13:30:27 <rayh> rayh has joined #emc-devel
13:39:32 <rayh> working on a test to see if a HAL is up.
13:39:52 <rayh> scripts/realtime status returns the following
13:40:20 <rayh> hal_lib is loaded
13:40:21 <rayh> rtapi is loaded
13:40:21 <rayh> rtai_math is loaded
13:40:22 <rayh> rtai_sem is loaded
13:40:24 <rayh> rtai_shm is loaded
13:40:26 <rayh> rtai_fifos is loaded
13:40:28 <rayh> rtai_up is loaded
13:40:30 <rayh> rtai_hal is loaded
13:40:32 <rayh> adeos is loaded
13:41:03 <rayh> Question, are all of these required for a working HAL?
13:46:59 <cradek> remember rtai is not our only supported realtime system
13:47:18 <cradek> so the answer to that specific question is definitely no
13:47:46 <cradek> I think you could check for just hal_lib because it won't load if the right support is not available
13:48:37 <cradek> % scripts/realtime status
13:48:37 <cradek> hal_lib is loaded
13:48:37 <cradek> rtapi is loaded
13:48:37 <cradek> rtl_fifo is loaded
13:48:39 <cradek> rtl_posixio is loaded
13:48:42 <cradek> rtl_sched is loaded
13:48:44 <cradek> rtl_time is loaded
13:48:47 <cradek> mbuff is loaded
13:48:49 <cradek> rtl is loaded
13:48:52 <cradek> fwiw, this is what my system reports
13:53:19 <rayh> Okay.  I tried the hal_lib and got some confusing answers when I tried halcmd.
13:53:40 <rayh> Does rtapi sit atop hal_lib
13:53:57 <cradek> no, rtapi is between the system realtime and hal
13:54:14 <rayh> Okay.
13:54:49 <rayh> If I simply search the reply from realtime status for "not"
13:54:54 <rayh> that should do the job.
13:55:16 <cradek> realtime status should return an exit code
13:55:27 <cradek> the smarts for whether realtime is loaded and working should be in that script
13:55:48 <cradek> then you can just test the exit code
13:57:09 <cradek> bbl
13:57:28 <rayh> From a terminal, do I see exit code
14:12:51 <cradek> echo $?
14:12:58 <cradek> after running the command
14:13:09 <cradek> the script does not set it correctly
14:18:21 <rayh> darn.  for now I'll do the search.
14:19:02 <rayh> Thanks for the help.
14:19:11 <cradek> I fixed realtime status for you
14:20:00 <cradek> but I didn't test it :-)
14:20:55 <rayh> Hey thanks.
