nptel lecture on cpu scheduling

Question

 

Why P1 is still running after 2ms, shouldn't P2 get the cpu burst? In the video they said that are are no processes present other than P1 when the timer interrupts after 2 time slices. Isn't the gantt chart wrong. What i am missing here, can anyone explain it right?

Comments

okk.. i think im getting it.. P1 is already there first at t=2, but i think i've seen examples like this where the other processes are scheduled first.. dont know for sure. can i ask for the source of this implementation.

And thank you so much for replying and clearing doubts.
