Re: [Xen-devel] VGA passthrough with Drivers does not work

["涂堂訓(Tang-Hsun Tu)" <iwantplay@xxxxxxxxx>]

Hi,
  
    For these days,

we try to enable xen detailed log and create the HVM (winxp) with VGA driver again,

and the xm dmesg shows some strange warnings as follow (when we enable vga passthrough).

It seems there are some BIOS functions do not support yet,

the int15 series looks like intel specific functions.

Do these warnings affect the VGA pass through?

Are these int functions invoked from VGA BIOS?

Thanks.

Hi,

       Thanks again.
But the screen still is black.

For more details, when I start the HVM WinXP, I can see the windows flag logo.
After this flag (entering the windows), the external monitor goes to black (no signal),
and the notebook screen goes to disordered.

Hi,

          Thanks for your reply.
I patch the source and try to start the windows XP again,
but it seems still black screen and the external monitor give a "no 
signal" message
(the notebook screen is also black screen).

      What else I can try?

Allen's patch for enabling calpella/sandybridge integreated graphics passthrough is not checked in yet. Your machine should be calpella (i5), so pls apply Allen's patch (attached) to have a try again.

Subject: [Xen-devel] VGA passthrough with Drivers does not work

Hi,

            In recent days, I try to passthrough VGA to a HVM windows XP
domain on my notebook.
There are two VGAs on the notebook, one is intel IGD (primary) and the
other is nvidia (secondary).

At first, the screen will be blank/black when I start a HVM with a
passed VGA (primary one).
After I connect a external monitor and disable GDM,
the screen (external monitor) will start to display the WinXP logo
(it seems that the passthrouh is successful),
and it is only 16-bit color in display when enters into WinXP
(it means it does not have any VGA driver).
The original screen (on notebook) still is black.

However,
when I reboot the machine after installing the VGA driver,
the screen has become black.
I also try to install driver without passthrough before,
then change the setting to the passthrought,
but it still goes to black screen.
How can I solve this problem?

By the way, I aslo have some questions.
1. Why a external monitor can display but the original (notebook screen)
does not?
2. In WinXP, I can see the bochs BIOS message when I start the HVM.
      However, in Windows7, I only see a disordered screen until enters
into Winows7.
3. If the dom0 use printk (dmesg), the screen will not be align.
      It just like print a message then the screen moves up.

Thanks!

Tang-Hsun Tu
