Description

Message notification device and method for changing device configuration file

The present invention relates to a message notification system and method, and more particularly to a message notification apparatus and method for changing a device configuration file in a plurality of operating systems.

With the continuous development of computer technology, more and more computer systems (such as submersible systems) use multiple operating systems, such as Linux operating systems. However, under the existing multi-operation system architecture, each operating system needs to be configured with its own system resources. For example, the device configuration file needs to be stored in the storage unit corresponding to each operating system. In the case of a dual operating system, the same device configuration file not only needs to be stored in the storage unit of the first operating system, but also needs to be stored in the storage unit of the second operating system. This same file needs to be saved in two copies. The storage mechanism wastes storage space. In addition, when the device configuration file changes, the first operating system and the second operating system need to perform backup and change device configuration files in synchronization, which is cumbersome to operate, and occupies system resources, thereby reducing system execution efficiency.

In view of the above, it is necessary to provide a message notification device and method for changing a device configuration file, which enables multiple operating systems to share the same device configuration information and instantly monitor changes in shared device configuration information, thereby saving storage space and improving System efficiency.

The second operating system includes a message receiving module, configured to receive an event notification message sent by the message sending module, and notify the second application that the device configuration file has been changed according to the event notification message.

The message notification method for changing a device configuration file, the method comprising the steps of: initializing a first operating system and a second operating system, wherein the second operating system shares a device configuration file of the first operating system by using a network file system; Monitoring whether the device configuration file in the first operating system is changed; when the device configuration file is changed, generating an event notification message and notifying the event notification message that the device configuration file described by the first application of the first operating system has been changed Sending an event notification message to the second operating system; the second operating system receives the event notification message, and according to the event notification message, notifying that the device configuration file described by the second application of the second operating system has been changed.

Compared with the prior art, the message notification device and method for changing the device configuration file according to the present invention can enable multiple operating systems to share the same device configuration information, and monitor device configuration information in multiple operating systems in real time. A change occurs, and when the configuration file in a certain operating system changes, the message notification mechanism notifies each operating system to share the changed device configuration information.

As shown in FIG. 1, it is an implementation architecture diagram of a preferred embodiment of the message notification apparatus 100 for changing a device configuration file of the present invention. The message notification device 100 is installed with a plurality of operating systems, which are Windows operating systems or Linux operating systems. In the embodiment, the message notification device 100 includes a first operating system 1 and a second operating system 2. The first operating system 1 is executed by a first central processing unit (CPU) 15, which is executed by a second central processing unit 23. The first operating system 1 includes a first device management program 10, a device configuration file 11, a kernel monitoring module 12, a first application program 13, and a message sending module 14. The second operating system 2 includes a second device management program 20, a second application program 21, and a message receiving module 22.

The second operating system 2 shares the device configuration file 11 stored in the memory 16 by a network file system (NFS). The device configuration file 11 records configuration information of various devices, such as CPU configuration information, peripheral device configuration information, and I/O configuration information. The first device management program 10 or the second device management program 20 provides a user interface when the user changes the device information. When the user changes the device configuration information by using the first device management program 10 or the second device management program 20, the device configuration file 11 Record the corresponding device change information.

The kernel monitoring module 12 is configured to monitor the device configuration file 11 in the first operating system 1 in real time, and determine whether the device configuration file 11 is changed by the first device management program or the second device management program. When the device configuration file 11 is changed, the kernel monitoring module 12 generates an event notification message and notifies the event notification message that the device configuration file 11 described by the first application 13 has been changed, and sends the event notification message to the message. Module 14. After the first application 13 receives the event notification message, the kernel monitoring module 12 directly obtains the changed content of the device configuration file 11.

The message sending module 14 is configured to send the received event notification message to the second operating system 2. The message receiving module 22 is configured to receive an event notification message sent by the message sending module 14, and notify the second application 21 that the device configuration file 11 has been changed according to the event notification message. When the second application 21 receives the event notification message, the changed content of the device configuration file 11 in the first operating system 1 is shared by NFS.

As shown in FIG. 2, it is a flowchart of a preferred embodiment of a message notification method for changing a device configuration file according to the present invention. In this embodiment, the method can instantly monitor whether the device configuration information in the plurality of operating systems changes. When the configuration file in a certain operating system changes, the notification mechanism notifies each operating system to share the change. Device configuration information. This embodiment illustrates the present invention by taking only two operating systems as an example, namely the first operating system 1 and the second operating system 2 shown in FIG.

In step S21, the first central processing unit 15 initializes the first operating system 1, and the second central processing unit 23 initializes the second operating system 2. The second operating system 2 shares the device configuration file 11 in the first operating system 1 by a network file system (NFS). The device configuration file 11 records configuration information of various devices, such as CPU configuration information, peripheral device configuration information, and I/O configuration information. When the user changes the device configuration information by the first device management program 10 or the second device management program 20, the device configuration file 11 records the corresponding device change information.

In step S22, the kernel monitoring module 12 instantly monitors the device configuration file 11 in the first operating system 1. In step S23, the kernel monitoring module 12 checks whether the device configuration file 11 is changed by the first device management program 10. If the device configuration file 11 is not changed by the first device management program 10, step S24 is performed. If the device configuration file 11 has been changed by the first device management program 10, step S25 is performed.

In step S24, the kernel monitoring module 12 checks whether the device configuration file 11 is changed by the second device management program 20. If the device configuration file has not been changed by the second device management program 20, the process returns to step S22, that is, the kernel monitoring module 12 continues to monitor whether the device configuration file 11 in the first operating system 1 has been changed. If the device configuration file has been changed by the second device management program 20, step S25 is performed.

In step S25, the kernel monitoring module 12 generates an event notification message and notifies the event notification message that the device configuration file 11 described by the first application 13 has been changed. After the first application 13 receives the event notification message, the kernel monitoring module 12 directly obtains the changed content of the device configuration file 11.

In step S26, the kernel monitoring module 12 sends the event notification message to the message sending module 14, and the message sending module 14 sends the received event notification message to the second operating system 2.

In step S27, the message receiving module 22 of the second operating system 2 receives the event notification message sent by the message sending module 14, and informs the second application 21 that the device configuration file 11 has been changed according to the event notification message. After the second application 21 receives the event notification message, the change content of the device configuration file 11 in the first operating system 1 is shared by the network file system (NFS).
