[0033] Figure 1A flow chart of a memory allocation method provided in an embodiment of the present disclosure is provided. The embodiment of the present disclosure is applicable to the situation of memory allocation in a client. The method can be executed by a memory allocation device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal such as a mobile phone, a smart watch, a tablet computer, and a personal digital assistant.

[0034] like Figure 1 As shown, the method includes:

[0035] Step 101: When the application is running, a first preset number of initial memory pools is created by starting a memory allocator of the local memory, wherein the first preset number is determined at compile time.

[0036] The embodiments of the present disclosure do not limit the type of operating system in the electronic device, for example, it may be an Android operating system. For ease of description, the following description will take the Android operating system as an example.

[0037] For Android applications, in addition to the Java memory management in the Android virtual machine, there is also Native memory in the non-Java runtime environment that needs to be managed. For example, when the player plays videos (video playback function), the camera shoots and edits (video shooting and editing function), and images need to be rendered (image rendering function), these functional modules usually do not apply directly from Java memory when applying for memory, but apply for Native memory. The memory allocator commonly used by Native memory is Jemalloc. Jemalloc is a high-performance, multi-threaded and scalable memory allocator that is suitable for various platforms and application scenarios. It has the advantages of reducing memory fragmentation, improving CPU cache utilization and taking advantage of multi-core processors. For Jemalloc, each thread has a local cache (thread cache) to cache allocated and released memory blocks, reducing lock contention between caches and different threads. Jemalloc provides multiple memory pools (Arena, also known as memory management unit, used to manage a set of continuous memory areas) to meet the memory management needs in multi-threaded scenarios. By using multiple memory pools, threads can be distributed among different memory pools, thereby reducing competition for memory access. For memory allocation within the memory pool, local locks are used to protect concurrent access and avoid data contention.

[0038] Exemplarily, the default number of memory pools is determined at compile time and is recorded as the first preset number, which can be understood as the maximum number of default memory pools. For mobile terminals, the first preset number is usually 1 to 2. After the application process is started, the first preset number is read, and during the initialization process after the memory allocator is started, the first preset number of memory pools is created, which is recorded as the initial memory pool.

[0039] Taking the memory allocator Jemalloc as an example, after Jemalloc is enabled, in the initialization process, Arena is created by calling the internal method arena_new, that is, the initial memory pool is created.

[0040] Step 102: Send a first dynamic parameter value by calling a preset parameter sending function to create a second preset number of newly added memory pools, wherein the first dynamic parameter value is used to indicate a newly created memory pool.

[0041] For existing mobile terminals, 1 to 2 memory pools are usually set by default, the concurrency of local memory allocation is not high, and the memory allocation efficiency is not ideal. In the disclosed embodiment, the number of memory pools can be increased when the application is running to reduce multi-thread lock competition, increase memory application concurrency, improve memory allocation efficiency, and reduce the average CPU usage. A method for creating a new memory pool can be to create it by calling a preset parameter sending function to send a first dynamic parameter value. This creation method is not limited by the first preset number that is hard-coded during compilation.

[0042] Exemplarily, taking the memory allocator as Jemalloc as an example, the preset parameter delivery function may be the mallctl function, and the first dynamic parameter value may be arenas.extend or arenas.create. Before executing this step, the process may further include: determining the system version of the current operating system, and determining the first dynamic parameter value as arenas.extend or arenas.create according to the system version.

[0043] Taking arenas.extend as an example, after arenas.extend is issued, the creation of Arena will be triggered through the following path: anrea_extend_ctl->ctl_grow->anrea_init->arena_init_locked->anrea_new, that is, the creation of a new memory pool is realized.

[0044] It should be noted that the creation of the second preset number of newly added memory pools may be centralized or dynamically created in batches, that is, the newly added memory pools are created when they are needed, without any specific limitation.

[0045] Step 103: Allocate memory for threads based on the initial memory pool and the newly added memory pool.

[0046] Exemplarily, when a memory allocation request of a thread is received, a suitable memory pool may be selected from a first preset number of initial memory pools and a second preset number of newly added memory pools to allocate memory to the thread, and the specific selection method is not limited.

[0047] The memory allocation method provided by the embodiment of the present disclosure creates a first preset number of initial memory pools by starting the memory allocator of the local memory when the application is running, wherein the first preset number is determined at compile time, and creates a second preset number of newly added memory pools by calling the preset parameter sending function to send the first dynamic parameter value, wherein the first dynamic parameter value is used to indicate the newly created memory pool, and performs thread memory allocation based on the initial memory pool and the newly added memory pool. By adopting the above technical solution, on the basis of creating a certain number of initial memory pools determined at compile time when the application is running, more memory pools are created by sending dynamic parameters, so that more memory pools can participate in the memory allocation of threads, which can improve the concurrency of local memory allocation, improve memory allocation efficiency, improve application performance, and thus improve user experience.

[0048] Figure 2 This is a flow chart of another memory allocation method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized based on each optional solution in the above embodiment. Specifically, the method includes the following steps:

[0049] Step 201: When the application is running, a first preset number of initial memory pools are created by starting a memory allocator of the local memory.

[0050] Step 202: Send the first dynamic parameter value by calling the preset parameter sending function to create a second preset number of newly added memory pools.

[0051] Step 203: configure a first memory pool identifier for the first newly added memory pool, and establish a corresponding relationship between the first memory pool identifier and a preset dynamic library.

[0052] Exemplarily, in order to facilitate the use of appropriate memory pools for different threads for memory allocation in the later stage, when creating a new memory pool, an identifier for identifying the identity of the new memory pool is configured for the memory pool, which is recorded as a memory pool identifier, for example, a memory pool id. The first new memory pool may be one or more new memory pools in the second preset number of new memory pools created. The memory pool identifier of the first new memory pool is recorded as the first memory pool identifier.

[0053] Exemplarily, the preset dynamic library may include the dynamic library corresponding to the functional module that needs to apply for local memory, such as the dynamic library corresponding to the video playback module, the dynamic library corresponding to the camera module, etc., and may also include the dynamic library corresponding to the virtual machine, etc., which can be set according to actual needs. The specific number of preset dynamic libraries is not limited. When there are multiple preset dynamic libraries, a corresponding first newly added memory pool can be configured for each preset dynamic library, and the second preset number can be set according to the number of preset dynamic libraries. For example, the second preset number is greater than or equal to the number of preset dynamic libraries. The correspondence between the first memory pool identifier and the preset dynamic library can be a one-to-one relationship or a one-to-many relationship. Among them, the corresponding relationship can specifically be a correspondence between the name of the preset dynamic library and the first memory pool identifier.

[0054] Step 204: In response to the target thread created by the preset dynamic library being started, a binding relationship between the target thread and a first memory pool identifier corresponding to the preset dynamic library is established.

[0055] Exemplarily, the preset dynamic library can create one or more threads, recorded as target threads. After detecting that the target thread is started, the corresponding newly added memory pool is bound to the target thread, that is, a binding relationship is established between the target thread and the first memory pool identifier corresponding to the preset dynamic library to which the target thread belongs.

[0056] For example, there is a corresponding relationship between the preset dynamic library A and the first memory pool identifier a. When the preset dynamic library A creates the target thread 1, after the target thread 1 is started, a binding relationship between the target thread 1 and the first memory pool identifier a is established. Subsequently, if the preset dynamic library A creates the target thread 2, after the target thread 2 is started, a binding relationship between the target thread 2 and the first memory pool identifier a is established.

[0057] Optionally, this step may specifically include: detecting that the target thread created by the preset dynamic library calls a thread naming function, issuing a second dynamic parameter value by calling the preset parameter issuing function, and establishing a binding relationship between the target thread and the first memory pool identifier corresponding to the preset dynamic library, wherein the second dynamic parameter value includes a parameter value for indicating the binding thread and the memory pool, and the first memory pool identifier corresponding to the preset dynamic library. In this way, the start of the target thread can be accurately detected without relying on the source code environment, that is, without knowing the source code of the system library, and the establishment of the binding relationship can be completed within the target thread.

[0058] Exemplarily, a hook function may be used to detect the call of a thread naming function, such as pthread_setname_np. The parameter value for indicating the binding of a thread and a memory pool may be thread.arena. The mallctl function sends thread.arena and the memory pool ID to be bound, thereby implementing the binding of the current target thread and the memory pool ID.

[0059] Step 205: Allocate memory for the thread based on the initial memory pool and the newly added memory pool.

[0060] This step may include: in response to a memory allocation request of the target thread, allocating memory for the target thread based on a first newly added memory pool to which a first memory pool identifier having a binding relationship with the target thread belongs.

[0061] Exemplarily, for a target thread that has established a binding relationship, when the target thread needs to apply for memory, the memory allocation request of the target thread can be responded to, the first newly added memory pool to which the current target thread is bound can be determined, and memory allocation can be performed based on the first newly added memory pool bound to the target thread. As in the above example, when target thread 1 or target thread 2 applies for memory, memory allocation for target thread 1 or target thread 2 can be performed based on the first newly added memory pool to which the first memory pool identifier a belongs. It can be seen that threads created by the same preset dynamic library will be bound to the same newly added memory pool, that is, threads created by the same preset dynamic library apply for memory from the same newly added memory pool.

[0062] Optionally, this step may further include: in response to a memory allocation request of the first thread, when it is determined that the first thread is not bound to any of the newly added memory pools, allocating memory for the first thread based on the initial memory pool. Thus, it can be ensured that the memory allocation request of the unbound thread can be responded to in a timely and accurate manner based on the initial memory pool, so that the memory requested by each thread is more reasonably distributed in each memory pool.

[0063] The memory allocation method provided by the embodiment of the present disclosure configures a memory pool identifier for the newly added memory pool after creating a new memory pool, and establishes a corresponding relationship between a preset dynamic library and the memory pool identifier; after the thread created by the preset dynamic library is started, a binding relationship between the thread and the newly added memory pool is established, thereby using the preset dynamic library as a division dimension, concentrating the memory allocation needs of threads created by the same preset dynamic library into the same newly added memory pool, and making the distribution of memory applied for by each thread in each memory pool more reasonable.

[0064] Figure 3 This is a flow chart of another memory allocation method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized based on each optional solution in the above embodiment. Specifically, the method includes the following steps:

[0065] Step 301: When the application is running, a first preset number of initial memory pools are created by starting a memory allocator of the local memory.

[0066] Step 302: Send the first dynamic parameter value by calling the preset parameter sending function to create a second preset number of newly added memory pools.

[0067] Step 303: configure a second memory pool identifier for the second newly added memory pool, and establish a corresponding relationship between the second memory pool identifier and a preset thread.

[0068] The second newly added memory pool may be one or more newly added memory pools in the created second preset number of newly added memory pools. The memory pool identifier of the second newly added memory pool is recorded as the second memory pool identifier.

[0069] Exemplarily, the preset threads may include threads with longer running time, that is, threads with running time greater than a preset time threshold during the running of the application, such as rendering threads. During the running of the application, the rendering thread needs to render data to realize page display, so an independent new memory pool can be set for the rendering thread. The corresponding relationship between the second memory pool identifier and the preset thread can be a one-to-one relationship or a one-to-many relationship.

[0070] Step 304: In response to the preset thread being started, a binding relationship between the preset thread and a second memory pool identifier corresponding to the preset thread is established.

[0071] Optionally, this step may specifically include: in response to the preset thread calling the data rendering function, issuing a third dynamic parameter value by calling the preset parameter issuing function, establishing a binding relationship between the preset thread and the second memory pool identifier corresponding to the preset thread, wherein the third dynamic parameter value includes a parameter value for indicating the binding thread and the memory pool, and the second memory pool identifier corresponding to the preset thread. In this way, the startup of the preset thread can be accurately detected without relying on the source code environment, that is, without knowing the source code of the system library, and the establishment of the binding relationship can be completed within the preset thread.

[0072] Exemplarily, a hook function may be used to detect the call of a data rendering function, such as eglSwapBuffersWithDamageKHR. The parameter value for indicating the binding of a thread and a memory pool may be thread.arena. The mallctl function sends thread.arena and the memory pool id to be bound, thereby implementing the binding of a preset thread and a memory pool id.

[0073] Step 305: Allocate memory for the thread based on the initial memory pool and the newly added memory pool.

[0074] This step may include: in response to a memory allocation request of the preset thread, allocating memory to the preset thread based on a second newly added memory pool to which a second memory pool identifier having a binding relationship with the preset thread belongs.

[0075] Exemplarily, for a preset thread that has established a binding relationship, when the preset thread needs to apply for memory, the memory allocation request of the preset thread can be responded to, the second newly added memory pool to which the current preset thread is bound can be determined, and memory allocation can be performed based on the bound second newly added memory pool. As in the above example, when the rendering thread applies for memory, the memory allocation of the rendering thread can be performed based on the second newly added memory pool to which the rendering thread belongs. It can be seen that the memory application of the same preset thread with a longer running time can be handled by the bound newly added memory pool.

[0076] Optionally, this step may further include: in response to a memory allocation request of the first thread, when it is determined that the first thread is not bound to any of the newly added memory pools, allocating memory for the first thread based on the initial memory pool. Thus, it can be ensured that the memory allocation request of the unbound thread can be responded to in a timely and accurate manner based on the initial memory pool, so that the memory requested by each thread is more reasonably distributed in each memory pool.

[0077] The memory allocation method provided by the embodiment of the present disclosure configures a memory pool identifier for the newly added memory pool after creating a new memory pool, and establishes a corresponding relationship between a preset thread and the memory pool identifier. After the preset thread is started, a binding relationship between the preset thread and the newly added memory pool is established, so that the memory application of the same preset thread with a longer running time is processed by the bound newly added memory pool, so that the distribution of the memory applied by each thread in each memory pool is more reasonable.

[0078] Optionally, in the case where the preset thread is a rendering thread, since the rendering thread is created earlier after the application is started, the establishment of the newly added memory pool corresponding to the rendering thread and the binding with the memory pool identifier can be completed after the preset thread is started. For example, in response to the preset thread calling the data rendering function, the first dynamic parameter value is sent by calling the preset parameter sending function, the newly added memory pool corresponding to the preset thread is created, and the second memory pool identifier is configured for the newly added memory pool corresponding to the preset thread, and the third dynamic parameter value is sent by calling the preset parameter sending function to establish a binding relationship between the preset thread and the second memory pool identifier corresponding to the preset thread.

[0079] Figure 4This is a flow chart of another memory allocation method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized based on each optional solution in the above embodiment. Specifically, the method includes the following steps:

[0080] Step 401: When the application is running, a first preset number of initial memory pools are created by starting a memory allocator of the local memory.

[0081] Step 402: Send the first dynamic parameter value by calling the preset parameter sending function to create a second preset number of newly added memory pools.

[0082] Optionally, the second preset number may be determined according to the sum of the number of preset dynamic libraries and the number of preset threads.

[0083] Step 403: configure a first memory pool identifier for the first newly added memory pool, and establish a corresponding relationship between the first memory pool identifier and a preset dynamic library; configure a second memory pool identifier for the second newly added memory pool, and establish a corresponding relationship between the second memory pool identifier and a preset thread.

[0084] Step 404: In response to the preset thread calling the data rendering function, a third dynamic parameter value is issued by calling the preset parameter issuing function, and a binding relationship between the preset thread and the second memory pool identifier corresponding to the preset thread is established.

[0085] Step 405: In response to the memory allocation request of the preset thread, memory allocation for the preset thread is performed based on the second newly added memory pool to which the second memory pool identifier having a binding relationship with the preset thread belongs.

[0086] Step 406: Detect that the target thread created by the preset dynamic library calls the thread naming function, issue the second dynamic parameter value by calling the preset parameter issuing function, and establish a binding relationship between the target thread and the first memory pool identifier corresponding to the preset dynamic library.

[0087] Step 407: In response to the memory allocation request of the target thread, memory allocation is performed for the target thread based on the first newly added memory pool to which the first memory pool identifier having a binding relationship with the target thread belongs.

[0088] Step 408: In response to the memory allocation request of the first thread, if it is determined that the first thread is not bound to any of the newly added memory pools, memory allocation for the first thread is performed based on the initial memory pool.

[0089] In the disclosed embodiment, a correspondence between a preset dynamic library and a memory pool identifier is established, and a correspondence between a preset thread and a memory pool identifier is also established, thereby achieving two different modes of binding threads and memory pools to coexist, making the distribution of memory requested by each thread in each memory pool more reasonable.

[0090] Figure 5 This is a flow chart of another memory allocation method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized based on each optional solution in the above embodiment. Specifically, the method includes the following steps:

[0091] Step 501: When the application is running, a first preset number of initial memory pools are created by starting a memory allocator of the local memory.

[0092] Step 502: Send the first dynamic parameter value by calling the preset parameter sending function to create a second preset number of newly added memory pools.

[0093] Step 503: Use the dynamic loading function to obtain the address of the memory pool quantity variable, and modify the original variable value in the address to the target variable value, wherein the original variable value is determined according to the first preset quantity, and the target variable value is determined according to the sum of the first preset quantity and the second preset quantity.

[0094] Exemplarily, the dynamic loading function may be a dlsym function, the variable for the number of memory pools may be narenas_auto, and the corresponding variable value may be je_narenas_auto. The dynamic loading function may be used to accurately obtain the address of the variable for the number of memory pools, and to safely modify the original variable value to the target variable value. The original variable value is a read-only value after the memory allocator is initialized. By modifying it in the above manner, the number of memory pools after the newly added memory pool is created may be safely modified, so that the subsequent memory request of the thread may be allocated to the newly added memory pool instead of just to the initialized memory pool.

[0095] Step 504: In response to the memory allocation request of the second thread, based on the variable value of the current memory pool quantity variable, poll the initial memory pool and the newly added memory pool to find the target memory pool with the least number of currently mounted threads from the initial memory pool and the newly added memory pool, and perform memory allocation for the second thread based on the target memory pool.

[0096] Exemplarily, when the second thread applies for memory, it can poll the currently created initial memory pool and the newly added memory pool based on the variable value of the current memory pool quantity variable, that is, the modified target variable value, and find the target memory pool with the least number of currently mounted threads, and allocate memory for the second thread based on the target memory pool. At different times, the target memory pool may be the initial memory pool or the newly added memory pool. Through the above dynamic allocation method, the balance of memory allocation in each memory pool can be guaranteed.

[0097] The memory allocation method provided by the embodiment of the present disclosure creates more memory pools by dynamically issuing parameters on the basis of a certain number of initial memory pools determined at compile time when the application is running, so that more memory pools can participate in the memory allocation of threads, which can improve the concurrency of local memory allocation and the memory allocation efficiency. The variable value of the memory pool quantity variable can be safely modified by using a dynamic loading function. By dynamically allocating memory pools for the memory application of threads, the association between memory pools and threads can be automatically completed, thereby further improving the memory allocation efficiency.

[0098] Figure 6 A schematic diagram of the structure of a memory allocation device provided by an embodiment of the present disclosure is shown in FIG. Figure 6 As shown, the device comprises:

[0099] An initial memory pool creation module 601 is used to create a first preset number of initial memory pools by starting a memory allocator of a local memory when the application is running, wherein the first preset number is determined at compile time;

[0100] A new memory pool creation module 602 is used to create a second preset number of new memory pools by issuing a first dynamic parameter value by calling a preset parameter issuing function, wherein the first dynamic parameter value is used to indicate a new memory pool;

[0101] The memory allocation module 603 is used to allocate memory for threads based on the initial memory pool and the newly added memory pool.

[0102] The memory allocation device provided by the embodiment of the present disclosure creates a first preset number of initial memory pools by starting the memory allocator of the local memory when the application is running, wherein the first preset number is determined at compile time, and creates a second preset number of newly added memory pools by calling the preset parameter sending function to send the first dynamic parameter value, wherein the first dynamic parameter value is used to indicate the newly created memory pool, and performs thread memory allocation based on the initial memory pool and the newly added memory pool. By adopting the above technical solution, on the basis of creating a certain number of initial memory pools determined at compile time when the application is running, more memory pools are created by sending dynamic parameters, so that more memory pools can participate in the memory allocation of threads, which can improve the concurrency of local memory allocation and improve memory allocation efficiency.

[0103] Optionally, the device further comprises:

[0105] A first binding relationship establishing module is used for establishing a binding relationship between the target thread and a first memory pool identifier corresponding to the preset dynamic library in response to the start of a target thread created by the preset dynamic library before memory allocation of the thread is performed based on the initial memory pool and the newly added memory pool;

[0106] Wherein, the memory allocation module includes:

[0107] The first allocation unit is configured to respond to a memory allocation request of the target thread and allocate memory to the target thread based on a first newly added memory pool to which a first memory pool identifier having a binding relationship with the target thread belongs.

[0108] Optionally, the first binding relationship establishing module is specifically used to: detect that the target thread created by the preset dynamic library calls a thread naming function, and issue a second dynamic parameter value by calling the preset parameter issuing function to establish a binding relationship between the target thread and the first memory pool identifier corresponding to the preset dynamic library, wherein the second dynamic parameter value includes a parameter value for indicating the binding thread and the memory pool, and the first memory pool identifier corresponding to the preset dynamic library.
