- Xenomai Kernel part.
+ Xenomai is split in two parts: a kernel part and a userspace
+ part. Enabling this option automatically selects the Xenomai
+ package and helps in patching the Linux kernel built by
+ Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).
- In the current version of Xenomai, the following kernel
- versions are supported: on Blackfin, 2.6.34 and 2.6.36.9, on
- SH4, 2.6.32.10, on x86, 2.6.35.9, 2.6.37.6, 2.6.38.8, on

- PowerPC, 2.6.35.7, 2.6.36.4, 3.0.8.
+ You can find the currently supported kernel versions by

Optionally, explicitly specify the Adeos patch to use.

+ Download it at http://download.gna.org/adeos/patches
and verify that your kernel version in buildroot matches.
