I came to this understanding after recalling a fact that timer is a way to trigger rescheduling after a time slice of a task is expired. SInce we can't assume anything on which core a task is currently running, then it would be easier if we just send interrupt to all cores. Not sure if you are agree with my deduction above.... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
