-Time Interpolators
-------------------
-
-Time interpolators are a base of time calculation between timer ticks and
-allow an accurate determination of time down to the accuracy of the time
-source in nanoseconds.
-
-The architecture specific code typically provides gettimeofday and
-settimeofday under Linux. The time interpolator provides both if an arch
-defines CONFIG_TIME_INTERPOLATION. The arch still must set up timer tick
-operations and call the necessary functions to advance the clock.
-
-With the time interpolator a standardized interface exists for time
-interpolation between ticks. The provided logic is highly scalable
-and has been tested in SMP situations of up to 512 CPUs.
-
-If CONFIG_TIME_INTERPOLATION is defined then the architecture specific code
-(or the device drivers - like HPET) may register time interpolators.
-These are typically defined in the following way:
-
-static struct time_interpolator my_interpolator {
- .frequency = MY_FREQUENCY,
- .source = TIME_SOURCE_MMIO32,
- .shift = 8, /* scaling for higher accuracy */
- .drift = -1, /* Unknown drift */
- .jitter = 0 /* time source is stable */
-};
-
-void time_init(void)
-{
- ....
- /* Initialization of the timer *.
- my_interpolator.address = &my_timer;
- register_time_interpolator(&my_interpolator);
- ....
-}
-
-For more details see include/linux/timex.h and kernel/timer.c.
