[ECOS] Preemption in Bitmap Scheduler

[Potdar Smita]

I had a question about how preemption works in the
Bitmap scheduler of eCos. Since with this scheduler,
only one thread can exist at a particular priority
level, hence timeslicing is disabled. What about
preemption? Once a thread begins executing, does it
run to completion or can it be preempted by a higher
priority thread? Does eCos handle threads created
after the system starts working? If yes, how is this
done?

Thanks in advance.
Any help is greatly appreciated.
