Description

TECHNICAL FIELD

[0001] The present application relates to the field of operating systems, in particular to a method for starting a Linux operating system under a VOI architecture and a terminal. BACKGROUND

[0002] In the existing cloud computer project, the client is implemented by using the IPXE technology in combination with iSCSI to start the network boot system, and the same is true for the Galaxy Kirin desktop operating system. The Galaxy Kirin desktop operating system is a domestic Linux operating system, which has good software and hardware compatibility and supports domestic CPUs such as Feiteng, Kunpeng, Hisilicon Kirin, Longxin, Shenwei, Haiguang and Zhaoxin and platforms such as Intel and AMD. For the cloud computer Linux version client, the current program function only supports the Legacy (traditional BIOS) mode to start the Galaxy Kirin desktop operating system. On the one hand, this is affected by market demand, and on the other hand, the program version is developed earlier and is not further maintained subsequently.

[0003] In the prior art, the Legacy (traditional BIOS) mode uses the Int13 interrupt to read the disk, and only 64 KB can be read each time, which is very inefficient. The entire startup process is relatively long, resulting in a long boot time. With the development of technology, many new computer terminals support the UEFI startup mode. Even some computers have abandoned the Legacy (traditional BIOS) mode and only support the UEFI mode, or due to hardware reasons, such as the motherboard not supporting the read and write of underlying instructions, the terminal does not support the Legacy (traditional BIOS) mode. Therefore, the terminal that only supports the Legacy (traditional BIOS) mode startup has certain competitive disadvantages. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a method for starting a Linux operating system under a VOI architecture and a terminal, which solves the problem that some terminal devices cannot be started in the traditional startup mode due to hardware reasons.

[0005] To solve the above technical problems, a technical solution adopted by the present application is as follows:

[0006] A method for starting a Linux operating system under a VOI architecture, applied to a terminal, comprising the following steps:

[0007] S1, after booting, selecting to use the UEFI startup mode, using iPXE to download a startup boot file, and writing startup configuration information into a disk;

[0008] S2, using iPXE to obtain a list of operating system image files of a service end, selecting a system image from the list of operating system image files, obtaining and parsing an iSCSI disk path corresponding to the system image, and starting the system;

[0009] S3, loading a UEFI starter and a Linux kernel program, initializing the system, and completing starting of the Linux operating system under the VOI architecture.

[0010] To solve the above technical problems, another technical solution adopted by the present application is:

[0011] A terminal for starting a Linux operating system under a VOI architecture, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor implements each step in the method for starting the Linux operating system under the VOI architecture when executing the computer program.

[0012] The present application has the advantages of providing a method and a terminal for starting a Linux operating system under a VOI architecture, replacing a traditional BIOS mode, using a UEFI starting mode to start the Linux operating system, overcoming the problem that some terminal devices cannot use a Legacy (traditional BIOS) mode to start due to hardware reasons, simplifying the starting process, shortening the boot time, and bringing a better boot experience effect. Meanwhile, a UEFI system image file production method with strong portability is used, which provides technical reference experience for other Linux version operating systems supporting the UEFI starting mode.

[0065] Embodiment one

[0066] Please refer to Figures 1 to 3 The embodiment provides a VOI architecture Linux operating system startup method, which is particularly suitable for the Galaxy Kirin operating system and applied to a terminal, and includes the following steps:

[0067] S1, after booting, select to use the UEFI startup mode, download the startup boot file using iPXE, and write the startup configuration information into the disk.

[0068] Before step S1, the terminal also includes the following steps: making a Galaxy Kirin desktop operating system mirror supporting the UEFI mode startup, and uploading to a server, specifically:

[0069] Extracting the image information in the UEFI boot mode, and connecting with the iSCSI server;

[0070] Receiving the iSCSI disk returned by the server, and creating a disk partition and initializing a file system according to the information of the iSCSI disk;

[0071] Mounting the related partition of UEFI, copying the local image data into the iSCSI disk, regenerating the system parameters corresponding to UEFI, and completing the uploading of the image.

[0072] For the image making part, the embodiment provides a UEFI system image file making method with strong portability under a Linux operating system, which is not only suitable for the Galaxy Kirin desktop operating system involved in the embodiment, but also can realize corresponding functions by slightly modifying other Linux operating systems such as cenos and ubuntu.

[0073] The strong portability is specifically reflected in the image making shell script. The script is generally applicable to the system in the UEFI mode. Only the data copy command parameters may be different in different Linux operating systems. Therefore, when the shell script is transplanted to other Linux operating systems, only the data copy command in the shell script needs to be modified in the image making. Figure 4 That is, copying the local image data to the server iSCSI disk.

[0074] The whole system image making is completed by the shell script program in cooperation with the Linux version client, and an interface operation is provided for the user. Figures 5 to 7 The shell script program is responsible for the making of the image content, and the Linux version client is responsible for the display of the interface operation.

[0075] For the boot configuration information reading part, in the Legacy (traditional BIOS) boot mode, the iPXE writes the boot configuration information into the disk, and the Linux version client reads the boot configuration information through / dev / mem. However, for the UEFI mode, this method is not feasible, and therefore the embodiment provides a method for reading the boot configuration information in the UEFI mode of the Linux operating system, which is applicable to the UEFI mode of the Linux operating system. Figure 8 That is, the method is combined with the calling of the acpi system interface through ioctl. This method can be directly reused for other Linux operating systems such as cenos and ubuntu. The whole boot configuration information reading process is initiated by the upper application program, the ioctl device-level system call is used, and then the related acpi reading interface is called by the bottom driver to complete the reading and returning of the data.

[0076] S2, using iPXE, obtaining a list of operating system image files of a service end, selecting a system image from the list of operating system image files, obtaining and parsing an iSCSI disk path corresponding to the system image, and starting the system.

[0077] S3, loading a UEFI starter grubx64.efi and a Linux kernel program, displaying a boot list boot menu, initializing the system, and completing the starting of the Linux operating system under the VOI architecture.

[0078] Before step S3, the method further comprises obtaining the boot configuration information written into the disk by iPXE, and specifically comprises:

[0079] The VOI application program initiates an ioctl call, calls a corresponding acpi reading interface from the bottom layer driver program, and uses the acpi reading interface to return the boot configuration information.

[0080] Embodiment two

[0082] In summary, the method and the terminal for starting a Linux operating system under a VOI architecture provided by the application adopt a UEFI boot mode to start a Galaxy Kirin desktop operating system, and the starting process is completed by cooperation of iPXE, iSCSI, a service end, and a Kirin system image, so as to replace a traditional BIOS boot mode and solve the problem that some terminal devices cannot be started by the traditional boot mode due to hardware reasons.
