The kernel has the notion of "going idle". This happens whenever there is nothing to do. The kernel will enter idle mode, and when some interrupt occurs, then idle mode is exiting. exit_idle allows for this to happen. Take a look at Documentation/timers/highres.txt. It takes advantage of being able to know when the kernel enters and exits idle mode. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
