# IRQSpam

A module that attempts to trigger the regression between 3.2.x and 3.17.

## Compile

    ln -sf  linux

    make

## Usage

    insmod irqspam.ko

    # wait a bit

    rmmod irqspam.ko

    dmesg | grep irqspam

## What it does

When loaded, IRQSpam create a kernel thread (irqspam), which is an

infinite loop that triggers a tasklet on the current CPU. The goal

is to trigger as many soft IRQs as possible.

When unloaded, the module prints the number of spawned IRQs.
