| 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. |

| 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. |

| 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 |

| 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). |

| select aufs5.x ). |

| 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. |
