page fault

What this does is provides the capability to allocate memory for a process from the memory module which contains the processor that caused the page fault.

这样做的目的是，在内存模块中为处理器上产生缺页的进程提供内存分配的功能。

If the page fault is due to an instruction fetch ( meaning the process was trying to load an instruction from the page to execute), the kernel marks the file as computational.

如果是由于指令取出而导致的缺页（意味着该进程正在尝试加载来自该分页的指令，以便进行相关操作），那么内核会将该文件标记为计算性的。

For this paper, if it can do more comprehensive and systematic analysis for the fault diagnosis of the mechanical transmission system, it will be a new page about the fault diagnosis of railway vehicle.

对于本论文来说，如果它能够很好地对传动系统机械故障诊断做一个比较全面和系统的分析，那将是轨道车辆故障诊断方面崭新的一页。

Because the cost of a page fault is high, it is desirable that a garbage collector properly manage locality of reference.

因为页面错误的成本很高，所以垃圾收集器正确管理引用的区域性（locality）是很必要的。

The dsisr ( Data Storage Interrupt Status Register) indicates why the page fault could not be resolved.

dsisr（数据存储中断状态寄存器）表示页面错误无法解决的原因。

The dsirr ( Data Storage Interrupt reason Register) indicates the type of page fault that has occurred.

dsirr（数据存储中断原因寄存器）表示发生的页面错误的类型。

This event is called a page fault and is detected by hardware ( the MMU), and then managed by firmware after a page fault interrupt occurs.

这个事件被称为一个页面错误并被硬件（MMU）删除，出现页面错误中断后该事件由防火墙管理。

An instruction storage interrupt is a page fault on an instruction fetch.

指令存储中断通常是指在取出指令时发生页面错误。

If a process requests a page in memory and the system cannot find the page at the requested location, a page fault occurs.

如果某个进程请求内存中的某个页面，但是系统在所请求的位置中未找到该页面，则会发生页面错误。

For a particular virtual page, a page table entry will give a corresponding physical page or note that the page is not present ( indicating a page fault).

对于一个特定的虚拟页，根据一条页表记录可以找到对应的物理页，或者是页无法找到的提示（说明存在一个页错误）。

When an application references a page that is not mapped into real memory, the system generates a page fault.

如果应用程序引用了某个分页，而该分页并没有映射到实际内存中，那么系统将产生一个缺页。

Second, the detecting and startup procedure in Linux kernel 2.6.11.7 is analysed, and then new functions for page protecting and procedure of page fault exception handling are given.

其次，分析了最新的Linux2.6.11.7内核检测、启动NX的过程，归纳了新的页面保护函数，阐明了页面异常的处理过程。

When a page fault is taken on a file due to an instruction fetch, only the non-computational file transitions to the computational state.

如果某个文件因为指令取出发生了缺页，那么会将非计算性文件转换为计算性状态。

When a process page faults on a file ( meaning the process references a part of the file that is not currently cached in memory in a permanent storage page), the process generates a page fault.

当对某个文件出现进程缺页（意味着该进程引用了文件的部分内容，而这部分内容当前没有缓存在永久存储分页的内存中）的时候，该进程将产生一个缺页。

If it cannot find it there, a page fault occurs, and this signals the kernel to bring more pages into RAM from disk.

如果无法在RAM中找到这个页面，则出现一次缺页，然后向内核发出信号以便从磁盘中加载更多的页面到RAM。

The Study of the Page Fault in a Demand_paging System

关于请求分页系统下缺页问题的研究

The processor does this through the use of a page fault interrupt.

处理器通过缺页中断来进行这个操作。

Improving virtual memory page replacement can reduce page fault rate, and therefore improve the performance of the system.

改进页面置换算法，可以降低页面失败率，从而有效地提高系统性能。

The processor will store the virtual address which caused the page fault in a register, and then signal the operating system through an interrupt handler.

它把导致页面失效的虚拟地址装入寄存器中，再利用中断句柄来通知操作系统。

If it cannot be resolved by the VMM, or if the page fault occurs when interrupts are disabled, the system will crash.

如果不能够通过VMM解决，或者在禁用中断的情况下发生页面错误，那么将造成系统崩溃。

The page fault handling code is in mm/ memory.

页面出错处理代码位于mm下的memory。

Because of all kinds of uncertain factors ( including data I/ O, page fault, the dependency among transactions), the transactions have the dynamic unpredictability in the traditional transaction processing.

传统事务处理由于事务执行过程中的多种不确定因素（数据I/O、页面缺失、事务之间的各种相关性等），事务执行具有动态不可预报性。

A DSI occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory ( this is a page fault).

如果对当前不在物理内存中加载的虚拟地址进行引用（这是一个页面错误），则会出现DSI错误。

The dar ( Data Address Register) contains the address that the processor tried to access, which then caused a page fault.

dar（数据地址寄存器）包含处理器尝试访问的地址，这一行为将引发页面错误。

It is described how the virtual storage is implemented from the auxiliary storage management, main storage management and page management ( page fault handling, page replacement role etc.).

首先从辅存管理、主存管理及页面管理（缺页处理、淘汰规则等）三方面说明虚拟存储器是如何实现的。
