Background
The system is dormant, that is, the operating system of the computing device automatically stores all data in the memory to the swap space, and cuts off power supply to all devices, which is equivalent to a power saving state of the computing device. For example, a period of time may be set for operating the computing device, and the computing device may enter a sleep state. Under the state, documents and programs opened in the memory can be switched into the swap space, and the swap space comprises two forms, namely a swap partition and a swap file. However, if the swap space is insufficient, the system may fail to sleep, and if the configured swap space is much larger than the memory size, a large amount of waste of the disk space may be caused. Therefore, it is necessary to specify a proper size for the swap space.
At present, the size of the swap space can be designated only when an operating system is installed, and once the operating system is installed, the process of adjusting the size of the swap space is very complicated. The swap space is a part of storage space divided on the disk. The swap space comprises a swap partition and a swap file.

FIG. 2 shows a flow diagram of an operating system hibernation method 200 according to one embodiment of the invention. The method 200 is suitable for execution in the computing device 100, and the method 200 includes steps S210 to S290. By the method 200, the swap space can be automatically expanded according to the size of data in the memory when the operating system is in a sleep state, so that the normal sleep function of the operating system is ensured.
Step S210 is executed first to detect whether a condition of operating system hibernation is reached. The sleep condition is preset by the user, or may be default by the system, which is not limited. Setting the sleep time is prior art, and is not described herein, and all methods for setting the sleep time are within the scope of the present invention.
When the computing device detects that the operating system hibernation condition is reached, step S220 is continuously executed to obtain the size of the swap space and the size of the current memory that exist in the computing device, where the size of the current memory is the size of data in the current memory. And then, executing step S230, determining whether to expand the swap space according to the size of the current memory and the size of the existing swap space, specifically, determining whether the size of the current memory is larger than the size of the existing swap space, if so, indicating that the existing swap space cannot accommodate all data in the current memory, the swap space needs to be expanded, and if not, indicating that the existing swap space can accommodate all data in the current memory, the swap space does not need to be expanded.
If the swap space does not need to be expanded, step S240 is executed to swap the memory data of the computing device into the existing swap space.
If the swap space needs to be expanded, step S250 is executed to determine the size of the target swap space. The size of the target space can be determined in a user-defined mode of the swap space size, and the size of the target space can also be determined according to the current memory size and the physical memory size of the computing device.
In some embodiments, the step of determining the size of the target space by means of user-defined swap space size includes: the method includes that a user specifies the size of a swap space on a user interaction interface, after a certain interface is triggered, a computing device responds to the operation of specifying the size of the swap space on the user interaction interface, the size of the swap space specified by the user is obtained, and the size of the swap space specified by the user is used as the size of a target swap space.
In some embodiments, determining the size of the target space based on the current memory size and the physical memory size of the computing device comprises: and judging whether the size of the current memory is larger than that of the physical memory, if so, taking the size of the target swap space as the product of the target coefficient and the size of the current memory, and taking the target coefficient as a numerical value not smaller than 1. The size of the target coefficient may be set according to hardware of the computing device, which is not limited by the present invention, for example, the target coefficient may be any value between 1 and 2. When the size of the current memory is not larger than that of the physical memory, the size of the target swap space is any value in the range of the size of the current memory and the physical memory.
After the size of the target swap space is determined, step S260 is continuously executed to delete the existing swap space, step S270 is continuously executed to create a swap file with the size equal to that of the target swap space as the target swap file. Specifically, whether the size of the residual storage space of the external storage device in the computing device is smaller than that of the target swap space is judged, if not, the residual storage space is enough, and then a swap file with the size equal to that of the target swap space is created to serve as the target swap file. If the size of the remaining storage space of the external storage device in the computing device is smaller than the size of the target swap space, which indicates that the remaining storage space is insufficient, the swap file with the size equal to that of the target swap space cannot be created, that is, the creation of the swap file fails, and step S210 is continuously executed.
After the target swap file is successfully created, step S280 is executed to set the target swap file as a target swap space, which is equivalent to expanding the swap space.
In some embodiments, the process of expanding swap space is as follows: firstly, obtaining the path of the existing swap space, updating the path of the target swap space into the path of a target swap file, formatting the target swap file into a swap file type, and finally activating the formatted target swap file to realize the capacity expansion of the swap space.
After the swap space is expanded, step S290 is continuously executed to swap the memory data of the computing device into the target swap space, so as to implement the hibernation of the operating system.
Therefore, automatic expansion of the swap space in the sleep process of the operating system is achieved. Steps S210 to S290 are performed whenever the os hibernation is detected.
FIG. 3 is a block diagram illustrating an operating system hibernation apparatus 300 according to an embodiment of the present invention. The apparatus 300 includes an obtaining module 310, a determining module 320, a capacity expansion swap space module 330, and a hibernation module 340, which are coupled in sequence.
The obtaining module 310 is adapted to, when it is detected that the operating system hibernation condition is reached, obtain the size of the swap space and the size of the current memory that are already present in the computing device.
The judging module 320 is adapted to judge whether the swap space needs to be expanded according to the size of the current memory and the size of the existing swap space, and determine the size of the target swap space if the swap space needs to be expanded.
And the capacity expansion swap space module 330 is suitable for deleting the existing swap space, creating a swap file with the size equal to that of the target swap space as the target swap file, and setting the target swap file as the target swap space.
And the dormancy module 340 is adapted to swap in the memory data to the target swap space to implement the dormancy of the operating system.
It should be noted that the operating principle of the os hibernation apparatus 300 is similar to that of the os hibernation method 200, and reference may be made to the description of the os hibernation method 200 for relevant points, which is not described herein again.
According to the sleep method of the operating system, when the condition that the operating system is in sleep is detected, the size of the existing swap space and the size of the current memory in the computing device are obtained, whether the swap space needs to be expanded is judged according to the size of the current memory and the size of the existing swap space, when the swap space needs to be expanded, the existing swap space is deleted, the swap space with enough size is created, and memory data of the computing device is exchanged into the newly created swap space, so that the sleep of the operating system is realized. Therefore, in the invention, when the operating system is in a sleep state, the swap space is automatically expanded according to the size of data in the memory, so that the normal sleep function of the operating system is ensured.
