http://subweb.lib.nccu.edu.tw/exam/data/master/cs/cs100.pdf 第五題 有關狀態轉換的部分 a. will the thread change state if it incurs a page fault? if so, to what new state? b. will the thread change state if it generates a TLB miss that is resolve in the page table? if so, to what new state? c. will the thread change state if an address reference is resolved in the page table? if so, to what new state? 能請強者稍微解釋一下這幾個概念嗎 page fault跟這個transition diagram 到底是什麼樣的關係呢 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.161.185.20
