Abstract

The invention discloses a system hibernation method and apparatus. The method comprises the steps of calculating a memory number required to be applied; according to the calculated memory number, dividing a nonvolatile memory to obtain a corresponding preset number of physical memories; converting the physical memories obtained by dividing the nonvolatile memory into block devices; and storing internal mirror images by using the newly generated block devices instead of a disk to realize system hibernation of the nonvolatile memory. According to the system hibernation method and apparatus provided by the invention, during system hibernation, a system stores data required to be stored into the block devices formed by converting the memories according to an original process instead of the original disk, and the speed of reading the data from the memory is higher than the speed of reading the data from the disk, so that the system wakeup time is shortened and the user experience and the working efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of operating systems, in particular to a method and device for system dormancy. Background technique [0002] Currently, in the operating system, two mechanisms of system sleep and hibernation are provided, which not only saves system resources, but also improves user experience and work efficiency. When the user uses the sleep or hibernation mechanism of the system, all the current work of the user will be recorded and saved, and the system will resume to the previous working state when it wakes up. [0003] The current sleep mechanism in the system allows the system to enter a partial power-off state, save the data in the memory, and when it wakes up, the data is read from the memory and the system returns to the previous state, and the time required for wake-up is relatively short; while the system The hibernation mechanism of the system is to put the system into a state of complete power failure...
