[0053] The present application provides a method, device, DPU and server for adapting a DPU to multiple operating systems. By running a target image file in a local operating system and entering the target image operating system, the DPU can be adapted to multiple versions of operating systems without specifying a local operating system pre-installed on the DPU, thereby enabling the DPU to meet different usage requirements.

[0054] The method for adapting a DPU to multiple operating systems provided by the present application will be described in detail below with reference to the accompanying drawings.

[0055] The present application provides a first method for adapting a DPU to multiple operating systems, which is applied to a DPU.

[0056] See also Figure 1 , Figure 1 1 is a flow chart of a first implementation of a first method for adapting a DPU to multiple operating systems provided in an embodiment of the present application. Figure 1 As shown, the first method for adapting a DPU to multiple operating systems includes: steps S100 to S200.

[0057] Step S100: receiving an execution instruction, and obtaining a target image file from an image resource module according to the execution instruction.

[0058] The image resource module includes multiple image files, and the target image file is one of the multiple image files.

[0059] In some implementations, the mirror resource module is stored in a mirror resource server connected to the DPU.

[0060] Optionally, the DPU is connected to an image resource server via a network to obtain a target image file from the image resource module.

[0061] In some embodiments, the DPU includes a local operating system.

[0062] In some implementations, the execution instruction includes specified information of the target image file.

[0063] In some implementations, the local operating system of the DPU is used to receive an execution instruction, select an image file as the target image file from multiple image files in the image resource module according to the specified information of the target image file in the execution instruction, and download the target image file.

[0064] Optionally, the specified information of the target image file is an identifier or a storage address of the target image file.

[0065] In some implementations, the local operating system of the DPU includes a container engine, which is used to obtain and run an image file in the image resource module.

[0066] An image file is a lightweight, independent, executable software package that contains all the code, libraries, environment variables, and configuration files needed to run the operating system.

[0067] Optionally, the container engine is also used to manage multiple image files in the image resource module.

[0068] Optionally, the container engine may be a Docker container engine.

[0069] In some implementations, the container engine receives the execution instruction and obtains the target image file from the image resource module.

[0070] In some implementations, running the target image file may enter the target image operating system in the local operating system of the DPU, where the target image operating system is an operating system specified by a user to be used on the DPU.

[0071] Step S200: Run the target image file in the local operating system to enter the target image operating system.

[0072] In some implementations, the container engine runs the target image file in the local operating system and enters the target image operating system.

[0073] Optionally, the target image operating system is a container generated by the container engine running the target image file. A container is a running instance of an image file. A container is an isolated, lightweight running environment.

[0074] By running the target image file in the local operating system and entering the target image operating system, the DPU can be adapted to multiple versions of operating systems without specifying the local operating system pre-installed on the DPU, thereby enabling the DPU to meet different usage requirements.

[0075] See also Figure 2 , Figure 2 1 is a flow chart of a second implementation of the first method for adapting a DPU to multiple operating systems provided in an embodiment of the present application. Figure 2 As shown, in some implementations, the first method for adapting the DPU to multiple operating systems includes: steps S100 to S300.

[0076] Step S100: receiving an execution instruction, and obtaining a target image file from an image resource module according to the execution instruction.

[0077] Step S200: Run the target image file in the local operating system to enter the target image operating system.

[0078] The contents of step S100 to step S200 refer to the above description.

[0079] Step S300: receiving an operation instruction, and running the target DPU service software in the target image operating system according to the operation instruction.

[0080] In some implementations, the target mirror operating system includes a plurality of DPU service software, and the DPU service software is used to extend the functionality of the mirror operating system.

[0081] In some embodiments, the DPU service software includes OVS (Open vSwitch, open virtual switch) software, DPDK (Data Plane Development Kit) software, RDMA (Remote Direct Memory Access, remote direct memory access) software and PCI (Peripheral Component Interconnect, peripheral component interconnect) device simulation software, etc.

[0082] In some embodiments, OVS software is used to implement network bridging functions in a network virtualization environment. DPDK software is used to improve the performance and efficiency of network packet processing. RDMA software is used to implement remote direct memory access. PCI device simulation software is used to simulate PCI or PCIE (PCI Express) devices so that the host server connected to the DPU can identify and use the resources of the simulated PCI or PCIE devices.

[0083] In some implementations, the target DPU service software is a target DPU service software among the multiple DPU service softwares, and the target DPU service software is also the DPU service software specified by the user to be used. In this way, the DPU can further meet different usage requirements.

[0084] The present application also provides a second method for adapting a DPU to multiple operating systems, which is applied to a server. The server is a mirror resource server connected to the DPU.

[0085] See also Figure 3 , Figure 3 1 is a flow chart of a first implementation of a second method for adapting a DPU to multiple operating systems provided in an embodiment of the present application. Figure 3 As shown, the second method for adapting the DPU to multiple operating systems includes: steps S400 to S600.

[0086] Step S400: Obtain the system kernel corresponding to each mirror operating system version.

[0087] In some implementations, the system kernel is a Linux operating system kernel. The Linux operating system is an open source and free operating system based on Unix. The Linux operating system usually has different versions, and the source code of the system kernel corresponding to each version is different.

[0088] In some implementations, there are multiple versions of the mirrored operating system.

[0089] In some embodiments, the mirror operating system versions include openEuler, Ubuntu, Dragon Lizard, BC-Linux, CentOS 8, and Kylin, etc.

[0090] In some implementations, the system kernel may also be the kernel of other operating systems, such as the kernel of a Windows operating system or a kernel of a BSD operating system.

[0091] Step S500: Obtain a patch file adapted to each system kernel.

[0092] Among them, the patch file is used to expand the functions of the mirror operating system.

[0093] In some implementations, the patch file is used to implement the target functionality of the DPU.

[0094] Exemplarily, the target function of the DPU includes a peripheral driver reporting function of the DPU.

[0095] In some implementations, there are multiple patch files adapted to one system kernel, and all patch files adapted to one system kernel need to be acquired.

[0096] In some embodiments, step S500 includes step (500.1) to step (500.2).

[0097] (500.1) Obtain a list of patch files corresponding to each image operating system version.

[0098] In some implementations, a patch file list includes identifiers of all patch files adapted to a system kernel corresponding to an image operating system version.

[0099] (500.2) Obtain a patch file adapted to each system kernel according to the patch file list.

[0100] In some implementations, for each system kernel, all patch files adapted to the system kernel are acquired according to a patch file list corresponding to the system kernel.

[0101] Optionally, all patch files are acquired according to identifiers of all patch files in the patch file list.

[0102] Optionally, the server has stored all patch files, the identifier of the patch file in the patch file list is the storage address of the patch file, and the server obtains the patch file according to the storage address of the patch file.

[0103] Optionally, the identifier of the patch file in the patch file list is the name or download address of the patch file, and the server downloads the patch file from the Internet according to the name or download address of the patch file.

[0104] Step S600: Compile each system kernel according to the patch file to obtain an initial image file corresponding to each image operating system version.

[0105] In some implementations, one image operating system version corresponds to one system kernel, and one system kernel corresponds to multiple patch files. Thus, multiple patch files corresponding to one image operating system version can be obtained.

[0106] In some implementations, a system kernel corresponding to an image operating system version is compiled according to all patch files corresponding to the image operating system version to obtain an initial image file corresponding to the image operating system version.

[0107] In some implementations, when the mirror operating system does not need to include the DPU service software, the initial mirror file is the mirror file included in the mirror resource module. After executing step S600, the server stores all initial mirror files in the mirror resource module.

[0108] See also Figure 4 , Figure 4 1 is a flow chart of a second implementation of a second method for adapting a DPU to multiple operating systems provided in an embodiment of the present application. Figure 4As shown, in some embodiments, the second method for adapting the DPU to multiple operating systems includes: steps S400 to S800.

[0109] Step S400: Obtain the system kernel corresponding to each mirror operating system version.

[0110] Step S500: Obtain a patch file adapted to each system kernel.

[0111] Step S600: Compile each system kernel according to the patch file to obtain an initial image file corresponding to each image operating system version.

[0112] Steps S400 to S600 refer to the above description.

[0113] Step S700: Obtain the installation file of the DPU service software adapted to each initial image file.

[0114] In some implementations, there are multiple DPU service software that are compatible with one initial image file, and it is necessary to obtain all DPU service software that are compatible with one initial image file.

[0115] In some embodiments, step S700 includes step (700.1) to step (700.2).

[0116] (700.1) Obtain a list of DPU service software files corresponding to each initial image file.

[0117] In some implementations, a DPU service software file list includes identifiers of installation files of all DPU service software that are compatible with a corresponding initial image file.

[0118] (700.2) Obtain the installation file of the DPU business software compatible with each initial image file according to the DPU business software file list.

[0119] In some implementations, for each initial image file, installation files of all DPU service software compatible with the initial image file are obtained according to a DPU service software file list corresponding to the initial image file.

[0120] Optionally, the installation files of all the DPU service software are acquired according to the identifiers of the installation files of all the DPU service software in the DPU service software list.

[0121] Optionally, the server has stored the installation files of all DPU business software, the identifier of the DPU business software is the storage address of the installation file of the DPU business software, and the server obtains the installation file of the DPU business software according to the storage address of the installation file of the DPU business software.

[0122] Optionally, the identifier of the DPU service software is the name or download address of the DPU service software, and the server downloads the installation file of the DPU service software from the Internet according to the name or download address of the DPU service software.

[0123] Step S800: Compile each initial image file according to the installation file of the DPU service software to obtain a final image file corresponding to each image operating system version.

[0124] In some implementations, an initial image file is compiled according to installation files of all DPU service software corresponding to the initial image file to obtain a final image file.

[0125] In some implementations, when the mirror operating system needs to include DPU service software, the final mirror file is the mirror file included in the mirror resource module. After executing step S800, the server stores all final mirror files in the mirror resource module.

[0126] In summary, the method for adapting a DPU to multiple operating systems provided in the embodiment of the present application includes the following advantages:

[0127] 1. By running the target image file in the local operating system and entering the target image operating system, the DPU can be adapted to multiple versions of operating systems without specifying the local operating system pre-installed on the DPU, so that the DPU can meet different usage requirements.
