Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides a control method for quick start, which can be applied to the starting process of electronic equipment to shorten the starting time of the electronic equipment.
Specifically, referring to fig. 1, a flowchart of a fast-start control method provided in an embodiment of the present application may include the following steps:
S101, obtaining control information for starting the electronic equipment.
The control information may include control trigger information for starting the electronic device, for example, key information of a power key of the electronic device, and start trigger information of a touch screen of the electronic device, and correspondingly, if the electronic device is started through biometric information, for example, the electronic device is started through fingerprint information of a user, the control information may be received fingerprint trigger information. On the other hand, the control information may also be the start of hardware of the electronic device and the start of a system, and specifically, the control information may include control information for hardware such as a motherboard, a graphics card, a processor, and the like of the electronic device, and control information for starting an operating system of the electronic device.
The starting of the electronic device refers to the starting of state switching of the electronic device, for example, the electronic device is switched from a first state to a second state, the first state may be a power-off state of the electronic device, and the second state may be a power-on state of the electronic device, that is, the starting of the electronic device refers to the state of the electronic device from power-off to power-on, and may also be a restarting state after power-off of the electronic device.
In order to quickly obtain the control information of the starting electronic device, in one implementation manner of the embodiment of the application, a virtual device or a virtual thread can be created in a kernel layer of an operating system of the electronic device, and the virtual device or the virtual thread is only used for monitoring the control information of the starting electronic device, specifically, the virtual device or the virtual thread can be used for monitoring and receiving key messages of a switch key of the electronic device, so as to obtain the key control information of the starting electronic device. The control information of the electronic equipment is started through the virtual equipment or the virtual thread, so that the control information can be directly broadcast to a starting system at the bottom layer of the electronic equipment, the controller does not need to be transferred layer by layer through other threads, and the controller is not influenced by other information.
S102, obtaining a target frequency parameter based on the control information and setting a target frequency range of a processor of the electronic device.
S103, controlling a scheduler of a processor to schedule at least one target process based on control information, and setting the at least one target process to a target kernel of the processor.
Typically, an electronic device will operate with a certain frequency parameter, where the frequency parameter mainly refers to a frequency parameter of a processor (such as a central processing unit, CPU) of the electronic device, and may also be referred to as a main frequency of the processor of the electronic device, that is, an operating frequency (a number of synchronous pulses occurring in 1 second) during operation of the processor. The greater the frequency parameter of the processor, the faster the processing speed of the electronic device.
After the control information of the starting electronic device is obtained, the target frequency parameter can be obtained based on the preset frequency parameter corresponding to the target state which needs to be reached by the starting electronic device in the control information. For example, the target frequency parameter may be a frequency parameter during an initial default startup of the electronic device, or may be a frequency initial value higher than the lowest frequency of the processor. The control information for starting the electronic device is different, and the corresponding target frequency parameters can also be different. For example, from a complete shutdown state to a startup state, the number of corresponding control hardware in the control information is relatively small, the corresponding target frequency parameter may be relatively small, if the restart process is performed after shutdown, the corresponding hardware and system threads to be started are relatively large, and the corresponding target frequency parameter may be relatively large. It is also possible to determine the target frequency parameter, i.e. the highest frequency achievable by the processing core, as the target frequency parameter based on the performance of the respective processing core to which the electronic device processor corresponds.
In the embodiment of the application, after the target frequency parameter is obtained, the target frequency range of the processor of the electronic equipment needs to be further set, wherein the minimum value of the target frequency range is the target frequency parameter, namely, the frequency of the processor of the electronic equipment can be raised, so that the running speed of the processor of the electronic equipment is improved, and the processor can respond to the control information for starting the electronic equipment more quickly.
At the same time, it is also necessary to control a scheduler of a processor based on a controller to schedule at least one target process and set the at least one target process to a target kernel of the processor. The processes to be executed in the process of starting the electronic device can be determined based on the control information, and key processes are determined as target processes in the threads, for example, the target processes can be determined according to the execution sequence of each process, and the target processes can also be determined according to the importance degree of each process on the starting of the electronic device. Specifically, the process of calling the display interface, the process of starting the personalized configuration of the user, the process of starting the sound card and the like can be included in the starting electronic equipment. When the electronic equipment is started, in order to achieve the experience effect of quick starting of a user, a process of calling the display interface can be used as a target process, so that the processor can process the process preferentially and load the display interface preferentially, and the user can obtain the experience effect of quick starting. For further rapid start purposes, at least one target process may be set to a target kernel of the processor. Such that in response to the control information, the processor operates at a target frequency range and at least one target process operates on a target kernel of the processor.
The processing cores (also referred to as cores) are separate execution units within the electronic device processor that are physically separate, having separate resources. Processors of current electronic devices are typically multi-core processors, typically having 4 processing cores or 8 processing cores. The target core in the embodiment of the application refers to a processing core with better performance in a processor, and can be a processing core with better performance parameters as the target core, wherein the performance parameters can include a processing rate parameter, a load parameter, a working frequency or the like. And the target process is operated on the target kernel, so that the operation rate of the target process can be further improved. And the processor operates in a target frequency range, so that the frequency of the processor is increased as a whole, the processing speed of the processor is further increased, and the starting speed of the electronic equipment is further increased.
In an embodiment of the present application, the target process includes at least one system process or at least one system service in which an operating system of the electronic device is in a running state. An Operating System (OS) is a computer program that manages computer hardware and software resources. When the operating system is in an operating state, a corresponding system process or system service is executed. A system process or a system service that best matches the control information of the currently started electronic device may be selected as the target process. The system process refers to an application program running in the system, and may include a user interface loading process, a resource management process, a session management process, and the like. System services (SYSTEM SERVICES) refer to programs, routines, or processes that perform specified system functions in order to support other programs, particularly the underlying (near hardware) programs. When a service is provided through a network, the service can be published in an Active Directory, thereby facilitating service-centric management and use.
In one implementation of the embodiment of the present application, the setting at least one target process to a target kernel of a processor includes:
Setting a parameter value of affinity for the at least one target process such that the at least one target process has a first priority when running on a target kernel of the processor.
Wherein affinity (affinity) of a target process is the tendency of a process to run on a given processing core for as long as possible without being migrated to other processing cores. Taking Linux operating system as an example, all processes have a related data structure, and the data parameters representing the affinity of the data structure of the target process can be changed through an API (Application Programming Interface, application program interface) provided by the Linux kernel, so as to complete the process of setting the parameter values of the affinity of the target process. Therefore, the target process has the first priority when running on the target kernel of the processor, wherein the first priority is the highest priority, namely, the target process cannot migrate to other processing kernels due to other processes or changes of the load of the target kernel when running on the target kernel. And further, the target process runs on the target kernel with better processing performance all the time.
Specifically, setting the parameter values of affinity for at least one target process includes: and setting parameter values of affinities for at least one target process based on the control information and the state information corresponding to the target process. The device state of the electronic device to be started and entered can be obtained based on the control information, and meanwhile, different state information of the target process can be obtained under different conditions, for example, the running state of the target process can be from a non-running state to a running state, can be always in the running state, and the like. Thereby setting a parameter value capable of satisfying the affinity of the current state information of the target process to ensure the first priority of the target process running on the target kernel.
In another implementation manner of the embodiment of the present application, the fast start control method further includes:
Obtaining a time range based on the control information;
The time range of the processor is set.
Wherein the time range is used to indicate a duration that the processor is operating in the target frequency range. The target frequency range is a range with a higher frequency parameter value corresponding to the processor of the electronic device, and if the processor runs with the frequency parameter in the target frequency range all the time, the power consumption of the electronic device is increased. Therefore, the time range of the corresponding processor can be set, namely, the frequency corresponding to the processor at the side of the electronic equipment in the time range is the frequency parameter in the target frequency range, so that the processing speed of the processor can be improved, and the power consumption of the electronic equipment can be reduced. The time frame may be obtained directly based on performance parameters of the electronic device processor. The time range may also be obtained based on control information, where the control information corresponds to a start state reached by the control electronic device, and the number or types of target processes corresponding to different start states of the electronic device may be different, and the execution duration may be different, so that the time range may be set to a duration capable of completing the target process corresponding to the control information.
In one embodiment, the setting the target frequency range of the processor of the electronic device includes: the target frequency range of the processor is set by a quality of service QoS service layer so that the processor locks with the target frequency range.
And, said setting said time range of the processor comprises: the time range of the processor is set by a QoS service layer such that the processor is locked to operate within the time range at a target frequency range.
QoS (Quality ofService ) refers to the ability of a network to utilize various underlying technologies to provide better service capabilities for a given network communication. The QoS service layer is a provisioning layer for information transfer and sharing between the network and users and between users communicating with each other over the network, which may provide resource scheduling and management. Thus, the target frequency range of the processor and the corresponding time range may be set by the QoS service layer. When the QoS service layer sets the target frequency range and the corresponding time range, the QoS service layer is equivalent to the management layer, for example, the QoS service layer may receive setting parameters of multiple target frequency ranges, and may determine the final target frequency range based on priorities corresponding to the received setting parameters of multiple target frequency ranges, and combine the performance of the current processor, so that it is not necessary to respond to the setting of other processes any more, so that the processor locks with the target frequency range, and avoids restoring to the lowest frequency initial value. Thereby ensuring the processing speed of the processor during the start-up of the electronic device. And the time range of the processor is set through the QoS service layer, so that the processor is locked in the time range when running in the target frequency range, and the processing speed and the processing power consumption of the processor in the time range are ensured not to be excessively high.
Specifically, the target kernel of the processor to which the at least one target process is set is a first type kernel in the processor, and the processing performance of the first type kernel is better than that of a second type kernel in the processor.
The cores of the processor can be divided according to the performance parameters of the cores in the processor, the cores with higher performance parameters are determined to be the first type cores, and the rest cores are determined to be the second type cores. The performance parameter may be included in a processing rate parameter, a load parameter, or an operating frequency parameter, among others. For example, a corresponding processing rate parameter threshold is set, the cores corresponding to the threshold are more than the threshold are the first type cores, and the rest cores are the second type cores. To characterize that the target process is running on a first type of kernel with better performance.
The following describes a fast start control method in the embodiment of the present application by taking a process flow of starting up an electronic device with an operating system as Android (Android) as an example. Android (Android) is an operating system based on free and open source code of the Linux kernel (without GNU components).
Fig. 2 is a schematic diagram of a process flow of starting up an electronic device according to an embodiment of the present application.
In fig. 2, a User space (User space) is a running space of a User program, which may run an android System desktop Launcher 201 (also referred to as a desktop UI of the android System), and may also run a System User interface program 202 (System UI) and a System service 203 (SYSTEM SERVER). Also included in FIG. 2 is kernel space (KERNEL SPACE), which is the running space of the Linux kernel. The kernel space can execute any command and call all resources of the system; the user space can only execute simple operation, can not directly call the system resource, and can send out instructions to the kernel through the system interface.
In fig. 2, the kernel space monitoring process 204 may be used to monitor the start event of the electronic device, and in particular, the monitoring process may be to create a virtual device in the Linux kernel space, and monitor the start event of the electronic device through the virtual device. The power key 206 or the start control instruction of the electronic device generated by the touch screen 207 may further be obtained through the device input system 205.
When a start event of the electronic device is monitored, that is, after control information for starting the electronic device is obtained, the control information is transmitted to a processor frequency adjustment process 208 and a scheduling process 209 corresponding to the scheduler, and then the processor frequency adjustment process determines a target frequency range of the processor, and a target kernel capable of realizing the target frequency range can be determined based on the target frequency range. The target process is then determined by the scheduler, such as by determining the system service and the system process as the target process. After the target frequency range, the target process and the target kernel are obtained, the information may be stored in the kernel process 210, and when the processor runs the target process, the corresponding running result may be transmitted to the user space process 211.
And then, transmitting the running results of the target process into the Init 212, zygote and the Dalvik VM 214 layer by layer, transmitting the running results to the user space by DalvikVM, and generating a final display result by a corresponding process program in the user space, wherein if the target process is rendering of the user interface, the user interface is generated by the user interface program in the user space and displayed on the electronic device so as to complete the starting process of the electronic device. Wherein Init, zygate and DalvikVM are all universal connection processes for kernel space and user space in the android system. Specifically, init is a user-level process initiated by the kernel, zygote is a core process created by the entire system, and DalvikVM is a virtual machine that interacts with the user space.
It should be noted that, when the target frequency range is set, the target frequency range corresponding to the processor may be set, or the target frequency range corresponding to the processor kernel may be set through the QoS layer, the frequency ranges that may be achieved by different kernels are different, the frequency ranges corresponding to each kernel may be set respectively in combination with the characteristics of the kernels, and the kernel with a higher frequency range is selected as the target kernel to run the determined target process. The target frequency range is mainly set to be the minimum value of the target frequency range, namely, the minimum value is a target frequency parameter determined based on the performance of the processor core. And setting a time range, locking the time range of the processor, and preventing other scheduling strategies in the QoS layer from influencing the target frequency range, namely avoiding restoring the frequency of the processor to the original minimum frequency initial value.
Further, in the kernel space, parameter values of affinities of the respective processes are set, and the target process is scheduled to be executed by a target kernel (which may be a kernel with optimal performance) based on the parameter values. When the android system starts the service, the corresponding process needs to be operated, and weighting calculation can be performed on each process through the priority parameter and the control information corresponding to each process by the kernel scheduler, so that a target process, such as the target process, is determined to serve as the system, and the target process is guaranteed to be operated preferentially, namely, is scheduled to the target kernel to be operated.
According to the control method for quick start provided by the embodiment of the application, the target frequency range of the processor can be adjusted, so that the processor is triggered on the kernel thread, and the optimal target kernel can be selected to run according to the adjusted frequency by determining the target process corresponding to the user space, thereby improving the starting speed of the electronic equipment. Furthermore, the target process is scheduled to the target kernel with better performance, so that the processing efficiency is further improved, the starting process of the electronic equipment is optimized by the preferential operation of the target process, and the starting time is shortened.
