# handle\_untracked\_irq(9)

Simple and software-decoded IRQs.

## NAME

handle\_untracked\_irq - Simple and software-decoded IRQs.

## SYNOPSIS

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

## ARGUMENTS

*desc*

the interrupt description structure for this irq

## DESCRIPTION

Untracked interrupts are sent from a demultiplexing interrupt handler when the demultiplexer does not know which device it its multiplexed irq domain generated the interrupt. IRQ's handled through here are not subjected to stats tracking, randomness, or spurious interrupt detection.

## NOTE

Like handle\_simple\_irq, the caller is expected to handle the ack, clear, mask and unmask issues if necessary.
