  13. Xenomai is split in two parts: a kernel part and a userspace
  14. part. Enabling this option automatically selects the Xenomai
  15. package and helps in patching the Linux kernel built by
  16. Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).
  17. You can find the currently supported kernel versions by
  18. looking at the available patches in the Xenomai sources
  19. tree: ksrc/arch/$(ARCH)/patches
  20. However, it is recommended to use the latest version of the
  21. Adeos/Ipipe patch available at
  22. https://xenomai.org/downloads/ipipe/
  23. Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
  24. and PowerPC architectures.

  29. Optionally, explicitly specify where to find the Adeos
  30. patch to use.
  31. Examples:
  32. https://xenomai.org/downloads/ipipe/v4.x/arm/ipipe-core-4.19.33-arm-2.patch
  33. or /home/foo/ipipe-core-4.19.33-arm-2.patch
  34. Please verify that your kernel version in Buildroot matches.

  60. help
  61. Linux Framebuffer drivers for small TFT LCD display modules,
  62. e.g. Adafruit PiTFT displays for Raspberry Pi (this extra
  63. package is only needed for linux kernels until v3.19, since
  64. v4.0 the drivers are included in the staging area).
  65. To enable fbtft, e.g. for Adafruit 2.8 PiTFT, enable the
  66. following kernel configurations:
  67. - CONFIG_SPI
  68. - CONFIG_GPIOLIB
  69. - CONFIG_FB
  70. - CONFIG_FB_TFT
  71. - CONFIG_FB_TFT_ILI9341

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

  109. The version you choose must match that of your kernel.
  110. Usually, the sha1 of the cset you want to use; avoid using a
  111. branch name as this yields non-reproducible builds.
