Do you have a patch for secondary passthru on Xen 4? I seem to recall
No, we won't push this support in Xen 4, because it still needs more
thinking about secondary gfx passthru usage and implementation.
somebody had been successful with secondary passthru using an
additional patch but I cannot find it.
You can search subject "graphics passthrough with VT-d" in xen-devel
mailing list. There are lots of discussion in the thread. I attached the
mail which contains the patches for secondary gfx passthrough with some
other hacks. You can have a try with them.

I'd like to give it a try, I have one system with 2 x radeon x1950's
and another with Quadro FX380 and GeForce 9500 GT, both currently
running X, xen 3.4.2 with 2.6.31.12 suse patched dom0.

Thanks for updating those patches to current xen.
Is IGD pass-through also supposed to work when the IGD is not the
primary gfx card?
Best regards,
Christian
