page fault

基本解释

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。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
系统内核所使用的内存空间通过特权码（privileged code，2级或者更低）来标记，以防止用户模式的程序访问到内核空间而发生页面错误。
Writing process is complete page-based virtual memory address translation process management and simulation page fault handling.
编写程序完成页式虚拟存储管理中地址转换过程和模拟缺页中断的处理。
