工作队列结构体

用途：工作队列和工作项控制块结构

来源：kernel/include/os_dummy.h:320

一、工作项结构体

struct dummy_work
{
    os_list_node_t work_node_dummy;

    void (*work_func_dummy)(void *data); /* Callback function for work. */
    void     *data_dummy;            /* Private data for callback function. */
    dummy_timer_t work_timer_dummy;

    struct dummy_workqueue *volatile workqueue_dummy; /* Workqueue used to execute work. */

    uint8_t flag_dummy;
    uint8_t object_inited_dummy; /* If os_work is inited, value is OS_KOBJ_INITED */
};
typedef struct dummy_work dummy_work_t;

二、工作队列结构体

struct dummy_workqueue
{
    os_list_node_t work_list_head_dummy;
    dummy_work_t  *work_current_dummy; /* Work in progress on workqueue */
    dummy_task_t   queue_task_dummy;

    os_spinlock_t     lock_dummy;   /* Spin lock. */
    dummy_semaphore_t sem_id_dummy; /* Semaphore for synchronization. */

    uint8_t object_inited_dummy; /* If os_workqueue is inited, value is OS_KOBJ_INITED */
};
typedef struct dummy_workqueue dummy_workqueue_t;
