CPU寄存器是中央处理器(CPU)内的重要组成部分，可以同时被内部电路和外部电路或者软件访问，是具有有限存储容量的高速存储部件，用来暂存指令、数据和地址。通常包括：指令寄存器(IR)、程序计数器(PC)、累加器(ACC)等。The CPU register is an important part of the central processing unit (CPU), which can be accessed by internal circuits and external circuits or software at the same time. It is a high-speed storage unit with limited storage capacity and is used to temporarily store instructions, data and addresses. Usually include: instruction register (IR), program counter (PC), accumulator (ACC) and so on.
在服务器调试或者上线维护过程中，不可避免地会出现服务器系统黑屏、系统宕机或者系统启动异常等问题，故需要收集中央处理器内的相关CPU寄存器信息以查找问题根源，解决系统问题。In the process of server debugging or online maintenance, problems such as black screen of the server system, system downtime, or abnormal system startup will inevitably occur. Therefore, it is necessary to collect relevant CPU register information in the central processing unit to find the root cause of the problem and solve the system problem.
目前，在获取CPU寄存器信息时，一般是基板管理控制器通过南桥芯片与CPU取得联系，获取CPU寄存器信息。具体过程为：基板管理控制器通过南桥芯片上的ME发送相关的Bridge命令，ME需要通过PECI接口从CPU上获取寄存器信息返回给基板管理控制器；其中，南桥芯片作为基板管理控制器和CPU之间的消息中转方。在该过程中，基板管理控制器等待的时间较长，且CPU寄存器信息的数据量巨大，整个过程耗时较长，占用了基板管理控制器的系统内存，造成基板管理控制器系统运行缓慢，极易造成基板管理控制器系统的崩溃宕机。At present, when obtaining CPU register information, generally the baseboard management controller contacts the CPU through the south bridge chip to obtain the CPU register information. The specific process is: the baseboard management controller sends relevant Bridge commands through the ME on the south bridge chip, and the ME needs to obtain the register information from the CPU through the PECI interface and return it to the baseboard management controller; among them, the south bridge chip is used as the baseboard management controller and Message transfer party between CPUs. In this process, the baseboard management controller waits for a long time, and the data volume of the CPU register information is huge. The whole process takes a long time, occupies the system memory of the baseboard management controller, and causes the baseboard management controller system to run slowly. It is very easy to cause the crash and downtime of the baseboard management controller system.
因此，如何快速获取CPU寄存器信息，减少基板管理控制器的等待时间，是本领域技术人员需要解决的问题。Therefore, how to quickly obtain CPU register information and reduce the waiting time of the baseboard management controller is a problem to be solved by those skilled in the art.
