Hallo,
I've been using rtai until now and decided to give xenomai (release 2.1) a
try. I followed the instructions from README.INSTALL, and everything (kernel
patching, compilation, etc.) went fine. Then I tried to run the latency test,
which failed:
-----------
/usr/xenomai/testsuite/latency $ ./run
head: `-1' option is obsolete; use `-n 1' since this will be removed in the

The same for "switch", the same if I call ./latency directly.
Is it correct that the xeno_timerbench module is required for the latency
test?
I believe that it (timerbench) is only needed for latency -t2, ICBW.
I built it as a module
I get the same result wheter or not I load the module.
Ive seen that Killed line before - but its been a while, I have no
recollection...
have you tried 'run -- ' ?
the double dash insures that the following args are passed thru the script,
(so its very unlikely to matter here, but you never know ..)
heres a chunk from xeno-test on my box.
Obviously it didnt work for you, but you can re-try the running line,
see if its different than what youre currently getting.

What am I doing wrong?

Thanks in advance and best regards,

Some (hopefully useful) information follows:
-----------
/usr/xenomai/bin $ ./xeno-info
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

/usr/src/linux $ grep -3i xeno .config

FWIW, if you enable
CONFIG_IKCONFIG=y
CONFIG_IKCONFIG_PROC=y
then the xeno-test script will run that grep (ie zgrep XENO
/proc/config.gz) for you.
there are a few additions that might be worthwhile -
zegrep -E '^CONFIG_M|PREEMPT' pc-3/.config
CONFIG_MMU=y
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_MODULE_FORCE_UNLOAD=y

# CONFIG_PREEMPT is not set
CONFIG_MICROCODE=m
CONFIG_MII=y
CONFIG_MSDOS_FS=m
CONFIG_MSDOS_PARTITION=y
CONFIG_MAGIC_SYSRQ=y
I havent made them, the CONFIG_M picks up the Machine, but is perhaps
too noisy.
THen again, MMU an MODULE_* info is useful.
