Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a baseboard management controller adaptation method for a basic input and output system, a computer program product, a device and a computer-readable storage medium. Background Art

[0002] BIOS (Basic Input Output System) and BMC (Baseboard Management Controller) are essential functional modules on server devices. BIOS runs on the main CPU (Central Processing Unit) and is used to start the main system.

[0003] During the boot process, some information of BIOS needs to be output through BMC, and some information needs to be exchanged and transmitted with BMC. To complete these functions, BIOS needs to adapt the corresponding interface of BMC during the boot process to communicate normally. Currently, a set of BIOS code corresponding to a CPU platform can only adapt to one BMC. When preparing a device that can support multiple BMCs, it is necessary to set up multiple code branches for different BMCs separately, and then adapt the corresponding BMCs through different code branches, which greatly increases the workload of code maintenance and BIOS code version management.

[0004] It can be seen that how to improve the adaptation efficiency of the BIOS on the server to the baseboard management controller is a problem that technical personnel in this field need to solve. Summary of the invention

[0024] In one embodiment, it also includes:

[0025] In the case where the standard baseboard management controller identification information is inconsistent with the current baseboard management controller identification information, determining whether there is baseboard management controller identification information consistent with the standard baseboard management controller identification information in the preset resource pool;

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0059] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] It should be noted that BIOS runs on the main CPU and is used to start the main system. The BIOS stores the most important basic input and output programs of the computer, the self-test program after power-on, and the system self-startup program, and finally boots into the OS (Operating System). BMC is the basic core functional subsystem of the server, responsible for the server's hardware status management, operating system management, health status management, power consumption management and other core functions. The main CPU and BMC are connected through buses such as eSPI (Enhanced Serial Peripheral Interface), PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard), and USB (Universal Serial Bus). The connection between the CPU and BMC is as follows: Figure 1 shown.

[0061] The BIOS startup process requires some information interaction and transmission with the BMC. Therefore, the BIOS must first identify the BMC information and adapt the corresponding interface during the startup process in order to communicate normally. If the original equipment manufacturer wants the device to support multiple BMCs, it is necessary to pull out multiple code branches respectively and adapt the corresponding BMCs respectively, which not only increases the workload of code maintenance, but also increases the workload of BIOS code version management on the project. In view of this, an embodiment of the present invention provides a baseboard management controller adaptation method for a basic input and output system that can reduce the workload of code maintenance and BIOS code version management.

[0062] Next, a baseboard management controller adaptation method of a basic input / output system provided by an embodiment of the present invention is described in detail. Figure 2 A schematic flow chart of a baseboard management controller adaptation method of a basic input / output system provided by an embodiment of the present invention, the method is applied to a basic input / output system, and includes:

[0063] S110: in the initialization phase, obtaining the current baseboard management controller identification information in the intermediate storage medium; the current baseboard management controller identification information is written into the intermediate storage medium when the current baseboard management controller is started;

[0064] It should be noted that when the basic input / output system BIOS and the baseboard management controller BMC are powered on and started, the BMC will write its current baseboard management controller identification information to a preset position in the intermediate storage medium during the startup process. A preset number of byte spaces can be pre-divided in the intermediate storage medium, for example, 4 bytes of space can be divided to store the baseboard management controller identification information. The current baseboard management controller can write its current baseboard management controller identification information to a preset position in the intermediate storage medium, wherein the intermediate storage medium must ensure that both the BIOS and the BMC can access it normally. During the initialization stage of the BIOS startup process, the BIOS can read the current baseboard management controller identification information from the preset position in the intermediate storage medium.

[0065] S120: According to the current baseboard management controller identification information, determine a target adaptation algorithm corresponding to the current baseboard management controller identification information from pre-stored adaptation algorithms corresponding to different baseboard management controller identification information;

[0066] It can be understood that in the embodiment of the present invention, adaptation algorithms corresponding to different baseboard management controller identification information are pre-stored, and then after the BIOS reads the current baseboard management controller identification information from the intermediate storage medium, the current baseboard management controller identification information can be matched with the pre-stored adaptation algorithms corresponding to different baseboard management controller identification information, and then the target adaptation algorithm corresponding to the current baseboard management controller identification information is determined.

[0067] S130: Initializing and configuring the serial port corresponding to the current baseboard management controller using the target adaptation algorithm during the continued startup process, so as to communicate with the current baseboard management controller through the initialized and configured serial port.

[0068] In the embodiment of the present invention, the BIOS continues to start up, and during the continued startup process, the matched target adaptation algorithm is used to initialize and configure the serial port corresponding to the current baseboard management controller. After the serial port corresponding to the current baseboard management controller is initialized and configured, communication with the current baseboard management controller can be carried out through the initialized and configured serial port during the startup process.

[0069] Please refer to the following Figure 3 Based on the above embodiments, the embodiments of the present invention further illustrate and introduce the technical solution:

[0070] In one embodiment, the intermediate storage medium may be a logic device.

[0071] It can be understood that in order to better ensure that both BIOS and BMC can normally access the intermediate storage medium in the embodiment of the present invention, and even in the CPU hot start stage, both BIOS and BMC can normally access the intermediate storage medium, the intermediate storage medium in the embodiment of the present invention can use a logic device, such as a complex programmable logic device (Complex Programmable Logic Device, CPLD), wherein the CPLD is not powered off in the CPU hot start stage, thereby ensuring that the information written by the BIOS or BMC can be saved.

[0072] In actual applications, a preset number (e.g., 4) bytes can be allocated on the CPLD to store the identification information of the baseboard management controller BMC. The address space can be connected to the CPU and BMC through SMBUS (System Management Bus), so that the CPU can access the CPLD through the corresponding SMBUS bus, and the BMC can access the CPLD through the corresponding SMBUS bus. That is, during the startup process, the BMC can only write its own baseboard management controller identification information into the corresponding address space of the CPLD through the corresponding SMBUS bus.

[0073] In one embodiment, the process of acquiring the current baseboard management controller identification information in the intermediate storage medium in the initialization phase in S110 may include:

[0074] After the system management bus module initialization phase is completed, the current baseboard management controller identification information in the intermediate storage medium is obtained.

[0075] It should be noted that in actual applications, the order in which BIOS initializes hardware modules can be adjusted, and the initialization of the SMBUS (System Management Bus) module is placed before the initialization of the UART module. That is, during the BIOS startup process, the SMBUS (System Management Bus) module can be initialized first, and then the UART (Universal Asynchronous Receiver / Transmitter) module (also known as the communication serial port) can be initialized.

[0076] That is, after the BIOS is started, the SMBUS initialization of the SEC (Security Phase) is performed, and after the SMBUS initialization phase is completed, the BIOS can access the intermediate storage medium through the initialized SMBUS bus, and obtain the current baseboard management controller identification information written by the current baseboard management controller from the intermediate storage medium.

[0077] In one embodiment, the method may further include:

[0078] Pre-storing baseboard management controller identification information corresponding to baseboard management controllers of different models and adaptation algorithms corresponding to baseboard management controllers of different models in a preset resource pool;

[0079] It should be noted that in the embodiment of the present invention, a preset resource pool can be pre-established, and for different types of baseboard management controllers, baseboard management controller identification information corresponding to different types of baseboard management controllers is obtained, and adaptation algorithms corresponding to different types of baseboard management controllers are determined, and then different types of baseboard management controllers and corresponding adaptation algorithms are stored in correspondence, and different types of baseboard management controllers and corresponding baseboard management controller identification information are stored in correspondence. The baseboard management controller identification information may include a vendor identification code (also known as a Vender ID (Identity document)) and / or a device identification code (Device ID).

[0080] Accordingly, the process of determining the target adaptation algorithm corresponding to the current baseboard management controller identification information from the pre-stored adaptation algorithms corresponding to different baseboard management controller identification information in the above S120 according to the current baseboard management controller identification information may include:

[0081] Matching the current baseboard management controller identification information with each baseboard management controller identification information stored in a preset resource pool to determine whether there is target baseboard management controller identification information that is consistent with the current baseboard management controller identification information;

[0082] When target baseboard management controller identification information that is consistent with the current baseboard management controller identification information exists in the preset resource pool, a target adaptation algorithm corresponding to the target baseboard management controller identification information is acquired.

[0083] It should be noted that, in an embodiment of the present invention, the current baseboard management controller identification information obtained from the intermediate storage medium can be matched with the baseboard management controller identification information corresponding to different models of baseboard management controllers pre-stored in the baseboard manager control resource pool to determine whether there is target baseboard management controller identification information consistent with the current baseboard management controller identification information in each baseboard management controller identification information. If there is consistent target baseboard management controller identification information, it means that the current baseboard management controller is normal, and the preset resource pool stores a target adaptation algorithm corresponding to the current baseboard management controller, so that the corresponding target model is determined according to the determined target baseboard management controller identification information, and the target adaptation algorithm corresponding to the target signal is determined according to the target model, so that the target adaptation algorithm corresponding to the current baseboard management controller identification information can be determined more accurately, thereby ensuring that the BIOS better adapts to the corresponding BMC during the startup process.

[0084] In one embodiment, in the process of continuing the startup process in S30 above, using the target adaptation algorithm to initialize and configure the serial port corresponding to the current baseboard management controller, the method includes:

[0085] In the communication serial port initialization phase, the communication serial port is initialized by using a target adaptation algorithm, so that the startup log is sent to the current baseboard management controller through the initialized communication serial port;

[0086] After the communication serial port initialization phase is completed, the system continues to boot to the pre-extensible firmware interface initialization PEI phase to configure the high-speed serial computer expansion bus.

[0087] It is understandable that after obtaining the target adaptation algorithm, the corresponding communication serial port UART initialization phase can be jumped to according to the target adaptation algorithm, and the target algorithm is used in the communication serial port initialization phase to initialize the UART serial port corresponding to the current BMC through eSpI (Enhanced Serial Peripheral Interface) or LPC (Low Pin CountBus), so that the startup log can be sent to the current baseboard management controller through the initialized UART serial port. Of course, the serial port log printing of the BIOS during the startup process, the initial VGA (Video Graphics Array) startup image output, the serial port console, etc. can also be sent to the BMC through the UART serial port, and output by the BMC.

[0088] Among them, the LPC interface is a low-speed 33MHz bandwidth bus used to connect the CPU and peripheral devices. The biggest advantage of the LPC bus is that it only requires 7 signals and is easy to layout on the motherboard.

[0089] After the UART initialization phase is completed, the BIOS continues to boot. When booting to the PEI phase, the high-speed serial computer expansion bus (peripheral component interconnect express, PCIe) link is configured. After the configuration is completed, the CPU can communicate with the VGA (Video Graphics Array, video graphics array) / H2B (Host to BMC) device on the BMC side through the PCIe interface and PCIe bus, thereby realizing the communication interaction between the BIOS and the BMC. For example, the asset information of the device is sent to the BMC for easy management and display by the BMC.

[0090] In one embodiment, after the configuration of the high-speed serial computer expansion bus is completed, the method may further include:

[0091] Obtaining standard baseboard management controller identification information of the current baseboard management controller through a high-speed serial computer expansion bus;

[0092] comparing the standard baseboard management controller identification information with the current baseboard management controller identification information;

[0093] When the standard baseboard management controller identification information is consistent with the current baseboard management controller identification information, the input and output system is controlled to continue to start until the startup is completed.

[0094] It should be noted that after the high-speed serial computer expansion bus is configured, the BIOS can communicate and interact with the BMC through the PCIe bus, so the BIOS can directly obtain the baseboard management controller identification information on the current BMC through the PCIe bus. In the embodiment of the present invention, in order to distinguish the baseboard management controller identification information directly obtained by the BIOS through the PCIe bus from the current baseboard management controller identification information obtained by the BIOS from the intermediate storage medium, the baseboard management controller identification information directly obtained by the BIOS through the PCIe bus is called the standard baseboard management controller identification information, which can be represented by B, and the current baseboard management controller identification information obtained from the intermediate storage medium is represented by A. Then, the standard baseboard management controller identification information B is compared with the current baseboard management controller identification information A obtained from the intermediate storage medium. If A is the same as B, the BIOS continues to start until the BIOS startup is completed.

[0095] In one embodiment, the method may further include:

[0096] When the standard baseboard management controller identification information is inconsistent with the current baseboard management controller identification information, determining whether there is baseboard management controller identification information consistent with the standard baseboard management controller identification information in the preset resource pool;

[0097] When there is baseboard management controller identification information consistent with the standard baseboard management controller identification information in the preset resource pool, the standard baseboard management controller identification information is written to the location where the current baseboard management controller identification information is located in the intermediate storage medium to overwrite the current baseboard management controller identification information and trigger its own hot restart.

[0098] It should be noted that if A is different from B, it is further checked whether B is stored in the preset resource pool, that is, the standard baseboard management controller identification information can be compared with each baseboard management controller identification information in the preset resource pool to determine whether there is baseboard management controller identification information consistent with the standard baseboard management controller identification information in the preset resource pool. If there is consistent baseboard management controller identification information, it means that the current BMC is normal, but the current baseboard management controller identification information A written by the current BMC to the intermediate storage medium is inaccurate. At this time, the target baseboard management controller identification information B can be used as the basis, and the standard baseboard management controller identification information can be written to the location where the current baseboard management controller identification information is located in the intermediate storage medium, thereby using the standard baseboard management controller identification information. The information overwrites the current baseboard management controller identification information to ensure that the baseboard management controller identification information stored in the intermediate storage medium is accurate, and triggers a hot restart. The purpose of triggering the hot restart is to restart the BIOS, but the BMC will no longer restart. Therefore, after the BIOS hot restart, since the BMC has not restarted, the BMC will no longer write the baseboard management controller identification information to the intermediate storage medium. At this time, the intermediate storage medium stores the standard baseboard management controller identification information. Therefore, after the BIOS hot restart, it will return to S110 to execute the step of obtaining the current baseboard management controller identification information in the intermediate storage medium in the initialization phase, and re-determine the accurate target configuration algorithm, and adapt the BMC during the startup process to ensure the accuracy of the adaptation.

[0099] In one embodiment, the method may further include:

[0100] When there is no baseboard management controller identification information consistent with the standard baseboard management controller identification information in the preset resource pool, marking the current baseboard management controller with an abnormal identification;

[0101] In the case where it is detected that the current baseboard management controller carries an abnormal flag during the remaining startup process, the interaction process with the current baseboard management controller is skipped and the startup continues.

[0102] It should be noted that, if the preset resource pool does not contain baseboard management controller identification information that is consistent with the standard baseboard management controller identification information, it means that the current baseboard management controller has an exception. The current baseboard management controller can be further marked with an exception mark, such as setting the BMC exception flag global variable, and the BIOS continues to start. In the subsequent startup process, when the BOIS needs to interact with the current BMC, it can first check whether the current baseboard management controller carries an exception flag. If it is detected that the current baseboard management controller carries an exception flag, the interaction process with the current BCM is skipped and the startup continues, thereby ensuring the normal startup of the BIOS when the BMC is abnormal.

[0103] In one embodiment, the method may further include:

[0104] The abnormal information of the current baseboard management controller and the standard baseboard management controller identification information are written into the intermediate storage medium in correspondence.

[0105] It is understandable that, in the case of determining that the current BMC is abnormal, after marking the BMC as abnormal, the abnormal mark and the standard baseboard management controller identification information of the current BMC can also be written into the intermediate storage medium in correspondence with each other, which is different from the address space used to store the current baseboard management controller identification information written by the BMC. Of course, in actual applications, the BIOS can also obtain information such as the error type and error cause of the current BMC, and store the error type and error cause information in the intermediate storage medium in correspondence with the abnormal mark and the standard baseboard management controller identification information of the current BMC, and issue an error prompt, so that the staff can read the abnormal information related to the current BMC and the error type and error cause information from the intermediate storage medium in time according to the error prompt for analysis and problem location.

[0106] It can be seen that in the embodiment of the present invention, the adaptation algorithms corresponding to the identification information of different baseboard management controllers are pre-stored, and when the baseboard management controller is started, its own current baseboard management controller identification information will be written into the intermediate storage medium. The basic input and output system will read the current baseboard management controller identification information from the intermediate storage medium during the initialization stage of startup, and then match the corresponding target adaptation algorithm from the pre-stored adaptation algorithms corresponding to the identification information of each baseboard management controller according to the current baseboard management controller identification information, and then use the target adaptation algorithm to initialize and configure the serial port corresponding to the current baseboard management controller during the continued startup process, so that communication with the current baseboard management controller can be carried out through the initialized and configured serial port. During use, the present invention can automatically match the corresponding adaptation algorithm for different baseboard management controllers without setting a separate code branch, which can reduce the workload of code maintenance and management to a certain extent.

[0107] Another embodiment of the present invention provides a baseboard management controller adaptation method for a basic input and output system, please refer to Figure 4 , applied to a baseboard management controller, the method comprises:

[0108] S210: writing the current baseboard management controller identification information of the baseboard management controller into the intermediate storage medium in the startup phase, so that the basic input and output system obtains the current baseboard management controller identification information in the intermediate storage medium in the initialization phase, and determines the target adaptation algorithm corresponding to the current baseboard management controller identification information from the pre-stored adaptation algorithms corresponding to different baseboard management controller identification information according to the current baseboard management controller identification information, and uses the target adaptation algorithm to initialize and configure the serial port corresponding to the baseboard management controller during the process of the basic input and output system continuing to start up;

[0109] S220: Communicate with the basic input and output system through the initialized and configured serial port.

[0110] In one embodiment, the method may further include:

[0111] After the communication serial port of the basic input and output system is initialized by using a target adaptation algorithm in the communication serial port initialization phase, a startup log sent by the basic input and output system is obtained through the communication serial port, and the startup log is stored.

[0112] It should be noted that after the BMC in the embodiment of the present invention is connected to the CPU, the system is powered on to the BIOS and the BMC is powered on to start. During the BMC startup process, the current baseboard management controller identification information will be written to the preset position in the intermediate storage medium. A preset number of byte spaces can be pre-divided in the intermediate storage medium, for example, 4 bytes of space can be divided to store the baseboard management controller identification information. The current baseboard management controller can write its current baseboard management controller identification information to the preset position of the intermediate storage medium, wherein the intermediate storage medium must ensure that both the BIOS and the BMC can access it normally. During the initialization stage of the BIOS startup process, the BIOS can read the current baseboard management controller identification information from the preset position in the intermediate storage medium.

[0113] In the embodiment of the present invention, adaptation algorithms corresponding to different baseboard management controller identification information are pre-stored, and then after the BIOS reads the current baseboard management controller identification information from the intermediate storage medium, the current baseboard management controller identification information can be matched with the pre-stored adaptation algorithms corresponding to the different baseboard management controller identification information, and then the target adaptation algorithm corresponding to the current baseboard management controller identification information is determined. In the embodiment of the present invention, the BIOS continues to boot, and during the continued booting process, the matched target adaptation algorithm is used to initialize and configure the serial port corresponding to the current baseboard management controller. After the serial port corresponding to the current baseboard management controller is initialized and configured, the current baseboard management controller can be communicated with through the initialized and configured serial port during the booting process.

[0114] It is understandable that the embodiment of the present invention can automatically match corresponding adaptation algorithms for different baseboard management controllers during use without the need to set code branches separately, which can reduce the workload of code maintenance and management to a certain extent.
