This is done by calling + * erts_thr_q_clean(). In the SMP case thread progress may have to be made + * before cleaning can continue. If so, erts_thr_q_need_thr_progress() in + * combination with erts_thr_progress_wakeup() can be used in order to + * request a wakeup at appropriate time. + * + * Enqueuing implies memory allocation and dequeuing implies memory + * deallocation. Memory allocation can be moved to another more suitable + * thread using erts_thr_q_prepare_enqueue() together with + * erts_thr_q_enqueue_prepared() instead of using erts_thr_q_enqueue(). + * Memory deallocation can can be moved to another more suitable thread by + * disabling auto_finalize_dequeue when initializing the queue and then use + * erts_thr_q_get_finalize_dequeue_data() together + * erts_thr_q_finalize_dequeue() after dequeuing or cleaning. + * + * Ending the life of the queue using either erts_thr_q_destroy() + * or erts_thr_q_finalize() impies cleaning the queue. Both functions + * return the cleaning result and may have to be called multiple times + * until the queue is clean. Once one of these functions have been called + * enqueuing is not allowed. This has to be synchronized by the user. + * If auto_finalize_dequeue has been disabled, the finalize dequeue + * functionality has to be called after ending the life of the queue just + * as when dequeuing or cleaning on a queue that is alive. + * + * ------------------------------------------------------------------------- + */ + +#ifdef HAVE_CONFIG_H +# include "config.h" +#endif + +#include "erl_thr_queue.h" + +#if defined(DEBUG) +#define ERTS_THR_Q_DBG_CHK_DATA 1 +#else +#define ERTS_THR_Q_DBG_CHK_DATA 0 +#endif + +#define ERTS_THR_Q_MAX_CLEAN_REACHED_HEAD_COUNT 100 +#define ERTS_THR_Q_MAX_SCHED_CLEAN_OPS 50 +#define ERTS_THR_Q_MAX_DEQUEUE_CLEAN_OPS 3 + +#define ERTS_THR_Q_MAX_FINI_DEQ_OPS 50 + +#ifdef ERTS_SMP +ERTS_SCHED_PREF_QUICK_ALLOC_IMPL(sl_element, + ErtsThrQElement_t, + 1000, + ERTS_ALC_T_THR_Q_EL_SL) +#else + +static void +init_sl_element_alloc(void) +{ +} + +static ErtsThrQElement_t * +sl_element_alloc(void) +{ + return erts_alloc(ERTS_ALC_T_THR_Q_EL_SL, + sizeof(ErtsThrQElement_t));
