This prog has been running for atleast 1/2 hr, with minimum args.. what should it be doing ?This is a regression test. You should see an error message or a system crash if something goes wrong. The output above looks ok (number of passed loops, kind of lifesign).
OK thanks.
FWIW, I noted that xeno-test is not running these:
- switchbench
- switchtest
- irqbench
Im not sure they belong in xeno-test though, since they dont
appear to produce output that shows good vs bad performance,
only an informal 'sanity' check.
And technically, dont regression tests have to yield
a PASS / FAIL decision ? ;-)
Speaking more broadly, there are 3 possible kinds of test-progs
- regression tests
PASS / FAIL - either by exit(rc),
or by printf( "%s\n", rc ? "not-ok" : "ok")
see perl's regression test suite ( 100k separate tests )
usually test details, are not tutorial
- performance tests
progs stress xenomai, print performance data
should help see performance problems, expose bugs
xeno-test aims to collect performance data
performance data must be expressive
(switchtest is perhaps insufficient here)
- examples / tutorials
ex: satch.c
simple, clear progs (low feature clutter, etc)
Id like to see all demo/**/ progs in single dir
forex satch-native, satch-vxworks, etc ..
makes for easier browsing
simple makefile
builds out-of-tree
handles kernel-modules and user-progs
(Ive seen some clean ones, cant find now. Mine are crufty:-(
'patterns' of usage
IWBGreat if we had common usage patterns isolated,
named, and described
Towards this last item, Ive done 2 things:
- poached code from Hannes Mayer :-)
http://www.captain.at/xenomai.php
task-timers.c does periodic timer 3 ways:
sleeper, waiter, alarm.
- scrounged old rtai/fusion code (ls -l says Jul 05 ;-)
cleaned up, 1/2 compile now
maybe theres examples-tutorials-patterns fodder in here.
attached tarball has these in 2 top-level dirs.
Id like to see if theres a place for them long-term, and clean
them up so theyre correct and helpful.
