- Organization:
Hi all,
I have some questions about the ecos kernel.
Is the RealTimeclock::dsr called immediately after
the RealTimeclock::isr or is it scheduled by the
scheduler?
When the dsr is executed, the real-time counter is
incremented and the allarms list is checked for
allarms. If an alarm in the list expires, is it
executed immediately or is it insered into the
ready queue?
Ecos is multi-thread, so the scheduler selects the
thread to run. When does the scheduler execute this
task? (when timeslice expire? When an alarm has
expired?)
Thanks in advance
Stefano
