RE: [Xen-devel] Xen 4.0.0 first release candidate / graphics passthru

["Han, Weidong" <weidong.han@xxxxxxxxx>]

Current gfx passthrough code in Xen just supports basic gfx passthrough, that 
means it does basic necessary work for gfx passthrough, and it only supports 
discrete gfx cards. We will rebase and sent out the Intel IGD passthrough 
patches which supports to passthrough Intel IGD to guest.

I indeed also sent out some hacking patches for gfx passthrough which are 
needed for some specific gfx cards, but they are experimental and not checked 
into xen. 

Regards,
Weidong
