timekeeping_forward

Name:mekeeping_forward_now - update clock to the current time* Forward the current clock to update its state since the last call to* update_wall_time(). This is useful before significant clock changes,

Proto:static void timekeeping_forward_now(struct timekeeper *tk)

Type:void

Parameter:

Type	Parameter	Name
struct timekeeper *	tk

701

cycle_now = k_clock_read - atomic clocksource read() helper* This helper is necessary to use in the read paths because, while the* seqlock ensures we don't return a bad value while structures are updated,* it doesn't protect from potential crashes

702

delta = clocksource_delta(cycle_now, cycle_last, mask)

703

cycle_last = cycle_now

704

cycle_last = cycle_now

706

xtime_nsec += delta * mult

709

xtime_nsec += arch_gettimeoffset() << shift

xtime_nsec += delta * mult
