Romain Naour88f80b32015-03-26 23:45:15 +0100[diff] [blame]11 Xenomai is split in two parts: a kernel part and a userspace
12 part. Enabling this option automatically selects the Xenomai
13 package and helps in patching the Linux kernel built by
14 Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).

Romain Naour88f80b32015-03-26 23:45:15 +0100[diff] [blame]16 You can find the currently supported kernel versions by
17 looking at the available patches in the Xenomai sources
18 tree: ksrc/arch/$(ARCH)/patches
19
20 However, it is recommended to use the latest version of the
21 Adeos/Ipipe patch available at
22 http://download.gna.org/adeos/patches

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