Abstract

The embodiment of the invention provides a page bumping protection method and device for operating system memory recovery. The method comprises the steps that UE conducts data collection on multiple application scenes to obtain a bumping page data set; the UE solves an intersection set of all elements in the bumping page data set to obtain a page set list_thrashining_common which bumps in the plurality of application scenes; a summation set of all elements in the bumping page data set is solved to obtain a set list_thrashining_all of all bumping pages; and the UE carries out protection on thelist_thrashing_common and the list_thrashing_all by taking a block as a basic unit. The technical scheme provided by the invention has the advantage of high user experience.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a page thrashing protection method and device for operating system memory reclamation. Background technique [0002] The android system (linux kernel) adopts the principle of "usable and usable, reclaimed when busy" for memory. The recovery of memory caused some frequently used file pages to be scanned twice in a row, so that the activity quickly decreased to INACTIVE, and was finally recycled to the buddy system. Subsequent applications access the corresponding location of the file, so that the action of allocating physical pages / reading file content occurs again. Generally, this process is called page thrashing. [0003] Excessive page thrashing will lead to system performance degradation, affect user usage, and reduce user experience. Contents of the invention [0004] The embodiment of the present application discloses a page thrashing protection meth...
