This field will only be filled in in interrupt context.
该字段只能在中断上下文中被填充。
It is important to note that these tasklets/bottom halves will run close to the interrupt context (software interrupt).
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 perfectly safe to use kernel linked lists in interrupt context, but but retrieving anything in interrupt handlers is a bad idea.
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。
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
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。
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).
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)。
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.
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。
Almost all interrupt handlers are converted to kernel threads that run in process context.
几乎所有的中断处理程序都被转换为运行在进程中的内核线程。
The hardness of this approach depends mostly on the CPU interrupt structure and context-switch hardware support.
这种方法的硬度主要取决于CPU中断结构和环境转换的硬件支持。
His motivation in working on the new scheduler was to create a completely o (1) scheduler for wakeup, context-switch, and timer interrupt overhead.
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。
Since context recovery is a process, it takes some time to get back to maximum speed after an interrupt
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 it knows exactly which registers will be used for any interrupt, it can determine the context size dynamically, based on the state of the program at the time of compilation.
因为他准确知道中断会用到哪个寄存器，所以它能够以程序编缉时的状态为基础，动态决定代码大小。
The hardware context switch mechanism was adopted by MPC8250. It makes interrupt responding time of MPC8250 has less relativity with operation system.
MPC8250采取了基于硬件的中断现场保护机制，系统中断响应时间与所采用操作系统相关性较小。
This paper studies the interrupt latency and context-switch time of embedded real-time operating system, and about the interrupt latency a non-maskable interrupt idea is put forward.
本文分析了嵌入式实时操作系统的两个重要的性能指标任务切换时间和中断延时及对实时控制的影响，并针对中断延时提出非屏蔽中断的改进方法。
