Detailed Description
The technical solution of the present application is further described in detail with reference to the drawings and specific embodiments of the specification.
Fig. 1 is a schematic view of a first flow implementation of the processing method in the present application, as shown in fig. 1, the method includes:
here, the method is mainly applied to an electronic device, which may be a personal computer, a workstation, a game machine, a tablet computer, a smart phone, and the like. A graphics processor, i.e., a GPU chip, is mounted on the motherboard of the electronic device, and the GPU chip can process image and graphics related arithmetic operations.
In this application, in the process of performing power-on initialization on the graphics processor, the system firmware or the bios on the electronic device may obtain attribute information of the graphics processor, and may determine whether the graphics processor supports a single mode or multiple modes according to the attribute information. When the system firmware or the basic input output system determines that the graphics processor supports multiple modes based on the attribute information of the graphics processor, system resources are configured for the graphics processor based on a preset resource parameter requirement table.
Here, the system Firmware (FW) or Basic Input Output System (BIOS) configures system resources for the graphics processor to meet system resource requirements of the graphics processor in different modes.
For example, when a graphics processor on an electronic device supports both a graphics mode and a computing mode, the system firmware or bios configures or reserves system resources for the graphics processor, which can meet system resource requirements of the graphics processor in the graphics mode and can also meet system resource requirements of the computing mode. Therefore, the system resources which can meet the system resource requirements of the graphics processor in different modes are configured for the graphics processor, so that the graphics processor can conveniently use the target system resources without electrifying and initializing the graphics processor again when the modes of the graphics processor are switched, and the working efficiency of the electronic equipment can be improved.
In this application, before configuring system resources for the graphics processor, the electronic device may further determine system resource requirements of the graphics processor in different modes according to system resource information input by a developer for the graphics processor, and may obtain the resource parameter requirement table by performing integration processing on the system resource requirements of the graphics processor in each mode. Here, the resource parameter requirement table stores information that satisfies system resource requirements of the graphics processor in different modes.
In this application, in order to avoid waste of system resources, if the preset resource parameter table has overlapping resources, the electronic device may further perform deduplication processing on the overlapping resources, so that the configured system resources are not overlapped when the electronic device configures the system resources for the graphics processor. Therefore, the graphics processor can be guaranteed to have enough system resources, and waste of the system resources can be avoided.
Here, the target system resource given to the operating system is specifically a system resource required when the image processor switches to the target mode.
For example, when the graphics processor is in graphics mode, when the graphics processor switches from graphics mode to compute mode, the FW or BIOS updates the system resources needed by the graphics processor in compute mode to the operating system so that the operating system accesses the graphics processor based on the system resources, and the graphics processor can operate in the updated system resources environment.
In this application, the mode of the graphics processor is usually switched only when the graphics processor satisfies the mode switching condition.
For example, when the user performs a mode switching operation on the graphics processor, a System Management Interrupt (SMI) event is triggered, and when the electronic device detects the SMI event, the graphics processor is characterized to satisfy a mode switching condition. Or, when the electronic device enables an application program, the electronic device may acquire hardware resources and/or software resources required by the application program, and if the hardware resources and/or software resources fail to match system resources in the current mode of the graphics processor and successfully match performance parameters in another mode of the graphics processor, an SMI event may be triggered, and when the electronic device detects the SMI event, it may indicate that the graphics processor satisfies a mode switching condition.
For example, a game application is enabled by the current electronic device, the electronic device matches the resources required by the game application with the system resources that can be invoked in the current mode (e.g., graphics mode) of the graphics processor, if the matching fails, indicating that the game application requires more powerful general-purpose computing power or rendering capability, such as supporting collision detection, approximate physical simulation, etc., a SIM event is triggered, and the electronic device detects the SIM event and performs mode switching on the graphics processor.
In the present application, when the SMI event is triggered, the CPU may enter a System Management Mode (SMM), and in the SMM mode, the BIOS has the highest authority to manage System resources. Therefore, after the CPU enters the SMM mode, the BIOS may configure target system resources for the image processor in the target mode in the SMM mode, and meanwhile, the mode switch program corresponding to the BIOS updates the target system resources allocated by the BIOS for the image processor to the FW or BIOS, and reports the target system resources allocated by the image processor to the operating system of the electronic device, so that the operating system updates the current system resource list based on the target system resources. The CPU then exits the SMM mode, at which point the mode switching operation characterizing the image processor is complete.
In this application, before the graphics processor performs mode switching, the electronic device may further obtain a current mode parameter value of the graphics processor through a mode switching interface of the graphics processor; based on the mode parameter value, a current mode of the graphics processor is determined.
Here, the mode switching interface may be an interface defined by an application corresponding to the current operating system and the FW or BIOS, and when the mode of the graphics processor needs to be switched, the FW or BIOS may be notified of the mode switching of the graphics processor through the mode switching interface.
For example, when the current mode parameter value of the graphics processor is "1" through the mode switching interface of the graphics processor, the current mode characterizing the graphics processor is the graphics mode. When the current mode parameter value of the graphics processor is acquired to be '0' through the mode switching interface of the graphics processor, the current mode representing the graphics processor is a calculation mode.
In this application, when the electronic device determines that the current mode of the graphics processor (referred to as a mode before mode switching) is set, the system resources used by the graphics processor in the current mode may also be reported to an operating system of the electronic device, so that the operating system can use the system resources in the current mode at least after mode switching.
For example, the graphics processor uses an input/output (I/O) interface in a current mode (e.g., graphics mode), and the I/O interface is also used in a switched mode (e.g., compute mode) after the graphics processor switches modes, so that the operating system can directly use the system resources of the I/O interface of the graphics processor in the graphics mode when the graphics processor switches modes.
Or, the graphics processor uses the camera function in the current mode (e.g., graphics mode), and the graphics processor uses the camera function in the switched mode (e.g., computing mode) after switching the modes, so that the operating system does not shut down the system resource, which is the camera function of the graphics processor in the graphics mode, when the graphics processor switches the modes, thereby further improving the response speed of the electronic device.
In this application, the electronic device may also configure target system resources for the graphics processor.
For example, a system management interrupt event may be triggered during the process of the graphics processor switching from a computing mode to a graphics mode, at which time a central processing unit on the electronic device may enter an SMM mode, in which system firmware or a bios on the electronic device may configure a first target system resource for the graphics processor; and after configuring the first target system resource for the graphics processor, updating the first target system resource to an operating system of the electronic device, so that the operating system can access the graphics processor or update system resource information different from the first target system resource in a current system resource table based on the first target system resource.
Alternatively, a system management interrupt event may be triggered during the process of the graphics processor switching from graphics mode to computing mode, at which point the central processing unit on the electronic device may enter SMM mode, in which the system firmware or bios on the electronic device may configure second target system resources for the graphics processor. And after configuring a second target system resource for the graphics processor, the second target system resource may be updated to an operating system of the electronic device, so that the operating system can access the graphics processor or update system resource information different from the second target system resource in a current system resource table based on the second target system resource.
Here, the first target system resource is at least partially different from the second target system resource.
For example, the system resources used in the computing mode include: 8GB memory, 3D controller, I/O interface; the system resources used in the graphics mode include: 256MB memory, VGA controller and I/O interface. The same system resource of the computing mode and the graphic mode is an I/O interface, and the different system resource is a memory and a controller. When the BIOS sends system resources in the compute mode to the operating system, the operating system may only update memory and controller resources in the current system resource table because the "I/O interface" resources in the compute mode and the graphics mode are the same. Thus, the mode switching speed of the graphics processor can be increased, and the response speed of the operating system can be increased.
Fig. 2 is a schematic view of a second implementation flow of the processing method in the present application, as shown in fig. 2, including:
in step 202, the BIOS configures system resources for the GPU.
Here, the system resources configured by the BIOS for the GPU can meet the system resource requirements of the GPU in different modes. Therefore, the GPU can conveniently acquire the target system resources without being powered on again and initialized during mode switching.
Here, the electronic device may obtain a current mode parameter value of the GPU through a mode switching interface predetermined by the GPU and the BIOS, and if the mode parameter value is "1", the current operating mode representing the GPU is a computing mode, configure a system resource for the GPU in the computing mode, and report the system resource configured by the GPU in the computing mode to the OS, so that the OS accesses the GPU in the computing mode after updating the current system resource list based on the system resource. Thereby enabling the GPU to be used normally in a resource environment in a compute mode. If the mode parameter value is "0", the current working mode of the GPU is characterized as the graphic mode, system resources are configured for the GPU in the graphic mode, and the system resources configured when the GPU is in the graphic mode are reported to the OS, so that the OS accesses the GPU in the graphic mode after updating the current system resource list based on the system resources. Thereby enabling the GPU to be used normally in a resource environment in graphics mode.
And step 204, triggering SMI when the GPU mode is switched.
Here, when the user performs mode switching on the GPU, the mode switching interface defined by the GPU and the FW/BIOS may trigger an SMI to notify the FW/BIOS that the GPU is to perform mode switching.
In step 205, the CPU enters SMM mode.
Here, SMM is a special mode of operation that is not dependent on a specific operating system, being controlled entirely by firmware. SMM mode can only be entered by a system management interrupt SMI instruction and can only be exited by the execution of an RSM instruction. When the CPU detects an SMI event or instruction, SMM mode is entered because the BIOS has the highest authority to manage system resources in SMM mode.
In step 206, the BIOS switches modes of the GPU, and updates the target system resources configured by the GPU after the mode switching to the resource list of the OS.
Here, after the CPU enters the SMM mode, the BIOS switches the current mode of the GPU in the SMM mode, and configures target system resources for the GPU after the mode switching based on the system resources reserved for the GPU. After the target system resources are configured for the GPU after mode switching, the target system resources allocated by the GPU are updated to FW/BIOS through a mode switching program corresponding to the BIOS and are reported to a resource list of the OS, and therefore the OS can access the GPU after mode switching based on the target system resources so as to enable the GPU to reach an optimal state in a resource environment after mode switching.
Here, after the BIOS configures the target system resource for the GPU after the mode switching and reports the target system resource configured by the GPU after the mode switching to the OS, the CPU detects a system resume instruction (RSM) to exit the SMM mode, at which point, it indicates that the GPU mode switching is completed.
Under the condition that hardware cost is not increased, when the GPU is electrified and initialized, system resources of the GPU in different modes can be met by configuring the GPU through the BIOS or the FW, so that the GPU can be freely switched among multiple modes, a user can shuttle among different application programs at will, the user does not need to restart a machine to realize mode switching every time the GPU is switched, but resource configuration is carried out on the GPU after mode switching based on system resources reserved for the GPU by the BIOS, product competitiveness is improved, and working efficiency of the user and mode switching efficiency of the GPU are greatly improved.
