FIG. 2 is a flow chart of a memory processing method in one embodiment. The memory processing method in this embodiment is described by taking the electronic device in fig. 1 as an example. As shown in fig. 2, the memory processing method includes steps 202 to 206.

Step 202, obtaining a memory page identifier set corresponding to a currently running application program.

The currently running application program refers to an application program in a current running state, and specifically may include at least one of a foreground application and a background application. The memory page identification set is used for storing the identification corresponding to the memory page. The foreground application refers to an application in which a user is operating on the electronic device, and the background application refers to an application which is not operated by the user but is also running in the background of the electronic device.

Specifically, the electronic device may obtain the currently running application program, and obtain the set of memory page identifiers corresponding to the currently running application program. The memory page identification set is used for recording the identification of the memory page corresponding to the currently running application program.

In one embodiment, the set of memory page identifiers is used to record the identity of memory pages used by the currently running application.

In one embodiment, under the condition that the foreground application is changed, the electronic device may acquire the currently running application program, and acquire a memory page identifier set corresponding to the currently running application program.

Step 204, determining a foreground application and a background application in the currently running application program.

Specifically, the electronic device may determine a foreground application and a background application that are currently running from the currently running application programs, respectively.

In one embodiment, the electronic device may determine a foreground application and a background application in the currently running application program by running the task list. The electronic equipment can acquire an operation task list in a preset duration, and a foreground application and a background application in the currently operated application program are determined through the operation task list. The electronic equipment can acquire a group of lists of recently operated tasks, the recently used applications are ordered in time, the most recently used applications are arranged at the forefront, namely the forefront applications, and the rest applications are background applications.

In one embodiment, the electronic device may obtain an application process information list running on itself, and determine a foreground application and a background application in the currently running application program according to the application process information list. When the process contains background running codes, judging that the application program corresponding to the process is background application. When a certain process in the application process information list is in a display state of the forefront interface, judging that an application program corresponding to the process is a foreground application.

For example, when the foreground application is switched from the application program a to the application program B, and the application program a enters the background to continue to run, the application program a and the application program B serve as the currently running application programs, and the application program B serves as the foreground application, and the application program a serves as the background application.

Step 206, obtaining a foreground memory page identifier corresponding to the foreground application in the memory page identifier set, and adjusting the priority of the foreground memory page corresponding to the foreground memory page identifier; the priority of the adjusted foreground memory page is higher than that of the background memory page of the background application.

The foreground memory page identifier refers to an identifier of a memory page corresponding to a foreground application, and the foreground memory page refers to a memory page corresponding to the foreground application. The background memory page refers to a memory page corresponding to a background application.

Specifically, the priority refers to a priority of memory usage. The electronic device may obtain a foreground memory page identifier corresponding to the foreground application from the set of memory page identifiers. The electronic device may determine a foreground memory page corresponding to the foreground memory page identifier, and adjust a priority of the foreground memory page to improve the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than a priority of a background memory page of a background application.

In one embodiment, the electronic device may further obtain a background memory page identifier corresponding to the background application from the memory page identifier set. The background memory page identifier refers to the identifier of the memory page corresponding to the background application. The electronic device can determine the background memory page corresponding to the background memory page identifier, and the electronic device can adjust the priority of the foreground memory page to improve the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, a memory page identifier set corresponding to a currently running application program is obtained, and a foreground application and a background application in the currently running application program are determined, so that the currently running application program can be divided into a foreground application and a background application. The method comprises the steps that foreground memory page identifiers corresponding to foreground applications in a memory page identifier set are obtained, the memory pages of the foreground applications and the memory pages of the background applications can be distinguished, the priority of the foreground memory pages corresponding to the foreground memory page identifiers is adjusted, the priority of the foreground memory pages can be improved, and the adjusted priority of the foreground memory pages is higher than that of the background memory pages of the background applications. By improving the priority of the foreground memory page, the foreground application can obtain higher memory use priority, and the foreground application has lower delay and higher response speed.

In one embodiment, obtaining a foreground memory page identifier corresponding to a foreground application in a memory page identifier set, and adjusting a priority of a foreground memory page corresponding to the foreground memory page identifier, includes:

The active linked list is used for storing frequently accessed memory pages in an active state. The inactive linked list is used to store memory pages that may be associated with one or more processes, but are not frequently used.

Specifically, the electronic device obtains a foreground memory page identifier corresponding to a foreground application from the memory page identifier set. The electronic equipment determines a foreground memory page corresponding to the foreground memory page identifier, and determines a linked list where the foreground memory page is located. The linked list includes an active linked list and an inactive linked list. Active linked lists use memory with a higher priority than inactive linked lists.

When the foreground memory page is in the inactive linked list, indicating that the foreground memory page is placed in the queue which is not accessed frequently, the electronic device moves the foreground memory page to the active linked list, thereby moving the foreground memory page to the queue which is accessed frequently.

In one embodiment, the electronic device may determine each foreground memory page within the inactive linked list, and move each foreground memory page from the inactive linked list to the active linked list.

In one embodiment, the list is an LRU (LEAST RECENTLY Used ) list, which is divided into an active list and an inactive list. The active link list is denoted as active link list and the inactive link list is denoted as inactive link list.

In this embodiment, the priority of the active linked list is higher than that of the inactive linked list, and the foreground memory page corresponding to the foreground application is placed in the active linked list, so that the foreground memory page can be placed in the frequently accessed queue, thereby improving the priority of the foreground application in using the memory, and reducing the number of times of repeated loading errors of the page of the foreground application. The page repeated loading error (Foreground Aware Eviction Scheme, abbreviated as FAE) refers to a process of loading a page to a memory for the first time, releasing the memory space of the page after a period of non-access, and then generating a page missing interrupt again when the page is accessed again, so that related data needs to be read from the external memory to the memory again. The time difference between reading the external memory and directly reading the internal memory is very large, which can lead to response delay of the application. In this embodiment, by increasing the priority of using the memory by the foreground application, the number of page repeated loading errors of the foreground application is reduced, so that the starting speed of the foreground application can be increased.

In one embodiment, the method further comprises: and under the condition that the foreground memory page is in the active linked list, the foreground memory page is reserved in the active linked list.

And judging whether the foreground memory pages are in the active linked list or not according to each foreground memory page. And under the condition that the foreground memory page is in the active linked list, the foreground memory page is not moved so as to keep the foreground memory page in the active linked list.

In this embodiment, when the foreground memory page is in the active linked list, the foreground memory page is kept in the active linked list, so that the foreground memory page is kept in the frequently accessed queue, and the priority of the foreground application for using the memory can be improved, so that the memory response of the foreground application is improved, and the user experience of the foreground application is improved.

In one embodiment, the method further comprises: obtaining a background memory page identifier corresponding to a background application in a memory page identifier set, and adjusting the priority of the background memory page corresponding to the background memory page identifier; the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page.

Specifically, the electronic device may obtain a foreground memory page identifier corresponding to the foreground application from the memory page identifier set. The electronic device may determine a foreground memory page corresponding to the foreground memory page identifier, and adjust a priority of the foreground memory page to increase the priority of the foreground memory page.

And the electronic equipment can also acquire the background memory page identifier corresponding to the background application from the memory page identifier set. The electronic device can determine the background memory page corresponding to the background memory page identifier, and the electronic device can adjust the priority of the background memory page to reduce the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the adjusted priority of the background memory page.

In one embodiment, the electronic device may determine a foreground memory page corresponding to the foreground memory page identifier and a background memory page corresponding to the background memory page identifier, and the electronic device may obtain priorities of the foreground memory page and the background memory page, and compare the priorities of the foreground memory page and the background memory page. And under the condition that the priority of the foreground memory page is lower than that of the background memory page, adjusting the priority of the foreground memory page to improve the priority of the foreground memory page so that the priority of the foreground memory page is higher than that of the background memory page.

In one embodiment, in the case that the priority of the foreground memory page is lower than the priority of the background memory page, the electronic device may adjust the priority of the background memory page to reduce the priority of the background memory page, so that the priority of the foreground memory page is higher than the priority of the background memory page.

In one embodiment, in the case that the priority of the foreground memory page is lower than the priority of the background memory page, the electronic device may adjust the priorities of the foreground memory page and the background memory page at the same time, so as to increase the priority of the foreground memory page and decrease the priority of the background memory page, so that the priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, the background memory page identifier corresponding to the background application in the memory page identifier set is obtained, so that the background memory page being used by the background application can be quickly and accurately searched through the background memory page identifier. The priority of the background memory page corresponding to the background memory page identification is adjusted, so that the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page, and by improving the priority of the foreground memory page, the foreground application obtains higher memory use priority, the background application obtains lower memory use priority, the requirement of the background application on the memory can be reduced, and the memory response of the foreground application is improved.

Specifically, the electronic device obtains a background memory page identifier corresponding to a background application from the memory page identifier set. The electronic equipment determines a background memory page corresponding to the background memory page identifier, and determines a linked list in which the background memory page is located. The linked list includes an active linked list and an inactive linked list. Active linked lists use memory with a higher priority than inactive linked lists.

And carrying out the same processing on each background memory page so as to move each background memory page in the active linked list to the inactive linked list.

In this embodiment, the priority of the active linked list is higher than the priority of the inactive linked list. For the background memory pages in the active linked list, the background memory pages are moved to the inactive linked list, and the background memory pages can be moved to the queue which is not frequently accessed, so that the priority of the background application for using the memory is reduced, and the starting speed of the foreground application can be accelerated.

In one embodiment, the method further comprises: and under the condition that the background memory pages are in the inactive linked list, the background memory pages are reserved in the inactive linked list.

In one embodiment, the method further comprises: and determining a clean memory page in the inactive linked list, and recycling the clean memory page.

The clean memory page refers to an unmodified memory page in the memory space, and the clean memory page may be one or more memory pages.

In one embodiment, the method further comprises: and determining a clean memory page and a dirty memory page in the inactive linked list, and recycling the clean memory page and the dirty memory page in sequence based on the priority of the clean memory page being higher than that of the dirty memory page.

In this embodiment, the clean memory pages are preferentially recovered, so that the memory recovery efficiency can be improved.

Specifically, in the case where the currently running application program is divided into a foreground application and a background application, the application identification of the application program is divided into a first application identification and a second application identification, respectively. The first application identifier refers to an application identifier corresponding to a foreground application, and the second application identifier refers to an application identifier corresponding to a background application. After the electronic device determines the currently running application, a foreground application and a background application in the currently running application may be determined. The electronic device may obtain a first application identifier corresponding to the foreground application and a second application identifier corresponding to the background application.

Specifically, the electronic device performs matching processing on the first application identifier and each memory page identifier in the memory page identifier set to determine a memory page identifier matched with the first application identifier. And the electronic equipment judges the memory page identifier matched with the first application identifier in the memory page identifier set as a foreground memory page identifier. According to the same processing mode, the electronic device can screen out each foreground memory page identifier matched with the first application identifier from the memory page identifier set.

The application identifier refers to a unique identifier configured by the electronic device for its own application program, for example, if the electronic device installs an application program a, an application program B and an application program C, the electronic device may allocate different application identifiers for the application program a, the application program B and the application program C respectively. The application identifier and the memory page identifier of the same application program have a corresponding relationship. For example, the application A is identified as A, the memory page corresponding to the application A is identified as A-1, and multiple memory pages of the application A may use the same memory page identifier, or may use different memory page identifiers, such as A-1, A-2, A-3, etc.

In particular, in the event that an update exists for its own application, the electronic device may determine that an updated application exists. Application presence updates refer to the downloading of a new application or the updating of a version of an original application in an electronic device.

① The electronic equipment downloads the application program or carries out version update on the application program installed in the electronic equipment;

② When the electronic equipment installs the application program, the electronic equipment updates a configuration file of the application program through a system framework, and the configuration file records the allocated application identification. The application identifier may be stored in a Page Table Entry (PTE) and corresponds to the application package name. When the application program runs, the application identifier of the application program to which the mark belongs in the memory page is used as the memory page identifier of the memory page. In one embodiment, the electronic device uses an android operating system on which applications run.

③ ④ Is executed when a foreground application of the electronic device changes.

④ The system framework determines a foreground application currently running and transmits an application identifier of the foreground application.

⑤ The Kernel foreground aware removal mechanism may obtain application identifiers of all application programs of the electronic device by accessing the configuration file. In one embodiment, the Kernel may obtain an application identifier corresponding to a currently running application program through a foreground aware removal mechanism.

⑥ The Kernel accesses the configuration file of the foreground application through the foreground perception removal mechanism, and obtains the application identification of the foreground application from the configuration file.

The foreground perception removing mechanism can dynamically obtain an application identifier of a foreground application, identify a foreground memory page of the foreground application through the application identifier, and then adjust priorities of the foreground memory page of the foreground application in an active linked list and an inactive linked list, so that the priority of the foreground application using the memory is improved.

FIG. 5 is a schematic diagram illustrating the adjustment of the priority of memory pages according to one embodiment. The electronic device adjusts the priority of the memory pages through the active linked list and the inactive linked list. The priority of the active linked list is higher than the priority of the inactive linked list. When the memory page identifier corresponds to the application identifier of the foreground application, the memory page corresponding to the memory page identifier is indicated to be the foreground memory page. And when the memory page identifier corresponds to the application identifier of the background application, the memory page corresponding to the memory page identifier is indicated to be the background memory page.

When a memory page in the active linked list or inactive linked list is accessed, the electronic device may determine whether the accessed memory page is a foreground memory page or a background memory page.

And under the condition that the accessed memory page is a background memory page and the background memory page is in the active linked list, the electronic equipment moves the background memory page to the inactive linked list. And when the accessed memory page is a background memory page and the background memory page is in the inactive linked list, the background memory page is reserved in the inactive linked list.

And under the condition that the accessed memory page is a foreground memory page and the foreground memory page is in the inactive linked list, the electronic equipment moves the foreground memory page to the active linked list. And under the condition that the accessed memory page is a foreground memory page and the foreground memory page is in the active linked list, the electronic equipment keeps the foreground memory page in the active linked list.

And the electronic equipment recovers the memory page from the tail part of the inactive linked list, and when the memory page is a clean memory page, the electronic equipment recovers the clean memory page through a recovery process. When the memory page is a dirty memory page, the dirty memory page is written back to the head of the inactive linked list from the tail of the inactive linked list.

Through the memory processing of the implementation, the memory allocation recovery priority of the foreground application and the background application is adjusted, the probability that the memory pages of the foreground application and the background application are recovered in the system can be reduced, the memory requirement of the background application for the memory can be reduced, and the memory response of the foreground application can be improved, so that the user experience of the foreground application can be improved.

In one embodiment, a memory processing method is provided, including:

The electronic device downloads the application or updates the installed application.

When an application is installed, the electronic device configures an application identifier for the installed application.

Then, the electronic device configures a memory page identifier corresponding to the application identifier for the updated memory page of the application program.

When the foreground application is changed, the electronic equipment acquires a memory page identification set corresponding to the currently running application program.

Then, the electronic equipment determines a foreground application and a background application in the currently running application program, and acquires a first application identifier of the foreground application and a second application identifier of the background application.

Further, the electronic device determines a foreground memory page identifier that matches the first application identifier from the set of memory page identifiers.

Then, the electronic device determines a linked list in which the foreground memory page corresponding to the foreground memory page identifier is located.

Optionally, the electronic device moves the foreground memory page to the active linked list if the foreground memory page is in the inactive linked list; under the condition that the foreground memory page is in the active linked list, the electronic equipment keeps the foreground memory page in the active linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

Optionally, from the memory page identifier set, the electronic device determines a background memory page identifier matched with the second application identifier, and determines a linked list where a background memory page corresponding to the background memory page identifier is located.

And under the condition that the background memory page is in the active linked list, the electronic equipment moves the background memory page to the inactive linked list.

Optionally, in a case where the background memory page is in the inactive linked list, the electronic device retains the background memory page in the inactive linked list.

Further, the electronic device retrieves the memory page from the tail of the inactive linked list, and when the memory page is a clean memory page, the electronic device retrieves the clean memory page through a retrieval process. When the memory page is a dirty memory page, the dirty memory page is written back to the head of the inactive linked list from the tail of the inactive linked list.

In this embodiment, a unique application identifier is configured for each application program, and when the application program runs, a memory page identifier corresponding to the memory page identifier of the application program is applied. When the foreground application is changed, the identification of the memory page corresponding to the currently running application program is recorded through the memory page identification set, so that the foreground memory page corresponding to the foreground application and the background memory page corresponding to the background application are accurately determined according to the corresponding relation between the application identification and the memory page identification.

The priority of the active linked list is higher than that of the inactive linked list, and the foreground memory pages can be moved from the inactive linked list to the active linked list, so that the foreground memory pages can be moved to a frequently accessed queue. Under the condition that the foreground memory page is in the active linked list, the foreground memory page is reserved in the active linked list so as to be reserved in the frequently accessed queue, the priority of the foreground application for using the memory can be improved, the number of times of repeated loading errors of the page of the foreground application is reduced, and therefore the starting speed of the foreground application can be increased.

For the background memory pages in the active linked list, the background memory pages are moved to the inactive linked list, but the background memory pages in the inactive linked list are not moved, so that the background memory pages can be completely placed in a queue which is not frequently accessed, the priority of using the memory by the background application can be reduced, and the starting speed of the foreground application can be accelerated.

And by recycling the clean memory pages in the inactive linked list, the usable memory space can be increased, and the normal operation of the application program is ensured.

It should be understood that, although the steps in the flowcharts of fig. 2-3 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2-3 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the sub-steps or stages are performed necessarily occur in sequence, but may be performed alternately or alternately with at least a portion of the other steps or sub-steps of other steps.
