This one is spurious: if you set CONFIG_XENO_OPT_NUCLEUS to y, then it
is normal that xeno_nucleus is not compiled as a module. If you choose
xenomai nucleus to be compiled as a module, but are running on a busybox
based system, the xeno-load script does not work. Since you do not tell
us your kernel configuration, or any other detail, for that matter, we
have to guess here. But it is better to avoid using run. Just run the
binaries you are interested in directly, load any module needed when you
are told with modprobe. xeno-load and "run" scripts are going to
disappear from the 2.6 branch

The errors you have only come from the fact that the default kernel
configuration do not enable all the options which allow running all the
tests.

So, no, you have made no error. You simply did not enable some options
needed for the tests to run correctly. Fortunately, error message tell
you what to do.

No, here, simply understanding what the test does (manpages help), and
the result it gives will help you. A performance is good if it is
sufficient for what your application needs. Not knowing what your
application needs, it is hard for us to tell us whether the performances
you get are sufficient.

Because we do not own the xenomai.org.php domain, we only own xenomai.org.

enable irqbench in kernel configuration

enable klatency in kernel configuratino

enable sigtest in kernel configuration

Increase size of the kernel tasks stacks pool.
