[Xenomai-help] rt_intr_create returns ENOSYS ?

[Hannes Mayer]

Hi all!

Subject basically says it.

I'm trying to do this:
err = rt_intr_create(&intr_desc, "parint", PARPORTINT, I_PROPAGATE);
in main() before spawning an RT tasks, but it fails with ENOSYS.
Xeno2.2, 2.4.32

Any enlightenment very much appreciated!

Thanks a lot,
Hannes.

CONFIG_XENO_OPT_NATIVE_INTR? It's default off now.

Yeah, works. Thanks! :-)

What's the reason for defaulting to off ?
Force users to write RTDM stuff ?

Tanti saluti,
Hannes.

No one is forced. We only kindly remind the user to think about the
design decision. :) (and for all others this removes unused code)

One day we will have RTDM services in user space as well. Then this
decision will be even simpler, I'm sure.

This gives a strong hint about what would be a good design decision when
crafting a device driver over Xenomai: i.e. use RTDM.

Absolutely, but if one just wants to capture the parallel
port int, I think it's a little overkill to make a driver
for it.

Anyway, is that documented somewhere, that
CONFIG_XENO_OPT_NATIVE_INTR is default off now and that
folks should preferably make RTDM drivers now ?
I'd suggest to add that somewhere...

Tanti saluti,
Hannes.

It's already present in OPT_NATIVE_INTR's help section for 2.6, but this
is missing for 2.4 (no Xenomai help strings available with 2.4
actually).
