	  Choose this option if you want to enable Intel GVT-g graphics

	  virtualization technology host support with integrated graphics.

	  With GVT-g, it's possible to have one integrated graphics

	  device shared by multiple VMs under different hypervisors.



	  Note that at least one hypervisor like Xen or KVM is required for

	  this driver to work, and it only supports newer device from

	  Broadwell+. For further information and setup guide, you can

	  visit: http://01.org/igvt-g.



	  Now it's just a stub to support the modifications of i915 for

	  GVT device model. It requires at least one MPT modules for Xen/KVM

	  and other components of GVT device model to work. Use it under

	  you own risk.



	  If in doubt, say "N".
