[0005] However, there are technical challenges in porting Android applications to embedded Linux systems, mainly due to the architectural differences and resource allocation issues between the two. Summary of the invention

[0006] In view of this, one or more embodiments of the present disclosure provide a method, apparatus and computer device that are compatible with running dual operating systems, which can run two different operating systems at the same time, making it convenient for users to use application programs of different operating systems.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0030] In the related technology, a method for running Android applications on an embedded Linux operating system may include the following steps: installing necessary dependencies for the Android environment; providing an Android operating environment using a container (Docker); installing Android applications in the Android operating environment; configuring various hardware and software resources; customizing the user interface and interaction method of the Android application; and realizing operation control of the Android application.

[0031] However, in the related art, the resource occupancy rate of the Android system running in the container is relatively fixed. If the usage resources of the Android system need to be changed, manual adjustment is often required, resulting in cumbersome steps and low adjustment efficiency.

[0032] In view of this, the method for compatible running of dual operating systems provided by the present invention can not only run two different operating systems on the same device at the same time, making it convenient for users to use applications of different operating systems, but also effectively manage memory resources and support dynamic adjustment of memory resources allocated to the second operating system.

[0033] See also Figure 1 , a method for running dual operating systems compatibly provided by an embodiment of the present disclosure may include the following steps.

[0034] S1: According to the target file system, a first operating system is installed, where the first operating system is built based on a first Linux kernel.

[0035] In this implementation, the target file system includes a root directory file system, a user file system and an extended file system of an extended device; the root directory file system is used to provide startup resources for the first operating system, and the user file system is used to store user files.

[0036] Specifically, the root directory file system is all the files and directories under the root directory, which may include the kernel of the operating system, system libraries, command line tools, system configuration files, and user space applications, etc. The user file system includes the data stored by the user, such as various documents, audio, video, software products, etc. Expansion devices may include external hard disks, USB flash drives, optical disks, etc.

[0037] The first operating system and the second operating system can call the target file system, and the target file system includes not only the root file system necessary for starting the first operating system, but also the user file system for storing user files and the extended file system for extended devices. In this way, the scenario adaptability of the method is improved and can meet more application scenarios.

[0038] S2: Install a desktop system and a virtual machine startup program on the first operating system.

[0039] In this embodiment, after the first operating system is installed, the computing environment and resource configuration suitable for the second operating system can be simulated through virtual machine technology, so that the second operating system and the application programs in the second operating system can be installed and run in the same device. The installation of the desktop system is conducive to more convenient control and display of the first operating system.

[0040] S3: Start the target virtual machine and the resource allocation unit through the virtual machine startup program, and the resource allocation unit is used to manage the memory resources of the target file system.

[0041] In this embodiment, the memory resources of the target file system can be managed and allocated through the resource allocation unit to optimize the memory resource utilization. The resource allocation unit can manage the memory resources of the method implementation subject (such as a computer, a mobile smart device, an embedded device) that carries the target file system, including physical memory and virtual memory. The resource allocation unit can allocate, recycle and control access to memory resources. In some actual application scenarios, the resource allocation unit can also use more memory space than the actual physical memory through virtual memory technology.

[0042] S4: Using the target virtual machine, install a second operating system, where the second operating system is built based on a second Linux kernel, and the second operating system has permission to call the target file system.

[0043] In this embodiment, the first operating system and the second operating system are built based on the first Linux kernel and the second Linux kernel respectively, which not only ensures that both operating systems can call the target file system and realize necessary resource sharing and communication, but also can realize resource isolation to a certain extent, reduce mutual interference between the two operating systems, and improve the stability and security of the two operating systems.

[0044] The method for compatible running of dual operating systems provided in this embodiment may also include step S5: changing the memory resources allocated by the target file system to the target virtual machine according to the resource utilization rate of the target file system by the first operating system and the resource utilization rate of the target file system by the second operating system.

[0045] In this embodiment, the memory resources allocated by the target file system to the target virtual machine can be dynamically adjusted according to the resource utilization of the first operating system and the second operating system, thereby further optimizing resource utilization efficiency and avoiding resource waste.

[0046] In some implementations, the memory resources allocated by the target file system to the target virtual machine may be changed based on a first call ratio of the first operating system to the target file system, a memory fragmentation rate of the first operating system, a second call ratio of the second operating system to the target file system, and a cache hit rate of the second operating system.

[0047] The indicator data of the four dimensions are optimized to accurately reflect the resource utilization of the first operating system and the second operating system, and to more efficiently adjust the memory resources allocated to the target virtual machine by the target file system.

[0048] In some embodiments, the change probability coefficient may be determined based on a first call ratio of the first operating system to the target file system, a memory fragmentation rate of the first operating system, a second call ratio of the second operating system to the target file system, and a cache hit rate of the second operating system. When the change probability coefficient is greater than or equal to a preset increase coefficient, the memory resources allocated by the target file system to the target virtual machine may be increased. When the change probability coefficient is less than a preset decrease coefficient, the memory resources allocated by the target file system to the target virtual machine may be reduced.

[0049] By changing the probability coefficient, the conditions and plans for adjusting memory resources can be clarified, thereby improving the efficiency of dynamic adjustment of memory resources.

[0050] In some implementations, the change probability coefficient is determined according to the first call ratio of the first operating system to the target file system, the memory fragmentation rate of the first operating system, the second call ratio of the second operating system to the target file system, and the cache hit rate of the second operating system, which can be implemented by the following formula:

[0051]

[0052] In the formula, G represents the change probability coefficient, m1 represents the first call ratio of the first operating system to the target file system, m2 represents the second call ratio of the second operating system to the target file system, a represents the memory fragmentation rate of the first operating system, and c represents the cache hit rate of the second operating system.

[0053] In an actual application example, when G≥72%, it indicates that the resource occupation ratio of the target virtual machine or the second operating system needs to be increased. At this time, the memory resources allocated to the target virtual machine by the target file system can be increased through the resource allocation unit under certain restrictions (for example, the memory resource ratio increased each time does not exceed 20% of the currently allocated memory resources).

[0054] When G<32%, it indicates that the resource usage ratio of the target virtual machine or the second operating system needs to be reduced. At this time, the memory resources allocated to the target virtual machine by the target file system can be reduced through the resource allocation unit under certain restrictions (for example, the memory resource ratio reduced each time does not exceed 20% of the currently allocated memory resources).

[0055] See also Figure 2 , a method for running dual operating systems compatibly provided by an embodiment of the present disclosure may include the following steps.

[0056] Step 1: Install the Linux system based on Linux kernel 1 according to the file system; the file system includes all files and directories under the root directory, and other file systems and devices are connected to the main file system through mount points. Other file systems mainly include data stored by the user, and devices include hard disks, USB flash drives, and optical disks.

[0057] Step 2: Install the desktop system and virtual machine startup program on the Linux system.

[0058] Step 3: Start the VirtualBox virtual machine and resource allocation unit through the virtual machine startup program; the resource allocation unit is responsible for managing the computer's memory resources, including the allocation, recycling and access control of physical memory and virtual memory. The resource allocation unit can also use virtual memory technology to allow programs to use more memory space than actual physical memory.

[0059] Step 4: The VirtualBox virtual machine installs the Android-x86 image based on Linux kernel 2 as the boot disk, and after starting the virtual machine, the Android system can also call the file system resources;

[0060] Step 5: The resource allocation unit allocates resource usage ratios of the Linux system and the VirtualBox virtual machine according to the utilization rate of the file system by Linux kernel 1 and the utilization rate of the file system by Linux kernel 2.

[0061] In this embodiment, whether to increase or decrease the resource occupancy ratio of Linux kernel 2 is determined by the call ratio of Linux kernel 1 to the file system and the memory fragmentation rate, and the call ratio of Linux kernel 2 to the file system and the cache hit rate. This judgment method is not only more efficient, but also greatly reduces the resource allocation unit's own occupancy rate of resources.

[0062] In an actual application example, the resource allocation unit can determine whether to increase or decrease the resource usage ratio of Linux kernel 2 based on the call ratio and memory fragmentation rate of the file system in Linux kernel 1, and the call ratio and cache hit rate of Linux kernel 2 to the file system. Then:

[0063]

[0064] Where G represents the probability coefficient of increasing or decreasing the resource usage of Linux kernel 2, m1 represents the call ratio of the file system in Linux kernel 1, m2 represents the call ratio of the file system in Linux kernel 2, a represents the memory fragmentation rate of Linux kernel 1, and c represents the cache hit rate of Linux kernel 2.

[0065] When G ≥ 72%, it means that the resource usage ratio of Linux kernel 2 needs to be increased, and the resource usage ratio increased each time shall not exceed 20%;

[0066] When G<32%, it means that the resource usage ratio of Linux kernel 2 needs to be reduced, and the resource usage ratio reduced each time shall not exceed 20%.

[0067] Then, when the call ratio of the file system in Linux kernel 1 is m1=41%, the call ratio of the file system in Linux kernel 2 is m2=26%. In addition, the memory fragmentation rate of Linux kernel 1 is a=11%, and the cache hit rate of Linux kernel 2 is c=18%, then:

[0068]

[0069] From the above calculation, it can be known that the resource allocation needs to increase the resource usage ratio of Linux kernel 2, and the resource ratio increased each time does not exceed 20%.

[0070] The technical solution provided by one or more embodiments of the present disclosure can simulate the computing environment and resource configuration suitable for the second operating system through virtual machine technology on the basis of installing the first operating system, so that the second operating system and the application program in the second operating system can be installed and run in the same device. The first operating system and the second operating system are respectively constructed based on the first Linux kernel and the second Linux kernel, which not only ensures that both operating systems can call the target file system and realize the necessary resource sharing and communication, but also can realize resource isolation to a certain extent, reduce the mutual interference between the two operating systems, and improve the stability and security of the two operating systems. Through the resource allocation unit, the memory resources of the target file system can also be managed and allocated to optimize the utilization of memory resources.

[0079] In one embodiment, the resource allocation unit 500 is specifically used to determine the change probability coefficient based on the first call ratio, the memory fragmentation rate, the second call ratio, and the cache hit rate; when the change probability coefficient is greater than or equal to a preset increase coefficient, the memory resources allocated by the target file system to the target virtual machine are increased; when the change probability coefficient is less than a preset reduction coefficient, the memory resources allocated by the target file system to the target virtual machine are reduced.
