Chuck Zmudzinski c0e86b7624 xen/pass-through: don't create needless register group ... Currently we are creating a register group for the Intel IGD OpRegion for every device we pass through, but the XEN_PCI_INTEL_OPREGION register group is only valid for an Intel IGD. Add a check to make sure the device is an Intel IGD and a check that the administrator has enabled gfx_passthru in the xl domain configuration. Require both checks to be true before creating the register group. Use the existing is_igd_vga_passthrough() function to check for a graphics device from any vendor and that the administrator enabled gfx_passthru in the xl domain configuration, but further require that the vendor be Intel, because only Intel IGD devices have an Intel OpRegion. These are the same checks hvmloader and libxl do to determine if the Intel OpRegion needs to be mapped into the guest's memory. Also, move the comment about trapping 0xfc for the Intel OpRegion where it belongs after applying this patch.
