这个函数不能从中断上下文调用。
该字段只能在中断上下文中被填充。
问题在于，有多少任务需要在中断上下文完成？
The question is, how much work should be done in the interrupt context?
中断处理程序始终在中断上下文中运行。
绝对安全使用内核链表在中断上下文，但但检索任何中断处理程序是一个坏主意。
It is perfectly safe to use kernel linked lists in interrupt context, but but retrieving anything in interrupt handlers is a bad idea.
有一点值得指出的是，这些tasklet/bottomhalf会关闭这个中断上下文（软件中断）。
It is important to note that these tasklets/bottom halves will run close to the interrupt context (software interrupt).
快速切换是内核的一个特性，它充许设备驱动在对进入流量的中断上下文中，使用一个小的缓存(经过所有的软件层)。
FAST switching (also called FASTROUTE) was a kernel feature that allowed device drivers to route incoming traffic during interrupt context using a small cache (bypassing all the software layers).
在这些寄存器的 #define宏前面，还应该定义另外一个宏，它用来说明 ISR 是在模拟模式中运行还是在原来的中断上下文中运行的。
On top of these register #define macros, you should also define another macro that dictates whether the ISR will run in simulation mode or in the original interrupt context. For example
被中断的上下文需要多长时间才能恢复？
中断导致上下文丢失，因此第二个问题是没有意义的。
The interruption causes a loss of context so that the second question is meaningless.
他编写这个新调度器的动机是为唤醒、上下文切换和定时器中断开销建立一个完全o(1)的调度器。
His motivation in working on the new scheduler was to create a completely o (1) scheduler for wakeup, context-switch, and timer interrupt overhead.
由于上下文的恢复是一个过程，因此在中断之后其需要一些时间来重返回到最高速度上。
Since context recovery is a process, it takes some time to get back to maximum speed after an interrupt
bottom - half处理过程在内核上下文完成，这意味着允许中断操作。
The bottom-half processing is performed in the kernel context, which means that interrupts are enabled.
mpstat命令报告每个CPU的使用情况，也报告延伸的统计信息，包括上下文切换、中断等等。
The mpstat command reports CPU utilization on a per-CPU basis, and it reports extended statistics, including context switches, interrupts, and so on.
探测（probe）：中断正常系统动作，获取关于当前上下文的信息。
probe: Interrupting normal system action to obtain information about current context.
VxWorks可以跟踪所有你感兴趣的系统事件，包括上下文切换、同步对象的使用和中断。
VxWorks can be run in a mode where it records a total trace of all interesting system events, including context switches, uses of synchronization objects, and interrupts.
CPU上的每个处理器都拥有自己的CSA(当前保存区)指针，指向当线程或中断处理程序由于上下文切换而被中断或交换时使用的MST。
Each processor on the CPU has its own CSA (current save area) pointer that points to the MST that is to be used when a thread or interrupt handler is interrupted or swapped due to context switch.
软中断用于在内核线程上下文中处理时间要求严格的处理过程（软件中断）。
Softirqs were used for time-critical processing (software interrupts) in the kernel thread context.
你能从上下文中断定生词的意思吗？
Can you figure out the meaning of unknown words from the context?
上下文缓存是减少上下文信息访问开销、降低信息传输数量、缓解连接中断引起的程序不可用性的有效途径。
Using context cache is an effective way to reduce the overhead of context access, decrease the amount of information transmission and improve the application availability when disconnections occur.
