STRUCT HRTIMER(9) Driver Basics STRUCT HRTIMER(9)
NAME
struct_hrtimer - the basic hrtimer structure
SYNOPSIS
struct hrtimer {
struct rb_node node;
ktime_t _expires;
ktime_t _softexpires;
enum hrtimer_restart (* function) (struct hrtimer *);
struct hrtimer_clock_base * base;
unsigned long state;
#ifdef CONFIG_TIMER_STATS
int start_pid;
void * start_site;
char start_comm[16];
#endif
};
MEMBERS
node
red black tree node for time ordered insertion
_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)
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
