Hi, I am trying to implement single 10sec precision periodic timer using TW. Below is the config. using the reference from test_tw_timer.c (Really helpful).
tw_timer_wheel_init_2t_1w_2048sl with 0.1 sec granularity. tw_timer_start_2t_1w_2048sl with 100 as ticks. I have used the process node approach with tw_timer_expire_timers_2t_1w_2048sl check at every 0.1 sec using vlib_process_suspend(...). In the callback, timer is again started. My expectation was I would be receiving callback to expired_timer_single_callback() at every 10 sec. In actual, the callbacks are getting called at every 10sec apart. But sometimes there are some unwanted callback at irregular frequency for the same handle( i.e timer_id, pool_index). Note that this is the case either for main_core or workers. For erroneous scenarios, time diff from previous callback is inorder of ~ 0.1 ms(expected 10sec). Any pointers would of great help. Thanks, -Shaligram
