DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0014] It should be noted that, in the description of this application, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0015] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] With the rise of AI technology and cloud services, the use of servers is increasing. The problem of server power consumption needs to be solved urgently. It is important in many aspects. Specifically, it is analyzed from the following aspects: (1) Operating costs: Power consumption directly determines the electricity consumption of the server during operation. Data centers usually have a large number of servers, and electricity costs are an important part of their operating costs. The higher the power consumption of the server, the more electricity bills need to be paid; high-power servers usually require more powerful cooling systems to ensure their stable operation, which will increase the hardware procurement and installation costs.

[0017] (2) Performance and stability: Power consumption is closely related to server performance. To a certain extent, improving server performance often requires increasing power consumption, but if power consumption is too high, it may cause the server to overheat, leading to performance degradation. Excessive power consumption will cause server hardware to be in a high-temperature environment for a long time, accelerating hardware aging and damage, and reducing the service life and stability of the server. For example, high temperature can cause the metal interconnect structure of electronic components to migrate, resulting in circuit short circuits or open circuits, increasing the probability of server failure.

[0018] (3) Business expansion and planning: Servers with lower power consumption generate relatively less heat. When the space in the computer room is limited, servers can be deployed more densely to improve the utilization rate of the computer room space. For some data centers with limited space, this can expand the business scale and increase the number of servers deployed to meet the needs of business growth without increasing too much site costs.

[0019] (4) Power capacity planning: Lower server power consumption means that during the construction and operation of a data center, the capacity demand for the power supply system is relatively low. This can reduce the investment and upgrade costs of power infrastructure and reduce the pressure on power supply. When planning a data center, a reasonable assessment of server power consumption will help accurately plan power capacity and avoid limiting business development due to insufficient power supply.

[0020] (5) Environment and sustainability: With the rapid development of information technology, the number of servers is increasing and their energy consumption is also rising. Reducing server power consumption can improve the utilization efficiency of energy resources.

[0021] Therefore, it is particularly important to meet the business needs of servers while saving power consumption to the maximum extent.

[0022] In order to solve at least one of the above technical problems, an embodiment of the present application proposes a configuration method of a central processing unit (CPU), which adjusts the CPU configuration without changing the CPU entity, thereby optimizing the CPU's operating power consumption while meeting business requirements and reducing application costs. The method is described in detail below in conjunction with the execution flow of the configuration method of the central processing unit.

[0023] Figure 1 A flowchart of a method for configuring a central processing unit provided in an embodiment of the present application.

[0024] like Figure 1 As shown, the configuration method of the central processing unit of the embodiment of the present application includes the following steps: S1, receiving the configuration trigger instruction from the central processor; S2, in response to the configuration trigger instruction, reading target configuration information of the central processor from the external memory, wherein the target configuration information is within a preset allowable configuration range so as to be stored in the external memory; S3, configuring the central processing unit according to the target configuration information.

[0025] Specifically, the CPU is the computing core and control core of the computer, and is mainly responsible for interpreting and executing computer instructions, processing data, and controlling the operation of other hardware devices. The configuration trigger instruction of the CPU can be a power-on trigger or a configuration instruction sent by the user, etc., without specific limitation.

[0026] The external memory is a storage unit after receiving the target configuration information. Figure 2As shown, after the BMC (Baseboard Management Controller) receives the target configuration information, it compares the target configuration information with the preset allowable configuration range. If the configuration data of the target configuration information is within the preset allowable configuration range, the target configuration information is sent to the external memory for storage, so that the information can be called when the configuration trigger instruction is received later. The preset allowable configuration range can be set according to the hardware parameters of the central processing unit to ensure that the configured central processing unit can be used normally. The external memory can be a dynamic random access memory (DRAM), a static random access memory (SRAM), etc., which can be defined according to actual needs.

[0027] After receiving the configuration trigger instruction, this embodiment obtains the target configuration information from the external memory according to the configuration trigger instruction, and sends the target configuration information to the central processor, so that the central processor can perform parameter configuration according to the target configuration information, thereby performing custom configuration of the central processor based on customer needs, and achieving the technical effect of reducing power consumption and application costs while meeting application requirements. In addition, by storing the target configuration information received by the BMC in the external memory, data stability and data security can be further improved.

[0028] In one embodiment of the present application, the target configuration information includes target power and / or target number of cores.

[0029] Specifically, the power and core of the central processing unit (CPU) are two closely related concepts, which together determine the performance and power consumption of the CPU. Among them, the power of the CPU usually refers to its thermal design power consumption (TDP). TDP refers to the power consumption of the CPU when it reaches maximum load under standard working conditions, usually in watts (W). The core of the CPU refers to the physical processing unit inside the CPU. Each core can perform tasks independently. A multi-core CPU has multiple cores, which can process multiple tasks in parallel, thereby improving the overall processing power. The number of cores directly affects the multi-tasking capability of the CPU. For multi-core CPUs, they usually have 4 cores, 6 cores, 8 cores or even more cores, which enables them to handle complex tasks and multi-threaded applications more efficiently. The number of cores is also one of the important factors affecting the power consumption of the CPU. More cores mean more processing units working at the same time, which leads to higher power consumption.

[0030] During the configuration of the central processing unit, the CPU power consumption can be configured separately, in which case the target configuration information only includes the target power; the number of CPU cores can be configured separately, in which case the target configuration information only includes the target number of cores; the CPU power consumption and the number of CPU cores can also be configured at the same time, in which case the target configuration information includes the target power and the target number of cores to meet the needs of different application scenarios.

[0031] In the case where the target configuration information includes the target power, the target power can limit the total power upper limit of the CPU operation, or it can be matched to the operating power in each CPU core, thereby limiting the power upper limit of each CPU core. In a multi-core CPU, multiple processor cores are integrated into one chip, and each core is an independent processing unit that can perform different tasks at the same time. Therefore, the amount of tasks for each CPU core is different. Therefore, the target power can also be used to limit the operating power of a certain CPU core in a targeted manner, such as raising the power upper limit of the CPU core with higher computing requirements based on the application scenario, or lowering the upper limit of the CPU core with lower computing requirements based on the application scenario. In addition, the power can be set differently in combination with the relative position of each CPU core and the heat sink, that is, the CPU core close to the heat sink, that is, the area with better heat dissipation effect, is given a higher power upper limit, and the CPU core relatively far from the heat sink, that is, the area with poor heat dissipation effect, is given a lower power upper limit to avoid the occurrence of local overheating.

[0032] When the target configuration information includes the target number of cores, the central processing unit can determine the number of CPU cores in working state according to the target number of cores, thereby controlling the CPU cores and planning reasonable application paths and function implementations.

[0033] Therefore, this embodiment can flexibly set the target power and / or target number of cores based on application requirements to match the application scenario without changing the CPU entity, improve the rationality of resource utilization, and reduce the CPU's operating power consumption.

[0034] In one embodiment of the present application, the external memory is a general flash memory storage area of ​​a programmable logic device.

[0035] Specifically, a programmable logic device (PLD) is a general-purpose integrated circuit whose logic functions are defined by user programming. It is suitable for the design and implementation of various digital systems, including programmable array logic (PAL), complex programmable logic device (CPLD), field-programmable gate array (FPGA), etc.

[0036] by Figure 2 For example, the target configuration information is received through the BMC. In order to avoid the failure of this key setting to take effect due to an abnormality in the BMC during operation, the target setting information is no longer passed to the BIOS (Basic Input Output System) every time through the BMC, but the setting information is passed to the BIOS by the CPLD (Complex Programmable Logic Device). That is, the BMC sends and stores the target configuration information in the UFM (Universal Flash Storage) area of ​​the CPLD. Among them, the BMC, as the management controller of the server, can realize the management and control of the server, including the power consumption management of the server.

[0037] Since the values ​​in the UFM area of ​​the CPLD will not disappear or change in the case of AC (Alternating Current), DC (Direct Current), or when the CPLD firmware is upgraded, the data is stable and will not be lost, ensuring that the target configuration information can be successfully retrieved when a configuration trigger command is received.

[0038] In one embodiment of the present application, before receiving the configuration trigger instruction of the central processing unit, it also includes: obtaining the initial configuration information of the central processing unit and the target configuration information of the central processing unit; when the target configuration information is different from the initial configuration information and the target configuration information is within a preset allowable configuration range, storing the target configuration information in an external memory.

[0039] Specifically, the initial configuration information of the CPU can be general configuration information defined based on the production line of the CPU, or can be factory general configuration information with custom settings. The preset allowable configuration range is the parameter configurable range determined based on the hardware configuration of the CPU.

[0040] by Figure 2For example, after each startup of the BIOS, the number of CPU cores and power consumption of the current CPU, that is, the initial configuration information, and the range of the number of cores and power consumption supported by the CPU, that is, the preset allowable configuration range, are sent to the BMC.

[0041] When the project is shipped, the package setting tool is used to set the CPU power consumption and number of CPU cores specified by the customer for the package, that is, the target configuration information, to the BMC, and then the BMC compares the received target configuration information with the initial configuration information. If the target configuration information is the same as the initial configuration information, the target configuration information received this time can be ignored to avoid repeating the configuration process. If the target configuration information is different from the initial configuration information, the target configuration information is further compared with the preset allowable configuration range. If the target configuration information is within the preset allowable configuration range, it is considered that the hardware configuration of the central processing unit is applicable to the target configuration information, and the target configuration information is sent to the UFM area of ​​the CPLD for storage, so as to facilitate data call when the configuration trigger instruction is received later. If the target configuration information is not within the preset allowable configuration range, it is considered that the hardware configuration of the central processing unit cannot meet the customer's customization requirements, an alarm is issued, and the target configuration information will not be sent to the UFM area of ​​the CPLD.

[0042] When receiving the target configuration information, this embodiment filters the target configuration information through the initial configuration information of the central processing unit and the preset allowed configuration range. On the one hand, it can avoid repeated configuration, and on the other hand, it can ensure that the hardware architecture of the central processing unit is compatible with the target configuration information, so as to improve the success rate of subsequent configurations and the actual application effect of the configured central processing unit.

[0043] Furthermore, when the target configuration information is the same as the initial configuration information, a synchronization reminder may be issued to notify the technician that the configuration has been completed, thereby avoiding repeated operations by the technician.

[0044] In one embodiment of the present application, the configuration method of the central processing unit further includes: in response to a viewing instruction of the central processing unit, displaying a preset allowed configuration range and initial configuration information.

[0045] Specifically, the viewing instruction can be received through the interactive screen, so that before the technician enters the target configuration information, the preset allowable configuration range and initial configuration information of the central processing unit can be viewed in advance through the display screen, so that the target configuration information can be entered based on the preset allowable configuration range and initial configuration information, thereby speeding up the input process of the target configuration information that meets the configuration operation and accelerating the configuration progress.

[0046] For example, the technician can check the preset allowable configuration range and the initial configuration information. If it is determined that the target configuration information customized by the customer is the same as the initial configuration information, the target configuration information does not need to be input at this time, and the configuration completed button is triggered to mark the current central processing unit as configured. If it is determined that one of the target configuration information customized by the customer is the same as the initial configuration information, such as the same number of CPU cores, only the target power can be input as the target configuration information at this time, thereby speeding up the configuration progress. In addition, when it is determined that the target configuration information is different from the initial configuration information, the target configuration information can be adjusted in advance with reference to the preset allowable configuration range. For example, when the target configuration information customized by the customer is outside the preset allowable configuration range, the target configuration information can be input without input. At this time, other servers can be selected according to the target configuration information customized by the user, so as to select the central processing unit that supports the target configuration information, realize autonomous selection operation, or seek other adjustment strategies, and adjust the target configuration information to the preset allowable configuration range on the premise of meeting the requirements of the customized application scenario, thereby avoiding the input of invalid target configuration information and data processing process.

[0047] In one embodiment of the present application, when the target configuration information is different from the initial configuration information and the target configuration information is within a preset allowable configuration range, it also includes: sending and storing the target configuration information to a backup memory, so that when a configuration data call instruction is received, the target configuration information stored in the backup memory is called.

[0048] Specifically, the backup memory is used to back up and store the target configuration information sent to the external memory for subsequent data calls. The backup memory can be static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), electrically erasable programmable read-only memory (EPROM), etc.

[0049] Continue with Figure 2For example, using EEPROM (Electrically Erasable Programmable read only memory) as a backup memory can ensure that data is not lost after power failure. After the BMC receives the target configuration information, it compares the target configuration information with the initial configuration information and the preset allowable configuration range. When it is determined that the target configuration information is different from the initial configuration information and the target configuration information is within the allowable configuration range, it is determined that the parameter configuration operation of the central processing unit can be performed according to the target configuration information. At this time, the BMC stores the set target configuration information in the EEPROM for backup to avoid loss when the BMC is powered off. On the other hand, it sends the set target configuration information to the CPLD, which is stored in the UFM area by the CPLD for subsequent configuration of the central processing unit.

[0050] The configuration data calling instruction is used to call the target configuration information that meets the configuration requirements. The configuration data calling instruction is used to apply the target configuration information to other tasks besides the central processing unit configuration, such as configuration data comparison, data viewing, etc. Therefore, this embodiment sets the data calling path of the target configuration information and the path for configuring the central processing unit by the target configuration information separately, that is, the data is applied except for the central processing unit configuration through the backup memory, and the data is read and the central processing unit is configured through the external memory, thereby avoiding mutual influence of data action scenarios and improving the implementation stability of the data calling and configuration process.

[0051] After storing the target configuration information in the backup memory and the external memory, this embodiment retrieves the target configuration information from the backup memory if a configuration data call instruction is received, and reads the target configuration information from the external memory if a configuration trigger instruction is received. This achieves the distinction of data application paths, improves the application stability of the target configuration information, and stably implements the configuration process of the central processing unit while improving data storage stability and security.

[0052] In one embodiment of the present application, after configuring the central processing unit based on the target configuration information, the configuration method of the central processing unit also includes: obtaining actual configuration information of the central processing unit and retrieving the target configuration information from the backup memory; when the actual configuration information is inconsistent with the target configuration information, generating a first alarm signal, and alerting the user based on the first alarm signal.

[0053] Specifically, combined Figure 2As shown, the actual configuration information can be obtained through BIOS and sent to the BMC application. After receiving the data sent by BIOS, BMC compares it with the data in EEPROM. If they are consistent, it proves that the setting is successful, and sends a SEL (System Event Log) log for recording. If the setting is unsuccessful, SEL log recording is also performed. At the same time, the system health light will be turned on, and the fan speed will be increased to 80% speed to remind the operation and maintenance and production line setting personnel that the current setting has failed and needs to be intercepted and processed for analysis.

[0054] In the above-mentioned cases where the configuration information is inconsistent, the user is alarmed by lighting the system health light and increasing the fan speed to 80%. In addition to the above-mentioned alarm methods, differentiated alarms can also be made based on the inconsistency between the actual configuration information and the target configuration information. The first alarm signal can be generated accordingly based on the inconsistency between the actual configuration information and the target configuration information, so as to control different alarm methods to remind the user. For example, in the case where the target configuration information includes the target power and the target number of cores, the actual configuration information includes the actual CPU power and the actual number of CPU cores. If the target power is consistent with the actual CPU power and the target number of cores is different from the actual number of CPU cores after information comparison, the first alarm signal generated at this time is a CPU core number configuration failure alarm signal, which can control the first warning light to light up, the first fault code to display, and the fan speed to 80%; if the target number of cores is consistent with the actual number of CPU cores and the target power is different from the actual CPU power after information comparison, the first alarm signal generated at this time is a CPU core number configuration failure alarm signal. U power configuration failure alarm signal can control the second warning light to light up, the second fault code to display, and the fan speed to 80% speed; if the target number of cores and the actual number of CPU cores, and the target power and the actual CPU power are inconsistent after information comparison, the first alarm signal generated at this time is the CPU core number and CPU power configuration failure alarm signal, which can control the first warning light and the second warning light to light up, the third fault code to display, and the fan speed to 80% speed, so as to give differentiated alarms to technicians, so that they can find the configuration fault area in time, which is convenient for subsequent fault inspection and processing.

[0055] In addition, the acquisition of the above-mentioned actual configuration information can be confirmed according to the type of target configuration information. For example, when the target configuration information only includes the target power, only the actual CPU power is obtained for subsequent information comparison and judgment; when the target configuration information only includes the target number of cores, only the actual number of CPU cores is obtained for subsequent information comparison and judgment; when the target configuration information includes the target power and the target number of cores, the actual CPU power and the actual number of CPU cores are obtained, thereby reducing the workload of data collection and data comparison and speeding up work progress.

[0056] Furthermore, when the target configuration information only includes the target power or the target number of cores, the actual CPU power and the actual number of CPU cores can also be acquired synchronously, and the actual signal of the unconfigured information type can be compared with the initial configuration information, and the actual signal of the configured signal type can be compared with the target configuration information to verify the final configuration of the central processing unit, and further generate a corresponding alarm signal based on the comparison result to trigger an alarm reminder based on the alarm signal. For example, when the target configuration information only includes the target power, the actual CPU power is compared with the target power, and the actual number of CPU cores is compared with the initial number of CPU cores. If the two are consistent, the configuration is determined to be successful. If one of them is inconsistent or both are inconsistent, the configuration is considered to have failed, and a first alarm signal is generated to remind the user. For example, when the actual CPU power is consistent with the target power, but the actual number of CPU cores is inconsistent with the initial number of CPU cores, it is considered that the power configuration process has affected the number of CPU cores of the central processing unit, and the first alarm signal generated is a CPU core number misconfiguration alarm. The corresponding warning light, fault code, etc. can be triggered based on the first alarm signal to remind the user. When the actual CPU power is inconsistent with the target power, and the actual number of CPU cores is consistent with the initial number of CPU cores, it is considered that the power configuration has failed, and the first alarm signal generated is a CPU power configuration failure alarm signal. Based on the first alarm signal, the second warning light can be controlled to light up, the second fault code can be displayed, and the fan speed can be increased to 80%.

[0057] This embodiment can generate a first alarm signal when the actual configuration information is inconsistent with the target configuration information, and remind the user of the configuration failure based on the first alarm signal, so that the user can perform subsequent processing in time.

[0058] In one embodiment of the present application, obtaining actual configuration information of a central processing unit includes: obtaining current configuration information of the central processing unit; and when the current configuration information of the central processing unit is different from the initial configuration information, using the current configuration information of the central processing unit as the actual configuration information of the central processing unit.

[0059] Specifically, combined Figure 2 As shown, after the next power-on, the CPLD receives a configuration trigger instruction and reads the preset target configuration information from the UFM area, where the target configuration information includes the target power consumption, and is transmitted to the CPU through the eSPI (Enhanced Serial Peripheral Interface) bus for power consumption setting to take effect.

[0060] Then, the current CPU power consumption of the central processing unit is monitored in real time. When it is determined that the current CPU power consumption is different from the initial CPU power consumption, the power consumption is considered to be effective and the power consumption configuration is completed. Then, the current CPU power consumption obtained is used as the actual CPU power consumption, and the current number of CPU cores obtained is used as the actual number of CPU cores and sent to the BMC for information comparison to determine whether the configuration is successful, thereby improving the configuration evaluation rate.

[0061] When the target configuration information includes target power consumption and target number of cores, whether the configuration is completed can be determined only based on whether the current CPU power consumption or the current number of CPU cores is different from the initial configuration. Alternatively, the current CPU power consumption and the current number of CPU cores can be compared with the initial configuration at the same time to determine whether the configuration is completed, and the actual configuration information can be obtained after the configuration is completed.

[0062] In addition, in order to ensure the configuration progress, the configuration cycle needs to be preset. During the configuration of the central processing unit according to the target configuration information, if the current configuration information obtained within the preset configuration cycle is always consistent with the initial configuration information, the configuration is considered to have failed, and an alarm is issued to the user to avoid wasting time due to the situation where the configuration information of the central processing unit has not changed due to a fault, thereby improving the rationality of configuration control.

[0063] In one embodiment of the present application, after configuring the central processor according to the target configuration information, the method further includes: receiving a reconfiguration instruction of the central processor; and clearing the configuration information in the backup memory and the external memory in response to the reconfiguration instruction.

[0064] Specifically, the reconfiguration instruction is a package setting change instruction received again after the central processor is configured according to the target configuration information. At this time, the EEPROM area of ​​the motherboard and the UFM area of ​​the CPLD are cleared through the BMC according to the reconfiguration instruction, and everything is restored to the unset state for use by other packages. Among them, other packages include target configuration information customized by users.

[0065] Then, after receiving the target configuration information again, the target configuration information received again is compared with the initial configuration information and the preset allowable configuration range, and the target configuration information that meets the requirements is stored in the EEPROM area on the one hand, and in the UFM area of ​​the CPLD on the other hand, so as to execute the configuration process when the configuration trigger instruction is received.

[0066] When receiving a reconfiguration instruction, this embodiment clears the configuration information in the backup memory and the external memory for use by other packages.

[0067] In one embodiment of the present application, the configuration method of the central processor further includes: when the target configuration information is outside a preset allowable configuration range, generating a second alarm signal, and alerting the user based on the second alarm signal.

[0068] That is to say, the preset allowable configuration range is the parameter configuration range supported by the central processor, which can be set based on the hardware structure of the central processor. For example, when the project is shipped, the package setting tool is used to set the CPU power consumption number set by the package customer, that is, the target configuration information, to the BMC. When the user-customized target configuration information is within the preset allowable configuration range, the configuration of the central processor based on the target configuration information is allowed. At this time, the target configuration information is stored in the external memory for subsequent configuration reading applications; when the user-customized target configuration information is outside the preset allowable configuration range, that is, the set target power value is not the power consumption number supported in the preset allowable configuration range, a second alarm signal will be generated to indicate that the package setting has failed.

[0069] The second alarm signal can be distinguished and determined according to the relative relationship between the target configuration information and the preset allowable configuration range. For example, in the case where the target configuration information includes the target power and the target number of cores, if the target power is within the preset allowable configuration range and the target number of cores is outside the preset allowable configuration range, the second alarm signal generated at this time is a target number of cores setting failure alarm, which can trigger the corresponding first package setting failure reminder; if the target number of cores is within the preset allowable configuration range and the target power is outside the preset allowable configuration range, the second alarm signal generated at this time is a target power setting failure alarm, which can trigger the corresponding second package setting failure reminder.

[0070] In addition, the second alarm signal can also make further division reminders based on the numerical difference between the target configuration information and the preset allowable configuration range. For example, when the target power differs greatly from the preset allowable configuration range, the second alarm signal can be at the highest level, such as increasing the flashing frequency of the warning light corresponding to the target power setting failure alarm and adjusting the warning code color to red. Based on the alarm reminder, the user can determine that it is difficult to meet the preset allowable configuration range of the central processor through data adjustment of the target configuration information, and other central processors need to be selected, thereby avoiding subsequent redundant configuration work; when the target power differs little from the preset allowable configuration range, the second alarm signal can be at a lower level, such as controlling the warning light corresponding to the target power setting failure alarm to be always on and adjusting the warning code color to yellow. Based on the alarm reminder, the user can determine that the preset allowable configuration range of the central processor can be met through data fine-tuning of the target configuration information, so as to perform subsequent configuration adjustment work based on the alarm reminder.

[0071] This embodiment can use the second alarm signal to provide differentiated reminders for setting failure situations, so that the user can accurately identify the root cause of the package setting failure according to the alarm type, perform fault processing in a timely manner, and improve the setting progress.

[0072] In one embodiment of the present application, the configuration method of the central processing unit further includes: clearing target configuration information stored in an external memory in response to an initialization instruction; and restoring the central processing unit to initial configuration information based on the cleared external memory.

[0073] Specifically, initialization refers to the process of setting a system, variable, object, or other usable component to its initial state or initial value in computer science and software development.

[0074] Continue with Figure 2 For example, after completing the configuration of the central processing unit according to the target configuration information, if an initialization instruction is received, the target configuration information in the UFM area of ​​the CPLD is cleared according to the initialization instruction, so that the number of cores and / or power consumption of the CPU is no longer customized, and the central processing unit is restored to the default value, that is, the initial configuration information, simplifying the initialization operation steps.

[0075] As a specific embodiment of the present application, the system architecture for executing the configuration method of the central processing unit is as follows: Figure 2 As shown, the configuration method of the central processor is as follows Figure 3 As shown, the following steps are included: S101, after the BIOS is started, the initial configuration information of the CPU and the preset allowed configuration range are sent to the BMC.

[0076] The initial configuration information of the CPU includes the number of CPU cores and power consumption currently running on the CPU, and the preset allowable configuration range of the CPU includes the number of cores and power consumption supported by the current CPU.

[0077] S102, when the project is shipped, the package setting tool is used to set the target configuration information set by the package customer to the BMC. The target configuration information may include target power consumption and / or target number of cores.

[0078] S103, determine whether the target configuration information is different from the initial configuration information. If yes, execute step S104; if no, execute step S116.

[0079] S104, determining whether the target configuration information is within a preset allowable range. If yes, executing step S105; if no, executing step S106.

[0080] S105, the BMC stores the target configuration information in the EEPROM for backup, and sends the target configuration information to the CPLD, which stores the target configuration information in the UFM area. Execute step S107.

[0081] In this step, in order to prevent this key setting from becoming ineffective due to BMC anomalies during operation, the setting information is no longer passed to the BIOS through the BMC each time, but is passed to the BIOS by the CPLD. The values ​​AC and DC in the UFM area and the firmware of the upgraded CPLD will not disappear or change, so the data is stable and will not be lost.

[0082] In addition, BMC provides instructions to set and query the current number of CPU cores and power consumption to EEPROM for backup.

[0083] S106: Generate a second alarm signal, and warn the user based on the second alarm signal, so that the user can check the target configuration information based on the second alarm signal.

[0084] S107, when power is turned on next time, confirm that the configuration trigger instruction is received.

[0085] S108 , in response to the configuration trigger instruction, the CPLD reads target configuration information from the UFM area.

[0086] S109, transmitting the target configuration information to the CPU via the eSPI bus to make the configuration effective.

[0087] Among them, BIOS can synchronize the target configuration information to the setup option Package PL1 Power Limit and execute the Package RAPL limit Lock action to prohibit the configuration modification of the central processing unit under the OS (Operating System).

[0088] S110, obtaining current configuration information of the central processing unit; S111, determine whether the current configuration information is different from the initial configuration information. If yes, execute step S113; if no, execute step S112.

[0089] S112, determine whether the actual configuration time reaches the preset configuration time. If yes, execute step S117; if no, execute step S110.

[0090] S113, using the current configuration information as the actual configuration information of the central processing unit.

[0091] S114, the BMC receives the actual configuration information and retrieves the target configuration information from the backup memory.

[0092] S115, determine whether the actual configuration information is consistent with the target configuration information. If yes, execute step S116; if no, execute step S117.

[0093] In one embodiment, after AC operation, ipmitool (Intelligent Platform Management Interface Tool) is used to check whether BMC records abnormal alarms, including other configuration abnormalities in the package and RPAL (Robotic Process Automation) setting abnormal alarms. If the check passes, the process ends, otherwise check whether the configuration information is normal.

[0094] S116, the BMC determines that the central processor is configured successfully, and sends a SEL log for recording.

[0095] In addition, after successful configuration, when receiving the initialization command, it supports clearing the CPLD UFM area function, so that the number of CPU cores and power consumption are no longer customized and restored to the default values.

[0096] S117: The BMC determines that the CPU configuration has failed and records the failure in the SEL log. At the same time, it turns on the system health indicator and increases the fan speed to 80% to remind the user.

[0097] That is to say, after the BIOS is started, the current number of CPU cores and power consumption will be sent to the BMC, which will compare and confirm them. If they are inconsistent with the settings, an alarm will be issued and the fan speed will be increased to inform the operation and maintenance personnel that there is a setting problem.

[0098] Therefore, this embodiment can set the number of CPU cores and power consumption without changing the CPU entity when the project is shipped, so that there is no need to customize and replace the CPU again when shipping and applying, and it is convenient for modification and maintenance, which has objective economic significance.

[0099] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method.
