Hi Weidong,
Any detailed documentation for the two tasks you
mentioned?

Per our investigation, you cannot copy VGA bios from
host 0xc0000 to guest for secondary gfx assignment. You can load it from a
file.
In addition, if you want to passthrough Nvidia G8400,
you need to 1:1 map its MMIO BARs.

Weidong
Hi,
I should probably rename the subject of this email.

Dear Beng
Heng,
I understand that you got VGA passthrough working with Intel
DQ45CB and an PCI-E x16 ATI Graphics card.
I have Intel DQ45CB and
NVIDIA Geforce 8400 GS PCI-E x16.
Could you share with me in details
how you got VGA passthrough to work with ATI PCI-E x16 when you set onboard
VGA as your primary video adapter?
Thank you.

Hi
When I boot up the computer using onboard Intel GMA
4500 as the primary VGA controller, I could still see the NVIDIA Geforce
8400 GS PCI Express x16 card in lspci.
00:02.0 VGA compatible
controller: Intel Corporation 4 Series Chipset Integrated Graphics
Controller (rev 03)
01:00.0 VGA compatible controller: nVidia Corporation

I find
that following the instructions here at Xen Wiki VtdHowTo don't
work:
Binding Devices to
pci-stub
If using pv-ops dom0, also can use pci-stub to hide
devices for assignment (example PCI device 01:00.0) * lspci -n * locate
the entry for device 01:00.0 and note down the vendor & device ID
8086:10b9 .
...
01:00.0 0200: 8086:10b9 (rev 06)
...
* then use following commands to hide it: .
echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind
When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied.
My NVIDIA graphics card is using BDF 01:00.0. When I change directory to
/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at all.
Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config, it complains about pciback but I am using paravirt-ops dom 0 kernel.
And when I tried the "xm pci-list-assignable-devices", nothing shows up.
I have already specified iommu=1 in grub.
Hope the Intel folks can assist in this matter.

Ng Beng Heng at the University of Michigan
has done it. He's using the same Intel DQ45CB as me.
