Hi,
I’m looking at using the default eventq (or allowing for it), in a
library I’m working on. In order to do that, I have a function:
static struct os_eventq *
sensor_mgr_evq_get(void)
{
os_eventq_ensure(&sensor_mgr.mgr_eventq, NULL);
return (sensor_mgr.mgr_eventq);
}
And this function gets called within my package’s sysinit, as I want
to schedule a callout to run this function immediately on bootup:
/**
* Initialize sensor polling callout and set it to fire on boot.
*/
os_callout_init(&sensor_mgr.mgr_wakeup_callout,
sensor_mgr_evq_get(),
sensor_mgr_wakeup_event, NULL);
os_callout_reset(&sensor_mgr.mgr_wakeup_callout, 0);
The problem is that the default event queue is not setup until after
sysinit executes, as task setup is later on.
What is the right way to do this? For now, I can move the
initialization from sysinit and to the main() function at task level,
however, I don’t think this is how we want to manage initialization
over time. We probably need some way for a package to have a system
initialization stage that runs after the OS has started, and the default
event queue has been set.
Cheers,
Sterling
