Re: [Xen-devel] FLR Patch for Xen 4.0

Hi, all

I am trying to passthrough VGA in Xen4.0. My domU is windowsXP.
My graphic card is:

01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3450

I have assigned graphic card to my domU in hvm config file.

pci = [ '01:00.0' ]

I also specified gfx_passthru=2

When I create my WindowsXP domU, my computer reboots but no any display on the screen. I cannot switch to any ttys. However, I can press Ctrl+Alt+Del to restart my computer.

So I guess that my windows domU maybe start, but because of error on VGA Passthrough I can see it. That is to say, if I change a new graphic card, which supported by xen4.0, I can start my windows DomU correctly.

I give my xm info and log (qemu-dm-WinXP_HVMDomain.log, xend.log, xend-debug.log) blew. Can you give me some suggestion on the exact reasons? Is my guess right?

Thank you very much.

I didn’t try it recently. I think it should still work.

Hi,

Have you test the nVidia Geforce 8400 GS PCI Express x16 in xen4.0, which Mr. Teo Enming have test in xen 3.5-unstable branch wich some patch.

http://lists.xensource.com/archives/html/xen-devel/2009-08/msg01013.html

Thanks a lot!

2010/5/10 Han, Weidong <weidong.han@xxxxxxxxx>

If the device doesn’t support FLR capability, there will be a default reset for it, e.g. Dstate transition. But it doesn’t guarantee to work. For your ATI card, we didn’t try with it. Likely it cannot work. nVidia Quadro FX 3800 and IGD on Intel platforms (e.g. Q35 and Q45) were tested and works on current Xen upstream. Some other gfx cards may work with extra patches (e.g. 1:1 map vBAR and pBAR). There were many emails to discuss it in xen-devel mailing list, you’d better to find and read those emails.

Regards,

Weidong

My VGA hardware is as following. Can I find a patch to make it support pci passthrough?

#lspci
……
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3450

Xen4.0 can not support the ATI adapters defaultly, is it? Because my VGA passthrough can not work correctly.

2010/5/10 Han, Weidong <weidong.han@xxxxxxxxx>

There were several patches checked into xen for pci passthru, you can find relevant code in tools/python/xen/xend/server/pciif.py.
