Hi Weidong,
Do you have any ideas why gfx passthrough
couldn’t work in my case?

Hi Weidong,
Thank you for all your hard work ;)
I have just successfully passed through
my Nvidia Geforce GTX260 as a fully functional card to my WinXP DomU !!!!!
My findings so far:
1) Tried with my 9500 GT (Secondary
card) which DOES load the driver successfully but NO output on the Monitor (VGA
is sized correctly but monitor is OFF)
2) GTX260 (Primary card) (Dom0 boot VGA)
starting DomU from remote SSH console, VGA Loads and Display works !!!!
In both cases I am using the NVidia
binary driver in the WinXP DomU.
The 9500GT (Secondary card) passthrough
still has issues, the driver loads without the Monitor displaying anything
(DPMS?) and if I make ANY changes to the DomU Graphics then the DomU locks up
hard.
[Weidong]: I
didn't try 9500GT. Seems it needs extra hacks.
In both cases the VGA card only works
the FIRST time, I.e. FLR is required to reset the card for re-use, display
become corrupt on second boot of DomU. Restart Dom0 and the VGA will work again
the first time DomU is started.
[Weidong]: Yes, it's not reset well. I suspect it's still
in graphics mode, so cannot display the boot messages in VGA mode. In my
experiments, WinXP guest can still boot into graphics mode,
although you cannot see booting progress.
Is there anyway we can impletement the
d3r, sbr or flr functionality that is in XCI? I would like to see if a sbr will
enable to Card to be reset.
[Weidong]: these
reset functions are already in xen-unstable, but no one can really
reset gfx. In my feeling, it needs vendor specific method to reset
it.
I would also like to debug the issue
with Secondary passthrough as it seems that this is nearly there too ...
Regards,
Tim

Dear Magee,
Any luck with the Intel vga passthrough
patches to xen 3.5-unstable on Intel DQ45CB with extra PCI-e x16 graphics card?
Are you using pvops dom 0 kernels 2.6.30-rc3 and 2.6.31-rc6?

That was the problem, thank you.
Now I’ll work on testing the gfx-passthrough patches.

I suspect you are using old hvm config
file. The device_model is changes in config file.
in old config file:
# New stuff
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
in new config file:
# Device Model to be used
device_model = 'qemu-dm'
Pls check it, and use the latest config
file to create guest.

Weidong

Subject: [Xen-devel] xen-unstable
pci passthrough
I
have not been able to passthrough any PCI devices using the latest
xen-unstable. I have a DQ45CB, and have successfully passed devices to
guests using 3.4.1.
The
latest c/s in my copy of xen-unstable is 20145. I just started playing
around with unstable yesterday, so I can’t tell you if earlier revisions
worked. I’ve tried with various dom0 kernels, the current 2.6.18.8-xen
branch, a xenified 2.6.29.6, and a pvops 2.6.31-rc6, and in every case I get
the same error. I’ve tried both putting pci= in the config file, and
hot-adding the device using xm pci-attach. In every case, the xm command
(either create or pci-attach) fails with the message “Error: Timed out waiting
for device model action”. The guests in every case are HVM guests, some
flavors of Windows, as well as the Knoppix 5.3.1 DVD.
The
relevant xm dmesg output is:
(XEN) PCI add device 00:1b.0
(XEN)
[VT-D]iommu.c:1292:d0 domain_context_unmap:PCIe: bdf = 0:1b.0
(XEN)
[VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf = 0:1b.0
(XEN)

(XEN)
[VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf = 0:1b.0
And
the messages from qemu-log:
dm-command:
hot insert pass-through pci dev
hot
add pci slot -2 exceed.
Please
let me know what else I need to supply to help resolve this problem. If I
need to enable debugging messages, let me know the best way to do this.
