[Xenomai] question: scheduling3

[ali hagigat]

It seems there are some scheduling policies like RT, TP, IDLE and
SPORADIC inside Xenomai code. Is there any document to explain them?
For kernel, man page of sched_setscheduler() explains every thing
about the scheduling policies, can you add some comments to clarify
the functionality of those?
Regards

No, because FIFO, SPORADIC, round-robin and Time Partitioning are common 
in the real-time space. If you want more doc to appear in the scheduler 
documentation, just send it there for review.

As a matter of fact SCHED_FIFO, SCHED_SPORADIC, SCHED_RR are normalized
by POSIX, so, you may find all the documentation you need on the Open
Group website.

Actually, as usual, you have not read xenomai documentation, because
they are documented in the API documentation with a link to the
opengroup page explaining the scheduling policies.

So, again, please go read the documentation before asking further questions.
