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. config BR2_LINUX_KERNEL_EXT_XENOMAI_ADEOS_PATCH string "Path for Adeos patch file" 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. comment "xenomai needs a uClibc or glibc toolchain w/ threads" depends on BR2_PACKAGE_XENOMAI_ARCH_SUPPORTS depends on !BR2_TOOLCHAIN_HAS_THREADS || BR2_TOOLCHAIN_USES_MUSL #------------------------------------------------------------------------------- # RTAI config BR2_LINUX_KERNEL_EXT_RTAI bool "RTAI Real-time patch" select BR2_PACKAGE_RTAI help RTAI Kernel part. #------------------------------------------------------------------------------- # fbtft config BR2_LINUX_KERNEL_EXT_FBTFT bool "FB TFT drivers" select BR2_PACKAGE_FBTFT 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 https://github.com/notro/fbtft # aufs-standalone config BR2_LINUX_KERNEL_EXT_AUFS bool "Aufs Filesystem Module patch" select BR2_PACKAGE_AUFS help 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. if BR2_LINUX_KERNEL_EXT_AUFS choice bool "aufs-standalone series" help Select the major series of this version. This must match the major version of your kernel (e.g. for kernels 3.x, select aufs3.x; for kernels 4.x, select aufs4.x). Note: neither aufs1.x nor aufs2.x (both for kernels older than 3.x) are supported. config BR2_LINUX_KERNEL_EXT_AUFS_SERIES_3 bool "aufs3.x" config BR2_LINUX_KERNEL_EXT_AUFS_SERIES_4 bool "aufs4.x" endchoice config BR2_LINUX_KERNEL_EXT_AUFS_SERIES int default 3 if BR2_LINUX_KERNEL_EXT_AUFS_SERIES_3 default 4 if BR2_LINUX_KERNEL_EXT_AUFS_SERIES_4 config BR2_LINUX_KERNEL_EXT_AUFS_VERSION string "aufs-standalone version" default "" 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.
