timer interrupt

Hi All,

In Understanding  The Linux Kernel, 3rd edition I read that *scheduler_tick()* is invoked once every tick to perform some operations related to scheduling. I am confused here, how costly it would be to call the function after every tick? Does it really happened? If not, then how indication of process time slice exhausted(if any) comes to know??



Thanks
