Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
An embodiment of the present application provides a method for controlling an electronic device, as shown in fig. 1, where the method is applied to an operating system, and the method includes:
101. and circularly detecting whether the message exists in the message queue through the dispatcher.
In this embodiment of the present application, an execution subject in each step is an operating system running in an electronic device, where the electronic device may be, but is not limited to: computers, servers, and the like.
When a user controls the electronic equipment through the input equipment of the electronic equipment or other electronic equipment sends information to the electronic equipment through a network, the operating system receives and obtains a corresponding operating instruction; after receiving the operation instruction, the operating system needs to generate a message corresponding to the operation instruction, and adds the newly generated message to the tail of the message queue, so that when the subsequent operating system circularly detects that a message exists in the message queue through the scheduling program, the operating system sequentially executes the operation corresponding to each message according to the sequence of each message in the message queue.
In the embodiment of the application, in order to ensure that operations corresponding to received operation instructions can be executed in time and that the electronic device can be controlled to enter the sleep state in time after all operations corresponding to the operation instructions are executed, the operating system needs to detect whether a message exists in a message queue through a scheduler in a circulating manner.
102a, if the message exists in the message queue, acquiring a queue head message in the message queue through a scheduling program, operating a target thread corresponding to the queue head message according to the queue head message, and deleting the queue head message in the message queue.
The queue head message is the first message in the message queue.
In this embodiment of the present application, when the operating system detects that there is a message in the message queue through the scheduler in a loop manner, the operating system needs to obtain a queue head message in the message queue through the scheduler, and run a target thread corresponding to the queue head message according to the queue head message, so that the target thread executes an operation corresponding to the queue head message, and deletes the queue head message in the message queue.
For the embodiment of the application, in step 102b parallel to step 102a, if no message exists in the message queue, the electronic device is controlled to enter the sleep state.
In this embodiment, when the operating system detects that there is no message in the message queue through the scheduler cycle, the operating system needs to control the electronic device to enter the sleep state.
In the embodiment of the application, an operating system circularly detects whether a message exists in a message queue through a scheduler, and when the operating system circularly detects that the message exists in the message queue through the scheduler, the operating system obtains a queue head message in the message queue through the scheduler and runs a target thread corresponding to the queue head message according to the queue head message so that the target thread executes an operation corresponding to the queue head message and deletes the queue head message in the message queue; when the operating system detects that no message exists in the message queue through the cycle of the scheduler, the operating system needs to control the electronic device to enter a sleep state. Therefore, when the operation instruction is received, the operation system can timely execute the operation corresponding to the operation instruction, and when the operation corresponding to all the operation instructions is executed, the operation system can timely control the electronic equipment to enter the dormant state.
At present, the mainstream operating system generally schedules the application programs according to time slices, and no matter how elaborate the scheduling algorithm adopted by the operating system is, the operating system cannot accurately know whether each application program is really busy or not. Therefore, even if an application is in an idle state, i.e. the application does not need to perform any operation, the operating system still schedules the application in the time slice corresponding to the application unless the application is self-sleeping or suspended.
In order to save the power consumption of the electronic device, the operating system generally controls the electronic device to go to the sleep state when it is determined that all the applications in the running state agree to the sleep state based on a preset algorithm. However, when the number of the applications running in the electronic device is too large, it is difficult to determine that all the applications in the running state agree to the hibernation based on the preset algorithm, and therefore, the difficulty of controlling the electronic device to enter the hibernation state is also high, which results in high power consumption of the electronic device.
In the embodiment of the application, when the operation instruction is received, the operation system can execute the operation corresponding to the operation instruction in time, and when the operation corresponding to all the operation instructions is executed, the operation system can control the electronic device to enter the dormant state in time, so that the idle running of the operation system caused by scheduling the application program according to the time slice can be avoided, and the effect of saving the power consumption of the electronic device to the maximum extent is achieved.
To explain in more detail below, an embodiment of the present application provides another control method for an electronic device, specifically as shown in fig. 2, where the method is applied to an operating system, and the method includes:
201. a message queue is created.
In the embodiment of the application, the operating system needs to create the message queue in advance.
202. And when the operation instruction is received, generating a message corresponding to the operation instruction according to a preset registry, and adding the message to the tail of the message queue.
In the embodiment of the application, after receiving the operation instruction, the operating system needs to generate a message corresponding to the operation instruction according to the preset registry, and add the newly generated message to the tail of the message queue.
Specifically, in this step, the operating system may generate a message corresponding to the operation instruction according to the preset registry in the following manner:
the preset registry records the mapping relation between each operation instruction and the thread unique identifier corresponding to the operation instruction; the thread unique identifier corresponding to any one operation instruction is used for uniquely identifying the thread executing the operation corresponding to the operation instruction.
Firstly, a thread unique identifier corresponding to a newly received operation instruction is searched in a preset registry; secondly, extracting operation content corresponding to the operation instruction from the operation instruction; and finally, generating a message corresponding to the operation instruction according to the thread unique identifier and the operation content corresponding to the operation instruction, namely the newly generated message comprises the thread unique identifier and the operation content corresponding to the operation instruction.
203. And circularly detecting whether the message exists in the message queue through the dispatcher.
In step 203, it may refer to the description of the corresponding part in fig. 1 for the scheduler to circularly detect whether there is a cancellation in the message queue, and this embodiment of the present application will not be described again here.
204a, if the message exists in the message queue, acquiring a queue head message in the message queue through a scheduling program, operating a target thread corresponding to the queue head message according to the queue head message, and deleting the queue head message in the message queue.
In this embodiment of the present application, when the operating system detects that there is a message in the message queue through the scheduler in a loop manner, the operating system needs to obtain a queue head message in the message queue through the scheduler, and run a target thread corresponding to the queue head message according to the queue head message, so that the target thread executes an operation corresponding to the queue head message, and deletes the queue head message in the message queue.
Specifically, in this step, the operating system may run the target thread corresponding to the head-of-queue message according to the head-of-queue message in the following manner:
the queue head message comprises a thread unique identifier and operation content corresponding to the queue head message.
Firstly, determining a target thread corresponding to a queue head message according to a thread unique identifier corresponding to the queue head message; secondly, calling an entry function corresponding to the target thread so as to start the target thread; and finally, sending the operation content corresponding to the queue head message to the target thread so that the target thread executes the operation corresponding to the operation content contained in the queue head message.
Further, in the embodiment of the present application, in order to prevent the target thread from consuming a long time to execute the operation corresponding to the operation content included in the queue head message, thereby affecting the operation corresponding to the other messages in the execution message queue, the operating system sends the operation content corresponding to the queue head message to the target thread, so that after the target thread starts to execute the operation corresponding to the operation content, it is required to monitor whether the target thread executes the operation corresponding to the operation content within a preset time duration, and if the target thread executes the operation corresponding to the operation content within the preset time duration, the target thread is immediately closed; if the target thread does not execute the operation corresponding to the operation content within the preset time length, determining the non-executed operation content (namely the non-executed operation content at this time) according to the execution state of the target thread executing the operation corresponding to the operation content, generating an update message corresponding to the target thread according to the non-executed operation content and the thread unique identifier corresponding to the target thread, and adding the update message to the tail of the message queue, so that the target thread can continue to execute the operation corresponding to the non-executed operation content when the update message becomes a head of queue message in the following process.
For the embodiment of the present application, in step 204b parallel to step 204a, if there is no message in the message queue, the electronic device is controlled to enter the sleep state.
In this embodiment, when the operating system detects that there is no message in the message queue through the scheduler cycle, the operating system needs to control the electronic device to enter the sleep state.
Specifically, in this step, the operating system may control the electronic device to enter the sleep state in the following manner:
the electronic equipment comprises a plurality of pieces of first hardware and a plurality of pieces of second hardware; the method includes the steps of obtaining the use frequency of each piece of hardware in the electronic equipment in advance, determining N pieces of hardware with lower use frequencies as first hardware, and determining the rest pieces of hardware as second hardware, wherein the first hardware is the hardware with lower use frequencies in the electronic equipment, the second hardware is the hardware with higher use frequencies in the electronic equipment, and N is a positive integer.
Firstly, starting an interrupt program; secondly, controlling the scheduling program and the first hardware to enter a dormant state; finally, after the scheduler and the plurality of first hardware enter the sleep state for more than a preset time, controlling the plurality of second hardware and the operating system to enter the sleep state, at this time, only the interrupt program is in the running state, wherein the preset time may be, but is not limited to: 60 seconds, 2 minutes, 5 minutes, etc.
Further, in this embodiment of the application, after the electronic device enters the sleep state, when the user operates the electronic device through the input device of the electronic device again, and the other electronic device sends information to the electronic device or the local clock of the electronic device is automatically woken up, so that when the interrupt program receives the interrupt signal, the interrupt program needs to wake up the operating system and the scheduling program, so that the operating system generates an interrupt message corresponding to the interrupt signal according to the preset registry, and runs the target thread corresponding to the interrupt message according to the interrupt message, so that the target thread corresponding to the interrupt message executes an operation corresponding to the interrupt message.
It should be noted that, in the process that the operating system runs the target thread corresponding to the interrupt message according to the interrupt message, if other operation instructions are received, a message corresponding to a newly received operation instruction needs to be generated, and the newly generated message is added to the tail of the message queue, so that when the subsequent operating system circularly detects that a message exists in the message queue through the scheduler, the operation corresponding to each message is sequentially executed according to the sequence of each message in the message queue; if no other operation instruction is received, the electronic device needs to be controlled to enter the sleep state again after the target thread corresponding to the interrupt message executes the operation corresponding to the interrupt message.
In order to achieve the above object, according to another aspect of the present application, an embodiment of the present application further provides a storage medium, where the storage medium includes a stored program, and when the program runs, a device on which the storage medium is located is controlled to execute the control method of the electronic device described above.
