I'm still kind of reluctant about this - doing the blacklisting here means that there's no way for a native driver to inhibit registration from occuring until after opregion setup has taken place, and we found that that was necessary on some 915 so I suspect it is on gma500 as well. Perhaps it should just be done as a module option, and then distributions who want to deal with this case could set it by default? > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_0) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_1) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_2) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_3) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_4) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_5) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_6) }, > + { PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_MRST_VGA_7) }, Moorestown doesn't have ACPI, so I don't think there's any need to include these. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
