Xenomai is split in two parts: a kernel part and a userspace

part. Enabling this option automatically selects the Xenomai

Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).

You can find the currently supported kernel versions by
|
|
|
|

looking at the available patches in the Xenomai sources
|
|
|
|
|
tree: ksrc/arch/$(ARCH)/patches
|
|
|
|
|
|
|
|
|

However, it is recommended to use the latest version of the
|
|
|
|
|
Adeos/Ipipe patch available at
|
|
|
|
|
http://download.gna.org/adeos/patches
|
|
|
|
|
|

Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
|
|
|
|
|
and PowerPC architectures.

The version you choose must match that of your kernel. Usually,
|
|
|
|
|
the sha1 of the cset you want to use; avoid using a branch name
|
|
|
|
|
as this yields non-reproducible builds.
