This is due to the cost of occasional timer rearming, instead of classic approach where timer is programmed to shot regularly. But, if your setup is not very latency sensitive, the overhead is most likely negligible. -- 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
