查询词典 handler

If an interrupt comes in from an I/O device, the kernel effectively stops the current task, runs the interrupt handler, and then returns to the current task.

当 I/O 设备上有中断输入时，内核马上停止处理当前的任务，转向处理当前的输入，然后返回运行当前的任务。

When executing an interrupt handler or bottom half, the kernel is in interrupt context.

最近看lkd，总是能看到进程上下文和中断上下文，以前的理解是进程上下文是在用户空间而中断上下文是在内核空间，现在看来真是差的很多，完全误解了这两个术语的意思，上网google了一下，算了对其有了正确的认识，现转载过来，希望能帮助更多的人认识这两个东西。

If you do not access your lock in a hardware interrupt handler, but you do via software interrupts (in code that runs out of a tasklet, for example, a topic covered in Chapter 7), you can use spin_lock_bh to safely avoid deadlocks while still allowing hardware interrupts to be serviced.

如果你没有在硬件中断的控制代码中访问锁，而是借助了软件中断(例如在运行于一个任务列表之外的代码中，第7章中将谈到)，当硬件中断仍被允许时你可以使用 spin_lock_bh 来安全地避免死锁情况。

On the basis of reseaching the magnetic card technology,we divide the procedure into the following modules:the initialization module,the interrupt handler routine,the decrypting module,the analysis module,and then implement each specific module in detail.

在研究磁卡技术的基础上，根据磁卡读卡器驱动程序的核心任务，将驱动程序划分为初始化模块、中断处理模块、解码模块和解析模块，并详细地阐述了各个模块的具体实现过程。

An interrupt handler will then re-enable the device queue with netif_start_queue so that the kernel can restart transmissions.

然后一个中断句柄用netif_start_queue来重新使能设备队列，这样内核就可以重新启动数据传输。

Also, beware, some sources of interrupts are not cleared by servicing the interrupt handler, so you need to clear them BEFORE enabling interrupts or you will endlessly re-enter your code and blow your stack.

此外要小心，有些中断源没有被中断服务程序清除，所以你要在允许中断前清除它们，否则你将无止境地重入你的中断代码并耗尽你的堆栈。

By transplanting packet scheduling from the egress point of network interfaces to the soft interrupt handler that processes incoming packets, the new method can eliminate disadvantages of the old traffic control scheme without introducing any additional demerits.

这种新的机制将网络带宽的管理和调度从网络接口的出口点转移到处理接收到的网络包的系统软件中断处理程序中，从而克服了原来的流量管理机制的缺点。

At the same time,on the basis of analyzing the contactless IC card's working process and RC531's operating principles,we partition the contactless device driver into the initialization module,the command executing module,the interrupt handler routine, the seeking card module, the card's power-on and power-off module,as well as read/write operating module,and then implement each module in detail.

同时，通过分析非接触式IC卡的工作过程和RC531的工作原理，将非接触式IC卡读写器的驱动程序划分为初始化模块、命令执行模块、中断处理模块、寻卡模块和卡片上电、下电模块，以及读/写操作模块，并详细描述各模块的实现过程。

By reducing the levels of the device driver, using the DMA pipeline and reusing the Interrupt handler, the cost of software declines a lot, and the performance of RAM is utilized sufficiently.

设计中通过精简驱动层次、多级流水、中断合并等技术，将IO访问路径上的软件开销降低，从而充分发挥RAM在高并发随机访问下的性能。

This function registers a handler, first making sure that the requested interrupt is a valid one, and that it is not already allocated to another device unless both devices understand shared IRQs (see the later section "Interrupt sharing").

这个函数注册一个句柄，首先确保请求的中断是一个有效的中断号，而且它还没有分配给另一个设备，除非两个设备都明确的使用共享IRQ(参见后面的一节"Interrupt sharing")。

A backer of an Afghan law that critics say legalizes marital rape has rejected the international outcry as foreign meddling.

饱受批评的一项法律的拥护者说合法化的婚内暴力不会受国际舆论的干涉。

Years ago, a ancient Egyptian fleet went to the Land of punt for seeking a kind of flavor named "myrrh", and aromatic plants which has dense exotic style for the queen Hatshepsut.

3500年前的一个古埃及的舰队到&彭特之地&寻找一种叫没药的香料。
