Problems solved by technology

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

Abstract

The invention discloses a method for obtaining CPU (central processing unit) register information. The method comprises the following steps: a basal plate management controller transmits a command toa target CPU through a PECI (platform environment control interface) agreement, and the command is a command for receiving the CPU register information; the target CPU is used for returning data, which comprise the CPU register information, to the basal plate management controller through the PECI agreement according to the command so as to enable the basal plate management controller to store theCPU register information. The PECI agreement is adopted by the method to enable the basal plate management controller and a CPU to directly perform data interaction so as to obtain the CPU register information. Therefore, the problem that the basal plate management controller waits for a long time is avoided, the occupied memory is reduced, the efficiency of obtaining the CPU register informationis improved, and the hardware resource and cost are saved as well. Correspondingly, a system, equipment and computer readable storage medium disclosed by the invention have the technical effects as well.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a method, system, device and computer-readable storage medium for acquiring CPU register information. Background technique [0002] 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. [0003] 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 syste...
