Function Documentation

void fc_soc_event_handler

(

void

)

This function is the handler called when a FC SoC Event IRQ is triggered. This function pops an event and executes the handler corresponding to the event if it set.

int32_t pi_fc_event_handler_is_free ( uint32_t  event_id )

inline

This function checks if an event handler is set for the given SoC event.

Parameters

event_id

SoC event ID.

Note

It is used to check if a UDMA channel is already allocated by a device.

void pi_fc_event_handler_set	(	uint32_t	event_id,
		pi_fc_event_handler_t	event_handler,
		void *	arg
	)

This function sets an event handler for a given SoC event.

Parameters

event_id	SoC event ID.
event_handler	SoC event handler function.
arg	Soc event handler argument.
