[PATCH 06/27] nohz: Basic full dynticks interface

2012-12-29 Thread Frederic Weisbecker
Start with a very simple interface to define full dynticks CPU: use a boot time option defined cpumask through the "full_nohz=" kernel parameter. Make sure you keep at least one CPU outside this range to handle the timekeeping. Also full_nohz= must match rcu_nocb= value. Suggested-by: Paul E.

Start with a very simple interface to define full dynticks CPU: use a boot time option defined cpumask through the full_nohz= kernel parameter. Make sure you keep at least one CPU outside this range to handle the timekeeping. Also full_nohz= must match rcu_nocb= value. Suggested-by: Paul E.
