Interrupt Pins, "Interrupts on PCI are optional and defined as level sensitive, asserted low), which means that the interrupt output of PCI devices plugged into PCI-to-to PCI bridges of Loongson chipset will be also converted to high-level. So high level triggered type is required to be passed to acpi_register_gsi() when creating mappings for PCI devices.
