Re: [Xen-users] Re : Re : [SUCCESS] Xen 4.2-unstable Changeset 25099: VGA Passthrough to Windows 8 Consumer Preview HVM domU

Dear David Techer,

I always read my emails very carefully.

But in Xen VGA Passthrough to Windows 8 Consumer Preview, Device Manager reports that "Windows has stopped this device because it has reported problems. (Code 43)" for NVIDIA Geforce 8400 GS. Device Manager also reports that "This device isn't using any resources because it has a problem.". Yellow exclamation mark for NVIDIA Geforce 8400 GS Xen VGA Passthrough to Windows 8 Consumer Preview is NOT the issue. I believe the problem has to do with VGA Card MMIO BARs 1:1 matching, i.e. the file tools/firmware/hvmloader/acpi/dsdt.asl.

David Techer and Intel Corporation engineers Zhang Xiantao, Ren Yongjie and Han Weidong and Citrix Engineer Ian Campbell:

Could you help me to check through Sections 3, 4, and 6 of my "Xen VGA Passthrough - Version 1.6.pdf" documentation to see if there are any mistakes?

Please also see the following Xen VGA Passthrough to Windows 8 Consumer Preview screenshots for Device Manager.

Thank you very much for checking through my Xen VGA Passthrough documentation.

Dear David Techer,

Could you read through my documentation "Xen VGA Passthrough - Version 1.6.pdf" to see if there are any mistakes?

The problem with the device manager yellow exclamation mark for NVIDIA Geforce 8400 GS is that I couldn't run 3d graphics benchmarks. I can only run 2d graphics benchmarks.

Thank you very much.

Yours sincerely,

Here is a quick resume

- I am not able to see your screenhosts (Error 403 Forbidden) but it doesn't matter

- There is no problem in my documentation. Moreover in http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through in section "Tested domU"

there is a table where there is a list of advised driver to use for Windows XP 32/64 or Linux 32/64

Then for

Linux

====

Driver 275.28 or driver 275.43 works very well on my Linux 64 bits (Ubuntu Lucid 10.04.4)

Windows XP

==========

You should be well-advised to install the last NVIDIA drivers for series 275.XX (275.33 or 275.50). It works!

Now If you want to install NVIDIA drivers >= 280 DON'T COMPLAIN ABOUT YOUR DEVICE MARK WITH A YELLOW MARK.

WINDOWS 8

==========

Two choices

- waiting to have a new NVIDIA driver that support your stuff

- Testing a old driver. I am not going to test any driver for you. I am not going to waste my time testing any old driver.

Big issue: testing an old driver may imply to reinstall Windows 8 from scratch. Not tested but I am pretty sure about that.

Dear Xen users, developers and David Techer,

I have just downloaded, compiled, and installed Xen 4.2-unstable Changeset 25099 with Xen VGA Passthrough patches. Xen VGA Passthrough to Windows 8 Consumer Preview HVM domU is successful. Or I should say *PARTIALLY* successful. Why? Please see the screenshots below.

David Techer, could you read through my "Xen VGA Passthrough - Version 1.5.pdf" to see if there are any mistakes, which might be causing the above-mentioned error in device manager for NVIDIA Geforce 8400 GS? I could not run 3D graphics benchmarks. I can only run 2D graphics benchmarks.

Thank you very much.

Yours sincerely,
