+  Intel GVT-g is a technology that provides mediated device
+  passthrough for Intel GPUs (Broadwell and newer). It can
+  be used to virtualize the GPU for multiple guest virtual
+  machines, effectively providing near-native graphics performance
+  in the virtual machine and still letting your host use the
+  virtualized GPU normally.
+
+  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.
