The charger task relies on calc_next_state() performing a delay before
returning. My reading of the code suggests that this doesn't happen
always. For example:
When pre-charging:
if (battery_temperature(&batt_temp) == EC_SUCCESS)
return ST_CHARGING;
When discharging and capacity is low:
/* Check remaining charge % */
if (battery_state_of_charge(&capacity) == 0 && capacity < 10)
return notify_battery_low();
I would like to suggest that the code be refactored to more like:
int next_checkms = 5000; /* next time to check battery */
while (1) {
int action = ACTION_NONE;
err = get_state(&state);
if (!err) {
action = calculate_action(&state);
err = perform_action(action, &next_check_ms);
}
usleep(next_check_ms * 1000);
}
so that the delays are really clear, the state is all read at once,
there is no reliance on earlier state, and we always delay even on
error.
In the meantime, this CL inserts a mandatory 5 second delay in the
loop, which should prevent the charger task lockup.
BUG=chrome-os-partner:11285
TEST=manual
(please do this test before committing)
1. boot to kernel, see that battery can be seen
2. suspend and resume device
3. see that the charger loop does not cause an EC watchdog reset and
AP power off/reset. There should be no watchdog warning message on the
EC console.
