[Xenomai-core] About scheduling routine and xnpod_announce_tick

[Germain Olivier]

Hello

My question is about the scheduling routine:
I want to know if the function xnpod_announce_tick is called at every tick
of the timer (such I suppose because it is linked with the timer), so it
will be a good place to do some EDF scheduling stuff.

Thanks

Germain

Yes, xnpod_announce_tick() is the default handler for the real-time
timer interrupt, thus gets called on every timer event. Round-robin is
already handled inside this function.

Maybe following the cross-reference might help you finding further
information:
