u64 clockevent_delta2ns	(	unsigned long	latch,
		struct clock_event_device *	evt
	)

clockevents_delta2ns - Convert a latch value (device ticks) to nanoseconds : value to convert : pointer to clock event device descriptor

Math helper, returns latch value converted to nanoseconds (bound checked)

Definition at line 40 of file clockevents.c.

void clockevents_config	(	struct clock_event_device *	dev,
		u32	freq
	)

Definition at line 300 of file clockevents.c.

void clockevents_config_and_register	(	struct clock_event_device *	dev,
		u32	freq,
		unsigned long	min_delta,
		unsigned long	max_delta
	)

clockevents_config_and_register - Configure and register a clock event device : device to register : The clock frequency : The minimum clock ticks to program in oneshot mode : The maximum clock ticks to program in oneshot mode

min/max_delta can be 0 for devices which do not support oneshot mode.

Definition at line 333 of file clockevents.c.

void clockevents_exchange_device	(	struct clock_event_device *	old,
		struct clock_event_device *	new
	)

clockevents_exchange_device - release and request clock devices : device to release (can be NULL) : device to request (can be NULL)

Called from the notifier chain. clockevents_lock is held already

Definition at line 377 of file clockevents.c.

void clockevents_handle_noop ( struct clock_event_device * dev )

Definition at line 366 of file clockevents.c.

int clockevents_program_event	(	struct clock_event_device *	dev,
		ktime_t	expires,
		bool	force
	)

clockevents_program_event - Reprogram the clock event device. : device to program : absolute expiry time (monotonic clock) : program minimum delay if expires can not be set

Returns 0 on success, -ETIME when the event is in the past.

Definition at line 201 of file clockevents.c.

void clockevents_register_device ( struct clock_event_device * dev )

clockevents_register_device - register a clock event device : device to register

Definition at line 280 of file clockevents.c.

int clockevents_register_notifier ( struct notifier_block * nb )

clockevents_register_notifier - register a clock events change listener

Definition at line 238 of file clockevents.c.

void clockevents_resume ( void )

clockevents_resume - resume clock devices

Definition at line 415 of file clockevents.c.

void clockevents_set_mode	(	struct clock_event_device *	dev,
		enum clock_event_mode	mode
	)

clockevents_set_mode - set the operating mode of a clock event device : device to modify : new mode

Must be called with interrupts disabled !

Definition at line 66 of file clockevents.c.

void clockevents_shutdown ( struct clock_event_device * dev )

clockevents_shutdown - shutdown the device and clear next_event : device to shutdown

Definition at line 90 of file clockevents.c.

void clockevents_suspend ( void )

clockevents_suspend - suspend clock devices

Definition at line 403 of file clockevents.c.

int clockevents_update_freq	(	struct clock_event_device *	dev,
		u32	freq
	)

clockevents_update_freq - Update frequency and reprogram a clock event device. : device to modify : new device frequency

Reconfigure and reprogram a clock event device in oneshot mode. Must be called on the cpu for which the device delivers per cpu timer events with interrupts disabled! Returns 0 on success, -ETIME when the event is in the past.
