/// ACPI represents all wired interrupts as "flat" values known as global system interrupts (GSIVs).
///
/// On ARM-based systems the Generic Interrupt Controller (GIC) manages interrupts on the system. Each interrupt is identified in the GIC by an interrupt identifier (INTID).
/// ACPI GSIVs map one to one to GIC INTIDs for peripheral interrupts, whether shared (SPI) or private (PPI).
/// The GIC distributor structure describes the GIC distributor to the OS. One, and only one, GIC distributor structure must be present in the MADT for an ARM based system.
