[0028] Figure 1 It is a schematic flowchart of the background process control method provided by the embodiments of the present application. The background process control method may include:
[0029] Step 101: Obtain the influencing factor corresponding to the first background process;
[0030] In some possible implementations of the embodiments of the present application, the first background process in the embodiments of the present application is any one of multiple background processes; the influencing factor in the embodiments of the present application is used to determine the probability of an exception occurring in the background process, and the influencing factor includes, but is not limited to: the duration of the process occupying a high CPU resource, the process priority, whether the process occupies an audio resource, whether the process turns on the camera, whether the process is a charging process, whether the process is a system critical process, etc., whether the application program corresponding to the process is a preset type of application program, the occupancy rate of the process occupying the CPU resource, and so on.
[0031] Step 102: Determine the probability of an exception in the first background process according to the influencing factor corresponding to the first background process;
[0032] In some possible implementations of the embodiments of the present application, assuming the probability of a process having an exception is P, then the probability of the process not having an exception is 1 - P. Based on the principle of logistic regression transformation, the relationship between the probability of a process having an exception and the influencing factors corresponding to the process is as shown in the following formula (1):
[0033]
[0034] Wherein, in formula (1), P is the probability of the process having an exception, x i is the influencing factor numbered i, β i is the factor coefficient of the influencing factor numbered i, and i is a positive integer less than or equal to n, where n is the number of influencing factors corresponding to the process.
[0035] After obtaining the influencing factors corresponding to the first background process, substituting the obtained influencing factors into the above formula (1) can obtain the probability of the first background process having an exception.
[0036] In some possible implementations of the embodiments of the present application, before step 102, the background process control method provided by the embodiments of the present application may further include: using a logistic regression algorithm to determine the factor coefficient of the influencing factors corresponding to the first background process; correspondingly, step 102 may include: determining the probability of the first background process having an exception according to the influencing factors and the factor coefficient.
[0037] In some possible implementations of the embodiments of the present application, when using a logistic regression algorithm to determine the factor coefficient of the influencing factors corresponding to the first background process, multiple background processes may be statistically analyzed in advance, and the influencing factors and exception statuses of the multiple background processes may be statistically analyzed. Exemplarily, the statistical results are shown in Table 1 below:
[0038] Table 1
[0039]
[0040] Among them, Table 1 shows five influencing factors of a process, and the five influencing factors are process priority, whether the process occupies audio resources, whether the process is a charging process, the CPU resources occupied by the process, and whether the camera of the process is turned on. When the value corresponding to whether the process occupies audio resources is 1, it means the process occupies audio resources; when the value corresponding to whether the process occupies audio resources is 0, it means the process does not occupy audio resources; when the value corresponding to whether the process is a charging process is 1, it means the process is not a charging process; when the value corresponding to whether the process is a charging process is 0, it means the process is a charging process; when the value corresponding to whether the camera of the process is turned on is 1, it means the camera of the process is turned on; when the value corresponding to whether the camera of the process is turned on is 0, it means the camera of the process is not turned on. When the value corresponding to the abnormal state of the process is 1, it means the process is an abnormal process, that is, the process has an abnormality; when the value corresponding to the abnormal state of the process is 0, it means the process is a non-abnormal process, that is, the process has no abnormality. Among them, after controlling a certain process, if the application program corresponding to the process has an abnormality, for example, foreground jamming or audio frame loss, it is determined that the process is an abnormal process, otherwise it is a non-abnormal process.
[0041] Based on each influencing factor in Table 1 above, through the logistic regression algorithm, the factor coefficients of each influencing factor can be obtained.
[0042] In some possible implementations of the embodiments of the present application, the function model of the logistic regression algorithm is the sigmoid function. Based on the sigmoid function, the above formula (1) is transformed into the matrix form shown in the following formula (2):
[0043]
[0044] In formula (2), X is the matrix of influencing factors (x1, x2, ……, x n ).
[0045] The cross entropy is selected as the loss function of the logistic regression, and the loss function of the logistic regression is shown in the following formula (3):
[0046]
[0047] Among them, in formula (3), m is the total number of data in Table 1 above, y( i ) is the abnormal state value of the process corresponding to the i-th piece of data, and h β (x (i) ) is the value obtained by substituting the values of the influencing factors and the factor coefficients in the i-th piece of data into the sigmoid function.
[0048] The essence of the regression operation is to obtain the minimum value of the loss function shown in formula (3). In some possible implementations of the embodiments of the present application, the gradient descent method can be used to calculate the minimum value of the loss function shown in formula (3), and the factor coefficient of each influencing factor can be obtained. Among them, the factor coefficient of the jth influencing factor is shown in the following formula (4):
[0049] β jk =β jk-1 +η(y (i) -h β (x (i) ))x j (4)
[0050] Among them, in formula (4), β jk is the factor coefficient of the jth influencing factor x j obtained in the kth iteration, β jk-1 is the factor coefficient of the jth influencing factor obtained in the (k - 1)th iteration, η is the learning rate, and the value of η can be 0.01.
[0051] In some possible implementations of the embodiments of the present application, the number of iterations can be preset. For example, the number of iterations is 1000 times. After looping the above formula (4) 1000 times, the factor coefficient of the jth influencing factor x j can be obtained.
[0052] After obtaining the influencing factors corresponding to a certain background process and calculating the factor coefficients of each influencing factor, the probability of the background process being abnormal can be obtained through the above formula (1).
[0053] Step 103: Determine the first duration according to the probability of the first background process being abnormal; the first duration is the duration for which the first background process occupies the central processor resources;
[0054] In some possible implementations of the embodiments of the present application, the duration of occupying the central processor resources corresponding to different probabilities can be set by configuring the fair group plan (CONFIG_FAIR_GROUP_SCHED, CFS) bandwidth control (Bandwidth Control). CFS Bandwidth Control can set an upper limit on the duration for which a process group can occupy the central processor resources.
[0055] In some possible implementations of the embodiments of the present application, the higher the probability of a process being abnormal, the lower the upper limit of the duration for which the process occupies the central processor resources can be.
[0056] Exemplarily, the correspondence between the probability of a process being abnormal and the duration of occupying the central processor resources is shown in Table 2 below:
[0057] Table 2
[0058] Probability of process exception Occupation duration of central processor resources (unit: second) 60％ 120 70％ 90 80％ 60 90％ 30
[0059] Assume that the probability of an exception occurring in the first background process is determined to be 60% through step 102, then the first duration is determined to be 120 seconds according to Table 2 above.
[0060] Step 104: Control the first background process according to the first duration.
[0061] In some possible implementations of the embodiments of the present application, in step 104, it is possible to control the duration of the first background process occupying the central processing unit (CPU) resources not to exceed the first duration. When the duration of the first background process occupying the CPU resources reaches the first duration, CPU resources may not be allocated to the first background process.
[0062] In the embodiments of the present application, by obtaining the influencing factor corresponding to the first background process; determining the probability of an exception occurring in the first background process according to the influencing factor corresponding to the first background process; determining the first duration according to the probability of an exception occurring in the first background process; the first duration is the duration of the first background process occupying the CPU resources; controlling the first background process according to the first duration. In this way, it is possible to determine the duration of the background process occupying the CPU resources based on the influencing factor corresponding to the background process, and control the background process through this duration, rather than directly killing the background process, which can avoid abnormal operation of the application program corresponding to the background process.
[0063] In some possible implementations of the embodiments of the present application, when determining the first duration, the temperature of the CPU may also be considered. Based on this, step 103 may include: determining the first duration according to the probability of an exception occurring in the first background process and the temperature of the CPU.
[0064] In some possible implementations of the embodiments of the present application, the higher the probability of an exception occurring in the process, the higher the temperature of the CPU, and the lower the upper limit of the duration of the process occupying the CPU resources may be.
[0065] Exemplarily, the corresponding relationship between the probability of an exception occurring in the process, the CPU temperature, and the duration of occupying the CPU resources is shown in Table 3 below:
[0066] Table 3
[0067]
[0068] Assume that through step 102, it is determined that the probability of the first background process being abnormal is 60%, and when the temperature of the central processing unit is 20 degrees, according to Table 3 above, the first duration is determined to be 160 seconds, and then the duration for the first background process to occupy the central processing unit resources is controlled not to exceed 160 seconds; when the duration for the first background process to occupy the central processing unit resources reaches 160 seconds, the central processing unit resources may not be allocated to the first background process.
[0069] In the embodiments of the present application, the duration for the background process to occupy the central processing unit resources can be determined based on the probability of the background process being abnormal and the temperature of the central processing unit, and the background process is controlled by this duration, rather than directly killing the background process, which can avoid abnormal operation of the application program corresponding to the background process.
[0070] In some possible implementations of the embodiments of the present application, after step 104, the background process control method provided by the embodiments of the present application may further include: when an exception occurs in the application program corresponding to the first background process, releasing the control of the first background process.
[0071] Exemplarily, assume that the first duration determined through step 103 is 120 seconds; when the duration for the first background process to occupy the central processing unit resources reaches 120 seconds, the central processing unit resources are not allocated to the first background process. After the central processing unit resources are not allocated to the first background process, an exception occurs in the application program corresponding to the first background process. For example, the application program corresponding to the first background process has a frozen interface or audio frame loss, then the control of the first background process is released. After the control of the first background process is released, the central processing unit resources will always be allocated to the first background process.
[0072] In the embodiments of the present application, when an exception occurs in the application program corresponding to the background process, by releasing the control of the background process, the normal operation of the application program corresponding to the background process can be ensured.
[0073] In some possible implementations of the embodiments of the present application, after step 104, the background process control method provided by the embodiments of the present application may further include: when an exception occurs in the application program corresponding to the first background process, determining the time for determining the probability of the first background process being abnormal next time.
[0074] Exemplarily, assume that the first duration determined through step 103 is 120 seconds; when the duration for which the first background process occupies the central processing unit (CPU) resources reaches 120 seconds, no CPU resources are allocated to the first background process. After no CPU resources are allocated to the first background process, the application corresponding to the first background process encounters an exception. For example, the application corresponding to the first background process experiences interface jank or audio frame drops. The time for determining the probability of the first background process being abnormal next time is determined to be 24 hours later, that is, the first background process is not controlled within 24 hours. After 24 hours, the probability of the first background process having an abnormality is determined again.
[0075] In the embodiments of the present application, when an application corresponding to a background process encounters an exception, by determining the time for determining the probability of the first background process having an abnormality next time, the number of times of determining the probability of the first background process having an abnormality can be reduced, thereby reducing the occupation of system resources.
[0076] In some possible implementations of the embodiments of the present application, the first background process in the embodiments of the present application may be a background process among multiple background processes whose occupancy rate of CPU resources is greater than an occupancy rate threshold. Correspondingly, step 101 may include: when the occupancy rate of the first background process occupying the CPU resources is greater than the occupancy rate threshold, obtaining the influencing factor corresponding to the first background process.
[0077] Exemplarily, assume that the occupancy rate threshold is 25%. When the occupancy rate of the first background process occupying the CPU resources is greater than 25%, obtain the influencing factor corresponding to the first background process, and then determine the probability of the first background process having an abnormality based on this influencing factor. Next, determine the first duration for which the first background process occupies the CPU resources according to the probability of the first background process having an abnormality, and control the first background process based on this first duration. If the occupancy rate of the first background process occupying the CPU resources is less than or equal to 25%, then the first background process is not controlled, that is, the duration for which the first background process occupies the CPU resources is not controlled.
[0078] In some possible implementations of the embodiments of the present application, the background process control method provided in the embodiments of the present application may further include: when an application corresponding to the first background process encounters an exception, increasing the occupancy rate threshold.
[0079] Exemplarily, it is assumed that the occupancy rate of the central processing unit resources by the first background process is obtained as 30%, and this occupancy rate is greater than the occupancy rate threshold of 25%. Then, the impact factor corresponding to the first background process is obtained, and further, through step 102, the probability that the first background process is abnormal is determined to be 60%. Through step 103, the first duration is determined to be 120 seconds, and the duration for the first background process to occupy the central processing unit resources is controlled not to exceed 120 seconds. When the duration for the first background process to occupy the central processing unit resources reaches 120 seconds, no central processing unit resources are allocated to the first background process. After no central processing unit resources are allocated to the first background process, the application program corresponding to the first background process has an abnormality. For example, the application program corresponding to the first background process has a frozen interface or audio frame drop, then the occupancy rate threshold is increased from 25% to 30%.
[0080] When the occupancy rate of the central processing unit resources by the first background process is greater than 30%, the probability that the first background process is abnormal is determined, and then the duration for the first background process to occupy the central processing unit resources is determined according to the probability that the first background process is abnormal, and then the duration for the first background process to occupy the central processing unit resources is controlled based on this duration. If the occupancy rate of the central processing unit resources by the first background process is less than or equal to 30%, the duration for the first background process to occupy the central processing unit resources is not controlled.
[0081] In the embodiment of the present application, when an abnormality occurs in the application program corresponding to the background process, by increasing the occupancy rate threshold, the number of times of determining the probability that the first background process is abnormal can be reduced, and thus the occupancy of system resources can be reduced.
[0082] Figure 2 It is a schematic flowchart of the process for controlling the duration of the background process provided by the embodiment of the present application. The process for controlling the duration of the background process may include the following steps:
[0083] Step 201: Obtain the occupancy rate of the central processing unit resources by the first background process among multiple background processes;
[0084] Step 202: Determine whether the occupancy rate is greater than the occupancy rate threshold;
[0085] If yes, execute step 203; if no, end;
[0086] Step 203: Obtain the impact factor corresponding to the first background process and the statistical result obtained based on the statistical analysis of the impact factors and abnormal states of multiple background processes, and use the logistic regression algorithm to determine the factor coefficient corresponding to each impact factor;
[0087] Step 204: Determine the probability that the first background process is abnormal according to the impact factor corresponding to the first background process and the factor coefficient corresponding to each impact factor;
[0088] Step 205: Determine a first duration of the central processing unit resources occupied by the first background process according to the probability of an exception occurring in the first background process.
[0089] Step 206: Control the first background process according to the first duration.
[0090] Step 207: Determine whether an exception occurs in the application program corresponding to the first background process.
[0091] If yes, execute Step 207; if no, end.
[0092] Step 208: Increase the occupancy threshold, release the control of the first background process, and determine the time for determining the probability of an exception occurring in the first background process next time.
[0093] Wherein, when the time for determining the probability of an exception occurring in the first background process next time arrives, continue to execute Step 201.
