Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The embodiment of the application provides a method for adjusting a processor frequency, and an execution body of the method for adjusting a processor frequency may be an adjusting device for the processor frequency provided in the embodiment of the application, or an electronic device integrated with the adjusting device for the processor frequency, where the adjusting device for the processor frequency may be implemented in a hardware or software manner. The electronic device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
For example, taking the execution body of the method for adjusting the processor frequency as an electronic device as an example, as shown in fig. 1, the electronic device may determine a key thread corresponding to a current scene at the beginning of frame drawing, where frame drawing is simply referred to as a frame drawing period, and represents a process of drawing a certain frame picture, and specifically, the frame drawing period refers to a display interval of two adjacent frames. The key thread is a thread (for example, may be T1 (ux), T2 (ux)..tn (ux)) for determining a frame drawing duration within a frame time when frame drawing occurs, and the threads other than the key thread are non-key threads (for example, may be T1, T2..tn), then, in a frame drawing process of a preset number in the past, a thread with the longest running time per frame average in the key thread is selected as a target thread, and the running time per frame average in the target thread is taken as a target frame drawing load, and then, a frequency lower limit of the current processor is adjusted according to the target frame drawing load. In this way, the thread with the longest running time of each frame in average in all key threads is selected, the running time of each frame in average in the thread is used as a target frame drawing load, and then the frequency lower limit of the current processor is dynamically adjusted based on the target frame drawing load, so that when the frequency of the processor is adjusted, the frequency adjustment can be more targeted based on the scene and the demand of the key load in the scene on calculation force, and the problems of frame loss and clamping caused by the fact that the frequency of the processor is too low in the scene with the running of the key threads are avoided.
The following detailed description is given below, and the numbers of the following embodiments are not intended to limit the preferred order of the embodiments.
Referring to fig. 2, fig. 2 is a first flowchart of a method for adjusting processor frequency according to an embodiment of the present disclosure. The specific flow of the method for adjusting the processor frequency provided in the embodiment of the present application may be as follows:
101. and determining a key thread corresponding to the current scene when frame drawing starts, wherein the key thread is a thread for determining the frame drawing length within one frame time of frame drawing.
In the prior art, in Linux kernel (an open source computer operating system kernel) used in an Android (Android) system, a processor frequency regulator is generally used to regulate the frequency of a processor. One of the frequency regulators (SchedUtil Governor) based on the utilization rate is a frequency regulator which is currently used more, and the frequency regulator is based on information such as the utilization rate obtained by statistics of a Linux kernel scheduler and the like as a basis for carrying out CPU frequency adjustment. However, if the utilization rate counted by the scheduler and the critical thread of the current scenario are not strongly correlated, the frequency regulator may select a relatively high processor frequency, and the critical thread benefits from the frequency regulator very little, so that the problem of blocking and frame loss occurs in the process of using the electronic device by the user, and power consumption is lost, so that the cruising performance of the electronic device is affected.
Furthermore, since the scheduler's utilization statistics algorithm, e.g., WALT (Window Assisted Load Tracking ), is subject to predicting future characteristics based on the past, there must be some hysteresis in its statistical utilization with respect to changes in the actual processor load. In an application scenario like a game such a periodic drawing, the processor frequency is sometimes staggered from the processor load variation by one cycle: when the key thread is executed, the processor is at a relatively low frequency point, and when the key thread is asleep, the processor is at a relatively high frequency point, so that the problems of blocking and frame loss can be caused in the process of using the electronic equipment by a user.
In the embodiment of the application, the key thread in the periodically drawn scene like a game is identified, and the key thread is used as the access point, so that the problems are avoided. For example, in a scenario where users of games, multimedia video playback, and the like are concerned with fluency, a key thread associated with frame drawing is identified.
For example, where the application is a game, the scene may include lobby waiting, resource loading, grassland running, wild, driving, etc.
It should be noted that a critical thread is a set of threads that plays an important role in the frame drawing period and determines how long the drawing time is this time (i.e., the screen refresh rate of the current interface). In general, the thread that ends running last in the frame drawing period determines the length of this drawing time. The critical threads in the same scenario are typically some specific threads, such as UI (user interface) threads, render threads, engine threads, etc. The critical threads in different scenarios may vary.
102. And in the frame drawing process of the preset number in the past, selecting the thread with the longest running time of each frame in the average of the key threads as a target thread, and taking the running time of each frame of the average of the target thread as a target frame drawing load.
Wherein, the frame drawing process refers to a drawing process of one frame. The critical thread runs on the processor during one frame drawing cycle, loading the frame drawing.
Specifically, the key threads comprise a plurality of types of key threads, average running time per frame of the key threads of different types is calculated respectively in the past preset number of frame drawing processes, and then the average running time per frame of the key threads of the type with the longest average running time per frame is selected as a target frame drawing load.
103. And adjusting the frequency lower limit of the current processor according to the target frame drawing load.
The lower frequency limit of the processor is a default value, and is generally a factory default value. The processor (CPU, central processing unit) frequency, that is, the clock frequency of the processor, is the frequency of operation during processor operation, in Hz, and the processor frequency determines the operating speed of the computer.
In the embodiment of the application, because the critical threads exist in the current scene, the default value of the frequency lower limit is usually lower, and the normal running requirement of the critical threads in the current scene cannot be met, the frequency value of the processor which can meet the normal running of the threads with larger current load is taken as the frequency lower limit of the current processor, and thus the problems of frame loss and clamping can be reduced.
In particular, the present application is not limited by the order of execution of the steps described, and certain steps may be performed in other orders or concurrently without conflict.
As can be seen from the above, in the method for adjusting the processor frequency provided in the embodiment of the present application, the key thread corresponding to the current scene is determined at the beginning of frame drawing, where the key thread is a thread that determines the frame drawing duration within a frame time when frame drawing occurs, then, in a past preset number of frame drawing processes, a thread with the longest running time per frame average in the key thread is selected as a target thread, and the running time per frame average in the target thread is taken as a target frame drawing load, and then, the frequency lower limit of the current processor is adjusted according to the target frame drawing load. According to the scheme, the lower frequency limit of the current processor is dynamically adjusted based on the target frame drawing load, so that when the frequency of the processor is adjusted, the frequency adjustment can be more targeted based on the scene and the demand of key load in the scene on calculation force, and therefore the problems of frame loss and clamping caused by the fact that the frequency of the processor is too low in the scene with key thread operation are avoided.
The method described in the previous examples is described in further detail below by way of example.
Referring to fig. 3, fig. 3 is a second flowchart illustrating a method for adjusting a processor frequency according to an embodiment of the present disclosure. The method comprises the following steps:
201. and determining a key thread corresponding to the current scene when frame drawing starts, wherein the key thread is a thread for determining the frame drawing length within one frame time of frame drawing.
For example, by testing various types of scenes under an application related to frame drawing, recording and marking corresponding key threads in different types of scenes, the key threads in a certain type of scene can be directly determined by the marking when the key threads are identified. Wherein the application related to frame drawing may be a game application.
202. And in the frame drawing process of the preset number in the past, selecting the thread with the longest running time of each frame in the average of the key threads as a target thread, and taking the running time of each frame of the average of the target thread as a target frame drawing load.
For example, the preset number may be 10, in the past 10 frame drawing processes, there are a class a critical thread, a class B critical thread and a class C critical thread in the current scene to participate in running, and the average time of running each frame of the class a critical thread in the past 10 frame drawing processes is T1, the class B critical thread, the average time of running each frame in the past 10 frame drawing processes is T2, the average time of running each frame of the class C critical thread in the past 10 frame drawing processes is T3, where T3 is the largest, and then T3 is taken as the target frame drawing load.
203. And acquiring the average running time of each frame of the key thread in the past preset number of frame drawing processes, the average frequency of a processor during each frame drawing and the target frame rate of the current scene, wherein the target frame rate is a preset fixed value.
For example, the preset number may be 10 times, during the past 10 frame drawing processes, there are a class a critical thread, a class B critical thread and a class C critical thread in the current scene to participate in running, that is, the time that the three types of critical threads run per frame is calculated in the past 10 drawing processes, and the average frequency of the processor in the 10 drawing processes is calculated.
In one embodiment, the process of obtaining the target frame rate of the current scene in the plurality of preset fixed values 203 may include:
the frame rate in the current scene is obtained.
And selecting a preset fixed value closest to the frame rate as a target frame rate, wherein the target frame rate is not smaller than the frame rate.
The target frame rate is a preset fixed value of the current scene, and is generally 30FPS, 45FPS, 60FPS, 90FPS, 120FPS, and 144FPS.
When judging the target frame rate of the current scene, the corresponding judgment can be made according to the following table:
| frame rate in current scene | Preset fixed value of target frame rate |
| <＝30FPS | 30FPS |
| <＝45FPS | 45FPS |
| <＝60FPS | 60FPS |
| <＝90FPS | 90FPS |
| <＝120FPS | 120FPS |
| <＝144FPS | 144FPS |
For example, if the frame rate in the current scene is 55FPS, which value 55FPS < =60 FPS, the target frame rate in the current scene is determined to be 60FPS. In practice, the target frame rate is the frame rate that makes the current scene not lose frames, and the target frame rate can be set manually, or can be changed automatically by a corresponding program according to the change of the current scene.
204. And obtaining a first target frequency according to the average running time of each frame of the key thread, the average frequency of the processor when each frame is drawn, the target frame rate of the current scene and the target frame drawing load.
The estimation method of the lowest frequency satisfying the target frame rate is as follows:
in the frame drawing process of the preset number in the past, the average running time of each frame of the key thread is Array (RunningAvgMs), the average frequency of the processor in each frame drawing is FreqAvg, the target frame drawing load is KeyRunningAvgMs, the target frame rate is FpsTarget, the drawing time of each frame corresponding to the target frame rate is TagetRenningMs=1000/FpsTarget, the first target frequency is Freq, and then the first target frequency Freq meeting the target frame rate FpsTarget is:
Freq＝KeyRunningAvgMs*FreqAvg/TargetRunningMs
205. the lower frequency limit of the current processor is adjusted to a first target frequency.
I.e. updating the lower frequency limit of the current processor to the first target frequency obtained above.
In one embodiment, the method for adjusting the frequency of the processor may further include:
and associating the current scene with a first target frequency corresponding to the current scene and uploading the first target frequency to the cloud.
For example, where the application is a game, the scene may include lobby waiting, resource loading, grassland running, wild, driving, etc.
For example, a specific scene in an application related to frame drawing can be marked in a test environment, different types of scenes are distinguished, first target frequencies in the different types of scenes are calculated respectively, and the scene type and the first target frequency corresponding to the scene type are sent to a cloud as default first target frequencies of specific application scenes of an electronic device side.
In one embodiment, the method for adjusting the frequency of the processor may further include:
when the frequency of a processor of a current scene is adjusted, a first target frequency corresponding to the current scene is obtained from a cloud;
the lower limit frequency of the processor is adjusted according to the first target frequency.
For example, when the electronic device is in a certain type of scene, the first target frequency corresponding to the type of scene can be directly obtained from the cloud, so that the waiting time of the electronic device for collecting enough effective data can be reduced, and the frequency adjustment efficiency of the processor in the scheme is improved.
It will be appreciated that the first target frequency may be dynamically varied according to the frame drawing load of the critical thread over a period of time.
In one embodiment, the key thread types of different scenes in the application related to frame drawing also change, and the application related to frame drawing can send a scene change notification message to a scheduler through an operating system, and the adjustment mechanism of the processor frequency in the scheme is triggered in time to dynamically adjust the lower limit of the processor frequency of the current scene.
206. And after the frame drawing is finished, the lower frequency limit of the current processor is restored to a default value.
After the frame drawing is finished, no key thread participates in the operation in the current scene, and the demand on calculation force is smaller at the moment, so that the lower frequency limit is restored to a default value, and the power consumption can be saved.
In one embodiment, the threads other than the critical threads are non-critical threads, and after the process of restoring the lower frequency limit of the current processor to the default value in 206, the method may further include:
wherein the runtime of the non-critical thread on the processor is a frame rendering independent load during one frame rendering period.
Specifically, after frame drawing is finished, the average running time of each frame of non-critical threads in the past preset number of frame drawing processes is obtained as the frame drawing irrelevant load of the current scene, then, based on the frame drawing irrelevant load of the current scene, the second target frequency is determined according to the frequency regulator, and then, the lower frequency limit is adjusted to the second target frequency from a default value. The adjustment of the processor frequency in accordance with the frequency adjustor is prior art and will not be described in detail here.
As can be seen from the above, in the method for adjusting the processor frequency according to the embodiment of the present application, the key thread corresponding to the current scene is determined when frame drawing starts, where the key thread is a thread that determines the frame drawing length within a frame time when frame drawing occurs, then, in a frame drawing process of a preset number in the past, a thread with the longest running time of each frame in average among the key threads is selected as a target thread, the running time of each frame in average of the target thread is taken as a target frame drawing load, and then, the frequency lower limit of the current processor is adjusted according to the target frame drawing load. In the prior art, when the frequency of the processor is adjusted, the frequency scheduler is staggered with the load change of the processor by one period, so that the problem of low frequency of the processor when key threads are executed is caused, and therefore, the problem of frame loss and blocking is caused. According to the scheme, the frequency curve of the processor and the actual load curve are overlapped as much as possible, the problem of blocking caused by load and frequency hysteresis is reduced, and the running fluency of the electronic equipment is improved.
Referring to fig. 4, fig. 4 is a third flowchart of a method for adjusting a processor frequency according to an embodiment of the present disclosure. The method comprises the following steps:
301, determining a key thread corresponding to a current scene when frame drawing starts, wherein the key thread is a thread for determining the frame drawing length within one frame time when frame drawing occurs.
For example, by testing various types of scenes under the application of the frame drawing class, a thread which can determine the drawing length of the frame within the frame time when drawing occurs is recorded, the thread is marked as a key thread, and the thread can be determined by the mark when the key thread is identified.
For example, at the beginning of frame drawing, it is identified that the critical threads in the current scenario include class A threads, class B threads, and class C threads.
302, selecting a thread with the longest running time of each frame in average among key threads as a target thread in the frame drawing process of the preset number in the past, and taking the running time of each frame in average of the target thread as a target frame drawing load.
For example, the preset number may take a value of 3 times, and before the frame, the electronic device obtains the average running time of each frame of the class a thread, the class B thread and the class C thread in the past 3 frame drawing processes to be 10ms, 12ms and 8ms respectively, where the running time of the class B thread is the longest, i.e. 12ms is used as the target frame drawing load.
303, acquiring the average running time per frame of the key thread in the process of drawing the past preset number of frames, the average frequency of a processor during drawing each frame and the target frame rate of the current scene, wherein the target frame rate is a preset fixed value.
For example, following the example in flow 302, the time of average run of critical threads during the last 3 frame draws is obtained, namely: (10ms+12ms+8ms)/3=10ms.
For example, the processor frequency is 2.0GHZ during the first frame drawing, 1.5GHZ during the second frame drawing, and 2.5GHZ during the third frame drawing, and the average frequency of the processor per frame drawing is (2.0 ghz+1.5ghz+2.5 GHZ)/3=2 GHZ.
For example, if the frame rate in the current scene is 55FPS, which value 55FPS < =60 FPS, the target frame rate in the current scene is determined to be 60FPS.
304. And obtaining a first target frequency according to the average running time of each frame of the key thread, the average frequency of the processor when each frame is drawn, the target frame rate of the current scene and the target frame drawing load.
The method for estimating the lowest frequency satisfying the target frame rate is as follows:
in the frame drawing process of the preset number in the past, the average running time of each frame of the key thread is Array (RunningAvgMs), the average frequency of the processor in each frame drawing is FreqAvg, the target frame drawing load is KeyRunningAvgMs, the target frame rate is FpsTarget, the drawing time of each frame corresponding to the target frame rate is TagetRenningMs=1000/FpsTarget, the first target frequency is Freq, and then the first target frequency Freq meeting the target frame rate FpsTarget is:
Freq＝KeyRunningAvgMs*FreqAvg/TargetRunningMs
For example, the values in the above examples are put into the formula calculation: freq=12×2/(1000/60) =1.44 GHZ, i.e., 1.44GHZ is the first target frequency.
305. And acquiring the data information of the running time of the key thread in the frame drawing process under the frequency of different processors in the current scene.
Due to the influence of hardware software or physical factors in practical situations, for example, the time for drawing a frame in an ideal state is 50ms when the D-thread is at the frequency of a 100MZ processor, but in practical situations, the time for drawing a frame in the frequency of the 100MZ processor can be longer than in an ideal state, for example, can be 60ms. Therefore, it is necessary to test the data information of the key thread in the drawing process under the frequency of different processors and make statistics to obtain a compensation value, i.e. a correction value.
306. A correction value of the first target frequency is calculated based on the data information.
For example, at a processor frequency of 2.0GHZ, the critical thread E ideally draws a frame for 2.5ms, and at a processor frequency of 2.0GHZ, the critical thread actually draws a frame for 3ms, and the correction value is 3/2.5=1.2.
It should be noted that, here, only the general idea of calculating the correction value is exemplified, more data information is obtained in the actual calculation process, and fitting is performed according to the performances of different scenes to obtain the correction value. In theory, the correction values corresponding to different scenes are fixed, the correction values corresponding to different scenes can be tested respectively and used as correction default values of the corresponding scenes, and the correction default values are directly called according to the scenes when the correction default values are needed to be used. Wherein the correction value is a constant greater than 1.
307. And performing correction processing on the first target frequency based on the correction value.
The corrected first target frequency Freq satisfying the target frame rate FpsTarget is:
Freq＝C*KeyRunningAvgMs*FreqAvg/TargetRunningMs
for example, if the correction value c=2 for the current scene is recorded as C, then the example in the flow 304 brings the correction value c=2 into the above formula for calculation: freq=1.3x12×2/(1000/60) = 1.872GHZ, i.e., 1.872GHZ is used as the first target frequency after correction processing.
308. And adjusting the lower frequency limit of the current processor to the first target frequency after correction processing.
For example, if the default value of the lower frequency limit of the current processor is 500MHZ, the lower frequency limit of the current processor is updated from 500MHZ to 1.872GHZ.
309. And after the frame drawing is finished, the lower frequency limit of the current processor is restored to a default value.
For example, if the default value of the lower frequency limit of the current processor is 500MHZ, the lower frequency limit of the current processor is restored to 500MHZ from 1.872GHZ.
As can be seen from the above, in the method for adjusting the processor frequency according to the embodiment of the present application, the key thread corresponding to the current scene is determined when frame drawing starts, where the key thread is a thread that determines the frame drawing length within a frame time when frame drawing occurs, then, in a frame drawing process of a preset number in the past, a thread with the longest running time of each frame in average among the key threads is selected as a target thread, the running time of each frame in average of the target thread is taken as a target frame drawing load, and then, the frequency lower limit of the current processor is adjusted according to the target frame drawing load. According to the scheme, the lower frequency limit of the current processor is dynamically adjusted based on the target frame drawing load, so that when the frequency of the processor is adjusted, the frequency adjustment can be more targeted based on the scene and the demand of key load in the scene on calculation force, and therefore the problems of frame loss and clamping caused by the fact that the frequency of the processor is too low in the scene with key thread operation are avoided.
