Add xenomai real-time Framework to buildroot
[Fixes by Thomas, including comments from Arnout:
* Use AUTOTARGETS instead of GENTARGETS
* Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the
prepare-kernel.sh script. This allows the arch name to be fixed
with the usual sed expressions and the quotes to be stripped.
* Add the --verbose option to prepare-kernel.sh. This allows to get
some clear error message when no Xenomai patch has been found for
the current kernel version.
* Improve the help texts as suggested by Arnout, and remove the
now useless README file.
* Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the
kernel configuration to find out whether SMP is enabled or
not. This cannot work because: 1) the kernel might be built
outside of Buildroot and 2) if the kernel is built inside
Buildroot, it is built *after* Xenomai, so the kernel
configuration file is typically not yet present.
* Simplify the ARM subarchitecture selection as suggested by Arnout.
* Remove the documentation and development files according to
Buildroot standards (using BR2_HAVE_DOCUMENTATION and
BR2_HAVE_DEVFILES).
* Simplify the /etc/ld.so.conf modification logic.

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.
