Abstract

The invention discloses a memory management method and device suitable for a slab structure. The memory management method applicable to the slab structure comprises the following steps: monitoring thestate of a slab memory block; and when it is determined that the state of the slab memory block is not allocated, directly submitting the unallocated slab memory block to a page allocator for management. The memory management method and device disclosed by the invention can simplify the memory management operation suitable for the slab structure and improve the efficiency.

Description

technical field [0001] The invention relates to a computer system, in particular to a memory management method and device suitable for a slab structure. Background technique [0002] The memory capacity of a computer system is usually limited, but many computer applications can run on the same computer system. In order to ensure that different computer applications use the system memory efficiently, it is necessary to effectively manage the system memory. a key technology. [0003] At present, most computer systems use a double-layer memory management structure to manage system memory. Such as figure 1 As shown, the page allocator 101 is a first-level memory management structure, and it usually manages system memory with a memory page (a memory block with a storage capacity of 4K bytes) as a basic unit, so as to allocate memory for applications such as file systems / drivers. dedicated cache (in figure 1 This relationship is shown in the form of arrow 105). The slab alloc...
