Detailed Description
The technical scheme of the application is further elaborated below by referring to the drawings in the specification and the specific embodiments.
Fig. 1 is a schematic diagram of a process implementation of a processing method according to the present application, as shown in fig. 1, where the method includes:
step 101, configuring system resources for a graphic processor, wherein the system resources can meet the system resource requirements of the graphic processor in different modes;
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, or the like. A graphic processor, namely a GPU chip, is arranged on a main board of the electronic equipment, and the GPU chip can process image and graphic related operation work.
In the application, the system firmware or the basic input/output system on the electronic equipment can acquire the attribute information of the graphic processor in the process of powering on and initializing the graphic processor, and can determine whether the graphic 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 demand table.
Here, the system Firmware (FW) or Basic Input Output System (BIOS) configures system resources for the graphics processor, so as to satisfy the 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 satisfy both the system resource requirements of the graphics processor in the graphics mode and the system resource requirements in the computing mode. Therefore, by configuring the system resources for the graphic processor, the system resources which can meet the system resource requirements of the graphic processor in different modes can be conveniently used for target system resources without re-powering on initialization of the graphic processor when the graphic processor is switched in modes, so that the working efficiency of the electronic equipment can be improved.
Before configuring system resources for the graphic processor, the electronic device can also determine the system resource requirements of the graphic processor in different modes according to the system resource information input by a developer for the graphic processor, and the resource parameter requirement table can be obtained by integrating the system resource requirements of the graphic processor in each mode. Here, the resource parameter demand table stores therein system resource demand information satisfying different modes of the graphics processor.
In the application, in order to avoid the waste of system resources, if the preset resource parameter table has overlapped resources, the electronic equipment can also perform de-duplication processing on the overlapped resources, so that the configured system resources cannot be overlapped when the electronic equipment configures the system resources for the graphic processor. Thus, the graphics processor can be ensured to have enough system resource usage, and the waste of the system resource can not be caused.
And 102, updating the system firmware or the target system resources configured by the basic input/output system for the graphic processor to an operating system when the graphic processor performs mode switching, so that the graphic processor operates in an updated system resource environment.
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 image processor is switched from the graphics mode to the computing mode, the FW or BIOS updates the system resources required by the image processor in the computing mode to the operating system so that the operating system accesses the image processor based on the system resources, and the image processor can operate in the updated system resource environment.
In the present application, the mode switching is typically performed on the graphics processor when the graphics processor satisfies the mode switching condition.
For example, when a user performs a mode switch operation with respect to the graphics processor, a system management Interrupt event (SMI, system Management Interrupt) is triggered, and when the electronic device detects the SMI event, the graphics processor is characterized as meeting a mode switch condition. Or when the electronic device starts a certain application program, the electronic device can acquire the hardware resource and/or the software resource required by the application program, if the hardware resource and/or the software resource fails to be matched with the system resource in the current mode of the graphic processor and is successfully matched with the performance parameter in the other mode of the graphic processor, an SMI event can be triggered, and when the electronic device detects the SMI event, the graphic processor is characterized to meet the mode switching condition.
For example, current electronic devices enable a game application that matches the resources required by the game application with system resources that can be invoked in the current mode of the graphics processor (e.g., graphics mode), and if the match fails, indicating that the game application requires more general purpose computing power or rendering power, such as supporting collision detection, near physical simulation, etc., a SIM event is triggered, and the electronic device detects the SIM event and then mode switches the graphics processor.
In the application, when the SMI event is triggered, the CPU enters a system management Mode (SMM, system Management Mode), 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 a target system resource for the image processor in the target mode in the SMM mode, and at the same time, the mode switching program corresponding to the BIOS updates the target system resource allocated by the BIOS for the graphics processor to FW or BIOS, and reports the target system resource allocated by the graphics 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 resource. The CPU then exits the SMM mode, at which point the mode switch operation characterizing the image processor is complete.
Before the mode switching of the graphic processor, the electronic equipment can also acquire the current mode parameter value of the graphic processor through the mode switching interface of the graphic 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 FW or BIOS, and when the graphics processor needs to be mode switched, the FW or BIOS may be notified through the mode switching interface that the graphics processor needs to be mode switched.
For example, when the current mode parameter value of the graphics processor is "1" acquired through the mode switching interface of the graphics processor, the current mode of the graphics processor is characterized as a graphics mode. When the current mode parameter value of the graphics processor is '0' through the mode switching interface of the graphics processor, the current mode of the graphics processor is characterized as a calculation mode.
In the application, when the electronic equipment determines the current mode (the mode before mode switching) of the graphic processor, the system resources used by the graphic processor in the current mode can be reported to the operating system of the electronic equipment, so that the operating system can at least use the system resources in the current mode after the mode switching.
For example, the graphics processor uses an input/output (I/O) interface in a current mode (e.g., graphics mode), and after the graphics processor performs mode switching, the graphics processor also uses the I/O interface in a switched mode (e.g., computing mode), so that the operating system can directly use the system resource, I/O interface, of the graphics processor in the graphics mode when the graphics processor performs mode switching.
Or the image processor uses the camera function in the current mode (such as the image mode), and after the image processor performs the mode switching, the image processor also uses the camera function in the switched mode (such as the calculation mode), so that the operating system can not shut down the system resource of the camera function of the image processor in the image mode when the image processor performs the mode switching, and the response speed of the electronic equipment can be further improved.
In the application, the electronic equipment can also configure target system resources for the graphic processor.
For example, during a transition of the graphics processor from a computing mode to a graphics mode, a system management interrupt event may be triggered, at which time a central processor on the electronic device may enter a SMM mode in which system firmware or a basic input output system 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 to enable the operating system to access the graphics processor or update system resource information in a current system resource table that is different from the first target system resource based on the first target system resource.
Or during the process of the graphics processor switching from the graphics mode to the computing mode, a system management interrupt event may be triggered, at which time the central processor on the electronic device may enter the SMM mode, in which system firmware or a basic input output system on the electronic device may configure a second target system resource for the graphics processor. And after configuring the second target system resource for the graphics processor, the second target system resource may also be updated to an operating system of the electronic device to enable the operating system to access the graphics processor or update system resource information in a current system resource table that is different from the second target system resource 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 of memory, VGA controller, I/O interface. Wherein the same system resource for the compute mode and the graphics mode is an "I/O interface" and the different system resources are "memory and controller". When the BIOS sends system resources in computing mode to the operating system, the operating system may only update the memory and controller resources in the current system resource table because the "I/O interface" resources in computing mode and graphics mode are the same. Thus, not only the mode switching speed of the graphics processor but also the response speed of the operating system can be improved.
Fig. 2 is a schematic diagram of a second implementation of the flow of the processing method in the present application, as shown in fig. 2, including:
Step 201, initializing a system;
in step 202, BIOS configures system resources for the GPU.
Here, the BIOS configures the system resource for the GPU to be capable of meeting the system resource requirement of the GPU in different modes. Therefore, the GPU can conveniently acquire the target system resources without re-powering up initialization during mode switching.
Step 203, determining the current working mode of the GPU, and reporting the system resources used by the GPU in the current mode to the OS.
Here, the electronic device may obtain, through a mode switching interface predetermined by the GPU and the BIOS, a current mode parameter value of the GPU, and if the mode parameter value is "1", characterize that a current working mode of the GPU is a computing mode, configure system resources for the GPU in the computing mode, and report the system resources configured by the GPU in the computing mode to the OS, so that the OS accesses the GPU in the computing mode after updating a current system resource list based on the system resources. Therefore, the GPU can be normally used in a resource environment in a computing mode. If the mode parameter value is 0, the current working mode of the GPU is represented as a graphic mode, system resources are configured for the GPU in the graphic mode, and the system resources configured by the GPU 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. Therefore, the GPU can be normally used in a resource environment in a graphics mode.
In step 204, when the gpu mode is switched, the SMI is triggered.
Here, when the user performs mode switching on the GPU, the SMI may be triggered through the mode switching interface defined by the GPU and FW/BIOS to inform 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 the specific operating system, and is entirely controlled by firmware. The SMM mode can only be entered by system management interrupt SMI instructions and can only be exited by execution of RSM instructions. When the CPU detects an SMI event or instruction, the SMM mode is entered because in the SMM mode the BIOS has the highest authority to manage system resources.
In step 206, the BIOS performs mode switching on the GPU, and updates the target system resources configured by the GPU after mode switching into the resource list of the OS.
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 the mode switching, updating the target system resources allocated to the GPU to FW/BIOS and reporting to a resource list of the OS through a mode switching program corresponding to the BIOS, so that the OS can access the GPU after the mode switching based on the target system resources to enable the GPU to reach an optimal state in a resource environment after the mode switching.
In step 207, the cpu exits the SMM mode and the GPU mode switching is completed.
Here, after the BIOS finishes configuring the target system resource for the GPU after the mode switching, and reports the target system resource configured for the GPU after the mode switching to the OS, the CPU detects a system resume instruction (RSM) to exit the SMM mode, and at this time, characterizes that the GPU mode switching is completed.
Under the condition of no hardware cost increase, the system resources of the GPU in different modes can be met by configuring the GPU for the BIOS or FW when the GPU is electrified and initialized, so that the GPU can be freely switched among various modes, a user can also freely shuttle among different application programs, the machine is not required to be restarted for realizing the mode switching of the GPU each time, and the resource configuration is carried out on the GPU after the mode switching based on the system resources reserved by the BIOS for the GPU, thereby not only improving the product competitiveness, but also greatly improving the working efficiency of the user and the mode switching efficiency of the GPU.
