Technical Field

[0002] The embodiments of the present application relate to the field of server technology, and in particular to a method for adjusting the non-core frequency of a processor and a computing device. Background Art

[0003] As the demand for processor systems continues to grow, processors require a better balance between performance and power consumption to meet the needs of running various applications. In addition to the core area, the processor system also includes a non-core area.

[0004] Currently, the processor can run at a pre-set non-core frequency, which leads to limitations in the processor's non-core frequency. There is a problem that the pre-set processor's non-core frequency cannot meet the server's operating requirements, resulting in the server's operating performance not meeting expectations.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a method for adjusting the non-core frequency of a processor and a computing device, which improve the flexibility of adjusting the non-core frequency of the processor, thereby improving the performance of the processor in running and processing different services.

[0007] In a first aspect, the present application provides a method for adjusting the non-core frequency of a processor, the method comprising: obtaining parameters of status information; the parameters of the status information are used to indicate the working state of the processor when the non-core area in the processor operates at a first non-core frequency; determining a second non-core frequency of the processor corresponding to the parameters of the status information based on the parameters of the status information; and adjusting the non-core frequency of the processor from the first non-core frequency to the second non-core frequency.

[0008] It is understandable that parameters of status information indicating the operating state of the processor when the non-core area in the processor is operating at a first non-core frequency are obtained, and based on the obtained parameters of the status information, a second non-core frequency of the processor corresponding to the parameters of the status information is determined, thereby adjusting the non-core frequency of the processor from the first non-core frequency to the second non-core frequency. Since the non-core frequency of the processor can be adjusted according to the non-core frequency corresponding to the parameters of the status information, the non-core frequency corresponding to the parameters of the status information can be adjusted according to different business needs, thereby meeting the balance between performance and power consumption of the processor in accordance with different business needs, thereby improving the effectiveness of the processor in processing business operations.

[0009] In one possible implementation, determining the second non-core frequency of the processor corresponding to the parameters of the status information based on the parameters of the status information includes: obtaining configuration information; the configuration information includes the non-core frequencies corresponding to each threshold range to which the parameters of the status information configured by the user through the BIOS menu belong; determining the non-core frequency corresponding to the target threshold range as the second non-core frequency of the processor; the target threshold range is the threshold range to which the parameters of the status information belong.

[0010] It can be understood that by the user entering configuration information in the BIOS configuration menu, the correspondence between the various parameters of the status information and the non-core frequency is determined, so that the user can configure different correspondences according to different business needs, thereby determining the second non-core frequency of the processor based on the parameters of the status information to meet business needs and improve business operation results.

[0011] In one possible implementation, determining the second non-core frequency of the processor corresponding to the state information parameters according to the state information parameters includes: inputting the state information parameters into a preset algorithm; and outputting the second non-core frequency of the processor through the preset algorithm.

[0012] It is understandable that by presetting the algorithm to determine the second non-core frequency corresponding to the parameters of the state information, the second non-core frequency of the processor determined according to the parameters of the state information can meet business needs and improve business operation effects.

[0013] In a possible implementation, obtaining the parameters of the status information includes: obtaining the parameters of the status information from a baseboard management controller (BMC); wherein the parameters of the status information are calculated by an interrupt processing function when the BMC periodically triggers an interrupt to enter a system management mode (SMM).

[0014] It is understandable that by setting a timer in the BMC, an interrupt to the operating system is triggered regularly, so that the operating system enters the SMM mode, and the parameters of the status information are calculated or obtained through the interrupt processing function.

[0015] In one possible implementation, adjusting the non-core frequency of the processor from a first non-core frequency to a second non-core frequency includes: if a difference between the first non-core frequency and the second non-core frequency is greater than a specified threshold, adjusting the non-core frequency of the processor from the first non-core frequency to the second non-core frequency.

[0016] It is understood that after determining the second non-core frequency, the second non-core frequency can be compared with the current first non-core frequency. If the difference between the two is less than or equal to a specified threshold, the processor's non-core frequency can be adjusted without being controlled. Since the frequency adjustment range is small, the impact on the processor's performance and power consumption before and after the adjustment is small. If the difference between the two is greater than the specified threshold, the processor's non-core frequency can be adjusted. This ensures that the adjusted second non-core frequency of the processor meets business needs and improves business performance.

[0017] In one possible implementation, determining a second non-core frequency of a processor corresponding to the parameters of the status information based on the parameters of the status information includes: determining a value range of the non-core frequency of the processor corresponding to the parameters of the status information based on the parameters of the status information; determining the second non-core frequency of the processor; and the second non-core frequency being within the value range.

[0018] It can be understood that the value range of the frequency to which the non-core frequency supports adjustment can be determined through the parameters of the status information, and the second non-core frequency can be determined from the value range, so that after determining the value range of an adjusted non-core frequency, the second non-core frequency can be determined more accurately therefrom, so that the business can achieve better operation.

[0019] In a possible implementation, if parameters of at least two pieces of state information are obtained, the second non-core frequency is within the intersection of value ranges corresponding to the at least two pieces of state information.

[0020] It can be understood that when determining the second non-core frequency based on the parameters of multiple state information, the value range of the non-core frequency corresponding to each parameter can be determined for each parameter of each state information respectively, and the intersection of the value ranges corresponding to the parameters of each state information is taken to obtain the second non-core frequency that meets the value range corresponding to each state information.

[0021] In one possible implementation, adjusting the non-core frequency of the processor from a first non-core frequency to a second non-core frequency includes: adjusting the non-core frequency of the processor from the first non-core frequency to the second non-core frequency through a non-core frequency scaling UFS function.

[0022] It can be understood that through the UFS function, the non-core frequency of the processor can be adjusted from the first non-core frequency to the second non-core frequency, so that the non-core frequency of the processor can be adjusted to the second non-core frequency that meets business needs, thereby improving the operation effect of the business.

[0023] In one possible implementation, the status information includes at least one of processor utilization, operating system load, and processor temperature; wherein, the processor utilization is positively correlated with the non-core frequency of the processor; the operating system load is positively correlated with the non-core frequency of the processor; and the processor temperature is negatively correlated with the non-core frequency of the processor.

[0024] It can be understood that the non-core frequency corresponding to the current parameters can be determined based on one or more of the processor utilization, operating system load and processor temperature. The numerical value of the processor's non-core frequency can be adjusted according to the relationship between one or more of the processor utilization, operating system load and processor temperature and the non-core frequency, so as to increase the non-core frequency or decrease the non-core frequency, thereby meeting the balance between the performance and power consumption of the processor according to different business needs, thereby improving the effectiveness of the processor in running and processing business.

[0025] In a second aspect, the present application provides a non-core frequency adjustment device for a processor, which is used to execute any one of the non-core frequency adjustment methods for a processor provided in the first aspect.

[0026] In a possible implementation, the present application may divide the non-core frequency adjustment device of the processor into functional modules according to the method provided in the first aspect above. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. Exemplarily, the present application may divide the non-core frequency adjustment device of the processor into an acquisition module, a processing module, and an adjustment module, etc. according to the function. The description of the possible technical solutions and beneficial effects executed by each of the functional modules divided above can refer to the technical solutions provided by the first aspect above or its corresponding possible implementation, and will not be repeated here.

[0027] In a third aspect, an embodiment of the present application provides a computing device, which includes a processor and a memory, wherein the processor is coupled to the memory; the memory is used to store computer instructions, which are loaded and executed by the processor to enable the computing device to implement the non-core frequency adjustment method of the processor as described in the above aspects.

[0028] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, which stores at least one computer program instruction, and the computer program instruction is loaded and executed by a processor to implement the non-core frequency adjustment method of the processor as described in the above aspects.

[0029] In a fifth aspect, embodiments of the present application provide a computer program product, comprising computer instructions stored in a computer-readable storage medium. A processor of a computing device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computing device to perform the method for adjusting the non-core frequency of a processor provided in various optional implementations of the first aspect.

[0038] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0039] In this document, "plurality" refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0040] Furthermore, in the description of this application, unless otherwise specified, "plurality" means two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or plural.

[0041] In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit differences. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0042] First, the application scenarios of the embodiments of the present application are exemplarily introduced.

[0043] In some application scenarios, to balance processor performance and power consumption so that the processor can meet the needs of running various applications, it is necessary to adjust the CPU frequency. The CPU frequency includes the core frequency and the non-core frequency. The higher the CPU frequency, the greater the processor power consumption. Conversely, the lower the CPU frequency, the lower the processor power consumption. Different applications require different processor performance and power consumption. For example, if an application requires a higher-performance processor, the non-core frequency of the processor needs to be increased. If an application needs to minimize processor power consumption while maintaining basic performance, the non-core frequency of the processor needs to be lowered.

[0044] Some scenarios demand high performance and require higher non-core frequencies. However, since it's unclear what value the non-core frequency should be adjusted to to guarantee the required performance, the non-core frequency may be lowered to the lowest possible frequency to ensure the required performance, failing to meet performance requirements. In some scenarios, the frequency can be lowered to save power, but since it's unclear what value the non-core frequency should be adjusted to to guarantee the required power savings, the non-core frequency may be raised to the highest possible frequency to ensure the required power savings, failing to meet power requirements.

[0045] The following embodiment of the present application provides a method for adjusting the non-core frequency of a processor, by obtaining parameters of status information used to indicate the current working status of a processor in the processor, determining the non-core frequency corresponding to the parameter based on the parameters of the status information, and thereby adjusting the non-core frequency of the processor. Since the non-core frequency of the processor can be adjusted according to the non-core frequency corresponding to the parameters of the status information, the non-core frequency corresponding to the parameters of the status information is adjusted according to different business needs, thereby meeting the balance between performance and power consumption of the processor according to different business needs, thereby improving the effectiveness of the processor in running and processing business.

[0046] Next, the system architecture of the embodiment of the present application is exemplarily introduced.

[0047] Figure 1 shows a schematic diagram of a computing device provided by an embodiment of the present application. In terms of hardware, the computing device 100 includes a processor (central processing unit, CPU) 101, a basic input and output system (basic input and output system, BIOS) chip 102, and a baseboard management controller (Baseboard Management Controller, BMC) 103.

[0048] The CPU 101 may include a core area and a non-core area. The core area may be used to perform main operations and processing on data, and the non-core area may be an area of ​​the CPU 101 other than the core area.

[0049] For example, the core area may include the kernel, and the non-core area may include the memory manager, cache, and peripheral component interconnect express (PCIe) interface.

[0050] The BIOS chip 102 may be a read-only memory (ROM) chip on the motherboard of the computing device 100. The BIOS may be a set of programs embedded in the BIOS chip 102. By running the BIOS, the CPU 101 can implement basic input and output programs for the computing device, self-test programs after power-on, and operating system self-start programs. The BIOS provides the most basic and direct hardware configuration and control functions for the computing device.

[0051] BMC103 can be an independent chip integrated on the motherboard of the computing device 100. The BMC can run a small operating system independent of the server's operating system. The BMC103 can be used to manage the core functions of the computing device 100, such as the hardware status, operating system, health status, and power consumption management.

[0052] In terms of software, the computing device 100 can run an operating system (OS) through the core of the CPU 101. The OS can run application programs to process different services.

[0053] Optionally, the computing device 100 may be a server or a computer device.

[0054] The core area and non-core area of ​​the CPU 101 each have their own operating frequencies. The operating frequency of the core area can be the core frequency, and the operating frequency of the non-core area can be the non-core frequency. Because the processor has different requirements when running different applications to process different services.

[0055] For example, when some applications are running, the processor needs to have higher performance, that is, the processor needs to increase the non-core frequency; and when some applications are running, the processor needs to have lower power consumption, that is, the processor needs to lower the non-core frequency.

[0056] In one possible implementation, the BIOS obtains parameters of status information, which can be used to indicate the working status of the processor when the non-core area of ​​the processor runs at a first non-core frequency. The first non-core frequency is the working frequency of the non-core area in the processor counted by the BIOS.

[0057] In one possible implementation, the BIOS includes a preset algorithm that can determine the correspondence between the parameters of the status information and the non-core frequency according to business needs; that is, the BIOS determines the corresponding second non-core frequency through the preset algorithm based on the parameters of the received status information, and the BIOS can adjust the non-core frequency of the processor when it is running to the second non-core frequency.

[0058] Alternatively, the user can configure the non-core frequencies corresponding to each threshold range to which the parameters of the status information belong through the BIOS menu. That is, the BIOS can determine the second non-core frequency corresponding to the parameters of the status information through configuration information based on the parameters of the received status information, and the BIOS can adjust the non-core frequency of the processor when it is running to the second non-core frequency.

[0059] The BMC 103 may include a timer. The BMC 103 may trigger a system process interrupt at regular intervals by triggering the timer, causing the system to enter a system management mode (SMM). The parameters of the current state information may be calculated or obtained in the SMM interrupt processing function.

[0060] SMM is a CPU execution mode. It uses the system management interrupt (SMI) to control the current operating process. Since the SMI interrupt is the highest priority interrupt and cannot be blocked, all other CPU operations are blocked in SMM. The interrupt handler function can be used to calculate or retrieve parameters related to the current state.

[0061] It should be noted that the system architecture and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0062] For ease of understanding, the non-core frequency adjustment method of the processor provided in the present application is exemplarily introduced below with reference to the accompanying drawings. The non-core frequency adjustment method of the processor is applicable to the computing device shown in FIG1 .

[0063] FIG2 is a flow chart showing a method for adjusting the non-core frequency of a processor provided by an exemplary embodiment of the present application. The method for adjusting the non-core frequency of a processor includes the following steps:

[0064] S101, obtaining parameters of status information.

[0065] In an embodiment of the present application, parameters of processor status information are obtained, and the parameters of the status information can be used to indicate the working state of the processor when a non-core area in the processor operates at a first non-core frequency.

[0066] The processor may include a core area and a non-core area.

[0067] For example, the core area may include the core, and the non-core area may include the memory controller, cache, and PCIe interface.

[0068] In one possible implementation, the BIOS may obtain parameters of the status information from the BMC. The parameters of the status information may be calculated or obtained by an interrupt processing function when the BMC triggers an interrupt regularly and enters SMM, and when the operating system enters SMM.

[0069] The BMC can include a timer. When the timer triggers, it can initiate an SMI to the operating system, interrupting the OS process and causing the OS to enter SMM. The BMC then calculates or obtains the parameters of the current state information through the interrupt processing function. After obtaining the parameters of the current state information, the BMC can send the parameters of the current state information to the BIOS.

[0070] That is, the first non-core frequency may be the operating frequency of the non-core region of the CPU when the timer is triggered to issue an SMI to the operating system.

[0071] Exemplarily, the status information may include at least one of CPU utilization, operating system load, and processor temperature, wherein processor utilization is positively correlated with the non-core frequency of the processor; operating system load is positively correlated with the non-core frequency of the processor; and processor temperature is negatively correlated with the non-core frequency of the processor.

[0072] For example, if the status information includes CPU utilization, after the BMC triggers the timer, the BIOS can obtain the value of the CPU utilization, and the CPU utilization can be obtained by the BMC through the interrupt processing function; if the status information includes the operating system load, the BIOS can obtain the operating system load, and the operating system load can be obtained from the operating system by the BMC through the interrupt processing function; if the status information includes the processor temperature, the BIOS can obtain the processor temperature, and the processor temperature can be obtained by the BMC through the interrupt processing function query.

[0073] In order to balance processor performance and power consumption, the non-core frequency of the processor can be adjusted to meet the needs of different applications.

[0074] For example, if the status information includes operating system load, then when the operating system load is determined to be light, the processor's non-core frequency can be adjusted down to conserve energy, thereby improving the operating efficiency and stability of the entire operating system. If the operating system load is determined to be heavy, the processor's non-core frequency can be adjusted up to improve performance. If the status information includes processor utilization, then when the processor utilization is less than a specified threshold, the processor's non-core frequency can be adjusted down to conserve power while ensuring processor efficiency. If the processor utilization is determined to be greater than or equal to a specified threshold, the processor's non-core frequency can be adjusted up to improve performance. If the status information includes processor temperature, then when the processor temperature is less than a specified temperature threshold, the processor's non-core frequency can be adjusted up to improve performance while ensuring the processor does not overheat. If the processor temperature is determined to be greater than or equal to a specified temperature threshold, the processor's non-core frequency can be adjusted down to lower the processor temperature and reduce the risk of processor failure due to overheating.

[0075] In a possible implementation, the BIOS may obtain parameters of one or more status information.

[0076] For example, the BMC may obtain parameters of one or more types of status information and send the obtained parameters of each type of status information to the BIOS. The BIOS subsequently adjusts the non-core frequency of the CPU according to the parameters of each type of status information.

[0077] S102 : Determine, based on the parameters of the state information, a second non-core frequency of the processor corresponding to the parameters of the state information.

[0078] In an embodiment of the present application, after the BIOS obtains the parameters of the status information, the BIOS may determine the second non-core frequency of the processor corresponding to the parameters of the status information according to the parameters of the status information.

[0079] The second non-core frequency may be the operating frequency of the non-core region of the processor adjusted according to the parameters of the state information. The second non-core frequency may be the same as or different from the first non-core frequency.

[0080] In order to determine the influence of the parameters of the state information on the non-core frequency, it can be achieved by presetting the corresponding relationship or by presetting the algorithm, as shown below.

[0081] In a possible implementation, the BIOS may obtain configuration information, and then determine the non-core frequency corresponding to the target threshold range as the second non-core frequency of the processor.

[0082] The configuration information may include the non-core frequencies corresponding to the respective threshold ranges to which the state information parameters configured by the user through the BIOS menu belong. The target threshold range may be the threshold range to which the state information parameters belong.

[0083] That is to say, the BIOS configuration menu is displayed to the user in advance, and by allowing the user to input the correspondence between the parameters of the status information and the non-core frequency in the BIOS configuration menu, the BIOS can determine the correspondence between the parameters of the status information and the non-core frequency, so that the BIOS can determine the non-core frequency corresponding to the parameters of the acquired status information according to the correspondence, and the non-core frequency is the second non-core frequency.

[0084] For example, Figure 3 is a diagram of a BIOS configuration menu display interface according to an embodiment of the present application. As shown in Figure 3, the BIOS configuration menu 20 displayed to the user may include a status information selection area 21 and a correspondence input area 22. The user can select status information displayed in the status information selection area, including CPU utilization, operating system load, and processor temperature, to determine the status information for which a correspondence needs to be configured. For example, if the status information selected for a correspondence is CPU utilization, the user can configure the adjustable range of the non-core frequency corresponding to each range of CPU utilization in the correspondence input area 22. In other words, the user can configure the non-core frequency range corresponding to the CPU utilization range of 0 to 20%. Similarly, the user can sequentially configure the non-core frequency range corresponding to each range of CPU utilization. After the user completes the configuration of the correspondence between CPU utilization and non-core frequency, the user can trigger a confirmation control to have the BIOS acquire the user-configured correspondence. The user can then select other status information for which a correspondence has not been configured in the status information selection area 21 and configure the correspondence for each of the other status information in the correspondence input area 22.

[0085] In another possible implementation, the parameters of the state information are input into a preset algorithm, and the second non-core frequency of the processor is output through the preset algorithm.

[0086] The preset algorithm may be an algorithm for finding an optimal solution, or a pre-trained neural network model algorithm.

[0087] That is to say, if the preset algorithm is an algorithm for finding the optimal solution, it can be that when the computing device runs according to the parameters of the obtained status information, while ensuring the CPU performance and satisfying that the CPU power consumption is less than a specified threshold, the optimal solution of the non-core frequency is calculated, and the optimal solution is determined as the second non-core frequency corresponding to the parameters of the obtained status information.

[0088] In one possible implementation, based on the parameters of the state information, a value range of a non-core frequency of the processor corresponding to the parameters of the state information is determined; a second non-core frequency of the processor is determined; and the second non-core frequency is within the value range.

[0089] In addition, the BIOS may determine the second non-core frequency according to a parameter of a type of status information, or may determine the second non-core frequency according to a combination of parameters of multiple types of status information.

[0090] In a possible implementation, if parameters of at least two pieces of state information are obtained, the second non-core frequency is within the intersection of value ranges corresponding to the at least two pieces of state information.

[0091] That is to say, if the BIOS obtains the parameters of multiple status information, the BIOS can respectively determine the value range of the non-core frequency corresponding to the parameters of each status information, and use the intersection of each value range as the value range of the second non-core frequency, thereby determining the second non-core frequency.

[0092] For example, if the BIOS obtains that the CPU utilization is x%, the BIOS can determine that the lower limit of the value range of the non-core frequency corresponding to the CPU utilization of x% is a, and the upper limit is b. If the BIOS also obtains that the operating system load is y, the BIOS can determine that the lower limit of the value range of the non-core frequency corresponding to the operating system load y is c, and the upper limit is d. If the BIOS also obtains that the processor temperature is z, the BIOS can determine that the lower limit of the value range of the non-core frequency corresponding to the processor temperature z is m, and the upper limit is n. The value ranges of the non-core frequencies corresponding to the three types of status information are intersected. Since m is less than a, a is less than c, c is less than b, b is less than n, and n is less than d, it can be determined that the lower limit of the value range to which the second non-core frequency belongs is c, and the upper limit is b.

[0093] S103: Adjust the non-core frequency of the processor from the first non-core frequency to the second non-core frequency.

[0094] In the embodiment of the present application, after determining the second non-core frequency, the BIOS can control and adjust the non-core frequency of the processor.

[0095] In a possible implementation, the BIOS may modify the upper and lower limits of the non-core frequency value range so that the processor subsequently adjusts the non-core frequency within the adjusted value range.

[0096] In addition, if the difference between the second non-core frequency determined based on the parameters of the status information and the first non-core frequency is small, this will result in the effect of controlling the CPU to adjust the non-core frequency being not obvious. In order to reduce unnecessary instruction operations, the current first non-core frequency can be maintained to continue running the CPU when the difference is less than the specified threshold.

[0097] That is, if the difference between the first non-core frequency and the second non-core frequency is greater than a specified threshold, the non-core frequency of the processor is adjusted from the first non-core frequency to the second non-core frequency.

[0098] In another possible implementation, after obtaining the second non-core frequency, the BIOS needs to determine whether the second non-core frequency is the same as the first non-core frequency. If the second non-core frequency is determined to be the same as the first non-core frequency, there is no need to adjust the processor's non-core frequency, and the processor waits for the next time the timer is triggered before obtaining the second non-core frequency. If the second non-core frequency is determined to be different from the first non-core frequency, the processor's non-core frequency can be subsequently adjusted from the first non-core frequency to the second non-core frequency.

[0099] In summary, the server obtains, through the BIOS, parameters of status information indicating the working status of the processor when the non-core area in the processor is running at the first non-core frequency, and based on the parameters of the obtained status information, it can determine the second non-core frequency of the processor corresponding to the parameters of the status information, thereby adjusting the non-core frequency of the processor from the first non-core frequency to the second non-core frequency. Since the non-core frequency of the processor can be adjusted according to the non-core frequency corresponding to the parameters of the status information, the non-core frequency corresponding to the parameters of the status information can be adjusted according to different business needs, thereby meeting the balance between performance and power consumption of the processor according to different business needs, thereby improving the effectiveness of the processor in running and processing business.

[0100] For example, FIG4 is a flow chart of adjusting the non-core frequency of a processor involved in an embodiment of the present application. As shown in FIG4 , the non-core frequency corresponding to different parameters of the status information is obtained (S21), wherein, in one possible case, if the status information is the CPU utilization, the non-core frequency corresponding to the different CPU utilizations input by the user can be obtained, or, in another possible case, if the status information is the CPU utilization or OS load, the non-core frequency that should be set when the different CPU utilizations or OS loads are calculated by a preset algorithm. Then, when the operating system is running, the BMC can be triggered by a timer, pull the GPIO pin, trigger the OS interrupt, and make the OS enter SMM. The BMC can obtain the parameters of the current status information (S22) through the interrupt processing function, such as the current CPU utilization or the current OS load, and then determine whether the current non-core frequency corresponds to the parameters of the current status information (S23), that is, whether the current non-core frequency corresponds to the current CPU utilization or the current OS load. If it is determined that the current non-core frequency does not correspond to the parameters of the current state information, the non-core frequency of the processor can be adjusted, and the non-core frequency can be adjusted to the non-core frequency corresponding to the parameters of the current state information (S24). Then, it is determined whether the OS has stopped running (S25). If it is determined that the OS has stopped running, the process of adjusting the non-core frequency of the processor is terminated. If it is determined that the OS has not stopped running, the above process is continued to be executed from S22. In addition, if after executing S23, it is determined that the current non-core frequency corresponds to the parameters of the current state information, the above steps are directly executed from S25.

[0101] In a possible implementation, the uncore frequency of the processor is adjusted from a first uncore frequency to a second uncore frequency through an uncore frequency scaling (UFS) function.

[0102] UFS is a feature in the processor that provides frequency scaling control for uncore areas. By controlling the frequency scaling of these areas, the balance between overall processor performance and power consumption can be adjusted.

[0103] That is to say, by obtaining the parameters of the status information indicating the current working status of the processor in the processor, the non-core frequency corresponding to the parameter is determined according to the parameters of the status information, thereby adjusting the non-core frequency of the processor. Since the non-core frequency of the processor can be adjusted according to the non-core frequency corresponding to the parameters of the status information, the non-core frequency corresponding to the parameters of the status information is adjusted according to different business needs, thereby meeting the balance between the performance and power consumption of the processor according to different business needs, thereby improving the effect of the processor in running and processing business.

[0104] For example, FIG5 is a flowchart of a processor adjusting non-core frequency involved in an embodiment of the present application. As shown in FIG5, the BIOS can obtain the upper and lower limit values ​​of the non-core frequency corresponding to different parameters of the status information input by the user through the BIOS configuration menu, or the BIOS can obtain the upper and lower limit values ​​of the non-core frequency corresponding to different parameters of the status information through a preset algorithm (S31). After the operating system is started, the timer in the BMC can start a timer trigger, and the BMC timer triggers the SMI (S32). After the operating system enters SMM, when the operating system is in SMM, the current parameters of the status information are calculated or obtained through the interrupt processing function. The BMC sends the obtained current parameters of the status information to the BIOS, so that the BIOS obtains the current parameters of the status information (S33). The BIOS can select and adjust the non-core frequency or the value range of the non-core frequency to the predetermined corresponding second non-core frequency and value range based on the parameters of the obtained status information (S34). Determine whether the operating system has stopped running (S35). If it is determined that the operating system has stopped running, there is no need to adjust the non-core frequency, that is, the process of adjusting the non-core frequency can be ended; if it is determined that the operating system has not stopped running, continue to wait for S32 and subsequent steps to be executed.

[0105] In summary, by dynamically adjusting the non-core frequency of the processor outside the core, such as the memory controller and cache, the performance and power requirements of different applications can be met. The operating system or application can dynamically adjust the processor's non-core frequency based on the current load status and performance requirements. The BIOS can obtain real-time information such as CPU utilization, processor temperature, or operating system load, and flexibly adjust the processor's non-core frequency. This can improve the response speed to the processor's non-core frequency adjustment and flexibly optimize the processor's energy consumption and performance. In addition, because the status information parameters can include the processor's temperature, the processor's non-core frequency can be lowered according to the processor temperature, thereby reducing the heat and noise generated by excessive processor frequency. This can meet the needs of low-noise, low-power, or temperature-sensitive environments. Since the processor's non-core frequency can be flexibly adjusted on demand, the risk of processor overuse can be reduced, thereby extending the processor's service life to a certain extent.
