Re: [Xen-devel] IGD passthrough
I checked IGD passthrough with native driver on other notebook i5-540 cpu. Win7 64 driver works and which make me happy and confuse. I don't know the name of second notebook, it was provided us by our partners.At least both notebooks have the same CPUs.
Thank you for your advice.

Thank you, Allen for your replay.
I'll try to check this on other hardware.
As for Win7-64. It looks differently how IGD works. I mean when driver starts, I could recognize the windows' greeting and login. But the point is that the display is not normal, not usual. It looks like the brightness is so low, that I could hardly recognize what is output on the screen.
Attached qemu's log for win7.

Sergy,
I noticed you are using WinXP guest. Have you tried Win7-64 guest? Do you have another Calpella laptop (i.e. Thinkpad T41) to try on?
It would be interesting to know if this problem is WinXP specific or HP 8440p specific. I know there are there are quite a bit of difference between XP and Win7 IGD driver.
I have ready access to ThinkPad and Dell Calepella laptop.

Hello, everybody!
I've got an issue concerning IGD passthrough on calpella/sandybridge platform.
The IGD have passthrough-ed well on Win7 and WinXp until I setup native driver for GPU.
After installing drivers and rebooting domain the display got black when driver starts.
I found the similar issue

Could you provide any advice to make graphic works?
My system:
Hardware : EliteBook 8440p
Xen - xen-4.1.0-rc6
Linux 2.6.32.7
Sergey.
