Re: [Xen-users] GPU passthrough with xen 4.2.1 on ubuntu 12.10

[Peter Maloney <peter.maloney@xxxxxxxxxxxxxxxxxxxx>]

Okay that is enormous output :D

And I'm not sure what to say about it... hopefully someone else reading it can read it better than I can.

Your bridges:

00:02.0 PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 2a (rev 07)
80:02.0 PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 2a (rev 07)

Your GPUs:

So you would be fine with PCI bridges if that 80 vs 00 is really different bridges and not just same ones seen by different CPUSs.

I can look at many older Xeons and they all show just one set of bridges, and one very new one (newer socket) has the same thing as yours. But I don't use IOMMU on those, so I don't know what effect it has.

I kinda think they are the same bridge, which would be bad. I don't know how to test it... pull out a CPU? ;) find some other detail that has IDs? disable one in the bios (unlikely)? or you could test this by passing through both cards to the same domu... This would be a good test (and matches what the other thread was about... his worked with passing both through)

I'm going to try passing through both cards and see if that works as well as passing through just the one but with only one card present.  I've had a dig for the thread your talking about but I cannot find it.  If anybody else knows if it still exists somewhere I'd be grateful if you could let me know.

Thanks again for your help.

Ah, because you have 2 cpus and 2 cards, can you post output of "lspci -tv" and "lspci"? There was one guy who could pass through one card, but when he physically added the 2nd card in the machine, the same config with the first card wouldn't work any more because the 2 cards were on the same PCI bridge. And he could pass through both and have them work, but not just one of them at a time. (I have since cleaned out my email box, and so I can't find the old thread)

So you see on my system, the "02.0" bridge is separate from "0c.0", so I don't have a problem.

That was a good suggestion, I've just tried passing through a USB controller and that worked fine.  The driver installed correctly and I can use devices attached to the relevant ports.  The problem therefore seems to be to do with gpu passthrough specifically.  I'm just going to describe my system and some settings I have in the bios as this is starting to feel like a system specific problem.  The system is

Asus Z9PE-D8 WS motherboard (chipset is intel C602)
Dual Xeon 2620
64 GB non-ecc memory
Dual AMD radeon HD 7970 in slots 1 & 5 (it's the one in slot 5 I'm trying to pass through)

In the bios I have vt-d enabled.  I also have sub-feature settings for "Coherency Support" and "ATS Support" which are disabled by default.  I've tried all combinations of these enabled and disabled.  If I enable "ATS Support" I do however have to add the option "iommu=no-qinval,no-intremap" to the xen boot otherwise the system hangs as per this thread.  If the problem is to no with these options then I think I have a problem.

Has anybody got any thoughts?

Did you try other devices, such as your onboard sound card, your onboard USB controllers, etc.? Maybe your board doesn't do passthrough properly.

Or did you try another PCIe port for the card? Maybe there are bugs where the addresses overlap with some other device, but in another slot it wouldn't happen.

First of all, thank you for the suggestions.  I've now re-installed windows and I've tried driver versions 12.3, 12.8 and 13.1 all with and without the CCC as I read in various places that it can cause problems.  For 13.1 I never get anywhere close as per my previous messages.  For 12.3 and 12.8 I at least get a BSOD,

Having the windows logo freeze in the VNC window has been my experience with GPU passthrough as well.

Hi,

I believe that the Windows logo freezing in the vnc window is normal behaviour when secondary GPU passthrough is working as it should, since the display should be handed over to the GPU. At least that was the case before when I was passing through a HD6850 card as secondary to win7 using xl. But you should expect output on the GPU, of course.

Have you tried different versions of the catalyst driver? I think that some users have reported problems with the latest one (13-something).

Hi all,

I've managed to get a windows 7 x64 hvm to boot and install and I'm now looking to pass through a HD 7970 as a secondary GPU.  in order to prepare the devices for passthrough I've used

xl pci-assignable-add 83:00.0
xl pci-assignable-add 83:00.1

Where I've identified the device pci ids using lspci.  This works fine and the devices appear when I call 'xl pci-assignable-list'. After adding them to the vm config (see below) I was able to get the vm to boot and the devices appeared in device manager.  Installing the ATI drivers however has meant that on further boots the  machine never gets past the windows logo in the VNC window and no output is generated from the ATI card.  It simply freezes there and the only way I can get back into windows is via safe mode, even after uninstalling the ATI software.

Has anybody else experienced similar issues or have any advice as to how to get this to work?  I'm a bit stumped and the wiki implies that this should 'just work'.

Thank you in advance for any help.

Matt
