Greetings,
From "Life with Adeos":

Both the realtime nucleus and the Linux kernel should handle the
case where a high priority thread is kept from running because a low
priority one holds a contended resource> for a possibly unbounded
amount of time. Xenomai provides this support, but only the
PREEMPT_RT variant does so for the Linux kernel. For this reason,
Xenomai keeps an
eye and provides support for the current developments of PREEMPT_RT,
albeit the mainline kernel still remains the system of reference for
now.
I don't understand whether the above quote implies that it necessary
to apply the PREEMPT_RT patch (to Linux) when working with Xenomai on
Linux?
Please guide.
No.
I mean: this is not implied, and you don't need _RT (actually, to have
it, you would need a specific interrupt pipeline patch).
