virtual io 中文意思是什麼
virtual io
解釋
虛擬輸入輸出-
In addition to bypassing the complexity of building a kernel to emulate and a file system image to boot into, and configuring a virtual network device for io, this shortcut also speeds up emulation, as the reams of kernel instructions that would have run to handle the system call - from the exception handler through the vfs and the device driver - are bypassed
除了繞開構建一個用於模擬的內核和一個用於啟動到其中的文件系統鏡像,以及為io配置虛擬網路設備的復雜性之外,這條捷徑還加快了模擬的速度,因為繞開了從異常處理程序到vfs再到設備驅動程序的很多內核指令,而這些內核指令本來就是用來處理系統調用的。
