hi Weidong,
Below, you mention the FLR code
is in xen-unstable already - please could you point out where?
I thought that this code was in
pciback and now transferred to pci-stub, but I can`t seem to find it anywhere
...
Cheers,
Tim

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) [VT-D]io.c:284:d0 VT-d irq bind:
m_irq = 37 device = 3 intx = 0
(XEN) [VT-D]iommu.c:1292:d0

(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.
