struct hrtimer_clock(9)

NAME

struct_hrtimer_clock_base - the timer base for a specific clock

SYNOPSIS

  clockid_t index;
  struct rb_root active;
  struct rb_node * first;
  ktime_t resolution;
  ktime_t (* get_time) (void);
  ktime_t (* get_softirq_time) (void);
  ktime_t softirq_time;
#ifdef CONFIG_HIGH_RES_TIMERS
  ktime_t offset;
  int (* reprogram) (struct hrtimer *t,struct hrtimer_clock_base *b,ktime_t n);
#endif
};

MEMBERS

cpu_base

first

pointer to the timer node which expires first

resolution

the resolution of the clock, in nanoseconds

get_time

function to retrieve the current time of the clock

get_softirq_time

function to retrieve the current time from the softirq

softirq_time
