中断handler中通过调用到work_struct work结合queue_struct来调用报点函数 static void tpd_eint_handler(void) { queue_work(mtk_tpd_wq, &work); } 1. 2. 3. 4. 在模块exit函数中,注销workqueue_struct destroy_workqueue(mtk_tpd_wq); 1. ===定时处理delayed_work=== delayed_work是在work_struct的基...
INIT_WORK(work, func); 其中参数1是个work_struct结构体,参数2是个函数名,通过INIT_WORK将work_struct与一个函数建立起来. 其中work_struct结构体定义如下所示: structwork_struct { atomic_long_t data;structlist_head entry; work_func_t func;//函数指针,指向func函数#ifdef CONFIG_LOCKDEPstructlockdep_ma...

work_struct:工作队列调度的最小单位,work item; workqueue_struct:工作队列,work item都挂入到工作队列中; worker:work item的处理者,每个worker对应一个内核线程; worker_pool:worker池(内核线程池),是一个共享资源池,提供不同的worker来对work item进行处理; pool_workqueue:充当桥梁纽带的作用,用于连接workqueue...

1、定义struct work_struct irq_queue; 2、初始化INIT_WORK(&irq_queue,do_irq_queuework); 3、调用方法:schedule_work(&rq_queue); 注,调用完毕后系统会释放此函数,所以如果想再次执行的话,就再次调用schedule_work()即可。 另外,内核必须挂载文件系统才可以使用工作队列。我的理解是:工作队列也属于调度,如果...
RHEL6.8: rpciod kernel crash in worker_thread due to corrupt work_struct, __list_add corruption during mount GETPORT rpcbind call Solution In Progress - Updated June 14 2024 at 6:00 PM - English Issue First there is a WARN_ON backtrace indicating that a list_head is corrupted Raw <4...
integrated into workqueue in your patchset, from which what you need might be: struct ioprio_work { /*** the work item to be scheduled ***/ struct work_struct work; /*** the stuff need for ioprio ***/ /* If the work does submit_bio, io priority may be needed. */ unsigned sho...
Since nfsd4_state_shrinker_count always calls mod_delayed_work with 0 delay, we can replace delayed_work with work_struct to save some space and overhead. Also add the call to cancel_work after unregister the shrinker in nfs4_state_shutdown_net. Signed-off-by: Dai Ngo <dai.ngo@oracle...
