- 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
- http://download.gna.org/adeos/patches
- Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
- and PowerPC architectures.

- depends on BR2_LINUX_KERNEL_EXT_XENOMAI
- help
- 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.

- help
- Linux Framebuffer drivers for small TFT LCD display modules,
- e.g. Adafruit PiTFT displays for Raspberry Pi (this extra
- 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
