Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The memory allocation method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

In the memory allocation method provided by the embodiment of the present application, the execution body of the memory allocation method may be an electronic device or a functional module or functional entity in the electronic device that can implement the memory allocation method. The electronic device mentioned in the embodiment of the present application includes but does not Limited to a mobile phone, a tablet computer, a computer, a camera, a wearable device, etc., the following describes the memory allocation method provided by the embodiment of the present application by taking an electronic device as an execution subject as an example.

As shown in FIG. 1 , an embodiment of the present application provides a memory allocation method, and the method may include steps 101 to 102:

Step 101, the electronic device obtains a memory allocation request.

When an electronic device wants to run an application program normally, it must successfully apply for the memory that can maintain the running of the application program. Specifically, as shown in Figure 2, the electronic device can obtain the memory allocation request of the application program. After that, the electronic device The memory allocation request may be responded to first through a first allocation manner, and the first allocation manner may include at least one of the following: a fast memory allocation path and a slow memory allocation path. That is to say, when the remaining contiguous memory of the system is sufficient to satisfy the memory allocation request, the electronic device can directly allocate the remaining contiguous memory to the application through the fast memory allocation path; when the remaining contiguous memory of the system is insufficient to satisfy the memory allocation request , the electronic device can allocate memory through the slow memory allocation path, that is, trigger the system's memory reclamation and memory reorganization operations, reorganize the recovered and fragmented memory blocks into contiguous memory, and then allocate the reorganized contiguous memory to the app.

Optionally, the memory requirement of the above memory allocation request may be a non-fragmented contiguous memory requirement, for example, at least order3 memory, that is, a contiguous memory greater than or equal to 32K.

Step 102: In the case that the contiguous memory that satisfies the memory allocation request is not allocated by the first allocation method, the electronic device allocates the memory in the reserved memory pool to satisfy the memory allocation request.

Continuing to refer to FIG. 2, if both the fast memory allocation path and the slow memory allocation path fail to allocate contiguous memory that satisfies the memory allocation request, that is, the regularized contiguous memory is still insufficient to meet the memory requirement of the memory allocation request, Then the electronic device can allocate the memory in the reserved memory pool to the application.

In the embodiment of the present application, since the first allocation method does not allocate contiguous memory that satisfies the memory allocation request, the memory in the reserved memory pool can be allocated to satisfy the memory allocation request, that is, the reserved memory can be used Therefore, it can alleviate the problem that the foreground application process is terminated due to insufficient memory, thereby reducing the occurrence of application flashback and improving the stability of the system under critical pressure.

Optionally, in order to meet the running requirements of the application in the electronic device, the memory size of the above-mentioned reserved memory pool can be determined in the following two ways:

Mode 1, when the system of the electronic device is in the startup state, the electronic device can obtain the first configuration file of the reserved memory pool; and determine the initial memory of the reserved memory pool by reading the first configuration file; then, based on The initial memory initializes the reserved memory pool, and the first configuration file is a configuration file issued by the server to the electronic device. That is, the server can modify the memory size of the reserved memory pool by issuing the first configuration file, and when the electronic device is restarted, the newly issued first configuration file can take effect.

Based on the above solution, since the initial memory of the reserved memory pool can be determined according to the first configuration file, the background developer can flexibly control the size of the initial memory of the reserved memory pool through the server, so that the reserved memory pool can meet the Memory requirements for different scenarios.

Mode 2, since each user's electronic device has different application programs and different application scenarios, in order to meet the user's personalized memory requirements, the memory size of the reserved memory pools in different electronic devices can be dynamically adjusted. Specifically, when the system of the electronic device is in the running state, after the electronic device applies for memory from the reserved memory pool according to the memory requirement of the memory allocation request, if the reserved memory pool does not meet the memory requirement, the electronic device The initial memory corresponding to the first configuration file can be adjusted to obtain the second configuration file; then, the first configuration file is updated to the second configuration file; wherein, the initial memory corresponding to the second configuration file is less than or equal to the fourth threshold, The fourth threshold is associated with the system physical memory. That is, the size of the fourth threshold can be determined according to the system physical memory, the larger the system physical memory, the larger the fourth threshold, and the smaller the system physical memory, and the smaller the fourth threshold.

It should be noted that the above-mentioned second configuration file may take effect after the electronic device is restarted.

Optionally, when the reserved memory pool does not meet the memory requirement, the electronic device may adjust the initial memory corresponding to the first configuration file according to a preset multiple to obtain the second configuration file.

Exemplarily, as shown in FIG. 3 , the preset multiple is 2 as an example. When the electronic device is started for the first time, the initialization of the system can be completed first, and then the configuration file in the electronic device can be read. At this time, the configuration file is the first configuration file issued by the server, so as to determine the current value of the reserved memory pool. The initial memory is X. After the electronic device runs for a period of time, if the remaining memory in the reserved memory pool cannot meet the current memory requirements, the electronic device can adaptively generate a second configuration file, which is used to indicate the preset memory. The initial memory of the reserved memory pool is 2X. After that, the electronic device can update the configuration file to the second configuration file, and then when the electronic device is started for the second time, it can directly read the second configuration file, thereby determining that the current initial memory of the reserved memory pool is 2X.

其中，memtotal为电子设备的物理内存，单位为G，第四阈值pool_limit的单位为M，计算结果可以向下取整。It should be noted that the electronic device needs to adjust the initial memory of the reserved memory pool according to the system physical memory, and the adjusted initial memory of the reserved memory pool must be less than a fourth threshold, which is positively related to the system physical memory. For example, taking the minimum memory unit of an electronic device as 4G, the fourth threshold

Among them, memtotal is the physical memory of the electronic device, the unit is G, and the unit of the fourth threshold pool _limit is M, and the calculation result can be rounded down.

Based on the above solution, since the remaining memory in the reserved memory pool does not meet the memory requirement, the electronic device can obtain the second configuration file by adjusting the initial memory corresponding to the first configuration file. Therefore, the initial The memory can be flexibly adjusted according to the needs of the user's usage scenarios. In this way, it can not only avoid memory waste, but also improve the optimization effect of memory management.

Optionally, the electronic device allocates memory in the reserved memory pool to meet the memory allocation request, which may specifically include: the electronic device applies for memory from the reserved memory pool according to the memory requirement of the memory allocation request; When the remaining memory in the pool can meet the memory requirement, the electronic device can allocate the memory in the reserved memory pool to meet the memory allocation request. That is, when the remaining memory in the reserved memory pool is greater than or equal to the memory requirement corresponding to the memory allocation request, the electronic device can successfully allocate memory through the reserved memory pool.

Based on the above solution, since the electronic device can allocate the memory in the reserved memory pool to meet the memory allocation request under the condition that the remaining memory in the reserved memory pool can meet the memory requirement, the memory in the reserved memory pool can be allocated by the electronic device. Relieve the memory pressure of the system, thereby reducing the occurrence of application flashbacks.

Optionally, after allocating memory in the reserved memory pool to satisfy the memory allocation request, the electronic device may also monitor the memory consumption speed of the reserved memory pool; and when the memory consumption speed is greater than the first threshold Next, determine a target application process, and end running the target application process, where the target application process is an application process with a user perception degree less than a second threshold, and the user perception degree is the probability of being perceived by the user after finishing running the application process; Finally, regular processing is performed on the memory released by the end of running the target application process to obtain continuous memory.

When the memory consumption rate of the reserved memory pool is greater than the first threshold, it means that the memory consumption rate of the reserved memory pool is relatively fast. If it is not enough to meet the next memory demand, the OOM mechanism may still be triggered. Therefore, in order to avoid this situation, the electronic device can filter out the user perception when monitoring that the memory consumption rate of the reserved memory pool is greater than the first threshold. The target application process whose degree is less than the second threshold is terminated, and the running of the target application process is terminated, thereby releasing the memory occupied by the target application process.

Optionally, the user perception of the application process may be determined according to at least one of the following: whether it is running in the background, the time from running in the foreground, the frequency and time at which the user uses the application process, and the like.

Based on the above solution, when the memory consumption rate of the reserved memory pool is greater than the first threshold, the memory can be released by ending the running of the target application process, and continuous memory can be obtained through regular processing. Since the user perception of the target application process is less than the second threshold , therefore, the continuous memory can be expanded under the premise of taking into account the user experience, thereby improving the memory allocation speed of the next memory application.

Optionally, the electronic device may determine the memory consumption speed of the reserved memory pool according to the average time interval of multiple memory allocation requests. For example, the electronic device can obtain the total time-consuming of 10 memory allocation requests, then calculate the average time interval of the 10 memory allocation requests, and finally, compare the obtained average time interval with the first threshold, so as to grasp the reserved memory pool The speed of memory consumption is reduced, thereby reducing the monitoring pressure of electronic devices.

Optionally, before ending the running of the target application process, the electronic device may first determine the degree of fragmentation of the system memory; if the degree of fragmentation is greater than the third threshold, the electronic device ends the running of the target application process.

Specifically, the electronic device can monitor the memory consumption rate of the reserved memory pool, and report an exception to the upper-layer lmkd thread when the memory consumption rate is greater than the first threshold. When the lmkd thread receives the exception report sent by the lower layer, it can first calculate the current system If the fragmentation degree is greater than the third threshold, the target application process whose user perception is less than the second threshold is determined by the process ranking mechanism. After the target application process ends, the lmkd thread can send a kill to the kcompact thread in the kernel. The process success signal, which triggers the kcompact thread to perform regular processing on the memory released by the end running the target application process.

Based on the above solution, since the degree of memory fragmentation can be judged before ending the running of the target application process, the success rate of subsequent memory regularization processing can be improved.

In the memory allocation method provided by the embodiment of the present application, the execution body may be a memory allocation device.
