[0003] For some applications, the interface data of the application includes texture data.

Through texture data mapping, the texture data can be associated with the vertex data of the model so that it appears on the surface of the model during the rendering process. In other words, texture data is used to decorate the surface of an object. Texture data is like a sticker attached to the surface of an object, giving the surface of the object a pattern.

[0056] Dmabuf: Direct Memory Access Buffer (Dmabuf), a buffer sharing technology in the Linux kernel, solves the problem of buffer sharing between the CPU and various peripheral drivers.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0058] The embodiment of the present application provides a data display method, which is applied to a data display system, wherein the data display system includes a main operating system and a host operating system. The main operating system and the host operating system are loaded into a cockpit control chip 101, such as Figure 1As shown, the cockpit control chip 101 is respectively connected to the vehicle-mounted physical screen 103 and the memory 102, and the cockpit control chip 101 is loaded with the main operating system and the host operating system. The cockpit control chip 101 can be a SOC chip. Figure 2 As shown, the main operating system can be but not limited to the Linux operating system, and the host operating system can be but not limited to the Android operating system. Among them, the main operating system and the host operating system are divided into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the main operating system can be divided into four layers, namely, the application layer (applications), the framework layer (application framework), the hardware abstract layer (hardware abstract layer, HAL) and the kernel layer (kernel).
[0059] Among them, Figure 2 As shown, the main operating system can install instrument applications, intelligent control applications, etc. The instrument application can be used to display vehicle speed information, fuel information, vehicle acceleration information, etc. The intelligent control application can be used to display window control buttons, door control buttons, seat control buttons, etc. The main operating system also includes a graphics synthesizer, a virtual graphics processor backend Virtio-gpu backend, an OpenGL module, a graphics processing driver, and a Dmabuf module. The host operating system can install browser applications, navigation applications, etc. The host operating system also includes an OpenGL module, a virtual graphics processing driver, etc.
[0060] Specifically, Figure 3 As shown, the method provided in the embodiment of the present application includes:
[0061] S301 : When an application program running on a host operating system is triggered to open a first target interface, the host operating system transfers a texture data set of the application program to a first target storage address of the memory 102 .
[0062] Specifically, S301 can be implemented as follows:
[0063] Step 1: When an application running on the host operating system is triggered to open a first target interface, the virtual graphics processing front end of the host operating system applies to the memory 102 for a first target storage address for caching texture data of the application.
[0064] Step 2: The host operating system's open source graphics language port transfers the application's texture data set to the host operating system's virtual graphics processing front end.
[0065] Step 3: The virtual graphics processing front end of the host operating system transfers the texture data set of the application to the first target storage address of the memory 102 .
[0066] In some implementations, the glTexImage2D function may be used to transfer the application's texture data set to a first target storage address in the memory 102 .
[0067] For example, when the application of the host operating system is a navigation application, when the navigation application is triggered to open the initial interface, the texture data set of the navigation application can be transmitted to the first target storage address of the memory 102 based on the host operating system. Figure 4 As shown, the texture data set of the navigation application may include a navigation interface "positioning icon", "track icon" and "vehicle position icon", etc., which are not limited here.
[0068] The texture data set may include texture data corresponding to different interfaces of the navigation application.
[0069] S302: The host operating system transmits a first target storage address to the main operating system.
[0070] Specifically, the first target storage address may be transmitted to the virtual graphics processing backend of the main operating system based on the virtual graphics processing front end of the host operating system.
[0071] S303: When the application program running on the host operating system is triggered to open the second target interface, the host operating system transmits vertex data associated with the second target interface to the main operating system and transmits a data read instruction to the main operating system.
[0072] Specifically, the vertex data associated with the second target interface may be transmitted to the virtual graphics processing backend of the main operating system based on the virtual graphics processing front end of the host operating system, and a data reading instruction may be transmitted to the main operating system.
[0073] For example, when the application is a navigation application, the second target interface may be the navigation interface of the navigation application. Optionally, the first target interface and the second target interface are the same interface or different interfaces. For example, when the second target interface is the navigation interface of the navigation application, the first target interface may also be the navigation interface of the navigation application, in which case the first target interface and the second target interface are the same interface. For another example, when the second target interface is the navigation interface of the navigation application, the first target interface may also be the homepage of the navigation application, in which case the first target interface and the second target interface are not the same interface.
[0074] S304: The main operating system responds to the data read instruction and reads texture data associated with the second target interface from the texture data set based on the first target storage address.
[0075] When the second target interface may be a navigation interface of a navigation application, the texture data associated with the navigation interface may be read from a texture data set corresponding to a plurality of interfaces of the navigation application.
[0076] S305: Rendering interface data of the second target interface in the main operating system according to the texture data and vertex data associated with the second target interface.
[0077] For example, the texture data is associated with a display position and a display size, and the interface data of the second target interface can be rendered in the main operating system according to the display position, the display size, and the texture data and vertex data associated with the second target interface.
[0078] S306: The main operating system transmits the interface data of the second target interface to the vehicle-mounted physical screen 103 for display.
[0079] In summary, an embodiment of the present application provides a data display method, when an application running on a host operating system is triggered to open a first target interface, the host operating system transfers the texture data set of the application to the first target storage address of the memory 102, and the host operating system transfers the first target storage address to the main operating system; when an application running on the host operating system is triggered to open a second target interface, the host operating system transfers vertex data associated with the second target interface to the main operating system and transfers a data read instruction to the main operating system; the main operating system responds to the data read instruction, and the first target storage address reads the texture data associated with the second target interface from the texture data set. In this way, the main operating system and the host operating system can share a first target storage address for caching texture data, thereby saving storage space.
[0080] Optionally, in some embodiments, Figure 4 As shown, S302 can be specifically implemented as follows:
[0081] S3021: The virtual graphics processing front end of the host operating system sends a first target storage address to the virtual graphics processing back end of the main operating system.
[0082] S3022: Transmit the first target storage address from the virtual graphics processing backend to the dmabuf module of the main operating system.
[0083] S3023: The dmabuf module converts the first target storage address into a first address identifier, and transmits the first address identifier back to the virtual graphics processing backend.
[0084] Based on the above S3021-S3023, it can be known that the main operating system can convert the first target storage address storing the texture data into the first address identifier without allocating a new memory 102 area for the texture data, thereby saving storage space.
[0085] Further, in Figure 4 Based on the corresponding embodiment, S304 may include:
[0086] S3041: The virtual graphics processing backend of the main operating system transmits the first address identifier to the image processing driver of the main operating system in response to the data read instruction.
[0087] S3042 : The image processing driver and the first address identifier of the main operating system read texture data associated with the second target interface from the texture data set at the first target storage address of the memory 102 .
[0088] In this way, it is possible to accurately read the texture data associated with the second target interface in the texture data set only with the first address identifier.
[0089] In some implementations, similar to the transmission of texture data associated with the second target interface from the host operating system to the main operating system, the transmission of vertex data associated with the second target interface from the host operating system to the main operating system includes:
[0090] Step A: The host operating system transmits the vertex data associated with the second target interface to the second target storage address of the memory 102 .
[0091] Step B: The host operating system transmits the second target storage address to the virtual graphics processing backend of the main operating system.
[0092] Step C: In the main operating system, the second target storage address is transmitted from the virtual graphics processing backend to the dmabuf module of the main operating system.
[0093] Step D: In the main operating system, the dmabuf module converts the second target storage address into a second address identifier, and transmits the second address identifier back to the virtual graphics processing backend.
[0094] Step E: In the main operating system, the second address identifier is transmitted to an image processing driver of the main operating system.
[0095] Step F: The image processing driver of the main operating system and the second address identifier read the vertex data associated with the second target interface from the texture data set located at the second target storage address of the memory 102 .
[0096] Based on the above steps A to F, the transmission of the vertex data associated with the second target interface can be achieved without allocating additional storage space for the vertex data associated with the second target interface in the memory 102, thereby further saving storage resources.
[0097] The embodiment of the present application also provides a data display system, including a main operating system and a host operating system, wherein:
[0098] The host operating system is used to transfer the texture data set of the application to the first target storage address of the memory when the first target interface of the application running on the host operating system is opened, wherein the first target interface requires GPU processing;
