==>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. Regards Ketan *** "I am become death, shatterer of worlds. " - Robert J.
