to patch, compile and install Xen 
4.4-unstable changeset 27238.

cd
hg clone -r 27238 http://xenbits.xensource.com/xen-unstable.hg 
xen-unstable.hg-cs27238
cd xen-unstable.hg-cs27238
sudo -s
./configure
make world
make clean
cd tools/qemu-xen-traditional-dir-remote
patch -p1 < patch2of3.txt
patch -p1 < patch3of3.txt
cd ../..
make world
make install

However, I still encountered problems installing Intel HD Graphics 
display drivers. The driver installation would auto detect the display 
adapter, causing the LCD monitor to blink 1-2 times. But after that, the 
LCD monitor goes into Power Saving mode (blank screen) forever again. I 
tried to destroy the Windows 8 HVM domU and restart it. Windows 8 HVM 
domU would start up for a few seconds, then falls back to blank LCD 
monitor screen forever again.

Please advise.

Thank you very much.

Yours sincerely,

Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Did you try installing the driver *before* enabling IGD passthru? (if
that''s possible)

It''s not possible. The Intel HD Graphics display driver does not allow 
me to install the graphics driver without the existence of Intel HD 
Graphics 4600 IGD.

Is there any other workaround?

- Are you using qemu-traditional for sure? 
- Are there any cmdline options for the Intel driver installer to install
without the device present?
- Any errors in the Xen dmesg? How about qemu logs? dom0 dmesg?

It seems you''re not using any dom0_mem= option. 
Try configuring dom0_mem=1G or so.

Also it seems you''re not hiding the Intel IGD PCI devices.. 

Did you make sure the Intel IGD driver does not load in dom0 ?

So the Intel IGD driver is loaded here in dom0 kernel..
