Hardware may provide some clock source devices. When a processor sleeps and its local timer stopped, there must be additional clock source device that will handle awakening of a processor. The Linux kernel uses these `special` clock source devices which can raise an interrupt at a specified time. We already know that such timers called `clock events` devices in the Linux kernel. Besides `clock events` devices. Actually, each processor in the system has its own local timer which is programmed to issue interrupt at the time of the next deferred task. Also these timers can be programmed to do a periodical job, like updating `jiffies` and etc. These timers represented by the `tick_device` structure in the Linux kernel. This structure defined in the [kernel/time/tick-sched.h](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/kernel/time/tick-sched.h) header file and looks:
