Description
Technical Field
The invention belongs to the technical field of CPU (Central Processing Unit) performance optimization, and particularly relates to a CPU power consumption limit optimization method and electronic equipment.
Background
The CPU frequency, which is the clock frequency when the CPU core is working, has a main frequency and a Rui frequency. The main frequency of the CPU represents the oscillation speed of the digital pulse signal in the CPU, and the main frequency has no direct relation with the actual operational capability of the CPU; the CPU frequency is a technology that after an operation program is started, the processor can automatically accelerate to a proper frequency, so that the original operation speed can be increased by 10-20% to ensure the smooth operation of the program, and the maximum frequency is the highest frequency which can be reached when the CPU frequency is automatically turned.
The CPU has two Power consumption values of PL1 and PL2 corresponding to the main frequency and the maximum turbo frequency, and at present, the Power consumption value PL1 corresponding to the main frequency of the CPU is TDP (Thermal Design Power) and the Power consumption value PL2 corresponding to the maximum turbo frequency of the CPU is PL1 × 1.2 by default. According to this definition, after the CPU is pressurized such that the Rui _ Frequency rises to trigger the PL2 (i.e., the power consumption value corresponding to the Rui _ Frequency reaches the PL2), the frequency is pulled down. However, in practical applications, the default PL2 value, i.e. the power consumption value corresponding to the maximum turbo frequency, often does not reach the optimum value, i.e. from the design point of the hardware platform of the device or the heat dissipation design, etc., the CPU may be able to support the higher turbo frequency, however, due to the limitation of the PL2 value, the CPU may not reach the higher turbo frequency. In response to this problem, the prior art often adopts a manual setting mode with multiple attempts to change the value of the PL2 so as to optimize the value of the PL 2.
However, the method for manually setting the PL2 value to optimize the PL2 value is not convenient enough, and meanwhile, the method for manually setting the PL2 value has poor safety, so that the CPU can run under unsafe power consumption, and the CPU is damaged.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a first embodiment of a method for optimizing a CPU power consumption limit, which may be applied to an electronic device, where the electronic device may be various intelligent terminals such as a smart phone and a tablet computer, or may also be various computer devices such as a notebook, a desktop, and an all-in-one machine, as shown in fig. 1, the method includes the following steps:
The optimization instruction is used for indicating that the CPU power limit value corresponding to the maximum Rui frequency of the CPU of the electronic equipment is optimized, so that the CPU can be supported to automatically Rui frequency to higher frequency, and the requirement of the program on the higher Rui frequency of the CPU during running is further met.
The optimization instruction may be triggered by a user of the electronic device by performing a corresponding operation on an interface of the electronic device, or may also be triggered automatically by the electronic device, which is not limited in this embodiment.
And 102, acquiring parameter information of the maximum clock frequency which can be supported by the CPU and a preset safety parameter of the CPU.
After the optimization instruction is obtained, the instruction is responded to optimize the CPU power consumption limit value corresponding to the maximum Rui frequency of the CPU.
In response to the instruction, the present embodiment first obtains the maximum clock frequency that can be supported by the CPU, so as to provide a required data basis for optimizing the CPU power consumption limit, and meanwhile, in view of safety, in order to avoid that the CPU runs under an unsafe condition, such as running under an unsafe power consumption or running under an unsafe heat dissipation condition, during the process of optimizing the CPU power consumption limit, the present embodiment also obtains parameter information of a predetermined safety parameter, so as to provide required safety reference information for optimizing the CPU power consumption limit.
The parameter information of the predetermined safety parameter may correspondingly include, but is not limited to, a safety power consumption threshold value and a safety heat dissipation parameter threshold value of the CPU.
And 103, optimizing the power consumption limit value of the CPU based on the maximum clock frequency and the parameter information of the preset safety parameter.
On the basis of the above steps, this step optimizes the CPU power consumption limit corresponding to the maximum frequency of the CPU based on the obtained maximum clock frequency and the parameter information of the predetermined safety parameter, such as a safety power consumption threshold, a safety heat dissipation parameter threshold, and the like, so that the CPU can be subjected to turbo-frequency to a higher frequency based on the optimized power consumption limit when the subsequent CPU is subjected to auto-turbo-frequency.
Based on the above scheme, it can be known that, according to the method for optimizing the power consumption limit of the CPU disclosed in the present application, after the optimization instruction for instructing to optimize the power consumption limit of the CPU is obtained, the maximum clock frequency that can be supported by the CPU and the parameter information of the predetermined safety parameter of the CPU are obtained, and the power consumption limit of the CPU corresponding to the maximum frequency of the CPU is optimized based on the maximum clock frequency and the parameter information of the predetermined safety parameter. Therefore, the scheme for automatically optimizing the power consumption limit value of the CPU corresponding to the maximum Rui frequency of the CPU is provided, compared with a manual optimization mode in the prior art, the automatic mode is more convenient, and in the automatic optimization process, the parameter information of the preset safety parameters of the CPU is considered, so that the CPU can be effectively prevented from running under an unsafe condition, and the safety of the CPU is ensured.
The above-described method of the present application will be described in further detail in the following example two. Referring to fig. 2, fig. 2 is a flowchart of a second embodiment of the method for optimizing the CPU power consumption limit disclosed in the present application, and in the second embodiment, the method may be implemented by the following processing procedures:
In this embodiment, preferably, the optimization instruction is triggered in an automatic triggering manner, that is, the optimization instruction for indicating the power consumption limit of the CPU is automatically triggered by the electronic device. As a possible implementation manner, in the embodiment, the optimization instruction is preferably automatically triggered by the electronic device in the BIOS self-checking process.
Then, this step correspondingly obtains the optimized instruction during the BIOS self-test, and then, the instruction may be responded by executing the following steps of the method of this embodiment, so as to optimize the CPU power consumption limit corresponding to the maximum frequency of the CPU.
After the optimization instruction is obtained, in order to respond to the instruction, the maximum clock frequency which can be supported by the CPU is obtained in the step, so that a required data basis is provided for optimizing the power consumption limit value of the CPU; and meanwhile, parameter information of preset safety parameters such as a safety power consumption threshold value and a safety heat dissipation parameter threshold value of the CPU is obtained, so that required safety reference information is provided for optimizing the CPU power consumption limit value.
And 203, under the condition that the heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, gradually pressurizing the CPU so as to gradually increase the clock frequency of the CPU, and stopping pressurizing until the clock frequency of the CPU reaches the maximum clock frequency or the power consumption value of the CPU reaches the safe power consumption threshold.
When the CPU power consumption limit corresponding to the maximum frequency of the CPU is optimized, it is first detected whether the current heat dissipation parameter value of the CPU is lower than the safe heat dissipation parameter threshold, if so, the CPU power consumption limit is no longer optimized for safety, otherwise, if not, the CPU power consumption limit is continuously tested to obtain the optimal CPU power consumption limit.
Specifically, under the condition that the current heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, the clock frequency of the CPU can be gradually increased by gradually pressurizing the CPU, wherein the power consumption value of the CPU is correspondingly gradually increased in the process of continuously pressurizing the CPU to gradually increase the clock frequency of the CPU, so that the optimal limit value that the power consumption of the CPU can reach is dynamically tested.
It should be noted that the optimal CPU power limit should not exceed the safe power threshold of the CPU based on safety considerations, in addition to being able to support the CPU's turbo to higher frequencies. In view of this, in this step, when the heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, the CPU is continuously pressurized, so that in the process of gradually increasing the clock frequency of the CPU, when the clock frequency of the CPU reaches the maximum clock frequency, or the power consumption value of the CPU reaches the safe power consumption threshold, pressurization is stopped, and since the power consumption value of the CPU corresponding to the time when pressurization is stopped can support the CPU to reach the maximum clock frequency, or the power consumption value of the CPU reaches the safe power consumption threshold of the CPU (when pressurization is continued again, the CPU operates under an unsafe power consumption condition), the power consumption value of the CPU at this time can be considered as the optimal power consumption limit value of the CPU.
And step 204, obtaining the CPU power consumption value when the pressurization is stopped, and taking the CPU power consumption value when the pressurization is stopped as the optimized CPU power consumption limit value.
On the basis of the steps, the step obtains the CPU power consumption value when the pressurization is stopped, and takes the CPU power consumption value when the pressurization is stopped as the optimized CPU power consumption limit value, thereby realizing the optimization of the CPU power consumption limit value corresponding to the maximum Rui frequency of the CPU. Subsequently, based on the optimized CPU power consumption limit value, the CPU can be supported to reach higher frequency, and the CPU can be operated under the condition of safe power consumption.
When the method is implemented specifically, a corresponding executable file can be embedded in the BOIS code, and the executable file comprises corresponding codes for realizing each processing step in the method, so that in the power-on self-test process of the electronic equipment, the BIOS can call the executable file to automatically trigger an optimization instruction for indicating the power consumption limit value of the optimized CPU, respond to the instruction to obtain the maximum clock frequency which can be supported by the CPU and the parameter information of the preset safety parameters of the CPU, on the basis, the CPU of the equipment is subjected to a pressurization test, and finally, the optimal power consumption limit value of the CPU is obtained based on the pressurization test process, so that the power consumption limit value of the CPU corresponding to the maximum Rui frequency of the CPU is optimized.
According to the embodiment, the power consumption limit value of the CPU corresponding to the maximum Rui frequency of the CPU is optimized by performing the pressurization test on the CPU in the power-on self-test process of the electronic equipment, and based on the optimized power consumption limit value of the CPU, the Rui frequency of the CPU can be supported to be higher, and the CPU can be operated under the safe power consumption condition.
Referring to fig. 3, fig. 3 is a flowchart of a third embodiment of the method for optimizing the CPU power consumption limit disclosed in the present application, and in the third embodiment, the method may further include the following steps:
Specifically, on the basis of performing a pressurization test on the CPU, obtaining a CPU power consumption value when pressurization is stopped, and taking the CPU power consumption value as an optimized CPU power consumption limit value, the optimized CPU power consumption limit value may be set in a predetermined storage location, for example, may be set in a register corresponding to an MSR of the CPU, so as to replace an original CPU power consumption limit value in the storage location, so that the optimized CPU power consumption limit value becomes effective.
Subsequently, when the CPU core frequency needs to be executed, the optimized CPU power consumption limit value can be read from the storage position, and the core frequency process of the CPU is controlled by utilizing the optimized CPU power consumption limit value. Based on the optimized CPU power consumption limit value, the CPU can be supported to reach higher frequency, and the CPU can be operated under the safe power consumption condition.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a fourth embodiment of an electronic device disclosed in the present application, where the electronic device may be various smart terminals such as a smart phone and a tablet computer, or may also be various computer devices such as a notebook, a desktop, and a kiosk, and as shown in fig. 4, the electronic device includes:
a first obtaining unit 100, configured to obtain an optimization instruction for indicating an optimized CPU power limit, where the CPU power limit corresponds to a maximum core frequency of the CPU.
The optimization instruction is used for indicating that the CPU power limit value corresponding to the maximum Rui frequency of the CPU of the electronic equipment is optimized, so that the CPU can be supported to automatically Rui frequency to higher frequency, and the requirement of the program on the higher Rui frequency of the CPU during running is further met.
The optimization instruction may be triggered by a user of the electronic device by performing a corresponding operation on an interface of the electronic device, or may also be triggered automatically by the electronic device, which is not limited in this embodiment.
A second obtaining unit 200 for obtaining parameter information of a maximum clock frequency that the CPU can support and a predetermined security parameter of the CPU.
After the optimization instruction is obtained, the instruction is responded to optimize the CPU power consumption limit value corresponding to the maximum Rui frequency of the CPU.
In response to the instruction, the present embodiment first obtains the maximum clock frequency that can be supported by the CPU, so as to provide a required data basis for optimizing the CPU power consumption limit, and meanwhile, in view of safety, in order to avoid that the CPU runs under an unsafe condition, such as running under an unsafe power consumption or running under an unsafe heat dissipation condition, during the process of optimizing the CPU power consumption limit, the present embodiment also obtains parameter information of a predetermined safety parameter, so as to provide required safety reference information for optimizing the CPU power consumption limit.
The parameter information of the predetermined safety parameter may correspondingly include, but is not limited to, a safety power consumption threshold value and a safety heat dissipation parameter threshold value of the CPU.
An optimizing unit 300, configured to optimize the CPU power consumption limit value based on the maximum clock frequency and the parameter information of the predetermined safety parameter.
On the basis of the above processing, the CPU power consumption limit corresponding to the maximum core frequency of the CPU may be optimized based on the obtained maximum clock frequency and the parameter information of the predetermined safety parameter, such as a safety power consumption threshold, a safety heat dissipation parameter threshold, and the like, so that when the subsequent CPU is automatically in core frequency, the CPU can be subjected to core frequency to a higher frequency based on the optimized power consumption limit.
Based on the above scheme, it can be seen that, after obtaining the optimization instruction for instructing to optimize the CPU power consumption limit, the electronic device disclosed in the present application obtains the maximum clock frequency that can be supported by the CPU and the parameter information of the predetermined safety parameter of the CPU, and optimizes the CPU power consumption limit corresponding to the maximum frequency of the CPU based on the maximum clock frequency and the parameter information of the predetermined safety parameter. Therefore, the scheme for automatically optimizing the power consumption limit value of the CPU corresponding to the maximum Rui frequency of the CPU is provided, compared with a manual optimization mode in the prior art, the automatic mode is more convenient, and in the automatic optimization process, the parameter information of the preset safety parameters of the CPU is considered, so that the CPU can be effectively prevented from running under an unsafe condition, and the safety of the CPU is ensured.
The detailed explanation of each unit included in the electronic device of the present application is continued in the following fifth embodiment.
In this embodiment, the first obtaining unit 100 in the electronic device is specifically configured to: and in the self-checking process of the BIOS, obtaining an optimization instruction for indicating the limit value of the power consumption of the optimized CPU.
The present embodiment preferably uses an automatic triggering manner to trigger the optimization instruction, that is, the optimization instruction for indicating the optimized CPU power consumption limit is automatically triggered by the electronic device. As a possible implementation manner, in the embodiment, the optimization instruction is preferably automatically triggered by the electronic device in the BIOS self-checking process.
Then, the first obtaining unit 100 correspondingly obtains the optimized instruction in the BIOS self-test process, and then may respond to the optimized instruction by executing the functions provided by other units of the electronic device, so as to optimize the CPU power consumption limit corresponding to the maximum frequency of the CPU.
Correspondingly, the second obtaining unit 200 is specifically configured to: and acquiring the maximum clock frequency which can be supported by the CPU, and acquiring a safe power consumption threshold and a safe heat dissipation parameter threshold of the CPU.
After obtaining the optimization instruction, in order to respond to the instruction, the second obtaining unit 200 obtains the maximum clock frequency that can be supported by the CPU, so as to provide a required data basis for optimizing the power consumption limit value of the CPU; and meanwhile, parameter information of preset safety parameters such as a safety power consumption threshold value and a safety heat dissipation parameter threshold value of the CPU is obtained, so that required safety reference information is provided for optimizing the power consumption limit value of the CPU.
Correspondingly, the optimization unit 300 is specifically configured to: under the condition that the heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, gradually pressurizing the CPU so as to gradually increase the clock frequency of the CPU until the clock frequency of the CPU reaches the maximum clock frequency or the power consumption value of the CPU reaches the safe power consumption threshold, and stopping pressurizing; and obtaining the CPU power consumption value when the pressurization is stopped, and taking the CPU power consumption value when the pressurization is stopped as the optimized CPU power consumption limit value.
When the CPU power consumption limit corresponding to the maximum frequency of the CPU is optimized, it is first detected whether the current heat dissipation parameter value of the CPU is lower than the safe heat dissipation parameter threshold, if so, the CPU power consumption limit is no longer optimized for safety, otherwise, if not, the CPU power consumption limit is continuously tested to obtain the optimal CPU power consumption limit.
Specifically, under the condition that the current heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, the clock frequency of the CPU can be gradually increased by gradually pressurizing the CPU, wherein the power consumption value of the CPU is correspondingly gradually increased in the process of continuously pressurizing the CPU to gradually increase the clock frequency of the CPU, so that the optimal limit value that the power consumption of the CPU can reach is dynamically tested.
It should be noted that the optimal CPU power limit should not exceed the safe power threshold of the CPU based on safety considerations, in addition to being able to support the CPU's turbo to higher frequencies. In view of this, in the process that the clock frequency of the CPU is gradually increased by continuously pressurizing the CPU when the heat dissipation parameter value of the CPU is not lower than the safe heat dissipation parameter threshold, the pressurization is stopped when the clock frequency of the CPU reaches the maximum clock frequency or the power consumption value of the CPU reaches the safe power consumption threshold, and since the power consumption value of the CPU corresponding to the time when the pressurization is stopped can support the CPU to reach the maximum clock frequency or reaches the safe power consumption threshold of the CPU (the CPU operates under the unsafe power consumption condition by continuing the pressurization), the power consumption value of the CPU at this time can be considered as the optimal power consumption limit value of the CPU.
Therefore, the CPU power consumption value at the time of stopping pressurization can be obtained and used as the optimized CPU power consumption limit value, thereby optimizing the CPU power consumption limit value corresponding to the maximum frequency of the CPU. Subsequently, based on the optimized CPU power consumption limit value, the CPU can be supported to reach higher frequency, and the CPU can be operated under the condition of safe power consumption.
When the method is implemented specifically, a corresponding executable file can be embedded in the BOIS code, and the executable file comprises corresponding codes for realizing the functions of all units in the electronic equipment, so that in the power-on self-test process of the electronic equipment, the BIOS can call the executable file to automatically trigger an optimization instruction for indicating the power consumption limit value of the optimized CPU, respond to the instruction to obtain the maximum clock frequency which can be supported by the CPU and the parameter information of the preset safety parameters of the CPU, perform the pressure test on the CPU of the equipment on the basis, and finally obtain the optimal power consumption limit value of the CPU based on the pressure test process, thereby realizing the optimization of the power consumption limit value of the CPU corresponding to the maximum frequency of the Rui of the CPU.
According to the embodiment, the power consumption limit value of the CPU corresponding to the maximum Rui frequency of the CPU is optimized by performing the pressurization test on the CPU in the power-on self-test process of the electronic equipment, and based on the optimized power consumption limit value of the CPU, the Rui frequency of the CPU can be supported to be higher, and the CPU can be operated under the safe power consumption condition.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a sixth embodiment of an electronic device disclosed in the present application, and in the sixth embodiment, the electronic device may further include:
a setting unit 400, configured to set, by the BIOS, the optimized CPU power consumption limit value in a predetermined storage location, so as to replace an original CPU power consumption limit value in the storage location.
Specifically, on the basis of performing a pressurization test on the CPU, obtaining a CPU power consumption value when pressurization is stopped, and taking the CPU power consumption value as an optimized CPU power consumption limit value, the optimized CPU power consumption limit value may be set in a predetermined storage location, for example, may be set in a register corresponding to an MSR of the CPU, so as to replace an original CPU power consumption limit value in the storage location, so that the optimized CPU power consumption limit value becomes effective.
Subsequently, when the CPU core frequency needs to be executed, the optimized CPU power consumption limit value can be read from the storage position, and the core frequency process of the CPU is controlled by utilizing the optimized CPU power consumption limit value. Based on the optimized CPU power consumption limit value, the CPU can be supported to reach higher frequency, and the CPU can be operated under the safe power consumption condition.
