This is a little out of my area, but I really don't see the point of an ACPI spec update. PCI has specified level/low and ACPI systems have worked that way for decades. Can't you just make your GIC driver aware of the fact that some of its inputs have inverters on them and are effectively active low? Then all the generic code should work just like it does on other systems. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
