镜像文件的制作及恢复方法、处理器和嵌入式系统
摘要：
本申请涉及计算机技术领域，特别涉及一种镜像文件的制作及恢复方法、处理器和嵌入式系统，用以解决镜像文件制作速度慢的技术问题。制作方法包括：基于第一虚拟内核进行镜像加载，得到第二虚拟内核；确定接收到镜像文件制作指令后，通过第一虚拟内核复制并保存非进程状态数据；启动第二虚拟内核，并停止运行第一虚拟内核；通过第二虚拟内核读取第一虚拟内核的进程状态数据；通过第二虚拟内核对进程状态数据和非进程状态数据进行压缩，获得第一镜像文件。恢复方法包括，第二虚拟内核获取第一镜像文件，对其进行解压，切换到第一虚拟内核运行，恢复系统运行。本申请节省了复制和保存进程状态数据所消耗的时间和保存进程状态数据占用的内存空间。
摘要（英）：

The invention relates to the technical field of computers, in particular to a mirror image file manufacturing and recovering method, a processor and an embedded system, and aims to solve the technicalproblem of low mirror image file manufacturing speed. The manufacturing method comprises the steps of performing mirror image loading based on a first virtual kernel to obtain a second virtual kernel; after it is determined that the mirror image file manufacturing instruction is received, copying and storing non-process state data through a first virtual kernel; starting the second virtual kernel, and stopping running the first virtual kernel; reading process state data of the first virtual kernel through the second virtual kernel; and compressing the process state data and the non-process state data through the second virtual kernel to obtain a first mirror image file. The recovery method comprises the steps that the second virtual kernel obtains a first mirror image file, decompresses the first mirror image file, switches to the first virtual kernel for operation and recovers system operation. The time consumed for copying and storing the process state data and the memory space occupied for storing the process state data are saved.
