[yocto] Embedded Linux with Xenomai support

[Asier]

Thank you for all your answers.

As Robert Berger wrote, Xenomai is a patch that you need to apply to the
kernel and then compile it. I haven't done it yet, but I think there might
be some difficulty if patching an already patched kernel. Is this the case
in the Yocto distributions?

Building the userland stuff may also be quite ardous.

I want hard real-time. Really, it might be enough with soft real-time, but
I don't want to take the risk. The real-time system has a 1ms period.

Wolfgang, do you plan to support x86 architecture?

I'll ask Denx, as well as Wind River and Enea about Xenomai and x86 support
for their Linux distributions. If I get through something, I'll let you
know.

Best regards,

Asier
