[0057] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0065] Figure 6 A block diagram of an electronic device 1900 provided in an embodiment of this disclosure is shown. Detailed Implementation

[0066] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0067] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0068] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0069] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0070] This disclosure provides a resource creation method. In response to a resource creation request, the method determines the amount of video memory requested corresponding to the request. In response to the resource creation request satisfying a preset partitioning condition, the method maps the resource creation request to at least two video memory allocation requests. The preset partitioning condition includes at least: the amount of video memory requested corresponding to the resource creation request is greater than a preset allocation threshold; the amount of video memory requested corresponding to any one of the at least two video memory allocation requests is less than or equal to the preset allocation threshold; video memory allocation is requested based on the at least two video memory allocation requests; at least two video memory allocation results are obtained corresponding to the at least two video memory allocation requests; and a target resource corresponding to the resource creation request is created based on the at least two video memory allocation results. Therefore, by mapping a resource creation request with a large amount of video memory requested to at least two video memory allocation requests with smaller amounts of video memory requested during resource creation, the success rate of video memory allocation and resource creation can be improved. This not only improves the stability of application operation but also increases the number of applications running simultaneously with the same amount of video memory resources.

[0071] The resource creation method provided in the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0072] Figure 1 A flowchart illustrating a resource creation method provided in an embodiment of this disclosure is shown. In one possible implementation, the entity executing the resource creation method may be a resource creation device, such as a terminal device, server, or other electronic device. The terminal device may be a user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, in-vehicle device, or wearable device, etc. In some possible implementations, the resource creation method may be implemented by a processor calling computer-readable instructions stored in memory. Figure 1 As shown, the resource creation method includes steps S11 to S14.

[0073] In step S11, in response to the resource creation request, the amount of video memory requested corresponding to the resource creation request is determined.

[0074] In step S12, in response to the resource creation request satisfying a preset partitioning condition, the resource creation request is mapped to at least two video memory allocation requests; wherein, the preset partitioning condition includes at least: the amount of video memory requests corresponding to the resource creation request is greater than a preset allocation threshold; and the amount of video memory requests corresponding to any one of the at least two video memory allocation requests is less than or equal to the preset allocation threshold.

[0075] In step S13, according to the at least two memory allocation requests, memory allocation is requested, and at least two memory allocation results corresponding to the at least two memory allocation requests are obtained.

[0076] In step S14, based on the at least two memory allocation results, the target resource corresponding to the resource creation request is created.

[0077] In this embodiment of the disclosure, when an application (APP) needs to create a new resource, it can initiate a resource creation request. Hereinafter, the resource requested by the application to be created will be referred to as the target resource.

[0078] In one possible implementation, the application can initiate a resource creation request by calling a graphics API (Application Programming Interface). For example, the graphics API could be Direct3D.

[0079] In one possible implementation, the resource creation request may include type information of the target resource.

[0080] In one possible implementation, the target resource includes at least one type: texture, buffer, or rendering target.

[0081] In this implementation, the resource type can be a texture, a buffer, a render target, etc., and there are no restrictions here.

[0082] In graphics rendering, textures are resources used to store image data that can be mapped onto the surface of a 3D model to provide detail and color information.

[0083] Buffers are data storage resources that can be used to store vertex data, index data, or other types of data that are used by the GPU during rendering. For example, depth buffers can store depth information to help determine which pixels should be rendered in front; constant buffers can store data that does not change frequently, such as transformation matrices and lighting parameters; index buffers can store vertex indices, which are used to determine which vertices make up a polygon; and so on.

[0084] A rendering target is a special buffer used to store the results of rendering operations. For example, a framebuffer is a common rendering target; it stores the final rendered image, which can be displayed on the screen or used for further processing.

[0085] In one possible implementation, the resource creation request may include characteristic information of the target resource, which may include the size of the target resource. For example, an app might need to create a 64MB texture resource to store image data.

[0086] In this embodiment of the disclosure, the amount of video memory requested corresponding to the resource creation request can refer to the amount of video memory that needs to be allocated to satisfy the resource creation request.

[0087] In one possible implementation, the amount of video memory requested corresponding to the resource creation request can be determined based on the size of the target resource.

[0088] As an example of this implementation, the size of the target resource can be determined as the amount of video memory requested by the resource creation request. For example, if the resource creation request requests the creation of a 64MB texture resource, the amount of video memory requested by the resource creation request can be 64MB.

[0089] As another example of this implementation, the amount of video memory requested for a resource creation request can be slightly larger than the size of the target resource.

[0090] In one possible implementation, the User Mode Driver (UMD) can respond to a resource creation request and determine the amount of video memory requested corresponding to that resource creation request.

[0091] In this embodiment of the disclosure, in response to a resource creation request satisfying a preset partitioning condition, the resource creation request can be mapped to at least two memory allocation requests. The preset partitioning condition can refer to a pre-set condition used to determine whether to partition the resource creation request. Partitioning the resource creation request can mean decomposing a resource creation request with a large memory request into two or more memory allocation requests with smaller memory requests.

[0092] The preset partitioning conditions include at least the following: the memory request amount corresponding to the resource creation request is greater than a preset allocation threshold. The preset allocation threshold can represent a pre-defined upper limit for the memory request amount of a memory allocation request. For example, if the memory request amount corresponding to a resource creation request is A, the preset allocation threshold is t, and the resource creation request meets the preset partitioning conditions, then the resource creation request can be mapped to... One video memory allocation request, of which This indicates rounding up to the nearest integer.

[0093] In one possible implementation, the preset partitioning condition further includes at least one of the following: the target resource is a non-shared resource; the target resource is not allowed to be modified by the CPU after its creation.

[0094] As an example of this implementation, the predefined partitioning condition also includes: the target resource is a non-shared resource. A non-shared resource is one that, after creation, is used only by one application or a specific context and is not shared by multiple applications or processes. In this case, the resource's usage scenario is relatively independent, so the resource creation request can be split into multiple small memory allocation requests without worrying about shared access issues between multiple users. For example, a texture resource in a game might only be used by one scene and not shared by other scenes or modules. In this case, the resource creation request can be mapped to multiple memory allocation requests.

[0095] As an example of this implementation, the preset partitioning condition also includes: the target resource cannot be modified by the CPU after creation. This means that the resource is read-only from the CPU's perspective after creation, and its content will not be modified by the CPU during subsequent use. For unmodifiable resources, more flexible memory allocation is possible because there is no need to worry about subsequent modifications affecting the integrity or consistency of the resource. For example, some static texture resources (such as background textures in games) will not be modified by the CPU after loading. In this case, the resource creation request can be split into multiple smaller allocation requests, thereby improving the success rate of memory allocation.

[0096] In this implementation, by restricting the sharing and modifiability of resources when dividing resource creation requests, a large resource creation request can be more safely split into multiple smaller memory allocation requests, thereby improving the success rate of memory allocation and avoiding other potential risks caused by splitting.

[0097] In this embodiment of the disclosure, the amount of video memory requested by any one of the at least two video memory allocation requests is less than or equal to a preset allocation threshold, and the sum of the amounts of video memory requested by the at least two video memory allocation requests is equal to the amount of video memory requested by the resource creation request.

[0098] Figure 2 This diagram illustrates how a resource creation request is mapped to multiple video memory allocation requests in a resource creation method provided in an embodiment of this disclosure. Figure 2 In the example shown, the target resource requested by the resource creation request is 64Mb in size. The user-mode driver can map this resource creation request into four memory allocation requests, each requesting 16Mb of memory, and each memory allocation request is responsible for mapping 16Mb of virtual address space to physical address space. Figure 2 The bottom of the diagram shows the physical memory layout, with gray areas representing occupied memory and white areas representing free memory. Four memory allocation requests are mapped to different locations in the physical memory, with each request responsible for 16MB of virtual address space. This mapping method allows the system to utilize free areas in the physical memory more flexibly, even if these areas are not contiguous.

[0099] In one possible implementation, the user-mode driver can map a resource creation request to at least two memory allocation requests in response to a resource creation request meeting a preset partitioning condition.

[0100] In one possible implementation, if the resource creation request does not meet the preset partitioning conditions, the user-mode driver can create a video memory allocation request based on the resource creation request.

[0101] In one possible implementation, the method further includes: for any one of the at least two memory allocation requests, determining the description information of the memory allocation request based on the characteristic information of the target resource and the memory request amount corresponding to the memory allocation request; the step of requesting memory allocation based on the at least two memory allocation requests includes: for any one of the at least two memory allocation requests, requesting memory allocation based on the description information of the memory allocation request.

[0102] In this implementation, each video memory allocation request can include descriptive information. The descriptive information of the video memory allocation request can be used to detail the specific needs of video memory allocation, so that the operating system or video memory manager can allocate video memory reasonably according to the descriptive information of the video memory allocation request.

[0103] In this implementation, the description information of the video memory allocation request may include the characteristic information of the target resource and the amount of video memory requested corresponding to the video memory allocation request.

[0104] As an example of this implementation, for any one of the at least two memory allocation requests, the user-mode driver can determine the description information of the memory allocation request based on the characteristic information of the target resource and the memory request amount corresponding to the memory allocation request. Furthermore, for any one of the at least two memory allocation requests, the user-mode driver can request memory allocation based on the description information of the memory allocation request.

[0105] In this implementation, memory allocation is requested based on the description information of the memory allocation request, which helps the memory manager better understand the needs of each memory allocation request, thereby completing the memory allocation more efficiently.

[0106] As an example of this implementation, the characteristic information of the target resource includes: the type of the target resource and / or the usage information of the target resource.

[0107] In one example, the characteristic information of the target resource may include the type of the target resource, such as texture, buffer, rendering target, etc.

[0108] In another example, the characteristic information of the target resource may include the purpose information of the target resource. For example, the purpose information of the target resource may be storing image data, storing vertex data, etc.

[0109] In this example, the target resource's characteristics (including type and / or usage information) provide crucial context for the video memory allocation system, helping it better understand resource requirements and application scenarios. Through this information, the video memory allocation system can allocate video memory more efficiently, improve allocation success rates, and optimize resource utilization.

[0110] As an example of this implementation, requesting video memory allocation based on the description information of the video memory allocation request includes: creating a handle corresponding to the video memory allocation request based on the description information of the video memory allocation request; and requesting video memory allocation based on the handle corresponding to the video memory allocation request.

[0111] A handle is an identifier used to uniquely identify a resource or request within the system. In video memory allocation, the handle's role includes uniquely identifying the memory allocation request and encapsulating request information. Specifically, the handle provides a unique identifier for each memory allocation request, facilitating system tracking and management of requests. Furthermore, the handle can encapsulate descriptive information about the memory allocation request, allowing the system to directly obtain the necessary information during subsequent allocation processes.

[0112] In one example, the PFND3DDDI_ALLOCATECB interface of the Direct3D Runtime can be called to create a handle corresponding to a memory allocation request. When creating the handle, description information can be stored in the handle, or the handle can be associated with description information. After creating the handle, a memory allocation request can be sent to the memory manager (such as the operating system or kernel-mode driver) through the handle.

[0113] In this example, encapsulating descriptive information through handles makes memory allocation requests more concise and efficient. Furthermore, the handle provides a unique identifier for each memory allocation request, facilitating system management and tracking.

[0114] In one possible implementation, the operating system's video memory manager can respond to video memory allocation requests and complete video memory allocation through a kernel-mode driver.

[0115] In one possible implementation, determining the amount of video memory requested corresponding to the resource creation request in response to the resource creation request includes: determining the amount of video memory requested corresponding to the resource creation request through a user-mode driver in response to the resource creation request; mapping the resource creation request to at least two video memory allocation requests in response to the resource creation request satisfying a preset partitioning condition includes: mapping the resource creation request to at least two video memory allocation requests through the user-mode driver in response to the resource creation request satisfying a preset partitioning condition; requesting video memory allocation based on the at least two video memory allocation requests to obtain at least two video memory allocation results corresponding to the at least two video memory allocation requests includes: requesting video memory allocation based on the at least two video memory allocation requests through the user-mode driver to obtain at least two video memory allocation results corresponding to the at least two video memory allocation requests; creating the target resource corresponding to the resource creation request based on the at least two video memory allocation results includes: creating the target resource corresponding to the resource creation request based on the at least two video memory allocation results through the user-mode driver.

[0116] In this implementation, the user-mode driver can handle processes such as responding to resource creation requests, determining whether preset partitioning conditions are met, splitting the resource creation request into multiple memory allocation requests, and creating the target resource based on the memory allocation results. Specifically, the user-mode driver can respond to a resource creation request, determine the amount of memory requested corresponding to the resource creation request, and if the resource creation request meets preset partitioning conditions, map the resource creation request to at least two memory allocation requests. Based on the at least two memory allocation requests, it requests memory allocation, obtains at least two memory allocation results corresponding to the at least two memory allocation requests, and creates the target resource corresponding to the resource creation request based on the at least two memory allocation results.

[0117] As an example of this implementation, the step of requesting video memory allocation based on the at least two video memory allocation requests by the user-mode driver and obtaining at least two video memory allocation results corresponding to the at least two video memory allocation requests includes: sending the at least two video memory allocation requests to the runtime through the user-mode driver; forwarding the at least two video memory allocation requests to the kernel-mode driver through the runtime; responding to the at least two video memory allocation requests by the kernel-mode driver and returning at least two video memory allocation results corresponding to the at least two video memory allocation requests to the runtime; and forwarding the at least two video memory allocation results to the user-mode driver through the runtime.

[0118] In this example, the runtime can be responsible for coordinating communication between the user-mode driver and the kernel-mode driver. The runtime can receive memory allocation requests sent by the user-mode driver and forward them to the kernel-mode driver.

[0119] Kernel-mode drivers run in the core layer of the operating system and have direct access to hardware resources. They can receive runtime-forwarded memory allocation requests and allocate memory based on the system's memory status (such as total memory size, allocated memory, and fragmentation). Kernel-mode drivers can attempt to find suitable memory space to satisfy each allocation request and generate the allocation result.

[0120] In this example, the user-mode driver handles resource management logic, the runtime handles communication coordination, and the kernel-mode driver handles hardware interaction. This division of labor makes the system more modular, easier to maintain, and easier to extend.

[0121] In one example, before determining the amount of video memory required for the resource creation request in response to the resource creation request by the user-mode driver, the method further includes: forwarding the resource creation request to the user-mode driver in response to the resource creation request from the application by the runtime; after creating the target resource corresponding to the resource creation request by the user-mode driver based on the at least two video memory allocation results, the method further includes: returning the target resource to the application by the runtime.

[0122] Figure 3 This diagram illustrates a resource creation method provided by an embodiment of the present disclosure. In step S1, an application (APP) may initiate a resource creation request. In step S2, a runtime (e.g., Direct3D Runtime) may, in response to the resource creation request from the application, forward the resource creation request to a user-mode driver (UMD). In step S3, the user-mode driver may, in response to the resource creation request, determine the amount of video memory requested corresponding to the resource creation request; in response to the resource creation request satisfying a preset partitioning condition, map the resource creation request to at least two video memory allocation requests; and send the at least two video memory allocation requests to the runtime. In step S4, the runtime may forward the at least two video memory allocation requests to the kernel-mode driver (DXGK (Display Graphics Kernel) and KMD (Kernel Mode Driver)). In step S5, the kernel-mode driver may, in response to the at least two video memory allocation requests, return at least two video memory allocation results corresponding to the at least two video memory allocation requests to the runtime. In step S6, the runtime may forward the at least two video memory allocation results to the user-mode driver. In step S7, the user-mode driver can create the target resource corresponding to the resource creation request based on the at least two video memory allocation results, and return the target resource to the runtime. In step S8, the runtime can return the target resource to the application.

[0123] The resource creation method provided in this disclosure can be applied to the technical fields of GPU, image rendering, video memory, etc., and is not limited thereto.

[0124] The resource creation method provided in this disclosure embodiment is illustrated below through a specific application scenario. Figure 4This diagram illustrates another resource creation method provided in an embodiment of the present disclosure. In this application scenario, an application can initiate a resource creation request. The user-mode driver can respond to the resource creation request by determining whether the resource creation request meets preset partitioning conditions.
