Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a multi-system control method, a multi-system control device, equipment and a storage medium, and aims to solve the problem of conflict caused by the fact that multiple systems need to control a display system.
Fig. 1 is a flowchart illustrating a multi-system control method according to an exemplary embodiment of the present invention. As shown in fig. 1, the multisystem control method provided by the present invention includes the following steps:
s101, respectively obtaining the current corresponding working state of each subsystem, wherein the only first subsystem in the foreground state exists in the multiple systems at the same time.
More specifically, fig. 2 is a schematic structural diagram of a dual system corresponding to the multi-system control method shown in the embodiment of fig. 1. As shown in fig. 2, the multisystem includes at least two subsystems 201, wherein each subsystem 201 is connected to the first display system 202, so that each subsystem 201 can control the first display system 202.
The working state of the subsystems is a foreground state or a background state, and the only subsystem in the foreground state exists in the multiple systems at the same time and is marked as a first subsystem, and the rest subsystems are in the background state.
For example: the method comprises the steps that multiple systems are configured in a terminal device, wherein the multiple systems comprise an Android system and an autonomous development system, a display system of the terminal device comprises a display driver positioned at a bottom Layer, a display driver package of a Hardware Abstraction Layer (HAL) and display control of a Framework Layer (Framework Layer). The Android system and the autonomous research and development system can control a display system of the terminal device.
And respectively acquiring the working states of the Android system and the autonomous research and development system, wherein if the working state of the Android system is a foreground state, the working state of the autonomous research and development system is a background state. And if the working state of the autonomous research and development system is a foreground state, the working state of the Android system is a background state. So as to ensure that the only subsystem in the foreground state exists in the multiple systems.
S102, the first subsystem is used for controlling the first display system.
More specifically, the first subsystem in the foreground state only in the multiple systems controls the first display system, and the subsystem in the background state in the multiple systems stops controlling the first display system.
For example: if the working state of the Android system is a foreground state, the Android system controls the first display system, and the autonomous research and development system stops controlling the first display system to display the content to be displayed by the Android system. If the working state of the autonomous research and development system is the foreground system, the autonomous research and development system controls the first display system, and the Android system stops controlling the first display system to display the content to be displayed by the autonomous research and development system.
In the multisystem control method provided by this embodiment, the working state of each subsystem in the multisystem is acquired to determine the only subsystem in the foreground state, the subsystem is set as the first subsystem, and the first subsystem is set to control the first display system, so as to solve the problem of conflict caused by the fact that the display systems need to be controlled by a plurality of existing subsystems.
Fig. 3 is a flowchart illustrating a multi-system control method according to yet another exemplary embodiment of the present invention. As shown in fig. 3, the multisystem control method provided in this embodiment includes the following steps:
s301, the current corresponding working state of each subsystem is respectively obtained, and the only first subsystem in the foreground state exists in the multiple systems at the same time.
And S302, after receiving the switching signal, interchanging the working states between the two subsystems, wherein one subsystem of the two subsystems is a first subsystem.
More specifically, in order to realize that each subsystem can control the first display system, one subsystem in the background state is arbitrarily selected from the multiple systems, and the working state of the subsystem in the background state is exchanged with the working state of the subsystem in the foreground state, so as to update the subsystem in the foreground state, and update the first subsystem.
For example: the multiple systems comprise an Android system and an autonomous research and development system. If the Android system is in a foreground state, the autonomous research and development system is in a background state, after receiving a switching signal, the Android system is switched to the background state, the autonomous research and development system is switched to the foreground state, and the first subsystem is the autonomous research and development system.
If the Android system is in the background state, the autonomous research and development system is in the foreground state, after receiving the switching signal, the Android system is switched to the foreground state, the autonomous research and development system is switched to the background state, and the first subsystem is the Android system.
And S303, the first subsystem is used for controlling the first display system.
More specifically, after updating the first subsystem, the first subsystem is caused to control the first display system to cause the updated first subsystem to display the content to be displayed.
For example: if the first subsystem is updated to the autonomous research and development system after receiving the switching signal, the autonomous research and development system controls the first display system to display the content to be displayed by the autonomous research and development system. And if the first subsystem is updated to the Android system after the switching signal is received, the Android system controls the first display system to display the content to be displayed by the Android system.
In the multisystem control method provided in this embodiment, after the current working state corresponding to each subsystem is obtained, the working state of the subsystem in the foreground state and the working state of the subsystem in the background state are interchanged to update the first subsystem, so that each subsystem alternately controls the first display system, and the technical problem of conflict caused by the fact that a plurality of subsystems in the existing multisystem need to control the display systems is solved.
Fig. 4 is a flowchart illustrating a multi-system control method according to yet another exemplary embodiment of the present invention. As shown in fig. 4, the multisystem control method provided in this embodiment includes the following steps:
s401, the current corresponding working state of each subsystem is respectively obtained, and the only first subsystem in the foreground state exists in the multiple systems at the same time.
S402, the first thread circularly calls a waiting instruction so as to enable the first thread to be in an idle state.
More specifically, in the multisystem, each subsystem is provided with a thread, and a first thread calls a waiting instruction through circulation to enable the first thread to be in an idle state so as to enable the first thread to wait for receiving a first switching signal.
For example: the multisystem comprises an Android system and an autonomous research and development system, wherein the Android system is provided with a first display thread 1, the autonomous research and development system is provided with a second display thread 2, the first display thread 1 and the second display thread 2 both call a waiting instruction, so that the first display thread 1 and the second display thread 2 are both in an idle state, and the first display thread 1 and the second display thread 2 both wait for receiving a switching signal.
When the Android system or the autonomous research and development system is in a foreground state currently, a program waitForFbSleep can be called, so that the first display thread 1 and the second display thread 2 are in an idle state. When the Android system or the autonomous research and development system is in a background state currently, a program waitForFbWake can be called to enable the first display thread 1 and the second display thread 2 to be in an idle state.
And S403, when the first thread receives the first switching signal, interchanging the working states between the two subsystems, wherein one subsystem of the two subsystems is the first subsystem.
More specifically, normally, the switching signal exists in pairs, and if a thread of one subsystem in the background state receives the switching signal, a thread of another subsystem in the foreground state also receives the switching signal. And the thread receiving the switching signal controls the corresponding subsystem to switch the working state of the subsystem so as to update the first subsystem.
For example: the first display thread 1 and the second display thread 2 both receive the switching signal, the Android system is controlled by the first display thread 1, the autonomous research and development system is controlled by the second display thread 2, and the interchange of working states between the Android system and the autonomous research and development system is achieved.
S404, the first subsystem is used for controlling the first display system.
More specifically, under the monitoring of the first thread, the working state is exchanged between the subsystem in the foreground state and the subsystem in the background state, and after the working state is exchanged, the first subsystem controls the first display system.
In the multisystem control method provided in this embodiment, the first thread monitors whether the switching signal is received, and if the switching signal is received, the corresponding subsystems are controlled to perform work state interchange, so as to update the first subsystem, and each subsystem alternately controls the first display system, thereby solving a conflict problem caused by the fact that the display systems need to be controlled by a plurality of existing subsystems.
Fig. 5 is a flowchart illustrating a multi-system control method according to yet another exemplary embodiment of the present invention. As shown in fig. 5, the multi-system control method provided in this embodiment includes:
s501, the current corresponding working state of each subsystem is respectively obtained, and the only first subsystem in the foreground state exists in the multiple systems at the same time.
S502, the first thread circularly calls a waiting instruction so as to enable the first thread to be in an idle state.
And S503, after receiving the switching signal, sending a hardware field frequency signal to the subsystem in the background state in the two subsystems, and releasing the display memory resource by the subsystem in the foreground state.
More specifically, to reduce memory usage, all subsystems in a multi-system share a display memory. In the two subsystems with the work states interchanged, one subsystem is in a foreground state, the other subsystem is in a background state, and after the first thread receives the switching signal, the thread corresponding to one subsystem of the two subsystems controls the subsystem, so that the subsystem releases the display memory resource, and the system is switched to the background state.
In addition, the thread corresponding to the other subsystem of the two subsystems triggers the hardware field frequency signal to send the hardware field frequency signal to the subsystem, so that the other subsystem sends a screen refreshing signal to the display system, and the subsystem is switched to a foreground state.
Because the subsystem in the background state has no display requirement, after the subsystem in the foreground state is switched to the background state, the subsystem does not perform image synthesis, and does not send the synthesized image to the display system any more, and does not occupy display memory resources, so that the subsystem in the foreground state exclusively occupies the display memory, and the subsystem in the foreground state starts to receive a hardware field frequency signal and sends a screen refreshing signal to the display system to control the display system.
For example: the multisystem comprises an Android system and an autonomous research and development system, wherein the Android system is provided with a first display thread 1, and the autonomous research and development system is provided with a second display thread 2. If the Android system is in a foreground state, the autonomous research and development system is in the foreground state, and the first display thread 1 and the second display thread 2 both receive the switching signal, the first display thread 1 controls the Android system by calling a screen release method, so that the Android system releases display memory resources, and the Android system is switched to the background state.
The second display thread 2 controls the autonomous research and development system by calling the screen acquired method, receives the hardware field frequency signal, so that the autonomous research and development system sends a screen refreshing signal to the display system, and the autonomous research and development system is switched to a foreground state.
And S504, the first subsystem is used for controlling the first display system.
More specifically, in order to enable the foreground system to exclusively use the display system, when the display system receives a display command sent by the hardware abstraction layer, it is first determined whether the display command is sent by the subsystem in the foreground state or the subsystem in the background state, and an invalid value is directly returned to the display command sent by the subsystem in the background state, so as to execute the display command of the subsystem in the foreground state.
In the multi-system control method provided by the invention, the subsystem in the foreground state releases display memory resources through the first thread control subsystem, the subsystem in the foreground state is switched to the background state, the subsystem in the background state receives a hardware field frequency signal and sends a screen refreshing signal to the display system, and the subsystem in the background state is switched to the foreground state, so that the first subsystem is updated, the first display system is alternately controlled by each subsystem, and the problem of conflict caused by the fact that the display system needs to be controlled by a plurality of subsystems in the prior art is solved.
