STRUCT HRTIMER(9)                         Driver Basics                         STRUCT HRTIMER(9)



NAME
       struct_hrtimer - the basic hrtimer structure

SYNOPSIS
       struct hrtimer {
         struct timerqueue_node node;
         ktime_t _softexpires;
         enum hrtimer_restart        (* function) (struct hrtimer *);
         struct hrtimer_clock_base * base;
         u8 state;
         u8 is_rel;
       #ifdef CONFIG_TIMER_STATS
         int start_pid;
         void * start_site;
         char start_comm[16];
       #endif
       };

MEMBERS
       node
           timerqueue node, which also manages node.expires, the absolute expiry time in the
           hrtimers internal representation. The time is related to the clock on which the timer
           is based. Is setup by adding slack to the _softexpires value. For non range timers
           identical to _softexpires.

       _softexpires
           the absolute earliest expiry time of the hrtimer. The time which was given as expiry
           time when the timer was armed.

       function
           timer expiry callback function

       base
           pointer to the timer base (per cpu and per clock)

       state
           state information (See bit values above)

       is_rel
           Set if the timer was armed relative

       start_pid
           timer statistics field to store the pid of the task which started the timer

       start_site
           timer statistics field to store the site where the timer was started

       start_comm[16]
           timer statistics field to store the name of the process which started the timer

DESCRIPTION
       The hrtimer structure must be initialized by hrtimer_init
