I''d be very interested to know what Bios version you are using, what your ''xm dmesg'' and ''xm info'' output is (after boot), and the xen configuration file for your VM. Cause although my system can boot fine with enabled iommu now, it is simply switched off by xen at boottime... Did you do something special to force it to on? Do you have any patches installed? Btw, passthrough of a tuner device to a pvm domU is not a problem here, but that does not require VT-d (nor VT-x). Did you manage to passthrough a device to Windows? My ultimate goal is to passthrough a (secondary) usb card, and a (secondary) graphics card, to a Windows hvm.

From your xm dmesg, and xm info, it is clear that iommu is indeed enabled for you, something which i''ve not been able to achieve with my board. Could the CPU make a difference here? I''m on a i5 750, and notice you are using an i7 860.... I''ll see if i can do some more experiments with my setup, perhaps switching back a few changesets to 4.0-rc8. I''m not sure if the kernel makes a difference, but i''ll see if i can match your configuration as close as possible. Thanks for your input!

Hi, The last few days i played some more with the vt-d feature enabled on my system, I''m now able to passthrough an usb controller to a windows xp hvm. When i plug a usb drive into a slot controlled by that controller, windows behaves as expected. Passing through a hda-intel device (from my graphics card) seems to at least be recognised properly by windows, and windows is able to install the driver (can''t verify that it is actually playing audio, since the graphics card itself can''t be passed through yet, and thus the connected monitor is in standby). So as far as i can tell, vt-d is working fine now on this system. Passthrough of the secondary graphics card to windows, doesn''t seem to work (well, i guess that''s to be expected at this stage, since i''ve only tried passing it through as a normal pci card, and i think it needs an extra flag set in the config and some patches in xen, as well as passing along a bios file). Strange thing i noticed though, when i try to boot windows with the secondary graphics card listed in its pci section, my primary X session will reset, and i''m presented the gdm login screen... (primary & secondary graphics card are both hd4350). Another strange thing i noticed, is that when i kill windows using xm shutdown (since it won''t boot with the graphics card listed), i am not able to start it again later, not even after removing the pci devices from the config. Only after a machine reboot, things will work normal again. Next on my list: try passthrough of the primary graphics card...

I had no problems passing through my Nvidia 8800gts 512. The nv driver
on linux works fine (as good as it can). There were a few quirks to
note, but I imagine your experience will vary using ATI.
- It takes a bit before you see VGA output
- The cursor was positioned a higher than normal (sitting at over the
halfway mark for the font)
- Shutdown of Xorg can leave you with a blank console
- Shutdown then Restart of domU without restarting dom0 may lead to no
VGA output, however you can still ssh in and startx (Xorg) and it will
produce output
This is my specific dom0 grub2 entry for VGA passthrough
menuentry "Xen 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.10-xen2 pvops IOMMU
SERIAL" {
insmod ext2
search --no-floppy --fs-uuid --set 321dedfa-be48-4b4d-bff0-0e5ecce240fd
multiboot /boot/xen-4.0.0-rc8.gz dummy=dummy iommu=1 dom0_mem=1024M
com1=19200,8n1,0xe480,17 console=com1
module /boot/vmlinuz-2.6.32.10-xen2 dummy=dummy root=/dev/sdc2 ro
xen-pciback.permissive xen-pciback.hide=(01:00.0)(00:1a.0)(00:1d.0)
console=hvc0
module /boot/initrd.img-2.6.32.10-xen2
}
A couple of those addresses are the usb controllers so I make use of
mouse and keyboard. I never could get qemu passthrough to work. Epic
fail on trying to use the nvidia drivers =) The new version tells you
specifically that it does not support the card @ PCI xxxx
All I needed in the hvm config was:
gfx_passthru=1
pci=[''01:00.0'',''00:1a.0'',''00:1d.0'']
I can''t think of anything else right now :)

- Did you passthru all the PCI IDs or just one?
I''m only aware of one ID -> xen-pciback.hide=(01:00.0)
- Was it primary or secondary graphics adapter?
primary
- Motherboard vendor/model and BIOS version/CPU version
Asus P7P55D Evo
bios 1207 (old)
core i7 860
- How did it work.. did you have some issues?
the nv driver on linux works fine (as good as it can)
it takes a bit before you see VGA output on boot
the console cursor was positioned higher than normal (sitting at over
the halfway mark for the font)
shutdown of Xorg can leave you with a blank console
shutdown then Restart of domU without restarting dom0 may lead to no VGA
output, however you can still ssh in and startx (Xorg) and it will
produce output

Were the patches for secondary passthrough applied to xen-unstable? Are they available so as to be applied manually to xen-unstable tip?

And FLR seems really not to work because the part from the original mail says:> shutdown of Xorg can leave you with a blank console > shutdown then Restart of domU without restarting dom0 may lead to no VGA > output, however you can still ssh in and startx (Xorg) and it will > produce outputAnd as he wrote:> it takes a bit before you see VGA output on bootI had the same effect. I first saw the linux kernel boot messages, nothing from BIOS or grub but X11 works fine. I think the cause is that BIOS and grub are using INT10 (but VGA-BIOS is not working right). Later linux kernel and X11 are using direct card access. X11 works but when I start Windows XP no graphic output!

I noticed a message: pciback pci-1-0: 22 Couldn''t locate PCI device (0000:01:00.0)! perhaps already in-use? Maybe this is because I''m doing all of this from script and immediately starting the hvm. Could use a delay? I also patched in load BIOS from file and results were the same The only thing *new* that I''ve noticed is that when power saving/screen blank occurred on console, mouse/keyboard (usb controllers passed through per above) movement from domU would not wake it up. I thought perhaps it was actually coming in from setterm on dom0. If this is the case I assume setterm -blank 0 -powersave off -powerdown 0 may handle that. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Hi, Since vt-d seems to work ok now on my system, i have been tinkering with the VGA passthrough today, and alas, got it to work for my windows hvm! - Xen version used: 4.0.0 - Dom0 kernel version: pvops from xen/stable-2.6.32.x branch - lspci for the graphcis card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.

I passed the graphics, and the audio pci ids both to the hvm. I also passed an usb card pci id. - Was it primary or secondary graphics adapter? It was the primary adapter. I tried the secondary as well, but could not get it to work. - Motherboard vendor/model and BIOS version/CPU version Asus P7P55D-Evo Bios 1307 (latest) Core i7 860 - How did it work.. did you have some issues? After i installed the catalyst driver, and XP rebooted, the graphics login screen for XP appeared on the monitor (after some time). I did not see any boot messages though... _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
