NAME

       hrtimer_start_range_ns - (re)start an hrtimer on the current CPU

SYNOPSIS

       int hrtimer_start_range_ns(struct hrtimer * timer, ktime_t tim, unsigned long delta_ns, const enum hrtimer_mode mode);

ARGUMENTS

       timer
	   the timer to be added

       tim
	   expiry time

       delta_ns
	   "slack" range for the timer

       mode
	   expiry mode: absolute (HRTIMER_ABS) or relative (HRTIMER_REL)

RETURNS

       0 on success 1 when the timer was active

NAME

       schedule_hrtimeout_range - sleep until timeout

SYNOPSIS

       int __sched schedule_hrtimeout_range(ktime_t * expires, unsigned long delta, const enum hrtimer_mode mode);

ARGUMENTS

       expires
	   timeout value (ktime_t)

       delta
	   slack in expires timeout (ktime_t)

       mode
	   timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL

DESCRIPTION

       Make the current task sleep until the given expiry time has elapsed. The routine will return immediately unless the current task state has
       been set (see set_current_state).

       The delta argument gives the kernel the freedom to schedule the actual wakeup to a time that is both power and performance friendly. The
       kernel give the normal best effort behavior for "expires+delta", but may decide to fire the timer earlier, but no earlier than expires.

       You can set the task state as follows -

       TASK_UNINTERRUPTIBLE - at least timeout time is guaranteed to pass before the routine returns.

       TASK_INTERRUPTIBLE - the routine may return early if a signal is delivered to the current task.

       The current task state is guaranteed to be TASK_RUNNING when this routine returns.

       Returns 0 when the timer has expired otherwise -EINTR
