Abstract

The invention discloses a memory fault processing method and device, computing equipment and a storage medium, and belongs to the technical field of storage. The method comprises the following steps: applying to allocate a plurality of virtual memory blocks, and recording a virtual address of each virtual memory block, the virtual address corresponding to a physical address of a physical memory block; determining a faulty physical memory block in the physical memory; marking the virtual address corresponding to the physical address of the faulted physical memory block as unavailable; after receiving the write request, not allocating and marking the virtual address marked as an unavailable write request. The faulted physical memory block can be processed, and the running stability of the computing equipment is ensured.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a memory fault processing method and device, computing equipment, and storage media. Background technique [0002] In a computing device, the memory is a component that provides data cache to the processor. When an application program accesses the faulty memory, the operating system will stop responding to the application program, which will cause the operating system to crash and affect the stability of the operating system. . Therefore, discovering and handling the failure of the memory in time can prevent the application program from accessing the failed memory, thereby ensuring the stability of the operation of the operating system. Wherein, the memory includes multiple physical memory blocks, and an uncorrectable error (uncorrect error, UCE) may occur in the physical memory block. [0003] In related technologies, when an application program fails to acces...
