[Xen-users] Re : Re : Xen VGA Passthrough Questions

You're welcome.

Keep in mind that if you are going to upgrade BIOS for your motherboard, those values for your card may changed.

I was in this situation last time BIOS was upgraded.

It does mean that those values will changed each time you upgrade your motherboad BIOS but having thos values changed after a BIOS upgrade could occur for a specific upgrade.

Don't ask me why...I do not know.

So you will be well advised to heck those values for each BIOS upgrade.

Moreover don't waste your time to test VGA PassThrough for NVIDIA for Windows 7. For Windows 7 use ATI.

I did my tests for playing with wine 1.4/1.5 on domU Ubuntu Lucid 10.04.4 PV HVM (game like Crysis 2) and it rocks :)

My configuration:

Manufacturer: MSI / Product Name: H61MU-E35 (MS-7680)

Bios version: V10.11

Dear David Techer,

Thank you.

I think the following command is sufficient.

dmesg | grep 01:00.0 | grep "pci.*mem"

Yours sincerely,

Dear David Techer,

I have read through your article on Xen VGA passthrough on http://www.davidgis.fr.

It appears that the following command on your blog doesn't work.

dmesg | grep 01:00.0 | grep BAR

The above command shows nothing at all. Is there an alternative solution?

Thank you very much.

Yours sincerely,
