Detailed Description

For ease of understanding, a description of some of the concepts related to the embodiments of the present application are given by way of example for reference.

It should be noted that "at least one" in this application means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and the representation may have three relationships, for example, a and/or B may represent: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The terms "first," "second," "third," "fourth" and the like in the description and in the claims and drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

In order to better understand the cold start method and the related device provided in the embodiments of the present application, an application scenario of the cold start method of the present application is described below.

As shown in fig. 1, the cold start method provided in the embodiment of the present application is applied to an electronic device 10. The electronic device 10 includes a plurality of functions, such as a photographing function, a picture viewing function, and the like. The electronic device 10 may be an embedded device such as a smart door lock, a smart doorbell, a drone, a handgun, or the like. Fig. 1 illustrates an electronic device 10 as a portable camera.

The process of powering up the electronic device 10 to be able to function properly is referred to as a cold start. According to the cold start method provided by the embodiment of the application, the electronic device 10 can enter different start scenes during cold start, and the different start scenes correspond to different functions. The electronic device 10 preferentially starts different functions in different starting scenes, so that a user can quickly use the required functions, the response speed of the electronic device after cold start is improved, and the starting experience of the user is improved. For example, the electronic device 10 is a personal photo, which has a photographing function and a picture viewing function. The start scene of the carry-on shooting comprises a shooting scene and a view scene. The snapshot scene corresponds to a photographing function and is used for photographing pictures or videos through a camera which takes the pictures with the body, and the view scene corresponds to a picture viewing function and is used for viewing the pictures or videos which are stored with the body through a display screen which takes the pictures with the body. If the user needs to take a picture quickly after cold start, the user selects to enter a snapshot scene, and the portable shooting starts a shooting function firstly and then starts a picture viewing function of the portable shooting when cold start. The portable photo can take a picture after the photographing function is started, and the picture checking function is not required to be started. If a user needs to quickly view pictures or videos after cold start, selecting to enter a view scene, starting a picture viewing function of the portable shooting at first and then starting a shooting function of the portable shooting at the time of cold start. The portable photo can view the picture or video stored by the portable photo after the picture viewing is started, and the photographing function is not required to be started.

Each start-up scenario of the electronic device 10 may correspond to one function or may correspond to multiple functions. If one starting scene of the electronic device corresponds to a plurality of functions, the functions can be started preferentially according to a preset sequence, or the functions can be started preferentially according to a random sequence.

In another embodiment of the present application, the cold start method may be applied to a smart door lock. The starting scene of the intelligent door lock comprises an out-door face recognition unlocking (camera shooting recognition) scene and an in-door cat eye preview (screen display camera shooting image) scene. If a user needs to unlock quickly after cold start, the user selects to enter an out-door face recognition unlocking scene, the intelligent door lock starts the function corresponding to the out-door face recognition unlocking scene, and then starts the function corresponding to the in-door cat eye preview. If a user needs to quickly preview the peephole after cold start, selecting to enter a peephole preview scene in the door, starting the function corresponding to the peephole preview in the door by the intelligent door lock, and starting the function corresponding to the face identification unlocking scene outside the door.

The driver provides an interface for hardware (e.g., a display screen) to an operating system for controlling the hardware operation. The correspondence between the driver and the start scene represents the driver needed to implement the function corresponding to the start scene. Taking the take-shot as shown in fig. 1 as an example, for a shooting scene, the corresponding drivers include General-purpose input/output (GPIO) drivers, inter-Integrated Circuit (I2C) drivers, and image sensor drivers. For the view scene, the corresponding drivers include a display screen driver, a memory card (e.g., secure Digital card) driver.

Referring to fig. 2, the electronic device includes a scene a (i.e., a start scene a), a scene B (i.e., a start scene B), and a scene C (i.e., a start scene C), where the driver 1 corresponds to the scene a, the driver 2 corresponds to the scene a, the driver 3 corresponds to the scene a, the scene B (i.e., the start scene B), the driver 4 corresponds to the scene B, the driver 5 corresponds to the scene B, the scene C, the driver 6 corresponds to the scene C, and the driver 7 corresponds to the scene C. That is, scene a corresponds to driver 1, driver 2, and driver 3, scene B corresponds to driver 3, driver 4, and driver 5, and scene C corresponds to driver 5, driver 6, and driver 7.

In one embodiment of the present application, the electronic device includes a plurality of start scenes, and when the electronic device needs to enter one target start scene during cold start, the electronic device preferentially starts a function corresponding to the target start scene during cold start, and then starts functions corresponding to other start scenes. The electronic device may start functions corresponding to other partial start scenes, or may start functions corresponding to all other start scenes.

In another embodiment of the present application, the electronic device includes a plurality of start scenes, and when the electronic device needs to enter one target start scene during cold start, the function corresponding to the target start scene is started during cold start of the electronic device, and the functions corresponding to other start scenes are not started.

If the electronic device starts the functions corresponding to other start scenes (may be other part of start scenes or all of start scenes) in addition to the functions corresponding to the start target start scene during cold start, the start sequence corresponding to each start scene may be set. The starting sequence corresponding to one starting scene is the starting sequence corresponding to the starting scene when the starting scene is taken as the target starting scene.

In the embodiment shown in fig. 3, the starting sequence corresponding to the starting scene is represented by a starting script. In fig. 3, "caseA" indicates a function corresponding to scene a, "caseB" indicates a function corresponding to scene B, "caseC" indicates a function corresponding to scene C, "user state startup script 1" indicates a startup script corresponding to scene a, "user state startup script 2" indicates a startup script corresponding to scene B, and "user state startup script 3" indicates a startup script corresponding to scene C. As can be seen from fig. 3, the starting sequence corresponding to the scene a is to start the function corresponding to the scene a, then start the function corresponding to the scene B, and finally start the function corresponding to the scene C; the starting sequence corresponding to the scene B is to start the function corresponding to the scene B, then start the function corresponding to the scene A, and finally start the function corresponding to the scene C; the starting sequence corresponding to the scene C is to start the function corresponding to the scene C, then start the function corresponding to the scene A, and finally start the function corresponding to the scene B.

In other embodiments of the present application, the start sequence corresponding to the start scene may be represented by other manners. For example, the start-up sequence corresponding to the start-up scene may be represented by hard coding.

Taking the carry-on photo shown in fig. 1 as an example, assuming that the target starting scene is a snap shot scene, other starting scenes comprise view scenes, and the function corresponding to the view scenes is a picture viewing function, then the carry-on photo viewing function is started.

In the embodiment shown in fig. 5, in the cold start process of the electronic device, the function corresponding to the target start scene is started first, then the functions corresponding to other start scenes are started, and after the function corresponding to the target start scene is started, the user can use the function corresponding to the target start scene, so that the user can quickly use the required function, the response speed of the electronic device after cold start is improved, and the start experience of the user is improved.

In an embodiment of the present application, a startup sequence corresponding to the target startup scene may be preset. Before initializing the drivers corresponding to other starting scenes of the electronic device, a starting sequence corresponding to the target starting scene is set, and the drivers corresponding to the other starting scenes of the electronic device are initialized and the functions corresponding to the other starting scenes are started according to the starting sequence corresponding to the target starting scene. The starting sequence corresponding to the target starting scene can be set through the starting script. For example, referring to fig. 3, assume that a scene a is a target start scene, and the start sequence corresponding to the scene a is to start the function corresponding to the scene a first, then start the function corresponding to the scene B, and finally start the function corresponding to the scene C.

Fig. 6 is a flowchart of a cold start method according to another embodiment of the present application. The cold start method provided by the embodiment is applied to the electronic equipment.

601, after the electronic device is powered on and the kernel is started, determining a target starting scene of the electronic device.

If the electronic device further includes other functions (functions other than the functions corresponding to the start scene), in this step, the driver corresponding to the other functions of the electronic device is initialized.

Taking the portable photo shown in fig. 1 as an example, if the portable photo further includes an alarm clock function, a driver corresponding to the alarm clock function is initialized.

607, enabling other functions of the electronic device.

If the electronic device further comprises other functions, in this step, the other functions of the electronic device are started.

Taking the portable racket as shown in fig. 1 as an example, if the portable racket further includes an alarm clock function, the alarm clock function of the portable racket is started.

In the embodiment shown in fig. 6, during a cold start process, the electronic device starts a function corresponding to a target start scene, starts functions corresponding to other start scenes, and starts other functions of the electronic device. After the function corresponding to the starting target starting scene is started, the user can use the function corresponding to the starting target starting scene, so that the user can quickly use the required function, the response speed of the electronic equipment after cold starting is improved, and the starting experience of the user is improved.

Fig. 7 is a flowchart of a cold start method according to another embodiment of the present application. The cold start method provided by the embodiment is applied to the electronic equipment. The electronic device includes a kernel-mode process and a user-mode process. The user state process comprises a user state root process and a scene service process. The dashed lines in the figure represent inter-process communication.

The running environment of the program is divided into a user mode and a kernel mode. The application program runs at a low privilege level, and the running environment is in a user mode and cannot directly access kernel space and computer hardware. Applications may use kernel-mode functionality, such as accessing computer hardware, through kernel interfaces such as system calls. The operating system's operating environment is kernel mode.

The process running in the kernel-mode running environment is a kernel-mode process, and the process running in the user-mode running environment is a user-mode process.

As described in fig. 7, the cold start method provided in this embodiment includes:

701, after the electronic device is powered on and the kernel is started, the kernel-mode process determines a target starting scene of the electronic device.

In one embodiment of the present application, a kernel-mode process may receive a scenario selection signal, and determine a target startup scenario according to the scenario selection signal.

In another embodiment of the present application, the kernel-mode process may detect environmental information of the electronic device, and determine the target startup scenario according to the environmental information of the electronic device.

Taking the portable shot shown in fig. 1 as an example, the portable shot receives a first scene selection signal, and the kernel-mode process determines that the target starting scene is a snapshot scene according to the first scene selection signal.

702, the kernel mode process determines whether a driver corresponding to the target boot scenario has been initialized.

Taking the carry-on photo shown in fig. 1 as an example, if the target starting scene is a capture scene, and the driver corresponding to the capture scene includes a GPIO driver, an I2C driver and an image sensor driver, the kernel-mode process determines whether the carry-on GPIO driver, the I2C driver and the image sensor driver are initialized.

703, if the driver corresponding to the target start scene is not initialized, initializing the driver corresponding to the target start scene by the kernel state process.

Taking the carry-on shooting as an example in fig. 1, the target starting scene is a shooting scene, the driver corresponding to the shooting scene comprises a GPIO driver, an I2C driver and an image sensor driver, and if the carry-on shooting GPIO driver, the I2C driver and the image sensor driver are not initialized, the kernel-mode process initializes the carry-on shooting GPIO driver, the I2C driver and the image sensor driver.

The kernel mode process marks 704 that the driver corresponding to the target boot scenario has been initialized.

In this embodiment, a flag bit may be used to indicate whether the driver corresponding to the target boot scene is initialized. For example, if the flag bit is 1, it indicates that the driver corresponding to the target boot scene is initialized; if the flag bit is 0, it indicates that the driver corresponding to the target startup scene is not initialized.

After initializing the driver corresponding to the target boot scenario, the kernel-mode process may modify the flag bit to indicate that the driver corresponding to the target boot scenario is initialized. For example, when the driver corresponding to the target boot scene is not initialized, the flag bit is set to 0, and after initializing the driver corresponding to the target boot scene, the flag bit is modified to 1.

705, the kernel-mode process starts the user-mode root process.

706, the user state root process obtains the target start scene from the kernel state process.

707, the user state root process creates a scene business process for the target startup scene.

Continuing taking the carry-on shot as shown in fig. 1 as an example, assume that the target starting scene is a shot scene, and the user state root process creates a scene service process for the shot scene.

708, the scene business process starts the function corresponding to the target start scene.

Taking the portable shooting as shown in fig. 1 as an example, assuming that the target starting scene is a snapshot scene and the function corresponding to the snapshot scene is a shooting function, the scene service process starts the shooting function of the portable shooting.

709, the scene service process sends a first notification to the user state root process, where the first notification is used to inform the user state root process that the starting of the target starting scene corresponding function is completed.

The user state root process blocks 710 from waiting for the first notification.

When the first notification is received, the user state root process sends a second notification to the kernel state process, and the second notification is used for notifying the kernel state process that the function corresponding to the target starting scene is started, and the flow goes to 702.

And after the user state root process sends a second notification to the kernel state process, the electronic equipment falls into the kernel state from the user state.

712, if the driver corresponding to the target startup scenario is initialized, the kernel-mode process initializes the drivers corresponding to other startup scenarios of the electronic device.

713, the kernel-mode process sends a third notification to the user-mode root process, which informs the user-mode root process that the initialization of the driver corresponding to the other startup scenario is completed.

714, the user state process blocks waiting for a third notification.

715, after receiving the third notification, the user state root process starts the functions corresponding to other starting scenes of the electronic device.

Taking the carry-on photo shown in fig. 1 as an example, assuming that the target starting scene is a snap shot scene, other starting scenes comprise view scenes, and the function corresponding to the view scenes is a picture viewing function, then the user state root process starts the carry-on photo viewing function.

According to the technical scheme of fig. 7, the electronic device performs cold start in the electronic device including the kernel mode and the user mode, and the electronic device can enter different start scenes in the cold start process to preferentially start different functions, so that a user can quickly use the required functions, the response speed of the electronic device after cold start is provided, and the start experience of the user is improved.

As shown in fig. 8, the startup scenes of the electronic device include scene a, scene B, scene C, … …, scene N. The starting sequence corresponding to the scene A is a function A, a function B, a function C, a function … … and a function N. If the driver needs to enter the scene X (X is one of A, B, … … and N) during cold start, initializing the driver corresponding to the scene X, starting the function corresponding to the scene X, initializing the drivers corresponding to other scenes and starting the functions corresponding to other scenes.
