The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0067] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0068] The term "and / or" herein simply describes an association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can represent the existence of three situations: A alone, A and B simultaneously, and B alone.

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

[0070] An embodiment of the present disclosure provides a resource creation method, comprising: determining, in response to a resource creation request, a video memory request amount corresponding to the resource creation request; and mapping the resource creation request into at least two video memory allocation requests in response to the resource creation request satisfying a preset partitioning condition, wherein the preset partitioning condition at least includes: the video memory request amount corresponding to the resource creation request is greater than a preset allocation threshold; and the video memory request amount corresponding to any one of the at least two video memory allocation requests is less than or equal to the preset allocation threshold; requesting video memory allocation based on the at least two video memory allocation requests, obtaining at least two video memory allocation results corresponding to the at least two video memory allocation requests, and creating a target resource corresponding to the resource creation request based on the at least two video memory allocation results. Thus, when creating a resource, by mapping a resource creation request with a larger video memory request amount into at least two video memory allocation requests with smaller video memory request amounts, a success rate of video memory allocation can be improved, thereby improving the success rate of resource creation, thereby improving the stability of application operation, and increasing the number of applications running simultaneously under the same video memory resources.

[0071] The resource creation method provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

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

[0073] In step S11 , in response to a resource creation request, a video memory request amount 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 into at least two video memory allocation requests; wherein the preset partitioning condition includes at least: the video memory request amount corresponding to the resource creation request is greater than a preset allocation threshold; the video memory request amount 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, video memory allocation is requested according to the at least two video memory allocation requests, and at least two video memory allocation results corresponding to the at least two video memory allocation requests are obtained.

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

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

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

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

[0080] In a possible implementation, the target resource includes at least one type: a texture, a buffer, and a render target.

[0081] In this implementation, the type of resource may be a texture, a buffer, a render target, etc., which is not limited here.

[0082] In graphics rendering, a texture is a resource 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 a type of data storage resource. They can be used to store vertex data, index data, or other types of data that are used by the GPU during the rendering process. For example, the depth buffer can be used to store depth information to help determine which pixels should be rendered in front; constant buffers can be used to store data that does not change frequently, such as transformation matrices and lighting parameters; index buffers can be used to store vertex indices, which are used to determine which vertices make up a polygon; and so on.

[0084] A render target is a special buffer used to store the results of a rendering operation. For example, a frame buffer is a common render target that 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, where the characteristic information of the target resource may include the size of the target resource. For example, an app may need to create a 64MB texture resource to store image data.

[0086] In the embodiment of the present disclosure, the requested amount of video memory corresponding to the resource creation request may refer to the size of the video memory that needs to be allocated in order to satisfy the resource creation request.

[0087] In a possible implementation, the video memory request amount corresponding to the resource creation request may be determined according to the size of the target resource.

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

[0089] As another example of this implementation, the amount of graphics memory requested corresponding to the resource creation request may be slightly larger than the size of the target resource.

[0090] In a possible implementation, a user mode driver (UMD) may determine a requested amount of video memory corresponding to the resource creation request in response to the resource creation request.

[0091] In an embodiment of the present disclosure, in response to a resource creation request satisfying a preset partitioning condition, the resource creation request may be mapped into at least two video memory allocation requests. The preset partitioning condition may refer to a pre-set condition for determining whether to partition the resource creation request. Partitioning the resource creation request may refer to splitting a resource creation request with a larger video memory request into two or more video memory allocation requests with smaller video memory requests.

[0092] The preset division condition includes at least: the memory request amount corresponding to the resource creation request is greater than the preset allocation threshold. The preset allocation threshold can represent the upper limit of the memory request amount of the preset memory allocation request. For example, if the memory request amount corresponding to the resource creation request is A, the preset allocation threshold is t, and the resource creation request meets the preset division condition, then the resource creation request can be mapped to Video memory allocation requests, where Indicates rounding up.

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

[0094] As an example of this implementation, the preset division conditions also include: the target resource is a non-shared resource. A non-shared resource means that the resource is only used by one application or a specific context after creation, and will not be shared by multiple applications or multiple processes. In this case, the resource usage scenarios are relatively independent, so the resource creation request can be split into multiple small video memory allocation requests without worrying about shared access to resources between multiple users. For example, a texture resource in a game is only used by one scene and will not be shared by other scenes or modules. In this case, the resource creation request can be mapped to multiple video memory allocation requests.

[0095] As an example of this implementation, the preset division conditions also include: the target resource is not allowed to be modified by the CPU after creation. Among them, the resource is not allowed to be modified by the CPU after creation, which can mean that the resource is read-only to the CPU after creation, and its content will not be modified by the CPU during subsequent use. For non-modifiable resources, video memory allocation can be more flexible because there is no need to worry about subsequent modification operations affecting the integrity or consistency of the resources. 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 small allocation requests, thereby improving the success rate of video memory allocation.

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

[0097] In an embodiment of the present disclosure, the video memory request amount corresponding to 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 video memory request amounts corresponding to the at least two video memory allocation requests is equal to the video memory request amount corresponding to the resource creation request.

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

[0099] In a possible implementation, the user mode driver may map the resource creation request into at least two video memory allocation requests in response to the resource creation request satisfying a preset partitioning condition.

[0100] In a possible implementation, if the resource creation request does not meet the preset partitioning condition, the user mode driver may 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 video memory allocation requests, determining description information of the video memory allocation request based on characteristic information of the target resource and a video memory request amount corresponding to the video memory allocation request; requesting video memory allocation based on the at least two video memory allocation requests includes: for any one of the at least two video memory allocation requests, requesting video memory allocation based on the description information of the video memory allocation request.

[0102] In this implementation, each video memory allocation request may include description information, which may be used to describe specific requirements for video memory allocation so that an operating system or a video memory manager can allocate video memory appropriately based on the description information.

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

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

[0105] In this implementation, by requesting video memory allocation according to the description information of the video memory allocation request, the video memory manager can better understand the requirements of each video memory allocation request, thereby completing video 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 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 a texture, a buffer, a render target, and the like.

[0108] In another example, the characteristic information of the target resource may include usage information of the target resource, such as storing image data, storing vertex data, etc.

[0109] In this example, the target resource's characteristic information (including type and / or usage) provides important context for the memory allocation system, helping it better understand resource requirements and application scenarios. This characteristic information allows the memory allocation system to allocate memory more efficiently, improve allocation success rates, and optimize resource utilization.

[0110] As an example of this implementation, requesting video memory allocation according to the description information of the video memory allocation request includes: creating a handle corresponding to the video memory allocation request according to 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 that uniquely identifies a resource or request within the system. In video memory allocation, a handle can be used to uniquely identify a video memory allocation request and encapsulate request information. Specifically, a handle provides a unique identifier for each video memory allocation request, making it easier for the system to track and manage requests. Furthermore, a handle encapsulates the descriptive information of the video memory allocation request, allowing the system to directly access the required information during subsequent allocations.

[0112] In one example, the Direct3D Runtime's PFND3DDDI_ALLOCATECB interface can be called to create a handle corresponding to a video memory allocation request. When creating the handle, a description can be stored in the handle or associated with the handle. After the handle is created, the handle can be used to send a video memory allocation request to a video memory manager (e.g., an operating system (OS) or kernel-mode driver).

[0113] In this example, the handle encapsulates the description information, making the video memory allocation request more concise and efficient. In addition, the handle provides a unique identifier for each video memory allocation request, facilitating system management and tracking.

[0114] In a possible implementation, the video memory manager of the operating system may complete the video memory allocation through a kernel mode driver in response to the video memory allocation request.

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

[0116] In this implementation, a user-mode driver can complete processes such as responding to a resource creation request, determining whether a preset partitioning condition is satisfied, splitting the resource creation request into multiple video memory allocation requests, and creating a target resource based on the video memory allocation results. Specifically, the user-mode driver can, in response to a resource creation request, determine the video memory request amount corresponding to the resource creation request; in response to the resource creation request satisfying the preset partitioning condition, map the resource creation request into at least two video memory allocation requests; request video memory allocation based on the at least two video memory allocation requests; obtain at least two video memory allocation results corresponding to the at least two video memory allocation requests; and, based on the at least two video memory allocation results, create the target resource corresponding to the resource creation request.

[0117] As an example of this implementation, requesting video memory allocation according to the at least two video memory allocation requests by the user mode driver to obtain 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 by the user mode driver; forwarding the at least two video memory allocation requests to the kernel mode driver by the runtime; returning at least two video memory allocation results corresponding to the at least two video memory allocation requests to the runtime by the kernel mode driver in response to the at least two video memory allocation requests; and forwarding the at least two video memory allocation results to the user mode driver by the runtime.

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

[0119] Kernel-mode drivers run at the core of the operating system and have direct access to hardware resources. They receive memory allocation requests forwarded by the runtime and allocate memory based on the system's memory status (e.g., total memory, allocated memory, and fragmentation). They attempt to find appropriate memory space to satisfy each memory allocation request and generate a memory allocation result.

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

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

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