10

ARGUMENTS

12       irq
13           the interrupt number
14
15       desc

DESCRIPTION

19       Level type interrupts are active as long as the hardware line has the
20       active level. This may require to mask the interrupt and unmask it
21       after the associated handler has acknowledged the device, so the
22       interrupt line is back to inactive.
