摘　　要：为解决国产计算模块启动过程中出现偶发性故障时因无日志记录导致后续故障分析困难的问题,提出了一种国产计算模块固件上电日志记录技术。该技术利用板级管理单元采集计算模块从按下电源开关模块上电开机到UEFI固件启动完成这段过程的日志信息,并将日志信息存储在板级存储单元中,解决了国产计算模块从上电到UEFI固件启动完成这一阶段无日志记录难题,同时通过对日志输出进行去冗分类、统一标识输出日志、按阶段分级输出等手段设计了固件上电日志输出格式,完成了日志记录、导出、解析、展示和故障分析。完成了软硬件设计,并进行试验验证,通过设计故障注入进行验证,该系统能够有效的记录计算模块的固件上电日志,有助于国产计算模块偶发性故障定位分析。To address the problem of difficulty in subsequent fault analysis due to the lack of log records when experiencing rare failures in the domestic computing module during start-up,a domestic computing module firmware power-on log recording technology is proposed.This technology utilizes the board-level management unit to collect log information about the computing module powering on from pressing the power supply switch module to the completion of the UEFI firmware boot process,and stores the log information in the board-level storage unit.This solves the problem of not having a log record during the stage from power-on to UEFI firmware boot completion in domestic computing modules.Meanwhile,through means such as deleting redundant records,unifying the output of log records,and grading the output of log records,the firmware power-on log output format is designed,and the log recording,export,parsing,display,and fault analysis are completed.The software and hardware design have been completed,and experimental verification has been conducted.The system has been verified through designing fault injection,and it can effectively record the power-on log of the computing module,which is helpful for the positioning and analysis of rare failures in domestic computing modules.
