- 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.

- 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.

- Linux Framebuffer drivers for small TFT LCD display modules,

- package is only needed for linux kernels until v3.19, since
- v4.0 the drivers are included in the staging area).
- To enable fbtft, e.g. for Adafruit 2.8 PiTFT, enable the
- following kernel configurations:
- - CONFIG_SPI
- - CONFIG_GPIOLIB
- - CONFIG_FB
- - CONFIG_FB_TFT
- - CONFIG_FB_TFT_ILI9341

- Aufs is split in two parts: a kernel part and a userspace
- part. Enabling this option automatically selects the aufs
- standalone (module) package and patches the Linux kernel
- built by Buildroot with the aufs kernel part (ie fs/aufs).
- It is important to use the correct branch of aufs-standalone.

- help
- 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.
- See the following resources to see what versions are
- available:
- For aufs3.x:
- https://sourceforge.net/p/aufs/aufs3-standalone/ref/master/branches/
- For aufs4.x:
- https://github.com/sfjro/aufs4-standalone/branches/all
