[LEDE-DEV] Observing procd progress

[Philip Prindeville]

One thing I was wondering about was, on a headless system, but that does have an LCD display, is maybe capturing the progress of procd as it runs and displaying it on that LCD.

Looking at /var/log/messages, I see:

2017-02-12T05:49:52+00:00 Powercode kernel:    4.660666] procd: - early -
2017-02-12T05:49:52+00:00 Powercode kernel:    5.253264] procd: - watchdog -
2017-02-12T05:49:52+00:00 Powercode kernel:    5.256546] procd: - ubus -
2017-02-12T05:49:52+00:00 Powercode kernel:    5.323323] procd: - init -
2017-02-12T05:50:28+00:00 Powercode procd: - init complete -

and I see where those are generated in the procd source.

I don’t see where procd communicates (logs) it’s progress that we could attach an observer.

Maybe in q_initd_run() where the DEBUG(2, “start %s %s \n”…) happens, and in q_initd_complete() where the DEBUG(2, “stop %s %s \n”, …) happens?

Hmm… for that matter, I also don’t know where procd does a wait() or wait3() or waitpid() on the rc.d/ scripts...

I’m not sufficiently versed in procd to guess at how to go about this.

Anyone else know?

Thanks,
