Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0019] For the operating system, because the size of the memory itself is limited, memory recycling is a more common mechanism. There are two main reasons for memory reclamation: the system needs to provide enough memory for any sudden memory request at any time, so that the use of cache and other related memory will not cause the remaining memory of the system to remain in a very long period of time. less state. Also, when an application larger than free memory arrives, memory recycling w...

Abstract

The embodiment of the invention discloses a memory recovery method and device, electronic equipment and a storage medium. The method comprises the following steps: in response to a memory recovery instruction, obtaining an identifier of a to-be-recovered memory page, and the identifier is used for representing the type of the memory page; if it is detected that the to-be-recycled memory page is aforeground page based on the identifier, protecting the to-be-recycled memory page; and if it is detected that the to-be-recycled memory page is not the foreground page based on the identifier, recycling the to-be-recycled memory page. Through the method, when the memory page is recycled, whether the to-be-recycled memory page is the foreground page or not is judged firstly, and if the to-be-recycled memory page is the foreground page, the to-be-recycled memory page is protected, so that the number of times of recycling the memory page is reduced, and then jamming of a process due to reallocation of the memory page can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a memory recovery method, device, electronic equipment, and storage medium. Background technique [0002] Memory, also known as main memory, is a storage space that the CPU can directly address and is made of semiconductor devices. The memory space in the electronic device is limited. In order to ensure that the system has enough memory to use, the system of the electronic device usually performs memory recovery under certain circumstances. However, in the related memory recovery method, after the memory page is recovered, the memory page needs to be reallocated, which may cause the process to be stuck due to the reallocation of the memory page. Contents of the invention [0003] In view of the above problems, the present application proposes a memory reclamation method, device, electronic equipment and storage medium to improve the above problems. [000...
