Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to an operating system hibernation method, device, computing equipment and readable storage medium. Background Art

[0002] System hibernation means that the operating system of the computing device automatically transfers all the data in the memory to the swap space and cuts off the power supply to all devices, which is equivalent to the power saving state of the computing device. For example, you can set a period of time for the computing device to enter the hibernation state. In this state, the documents and programs opened in the memory will be swapped into the swap space. The swap space includes two forms, namely swap partition and swap file. However, if the swap space is insufficient, the system hibernation will fail. If the configured swap space is much larger than the memory size, it will cause a lot of waste of disk space. Therefore, it is very necessary to specify a suitable size for the swap space.

[0003] Currently, the size of the swap space is only specified when the operating system is installed. Once the operating system is installed, it is very cumbersome to adjust the size of the swap space. The swap space is a part of the storage space divided on the disk. The swap space includes the swap partition and the swap file.

[0004] Therefore, it is desired to provide an operating system hibernation method to solve the technical problem that the existing system hibernation method cannot automatically adjust the size of the swap space during hibernation. Summary of the invention

[0005] To this end, an embodiment of the present invention provides an operating system hibernation method and device, in an effort to solve or at least alleviate the above problems.

[0006] According to one aspect of an embodiment of the present invention, a method for hibernating an operating system is provided, which is executed in a computing device, and the method includes: when it is detected that a condition for hibernating the operating system is met, obtaining the size of the swap space already existing in the computing device and the size of the current memory; judging whether it is necessary to expand the swap space according to the size of the current memory and the size of the existing swap space; if it is necessary to expand the swap space, determining the size of the target swap space; deleting the existing swap space; creating a swap file of the same size as the target swap space and setting it as the target swap space; swapping the memory data of the computing device into the target swap space to achieve hibernation of the operating system.

[0007] Optionally, the step of determining the size of the target swap space includes: in response to an operation of specifying the size of the swap space in the user interaction interface, obtaining the size of the specified swap space; and using the size of the specified swap space as the size of the target swap space.

[0008] Optionally, the step of determining the size of the target swap space includes: determining whether the current memory size is greater than a target value; if the current memory size is greater than the target value, the size of the target swap space is the product of a target coefficient and the current memory size, wherein the target value is the size of the physical memory of the computing device, and the target coefficient is a value not less than 1; if the current memory size is not greater than the target value, the size of the target swap space is any value within the range of the current memory size and the target value.

[0009] Optionally, the step of setting the target swap file as the target swap space includes: updating the path of the target swap space to the path of the target swap file; formatting the target swap file as a swap file type; and activating the formatted target swap file.

[0010] Optionally, the step of creating a swap file of equal size to the target swap space includes: determining whether 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; if not, creating a swap file of equal size to the target swap space as the target swap file.

[0011] Optionally, the step of determining whether the swap space needs to be expanded according to the current memory size and the existing swap space size includes: determining whether the current memory size is larger than the existing swap space size; if so, the swap space needs to be expanded; if not, the swap space does not need to be expanded.

[0012] The operating system hibernation method provided by the present invention also includes the step of: if there is no need to expand the swap space, swapping the memory data of the computing device into the existing swap space.

[0013] According to another aspect of an embodiment of the present invention, there is provided an operating system hibernation device, which is executed in a computing device, and the device includes: an acquisition module, adapted to acquire the size of the swap space already existing in the computing device and the size of the current memory when it is detected that the conditions for the operating system to hibernate are met; a determination module, adapted to determine whether the swap space needs to be expanded based on the size of the current memory and the size of the existing swap space, and if the swap space needs to be expanded, determine the size of the target swap space; a swap space expansion module, adapted to delete the existing swap space, and create a swap file of the same size as the target swap space, and set it as the target swap space; a hibernation module, adapted to swap memory data into the target swap space to achieve operating system hibernation.

[0014] According to another aspect of the present invention, a computing device is provided, comprising: at least one processor; and a memory storing program instructions, wherein the program instructions are configured to be suitable for execution by the at least one processor, and the program instructions include instructions for executing the method as described above.

[0015] According to another aspect of the present invention, a readable storage medium storing program instructions is provided. When the program instructions are read and executed by a computing device, the computing device executes the method described above.

[0016] According to the operating system hibernation method of an embodiment of the present invention, when it is detected that the operating system hibernation condition is met, the size of the swap space already existing in the computing device and the size of the current memory are obtained, and whether the swap space needs to be expanded is determined based on the size of the current memory and the size of the existing swap space. When expansion is required, the existing swap space is deleted, a swap space of sufficient size is created, and the memory data of the computing device is swapped into the newly created swap space to achieve operating system hibernation. It can be seen from the above content that the present invention automatically expands the swap space according to the size of the data in the memory when the operating system is hibernating to ensure the normal hibernation function of the operating system.

[0024] It is worth noting that no matter whether the operating system hibernation method provided by the present invention is implemented as an application or a plug-in, when the operating system is started, that is, the computing device 100 is turned on and the user logs in successfully and enters the user interface, the operating system hibernation method provided by the present invention will be started at the same time.

[0025] In some embodiments, the executable program of the operating system hibernation method provided by the present invention is stored in the / usr / bin / directory. In order to realize the self-starting of the operating system hibernation method when the operating system is started (the present invention does not limit the startup method, for example, the self-starting of the operating system hibernation method is realized with root authority), a configuration file of a predetermined type corresponding to the executable program of the operating system hibernation is created, and the configuration file of the predetermined type is stored in the / usr / lib / systemd / system directory.

Computer storage media may include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information (e.g., computer-readable instructions, data structures, or program modules).

[0043] According to one aspect, communication media is implemented by computer readable instructions, data structures, program modules, or other data in a modulated data signal (e.g., a carrier wave or other transport mechanism), and includes any information delivery media. According to one aspect, the term "modulated data signal" describes a signal that has one or more characteristics set or changed in a manner that encodes information in the signal. By way of example and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), infrared, and other wireless media.

[0044] Figure 2 A flowchart of an operating system hibernation method 200 according to an embodiment of the present invention is shown. The method 200 is suitable for execution in a computing device 100, and the method 200 includes steps S210 to S290. Through the method 200, when the operating system is in hibernation, the swap space can be automatically expanded according to the size of the data in the memory to ensure the normal hibernation function of the operating system.

[0045] First, step S210 is executed to detect whether the operating system sleep condition is met. The sleep condition is pre-set by the user or by the system default, which is not limited. Setting the sleep time is a prior art and will not be described here. All methods for setting the sleep time are within the protection scope of the present invention.

[0046] When the computing device detects that the operating system hibernation condition is reached, step S220 is continued to be executed to obtain the size of the swap space existing in the computing device and the size of the current memory, where the current memory size is the size of the data in the current memory. Then step S230 is executed to determine whether the swap space needs to be expanded based on the size of the current memory and the size of the existing swap space. Specifically, it is determined whether the size of the current memory is larger than the size of the existing swap space. If so, it means that the existing swap space cannot accommodate all the data in the current memory, so the swap space needs to be expanded. If not, it means that the existing swap space can accommodate all the data in the current memory, so the swap space does not need to be expanded at this time.

[0047] 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.

[0048] If the swap space needs to be expanded, then step S250 is performed to determine the size of the target swap space. The size of the target swap space can be determined by the user customizing the swap space size, or according to the current memory size and the physical memory size of the computing device.

[0049] In some embodiments, the step of determining the size of the target space by user-defining the swap space size includes: the user specifies the swap space size in the user interaction interface, and after the determination interface is triggered, the computing device responds to the operation of specifying the swap space size in the user interaction interface, obtains the size of the swap space specified by the user, and uses the size of the swap space specified by the user as the size of the target swap space.

[0050] In some embodiments, the step of determining the size of the target space according to the current memory size and the physical memory size of the computing device includes: determining whether the current memory size is larger than the physical memory size, if the current memory size is larger than the physical memory size, then the size of the target swap space is the product of the target coefficient and the current memory size, and the target coefficient is a value not less than 1. The size of the target coefficient can be set according to the hardware of the computing device, and the present invention is not limited to this. For example, the target coefficient can be any value between 1 and 2. When the current memory size is not larger than the physical memory size, the size of the target swap space is any value within the range of the current memory size and the physical memory.

[0051] After determining the size of the target swap space, continue to execute step S260, delete the existing swap space, and continue to execute step S270 to create a swap file of the same size as the target swap space as the target swap file. Specifically, first determine whether 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. If it is not smaller, it means that the remaining storage space is sufficient, then create a swap file of the same size as the target swap space 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, it means that the remaining storage space is insufficient, then it is impossible to create a swap file of the same size as the target swap space, that is, the swap file creation fails, and continue to execute step S210.

[0052] After the target swap file is successfully created, step S280 is executed to set the target swap file as the target swap space, which is equivalent to expanding the swap space.

[0053] In some implementations, the process of expanding the swap space is as follows: first, obtain the path of the existing swap space, update the path of the target swap space to the path of the target swap file, then format the target swap file as a swap file type, and finally activate the formatted target swap file to achieve the expansion of the swap space.

[0054] After the swap space is expanded, step S290 is continued to be executed to swap the memory data of the computing device into the target swap space to realize the hibernation of the operating system.

[0055] Thus, the automatic expansion of the swap space during the operating system hibernation process is realized. Whenever the operating system hibernation is detected, steps S210 to S290 need to be performed.

[0056] Figure 3 The structure block diagram of an operating system hibernation device 300 according to an embodiment of the present invention is shown. The device 300 comprises an acquisition module 310, a determination module 320, a swap space expansion module 330 and a hibernation module 340 which are coupled in sequence.

[0057] The acquisition module 310 is adapted to acquire the size of the swap space and the size of the current memory existing in the computing device when it is detected that the operating system hibernation condition is reached.

[0058] The determination module 320 is adapted to determine whether the swap space needs to be expanded according to the current memory size and the size of the existing swap space, and if the swap space needs to be expanded, determine the size of the target swap space.

[0059] The swap space expansion module 330 is adapted to delete the existing swap space and create a swap file of the same size as the target swap space as the target swap file, and is also adapted to set the target swap file as the target swap space.

[0060] The hibernation module 340 is adapted to swap memory data into a target swap space to implement hibernation of the operating system.

[0061] It should be noted that the working principle of the operating system hibernation device 300 is similar to that of the operating system hibernation method 200 .

[0062] From the above content, it can be seen that the operating system hibernation method provided by the present invention, when it is detected that the operating system hibernation condition is met, obtains the size of the swap space already existing in the computing device and the size of the current memory, and determines whether the swap space needs to be expanded according to the size of the current memory and the size of the existing swap space. When expansion is required, the existing swap space is deleted, a swap space of sufficient size is created, and the memory data of the computing device is swapped into the newly created swap space to realize the operating system hibernation. It can be seen that in the present invention, when the operating system is hibernating, the swap space is automatically expanded according to the size of the data in the memory to ensure the normal hibernation function of the operating system.
