Re: General Question on Scheduler

[Ketan Mukadam <ketan@iitk.ac.in>]

==>1. How does the scheduler perform a task switch i.e. where do I find the
==>exact code that performs the task switch.

The function switch_to(prev,next,prev) inside the schedule() does the context
switch. the macro is defined in asm/system.h

==>2. When does the scheduler get control so that it can perform the task
==>switch. i.e is the scheduler called from the timer interrupt or something
==>like that?

Yes scheduler is called from timer interrupt.

==>4. Does the linux kernel use the facilities provided by the processor ( I
==>think x86 has facilities for task switch ) for the task switching?

Ofcourse switching is a processor dependent work.....see the code.
