Audio Controller Passthrough to Windows HVM Guest

Audio Controller Passthrough to Windows HVM Guest

[Mr. Teo En Ming (Zhang Enming)]

Hi

I have tried to passthrough the HD audio controller on the Intel
DQ45CB motherboard using the following method but the audio device did
not show up in Win XP domU.

Are the below commands correct and sufficient?

echo "8086 3a6e" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:00:1b.0" > /sys/bus/pci/devices/0000:00:1b.0/driver/unbind
echo "0000:00:1b.0" > /sys/bus/pci/drivers/pci-stub/bind

rmmod snd_hda_intel

I am also trying to passthrough the nVidia GeForce 8400 GS PCI Express
x16 graphics card and Firewire controller to Win XP domU at the same
time.

VGA passthrough was successful but firewire and audio controller
passthrough are not working.

Hi

Has anybody passed through audio controller to HVM guests before?

I am not familiar with pci-stub, but with pciback this is what you
would do:

rmmod snd_hda_intel
echo -n "0000:00:1b.0" > /sys/bus/pci/devices/0000:00:1b.0/driver/unbind
echo -n "0000:00:1b.0" > /sys/bus/pci/drivers/pciback/new_slot
echo -n "0000:00:1b.0" > /sys/bus/pci/drivers/pciback/bind

Re: Re: Audio Controller Passthrough to Windows HVM Guest

[Mr. Teo En Ming (Zhang Enming)]

Seems to be roughly equivalent between pci-stub and pciback.

Wonders if there is any limitation with pci-stub.

For HVM, there is none.

It would be helpful if you could get more data in the guest then just
the 'disabled device', but I am quite ignorant of Windows XP and how to
do that there.

Perhaps you can install FC11 as your HVM guest and see what kind of
warnings/errors it shows up when you pass-through your audio + USB?

RE: Re: Audio Controller Passthrough to Windows HVM Guest

[Kay, Allen M]

Pci-stub and pciback are equivalent for HVM guest.  They both are used to "hide" the passthrough device from the device drivers in dom0 kernel.

[Han, Weidong]

We successfully passed through audio controller to hvm guest before (with 2.6.18 dom0), but we didn't try it for a while. 

Can you see any error messages in 'xm dmesg' or qemu log?

Weidong

2.6.18 dom0 is conventional xen using pciback and not using pvops?

RE: Re: Audio Controller Passthrough to Windows HVM Guest

[Han, Weidong]

I think it doesn't matter to use pciback or pci-stub to hide device. Seems we also tested it with pv-ops dom0. I can double check it. 

pls post the qemu log (/var/log/xen/qemu-dm-xxx.log) and output of 'xm demsg'.

Weidong

Re: Re: Audio Controller Passthrough to Windows HVM Guest

[Mr. Teo En Ming (Zhang Enming)]

Hi,

I have successfully passed through the HD audio controller on the
Intel Desktop Board DQ45CB to Windows XP Home HVM guest.

The reason it did not work earlier was because I had forgotten to
specifiy the BDF of the audio controller in the Windows XP HVM
configuration file. So the audio controller detection did not pop up
in Windows.

After specifying the BDF of the audio controller in the HVM config, I
downloaded the SoundMAX audio driver from the official Intel website
and installed it. After a reboot, I finally have sound in my Windows
XP virtual machine.

I will post more details later on.
