It contains the IRQ, the GPIO address, and the mode, same as in the
config file :). In isa_machdep.c:
* 'intr' encoding:
*
* 0x0000000f ISA IRQ#
* 0x00ff0000 GPIO port#
* 0x01000000 interrupt signal hold/through (1:hold/0:though)
* 0x02000000 interrupt detection level (1:low /0:high )
* 0x04000000 interrupt detection trigger (1:edge/0:level )
