- 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).
- 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
- https://xenomai.org/downloads/ipipe/
- Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
- and PowerPC architectures.
- config BR2_LINUX_KERNEL_EXT_XENOMAI_ADEOS_PATCH
- string "Path/URL for Adeos patch file"
- depends on BR2_LINUX_KERNEL_EXT_XENOMAI
- help
- Optionally, explicitly specify where to find the Adeos
- patch to use.
- Examples:
- https://xenomai.org/downloads/ipipe/v4.x/arm/ipipe-core-4.19.33-arm-2.patch
- or /home/foo/ipipe-core-4.19.33-arm-2.patch
- Please verify that your kernel version in Buildroot matches.
