This package contains the userspace part, which consists mainly in libraries to write userspace real-time programs that interact with the in-kernel Xenomai real-time core. For those libraries to work, you need a Xenomai-enabled kernel. This is possible in two ways: - if you compile your kernel with Buildroot, you need to go to Linux Kernel -> Linux Kernel Extensions to enable the Xenomai extension. - if you compile your kernel outside of Buildroot, you need to make sure that it is Xenomai-enabled. Finally, if you are using a static /dev, make sure to uncomment the Xenomai entries listed in target/generic/device_table_dev.txt. if BR2_PACKAGE_XENOMAI config BR2_PACKAGE_XENOMAI_VERSION string "Custom Xenomai version" help Manually select Xenomai version. If left empty, the default version will be used. Make sure that the selected version has a patch for your selected Linux kernel. If it does not, download and select a patch manually with BR2_LINUX_KERNEL_EXT_XENOMAI_ADEOS_PATCH, in the Linux Kernel -> Linux Kernel Extensions menu. choice prompt "Xenomai core" default BR2_PACKAGE_XENOMAI_MERCURY help Select the Xenomai core: dual kernel (Cobalt) or native Linux Kernel (Mercury). config BR2_PACKAGE_XENOMAI_MERCURY bool "Mercury" depends on !BR2_LINUX_KERNEL_EXT_XENOMAI help Select Mercury core for the Xenomai userspace. You want to use it if you have the native Linux Kernel. config BR2_PACKAGE_XENOMAI_COBALT bool "Cobalt" help Select Cobalt core (dual kernel) for the Xenomai userspace. Use this if you use a Xenomai-patched Linux kernel. If you want to use Cobalt core, your kernel must have the Adeos and Xenomai patches applied to it. You can add these through the BR2_LINUX_KERNEL_EXT_XENOMAI option in the Linux Kernel Extensions menu. endchoice config BR2_PACKAGE_XENOMAI_ENABLE_SMP bool "Enable SMP support" default y help This option enables SMP support in Xenomai userspace.
