# handle\_level\_irq(9)

Level type irq handler

## NAME

handle\_level\_irq - Level type irq handler

## SYNOPSIS

**void handle\_level\_irq(struct irq\_desc \*** *desc***);**

## ARGUMENTS

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