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.
如果某個文件因爲指令取出發生了缺頁，那麽會將非計算性文件轉換爲計算性狀態。
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.
系統內核所使用的內存空間通過特權碼（privileged code，2級或者更低）來標記，以防止用戶模式的程序訪問到內核空間而發生頁麪錯誤。
Writing process is complete page-based virtual memory address translation process management and simulation page fault handling.
編寫程序完成頁式虛擬存儲琯理中地址轉換過程和模擬缺頁中斷的処理。
