Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The electronic equipment can be provided with double systems, the systems are respectively arranged in respective containers, the two containers are mutually independent, and users can carry out different operations in different systems according to own preferences. When the dual system is needed, the dual system can be selected to be started; when only one system needs to be used or the system needing to be used occupies more memory space, the other system in the dual systems can be selected to be closed, so that the system needing to be used can be ensured to run more smoothly. The shut down system may be restarted when it is desired to reuse the shut down system.
In one example, the electronic device configures a respective container for each of the dual systems; fig. 1 is an interaction diagram of a system shutdown method provided in this embodiment. As shown in fig. 1, when one of the systems needs to be closed, a close instruction is initiated through a Rootns field (for example, the close instruction is an lxc-stop instruction), and then a container corresponding to the system is directly closed (where container 1 is a container corresponding to a first system, and container 2 is a container corresponding to a second system); as the container is closed, the system in the container is directly closed. For example, as shown in fig. 1, the roots field sends an lxc-stop instruction to the container 1 corresponding to the first system that needs to be closed, and then the container 1 is closed according to the lxc-stop instruction, and the first system in the container 1 is closed due to the direct closing of the corresponding container 1.
However, in the above process, the container corresponding to the system to be closed is directly closed, so that the system in the container is closed, which may cause some running programs or data in the system to be unable to be stored, and may cause data to be damaged or unable to be stored, thereby causing data loss; and the operation of accessing the disk in the system can be directly terminated, thereby causing disk abnormity and prolonging the next startup time. In addition, a hardware device (e.g., camera hardware) shared in the dual system may not be normally used in the system that is not closed because of the operation of directly closing the container.
The application provides a system shutdown method, equipment and storage medium based on dual systems, which aim to solve the above technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a system shutdown method based on dual systems according to an embodiment of the present disclosure, where the method is applied to an electronic device, and a kernel, a root namespace (roots) domain, a first system, and a second system run in the electronic device. As shown in fig. 2, the method includes:
101. the kernel acquires a closing instruction, wherein the system closing instruction comprises an identifier of a system to be closed, and sends the closing instruction to a Roots domain.
Exemplarily, two Android systems, namely a first system and a second system, are installed in the electronic device; and, a kernel and a Rootns domain run in the electronic device. The Rootns domain, the first system and the second system can mutually listen to each other through the kernel. When a user needs to close a certain temporarily unneeded system, a system closing instruction can be sent to the kernel through a system closing button in the currently used system, and the system closing instruction comprises an identifier of the system to be closed. And after the kernel acquires the closing instruction, sending the closing instruction to the Rootns domain. For example, when a first system in the electronic device needs to be turned off, a button for turning off the background system is provided on the operation interface of a second system of the electronic device. After clicking a button of 'closing the background system', the user sends a closing instruction to the kernel. The close instruction includes a shutdown instruction (shutdown) and an attribute identifier (vp 1) of the first system. The kernel sends a close indication to the Rootns field after receiving the close command.
For example, when the second system in the electronic device needs to be turned off, there is a button for turning off the background system on the operation interface of the first system of the electronic device. After clicking a button of 'closing the background system', the user sends a closing instruction to the kernel. The close instruction includes a shutdown instruction (shutdown) and an attribute identifier (vp 2) of the second system. The kernel sends a close indication to the Rootns field after receiving the close command.
102. The Rootns field associates the attribute value with the identifier of the system to be closed, and sends indication information to the kernel, wherein the indication information comprises the attribute value associated with the identifier of the system to be closed.
Illustratively, when a first system in the electronic device needs to be closed, after the shutdown instruction sent by the core is received by the Rootns domain, the attribute value in the Rootns domain is associated with the identifier in the system to be closed in the shutdown instruction, that is, the attribute value of sys. Wherein the indication information contains an attribute value (vp 1) of the system identification to be shut down.
Illustratively, when a second system in the electronic device needs to be closed, after the shutdown instruction sent by the core is received by the Rootns domain, the attribute value in the Rootns domain is associated with the identifier in the system to be closed in the shutdown instruction, that is, the attribute value of sys. Wherein the indication information contains an attribute value (vp 2) with a system identification of shutdown.
103. When the first system monitors that the identifier of the system to be closed, which is associated with the attribute value, is the identifier of the first system, the init process is modified, so that the init process stops the data processing process of the first system and closes the first system after storing the data.
Exemplarily, when a first system in the electronic device needs to be closed, the first system monitors a change in the kernel through a poll mechanism, and waits for a readable event to occur in the kernel, where the readable event includes indication information sent by a roots field to the kernel, and the indication information includes an attribute value of a system identifier to be closed. After the Rootns domain sends the associated indication information to the kernel, the first system monitors the indication information sent by the Rootns in the kernel, and a poll mechanism in the first system reads the indication information sent by the Rootns from the kernel. And if the identifier of the system to be closed in the indication information is the identifier of the first system (vp 1), the first system modifies the init process. And the first system sequentially saves the data processing process in the first system by executing the modified init process, sequentially releases the memory of the hardware on the kernel, and closes the first system after saving the data.
104. And when the second system monitors that the identifier of the system to be closed, which is associated with the attribute value, is the identifier of the second system, modifying the init process so as to enable the init process to stop the data processing process of the second system and close the second system after storing the data.
Illustratively, when a second system in the electronic device needs to be closed, the second system monitors a change in the kernel through a poll mechanism, and waits for a readable event to occur in the kernel, where the readable event includes indication information sent by a Rootns field to the kernel, and the indication information includes an attribute value of a system identifier to be closed. After the Rootns domain sends the associated indication information to the kernel, the second system monitors the indication information sent by the Rootns in the kernel, and the poll mechanism in the second system reads the indication information sent by the Rootns from the kernel. And if the identifier of the system to be closed in the indication information is the identifier of the second system (vp 2), the second system modifies the init process. And the second system sequentially saves the data processing process in the first system by executing the modified init process, sequentially releases the memory of the hardware on the kernel, and closes the second system after saving the data.
In this embodiment, after the kernel obtains the instruction to close the system, the kernel sends the instruction to close the system to the Rootns domain, where the instruction to close the system and the instruction to close the system sent by the background both include the attribute value of the identifier of the system to be closed. After receiving the instruction sent by the kernel to close the system, the Rootns field associates the attribute value of the Rootns field with the identifier of the system to be closed, and sends indication information to the kernel, wherein the indication information comprises the attribute value associated with the identifier of the system to be closed. The first system monitors the change information in the kernel, after monitoring and reading the indication information sent to the kernel by the Roots domain, if the system identifier to be closed in the indication information is found to be the identifier of the first system, the init process is modified, so that the init process stops the data processing process of the first system and closes the first system after storing the data, and the Roots domain and the second system do not execute the modified init process. And if the second system monitors and reads the change information in the kernel, when the identifier of the system to be closed in the indication information sent to the kernel by the Roots domain is the identifier of the second system, modifying the init process so as to stop the data processing process of the second system and close the second system after storing the data by the init process, wherein the modified init process is not executed by the Roots domain and the first system. When the system in the dual system is closed by using the method, the system to be closed executes a normal shutdown process, namely, closing information is broadcasted to the system to be closed, processes such as a data processing process and the like in the system are stopped in sequence, data is stored in sequence, and in addition, the hardware equipment closes the system to be closed after releasing the memory occupied in the kernel in sequence. The method has the advantages that the process in the system to be closed can be stopped in sequence, the disk is not abnormal due to sudden access stop, and the phenomenon that the next startup time is prolonged is avoided. The data in the system to be closed is written into the disk in time and stored, the shared hardware in the two systems releases the memory occupied by the kernel in sequence, so that the hardware can be normally closed in the system to be closed, and the unclosed system can normally use the shared hardware in the two systems.
Fig. 3 is a schematic flowchart of another dual-system-based system shutdown method according to an embodiment of the present disclosure, where the method is applied to an electronic device, and a kernel, a root namespace (roots) domain, a first system, and a second system run in the electronic device. As shown in fig. 3, the method includes:
201. the kernel acquires a closing instruction, wherein the system closing instruction comprises an identifier of a system to be closed, and sends the closing instruction to a Roots domain.
Exemplarily, a dual system, a first system and a second system, respectively, is installed in the electronic device; and, a kernel and a Rootns domain run in the electronic device.
This step can be referred to as step 101 in fig. 2, and is not described again.
202. And the Rootns field modifies the attribute value into an identifier of the system to be closed and sends indication information to the kernel, wherein the indication information comprises the attribute value associated with the identifier of the system to be closed.
For example, in an electronic device with two systems installed therein, if a first system in the electronic device needs to be closed, after the Rootns domain receives a close instruction sent by the core, an attribute value in the Rootns domain is modified to an identifier of a system to be closed, that is, a sys. Wherein the indication information contains an attribute value (vp 1) associated with the system identification to be shut down.
For example, in an electronic device with two systems installed, if a second system in the electronic device needs to be closed, after the Rootns domain receives a close instruction sent by the core, an attribute value in the Rootns domain is modified to an identifier of a system to be closed, that is, a sys. Wherein the indication information comprises an attribute value (vp 2) associated with the system identification with shutdown.
203a, when monitoring that the identifier of the system to be closed associated with the attribute value is the identifier of the first system, the first system modifies first preset attribute information in the first system according to the identifier of the system to be closed associated with the attribute value, wherein the modified first preset attribute information includes the identifier of the system to be closed.
Illustratively, the first system may listen for information changes stored in the kernel through the poll mechanism. When the Rootns domain sends the indication information of the attribute modification information to the kernel (wherein the indication information includes attribute value information associated with the identifier of the system to be closed), after monitoring the indication information sent by the Rootns domain in the kernel by a poll mechanism in the first system, the first system reads the indication information sent by the Rootns domain to the kernel through the poll mechanism, at this time, if the identifier of the system to be closed is the identifier vp1 of the first system, the first preset attribute information of the first system is modified according to the read indication information, and the first preset attribute information of the first system is modified into (shutdown, vp 1).
204a, the second system modifies second preset attribute information in the second system according to the identifier of the first system, wherein the modified second preset attribute information comprises the identifier of the first system.
Illustratively, the second system may listen for information changes stored in the kernel through the poll mechanism. When the Rootns domain sends the indication information of the attribute modification information to the kernel (wherein the indication information comprises attribute value information associated with the identifier of the system to be closed), after a poll mechanism in the second system monitors the indication information sent by the Rootns domain in the kernel, the second system can read the indication information sent by the Rootns domain to the kernel through the poll mechanism, at this time, if the identifier of the system to be closed is the identifier vp1 of the first system, the second preset attribute information of the second system is modified according to the read indication information, that is, the second preset attribute information of the second system is modified into (shutdown, vp 1).
205a, the Rootns domain receives third preset attribute information fed back by the first system through the kernel, wherein the third preset attribute information represents that the first system is to be closed; the Rootns field sends a first closing request to the kernel and receives a first closing command fed back by the kernel.
Illustratively, after the first system modifies the attribute of the first system according to the indication information in the kernel, the first system modifies third preset attribute information in the first system (wherein the third preset attribute information indicates that the first system is to be closed), that is, the attribute value of "sys. After the third preset attribute information is modified, the first system sends the third preset attribute information to the kernel; after monitoring third preset attribute information sent by the first system in the kernel, a poll mechanism in the Rootns domain acquires an attribute value represented by the third preset attribute information from the kernel ("sys. Upon receiving the attribute "sys. Vp1.Shutdown = ready", trigger in the Rootns domain sends a first shutdown request to the kernel, where the first shutdown request represents a request to close the container 1 in which the first system is located. After receiving the first close request, the kernel sends a first close command to the celld service in the Rootns domain, where the first close command represents a command to close the container 1 where the first system is located.
206a, the first system modifies the init process so that the init process stops the data processing process of the first system and closes the first system after the data is stored.
Illustratively, the init process is modified after the first system modifies the attribute of the first system according to the indication information in the kernel. And the first system closes the processes in the first system in sequence by executing the modified init process, writes the data into a disk, and closes the first system after the data is stored in sequence.
The execution order of the steps 206a and 205a is not limited.
207a, the Rootns field closes the container corresponding to the first system after a preset time according to the first close command.
Illustratively, after the celld service in the Rootns domain receives the first close command sent by the kernel, and waits for the set preset time, the celld service in the Rootns domain calls an instruction lxc-stop to close the container 1 in which the first system is located. Wherein waiting a preset time period ensures that the vessel 1 in which the first system is located is not closed until the first system is completely closed.
203b, when monitoring that the identifier of the system to be closed associated with the attribute value is the identifier of the second system, the second system modifies second preset attribute information in the second system according to the identifier of the system to be closed associated with the attribute value, wherein the modified second preset attribute information comprises the identifier of the system to be closed.
Illustratively, the second system may listen for information changes stored in the kernel through the poll mechanism. When the Rootns domain sends the indication information of the attribute modification information to the kernel (wherein the indication information includes attribute value information associated with the identifier of the system to be closed), after monitoring the indication information sent by the Rootns domain in the kernel, the poll mechanism in the second system can read the indication information sent by the Rootns domain to the kernel, at this time, if the identifier of the system to be closed is the identifier vp2 of the second system, the second preset attribute information of the second system is modified according to the read indication information, and the second preset attribute information of the second system is modified into (shutdown, vp 2).
204b, the first system modifies the first preset attribute information in the first system according to the identifier of the second system, wherein the modified first preset attribute information comprises the identifier of the second system.
Illustratively, the first system may listen for information changes stored in the kernel through the poll mechanism. When the Rootns domain sends the indication information of the attribute modification information to the kernel (wherein the indication information includes attribute value information associated with the identifier of the system to be closed), after a poll mechanism in the first system monitors the indication information sent by the Rootns domain in the kernel, the first system can read the indication information sent by the Rootns domain to the kernel through the poll mechanism, at this time, if the identifier of the system to be closed is an identifier vp2 of the second system, the first preset attribute information of the first system is modified according to the read indication information, that is, the first preset attribute information of the first system is modified into (shutdown, vp 2).
205b, the Rootns domain receives fourth preset attribute information fed back by the second system through the kernel, wherein the fourth preset attribute information represents that the second system is to be closed; the Rootns domain sends a second closing request to the kernel and receives a second closing command fed back by the kernel;
illustratively, after the second system modifies the attribute of the second system according to the indication information in the kernel, the second system modifies fourth preset attribute information in the second system (where the fourth preset attribute information indicates that the second system is to be shut down), that is, the attribute value of "sys. After the fourth preset attribute information is modified, the second system sends the fourth preset attribute information to the kernel; after monitoring fourth preset attribute information sent by the second system in the kernel, a poll mechanism in the Rootns domain acquires an attribute value represented by the fourth preset attribute information from the kernel ("sys. Upon receiving the attribute "sys. Vp2.Shutdown = ready", trigger in the Rootns domain sends a second shutdown request to the kernel, where the second shutdown request represents a request to close the container 2 in which the second system is located. After receiving the second close request, the kernel sends a second close command to the celld service in the Rootns domain, where the second close command represents a command to close the container 2 where the second system is located.
206b, the second system modifies the init process so that the init process stops the data processing process of the second system and closes the second system after the data is stored.
Illustratively, the init process is modified after the second system modifies the attribute of the second system according to the indication information in the kernel. And the second system closes the processes in the second system in sequence by executing the modified init process, writes the data into the disk, and closes the second system after the data are stored in sequence.
The execution order of step 206b and step 205b is not limited.
207b, the roots field closes the container corresponding to the second system after the preset time according to the second close command.
Illustratively, after the celld service in the Rootns domain receives the second close command sent by the kernel and waits for the set preset time, the celld service in the Rootns domain calls the instruction lxc-stop to close the container 2 in which the second system is located. Wherein waiting a preset time period ensures that the vessel 2 in which the second system is located is not closed until the second system is completely closed.
208. The kernel acquires an opening instruction, wherein the system opening instruction comprises an identifier of a system to be opened, and sends the opening instruction to a Roots domain.
For example, after step 207a or step 207b, if the closed system needs to be turned on again, an instruction to turn on the system may be sent to the kernel through a button "turn on another system" in the system that is not turned off, and after receiving the turn-on instruction, the kernel sends the turn-on instruction to the Rootns domain, where the turn-on instruction includes an identifier of the system to be turned on (where the identifier of the first system is vp1 and the identifier of the second system is vp 2).
209. The Rootns field calls an opening command, wherein the opening command is used for indicating to open a container corresponding to the identification of the system to be opened.
Illustratively, after step 208, the celld service in the Rootns domain will call the instruction lxc-start to open the container where the system to be opened is located.
In this embodiment, on the basis of the above embodiment, the kernel sends the obtained system shutdown instruction to the roots domain, where the instruction to shutdown the system includes the attribute value of the system identifier to be shutdown. After receiving the close command, the Rootns domain modifies the attribute value in the Rootns domain into the attribute value related to the system identifier to be closed, and sends the modified indication information of the attribute value of sys. The method comprises the steps that a first system and a second system monitor change information in a kernel through a poll mechanism in respective systems, after indication information which is sent by a Roots domain and carries an identification of a system to be closed is monitored, the indication information in the kernel is read through the poll mechanism, the first system and the second system respectively modify first preset attribute information and second preset attribute information according to the read indication information, and the modified first preset attribute information and second preset attribute information comprise the identification of the system to be closed. If the system matches that the identifier of the system to be closed is the identifier of the system, modifying the init process, executing the modified initi process, starting to sequentially stop processes in the system to store data, and simultaneously sending attribute information representing an instruction to be shut down to the kernel; after receiving the attribute information from the kernel, the Rootns domain sends a request for closing the container where the system to be closed is located to the kernel, and after receiving the instruction for closing the container, the Rootns domain calls lxc-stop to close the container where the system is closed after a preset time (i.e. after ensuring that the system is completely closed). And if the system is matched with the identifier of the system to be closed and is not the identifier of the system, continuing to operate the system. When a previously closed system needs to be opened, an open instruction may be obtained by the kernel and sent to the Rootns domain. And calling an opening command by the Rootns field to open the container where the system to be opened is positioned. By the method, the shutdown operation is performed on the systems in the dual systems, so that the processes in the systems to be shutdown are ensured to be sequentially closed, the abnormality of a disk is avoided, and a memory space is provided for the operation of the other system. Meanwhile, data can be written into the disk in sequence and stored, and the data can not be lost due to sudden shutdown. In addition, the hardware in the system can also sequentially release the memory on the kernel when the system is shut down, and the normal use of the hardware by the system which is not shut down can not be influenced. Moreover, after one system in the dual systems is closed, the container where the closed system is located is closed, so that the memory occupied by the container can be further released, more memory space is provided for the other system, and the system which is not closed is ensured to run more smoothly.
