/dev/rtc <-> scheduler

Hi,

I am working in 10 msec tick, and run separate task with the /dev/rtc that operate in 1/1024 sec

(about 1 msec).

I see that the RTC task is activated every 1 msec (as expected).

Can anybody explain how the scheduler is activated each 1 msec, although the minimal time

slice is 10 msec.

What I am looking for is the exact function/mechanism that causes this high frequency scheduling (the function I am looking for is called from the IRQ 8 interrupt handler, but what is it????)

Sincerely

Shai Lifshitz
