[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Partial Success VGA passthrough NVIDIA GeForce 7600 GS on Intel 5520
(Sorry if this is a duplicate. I've been having email client trouble and can't tell if it is going out.)
I've been working on getting VGA passthrough to Windows 7 working on my
machine. I have already succeeded in passing through the second network
card. That worked flawlessly.
SuperMicro x8dai (5520 chipset)
GeForce 7600 GS (I'm passing this one through)
GeForce 6800
E5520 processor
I started by trying to follow everything that Mr. Teo En Ming did. I
applied qemu-change-for-vBAR-pBAR.patch,
qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch,
xen-load-vbios-file, and xen-vBAR-pBAR.patch. I applied them all by
hand since it's been so long.
I also found the message about updating xen-vBAR-pBAR.patch to have the
memory addresses from lspci -v, so I did that.

I succeeded in getting the videobios to load, and get output on the
graphics card! So, at least something works.
I still get "Windows has stopped this device because it has reported
problems. (Code 43)" and the yellow exclamation mark in the device manager.
I then installed Debian in a virtual machine, and tried to do vga
passthrough there to get better debug. When I do a "lspci" from inside
Debian, it returns

If I had to guess, I'd say the Expansion ROM isn't loaded correctly, but
I don't know where to start to fix that, or if it is even a problem.
Any ideas on what is going wrong, or how to fix it? Any help would be
appreciated.
Thanks,
Austin Schuh
