[Xenomai-help] Benchmark for Xenomai

Hello,

I would like to know if you have a list of benchmark for the board CSB637 or
a board with an ARM9.
I want to test performances of Xenomai with API Posix and I don't know how
to begin.

Thanks

I sent a mail last week about some latencies result on the CSB637.

A starting point would be to compile Xenomai for your CSB637 board, and
run the "xeno-test" script. Among the tests run by the xeno-test script,
cyclictest uses the POSIX API and is equivalent to the native API
latency test. If you want other results than latency, I am afraid you
will have to write the tests yourself. But if you do so, we will be
pleased to add them to Xenomai.

Here is some potential source for further benchmarks:

http://www.kernel.org/pub/linux/kernel/people/dvhart/realtime/tests/

They were written for -rt Linux, but should (in theory) work for
Xenomai's POSIX skin as well (haven't looked nor tried yet) -- except
for tests that may use silly signals.

And for a little help on how to compile POSIX programs for Xenomai POSIX
skin, read:

Thanks for your answers.
I have already compiled Xenomai for the CSB637 board and run some xeno-test.
Now, I would like to write my own tests and I wanted only some ideas.
Thanks for the help on how to compile Posix programs for Xenomai because I'm
a beginner.
