Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The development of a domestic CPU (processor) is more and more emphasized in China, and an ARM platform-based autonomous research and development processor has advanced to the leading level of the industry and is widely applied to various industries such as communication, Internet and the like at present. However, due to the limitation of the AMR platform, the public version design is slightly simpler than that of the X86 platform, and the monitoring of functions such as CPU temperature, frequency modulation and the like is not managed by an ME (Management Engine) like the X86 platform, and the power consumption control function of the ARM platform is also limited, so that the invention provides a power consumption control method, system, device and storage medium for the ARM platform, which first obtains the real-time overall power consumption value of the server and compares the real-time overall power consumption value with the preset power consumption reference value of the server; when the real-time complete machine power consumption value deviates from the preset power consumption reference value range, the baseboard management controller issues an intelligent platform management interface command to an operating system of the server through a low pin number interface; and acquiring an operating system command corresponding to the intelligent platform management interface command from a command mapping script, acquiring a corresponding power consumption control strategy table according to the operating system command, and slightly executing power consumption control operation according to the power consumption control strategy table so as to realize the power consumption control function of the ARM platform.

The first embodiment is as follows:

referring to fig. 1 to 2, a power consumption control method of an ARM platform server according to the present embodiment is shown, where fig. 1 is a first method flowchart of the power consumption control method of the ARM platform server according to the present invention; fig. 2 is a second method flowchart of the ARM platform server power consumption control method of the present invention.

The power consumption control method of the ARM platform server comprises the following steps:

in order to control the power consumption, a comparison mechanism between a real-time complete machine power consumption value and a preset reference value is established, a power consumption feedback mechanism is established by adjusting the frequency or the number of processor cores of a processor which normally works according to the comparison mechanism, and the power consumption control function is realized through the power consumption feedback mechanism. Therefore, a real-time complete machine power consumption value of the server is obtained firstly, and the method for obtaining the real-time complete machine power consumption value is as follows: the baseboard Management controller obtains a real-time Power consumption value of the whole machine from a Power supply of the server through a Power Management Bus (PMbus). After the real-time complete machine power consumption value is obtained, the real-time complete machine power consumption value can be compared with the preset power consumption reference value to obtain the relation between the real-time complete machine power consumption value and the preset power consumption reference value, and a power consumption feedback regulation mechanism of an ARM platform is conveniently established.

under normal conditions, the real-time power consumption value of the whole machine is within the range of the preset power consumption reference value, and the server does not need to control the power consumption. In order to reasonably use resources to the maximum extent and reduce the waste of resources, a power consumption feedback mechanism needs to be established, when the real-time complete machine power consumption value deviates from a preset power consumption reference value, that is, the real-time complete machine power consumption value is not within the range of the preset power consumption reference value (including two cases that the real-time complete machine power consumption value is greater than the preset power consumption reference value and the real-time complete machine power consumption value is less than the preset power consumption reference value, the reference value can be selected to be a numerical value range or a specific numerical value), at this moment, the real-time complete machine power consumption value needs to be adjusted through the power consumption feedback mechanism, so that the real-time complete machine power consumption value is kept within the normal range of the preset power consumption reference value. For the ARM Platform, there is no power consumption control managed by ME similar to the x86 Platform, so the present invention uses the Baseboard Management Controller (BMC) to issue an Intelligent Platform Management Interface command (IPMI command) to the Operating System (OS) of the server through the Low pin count Interface (LPC, Low pin count Bus) to implement communication with the Operating System, and further opens the kernel Interface of the processor through the Operating System to perform frequency adjustment or kernel number adjustment (to turn on or turn off the processor kernel).

after issuing an intelligent platform management interface command to an operating system of a server through a low pin count interface, the baseboard management controller triggers an interrupt, so that the operating system executes an interrupt processing program, namely, executes a corresponding operating system command. The command mapping script stores the mapping relation between the intelligent platform management interface command and the operating system command, the operating system command corresponding to the intelligent platform management interface command is obtained through the command mapping script, then the operating system executes the operating system command corresponding to the intelligent platform management interface command and issued by the substrate management controller, and the operating system command can trigger related frequency adjustment or kernel number adjustment.

After the operating system command corresponding to the intelligent platform management interface command is obtained from the command mapping script, the operating system command needs to be executed to control power consumption. After the operating system command is acquired, the power consumption control strategy table corresponding to the operating system command can be acquired according to the operating system command, and the power consumption control strategy table stores the parameters for frequency adjustment and the parameters for kernel number adjustment, so that the corresponding power consumption control can be performed by executing the operating system command according to the power consumption control strategy table, namely, the adjustment of the processor frequency and/or the adjustment of the kernel number. The power consumption control method can be set to be on or off in the baseboard management controller, and the power consumption control method is allowed to be executed when the power consumption control method is on.

A preset power consumption reference value can be set on a BMC (baseboard management controller) WEB, a user sets a corresponding preset power consumption reference value according to the actual configuration of a server, and then the preset power consumption reference value can be acquired from the baseboard management controller when power consumption control is carried out, so that the real-time complete machine power consumption value and the preset power consumption reference value can be compared conveniently.

after the baseboard management controller issues the intelligent platform management interface command to the operating system of the server through the low pin number interface, the operating system command corresponding to the intelligent platform management interface command can be obtained from the command mapping script, and the mapping relation between the intelligent platform management interface command and the operating system command is stored in the mapping script file, so that before the operating system command corresponding to the intelligent platform management interface command is obtained from the command mapping script, the mapping relation between the intelligent platform management interface command and the operating system command needs to be established in advance and stored in the command mapping script.

Wherein the intelligent platform management interface command comprises:

and the fourth intelligent platform management interface command, wherein the corresponding operating system command is a command for setting the kernel state of the processor.

The Userspace function implements frequency setting (allows the root-authorized user to set the cpu frequency to the frequency desired by the user through the "scaling _ scheduled field of sysfs). Therefore, the substrate management controller also correspondingly sets the intelligent platform management interface commands corresponding to the functions realized by the operating system commands in the commands issued to the operating system of the server through the low pin count interface, and the mapping relation is established in a one-to-one correspondence manner. After the operating system receives the first intelligent platform management interface command, the operating system executes an operating system command for reading the frequency of the processor; after the operating system receives the second intelligent platform management interface command, the operating system can execute an operating system command for setting the processor frequency; after the operating system receives the third intelligent platform management interface command, the operating system can execute an operating system command for reading the kernel number of the processor; after the operating system receives the fourth intelligent platform management interface command, the operating system executes an operating system command for setting the kernel state of the processor. Further, setting the state of the core processor, i.e. turning on or off the processor core, before setting the state of the processor core, a relationship between the operating system and the processor core is to be established, i.e. numbering the processor core, e.g. 64 cores of a processor, numbering the cores, CPU 0core 1, CPU 0core 2, … …, CPU 0core 62, CPU 0core 63, and closing the relevant instructions of the processor core, e.g. closing the CPU 0core 12 core, commanding echo 0> dir (path) CPU 0_ core 12), where 0 denotes the processor core is closed and 1 denotes the processor core is opened.

establishing a power consumption control strategy table;

In order to adjust the frequency or the number of cores according to a set power consumption control strategy, the power consumption control strategy is preset, so that a power consumption control strategy table is preset before a power consumption control strategy table corresponding to an operating system command is acquired, so that power consumption control is performed according to strategy parameters in the power consumption control strategy table. The power consumption control comprises two control modes, one mode is to realize the power consumption control by adjusting the frequency of the processor, and when the real-time power consumption value of the whole machine is overlarge, the frequency of the processor is reduced; when the real-time power consumption value of the whole machine is too small, the frequency of the processor is improved; the other is to adjust the number of the processor cores, namely, to open or close the corresponding number of the processor cores, and to close the corresponding number of the processor cores when the real-time power consumption value of the whole machine is overlarge; and when the power consumption value of the real-time complete machine is too small, starting the corresponding number of processor cores. Therefore, the corresponding adjusting parameters comprise a frequency adjusting parameter and a kernel adjusting parameter, and the two adjusting parameters are used for controlling the power consumption according to the set change strategy. The user can update the frequency adjusting parameters in the frequency control strategy table and the kernel adjusting parameters in the kernel control strategy table according to actual requirements so as to meet the power consumption control requirements of different servers.

The power consumption control strategy table comprises a frequency control strategy table and a kernel control strategy table, generally, when the flow of the power consumption control strategy is executed, firstly, a power consumption control mode for adjusting the frequency is carried out, then, the power consumption control mode for adjusting the kernel is carried out, if the power consumption control effect is not ideal, then, the power consumption control mode for adjusting the frequency is executed again, namely, the two power consumption control modes are executed alternately, and then, the operating system command is executed alternately according to the frequency control strategy table and the kernel control strategy table. In the process of adjusting the frequency, if the frequency is directly reduced to a very low level for the purpose of power consumption control effect, the performance of the processor is greatly reduced, so the frequency parameter is adjusted according to the frequency adjustment strategy table according to the frequency control strategy table, and the balance between the power consumption and the performance is considered.

In one embodiment, the performing the power consumption control operation according to the frequency control policy table and performing the power consumption control operation according to the core control policy table are performed alternately in sequence, and the performing the power consumption control operation according to the core control policy table includes:

executing an operating system command corresponding to the first intelligent platform management interface command, reading the current processor frequency, and positioning a reference frequency matched with the current processor frequency in the frequency control strategy table;

the power consumption control process starts by adjusting the processor frequency first, so that the bmc first issues a first intelligent platform management interface command to an operating system of the server through the low pin count interface, the operating system executes an operating system command corresponding to the first intelligent platform management interface command, that is, a command for reading the processor frequency, reads the current processor frequency, and locates the current processor frequency in the frequency control policy table to a reference frequency matching the current processor frequency, for example, if the policy parameters in the frequency control policy table are 1.3GHz, 1.5GHz, 1.7GHz, and 1.9GHz, and if the current processor frequency is 1.71GHz, the reference frequency in the frequency control policy table is 1.7 GHz.

reading the current processor frequency, positioning the current processor frequency to a reference frequency in the frequency control strategy table, and then adjusting the processor frequency according to the relation between the complete machine power consumption value and a preset power consumption reference value, wherein the baseboard management controller issues a second intelligent platform management interface command to an operating system of the server through a low pin number interface, and the operating system executes an operating system command corresponding to the second intelligent platform management interface command, namely, a command for setting the processor frequency. If the real-time complete machine power consumption value is higher than the preset power consumption reference value range at the moment, the real-time complete machine power consumption is over high, the frequency of the processor needs to be adjusted downwards to be 1.5GHz on the basis of the reference frequency of 1.7GHz, namely, the direction of adjusting the frequency parameters according to the frequency control strategy table is adjusted along the opposite direction of the real-time complete machine power consumption value deviating from the preset power consumption reference value range, so as to establish a feedback adjusting mechanism.

after executing the operating system command corresponding to the second intelligent platform management interface command to perform frequency adjustment, if the power consumption is still too high, the baseboard management controller issues a third intelligent platform management interface command to the operating system of the server through the low pin number interface, and the operating system executes the operating system command corresponding to the third intelligent platform management interface command, that is, the command for reading the number of processor cores, reads the current number of processor cores, and locates, in the core control policy table, the reference number of cores that matches the current number of processor cores, for example, the policy parameters in the core control policy table are 4, 8, 12, and 16, and the current number of processor cores is 7, and the reference number of cores that is located in the core control policy table is 8.

And executing an operating system command corresponding to the fourth intelligent platform management interface command, and setting the number of started or closed processor cores according to the kernel control policy table along the reverse direction of the real-time complete machine power consumption value deviating from the preset power consumption reference value range on the basis of the reference kernel number.

Reading the current processor core number, positioning the current processor core number to a reference core number in a core control strategy table, and then adjusting the processor core number according to the relation between the complete machine power consumption value and a preset power consumption reference value, wherein the substrate management controller issues a fourth intelligent platform management interface command to an operating system of the server through a low pin number interface, and the operating system executes an operating system command corresponding to the fourth intelligent platform management interface command, namely, a command for setting the processor core number. If the real-time complete machine power consumption value is higher than the preset power consumption reference value range at the moment, the real-time complete machine power consumption is over high, and the number of the cores of the processor needs to be adjusted downwards to be 4 on the basis of the reference number of the cores 8. Therefore, the direction of adjusting the kernel parameters according to the kernel numerical control strategy table is adjusted along the opposite direction of the real-time complete machine power consumption value deviating from the preset power consumption reference value range, so as to establish a feedback adjustment mechanism.

In addition, after the power consumption control strategy corresponding to the operating system command is executed, the operating system acquires an execution result, and if the execution result does not contain information that the power consumption control strategy is successfully executed, the operating system repeatedly issues a corresponding operating system instruction, and re-executes the power consumption control strategy corresponding to the operating system command. The power consumption control result executed by the power consumption control method can be displayed on an interface of the baseboard management controller, and the power consumption control result comprises a real-time power consumption value, a set frequency and kernel number information.

In one embodiment, the frequency adjustment parameter in the frequency control policy table includes a frequency step value, the core adjustment parameter in the core control policy table includes a core number step value, and the establishing the power consumption control policy table further includes:

The frequency adjustment and the core number adjustment are mutually matched in the process of performing power consumption control by adjusting the frequency and alternately performing the power consumption control by adjusting the core number, and the step value of the frequency adjustment is matched with the step value of the core number adjustment, namely, the whole machine power consumption fluctuation generated by adjusting the frequency once according to the frequency step value is close to the whole machine power consumption fluctuation generated by adjusting the core once according to the core number step value, so that the real-time whole machine power consumption can be changed stably when the power consumption control operation is executed according to the frequency control strategy table and the power consumption control operation is sequentially and alternately executed according to the core control strategy table, and the performance of a processor can be considered. In addition, the frequency stepping value and the kernel number stepping value can be determined according to specific actual requirements, the frequency stepping values in the same frequency control strategy table can be consistent, or different frequency stepping values are set in different frequency segments; the step values of the kernel numbers in the same kernel control policy table may be consistent, or different kernel number step values may be set for different kernel number segments.

Example two:

referring to fig. 2 and 4, fig. 2 is a flowchart illustrating a second method of the power consumption control method of the ARM platform server according to the present invention, and fig. 4 is a topology structure diagram illustrating a power consumption control system of the ARM platform server according to the present invention.

Receiving a preset power consumption reference value set by a user on an interface of the baseboard management controller;

the method comprises the steps that a preset power consumption reference value can be set on an interface of a baseboard management controller, a user sets the corresponding preset power consumption reference value according to actual configuration of a server, and then the preset power consumption reference value can be obtained from the baseboard management controller when power consumption control is conducted, so that the real-time power consumption value of the whole machine can be compared with the preset power consumption reference value conveniently.

in order to control the power consumption, a comparison mechanism between a real-time complete machine power consumption value and a preset reference value is established, a power consumption feedback mechanism is established by adjusting the frequency or the number of processor cores in the process of the processor working according to the comparison mechanism, and the power consumption control function is realized through the power consumption feedback mechanism. Therefore, a real-time complete machine power consumption value of the server is obtained firstly, and the method for obtaining the real-time complete machine power consumption value is as follows: and the baseboard management controller acquires a real-time complete machine power consumption value from a power supply of the server through the PMbus. After the real-time complete machine power consumption value is obtained, the real-time complete machine power consumption value can be compared with the preset power consumption reference value to obtain the relation between the real-time complete machine power consumption value and the preset power consumption reference value, and a power consumption feedback regulation mechanism of an ARM platform is conveniently established.

under normal conditions, the real-time power consumption value of the whole machine is within the range of the preset power consumption reference value, and the server does not need to control the power consumption. In order to reasonably use resources to the maximum extent and reduce the waste of resources, a power consumption feedback mechanism needs to be established, when the real-time complete machine power consumption value deviates from a preset power consumption reference value, that is, when the real-time complete machine power consumption value is not within the range of the preset power consumption reference value (including two cases that the real-time complete machine power consumption value is greater than the preset power consumption reference value and the real-time complete machine power consumption value is less than the preset power consumption reference value), the real-time complete machine power consumption value needs to be adjusted through the power consumption feedback mechanism, so that the real-time complete machine power consumption value is kept within the normal range of the preset power consumption reference value. For the ARM platform, there is no power consumption control managed by ME similar to the x86 platform, so the invention issues an intelligent platform management interface command to the operating system of the server through a low pin count interface by the baseboard management controller to implement communication with the operating system, and further performs frequency adjustment or kernel count adjustment (turning on or off the processor kernel) by turning on the kernel interface of the processor through the operating system.

when the baseboard management controller issues an intelligent platform management interface command to an operating system of a server through a low pin number interface, the operating system command corresponding to the intelligent platform management interface command can be obtained from the command mapping script, and the mapping relation between the intelligent platform management interface command and the operating system command is stored in the mapping script file, so that before the operating system command corresponding to the intelligent platform management interface command is obtained from the command mapping script, the mapping relation between the intelligent platform management interface command and the operating system command needs to be established in advance and stored in the command mapping script.

after the baseboard management controller issues an intelligent platform management interface command to an operating system of the server through a low pin number interface, interruption is triggered, so that the operating system executes an interruption processing program, namely, executes a corresponding operating system command. The command mapping script stores the mapping relation between the intelligent platform management interface command and the operating system command, the operating system command corresponding to the intelligent platform management interface command is obtained through the command mapping script, then the operating system executes the operating system command corresponding to the intelligent platform management interface command and issued by the substrate management controller, and the operating system command can trigger related frequency adjustment or kernel number adjustment.

Executing an operating system command corresponding to the third intelligent platform management interface command, reading the number of currently started processor cores, and positioning a reference core number matched with the number of currently started processor cores in the core control strategy table;

after executing the operating system command corresponding to the second intelligent platform management interface command to perform frequency adjustment, if the power consumption is still too high, the baseboard management controller issues a third intelligent platform management interface command to the operating system of the server through the low pin number interface, and the operating system executes the operating system command corresponding to the third intelligent platform management interface command, that is, the command for reading the number of processor cores, reads the current number of processor cores, and locates, in the core control policy table, the reference number of cores that matches the current number of processor cores, for example, the policy parameters in the core control policy table are 4, 8, 12, and 16, and the current processor frequency is 7, and then locates the reference frequency in the frequency control policy table to be 8.

It should be understood that although the various steps in the flow charts of fig. 1-2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-2 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

Example three:

referring to fig. 3, fig. 3 is a system structure diagram of the power consumption control system of the ARM platform server according to the present invention.

The power consumption control system of the ARM platform server comprises a power supply, a substrate management controller, an operating system and a processor, wherein the power supply is in communication connection with the substrate management controller through a power management bus, and the substrate management controller is in communication connection with the operating system through a low pin count interface;

the baseboard management controller comprises:

in order to control the power consumption, a comparison mechanism between a real-time complete machine power consumption value and a preset reference value is established through a power consumption value module, a power consumption feedback mechanism is established by adjusting the frequency or adjusting the number of processor cores of a processor which normally works according to the comparison mechanism, and the power consumption control function is realized through the power consumption feedback mechanism. Therefore, the real-time power consumption value of the whole machine of the server is firstly obtained through the power consumption value module, and the mode of obtaining the real-time power consumption value of the whole machine is as follows: and the baseboard management controller acquires a real-time complete machine power consumption value from a power supply of the server through the PMbus. After the real-time complete machine power consumption value is obtained, the real-time complete machine power consumption value can be compared with the preset power consumption reference value to obtain the relation between the real-time complete machine power consumption value and the preset power consumption reference value, and a power consumption feedback regulation mechanism of an ARM platform is conveniently established. In addition, the power consumption value module is further used for receiving a preset power consumption reference value set by a user.

under normal conditions, the real-time power consumption value of the whole machine is within the range of the preset power consumption reference value, and the server does not need to control the power consumption. In order to reasonably use resources to the maximum extent and reduce the waste of resources, a power consumption feedback mechanism needs to be established, when the real-time complete machine power consumption value deviates from a preset power consumption reference value, that is, when the real-time complete machine power consumption value is not within the range of the preset power consumption reference value (including two cases that the real-time complete machine power consumption value is greater than the preset power consumption reference value and the real-time complete machine power consumption value is less than the preset power consumption reference value), the real-time complete machine power consumption value needs to be adjusted through the power consumption feedback mechanism, so that the real-time complete machine power consumption value is kept within the normal range of the preset power consumption reference value. For the ARM platform, the power consumption control similar to that of the x86 platform managed by the ME is not performed, so that the intelligent platform management interface command is issued to the operating system of the server through the command issuing module to realize communication with the operating system.

The result display module is used for displaying the power consumption control result;

the power consumption control result executed by the power consumption control method can be displayed on an interface of the baseboard management controller through a result display module, and the power consumption control result comprises a real-time power consumption value, and set frequency and kernel number information.

And the power consumption control switch module is used for setting whether the power consumption control switch needs to be opened or not.

The power consumption control switch module can set the on or off of the power consumption control method in the baseboard management controller, and the power consumption control method is allowed to be executed when the power consumption control method is started.

The operating system includes:

and the power consumption control strategy module is used for acquiring a power consumption control strategy table corresponding to the operating system command and executing the operating system command according to the power consumption control strategy table so as to control the power consumption.

After the operating system command corresponding to the intelligent platform management interface command is obtained from the command mapping script, the operating system command needs to be executed to control power consumption. After the operating system command is acquired, the power consumption control strategy table corresponding to the operating system command can be acquired through the power consumption control strategy module according to the operating system command, and the power consumption control strategy table stores parameters for frequency adjustment and parameters for kernel number adjustment, so that corresponding power consumption control can be performed by executing the operating system command according to the power consumption control strategy table, namely, the adjustment of processor frequency and/or the adjustment of kernel number.

The power consumption control system further includes:

the command mapping module is used for acquiring an operating system command corresponding to the intelligent platform management interface command from a command mapping script;

the command mapping module can establish a mapping relation between an intelligent platform management interface command and an operating system command, and the baseboard management controller issues the intelligent platform management interface command to an operating system of the server through a low pin number interface so as to trigger interruption, so that the operating system executes an interruption processing program, namely, executes the corresponding operating system command. The command mapping script stores the mapping relation between the intelligent platform management interface command and the operating system command, the operating system command corresponding to the intelligent platform management interface command is obtained through the command mapping module, then the operating system executes the operating system command corresponding to the intelligent platform management interface command and issued by the baseboard management controller, and the operating system command can execute relevant frequency adjustment or kernel number adjustment.

And the strategy table module is used for establishing a power consumption control strategy table.

In order to adjust the frequency or the number of cores according to a set power consumption control strategy, the power consumption control strategy is preset, and therefore, before a power consumption control strategy table corresponding to an operating system command is obtained, a power consumption control strategy table, namely, a frequency control strategy table and a core control strategy table, is preset through a strategy table module, so that power consumption control is performed according to strategy parameters in the power consumption control strategy table.
