In the related art, the working frequency of the graphics card is adjusted along with the utilization rate, so that the user's requirement cannot be responded in time.
The embodiment of the disclosure provides a control method for a Graphics Processing Unit (GPU), which is characterized in that by collecting power consumption of the GPU, and under the condition that the GPU is in an idle state, responding to the power consumption of the GPU to be increased to be greater than or equal to a first preset power consumption, setting working voltage of the GPU to be a preset maximum working voltage, and setting working frequency of the GPU to be a preset maximum working frequency, a display card can quickly respond to requirements of a user under the condition that the user suddenly uses an operating system when the display card stands by for a long time, so that performance of the display card can be improved, and user experience is optimized.
The following describes in detail a control method of the GPU according to an embodiment of the present disclosure with reference to the accompanying drawings.
Fig. 1 shows a flowchart of a control method of a GPU provided by an embodiment of the present disclosure. In one possible implementation, the execution subject of the control method of the GPU (Graphics Processing Unit, graphics processor) may be a control device of the GPU, for example, the control method of the GPU may be executed by a terminal device or a server or other electronic device. The terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal digital assistant (Personal DigitalAssistant, PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, or the like. In some possible implementations, the control method of the GPU may be implemented by a processor invoking computer readable instructions stored in a memory. As shown in fig. 1, the control method of the GPU includes steps S11 to S12.
In step S11, the power consumption of the GPU is collected.
In step S12, in a case where the GPU is in an idle state, in response to the power consumption of the GPU increasing to be greater than or equal to a first preset power consumption, the operating voltage of the GPU is set to a preset maximum operating voltage, and the operating frequency of the GPU is set to a preset maximum operating frequency.
In the embodiment of the disclosure, the power consumption of the GPU may be read through a preset device. For example, the preset device may be INA3221 or the like, and is not limited herein. In addition, a system management controller (System Management Controller, SMC) in the GPU may periodically read power consumption data of the GPU from the preset device.
In the embodiments of the present disclosure, the power consumption of the GPU may represent the total power consumption of the GPU, which may include the dynamic power consumption of the GPU and the static power consumption of the GPU. For example, the total power consumption P of the GPU total ＝P dynamic +P static . Wherein P is dynamic Representing dynamic power consumption of GPU, P static Representing the static power consumption of the GPU. The static power consumption of the GPU may be a fixed value, and may be measured by an oscilloscope or may be obtained by other means.
In the embodiment of the present disclosure, in the case where the GPU is in an idle state, it may be determined whether the power consumption of the GPU suddenly increases to be greater than or equal to a first preset power consumption. If the power consumption of the GPU is increased to be greater than or equal to the first preset power consumption, the working voltage of the GPU may be set to a preset maximum working voltage, and the working frequency of the GPU may be set to a preset maximum working frequency. When the GPU is in the idle state, if the power consumption of the GPU increases to be greater than or equal to the first preset power consumption, it may be determined that the power consumption of the GPU suddenly increases to be greater. For example, after the graphics card stands by, the user suddenly starts playing a game or watching a video.
In one possible implementation, the method further includes: and setting the GPU to an idle state in response to the operating system entering the idle state.
As one example of this implementation, the operating system may enter the idle state when the idle task is the only task.
In this implementation manner, the GPU may be set to an idle state in response to the operating system entering the idle state, and in response to the power consumption of the GPU increasing to be greater than or equal to the first preset power consumption in the case where the GPU is in the idle state, the operating voltage of the GPU is set to a preset maximum operating voltage, and the operating frequency of the GPU is set to the preset maximum operating frequency, so that the user demand can be responded in time.
In one possible implementation, the method further includes: and setting the GPU to a burst (burst) state in response to the power consumption of the GPU increasing to be greater than or equal to a first preset power consumption under the condition that the GPU is in an idle state. In this implementation, the GPU is set to the burst state in response to the power consumption of the GPU increasing to be greater than or equal to the first preset power consumption in a case where the GPU is in the idle state, and the case where the power consumption increases suddenly is handled in time.
In one possible implementation, the method further includes: and reducing the working voltage and/or the working frequency of the GPU in response to the power consumption of the GPU being greater than or equal to second preset power consumption, wherein the second preset power consumption is greater than the first preset power consumption.
As one example of this implementation, the operating voltage and operating frequency of the GPU may be reduced in response to the power consumption of the GPU being greater than or equal to a second preset power consumption.
As another example of this implementation, the operating voltage of the GPU may be reduced in response to the power consumption of the GPU being greater than or equal to a second preset power consumption.
As another example of this implementation, the operating frequency of the GPU may be reduced in response to the power consumption of the GPU being greater than or equal to a second preset power consumption.
In this implementation manner, the power consumption of the GPU is controlled by adopting a power capping technique (power capping) by reducing the operating voltage and/or the operating frequency of the GPU in response to the power consumption of the GPU being greater than or equal to the second preset power consumption, so that the security of the GPU can be improved.
In one possible implementation, the method further includes: collecting the temperature of the GPU; and reducing the working voltage and/or the working frequency of the GPU in response to the temperature of the GPU being greater than or equal to the preset temperature.
As an example of this implementation, the operating voltage and operating frequency of the GPU may be reduced in response to the temperature of the GPU being greater than or equal to a preset temperature.
As another example of this implementation, the operating voltage of the GPU is reduced in response to the temperature of the GPU being greater than or equal to a preset temperature.
As another example of this implementation, the operating frequency of the GPU is reduced in response to the temperature of the GPU being greater than or equal to a preset temperature.
In the implementation manner, the temperature of the GPU is acquired, and the working voltage and/or the working frequency of the GPU are reduced in response to the fact that the temperature of the GPU is greater than or equal to the preset temperature, so that the temperature of the GPU is controlled by adopting a temperature wall, and the safety of the GPU can be improved.
In one possible implementation manner, after the setting the operating voltage of the GPU to the preset maximum operating voltage and the setting the operating frequency of the GPU to the preset maximum operating frequency, the method further includes: responding to the GPU to maintain the preset maximum working voltage and the preset maximum working frequency for a first preset duration, and acquiring the current turnover rate of the GPU; and adjusting the working voltage and the working frequency of the GPU according to the current turnover rate.
In this implementation manner, the preset maximum operating voltage and the preset maximum operating frequency may be maintained for a first preset period, that is, after the operating voltage of the GPU is set to the preset maximum operating voltage and the operating frequency of the GPU is set to the preset maximum operating frequency, the preset maximum operating voltage and the preset maximum operating frequency may be maintained until the first preset period is reached.
As one example of this implementation, the GPU may be set to a power consumption scene control state in response to a duration in which the GPU maintains the preset maximum operating voltage and the preset maximum operating frequency reaching a first preset duration.
The flip rate may represent the number of times the signal is flipped per unit time. The current roll-over rate of the GPU may represent the current roll-over rate of the GPU.
In this implementation manner, the corresponding relationship of the target voltage frequency corresponding to the GPU currently may be determined according to the current turnover rate, and the target working voltage and the target working frequency of the GPU may be determined according to the corresponding relationship of the target voltage frequency.
In this implementation manner, the current turnover rate of the GPU is obtained by responding to the GPU to maintain the preset maximum working voltage and the preset maximum working frequency for a first preset time, and the working voltage and the working frequency of the GPU are adjusted according to the current turnover rate, so that the voltage frequency corresponding relation suitable for the current scene can be determined based on the current turnover rate of the GPU, and the working voltage and the working frequency suitable for the current scene can be determined, and the performance power consumption ratio of the GPU can be improved.
As an example of this implementation, the obtaining the current roll-over rate of the GPU includes: acquiring current power consumption parameters of the GPU; and determining the current turnover rate of the GPU according to the current power consumption parameter.
In this example, the power consumption parameter of the GPU may be any parameter capable of representing the power consumption of the GPU. In this example, the current roll-over rate of the GPU may be determined from at least one current power consumption parameter of the GPU. For example, the current slew rate of the GPU may be determined from two or more current power consumption parameters of the GPU.
In this example, by acquiring the current power consumption parameter of the GPU and determining the current roll-over rate of the GPU according to the current power consumption parameter, the current roll-over rate of the GPU can be accurately determined.
In one example, the current power consumption parameter includes at least two of: duty cycle, maximum power consumption, current operating frequency, current operating voltage.
In this example, the power consumption of the GPU may be read by a preset device. The preset device may trigger an interrupt in response to the power consumption of the GPU reaching a preset power consumption threshold. In addition, the system management controller in the GPU may periodically read the power consumption data of the GPU from the preset device. Compared with the mode of singly controlling the power consumption of the GPU by the operating system in the related art, the method has the advantages that the GPU participates in the combined control, so that the power consumption optimization of the operating system layer can be obtained, and the power consumption optimization of the GPU layer can be obtained.
The duty cycle of the current scene can be obtained according to the power consumption and the interrupt times of the GPU acquired in the second preset time periodRatio, duty cycle, maximum power consumption, and current power consumption. For example, duty cycle d=t 2 /(t 1 +t 2 ) Duty cycle c=t 1 +t 2 The maximum power consumption can adopt P max Indicating that the current power consumption may employ P current And (3) representing.
In this example, the current operating frequency and/or the current operating voltage may also be obtained. Wherein the current operating frequency may be f current Indicating that the current operating voltage may be v current And (3) representing.
In one example, the current power consumption parameters may include a duty cycle, a maximum power consumption, a current operating frequency, and a current operating voltage.
In this example, by determining the current slew rate of the GPU according to at least two of the duty cycle, the maximum power consumption, the current operating frequency, the current operating voltage, the accuracy of the determined current slew rate can be improved.
In one example, the determining the current roll-over rate of the GPU according to the current power consumption parameter includes: determining a ratio of the maximum power consumption to the current power consumption; and determining the current turnover rate of the GPU according to the duty ratio, the working period, the ratio, the current working frequency and the current working voltage.
Wherein, the ratio R=P of the maximum power consumption to the current power consumption max /P current 。
In this example, by determining a ratio of the maximum power consumption to the current power consumption and determining a current roll-over rate of the GPU according to the duty cycle, the ratio, the current operating frequency, and the current operating voltage, an accurate current roll-over rate can more accurately reflect a current scene of the GPU.
In another example, the determining the current roll-over rate of the GPU according to the current power consumption parameter includes: determining a ratio of the current power consumption to the maximum power consumption; and determining the current turnover rate of the GPU according to the duty ratio, the working period, the ratio, the current working frequency and the current working voltage.
In one example, the determining the current roll-over rate of the GPU according to the current power consumption parameter includes: and inputting the current power consumption parameter into a pre-trained neural network, and outputting the current turnover rate through the neural network.
In this example, by pre-training a neural network for determining a roll-over rate according to a power consumption parameter and inputting the current power consumption parameter into the pre-trained neural network, the current roll-over rate is output via the neural network, whereby the accuracy of the determined current roll-over rate can be improved.
In another example, a polynomial function may be pre-designed and each current power consumption parameter may be input into the preset polynomial function to obtain the current slew rate of the GPU.
In one example, a current inversion rate of the GPU may be obtained at a preset frequency, and a target voltage frequency correspondence currently corresponding to the GPU may be redetermined in response to the current inversion rate being different from the inversion rate obtained last time.
Of course, in other examples, the time for obtaining the current inversion rate of the GPU may be flexibly set according to the application scenario, which is not limited herein.
At the process node before 40nm, the dynamic power consumption of the GPU is a large percentage of the total power consumption. With the evolution of the process, the static power consumption gradually increases in the ratio of the total power consumption to the extent comparable to the dynamic power consumption at 7nm, which further increases the difficulty of implementing DVFS (Dynamic Voltage and Frequency Scaling, dynamic voltage frequency adjustment).
In one example, dynamic power consumption P dynamic ＝α×C×V 2 X F. Wherein alpha is the turnover rate, C is the load capacitance, V is the working voltage, and F is the working frequency. Therefore, by reducing at least one of the slew rate, the load capacitance, the operating voltage, and the operating frequency, the purpose of reducing power consumption can be achieved.
Since the dynamic power consumption is proportional to the square of the operating voltage, the operating voltage is reduced by 30%, and the dynamic power consumption can be reduced by 50%, the voltage reduction is a main means for reducing the power consumption of the GPU. The operating voltage is limited by factors such as the chip process, the switching voltage under the current process conditions, the operating frequency, etc. The chip technology has limitation on the highest voltage and the lowest voltage under a certain technology node, the switching voltage mainly limits the lowest working voltage of the chip, and the working frequency also limits the lowest working voltage of the chip.
The roll-over rate may be application, architecture, design implementation, etc., and the roll-over rate is relatively large with respect to the application. Wherein the application may determine a lower limit of the slew rate and the architecture and design implementation may determine an upper limit of the slew rate. In addition, in the implementation level, the reduction of the slew rate may be implemented by clock gating (clock gating). In some examples, the slew rate may also be referred to as a power factor or a switching coefficient, etc., without limitation herein.
The operating frequency of the GPU is positively correlated to the operating voltage, power consumption, and performance of the GPU. In general, it is desirable to maximize performance and minimize power consumption.
The load capacitance is mainly determined by the chip process. In the chip design stage, it is not generally considered how to actively reduce the load capacitance.
In this implementation manner, at least two voltage frequency correspondence relationships may be preset, and a correspondence relationship between at least two voltage frequency correspondence relationships and a preset slew rate interval may be preset. For example, a plurality of voltage frequency correspondence relationships may be preset. The working voltage corresponding to any working frequency in any voltage frequency corresponding relation can be the minimum working voltage capable of meeting the working frequency; the operating frequency corresponding to any operating voltage in any voltage frequency corresponding relation can be the maximum operating frequency supported by the operating voltage.
After determining the current turnover rate of the GPU, a preset turnover rate interval to which the current turnover rate belongs may be determined, and a voltage frequency corresponding relation corresponding to the preset turnover rate interval to which the current turnover rate belongs may be determined as a target voltage frequency corresponding relation.
As an example of this implementation, a ratio function of the power consumption and the operating frequency of the GPU may be obtained according to the target voltage frequency correspondence and the current roll-over rate; the ratio function is led to work voltage, and target work voltage is determined according to extreme points; and determining a target working frequency according to the corresponding relation between the target working voltage and the target voltage frequency. In this implementation, the power consumption of the GPU may refer to the overall power consumption of the GPU.
For example, the target voltage frequency corresponds to f=f (p, V, t), where F (p, V, t) =c 0 ×p 2 +c 1 ×V 2 +c 2 ×t 2 +c 3 ×p×V+c 4 ×V×t+c 5 ×p×t+c 6 ×p+c 7 ×V+c 8 X t, F represents the operating frequency, V represents the operating voltage, p represents the process angle, t represents the temperature, c 0 To c 8 Is a fitting parameter.
For example, the ratio of the power consumption of the GPU to the operating frequency is P total /F＝α×C×V 2 +P static F. Wherein P is total /F may represent the power consumption required per frequency. The target operating voltage can be determined by deriving the ratio function from V. From f=f (p, V, t), the target operating frequency can be determined.
In this implementation, the target voltage frequency corresponding relation and the current turnover rate are used for obtaining
To the ratio function of the power consumption and the working frequency of the GPU, deriving the ratio function to the working voltage, determining a target working voltage according to a pole 5 value point, and determining according to the corresponding relation between the target working voltage and the target voltage frequency
The target operating frequency, thereby enabling the performance-to-power ratio of the GPU to remain theoretically optimal.
The method for controlling the GPU according to the embodiments of the present disclosure is described below through a specific application scenario.
In this implementation, the GPU may be set to an idle state in response to the operating system entering the idle state.
