PCI, PCI Express interrupts
Each device connected to a PCI bus or PCI Express can use up to four interrupt
signals depending on the functionality.
PCI buses use four lines named INTA to INTD, typically connected to all devices
on the bus in order to periodically balance interrupt load. An interrupt signal may
thereby be used simultaneously by multiple devices (interrupt sharing).
PCI Express devices send their interrupts through messages. The interrupts are
defined by the system design.
