[0026] 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. It is understood that the specific embodiments described herein are only used to explain the related applications, rather than to limit the applications. It should also be noted that, for ease of description, only the parts related to the related applications are shown in the drawings.

[0027] Server power consumption usually involves two working states: C state and P state; among them, C state is used to describe the processor sleep state, which is generally divided into normal working state, shallow sleep state, deep sleep state, etc. (taking Intel processor as an example, C0 represents normal working state, C1 / C1E represents shallow sleep, C3 / C6 represents deep sleep, the larger the number, the more circuit units are offline, the lower the power consumption, but the longer the wake-up time is); P state represents the processor energy efficiency state, which is divided into acceleration state, base frequency state, and frequency modulation state (taking Intel processor as an example, P1 represents working at the base frequency, P0 represents entering the turbo acceleration mode, the operating frequency is higher than the base frequency, which is a short-term state, P2~Pn represents running at different frequencies, the larger the number, the lower the frequency, but it is not linear, but automatically adjusted in steps of 100Mhz or 133MHz).

[0028] Currently, the C state and P state of the server are not adjusted by the server itself, but with the participation of the operating system kernel, the software and hardware jointly complete the adjustment of different operating states. Figure 1 Schematic diagram of the support status of processors in related technologies, such as Figure 1 As shown in the figure, the support status of Intel, Hygon, and ARM processors is also described.

[0029] The Basic Input Output System (BIOS) options of the server motherboard include switches for C state and P state (the sleep switch allows the C1 to Cn states to be turned on or off individually, the acceleration switch allows the P0 state to be turned on or off, and the energy-saving switch can set the performance mode or energy-efficiency mode. The performance mode works constantly in the P1 state, and the energy-efficiency mode automatically adjusts the frequency according to the load in the P1 to Pn states). When a certain function is enabled, the operating system kernel can call these two capabilities of the processor to achieve automatic control of sleep and frequency.

[0030] There are two types of drivers in the operating kernel: idledriver implements automatic sleep, and cpufreq driver implements automatic frequency regulation. These two drivers have multiple regulators to achieve different regulation effects, and depending on the processor, there are certain differences between the driver and regulator.

[0031] In summary, with the cooperation of software and hardware, the above mechanism can be used to realize automatic CPU sleep and automatic frequency adjustment, thereby reducing some power consumption while meeting business performance.

[0032] However, the regulation efficiency of the operating system kernel is low. The operating system kernel usually detects CPU utilization in a period of 10 milliseconds and uses CPU utilization as a basis for automatic sleep and automatic frequency adjustment. The CPU regulation efficiency is much higher than that of the operating system. The longest CPU sleep and wake-up time (in deep sleep) is no more than 100 microseconds, and the frequency adjustment delay is less than 1 millisecond. Therefore, the operating system becomes a bottleneck, resulting in a decrease in energy saving effect. At the same time, the power consumption / performance ratio is not considered, and there is still room for optimization of energy saving effect: the lower the CPU frequency, the lower the power consumption and the lower the performance. However, the power consumption under unit performance (i.e., energy efficiency ratio) is not the lower the frequency, the better, but it is best at a certain frequency (which varies with different processors). Figure 2 Schematic diagram of the power consumption of a processor in the related art. Figure 2 As shown, taking the Intel 6230N processor as an example, the power consumption is lowest when the main frequency is adjusted until the CPU utilization is between 50% and 70% while keeping the performance constant.

[0033] In order to solve the problem that the current operating system has become a bottleneck, thereby causing a decrease in energy saving effect, the embodiment of the present application provides a parameter adjustment method, a first device, a storage medium and a computer program product, the method is applied to the first device, the first device includes a CPU, the method includes: the CPU generates a first strategy based on the first parameter; wherein the first strategy is used to trigger the adjustment of the state parameters of the CPU, the state parameters at least include the sleep state of the CPU, and / or the operating frequency of the CPU; the CPU determines whether the triggering condition of the first strategy is met based on the running state data, and automatically adjusts the state parameters of the CPU based on the first strategy when the triggering condition is met. It can be seen that the CPU of the embodiment of the present application can generate a first strategy based on the first parameter, the strategy is used to trigger the adjustment of the state parameters of the CPU, and then the CPU can determine whether the triggering condition of the first strategy is met based on the running state data, and when the triggering condition is met, the state parameters of the CPU can be automatically adjusted based on the first strategy, that is, the embodiment of the present application can automatically adjust the running state parameters through the CPU, so that the running state parameters can be maintained within a set range to achieve the best energy saving effect.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] The embodiment of the present application provides a parameter adjustment method, which is applied to a first device, wherein the first device includes a CPU, Figure 3 The parameter adjustment method proposed in this embodiment is shown in FIG. Figure 1 ,like Figure 3 As shown, the parameter adjustment method may include the following steps:

[0036] Step 101: The CPU generates a first strategy based on a first parameter; wherein the first strategy is used to trigger adjustment processing of a state parameter of the CPU, and the state parameter at least includes a sleep state of the CPU and / or an operating frequency of the CPU.

[0037] In an embodiment of the present application, a CPU in the first device may generate a first policy based on a first parameter.

[0038] It should be noted that, in the embodiments of the present application, the first device may be a server or other devices, and the present application does not specifically limit the device type of the first device.

[0039] It should be noted that, in an embodiment of the present application, the first parameter may include one or more of the CPU utilization range, the first preset threshold and the second preset threshold, the first preset threshold includes the threshold for the CPU to enter light sleep, and the second preset threshold includes the threshold for the CPU to enter deep sleep. The present application does not specifically limit the parameter type and number of parameters included in the first parameter.

[0040] It should be noted that, in the embodiments of the present application, the state parameters include at least the sleep state of the CPU and / or the operating frequency of the CPU. The present application does not specifically limit the parameter type and number of parameters included in the state parameters.

[0041] It should be noted that, in the embodiments of the present application, the CPU may include a first circuit unit and a second circuit unit, and the present application does not specifically limit the number of circuit units included in the CPU.

The present application does not specifically limit the structure and function of the second circuit unit.

[0044] Further, in an embodiment of the present application, when the CPU generates a first strategy based on a first parameter, the first circuit unit may receive the first parameter sent by the operating system kernel; wherein the first parameter includes one or more of a CPU utilization range, a first preset threshold, and a second preset threshold, the first preset threshold includes a threshold for the CPU to enter shallow sleep, and the second preset threshold includes a threshold for the CPU to enter deep sleep; then the first circuit unit may generate a first strategy based on the first parameter, and send the first strategy to the second circuit unit.

[0045] It should be noted that, in an embodiment of the present application, when the first circuit unit generates the first strategy based on the first parameter, the first circuit unit may first verify the validity of the first parameter to obtain a verification result; if the verification result indicates that the first strategy is passed, the first strategy may then be generated based on the first parameter.

[0046] Exemplarily, in an embodiment of the present application, when the first circuit unit verifies the validity of the first parameter, it can determine whether the value in the first parameter is correct, for example, whether the information in the first parameter is information supported by the CPU. If so, it can be determined that the verification has passed.

[0047] It should be noted that, in an embodiment of the present application, the first strategy may include a second strategy, and the second strategy is at least used to adjust the current operating frequency of the CPU. The present application does not specifically limit the number and type of strategies included in the first strategy.

[0048] It should be noted that, in an embodiment of the present application, when the first circuit unit generates the first strategy based on the first parameter, when the CPU utilization is greater than the upper limit value of the CPU utilization range and the current operating frequency of the CPU is not the maximum operating frequency supported by the CPU, the current operating frequency can be increased based on the preset adjustment step; when the CPU utilization is less than the lower limit value of the CPU utilization range and the current operating frequency of the CPU is not the minimum operating frequency supported by the CPU, the current operating frequency can be decreased based on the preset adjustment step; when the CPU utilization is greater than the lower limit value and less than the upper limit value, the current operating frequency of the CPU can be kept unchanged.

[0049] It should be noted that, in the embodiments of the present application, assuming that the CPU utilization range in the first parameter is set to 10%-30%, the upper limit value of the CPU utilization range may be 30%, and the lower limit value of the CPU utilization range may be 10%. The present application does not specifically limit the setting size of the CPU utilization range.

[0050] It should be noted that in the embodiments of the present application, the preset adjustment step size can be automatically generated by the CPU according to its own characteristics, which is generally a multiple of the frequency, the frequency difference of each increase or decrease, and the present application does not specifically limit the size of the preset adjustment step size.

[0051] That is to say, in an embodiment of the present application, the first circuit unit in the CPU can generate a second strategy based on the first parameter, that is, the CPU utilization and the upper and lower limit values ​​of the CPU utilization range in the first parameter can be compared and processed, and then the CPU operating frequency can be adjusted based on the comparison result, so that the CPU operating frequency can be set within a reasonable range, thereby improving the energy saving effect of the CPU.

[0052] It should be noted that, in the embodiments of the present application, the first strategy may include not only the second strategy but also a third strategy, and the third strategy is at least used to adjust the sleep state of the CPU. The present application does not specifically limit the number and type of strategies included in the first strategy.

[0053] It should be noted that, in an embodiment of the present application, when the first circuit unit in the CPU generates a first strategy based on the first parameter, the CPU can be controlled to enter a shallow sleep state when the number of idle sampling cycles of the CPU is equal to a first preset threshold; wherein the number of idle sampling cycles at least includes the number of idle clock cycles; when the number of idle sampling cycles of the CPU is greater than or equal to a second preset threshold, the CPU can be controlled to enter a deep sleep state; when the number of idle sampling cycles of the CPU is greater than the first preset threshold and less than the second preset threshold, the CPU can be controlled to enter a shallow sleep state.

[0054] It should be noted that, in an embodiment of the present application, the first preset threshold includes a threshold for the CPU to enter shallow sleep. For example, the size of the first preset threshold can be set to the CPU idle time being N1 sampling cycles. The present application does not specifically limit the size of the first preset threshold.

[0055] It should be noted that, in an embodiment of the present application, the second preset threshold includes a threshold for the CPU to enter deep sleep. For example, the size of the second preset threshold can be set to the CPU idle time being N2 sampling cycles. The present application does not specifically limit the size of the second preset threshold.

[0056] That is to say, in an embodiment of the present application, the first circuit unit in the CPU can also generate a third strategy based on the first parameter, that is, the number of idle sampling cycles of the CPU can be compared with the size of the first preset threshold and the size of the second preset threshold, and then the CPU can be controlled to enter a corresponding sleep state based on the comparison result, thereby improving the energy saving effect of the CPU.

[0057] Step 102: The CPU determines whether a trigger condition of a first strategy is met based on the running status data. If the trigger condition is met, the CPU status parameters are automatically adjusted based on the first strategy.

[0058] In an embodiment of the present application, after the CPU in the first device generates the first strategy based on the first parameter, it can determine whether the trigger condition of the first strategy is met based on the operating status data, and automatically adjust the status parameters of the CPU based on the first strategy when the trigger condition is met.

[0059] It should be noted that, in the embodiments of the present application, the CPU may include a third circuit unit in addition to the first circuit unit and the second circuit unit. The present application does not specifically limit the number of circuit units included in the CPU.

[0060] It should be noted that, in the embodiments of the present application, the third circuit unit may be a monitor, whose main function is to monitor the CPU working status and provide a basis for whether to execute the first strategy. The present application does not specifically limit the structure and function of the third circuit unit.

[0061] It should be noted that in the embodiments of the present application, the operating status data may include the CPU utilization, the total number of clock cycles corresponding to one or more circuit units in the CPU, the number of active clock cycles, etc. The present application does not specifically limit the type of data and the amount of data contained in the CPU operating status data.

[0062] Further, in an embodiment of the present application, the second circuit unit can receive first data sent by the third circuit unit; wherein the first data at least includes the total number of clock cycles and the number of active clock cycles corresponding to one or more circuit units in the CPU; then the second circuit unit can determine second data based on the first data; wherein the second data at least includes the utilization rate of the CPU; and then the second circuit unit can generate operating status data based on the first data and / or the second data.

[0063] It should be noted that, in an embodiment of the present application, when the second circuit unit determines the second data based on the first data, it can obtain the CPU utilization by dividing the number of active time cycles by the total number of clock cycles. The present application does not specifically limit the calculation method of the CPU utilization.

[0064] It should be noted that, in an embodiment of the present application, the first data may also include the number of idle clock cycles corresponding to one or more circuit units, and the present application does not specifically limit the type and quantity of data included in the first data.

[0065] It should be noted that, in the embodiment of the present application, after generating the running status data, the CPU may determine whether the triggering condition of the first strategy is met based on the running status data.

[0066] Further, in an embodiment of the present application, when the CPU determines whether the triggering condition of the first strategy is met based on the operating status data, the second circuit unit may compare the number of idle clock cycles contained in the first data with the first preset threshold and the second preset threshold, respectively, to obtain a first comparison result, and compare the CPU utilization contained in the second data with the upper limit value of the CPU utilization range and the lower limit value of the CPU utilization range, respectively, to obtain a second comparison result; then the second circuit unit may determine whether the triggering condition of the first strategy is met based on the first comparison result and / or the second comparison result.

[0067] It should be noted that, in an embodiment of the present application, when the second circuit unit determines whether the trigger condition of the first strategy is met based on the first comparison result and / or the second comparison result, the second circuit unit may match the first comparison result with the third strategy to obtain a first matching result; when the first matching result indicates a successful match, it is determined that the trigger condition of the first strategy is met; and / or, the second circuit unit may also match the second comparison result with the second strategy to obtain a second matching result; when the second matching result indicates a successful match, it is determined that the trigger condition of the first strategy is met.

[0068] Exemplarily, in an embodiment of the present application, when the second circuit unit determines whether the trigger condition of the first strategy is met based on the first comparison result and / or the second comparison result, assuming that the first comparison result is that the number of idle clock cycles contained in the first data is equal to the first preset threshold, the second circuit unit can match the first comparison result with the third strategy, and if it is found that the situation matches the third strategy that when the number of idle sampling cycles of the CPU is equal to the first preset threshold, the CPU can be controlled to enter a shallow sleep state, then it indicates that the first matching result indicates that the match is successful, and it can be determined that the trigger condition of the first strategy is met.

[0069] It should be noted that, in the embodiment of the present application, when the first matching result indicates that the match is unsuccessful, it is determined that the trigger condition of the first strategy is not met; and / or when the second matching result indicates that the match is unsuccessful, it is determined that the trigger condition of the first strategy is not met, then the automatic adjustment processing of the CPU state parameters based on the first strategy is prohibited.

[0070] It should be noted that in an embodiment of the present application, the second circuit unit can automatically adjust the CPU state parameters based on the first strategy after determining that the trigger condition of the first strategy is met based on the first comparison result and / or the second comparison result.

[0071] Further, in an embodiment of the present application, when the second circuit unit automatically adjusts the state parameters of the CPU based on the first strategy, the second circuit unit may adjust the current operating frequency of the CPU based on the second strategy; and / or, the second circuit unit may also adjust the sleep state of the CPU based on the third strategy.

[0072] That is to say, in an embodiment of the present application, the second circuit unit in the CPU can determine whether the trigger condition of the first strategy is met based on the operating status data, that is, the number of idle clock cycles contained in the first data can be compared with the first preset threshold and the second preset threshold respectively to obtain a first comparison result, and the CPU utilization contained in the second data can be compared with the upper limit value of the CPU utilization range and the lower limit value of the CPU utilization range respectively to obtain a second comparison result; then the second circuit unit matches the first comparison result with the third strategy to obtain a first matching result; when the first matching result indicates a successful match, it is determined that the trigger condition of the first strategy is met; and / or, the second circuit unit matches the second comparison result with the second strategy to obtain a second matching result; when the second matching result indicates a successful match, it is determined that the trigger condition of the first strategy is met, and then the second circuit unit can adjust the current operating frequency of the CPU based on the second strategy; and / or, adjust the sleep state of the CPU based on the third strategy, so that the current operating frequency of the CPU can be reduced; and / or, the sleep state of the CPU is automatically adjusted to the optimal state, so that the CPU energy saving effect is optimized.

[0073] In summary, the embodiment of the present application can add three circuit units in the CPU, including a first circuit unit, a second circuit unit and a third circuit unit respectively. The first circuit unit in the CPU can generate a second strategy based on the first parameter, that is, the CPU utilization rate can be compared with the upper and lower limits of the CPU utilization rate range in the first parameter, and then the CPU operating frequency can be adjusted based on the comparison result, so that the CPU operating frequency can be set within a reasonable range; the first circuit unit in the CPU can also generate a third strategy based on the first parameter, that is, the number of idle sampling cycles of the CPU can be compared with the size of the first preset threshold and the size of the second preset threshold, and then the CPU can be controlled to enter a corresponding sleep state based on the comparison result, so that the energy saving effect of the CPU can be improved, and then the second circuit unit in the CPU can determine whether the triggering condition of the first strategy is met based on the running state data; wherein, the first strategy includes the second strategy and the third strategy, and when it is determined that the triggering condition of the first strategy is met, the second circuit unit can adjust the current operating frequency of the CPU based on the second strategy; and / or, adjust the sleep state of the CPU based on the third strategy, so that the current operating frequency of the CPU can be adjusted; and / or, the sleep state of the CPU is automatically adjusted to the optimal state, so that the CPU energy saving effect is optimal.

[0074] The embodiment of the present application provides a parameter adjustment method, a first device, a storage medium and a computer program product, the method is applied to the first device, the first device includes a CPU, the method includes: the CPU generates a first strategy based on the first parameter; wherein the first strategy is used to trigger the adjustment of the state parameters of the CPU, the state parameters at least include the sleep state of the CPU, and / or the operating frequency of the CPU; the CPU determines whether the triggering condition of the first strategy is met based on the running state data, and automatically adjusts the state parameters of the CPU based on the first strategy when the triggering condition is met. It can be seen that the CPU of the embodiment of the present application can generate a first strategy based on the first parameter, the strategy is used to trigger the adjustment of the state parameters of the CPU, and then the CPU can determine whether the triggering condition of the first strategy is met based on the running state data, and when the triggering condition is met, the state parameters of the CPU can be automatically adjusted based on the first strategy, that is, the embodiment of the present application can automatically adjust the running state parameters through the CPU, so that the running state parameters can be maintained within a set range to achieve the best energy saving effect.

[0075] Based on the above embodiments, another embodiment of the present application provides a parameter adjustment method, which can be improved by the CPU, that is, three circuit units can be added to the CPU, which can be a manager (i.e., a first circuit unit), a monitor (i.e., a third circuit unit) and a regulator (i.e., a second circuit unit), so as to realize the hardware-based self-adjustment capability for CPU utilization to achieve the best energy saving effect; Figure 4 Schematic diagram of the CPU structure proposed in this application embodiment Figure 1 ,like Figure 4 As shown, the embodiment of the present application adds three circuit units to the CPU, which can be a manager, a monitor and a regulator respectively; among them, the manager can provide an interface for the operating system kernel, allowing the user to set the working parameters of the processor (i.e., CPU); the monitor can monitor the working status of the CPU and provide a basis for whether to execute the energy-saving trigger strategy (i.e., the first strategy); the regulator can automatically adjust the operating status parameters of the CPU.

[0076] It should be noted that in the embodiments of the present application, by introducing a monitor (i.e., the third circuit unit) and a regulator (i.e., the second circuit unit) in the CPU, hardware-controlled automatic frequency regulation can be achieved, thereby adjusting the CPU to the utilization rate with the best energy efficiency ratio, and hardware-controlled automatic sleep can also be achieved, thereby achieving energy consumption when there is no business activity.

[0077] It should be noted that in the embodiment of the present application, the manager (i.e., the first circuit unit) can provide an interface for the operating system kernel, so that the user can set the operating parameters of the processor (i.e., the first parameter), and generate an energy-saving trigger strategy (i.e., the first strategy) according to the set parameters (i.e., the first parameter). The manager receives the energy-saving strategy parameters (i.e., the first parameter) transmitted by the user operating system kernel. The energy-saving strategy parameters (i.e., the first parameter) include the capability switch, the anchor utilization range (optional, which can be automatically generated by the processor according to its own characteristics, including a CPU utilization range. If the current CPU utilization exceeds its upper limit, the frequency is increased by one step to the highest frequency supported, and if it is lower than its lower limit, the frequency is decreased by one step to the lowest frequency supported), the frequency adjustment step (optional, which can be automatically generated by the processor according to its own characteristics, generally a multiplier, and the frequency difference of each increase or decrease), the threshold for entering shallow sleep (i.e., the first preset threshold) (optional, which can be automatically generated by the processor according to its own characteristics, and the CPU idle time is N1 sampling cycles), and the threshold for entering deep sleep (i.e., the second preset threshold) (optional, which can be automatically generated by the processor according to its own characteristics, The CPU idle time is N2 sampling cycles), data sampling cycle (optional, can be automatically generated by the processor according to its own characteristics, the number of clock cycles, as the basis for frequency modulation or sleep), etc. The manager (i.e., the first circuit unit) is responsible for checking the validity of the incoming parameters (i.e., the first parameters). If the parameter value is correct (such as the step size is a value supported by the CPU), the energy-saving trigger strategy is set (such as the above parameters, setting strategy 1 (i.e., the second strategy): if the CPU utilization exceeds the upper limit of the anchor utilization within a sampling cycle and the frequency is not the supported maximum value, the frequency is increased by one step; if the CPU utilization is lower than the lower limit of the anchor utilization within a sampling cycle and the frequency is not the supported minimum value, the frequency is reduced by one step; strategy 2 (i.e., the third strategy): if the CPU is idle for N1 sampling cycles, it will enter light sleep; if the CPU is idle for N2 sampling cycles, it will enter deep sleep).

[0078] It should be noted that, in an embodiment of the present application, when the CPU generates a first strategy based on a first parameter, the first circuit unit can receive the first parameter sent by the operating system kernel; wherein the first parameter includes one or more of the CPU utilization range, a first preset threshold and a second preset threshold, the first preset threshold includes the threshold for the CPU to enter shallow sleep, and the second preset threshold includes the threshold for the CPU to enter deep sleep; then the first circuit unit can generate a first strategy based on the first parameter, and send the first strategy to the second circuit unit.
