title: Interrupt latency in Linux
body: <p>I am trying to understand if interrupt latency in linux is dependent on kernel tick (timer).</p>
  
  <p>Interrupt latency is the time that elapses from when an interrupt is generated to when the source (code) of the interrupt is handled.</p>
  
  <p>I have followed the explanation in 
  <a href="http://www.tldp.org/LDP/tlk/dd/interrupts.html" rel="nofollow">http://www.tldp.org/LDP/tlk/dd/interrupts.html</a>
  Which relate the mechanism to "real-time clock" tick.</p>
  
  <p>Is it therefore correct to say that interrupt latency is dependent on timer tick (CONFIG_HZ), i.e. higher tick value will result in smaller interrupt latency ?</p>
