+          Enabling GVT-g mediated graphics passthrough technique for Intel i915
+          based integrated graphics card. With GVT-g, it's possible to have one
+          integrated i915 device shared by multiple VMs. Performance critical
+          opterations such as apperture accesses and ring buffer operations
+          are pass-throughed to VM, with a minimal set of conflicting resources
+          (e.g. display settings) mediated by vGT driver. The benefit of vGT
+          is on both the performance, given that each VM could directly operate
+          its aperture space and submit commands like running on native, and
+          the feature completeness, given that a true GEN hardware is exposed.
