AI Technical Summary
Technical Problem
When a process in PA mode uses physical memory addresses, a correctable memory error can occur, causing the process to crash or the system kernel to freeze.
Method used
By obtaining the physical address where the correctable error occurred, it is determined whether it is occupied by a process in PA mode. If it is occupied, the address is not isolated and data error correction is performed. The automatic recovery ECC processing mechanism or memory mirror redundancy mechanism is used for data error correction.
Benefits of technology
It avoids isolating the physical address of the process in PA mode, ensuring the normal operation of the process, improving memory availability and extending memory lifespan, and preventing process errors and system kernel crashes.

Abstract
本申请公开了一种内存故障处理方法、装置、设备及可读存储介质。本申请在内存发生可修正错误时，首先获取发生可修正错误的物理地址，进而判断该物理地址是否被PA模式的进程占用，若该物理地址被PA模式的进程占用，则不隔离该物理地址，并对该物理地址进行数据纠错，以使该物理地址能够正常被使用，当然PA模式的进程也能够正常使用该物理地址，避免引发进程出错或系统内核宕机等问题。相应地，本申请提供的一种内存故障处理装置、设备及可读存储介质，也同样具有上述技术效果。
