The arith, and switchtest check that your system arithmetic assembly
routines and all kind of context switches are working correctly. The arith
test runs the same routines 10000 times, and rejects the run-time which
are too high (on the ground that they probably got interrupted by a timer
interrupt). What is important is to check that the nodiv_*llimd routine
result is the same as the llimd routine, and that the llumlshft routine
result is has the same most significant bits as the llimd routine result.
The run-time results should prove that using nodiv_llimd instead of llimd
is worth the trouble, which is not the case on the machine where you are
running the tests. But using nodiv_llimd does not do much harm anyway,
given the results you get, it is not really important. Anyway, if a test
fails, xeno-test will stop immediately.
The most important part of xeno-test is to let the latency test run some
time under some load, using as much parameters as possible among the
possible options of the dohell script to get the most realistic load. So,
ideally, you should pass, -m, -s, if possible -l or else, at least -h and
a duration. See dohell --help to see what these parameters mean.

Hi everyone.
I finally boot the kernel 3.2.32 with xenomai-2.6.1 on ubuntu 12.04. Based
on the "Testing the installation" item of Installing Xenomai documentation,
I got this.
Kernel boot log:

Before I couldnt execute the xeno-test due to a problem with the version of
xenomai-runtime. Now I don't know exactly how to interpret this results.
Also the rejected stuff I get don't know the meaning and what should I have
to do to get it ok.
For instance:
signed positive operation: 0x03ffffffffffffff * 1000000000 / 33000000
inline calibration: 0x0000000000000000: 7.942 ns, rejected 0/10000
inlined llimd: 0x79364d9364d9362f: 1.584 ns, rejected 0/10000
Other doubt I have, what should I have to check before I could start
programming on Xenomai?? I'm an absolutely newbie on RT stuff and Linux, so
some insights will be appreciated.
Thank you in advance.
Sebastián.
