I mean: this is not implied, and you don't need _RT (actually, to have it,
you would need a specific interrupt pipeline patch).
Thanks for replying.
I read that this patch allows nearly all of the kernel to be
preempted, with the exception of a few very small regions of code
("raw_spinlock critical regions"), can you please point out a few
cases in which actually we "should" apply this patch?
Xenomai already gives a hard real time, so why would we need this
patch? Any hints please?
This is a different approach to a same problem:
- _RT attempts to make the whole regular kernel real-time aware.
- Xenomai 2.x provides a co-kernel for exclusively handling real-time
processing.
There are pros and cons in the two approaches, this is basically why
Xenomai 3 will allow both.
