Folks,
This is my first day with Leogs. I just installed Legos,
compiled a program and have run it successfully. Haven't
got a chance to take a look at the kernel source.
I have the following questions and any response will
be greatly appreciated.
1. Is the time-slicing always on? I assume it is. If yes,
can one turn it off without actually changing the kernel
source.
2. What is the time-slice size? (10ms, 100ms ....)
3. How many threads Legos can support?
4. Can more than one thread have same priority with
stable behavior?
5. Are wait_event(), RELEASED(), PRESSED() all these
functions do busy-waiting? i.e. do they continuously
monitor the relevant inputs without yielding the
CPU to the scheduler. Or there is an interrupt type
mechanism that wakes a thread up which is waiting on
a wait_event() call.
Thanks,
- Subir
