Abstract

The invention discloses a memory recovery method and device, and belongs to the technical field of memory management. The memory recovery method comprises the steps that a plurality of memory resource groups are established, and each memory resource group corresponds to at least one application program of the electronic equipment; under the condition that the used memory of the electronic equipment reaches a target memory threshold value, the memory of the memory resource group is recycled through a target kernel thread, and the target kernel thread is a kernel thread used for page recycling.

Description

technical field [0001] The present application belongs to the technical field of memory management, and in particular relates to a memory recovery method and device. Background technique [0002] Electronic devices have brought great convenience to our life and work, and there are more and more scenarios where electronic devices are used in daily work. The speed of memory recovery is an important guarantee for the fluency of electronic devices. Native systems usually use one thread for memory recovery, and perform memory recovery according to the remaining memory capacity, but the memory recovery rate of a single thread is not fast; in order to improve the memory recovery rate, currently it will use Multiple threads do memory recycling, but although multiple threads reclaim memory quickly, there is serious lock competition, which can easily lead to performance degradation, which in turn leads to problems such as freezes and splash screens on electronic devices in scenarios w...
