Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Currently, in the EGS platform, because the CPU Prochot pin is designed as a unidirectional input pin, the CPLD can only obtain the ambient temperature near the CPU detected by the VR chip, and then determine whether to trigger the CPU Prochot signal according to the ambient temperature near the CPU. Therefore, the VR chip detects that the ambient temperature near the CPU is delayed from the core temperature of the CPU, so that the BMC cannot acquire the CPU Prochot state through the CPLD in time and trigger an alarm in time.
Therefore, the CPU state monitoring scheme can realize accurate CPU state monitoring and can accurately realize abnormal state warning, and operation and maintenance personnel can adjust a heat dissipation strategy or troubleshoot faults in time.
Referring to fig. 1, an embodiment of the present invention discloses a method for monitoring a state of a central processing unit, which is applied to a baseboard management controller, and specifically includes:
step S11: reading the current state information of the central processing unit recorded in a preset register inside the central processing unit through a special single-wire bus which is in communication connection with the central processing unit in advance, and locally storing the current state information.
In this embodiment, the current temperature state information of the central processing unit recorded in the preset register inside the central processing unit is read through a platform environment type control interface that establishes communication connection with the central processing unit in advance, and the current temperature state information is locally stored. It can be understood that the BMC periodically reads the value of bit0 in the CPU Package Thermal Status register through the PECI, where bit0 in the register is a bit representing the Prochot state of the CPU, where 1 represents in the Prochot state, and 0 represents in the normal state, and stores the temperature state information to the local.
Step S12: and judging whether the current state information is consistent with the last state information of the central processing unit stored locally.
In this embodiment, it is determined whether the current state information is consistent with the last state information of the cpu stored locally, and if the current temperature state information is consistent with the last temperature state information of the cpu stored locally, the corresponding abnormal state alarm is not performed or the abnormal state alarm is released, and the platform environment type control interface that establishes communication connection with the cpu in advance is executed, the current temperature state information of the cpu recorded in a preset register inside the cpu is read, and the current temperature state information is stored locally. It will be appreciated that the comparison is made from the read current temperature state information to the last temperature state information stored locally, for example: detecting the value of bit0 in the current CPU Package Thermal Status register, then taking out the last temperature state information from the local for comparison, comparing the value of bit0 read this time with the value of bit0 read last time, if the value of bit0 read currently is 0, the value of bit0 read last time is 0, the comparison result is consistent, the temperature in the CPU at two times belongs to the normal state, and the BMC does not need to report; if the value of the bit0 bit read currently is 1 and the value of the bit0 bit read last time is 1, the comparison results are consistent, the temperature in the CPU at two times belongs to an abnormal state, and the CPU is still in a temperature alarm state at the moment, so that the temperature in the CPU is not changed all the time, and the BMC does not need to report.
Step S13: and if the current state information is inconsistent with the last state information, performing corresponding abnormal state alarm or removing the abnormal state alarm according to a preset abnormal state alarm rule.
In this embodiment, in an implementation manner, if the current temperature state information is inconsistent with the last temperature state information of the cpu stored locally, and the current temperature state information is temperature abnormal state information, a temperature abnormal state reporting instruction is triggered, and an alarm log generated in a temperature abnormal state is recorded by the substrate management controller, and a corresponding temperature abnormal state alarm is performed. It can be understood that when the value of bit0 in the current CPU Package Thermal Status register is detected to be 1, and the value of bit0 stored last time is 0, it indicates that the temperature state of the CPU detected last time is a normal state, and the temperature state of the CPU detected currently is an abnormal state, the temperature state information of the previous time and the temperature state information of the next time are inconsistent, and the current temperature state is an abnormal state, which indicates that after the Prochot trigger/release of the CPU for a complete cycle, a temperature state abnormal reporting instruction is triggered, and the BMC needs to record an alarm log and perform corresponding abnormal state alarm.
In another embodiment, if the current temperature state information is inconsistent with the last temperature state information of the central processing unit stored locally, and the current temperature state information is temperature normal state information, the abnormal state alarm is released according to an abnormal state alarm rule. It can be understood that, when the value of bit0 in the current CPU Package Thermal Status register is detected to be 0, and the value of bit0 stored last time is 1, it indicates that the CPU temperature state detected last time is an abnormal state, and the CPU temperature state detected currently is a normal state, the temperature state information of the previous time and the temperature state information of the next time are inconsistent, and the current temperature state is a normal state, at this time, because bit0 of the CPU Package Thermal Status register is in an oscillation state, an abnormal state alarm cannot be immediately released, and whether a state alarm is released needs to be further determined based on an abnormal state alarm rule.
Further, the present application may also monitor a CPU ERROR state, where the CPU ERROR state may specifically include but is not limited to: an IERR (internal Error), Processor Disabled (Processor corruption), UCE (non-Processor Machine Check Exception), CE (Processor recoverable Error), and the like.
Therefore, the application discloses a method for monitoring the state of a central processing unit, which is applied to a substrate management controller and comprises the following steps: reading the current state information of the central processing unit recorded in a preset register inside the central processing unit through a special single-wire bus which is in communication connection with the central processing unit in advance, and locally storing the current state information; judging whether the current state information is consistent with the last state information of the central processing unit stored locally; and if the current state information is inconsistent with the last state information, performing corresponding abnormal state alarm or removing the abnormal state alarm according to a preset abnormal state alarm rule. Therefore, the method and the device have the advantages that the current state information of the central processing unit can be directly acquired through the special single-line bus which is in communication connection with the central processing unit in advance, the accurate current state information of the central processing unit can be acquired, the good service performance and the prolonged service life of the central processing unit can be maintained, meanwhile, the problems of downtime of a server and the like caused by high temperature of the central processing unit are avoided as much as possible, and the method and the device have objective economic benefits. And then corresponding abnormal state alarm or abnormal state alarm release is carried out according to a preset abnormal state alarm rule, so that the condition of mistakenly releasing the alarm can be effectively prevented.
Referring to fig. 2 and fig. 3, the embodiment of the present invention discloses a specific method for monitoring the state of a central processing unit, and compared with the previous embodiment, the present embodiment further describes and optimizes the technical solution. Specifically, the method comprises the following steps:
step S21: reading the current temperature state information of the central processing unit recorded in a preset register inside the central processing unit through a platform environment type control interface which is in communication connection with the central processing unit in advance, and locally storing the current temperature state information.
In this embodiment, the PECI is used to read the current temperature state information of the central processing unit recorded in the preset register inside the central processing unit, and locally store the current temperature state information, it can be understood that the PECI is used to directly read the current temperature state information of the central processing unit recorded in the preset register inside the central processing unit, instead of using the CPLD to detect the ambient temperature near the central processing unit, and the VR chip is used to detect the ambient temperature near the central processing unit, so that the BMC can timely and accurately obtain the Prochot state of the central processing unit through the PECI.
Step S22: and judging whether the current temperature state information is consistent with the last temperature state information of the central processing unit stored locally.
Step S23: detecting and recording the system time of the server when the central processing unit is in an abnormal temperature state each time; and if the current temperature state information is inconsistent with the last temperature state information of the central processing unit stored locally and the current temperature state information is temperature normal state information, calculating the time difference between the system time of the current server and the system time of the server when the last temperature of the central processing unit is abnormal state information.
In this embodiment, the system time of the server when the central processing unit is in the abnormal temperature state each time is detected and recorded, for example: when detecting that the value of bit0 of the CPU Package Thermal Status register is 1, recording and storing the system time of the server; if the current temperature state information is inconsistent with the last temperature state information of the central processing unit stored locally, such as: when not _ value is not equal to last _ value, and it is detected that the value of bit0 of the CPU Package Thermal Status register is 0, that is, the current temperature state information is temperature normal state information, at this time, since the CPU core temperature just rises to the prochot threshold value, the bit0 is in a vibration state, that is, the value repeatedly jumps between 0 and 1, in order to prevent false cancellation of an abnormal state alarm, a time difference between the system time of the current server and the system time of the server when the last temperature of the central processing unit is abnormal state information needs to be calculated, and then whether the abnormal state alarm is cancelled is determined.
Step S24: and selecting whether to remove the abnormal state alarm or not according to the time difference and the temperature state information of the central processing unit detected by a temperature sensor arranged in the voltage regulator.
In this embodiment, a relationship between a time difference between a current system time of the server and a recorded last time when bit0 of the CPU Package Thermal Status register is 1 and a preset time difference is compared, and in one embodiment, when the time difference is smaller than the preset time difference, an operation of removing an abnormal state alarm is not performed, and a step of executing the platform environment type control interface which establishes communication connection with the central processing unit in advance, reading current temperature state information of the central processing unit recorded in the preset register inside the central processing unit, and locally storing the current temperature state information is performed. It can be understood that the preset time difference is 20s, if the time difference is 13s, the time difference is smaller than the preset time difference time _ now-time _ last < 20s, which indicates that bit0 of the CPU Package Thermal Status register is in an oscillation state at this time, the abnormal state alarm cannot be released, and the method continues to jump to execute the platform environment type control interface which establishes communication connection with the central processing unit in advance, reads the current temperature state information of the central processing unit recorded in the preset register inside the central processing unit, and locally saves the current temperature state information.
In another embodiment, if the time difference is greater than a preset time difference and the cpu temperature status information detected by a temperature sensor built in the voltage regulator is normal temperature status information, the bmc records a log generated in a normal temperature status and releases an abnormal status alarm. It can be understood that the preset time difference is 20s, if the time difference is 26s, time _ now-time _ last is greater than 20s and is greater than the preset time difference, at this time, auxiliary judgment needs to be performed according to the ambient temperature state near the central processing unit detected by a temperature sensor built in a VR chip, and if the VR chip detects that the ambient temperature near the central processing unit is also in a normal temperature state, a log generated in the normal temperature state is recorded by a BMC and an abnormal state alarm is released; and if the VR chip detects that the ambient temperature near the central processing unit is in an abnormal temperature state, the abnormal state alarm is not removed.
Therefore, the embodiment of the application can read the bit0 value of the CPU Package Thermal Status register through the PECI, and can accurately monitor the internal Prochot state of the CPU in real time. The method solves the problem that the BMC of the EGS platform cannot monitor the high-temperature alarm of the core temperature of the CPU of the server, is quicker than the original method of reading the transmission signal of the Prochot pin through the CPLD in a transparent way, can report the abnormal state alarm more timely to the administrator by the abnormal state alarm or timely and accurately removing the abnormal state alarm, is beneficial to operation and maintenance personnel to adjust the heat dissipation strategy or troubleshoot the fault in time, is beneficial to maintaining the good service performance of the CPU and prolonging the service life, avoids the problems of shutdown of the server and the like caused by the high temperature of the CPU as much as possible, and has objective economic benefit.
Referring to fig. 4, an embodiment of the present invention discloses a central processing unit status monitoring apparatus, including:
the information reading module 11 is configured to read current state information of the central processing unit recorded in a preset register inside the central processing unit through a dedicated single-wire bus that is in communication connection with the central processing unit in advance, and locally store the current state information;

and the state monitoring module 13 is configured to perform corresponding abnormal state alarm or remove the abnormal state alarm according to a preset abnormal state alarm rule if the current state information is inconsistent with the previous state information.
Therefore, the application discloses a method for monitoring the state of a central processing unit, which is applied to a substrate management controller and comprises the following steps: reading the current state information of the central processing unit recorded in a preset register inside the central processing unit through a special single-wire bus which is in communication connection with the central processing unit in advance, and locally storing the current state information; judging whether the current state information is consistent with the last state information of the central processing unit stored locally; and if the current state information is inconsistent with the last state information, performing corresponding abnormal state alarm or removing the abnormal state alarm according to a preset abnormal state alarm rule.
