You are talking about a hard realtime extension. There is already something for that, a quick googling will turn up some links: http://entitycrisis.blogspot.com/2008/10/hard-real-time-linux.html http://www.captain.at/howto-real-time-linux.php http://www.ibm.com/developerworks/linux/library/l-real-time-linux/ You don't need hard real time for mobile phone tasks, thouth: soft real time is enough for the most critical things.
