	  Real-Time Framework for Linux
	  http://www.xenomai.org

	  Xenomai is split in two parts: a kernel part and an
	  userspace part.

	  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.

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.

	  or native Linux Kernel (Mercury).

	  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.

config BR2_PACKAGE_XENOMAI_ENABLE_SMP
	bool "Enable SMP support"
	default y
	help
	  This option enables SMP support in Xenomai userspace.

	  If this option is turned on while no SMP support is enabled
	  in the kernel, things will still work. However, if SMP is
	  enabled in the kernel but this option is not turned on,
	  Xenomai applications will complain with:

	    feature mismatch: missing="smp/nosmp"
