Hi I am new to this forum ,want to know that how does the processor timer gets recognized by Linux kernel.
There is a variable known as jiffy which stores the number of timer ticks a computer has been run and up since its boot.
Here is a link to the article that I am asking.

I am trying to generate a delay of the order of 10^-9 although the code exists on what I am asking but want to do it myself.
Here is a link to the code I am referring to if some one wants to see.
**broken link removed**
What I want to know is which register does the kernel reads to get the value of variable jiffy ? Is it random or well defined location?
