Processing method and device for memory management metadata

Abstract

The embodiment of the application discloses a processing method and a device for memory management metadata, which are used for processing memory management metadata efficiently. The method comprisesthe following steps: calling mmap to allocate memory management metadata memory, wherein the memory management metadata memory is a huge page large page memory; establishing The physical address mapping table, and the physical address mapping table and storing the physical page frame number of the memory management metadata memory corresponding to each memory management metadata; and storing the physical page frame number of the memory management metadata memory by the physical address mapping table corresponding to each memory management metadata. In response to a request to access the targetmemory management metadata, adopting a physical address mapping table to look up a physical page frame number of a memory management metadata memory corresponding to the target memory management metadata, and the target memory management metadata is any memory management metadata, so as to realize access to the target memory management metadata.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to a method and device for processing memory management metadata. Background technique [0002] Memory management refers to the allocation and use of device memory resources when the code is running. In the storage system, generally based on Linux memory management, a layer of memory management module is provided through the Linux kernel module to implement more flexible memory management methods such as power failure protection. In the implementation process of this method, a lot of memory management metadata is needed, and memory management metadata needs to be used in the memory management process. The prior art lacks a method for effectively processing these memory management metadata. Summary of the invention [0003] In view of this, the embodiments of the present application provide a method and device for processing memory management metadata, so as to realize more efficient...
