Subject: Q: Scheduler and need_resched
Date: Tue, 24 Sep 2002 10:47:50 +0200 [thread overview]
Message-ID: <3D9026B6.3080509@fugmann.dhs.org> (raw)
Hi.
I got a small question of what happens codevice when the quantum of a
task is expired (counter == 0 -> need_resched == 1). Of cource schedule
is invoked somehow, but from where? How is the "flow". I see from where
do_timer is called, and that it schedules a BH, but then I'm stuck.
I have a feeling that some function is called (at least) each timer
tick, which tests if schedules sould be called (a test on need_resched
amongst others). I just cannot seem to find this function.
Any pointer appriciated.
