watchdog_initialize()

void px4::logger::watchdog_initialize	(	const pid_t	pid_logger_main,
		const pthread_t	writer_thread,
		watchdog_data_t &	watchdog_data
	)

Initialize the watchdog, fill in watchdog_data.

References CONFIG_MAX_TASKS, and system_load.

Referenced by px4::logger::Logger::run().

Here is the caller graph for this function:

watchdog_update()

bool px4::logger::watchdog_update

(

watchdog_data_t &

watchdog_data

)

Update the watchdog and trigger it if necessary.

It is triggered when the log writer task is in ready state for a certain period of time, but did not get scheduled. It means that most likely some other higher-prio task runs busy. When the watchdog triggers, it boosts the priority of the logger's main & writer tasks to maximum, so that they get scheduled again.

Expected to be called from IRQ context.

Parameters

watchdog_data

Returns

true if watchdog is triggered, false otherwise
