Real-Time Framework for Linux

|
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.

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.

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.

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"
