MEMBERS

name

name for /proc/interrupts

startup

start up the interrupt (defaults to ->enable if NULL)

shutdown

shut down the interrupt (defaults to ->disable if NULL)

enable

enable the interrupt (defaults to chip->unmask if NULL)

disable

disable the interrupt

ack

start of a new interrupt

mask

mask an interrupt source

mask_ack

ack and mask an interrupt source

unmask

unmask an interrupt source

eoi

end of interrupt - chip level

end

end of interrupt - flow level

set_affinity

set the CPU affinity on SMP machines

retrigger

resend an IRQ to the CPU

set_type

set the flow type (IRQ_TYPE_LEVEL/etc.) of an IRQ

set_wake

enable/disable power-management wake-on of an IRQ

bus_lock

function to lock access to slow bus (i2c) chips

bus_sync_unlock

function to sync and unlock slow bus (i2c) chips

release

release function solely used by UML

typename

obsoleted by name, kept as migration helper
