page table entry 中文意思是什麼
page table entry
解釋
頁表項目-
If the page being looked for has been swapped out, a swap entry is stored at in the pte table which is used when there is a page fault for finding the page frame to reload in memory
如果正在查找的頁已轉出,那麼就會在pte表中存儲一個交換條目, (在缺頁的情況下)以定位將哪個頁框重新加載到內存中。 -
Each entry will be a pointer to a lower table of a smaller - sized directory, so the pgd is a directory of page tables
每項都指向一個更小目錄的低級表,因此pgd就是一個頁表目錄。 -
If each page - table entry consumes 8 bytes, then that would be 2 mb of overhead for every 1 gb of memory mapped
如果每個頁表條目消耗8個位元組,那些每映射1 gb內存需要2 mb的開銷。 -
Register. the directory field within the linear address determines the entry in page directory that points to the proper page table
寄存器中。線性地址中的directory欄位確定頁目錄中指向恰當的頁表條目。 -
Each entry in the pte chain uses 4 bytes to store a pointer to the page - table entry and an additional 4 bytes to store the pointer to the next entry on the chain
Pte鏈的每一個條目使用4個位元組來存儲指向頁表條目的指針,用另外4個位元組來存儲指向鏈的下一個條目的指針。 -
However, before they can be swapped out, every single process mapping that page must be found so that the page - table entry for the page in that process can be updated
不過,在它們可以被交換出去之前,必須找到映射那個頁的每一個進程,這樣那些進程中相應頁的頁表條目才可以被更新。
