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 / tutorialsex: 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.
