The memory allocation method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
In the memory allocation method provided in the embodiment of the present application, an execution main body of the memory allocation method may be an electronic device or a functional module or a functional entity capable of implementing the memory allocation method in the electronic device, the electronic device mentioned in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the memory allocation method provided in the embodiment of the present application is described below with the electronic device as the execution main body.
As shown in fig. 1, an embodiment of the present application provides a memory allocation method, which may include steps 101 to 102:
Specifically, as shown in fig. 2, the electronic device may obtain a memory allocation request of the application, and then the electronic device may first respond to the memory allocation request through a first allocation manner, where 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, when the remaining continuous memory of the system sufficiently satisfies the memory allocation request, the electronic device may directly allocate the remaining continuous memory to the application program through the fast memory allocation path; when the remaining continuous memory of the system is not enough to satisfy the memory allocation request, the electronic device may allocate memory through a slow memory allocation path, that is, trigger memory recycling and memory organizing operations of the system, organize the received fragmented memory blocks into continuous memory, and then allocate the organized continuous memory to the application program.
Optionally, the memory requirement of the memory allocation request may be a non-fragmented continuous memory requirement, for example, at least an order3 memory, that is, a continuous memory greater than or equal to 32K.
With continued reference to fig. 2, if the continuous memory satisfying the memory allocation request cannot be allocated through both the fast memory allocation path and the slow memory allocation path, that is, the normalized continuous memory is still insufficient to satisfy the memory requirement of the memory allocation request, the electronic device may allocate the memory in the reserved memory pool to the application program.
In the embodiment of the present application, under the condition that the continuous memory meeting the memory allocation request is not allocated in the first allocation manner, the memory in the reserved memory pool may be allocated to meet the memory allocation request, that is, the memory in the reserved memory pool may be used, so that the problem that the foreground application process is finished running due to the fact that the memory cannot be applied is solved, thereby reducing the occurrence of the application flash back situation, and further improving the stability of the system under the critical pressure.
Optionally, in order to meet the operation requirement of the application program in the electronic device, the memory size of the reserved memory pool may be determined in the following two ways:
in the method 1, when a system of an electronic device is in a starting state, the electronic device may obtain a first configuration file of a reserved memory pool; determining an initial memory of the reserved memory pool by reading the first configuration file; and then, initializing the reserved memory pool based on the initial memory, wherein the first configuration file is a configuration file issued by the server to the electronic equipment. That is to say, the server may 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 may take effect.
Based on the scheme, the initial memory of the reserved memory pool can be determined according to the first configuration file, so that a background developer can flexibly control the size of the initial memory of the reserved memory pool through the server, and the reserved memory pool can meet memory requirements of different scenes.
In the mode 2, since the application programs installed in the electronic devices of each user are different and the application scenarios are also different, the memory size of the reserved memory pool in different electronic devices can be dynamically adjusted in order to meet the personalized memory requirements of the users. Specifically, under the condition that a system of the electronic device is in an operating state, after the electronic device applies for the memory to the reserved memory pool according to the memory requirement of the memory allocation request, under the condition that the reserved memory pool does not meet the memory requirement, the electronic device may adjust the initial memory corresponding to the first configuration file to obtain a second configuration file; then, updating the first configuration file into a second configuration file; and the initial memory corresponding to the second configuration file is less than or equal to a fourth threshold, and the fourth threshold has an association relation with the system physical memory. That is, the size of the fourth threshold may be determined according to the system physical memory, where the larger the system physical memory is, the larger the fourth threshold is, the smaller the system physical memory is, and the smaller the fourth threshold is.
It should be noted that the second configuration file may be valid after the electronic device is restarted.
Optionally, under the condition that 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 a second configuration file.
Illustratively, 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 firstly, then the configuration file in the electronic device is read, at this time, the configuration file is the first configuration file issued by the server, so that the current initial memory of the reserved memory pool is determined to be 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 requirement, the electronic device can generate a second configuration file in a self-adaptive manner, and the second configuration file is used for indicating that the initial memory of the reserved memory pool is 2X. Then, the electronic device may update the configuration file to a second configuration file, and then when the electronic device is started for the second time, the second configuration file may be directly read, so as to determine that the current initial memory of the reserved memory pool is 2X.
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 needs to be smaller than a fourth threshold, where the fourth threshold is positively correlated with the system physical memory. For example, take the minimum memory unit of the electronic device as 4G, the fourth threshold value
Wherein, memotal is the physical memory of the electronic device, the unit is G, and the fourth threshold value poollimitIs M, the calculation result can be rounded down.
Based on the above scheme, under the condition that the remaining memory in the reserved memory pool does not meet the memory requirement, the electronic device may obtain the second configuration file according to the initial memory corresponding to the first configuration file, and therefore, the initial memory in the reserved memory pool may be flexibly adjusted according to the use scene requirement of the user, so that not only memory waste may be avoided, but also the optimization effect of memory management may be improved.
Optionally, the allocating, by the electronic device, the memory in the reserved memory pool to meet the memory allocation request may specifically include: the electronic equipment applies for the memory from the reserved memory pool according to the memory requirement of the memory allocation request; under the condition that the remaining memory in the reserved memory 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 may successfully allocate the memory through the reserved memory pool.
Based on the above scheme, the electronic device can allocate the memory in the reserved memory pool to satisfy the memory allocation request under the condition that the remaining memory in the reserved memory pool can satisfy the memory requirement, so that the memory pressure of the system can be relieved through the memory in the reserved memory pool, and the occurrence of the application flash back condition is reduced.
Optionally, after allocating the memory in the reserved memory pool to satisfy the memory allocation request, the electronic device may further monitor a memory consumption speed of the reserved memory pool; under the condition that the memory consumption speed is greater than a first threshold value, determining a target application process, and finishing running the target application process, wherein the target application process is an application process with user perception smaller than a second threshold value, and the user perception is the probability of being perceived by a user after the application process is finished running; and finally, performing regularization treatment on the memory released by the target application process after the operation is finished to obtain a continuous memory.
When the memory consumption speed of the reserved memory pool is greater than the first threshold, the memory consumption speed of the reserved memory pool is high, if the remaining memory of the reserved memory pool is increasingly tense, new memory cannot be released, and the remaining memory is insufficient to meet the next memory requirement, the OOM mechanism still may be triggered.
Optionally, the user perception of the application process may be determined according to at least one of: whether it is running in the background, the time it is running from the foreground, the frequency and time the user uses the application process, etc.
Based on the scheme, when the memory consumption speed 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 the continuous memory is obtained through the regularization processing.
Alternatively, the electronic device may determine the memory consumption rate of the reserved memory pool according to the average time interval of the plurality of memory allocation requests. For example, the electronic device may obtain the total time consumption of 10 memory allocation requests, then calculate an average time interval of the 10 memory allocation requests, and finally compare the obtained average time interval with a first threshold, so as to grasp the memory consumption speed of the reserved memory pool, thereby reducing the monitoring pressure of the electronic device.
Optionally, before ending running the target application process, the electronic device may determine a fragmentation degree of a system memory; and if the fragmentation degree is larger than a third threshold value, ending the running of the target application process.
Specifically, the electronic device may monitor the memory consumption speed of the reserved memory pool, report an exception to the upper layer lmkd thread when the memory consumption speed is greater than a first threshold, calculate the memory state of the current system after the lmkd thread receives the exception report sent by the bottom layer, determine, through the process scheduling mechanism, a target application process whose user perception is less than a second threshold if the fragmentation degree is greater than a third threshold, and after the target application process is finished running, send a process killing success signal to the kcompact thread in the kernel, so as to trigger the kcompact thread to perform a process on the memory released by the target application process that is finished running.
Based on the scheme, the judgment of the fragmentation degree of the memory can be carried out before the target application process is finished, so that the success rate of the subsequent memory arrangement processing can be improved.
In the memory allocation method provided by the embodiment of the present application, the execution main body may be a memory allocation device. In the embodiment of the present application, a memory allocation device executing a memory allocation method is taken as an example to describe the memory allocation device provided in the embodiment of the present application.

Optionally, with continued reference to fig. 4, the apparatus 400 may further include a processing module 403. The processing module 403 may be configured to determine a target application process and end running the target application process when the memory consumption speed is greater than a first threshold, where the target application process is an application process with a user perception smaller than a second threshold, and the user perception is a probability of being perceived by a user after the application process is ended running; and regulating the memory released by the target application process after the operation is finished to obtain a continuous memory.
