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 GeForce 8400 GS (rev
a1)

I have already compiled CONFIG_PCI_STUB=y statically into the kernel.

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.
