[Xenomai-help] still verification problems

[Joachim Meyer]

Hi

I still have problems with 2 tests of the testsuite:
irqloop doesn't seem to work:
-------------------------------------
bash-3.00# irqbench/irqloop
Test mode:    user-space task
Port type:    serial
Port address: 0x3f8
Port IRQ:     4

Received IRQs:     0
Acknowledged IRQs: 0
bash-3.00# 
------------------------------------

latency in kernel mode fails
-----------------------------------
bash-3.00# latency/latency -t1
== Sampling period: 100 us
== Test mode: in-kernel periodic task
== All results in microseconds
latency: failed to start in-kernel timer benchmark, code -25
---|------------|------------|------------|--------|-------------------------
RTS|  267928.028|  805352.732|      32.768|       0|    00:00:40/00:00:40
bash-3.00# 
-----------------------------------------------------------------------------------

if nobody can give me hints (modules are loaded) where to look for the errors, maybe somebody can
send me the manpages. I heard they are availible for debian unstable users, but
I would have to download and in stall it, just for this reason, so maybe someone
can manage to download and send them to me.

Can I assume, if all the tests in the testsuite work, that everything works fine? Sure there won't be a
100% guarantee, but I would do anything to make sure, that later errors won't have there source in
an non working Linux/Xenomai.

Thx & Greez
Joachim

Hm, irqloop is from the irqbench test suite requiring a special setup
and does not make sense on non X86 systems: See

http://www.rts.uni-hannover.de/xenomai/lxr/source/doc/txt/irqbench.txt

You can find the error codes here:

http://www.xenomai.org/index.php/Resolving_Error_Codes
http://lxr.linux.no/linux/include/asm-generic/errno-base.h
http://lxr.linux.no/linux/include/asm-generic/errno.h

Most likely the corresponding driver modules for timer testing is not
loaded or linked into the kernel.

It's at least a good sign.

As a novice, you should not care yourself about loading modules. You
should use the "run" scripts which will take care of loading only the
proper modules, and this should work.

So, the proper way of running the latency test with the -t 1 parameter is:
cd /usr/xenomai/share/xenomai/testuite/latency
./run -- -t 1

Xenomai sources are publically accessible through svn, help yourself:
