The BIOS main function is to provide the lowest, most direct hardware setup and control for the computer. The interfaces provided by the BIOS to the operating system include BS (Boot Services) and RT (run time Services).
Display card BIOS: the BIOS is also called VGA BIOS or Video BIOS, and is mainly used for storing a control program between the display chip and the driver program, and controlling various working states of the display card, including core working frequency, video memory working frequency, power consumption limit, working voltage, video memory time sequence and other core parameters. The display card BIOS chip is used for storing the display card BIOS program, and the display card BIOS is stored in the BIOS chip, like the main board BIOS, but not in the disk.
NVAPI: NVAPI an interface for third party invocation provided by NVIDIA (inflight/huida) manufacturers is used to monitor the temperature, performance parameters etc. of the graphics card.
ACPI: advanced Configuration and Power Interface, advanced configuration and power interface, ACPI is an interface between system hardware/firmware (BIOS) and OS (operating system) and OS applications. In other words, the BIOS provides operating system to hardware communication through a unified interface, and ACPI is one implementation of such a unified interface in the BIOS. ACPI provides two types of data structures for the Operating System (OS): data tables and definition blocks. They are interfaces for the OS (operating system) to interact with BIOS/EFI firmware. The data table stores raw data and is used by the device driver. The definition block is made up of bytecodes executable by an interpreter. The data table portion of which is responsible for generation by firmware (BIOS/EFI) for information describing various aspects of the system hardware. The ACPI interface contains a number of predefined tables whose definitions are stored in the BIOS chip, generated by the BIOS into memory, and submitted to the operating system.
ACPI Control Method: ACPI control methods, like functions in the C language, the function of AML is called Method. According to the ACPI specification, the BIOS provides some standard Method for OS calls, such as_PTS, _WAK, etc. The control method defines how the OS performs a simple hardware task. For example, the OS invokes the control method (ControlMethod) to read the temperature of a high-temperature zone.
WMI: windows management instrumentation, windows management Specification, provides a unified interface to any local or remote application or script that obtains management data from a computer system, network, or enterprise. The unified interface design eliminates the need for WMI client applications and scripts to invoke a variety of operating system Application Programming Interfaces (APIs).
NVIDIADYNAMIC BOOST (dynamic enhancement): the method is a new technology, and can more intelligently distribute power for the CPU and the GPU of the notebook computer, so that the power consumption utilization efficiency of the notebook computer is improved on the premise of limited power consumption, and the overall performance of the notebook computer is improved.
Dx-Notify: the performance control interface reserved by the NVIDIA (Inlet Weida) display card supports the performance control of 5 steps of D1-D5, the GPU performance corresponding to each step is different, the performance corresponding to D1-D5 can be set in the Video BIOS, the D1 performance is the strongest, and the D5 performance is the weakest.
SCI: system Control Interrupt, system control interrupts. One IRQ (interrupt request), dedicated to ACPI power management, requires OS (operating system) support.
SMI: SYSTEM MANAGEMENT Interrupt, system management Interrupt, special Interrupt to enter SMM (SYSTEM MANAGEMENT Mode ) using system.
SMM: SYSTEM MANAGEMENT Mode, system management Mode, which is a standard architectural feature that is unified for all Intel processors, provides the same execution environment as a System Management Interrupt (SMI) handler in the traditional IA-32 architecture.
TGP: total Graphics Power, generally refers to the performance/power consumption of the entire graphics card.
TDP: CPU THERMAL DESIGN Power, heat dissipation design Power consumption, meaning "when the processor reaches maximum load, the released heat" (unit is W), is an index reflecting the heat release of a processor, and TDP is an index reflecting the heat release of the processor, and is the maximum heat limit that the cooling system of the computer must have the capability to dissipate.
TPP power consumption: total Processor Power, full processor power consumption, for notebooks, generally refers to CPU power consumption+gpu power consumption.
DB Power consumption: the dynamic power consumption of the display card, namely, the upper limit and the lower limit of the dynamic adjustment on the TGP power consumption of the display card, for example, the TGP power consumption is 40W, the DB power consumption is 15W, and the display card driving can limit the display card power consumption to between 25W and 55W according to the current power consumption/actual power consumption of the CPU.
Single/double baking: the baking machine is a stability test of a computer, the single baking is a pressure test of independently running a certain component by software (such as AIDA64 Extreme), for example, the single baking of a GPU and an FPU is realized by the software, and the double baking is realized by the software, so that the two tests are simultaneously carried out, and the full load work of the CPU and the GPU is generally indicated.
Address information: the CPU/program can acquire the specific position of the pre-applied memory through the address information, and store parameters such as GPU temperature, CPU temperature, mainboard temperature, fan rotation speed and the like in the memory, and the address information can be the starting position and length of the memory, the starting position and the last position of the memory, and any address information which can be used for representing the position of the memory is applicable to the embodiment of the application.
A focus window (focus window) refers to a window having focus. The focus window is the only window that can receive keyboard input. The manner in which the focus window is determined is associated with the focus mode (focus mode) of the system. The top level window of the focus window is called an active window (active window). Only one window at a time may be an active window. The focus window is a window which is needed to be used by the user at present with high probability.
The focus mode may be used to determine how the mouse brings a window into focus. In general, the focus modes may include three types, respectively:
(1) Click-to-focus (click-to-focus) in this mode, the window that the mouse clicks on gets focus. I.e. when the mouse clicks on any position of a window where focus is available, the window is activated, placed in front of all windows and receives keyboard input. When the mouse clicks on other windows, the window loses focus.
(2) The focus follows the mouse (focus-mouse), in which mode a window under the mouse can acquire focus. I.e. when the mouse is moved to a range of windows where focus is available, the user does not need to click somewhere on the window to activate the window, receive keyboard input, but the window is not necessarily placed at the forefront of all windows. When the mouse moves out of the range of this window, this window will also lose focus.
(3) Grass focus (sloppy focus), this focus mode is relatively similar to focus-mouse: when the mouse is moved to a window where focus is available, the user may activate the window without clicking somewhere on the window, receiving keyboard input, but the window is not necessarily positioned at the forefront of all windows. Unlike focus-focus, focus does not change when the mouse moves out of this window, but only when the mouse moves into another window that can receive focus.
A process includes multiple threads, which may create a window. The focus process is the process to which the thread that created the focus window belongs.
Among all chips or processors of a notebook computer or a portable computer (Laptop), a CPU (central processing unit) and a GPU (graphics processing unit) are chips with the largest power consumption and the most difficult performance to control, and how to control the performance, the power consumption and the heat of the CPU and the GPU.
FIG. 1 is a schematic diagram illustrating the modular interaction of one present performance tuning methodology. In the example shown in fig. 1, the current graphics card performance adjustment procedure is illustrated by adjusting the Dx value (i.e., the Dx value in Dx-Notify) of the NV (i.e., NVIDIA) graphics card.
In the present application, a graphics card, GPU, graphics processing unit or graphics processor have the same meaning, representing the same components in the device. The graphic cards may be divided into integrated graphic cards and independent graphic cards. In the embodiment of the application, the performance of the independent display card is regulated by taking an example as an explanation. However, it should be understood that the performance adjustment method disclosed in the embodiment of the present application is also applicable to an integrated graphics card. In addition, in the embodiment of the present application, an NV video card is taken as an example for illustration, but the performance adjustment and control method disclosed in the embodiment of the present application is also applicable to other video cards.
As shown in fig. 1, the current method for adjusting and controlling the performance of a graphics card of an electronic device includes:
S101, a controller (EC) reads the temperature of the display card from a temperature sensor outside the display card.
Illustratively, a controller (EC) is communicatively coupled to a temperature sensor external to the graphics card via, for example, a system management bus ("SMBus") and polls the temperature sensor or other device via the system management bus ("SMBus") to read the unique graphics card temperature from the temperature sensor external to the graphics card.
S102, a controller (EC) determines the Dx value of the display card according to the temperature of the display card.
And the controller determines the current Dx value of the display card based on the current temperature of the display card according to the relation between the preset temperature and the Dx value. For example, when the current temperature of the display card exceeds the upper limit temperature corresponding to D4, the controller (EC) determines to adjust the value Dx of the display card to D5, so as to reduce the performance of the display card, thereby reducing the temperature of the display card.
S103, the controller (EC) informs the BIOS to switch the Dx value of the display card.
Illustratively, the controller (EC) communicates data through 62/66IO ports. The BIOS and controller (EC) pre-define the SMI (SYSTEM MANAGEMENT Interrupt) Interrupt number, and the BIOS or more specifically the BIOS runtime services obtain the Interrupt number from the controller (EC) through the 62/66IO port. SCI interrupt is generated after the controller (EC) determines the Dx value of the display card, and the interrupt service function corresponding to the service call interrupt number is read out from the Dx value of the display card through the 62/66IO port again when the BIOS operates.
S104, the BIOS modifies the Dx value and informs the display card driver to read the Dx value.
Illustratively, a storage location in the ACPI where the Dx value is stored is specified in the internal memory (i.e., the memory), and after the BIOS reads the Dx value, the BIOS modifies the Dx value of the storage location to the latest value, and then notifies the graphics card driver to read the latest Dx value.
S105, the display card drives and reads the Dx value, and the display card is controlled according to the power consumption corresponding to the Dx value.
Specifically, the BIOS generates a SCI interrupt after modifying the Dx value, and the display card driver invokes a display card control method (ACPI) to read the current value of Dx after receiving the SCI interrupt (i.e. event notification).
And after the current value of Dx is read, controlling the performance of the display card according to the power consumption corresponding to the current value of Dx. For example, when the current Dx value is D3 and the power consumption of the corresponding graphics card is 15W, the graphics card driving controls the graphics card to limit the maximum power consumption to 15W.
The specific power consumption corresponding to the current value of Dx can be obtained from the graphics card BIOS.
Although the display card performance can be regulated and controlled by the display card performance regulating method, the display card performance can be passively controlled only according to the temperature of the display card, and the display card performance can not be actively controlled according to the scene and the requirement, in many cases, the performance can be regulated and controlled only after the temperature of equipment or the display card is too high, so that the temperature is reduced, and the experience of a user is not very good. In addition, the Dx control display card upper limit value only supports 5 steps, the adjusting range is relatively fixed, and the performance parameters of the display card cannot be adjusted according to specific scenes, so that better performance cannot be provided for users in part of scenes. For example, in a scenario where there is a large need for CPU performance (e.g., programming), adjusting the graphics card performance by Dx according to the graphics card temperature may result in a reduced graphics card performance requirement, but still occupies a large power consumption index, which may result in devices such as notebooks not providing sufficient CPU performance.
In addition, the general performance regulation and control method at present also directly sets the values of TPP & TGP & TDP in BIOS according to the conditions of heat dissipation, performance and the like when the equipment is designed, and the display card automatically regulates the performance according to the set values of TPP/TGP/TDP in the working process or drives the display card to automatically regulate the performance when the game/GPU single-baking/double-baking and the like require the GPU to have large performance, but the TPP/TGP/TDP parameters are not changed in the process, in other words, the performance parameters of the CPU and the display card are not changed according to the scene, and only the performance of the CPU and the display card is changed according to the power consumption of the chip, so the method cannot adapt to the different performance requirements of different scenes on the CPU and the display card.
In addition, at present, there is a method for controlling the performance of the display card by setting the TPP and the TGP of the display card through the WMI interface, and the method also has the advantages that the TPP, the TGP and the DB values are directly set, the dynamic adjustment can not be carried out according to the current user scene of the electronic equipment, the application range is smaller, the performance control accuracy of the display card can be influenced by the actual power of the CPU, and the method is unstable.
Based on the above reasons, the embodiment of the application provides a performance regulation and control method, by identifying the current scene of the device, setting specific parameters or Dx values of TPP, TGP and/or TDP according to the specific scene when performance regulation and control is required, so that the display card can perform performance regulation and control according to the current TPP, TGP and/or TDP parameters or Dx values, thereby providing more reasonable CPU and GPU performance according to the scene, better meeting the performance requirements of users in various scenes, and relatively improving the endurance of the device, thereby improving the user experience. The performance control method provided by the embodiment of the application is described in detail below.

The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application exemplifies a Windows system of a layered architecture, and illustrates a software structure of the electronic device 100.
Fig. 3 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application.
The layered architecture of the electronic device 100 divides the software into several layers, each with a distinct role and division of labor. The layers communicate with each other through a software interface.
In some embodiments, windows systems are classified into a user mode and a kernel mode. The user mode comprises an application layer and a subsystem dynamic link library. The kernel mode is divided into a firmware layer, a hardware abstraction layer (hardwareabstraction layer, HAL), a kernel and a driving layer and an executing body from bottom to top.
As shown in FIG. 3, the application layer includes applications such as music, video, games, office, performance regulating software, and the like. The application layer also includes environment subsystems, scheduling engines, system support processes, service processes, and the like. Wherein only a part of application programs are shown in the figure, the application layer can also comprise other application programs, such as shopping application, browser and the like, and the application is not limited.
The environment subsystem may expose certain subsets of the basic executive services to the application in a particular modality, providing an execution environment for the application.
The scenario recognition engine may recognize a user scenario in which the electronic device 100 is located and determine a base scheduling policy (also referred to as a second scheduling policy) that matches the user scenario.
The scheduling engine may obtain the load condition of the electronic device 100, and determine an actual scheduling policy according to the actual operation condition of the electronic device 100 by combining the load condition of the electronic device 100 and the basic scheduling policy.
The performance adjustment application may perform performance adjustment on the CPU, GPU, etc. according to the user scenario in which the electronic device 100 is located. The performance tuning application may be a stand-alone application, a software module that may be integrated with other applications (e.g., a computer housekeeping), or may be integrated in a service or engine of an operating system.
The subsystem dynamic link library comprises an API module comprising Windows API, windows native API, NVAPI, etc. The Windows APIs, which can provide system call entry and internal function support for the application program, are different in that they are Windows system native APIs. For example, windows APIs may include user. Dll, kernel. Dll, and Windows native APIs may include ntdll, dll. The user. Dll is a Windows user interface, and can be used for performing operations such as creating a window, sending a message, and the like. kernel. Dll provides an interface for applications to access the kernel. ntdll.dll is an important windows nt kernel level file that describes the interface of windows local NTAPI. When Windows is started, ntdl1.Dll resides in a particular write-protected region of memory, making it impossible for other programs to occupy this memory region.
The executives include a process manager, a virtual memory manager, a secure reference monitor, an I/O manager, windows management specifications (Windows management instrumentation, WMI), a power manager, a system event driver (SYSTEM EVENT DRIVER, osEventDriver) node, a system and chip driver (operatingsystem to System on Chip, OS2 SOC) node, and the like.
The process manager is used to create and suspend processes and threads.
The virtual memory manager implements "virtual memory". The virtual memory manager also provides basic support for the cache manager.
The security reference monitor may execute a security policy on the local computer that protects operating system resources, performs protection and monitoring of runtime objects.
The I/O manager performs device independent input/output and further processes call the appropriate device drivers.
The power manager may manage power state changes for all devices that support power state changes.
The system event driven node may interact with the kernel and the driver layer, for example, with a graphics card driver, and after determining that a GPU video decoding event exists, report the GPU video decoding event to the scene recognition engine.
The system and chip driver nodes may be used by the scheduler engine to send adjustment information to the hardware device, such as information to adjust PLl and PL2 to the CPU.
The kernel and driver layer includes a kernel and a device driver.
The kernel is an abstraction of the processor architecture, separates the difference between the executable and the processor architecture, and ensures the portability of the system. The kernel may perform thread scheduling and scheduling, trap handling and exception scheduling, interrupt handling and scheduling, etc.
The device driver operates in kernel mode as an interface between the I/O system and the associated hardware. The device drivers may include graphics card drivers, intel DTT drivers, mouse drivers, audio video drivers, camera drivers, keyboard drivers, and the like. For example, the graphics driver may drive the GPU to run and the Intel DTT driver may drive the CPU to run.
The HAL is a core state module, which can hide various details related to hardware, such as an I/O interface, an interrupt controller, a multiprocessor communication mechanism and the like, provide uniform service interfaces for different hardware platforms running Windows, and realize portability on various hardware platforms. It should be noted that, in order to maintain portability of Windows, the Windows internal components and the device driver written by the user do not directly access the hardware, but rather by calling the routine in the HAL.
The firmware layer may include a basic input output system (basic input output system, BIOS, which is a set of programs that are embedded in a Read Only Memory (ROM) chip on the motherboard of the computer, which holds the most important basic input output programs, post-boot self-test programs, and system self-start programs of the computer, which can read and write specific information of the system settings from the complementary metal oxide semiconductor (complementary metal oxide semiconductor, CMOS). Its main function is to provide the lowest, most direct hardware setup and control for the computer.
The Intel DTT driver may send instructions to the CPU via the BIOS.
It should be noted that, the embodiment of the present application is only illustrated by a Windows system, and in other operating systems (such as an android system, an IOS system, etc.), the scheme of the present application can be implemented as long as the functions implemented by the respective functional modules are similar to those implemented by the embodiment of the present application.
It will be appreciated that the layers and components contained in the layers in the software structure shown in fig. 3 do not constitute a specific limitation on the electronic device 100. In other embodiments of the application, electronic device 100 may include more or fewer layers than shown and may include more or fewer components per layer, as the application is not limited.
Fig. 4 shows a schematic of the workflow of software and hardware when the electronic device 100 schedules resources.
As shown in fig. 4, the application layer scene recognition engine includes a system probe module, a scene recognition module, and a base policy matching manager. The scene recognition module can interact with the system probe module and the basic policy matching manager respectively. The scene recognition module may send a request to the system probe module to obtain the probe status. The system probe module may acquire the operating state of the electronic device 100. For example, the system probe modules may include a power state probe, a peripheral state probe, a process load probe, an audio video state probe, a system load probe, a system event probe, and the like.
The power state probe may subscribe to a kernel state for a power state event, determine a power state according to a callback function fed back by the kernel state, where the power state includes a battery (remaining) power, a power mode, and the like, and the power mode may include an alternating current (ALTERNATING CURRENT, AC) power and a Direct Current (DC) power. For example, the power state probe may send a request to the OsEventDriver node of the execution body layer to subscribe to a power state event, which is forwarded by the OsEventDriver node to the power manager of the execution body layer. The power manager may feed back a callback function to the power state probe through the OsEventDriver node.
The peripheral state probe can subscribe a peripheral event to the kernel state, and the peripheral event is determined according to a callback function fed back by the kernel state. Peripheral events include mouse wheel slide events, mouse click events, keyboard input events, microphone input events, camera input events, and the like.
The process load probe may subscribe to the process load from kernel states and determine the load of the process (e.g., the first process) according to the callback function fed back from kernel states.
The system load probe can subscribe the system load to the kernel state, and the system load is determined according to a callback function fed back by the kernel state.
The audio and video status probe may subscribe to the kernel mode for audio and video events, and determine the audio and video events currently existing in the electronic device 100 according to the callback function fed back by the kernel mode. The audio video events may include GPU decoding events, and the like. For example, the audio video status probe may send a request to the OsEventDriver node of the executive layer to subscribe to GPU decode events, which is forwarded by the OsEventDriver node to the graphics card driver of the kernel and driver layers. The graphics card driver can monitor the state of the GPU, and after the GPU is monitored to perform decoding operation, a callback function is fed back to the audio and video state probe through the OsEventDriver node.
The system event probe can subscribe to the kernel state for system events, and the system events are determined according to a callback function fed back by the kernel state. The system events may include window change events, process creation events, thread creation events, and the like. For example, the system event probe may send a request to the OsEventDriver node of the executive layer to subscribe to a process creation event, which is forwarded by the OsEventDriver node to the process manager. The process manager may feed back callback functions to the system event probes through the OsEventDriver node after the process is created. For another example, the system event probe may also send a subscribe to focus window change event to the API module, which may monitor whether the focus window of the electronic device 100 has changed, and when it is monitored that the focus window has changed, feed back a callback function to the system event probe.
It can be seen that the system probe module subscribes to various events of the electronic device 100 from the kernel mode, and then determines the running state of the electronic device 100 according to the callback function fed back from the kernel mode, so as to obtain the probe state. After the system probe module obtains the probe state, the probe state can be fed back to the scene recognition module. After the scene recognition module receives the probe state, the scene recognition module can determine the user scene where the electronic device 100 is located according to the probe state. The user scene may include a video scene, a game scene, an office scene, a social scene, and the like. The user context may reflect the current use needs of the user. For example, when the scene recognition engine recognizes the focus window as a window of the video application, it determines that the electronic device 100 is in a video scene, which indicates that the user needs to view and browse the video using the video application. For another example, the scene recognition engine recognizes that the electronic device 100 is in a social scene when the focus window is recognized as a chat window of WeChat TM. The scene recognition module may also send the user scene to the base policy matching manager. The base policy matching manager may determine a base scheduling policy (which may also be referred to as a second scheduling policy, see for details the description in S301, S302 below) from the user scenario. The base policy matching manager may feed back the base scheduling policy to the scene recognition module. The scene recognition module may send the base scheduling policy and the user scene to a scheduling engine of the application layer.
As shown in fig. 4, the scheduling engine includes a load manager, a chip policy aggregator, and a scheduling executor. The load management controller can receive the basic scheduling strategy and the user scene sent by the scene identification module. The load manager may also obtain the system load from the system probe module, and adjust the basic scheduling policy according to the system load and the user scenario, to obtain an actual scheduling policy (which may also be referred to as a first scheduling policy, see the description in S310 below for details). The actual scheduling policy includes an OS scheduling policy and a first CPU power consumption scheduling policy (which may also be referred to as a first sub-policy). The load manager may send the OS scheduling policy to the scheduling executor, and the scheduling executor may schedule based on the OS scheduling policy. The OS scheduling policy is used to adjust the process priority and I/O priority of the focal process. For example, the schedule executor may send an instruction to the process manager to adjust the process priority of the focal process, in response to which the process manager adjusts the process priority of the focal process. For another example, the scheduling executor may send an instruction to the I/O manager to adjust the I/O priority of the focal process, in response to which the I/O manager adjusts the I/O priority of the focal process.
The load manager may also send a first CPU power consumption scheduling policy to the chip policy aggregator, which may obtain a second CPU power consumption scheduling policy (also referred to as a second sub-policy, see the description in S317-S325 below) based on the chip platform type of the CPU and the first CPU power consumption scheduling policy. The chip platform types of the CPU are mainly divided into two types, namely Chaowei semiconductor company(Advanced micro devices, AMD) CPU and Intel/>These two types of CPUs are different in the adjustment manner of CPU power consumption, and therefore need to be distinguished.
If the type of the chip platform of the CPU is AMD (also referred to as a first type), the scheduling executor may send an instruction to adjust EPP to the power manager to adjust EPP of the CPU. In addition, the schedule executor may also send instructions to the OS2SOC driving node to adjust PL1, PL2 to adjust PL1 and PL2 of the CPU.
If the type of the chip platform of the CPU is IntelThe scheduling executor may send the second CPU power consumption scheduling policy to the Intel DTT driver through the WMI plug-in, where the second CPU power consumption scheduling policy may include a minimum value of PL1, a maximum value of PL1, durations of PL2 and PL2, and EPP, and the CPU is operated by the Intel DTT driver based on the second CPU power consumption scheduling policy.
The performance regulation and control method provided by the embodiment of the application is mainly divided into two processes, namely: (1) determining a user scene in which the electronic device is located; (2) And determining the performance parameters of the electronic equipment according to the user scene where the electronic equipment is located. The above two processes will be respectively described below with reference to the drawings.
The following will take an example that the electronic device is in a video playing scene, and refer to fig. 5, to describe an interaction process of a part of modules in the electronic device shown in fig. 4. As shown in fig. 5, a flow of determining a user scenario where an electronic device is located in the performance adjusting method provided by the embodiment of the present application is as follows:
s501, the system probe module sends a request for subscribing to a process creation event to the OsEventDriver node.
As shown in fig. 5, the scene recognition engine includes a system probe module that includes a system event probe. In an embodiment of the present application, a request to subscribe to a process creation event may be sent by a system event probe to a OsEventDriver node located at the executable layer. Wherein the request to subscribe to a process creation event may also be referred to as a first request.
In an alternative embodiment, the request to subscribe to a process creation event may carry a process name. That is, the scene recognition engine may subscribe to only the creation events of the specified process, reducing interference of the creation events of irrelevant processes. For example, the specified process may be a process of a video application, a process of a game application, a process of an office application, a process of a social application, and so on. Of course, in other embodiments, the scenario recognition engine may not limit the subscribed process creation events.
The OsEventDriver node sends a request to the process manager to subscribe to a process creation event.
The request of the process creation event may refer to the description of S501, which is not described herein.
That is, the system event probe of the scene recognition engine may send a request to the process manager through the OsEventDriver node to subscribe to the process creation event.
It will be appreciated that the OsEventDriver node will register a callback with the process manager, the role of which is to return the process creation event to the OsEventDriver node after the process manager creates the process.
S503, the system probe module sends a request for subscribing the GPU decoding event to the OsEventDriver node.
As also shown in fig. 4, the system probe module further includes an audio-visual status probe. In the embodiment of the application, the audio and video status probe of the system probe module can send a request for subscribing the GPU decoding event to the OsEventDriver node. Wherein, the request to subscribe to the GPU decode event may also be referred to as a third request.
And S504, the OsEventDriver node sends a request for subscribing the GPU decoding event to the display card driver.
That is, the audio video status probe of the scene recognition engine may send a request to the graphics card driver through the OsEventDriver node to subscribe to GPU decode events. Similarly, the OsEventDriver node may register a callback with the graphics card driver, where the role of registering the callback is to return the GPU decoding event to the OsEventDriver node when the graphics card driver monitors that the GPU performs the decoding operation.
S505, the system probe module sends a request for subscribing to a focus window change event to the API module.
The API module may include a windows user interface implemented by user32.dll, which may be used to create a window. In an alternative embodiment, a request to subscribe to a focus window change event may be sent by a system event probe of the system probe module to a windows user interface of the API module. Wherein the request to subscribe to the focus window change event may also be referred to as a second request.
Likewise, the system event probe may register a callback with the API module, where the role of registering the callback is to return the focus window change event to the system event probe when the (windows user interface of the) API module monitors that the focus window has changed.
The focus window is a window with focus, and the high probability is a window which is needed to be used by a user currently. Thus, by monitoring the focus window, the user's need for use can be determined. For example, the focus window is a window of the video application, which indicates that the user needs to browse and play the video. As another example, the focus window is a window of a gaming application, indicating that the user desires to play a game. By monitoring whether the focus window changes, it can be determined whether the user's needs have changed. For example, the focus window changes from the window of the video application to the window of the game application, indicating that the user's current needs change from watching video to playing a game.
The above-mentioned steps S501, S503 and S505 are not strictly sequential, and may be sequentially performed in the order shown in fig. 5, or may be simultaneously performed, or may be sequentially performed in the order of S503, S501 and S505, sequentially performed in the order of S503, S505 and S501, sequentially performed in the order of S505, S501 and S503, or sequentially performed in the order of S505, S503 and S501. Accordingly, there is no strict order among S502, S504, and S506, as long as it is satisfied that S502 is performed after S501, S504 is performed after S503, and S506 is performed after S505, and no specific limitation is made herein.
S506, responding to the received operation of starting the video application by the user, and sending a process creation request to a process manager by the video application.
Wherein the creation process request includes a storage address of the video application.
The video application may send a request to create a process to a process manager (not shown) through the kernel32.Dll interface and the ntdll interface of the API module.
S507, the process manager creates a video application process.
Specifically, the process manager may query the binary file of the video application through the storage address. By loading the binary file of the video application program, a process running environment can be created, and the video application process is started.
Wherein the Windows operating system defines a run of an application as a process. A process may own multiple threads. A window is an example of a window structure, a graphical user interface (GRAPHICAL USER INTERFACE, GUI) resource, a window is created by a thread, and a thread can own all the windows it creates. In the embodiment of the application, when the electronic device runs the video application, the process manager needs to create a process of the video application, namely, a video application process (namely, a first process). The video application process comprises a plurality of threads, the plurality of threads comprise a thread 1, the thread 1 can be used for creating a main window of the video application, and the main window is a window integrated with all function keys of the video application.
S508, the process manager reports the process creation event to the OsEventDriver node.
Wherein the process creation event may include a name of the process created by the process manager. In the embodiment of the application, the name of the process is the name of the video application process. Of course, if the process manager creates a process of another application, the name of the process corresponds to the name of the process of the other application.
As already described above, the OsEventDriver node sent a request to the process manager to subscribe to the process creation event and registered the callback. Thus, the process manager may report a process creation event to the OsEventDriver node after creating the video application process.
And S509, osEventDriver nodes report the process creation event to the system probe module.
The description of the process creation event is S508, and is not described herein.
In the embodiment of the present application, the OsEventDriver node may report the process creation event to a system event probe of the system probe module.
S510, the system probe module sends a process creation event to the scene recognition module.
S511, in response to the call request of the thread 1, the API module creates the window 1.
After the process manager creates the video application process, the thread 1 of the video application process actively calls the windows user interface creation window 1 of the API module. For example, as shown in fig. 6 (a), the electronic device may display a window 601, where the window 601 may be a desktop, and may also be referred to as a main interface. The window 601 includes an icon 602 of a video application. The electronic device may receive an operation in which the user clicks on the icon 602 of the video application, and in response to the operation, as shown in (b) of fig. 6, the electronic device displays a window 603 (i.e., window 1, which may also be referred to as a first window). In the above procedure, the focus window is changed from the original window 601 to the window 603.
S512, the API module reports the focus window event to the system probe module.
In the embodiment of the present application, after creating window 1, the windows user interface of the API module may obtain the name of the first process (i.e. the focus process) and the name of the second process, where the first process is the process corresponding to the current focus window (i.e. window 1), and the second process is the process corresponding to the last focus window (e.g. window 2). Illustratively, the process corresponding to the window 1 is a video application process (first process), the name of which is, for example, hlive. Exe, and the process corresponding to the window 2 is a process (second process) of a windows program manager, the name of which is, for example, explorer. Exe. And because the name of the first process is inconsistent with the name of the second process, the API module determines that the focus window changes, and reports a focus window event to a system event probe of the system probe module. Wherein the focus window change event includes the name of the first process (i.e., the focus process). Illustratively, the first process is a video application process, and the focus window change event carries a name of the video application process.
Note that, in the case where the electronic device has already started the video application, the electronic device may not execute S506 to S511. After the system probe module sends a request for subscribing the focus window change event to the API module, if the user switches the focus window to the window of the video application, the API module can also detect that the focus window changes and report the focus window event to the system probe module.
S513, the system probe module sends a focus window event to the scene recognition module.
S514, the scene recognition module determines that the type to which the first process belongs is a video type.
The electronic device may be preconfigured with an application list, and the scene recognition module may query whether the application list includes the first process. If the application list includes the first process, the scene recognition module may determine a type to which the first process belongs. The application list comprises the process name of each application and the type of the application. By way of example, the application list may be as shown in Table 1:
TABLE 1
| Application of | Process name | Type(s) |
| Glory video | hlive.exe | Video class |
| word | word.exe | Office class |
| Shooting game | shot.exe | Game class |
| WeChat TM | wechat.exe | Social class |
| …… | …… | …… |
For example, the name of the first process is hlive. Exe, the scene recognition module may determine that the type to which the first process belongs is a video class. For another example, the name of the first process is wechat. Exe, the scene recognition module may determine that the type to which the first process belongs is a social class. It should be noted that, table 1 is only used as an example, and in fact, table 1 may further include process names of more applications and types to which the process names belong.
It should be noted that the purpose of this step is to primarily determine the user scenario in which the electronic device is located. The user scene in which the electronic device is located may include a video scene, a game scene, a social scene, an office scene, a browser scene, and so forth. The video scene further comprises a video playing scene and a video browsing scene. The social scenes may further include text chat scenes, voice chat scenes, video chat scenes, and so on. The office scenes further may include document editing scenes, document browsing scenes, video conferencing scenes, and the like. The browser scene may include a browse web scene, a play video scene, and the like.
In this step, the type of the user scene where the electronic device is located may be determined by the type to which the first process belongs. For example, if the type to which the first process belongs is determined to be a video class, it may be determined that the electronic device is in a video scene; for another example, if it is determined that the type to which the first process belongs is a game class, it may be determined that the electronic device is in a game scene.

Through step S535, the scene recognition engine may determine a specific operation performed by the first process through the GPU, and further determine a specific operation of the user using the video application. For example, if the GPU engine of the first process is GPU video processing, it indicates that the first process is using the GPU to perform decoding operation, and the user can be considered to play video using the video application. For another example, if the GPU engine of the first process is not GPU video processing, it indicates that the first process is not using the GPU to perform decoding operations, then the user has a high probability of browsing video resources on the video application, and not yet playing video.

The process information of the first process comprises information such as the name of the first process, the application type to which the first process belongs, the GPU occupancy rate of the first process, and a GPU engine used by the first process.
In summary, if the type of the first process (focus process) is a video type, the GPU occupancy rate of the first process is greater than 0, and the GPU engine of the first process is GPU video processing, it can be determined that the electronic device is in a video playing scene.

The above description describes how to identify a user scene where an electronic device is located, after determining the user scene where the electronic device is located, the electronic device may further determine whether performance adjustment is required according to the user scene where the electronic device is located, and when performance adjustment is required, specific parameter values or Dx values of TPP, TGP and/or TDP are set according to the user scene where the electronic device is located, so that a graphics card performs performance adjustment according to current TPP, TGP and/or TDP parameters or Dx values, thereby providing more reasonable CPU and GPU performance according to the scene, not only better meeting performance requirements of users in various scenes, but also relatively improving endurance of the device, and thus improving user experience.
Fig. 8 is a flowchart of a performance adjustment method according to an embodiment of the present application.
As shown in fig. 8, the performance adjustment method provided by the embodiment of the present application specifically includes:
in step S801, the scene recognition engine determines a user scene of the electronic device, and sends scene information to the performance adjustment application.
The scene information is used for indicating a user scene where the electronic equipment is located. For example, the electronic device may pre-assign unique identifiers to different user scenarios, and the scenario information may include the unique identifiers of the user scenarios. For example, the identification (e.g., V01) may indicate that the electronic device is in a video playback scene. For another example, the identification (e.g., V02) may indicate that the electronic device is in a video browsing scenario.
Regarding the process of determining the user scene where the electronic device is located by the scene recognition module, refer to S501 to S536 specifically, and are not described herein again.
In step S802, the performance adjustment application determines parameter values of performance parameters according to the scene information.
Wherein the performance parameters include a first performance parameter and a second performance parameter. The first performance parameter includes at least one of a TDP power consumption of the CPU, a TGP power consumption of the GPU, a TPP power consumption of the GPU, and a DB power consumption of the GPU. The second performance parameter includes a Dx value for the GPU.
Illustratively, in the embodiment of the present application, the performance requirements of various user scenarios may be predetermined through testing, for example, the performance required by an office scenario may be determined through testing, and the parameter value of the first performance parameter in the office scenario may be determined according to the performance, for example, specific parameter values of the TDP power consumption of the CPU, the TGP power consumption of the GPU, the TPP power consumption of the GPU, and the DB power consumption of the GPU may be determined.
Illustratively, in embodiments of the present application, the performance requirements in each scenario may be determined by building a user dynamic test model. The dynamic test model can be used for determining CPU performance, GPU performance and the like when the electronic equipment runs various types of applications, so that the performance requirements of the electronic equipment in various scenes are determined based on the data, and further, specific numerical values of first performance parameters in various scenes are determined based on the performance requirements.
By adopting different first performance parameters in various scenes, the electronic equipment can ensure the smooth operation of the current application and simultaneously reduce the power consumption of the equipment. For example, when the electronic device is in an office scenario, for example, because the performance requirement is low, the low TGP, TDP, TPP and DB values can be set, so that the power consumption of the device is reduced and the cruising time of the device is prolonged while the smooth running of the office application is ensured. When the electronic equipment is in a game scene, a performance test scene and a 3D rendering scene, the GPU performance requirement is larger, and then TPP, DB, TGP values can be larger, so that higher performance can be provided for the GPU, and the game running requirement is met. When the electronic equipment is in a programming scene, the CPU performance requirement is larger, the GPU performance requirement is smaller, the TPP is larger, the TGP and DB values are smaller, thereby meeting the programming requirement and reducing the equipment power consumption. In other words, in the embodiment of the application, the parameter value of the first performance parameter is dynamically adjusted according to the scene where the electronic equipment is located, so that the smooth operation of the application is ensured, the power consumption of the equipment is reduced, and the endurance of the equipment is prolonged. Compared with the existing regulation and control mode of setting TDP, TGP or TPP values when the electronic equipment leaves the factory, the method can better meet the performance requirements of the application, reasonably distributes CPU power consumption and GPU power consumption according to specific application, and improves user experience.
It should be appreciated that for electronic devices, the TPP is generally designed to have an upper limit based on processor performance and heat dissipation, and in embodiments of the present application the specific value set TPP, TDP, TGP according to the electronic device is set within the upper limit of the TPP. For example, the maximum TPP of the electronic device is 90W, the TPP may be set to 30W in a scenario where the performance requirement is low. In a scenario where performance needs to be large, the TPP may be set to a large value of 60W, 70W, or even 90W. And when the CPU performance requirement is larger, the TDP is larger, and when the GPU performance requirement is larger, the TGP is larger. Compared with the current performance regulation mode based on TGP, TDP, TPP, the CPU and GPU power consumption can be allocated more flexibly. The method is characterized in that the current regulation and control mode is adopted, TPP is generally set to be 60W, TDP is set to be 25W, TGP is set to be 35W, performance is automatically regulated by a processor based on TPP, TGP, TDP according to requirements, and the mode cannot reasonably distribute CPU and GPU power consumption according to requirements due to the fact that TDP and TGP are set. By adopting the mode of the embodiment, the TGP can be set to 40W and the TDP can be set to 20W in the scene of larger GPU performance requirement and smaller CPU performance requirement, so that the performance requirement of the application can be better met.
It should also be understood that a typical electronic device is configured with an equalization mode and a performance mode in which the performance parameter upper limit is different, and when the electronic device is in the performance mode, the parameter value of the first performance parameter in each user scenario is set within the upper limit of the first performance parameter in the performance mode. When the electronic equipment is in the balanced mode, parameter values of the first performance parameters in each user scene are set in the upper limit value of the first performance parameters in the balanced mode. For example, if the TGP upper limit is 50W in the performance mode and the TGP upper limit is 30W in the equalization mode, the TGP value of each user scene is set within the upper limit of 50W in the performance mode and the TGP value of each user scene is set within the upper limit of 30W in the equalization mode.
Further, in an embodiment of the present application, the performance requirements of various user scenarios may be predetermined by testing, for example, determining the performance required for an office scenario by testing, and determining the parameter value of the second performance parameter in the office scenario according to the performance. The performance of the GPU can be adjusted more finely by adjusting the first performance parameter, and more reasonable performance is provided for the GPU. GPU performance may be adjusted more or more quickly by adjusting the second performance parameter to rapidly reduce (or increase) GPU performance.
It should be noted that in the embodiment of the present application, the first performance parameter or the second performance parameter may be adjusted according to the needs of the user scenario.
In an alternative embodiment, the default Dx is set to D1 (maximum GPU power consumption) and GPU performance is adjusted by adjusting the first performance parameter when a user scene changes.
In an alternative embodiment, when the GPU performance required by the user scene is small, the Dx value may be adjusted to D4 or D5 to directly limit the GPU performance to a smaller value, thereby extending the device endurance.
In an alternative embodiment, the device is enabled to provide greater GPU and CPU performance by adjusting the first performance parameter as the performance requirements of the current user scene increase relative to the performance requirements of the previous user scene.
In an alternative embodiment, when the remaining battery power of the electronic device is insufficient, for example, less than a set percentage (for example, less than 20%), the Dx value is adjusted to D4 or D5, so as to directly limit the GPU performance to a smaller value, thereby prolonging the device endurance.
In an alternative embodiment, when the temperature of the electronic device is too high, for example, greater than a set threshold (e.g., greater than 90 ℃), the Dx value is adjusted to D4 or D5 to directly limit the GPU performance to a smaller value, thereby extending the device endurance.
It should be noted that the temperature of the electronic device includes a CPU temperature, a GPU temperature, a motherboard temperature, and the like, and that the temperature of the electronic device is too high refers to that one or more of the CPU temperature, the GPU temperature, the motherboard temperature, and the like is too high.
In step S803, the performance adjustment application sends the parameter value of the performance parameter to the BIOS through the WMI interface.
After determining the parameter value of the performance parameter in the aforementioned step S802, the performance control application invokes the WMI interface to send the parameter value of the performance parameter to the BIOS.
In step S804, the BIOS writes the parameter value of the performance parameter into the location indicated by the ACPI, and notifies the GPU driver to read the parameter value of the performance parameter.
Illustratively, a storage location in the internal memory (i.e., the memory) is specified in the ACPI, where the first performance parameter and the second performance parameter are stored, and after the BIOS obtains the parameter values of the first performance parameter and the second performance parameter, the BIOS modifies the performance parameter of the storage location to the latest value, and then notifies the GPU driver to read the latest performance parameter of the graphics processor.
The storage location of the first performance parameter and the storage location of the second performance parameter may be the same or different.
In step S805, the GPU driver reads the parameter value of the performance parameter, and adjusts and controls the performance of the GPU according to the parameter value of the performance parameter.
Specifically, the BIOS generates an SCI interrupt after modifying the value of the performance parameter of the graphics processor, and the graphics driver invokes a graphics control method (ACPI) to read the current value of the performance parameter of the graphics processor after receiving the SCI interrupt (i.e., event notification).
And after the performance parameters are read, regulating and controlling the performance of the graphics processor according to the performance parameters. For example, after the current value of Dx is read, the performance of the display card is controlled according to the power consumption corresponding to the current value of Dx. For example, when the current Dx value is D3 and the power consumption of the corresponding graphics card is 15W, the GPU driver controls the graphics card to limit the maximum power consumption to 15W. For another example, after reading the current value of TGP, TDP, TPP, DB, the graphics card performance is controlled according to the current value of TGP, TDP, TPP, DB.
It should be noted that, when the graphics card performance is controlled according to the current value of TGP, TDP, TPP, DB, the GPU driver also communicates with the CPU driver to obtain the current CPU power consumption, and adjusts the graphics card performance according to the current TGP, TDP, TPP, DB value.
Illustratively, for example, with a current TGP of 40W, a TDP of 30W, a TPP of 70W, and a DB of 15W, the GPU driver may limit the GPU power consumption to between 25W (40-15) and 55W (40+15) with more CPU real power consumption. That is, when the actual power consumption of the CPU is small, for example, the actual power consumption of the CPU is 15W, the GPU power consumption can be adjusted within 55W, that is, the maximum GPU power consumption of 55W can be provided. For example, when the actual power consumption of the CPU is 30W, the GPU power consumption can be adjusted within 25W, that is, the maximum GPU power consumption of 25W can be provided, so that sufficient CPU performance can be ensured to be provided.
The following describes a performance adjustment method according to an embodiment of the present application with reference to fig. 9 and 10.
FIG. 9 is an exemplary tuning process of a performance tuning method provided by an embodiment of the application.
As shown in fig. 9, an exemplary regulation process of the performance regulation method provided by the embodiment of the present application includes:
In step S901, in response to the operation for starting the first application, the first performance parameter of the electronic device is a first parameter value before the first application is started.
Illustratively, the first application is, for example, a programming application, such as various programming applications.
The first performance parameter includes at least one of TDP power consumption of the CPU, TGP power consumption of the GPU, TPP power consumption of the GPU, DB power consumption of the GPU.
The first parameter value may be a set of parameters including a specific value of TDP, TPP, TGP, DB. The first parameter value is, for example, TDP30W, TPP, 70, W, TGP, 40W, DB15W. By reducing TGP and DB, the GPU performance can be made efficient, allowing the device to provide adequate CPU performance.
In step S902, the scene recognition engine determines that the electronic device is in a first user scene according to the first application.
Illustratively, the first user scenario is a programming scenario. Regarding the process of determining the user scene where the electronic device is located by the scene recognition module, refer to S501 to S536 specifically, and are not described herein again.
In step S903, the scene recognition engine determines to send the first scene information to the performance tuning application.
For example, the electronic device may pre-assign unique identifiers to different user scenarios, and the scenario information may include the unique identifiers of the user scenarios.
In step S904, at a first time point, the performance adjustment application adjusts the first performance parameter to a second parameter value according to the first scenario information, the second parameter value being different from the first parameter value.
The second parameter value may be a set of parameters including the specific value of TDP, TPP, TGP, DB. The second parameter value being different from the first parameter value means that there is a corresponding difference in at least one parameter from the first parameter value and the second parameter value. For example, the TGP value in the first parameter value and the TGP value in the second parameter value are different.
The second parameter value is, for example, TDP30W, TPP60W, TGP W, DB5W.
By reducing TGP and DB, the GPU performance can be made efficient, allowing the device to provide adequate CPU performance.
In step S905, the performance adjustment application sends the second parameter value to the BIOS through the WMI interface.
In step S906, the BIOS writes the second parameter value to the location of the ACPI finger, and notifies the GPU driver to read the second parameter value.
Specifically, the BIOS writes the second parameter value to a storage location of the first performance parameter of the ACPI finger and notifies the GPU driver to read the second parameter value.
In step S907, the GPU driver reads the second parameter value, and adjusts the performance of the GPU according to the second parameter value.
The process of the GPU reading the second parameter value is described in S805, and will not be described in detail herein.
Step S908, a second application is launched in response to the operation for operation.
Illustratively, the second application is a gaming application, such as a 3A large game.
In step S909, the scene recognition engine determines that the electronic device is in a second user scene according to the second application.
Illustratively, the second user scenario is a game scenario. Regarding the process of determining the user scene where the electronic device is located by the scene recognition module, refer to S501 to S536 specifically, and are not described herein again.
In step S910, the scene recognition engine determines to send the second scene information to the performance tuning application.
