Dear David Techer,

I noticed that there are FOUR memory ranges for the VGA card to be passed through.

lspci | grep VGA

01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 8400 GS] (rev a2)

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

[0.120488] pci 0000:01:00.0: reg 10: [mem 0xd2000000-0xd2ffffff]
[0.120508] pci 0000:01:00.0: reg 14: [mem 0xc0000000-0xcfffffff 64bit pref]
[0.120528] pci 0000:01:00.0: reg 1c: [mem 0xd0000000-0xd1ffffff 64bit pref]
[0.120556] pci 0000:01:00.0: reg 30: [mem 0xd3000000-0xd307ffff pref]

Why do you use only the first three memory ranges? How about the last (i.e. the fourth) memory range?

Is there a mistake in your method or blog? This is because I have realized now that my Xen VGA Passthrough is only partially successful. I can run 2D graphics benchmarks, but NOT 3D graphics benchmarks.

Please check out my Youtube video. Device Manager says that Windows 8 and XP has stopped the VGA card because it has a problem. Device manager also says that the VGA card is not using any resources because it has a problem. There is a yellow exclamation mark besides NVIDIA Geforce 8400 GS.

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)

Dear David Techer,

The command I use checks out the latest changeset, so it is not necessary to use "hg clone -r CHANGESET".

Thank you very much.

For mercurial you forgot to add the flag (-r ) from 25070 (keep in mind that your document may be used in the future)

Should be

hg clone -r 25070 http://xenbits.xen.org/xen-unstable.hg xen-unstable.hg-cs25070-vga-passthrough

and not

hg clone http://xenbits.xen.org/xen-unstable.hg xen-unstable.hg-cs25070-vga-passthrough

Have a nice week-end.

David.
