Hi,
I have tw implementation and its working fine for sometime and later the
timer_expired_callback function is not invoked even though the tw node is
getting scheduled.
Detals:
tw_node of type VLIB_NODE_TYPE_INPUT.
Node function calls run_timer_wheels :
run_timer_wheels(vm)
{
tw_timer_wheel_1t_1w_2048sl_t* tw;
f64 now;
u32 thread_id = vlib_get_current_worker_index();
tw = &p_main->timer_wheels[thread_id];
now = vlib_time_now (vm);
tw_timer_expire_timers_1t_1w_2048sl(tw, now);
}
Init:
initialize_timer_wheels ()
{
.....
.....
tw_timer_wheel_1t_1w_2048sl_t* tw;
int i=0;
u32 n_workers = vlib_num_workers();
vec_validate (p_main->timer_wheels, n_workers-1);
for(i=0; i<n_workers; i++)
{
tw = &p_main->timer_wheels[i];
tw_timer_wheel_init_1t_1w_2048sl (tw, timer_expired_callback, 0.1, 1024);
tw->last_run_time = vlib_time_now (vlib_get_main());
}
}
Start Function:
start_timer_wheels()
{
....
u32 n_workers = vlib_num_workers();
for(int i=0; i<n_workers; i++)
{
p_main->stop_timer_handle[i] =
tw_timer_start_1t_1w_2048sl(&p_main->timer_wheels[i],
i /*elt-index*/,
0 /*timer-id*/,
1 /*interval*/);
}
return 0;
}
timer_expired_callback (u32 * expired_timers)
{
........
int i = 0;
u32 thread_id =
vlib_get_current_worker_index();
vlib_main_t *vm = vlib_get_main();
f64 time_now = vlib_time_now(vm);
for (i = 0; i < vec_len (expired_timers); i++)
{
/* application logic */
}
p_main->stop_timer_handle[thread_id] =
tw_timer_start_1t_1w_2048sl(&p_main->timer_wheels[thread_id],
thread_id,
0,
1);
}
Any thing I am missing here.
thanks.
