[Xen-devel] [PATCH][VTD][GRAPHICS] enabling IGD passthrough for Calpella and Sandybridge



This patch enables IGD passthrough for Calpella and Sandybridge platforms.  To minimize impact of these changes, it checks for vendor_id of 0x8086 before creating another PCH device in the virtual platform.  For opregion, it checks both vendor_ID of 0x8086 and a non-zero PCI opregion value on device 0:2.0 before mapping the opregion.
