Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1 . FIG. 1 is a flowchart of a computer system self-checking method according to an embodiment of the present invention. The method can include:

Step 101: When the computer system starts, the processor obtains the whole machine self-check program stored in the preset non-volatile storage medium before entering the operating system; wherein, the processor and the BMC are connected to the preset non-volatile memory through the IO switch. The storage medium communication connection, the IO switch does not turn on the communication connection between the preset non-volatile storage medium and the processor and the BMC at the same time;

It can be understood that the purpose of this step can be that when a computer system such as a server is started, the processor (such as the host CPU) in the computer system is turned on by the IO switch before entering the operating system (OS). The communication connection between the volatile storage medium and the processor is used to obtain the complete machine self-checking program that is stored in the preset non-volatile storage medium and required to perform the complete machine inspection of the computer system.

Specifically, the specific content of the whole machine self-checking program in this step can be set by the designer according to the usage scenarios and user needs. For example, the whole machine self-checking procedure may include a program for checking various components in the computer system, such as the CPU , the pressure test program of memory and hard disk, and the pressure test program of other components; the self-check program of the whole machine may also include the health state detection program of various components, etc., which is not limited in this embodiment. The self-checking program of the whole machine can be set according to the models of different computer systems, and is stored in the preset non-volatile storage medium of the computer system when the whole machine of the computer system leaves the factory.

Correspondingly, this embodiment does not limit the specific device type of the preset non-volatile storage medium for storing the self-checking program of the whole machine in the computer system. For example, the preset non-volatile storage medium may be a TF card (also known as microSD, a Very small flash memory card), can also be SD (Secure Digital card, secure digital card) card, can also be other types of non-volatile storage such as EMMC (embedded Multi Media Card, embedded multimedia memory card) card medium.

It should be noted that, in this embodiment, in order to save costs and facilitate the management of the self-checking program of the whole machine in the preset non-volatile storage medium and the storage of other data in the preset non-volatile storage medium, the preset non-volatile The storage medium can communicate with the processor and the BMC (Baseboard Management Controller) in the computer system respectively. For example, the SD signal of the processor and the BMC is connected to the same preset non-volatile storage medium, so that the processor and the BMC can Share a preset non-volatile storage medium (such as SD card) without the need to configure a separate SD card for the processor and BMC.

Further, in this embodiment, in order to avoid a signal conflict when both the processor and the BMC are connected to the preset non-volatile storage medium for communication, as shown in FIG. ) communicates with the preset non-volatile storage medium (TF card or SD card), and the IO switch does not turn on the communication connection between the preset non-volatile storage medium and the processor and the BMC at the same time. Set the data sharing in the non-volatile storage medium to avoid signal conflict. That is, only the processor or the BMC can access the preset non-volatile storage medium at the same time through the IO Expander (IO expansion) that controls the conduction of the IO switch switching signal. The strobe signal of the IO Expander can be placed on the processor or BMC; if it is placed on the processor, the processor initiates signal switching; if the strobe signal is placed on the BMC, the BMC controls the signal switching, and the BMC needs to provide a switching interface command (such as IPMI command) for the processor to call, that is, the processor communicates with the BMC to send the switch interface command. As shown in Figure 2, the processor can send the switch interface command to the BMC through the LPC (Low pin count Bus) channel to realize the IO Expander. control of the strobe signal.

Correspondingly, when the strobe signal of the IO Expander is placed on the BMC, that is, when the BMC directly controls the signal switching of the IO switch, in this step, before the processor obtains the whole machine self-check program stored in the preset non-volatile storage medium, The BMC can control the IO switch to turn on the communication connection between the processor and the preset non-volatile storage medium, and turn off the communication connection between the BMC and the preset non-volatile storage medium, so as to ensure that the processor can pass through the communication connection with the preset non-volatile storage medium. The connected communication connection can obtain the self-checking program of the whole machine stored in the preset non-volatile storage medium. For example, through the monitoring program design of the BMC, when the BMC detects the startup signal of the computer system, it controls the IO switch to turn on the communication connection between the processor and the preset non-volatile storage medium, and turns off the BMC and the preset non-volatile storage medium. wherein, the startup signal of the computer system may include a normal startup signal when the host is normally started and/or a restart signal when the host is restarted. Before entering the operating system, the processor can send a switching interface command to the BMC through the communication connection with the BMC, so that the BMC controls the IO switch to turn on the communication connection between the processor and the preset non-volatile storage medium, and turns off the BMC and the BMC. Preset communication connections for non-volatile storage media. This embodiment does not impose any limitation on this.

Correspondingly, when the strobe signal of the IO Expander is placed on the processor, before the processor enters the operating system, it controls the IO switch to turn on the communication connection between the processor and the preset non-volatile storage medium, and turns off the BMC and the preset non-volatile storage medium. Communication connections for volatile storage media.

Specifically, the specific method for the processor to obtain the self-checking program of the whole machine stored in the preset non-volatile storage medium in this step can be set by the designer, for example, in order to facilitate the processor to obtain and check the self-checking program of the whole machine. Use, the preset non-volatile storage medium can be replaced with a self-starting partition (ie, self-starting partition) corresponding to the self-diagnosis system. When the computer system needs to be self-checked, the processor enters the operating system when During the previous BIOS startup process, the self-starting partition can be recognized, and can be guided into the self-diagnosis system, so as to obtain the self-checking program of the whole machine in the self-starting partition.

Correspondingly, in this step, before the processor obtains the whole-machine self-checking program stored in the preset non-volatile storage medium, it may further include a step of the processor judging whether to carry out the whole-machine self-checking of the computer system; if so, enter this step The processor acquires the whole machine self-checking program stored in the preset non-volatile storage medium; if not, the processor can directly enter the operating system.

Specifically, this embodiment does not limit the specific manner in which the processor determines whether to perform the self-check of the computer system. For example, the user can control whether the computer system performs the self-check by selecting the startup device when the host of the computer system enters the BIOS; When the computer system is required to perform self-checking, the self-booting partition of the preset non-volatile storage medium can also be set as the default booting item through the control commands (such as IPMI command and Restful command) provided by the BMC; that is, the processor can judge by Whether the boot item contains the self-boot partition for booting the preset non-volatile storage medium or not, determines whether to carry out the self-check of the computer system.

Step 102: Run the whole-machine self-checking program to check the computer system as a whole to obtain the self-checking result.

It can be understood that the purpose of this step may be that the processor performs a complete machine inspection of the computer system by running the whole machine self-inspection program in the preset non-volatile storage medium, thereby obtaining a self-inspection result.

In order to facilitate the user to view the self-test results, in this embodiment, after the processor obtains the self-test results, the self-test results can be stored in the preset non-volatile storage medium in the form of files, so that the subsequent BMC can store the self-test results from the preset non-volatile storage medium. Self-test results are obtained from volatile storage media.

Further, in order to facilitate the subsequent acquisition of the self-test results stored in the preset non-volatile storage medium by the BMC, the processor can directly or through the BMC control the IO switch to turn on the communication connection between the BMC and the preset non-volatile storage medium, and turn off the communication connection between the BMC and the preset non-volatile storage medium. The communication connection between the processor and the preset non-volatile storage medium is disconnected. For example, when the processor runs the whole machine self-check program to complete the self-check, the whole machine self-check program can notify the BMC to switch the IOExpander back to the BMC, so that the BMC can directly obtain the self-check result from the preset non-volatile storage medium.

Correspondingly, in this embodiment, after the processor stores the self-test results in the preset non-volatile storage medium, the BMC can obtain the test results from the preset non-volatile storage medium, and generate a log corresponding to the test results, so as to store the self-test results. The inspection results are displayed to users in the form of logs, so that users can remotely view the self-inspection results through remote control of the BMC. For example, the BMC can regularly check the self-test results in the preset non-volatile storage medium, and display the self-test results to customers in the form of logs. Further, the BMC can generate alarm events such as SEL and SNMP Trap to notify the user of the self-check result by means of an alarm, so that the user can check the self-check result in time.

Step 103: After the whole machine self-checking program is completed, enter the operating system.

Specifically, the purpose of this step may be that the processor completes the self-checking program of the whole machine while running, enters the operating system, and realizes the normal startup of the computer system.

In this embodiment, the embodiment of the present invention uses the whole machine self-check program stored in the preset non-volatile storage medium to automatically complete the whole machine check of the computer system before entering the operating system by the processor in the computer system, which can avoid Manual participation; and a preset non-volatile storage medium that stores the self-check program of the corresponding model can be directly configured during the production of the computer system, so that various models can be flexibly adapted, easy to batch self-check, improve The user experience is improved; and the communication connection between the preset non-volatile storage medium and the processor and the BMC is not turned on at the same time through the IO switch, so that the processor and the BMC can share the preset non-volatile storage medium on the basis of avoiding signal conflicts. , to ensure the communication effect and reduce the hardware cost.
