Memory isolation multiplexing method and device, equipment and storage medium

Abstract

The invention discloses a memory isolation multiplexing method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining memory isolation identification data in a starting process; analyzing the memory isolation identification data to obtain an isolation address corresponding to the target memory; performing read-write isolation processing on a memory space corresponding to the isolation address in the target memory; according to the method, the memory isolation identification data is used for recording the isolation address before restarting, the modified address is obtained again in the starting process, read-write isolation is carried out, reuse of the isolation address is achieved, the isolation address does not need to be detected again, and efficiency is improved.

Description

technical field [0001] The present application relates to the field of memory technologies, and in particular, to a memory isolation multiplexing method, a memory isolation multiplexing device, an electronic device, and a computer-readable storage medium. Background technique [0002] ECC (Error Checking and Correcting: Error Checking and Correcting) is a memory technology that is widely used in physical memory modules in the server field. The purpose is to detect errors in reading and writing data in memory and correct them. In the actual production environment, the user mode program and the kernel system program will frequently access the memory during the working process, and the accessed physical memory will cause the memory CE (Corrected error, correctable error) due to hardware failure or other reasons. ). Memory isolation is achieved by marking the address of the faulty physical memory page (usually at the OS (Linux) system layer) to achieve the effect of no longer b...

AI Technical Summary

Problems solved by technology

Memory isolation is achieved by marking the address of the faulty physical memory page (usually in the OS (Linux) system layer) to achieve the effect of no longer being allocated for use. When the server restarts, the last fault isolation record becomes invalid, making it necessary to re-detect and isolate it again , less efficient
