The method for determining a cause of a freeze provided by an embodiment of the present disclosure can be applied to a terminal installed with an Android system. FIG. 2-1 is a flowchart of a method for determining a cause of a freeze provided by an exemplary embodiment of the present disclosure, as shown in FIG. 2- 1, the method includes:

Step 201: Divide n buffers in the system of the terminal, where the n buffers are used to store the usage records of m types of system resources, where n≥1 and m≥1.

In practical applications, n buffers can be divided in the linux kernel of the Android system, and the n buffers can store the usage records of m kinds of system resources, wherein each buffer is used to store the usage records of at least one system resource. .

Optionally, each buffer can be used to store a usage record of a system resource, and a usage record of a system resource is stored in a separate buffer, which is convenient for the classification of the usage record of the system resource, and is used for later retrieval from the buffer. It is convenient to extract usage records of corresponding kinds of system resources.

Optionally, the m types of system resources may include at least one of memory resources, CPU resources, and I/O bandwidth resources.

It should be noted that the storage space occupied by each buffer is fixed, and optionally, the storage space occupied by each buffer may be 8 kilobytes (English: Kilobyte; KB for short).

Step 202: Update the contents in the n buffers according to the latest usage records of the m types of system resources.

Optionally, according to the latest usage records of m types of system resources, the method for updating the content in the n buffers, as shown in Figure 2-2, may include:

Step 2021: Acquire the latest usage record of the first system resource, where the first system resource is any one of the m types of system resources.

Optionally, the method for obtaining the latest usage record of the first system resource may include:

S11. When monitoring that the first system resource is being used, determine whether the first system resource is a system resource corresponding to the target application running in the foreground.

In the embodiment of the present disclosure, the target application is a preset application that needs the memory to record the usage record of the system resource. Optionally, the target application can be any application running in the foreground. For example, if the user is currently using Michat on the display screen of the terminal, then Michat is a target application, and it is necessary to determine whether the first system resource is Michat. The corresponding system resources, that is, the system resources used to determine whether the first system resource is occupied by Mi Chat; or, the target application can be a specified application running in the foreground, for example, the specified application includes Mi Chat, Xiaomi Desktop and Xiaomi Video, When Mi Chat is running in the foreground, then Mi Chat is a target application, and it is necessary to determine whether the first system resource is the system resource occupied by Mi Chat.

S12. When the first system resource is the system resource corresponding to the target application, acquire the latest usage record of the first system resource.

Step 2022: Delete the earliest usage record of the first system resource in the first buffer for storing the usage record of the first system resource.

Optionally, a first resource linked list may be used in the first buffer to store usage records of the first system resources, and the usage records of the first system resources in the first resource linked list are arranged in chronological order.

Optionally, it is assumed that each buffer stores a usage record of a system resource, the buffer for storing the usage record of memory resources is defined as buffer1, the buffer for storing the usage record of CPU resources is buffer2, and the buffer for storing I/O bandwidth resources is defined. The buffer used for the record is buffer3. The data structure of buffer1 can be shown in Figure 2-3a. Buffer1 records the first timestamp t1 when memory allocation is requested, the process identifier pid corresponding to the target application, and the duration d1 from the start of requesting memory allocation to the process of allocation to memory; The data structure of buffer2 can be shown in Figure 2-3b. The second timestamp t2 when the CPU starts scheduling is recorded in buffer2, the process identifier pid corresponding to the target application and the duration d2 of CPU scheduling; the data structure of buffer3 can be shown in Figure 2 As shown in -3c, buffer3 records the third timestamp t3 at which I/O starts, the process identifier pid corresponding to the target application, and the I/O duration d3.

As an example, assuming that the first system resource is a CPU resource, as shown in Figure 2-3b, the usage records of the first system resource in the first resource linked list buffer2 are arranged in chronological order from top to bottom, assuming that the first resource linked list A total of q usage records can be stored in buffer2, the table entry data1 stores the earliest usage record among the usage records of the first system resource, and the table entry dataq stores the latest usage record among the usage records of the first system resource. Assuming that a total of 3 usage records can be stored in the first resource linked list buffer2, and the timestamps of the 3 usage records are 9:00, 9:05 and 9:10 respectively, the table entry data1 stores the usage records corresponding to 9:00. Item dataq stores usage records corresponding to 9:10.

Optionally, in the first buffer for storing the first system resource, the method for deleting the earliest usage record of the first system resource may include:

It is judged whether all the entries in the first resource linked list are occupied, and when all the entries in the first resource linked list are occupied, the first entry of the first resource linked list is deleted.

For example, as shown in Figure 2-3b, when all q entries in the first resource linked list buffer2 are occupied, deleting the first entry in the first resource linked list is also deleting entry data1, then the original entry data2 becomes the new entry data1, and the original entry dataq becomes the entry dataq-1.

It should be noted that, since only the usage records of the system resources corresponding to the target application are stored in the buffer, the buffer can store the usage records of the system resources corresponding to the target application in the past few seconds, which is convenient for later extraction of the system resources corresponding to the target application. System resource usage records.

Step 2023: Store the latest usage record of the first system resource in the first buffer.

Optionally, the method for storing the latest usage record of the first system resource in the first buffer may include:

An entry is added at the end of the first resource linked list, and the latest usage record of the first system resource is recorded in the added entry.

For example, as shown in FIG. 2-3b, an entry dataq is added after the entry dataq-1 of the first resource linked list buffer2, and the latest usage record of the first system resource is recorded in the entry dataq.

Step 203: Detect whether the display screen of the terminal is stuck.

Optionally, the number of frames of image frames to be drawn by the terminal corresponding to one screen sliding operation on the display interface of the terminal can be preset in the terminal. Assuming that a screen sliding operation is performed on the display interface of the terminal, the terminal needs to draw the frame number. If there are 30 image frames, it can be detected whether the number of user's sliding operations on the display interface within the preset time and the number of image frames drawn by the terminal satisfy the formula: the number of image frames = the number of sliding operations × 30, when When the formula is not satisfied, it is determined that the display screen of the terminal freezes.

Step 204 , when the display screen freezes, lock the n registers to stop updating the system resource usage records in the n registers.

It should be noted that when the display screen freezes, locking the n buffers can prevent the system resource usage records in the n buffers from continuing to be updated, resulting in deletion of the system resource usage records when the display screen freezes.

Step 205: Extract the usage records of m types of system resources.

Optionally, the usage records of m types of system resources corresponding to the target application may be extracted from the locked n buffers.

Step 206: Unlock the n buffers, so that the system resource usage records in the n buffers continue to be updated.

It should be noted that, after extracting the usage records of m types of system resources, the n buffers are unlocked, so that the system resource usage records in the n buffers can be updated.

Step 207: Determine the cause of the freezing of the display screen according to the usage records of the m types of system resources.

Optionally, the usage record may include the usage time period of the system resource. In practical applications, as shown in Figures 2-3a to 2-3c, the usage record may include the start timestamp and the usage duration, according to the start timestamp and the usage duration. Use Duration to get the usage time period of system resources.

Optionally, according to the m types of system resource usage records, the method for determining the cause of the screen freeze, as shown in Figure 2-4, may include:

Step 2071: Acquire the freeze information, where the freeze information includes the freeze time period during which the display screen freezes.

It should be noted that, in the process of detecting whether the display screen of the terminal is stuck, when it is determined that the display screen of the terminal is stuck, the stuck information can be obtained.

Optionally, when the display screen of the terminal is stuck, that is, when there is a "drop frame" in the image frame drawn by the terminal, the time period during which the frame is dropped can be obtained, that is, the freeze time when the display screen freezes. part.

Step 2072: Determine at least one target usage record from the m types of system resource usage records, where the usage time period of the target usage record and the stuck time period overlap.

As an example, assume that the freezing time period is 10 seconds to 11 seconds, and the freezing duration is 1 second. Taking CPU resources as an example, since the duration of a CPU scheduling is generally within 10 milliseconds, the freezing time period In the buffer2, target usage records of multiple time periods can be recorded.

Step 2073: Detect whether there is an abnormal usage record in at least one target usage record.

By way of example, the freeze duration is 1 second as an example, and the threshold is 0.25 seconds, which is a quarter of the freeze duration. When the target usage record is the memory resource usage record, check whether the total duration of the target application from the start of requesting memory allocation to the process of allocating to memory within 1 second exceeds 0.25 seconds. When total1 exceeds 0.25 seconds, determine whether the memory resource There is an abnormal usage record in the usage record; when the target usage record is the usage record of CPU resources, check whether the sum total2 of the duration of CPU scheduling within 1 second is less than 0.75 seconds, and when total2 is less than 0.75 seconds, determine the CPU resource There is an abnormal usage record in the usage record; when the target usage record is the usage record of I/O bandwidth resources, whether the total duration of I/O in 1 second total3 exceeds 0.25 seconds, when total3 exceeds 0.25 seconds, determine the I/O O The usage record of bandwidth resources has abnormal usage records. Or, when total1, total2 and total3 do not satisfy the above conditions, it is determined that the system resource corresponding to the smallest value among (0.25-total1), (total2-0.75) and (0.25-total3) is abnormal.

Step 2074 , when there is an abnormal usage record in at least one target usage record, determine that the cause of the freezing of the display screen is that the system resource corresponding to the abnormal usage record is abnormal.

Optionally, when there is an abnormal usage record in the memory resource usage record, it is determined that the memory resource is abnormal; when there is an abnormal usage record in the CPU resource usage record, it is determined that the CPU resource is abnormal; when the I/O bandwidth resource usage record is abnormal When using the record, it is determined that there is an abnormality in the I/O bandwidth resource.

In practical applications, after determining the cause of the freeze on the display screen, the freeze processing module can perform related processing according to the cause of the freeze. For example, if the cause of the freeze is abnormal CPU resources, the freeze processing module can display the screen on the terminal. Prompt the user to close applications that consume CPU resources in the background.

It should be noted that, the sequence of steps of the method for determining the cause of the jam provided by the embodiment of the present disclosure can be appropriately adjusted, and the steps can also be increased or decreased according to the situation. For example, the positions of step 202 and step 203 can be exchanged.
