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. comment "xenomai needs a toolchain w/ threads" depends on BR2_i386 || BR2_x86_64 || BR2_arm || \ BR2_bfin || BR2_powerpc || BR2_sh4 depends on !BR2_TOOLCHAIN_HAS_THREADS config BR2_LINUX_KERNEL_EXT_XENOMAI_ADEOS_PATCH depends on BR2_LINUX_KERNEL_EXT_XENOMAI string "Path for Adeos patch file" 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. # 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 endmenu
