Method and device for recording high-temperature log on SOC and medium

Abstract

The embodiment of the invention discloses a method and device for recording a high-temperature log on an SOC and a computer readable storage medium. A CPLD judges whether a thermal disconnection signal is received or not; taking a low level as an effective level as an example, since the continuous pull-down time of the thermal circuit break signal on the SOC system is short, the BMC can detect thepin level of the thermal circuit break signal at an interval of a long time, and the BMC can realize the collection of log information only when the pin level is the low level. Therefore, in the technical scheme, when the CPLD receives the thermal disconnection signal, a preset delay program is called to perform delay processing on the thermal disconnection signal, so that the level of the pin where the thermal disconnection signal is located can be kept at a low level for a long time, and the BMC can conveniently and smoothly record the log information of CPU high-temperature alarm. By prolonging the duration of the thermal disconnection signal, the problem that the SOC system cannot smoothly collect log information when a CPU gives an alarm at a high temperature is effectively solved.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a method, a device and a computer-readable storage medium for recording a high temperature log on an SOC. Background technique [0002] The power consumption and temperature of a central processing unit (Central Processing Unit, CPU) increase continuously as the running speed increases. How to make the CPU run safely, improve the reliability of the system, and prevent crashes, blue screens, repeated restarts, and even CPU burnout caused by overheating are not only the dilemma faced by the CPU, but also an important issue for motherboard designers. [0003] For this reason, Intel took the lead in proposing the concept of Thermal Monitor, which greatly increases the stability and safety by controlling the temperature of the CPU and protecting it from overheating. When the internal temperature of the CPU exceeds the set temperature such as 80 degrees Celsius, a PROCHOT ...

AI Technical Summary

Problems solved by technology

[0004] After the Thermal_trip is triggered on the Intel purely platform CPU, the signal will always be pulled low, and both CPLD and BMC can receive it, so as to realize shutdown and log recording, but after being triggered on the Intel SOC Denverton platform CPU, Thermal_trip will only be pulled low for 60us, and then becomes high, the server can only be shut down, but the BMC fails to record the log
