红帽全球峰会第 32 章 使用高级错误报告
当您使用 高级错误报告 (AER)时，您会收到 Peripheral Component Interconnect Express (PCIe)设备的错误事件通知。RHEL 默认启用此内核功能，并收集内核日志中报告的错误。如果您使用 rasdaemon 程序，这些错误会被解析并存储在其数据库中。
32.1. AER 概述
复制链接链接已复制到粘贴板!
高级错误报告 (AER)是一个内核功能，可为 Peripheral Component Interconnect Express (PCIe)设备提供增强的错误报告。AER 内核驱动程序附加在支持 PCIe AER 功能的 root 端口，以便：
- 收集全面的错误信息
- 向用户报告错误
- 执行错误恢复操作
当 AER 捕获到错误时，它会将向控制台发送一条 错误 消息。对于可修复的错误，控制台输出是一条 警告。
