After the controlled machine and the control end establish a connection, the control end receives the desktop information sent by the server based on the client, and then performs remote desktop control on the controlled machine based on the desktop information.

[0003] However, since the server runs on the controlled machine, the server will occupy the resources of the controlled machine, such as CPU resources, network resources, etc., thereby affecting the business performance of the controlled machine. Summary of the Invention

It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0033] Generally, current remote desktop control technologies require deploying a server-side program, i.e., server, on the controlled machine and a client-side program, i.e., client, on the control end to achieve remote desktop control of the controlled machine by the control end. However, since the server runs on the controlled machine, the server will occupy the resources of the controlled machine such as CPU resources, network resources, etc., thereby affecting the business performance of the controlled machine. To address this problem, the embodiments of this disclosure provide a remote desktop control method based on DPU, which will be introduced below in conjunction with specific embodiments.

[0034] Figure 1 is a flowchart of a remote desktop control method based on DPU provided by the embodiments of this disclosure. This method can be executed by a remote desktop control device based on DPU. The remote desktop control device based on DPU can be implemented in software and / or hardware, and can be configured in an electronic device, such as a server or a terminal. Among them, the terminal specifically includes a mobile phone, a computer or a tablet computer, etc. In addition, this method can be applied to Figure 2 the application scenario shown in the figure. This application scenario includes a control end 10, a controlled unit 20 and a DPU 30 (i.e., Data Processing Unit, data processor). It can be understood that the remote desktop control method based on DPU provided by the embodiments of this disclosure can also be applied to other scenarios.

[0035] Such as Figure 2As shown, in the prior art, the control end 10 includes a remote control client program, namely client, and a first network interface card (Network Interface Card, NIC) for network communication. The controlled end 20 includes a remote control server program, namely server, and a second network interface card for network communication. That is to say, the remote control server program is deployed and runs in the controlled end 20.

[0036] In the present invention, the control end 10 still includes a remote control client program, namely client, and a first network interface card for network communication. However, the remote control server program in the controlled end 20 is sunk to the DPU 30 side. And a target graphics adapter component is deployed on the DPU 30 side, and a target graphics adapter driver corresponding to the target graphics adapter component is deployed on the controlled end 20 side to interact with the DPU 30. The control end 10 and the DPU 30 interact through the network. The DPU 30 exposes the target graphics adapter component to the controlled end 20 through an interface (VF or PF) to interact with the controlled end 20. Thereby, the service performance of the controlled end 20 is improved.

[0037] Next, in combination with Figure 2 the application scenario shown, Figure 1 the DPU-based remote desktop control method shown will be introduced. For example, Figure 2 the DPU 30 in

[0038] can execute this method. Figure 1 As shown, the DPU-based remote desktop control method provided in this embodiment is applied to the DPU, and a remote control server program and a target graphics adapter component are deployed in the DPU. Specifically, the DPU-based remote desktop control method includes the following steps.

[0039] S110. In response to a pending request sent by the control end, obtain a target descriptor corresponding to the pending request from a preset queue based on the target graphics adapter component, where the target descriptor is the descriptor corresponding to the most recent desktop image information of the controlled end.

[0040] In the embodiments of the present disclosure, the pending request may be a login request, a connection request, a control instruction, etc. sent by the control end.

[0041] The remote control server program is responsible for receiving requests or instructions sent by the control end and executing the received requests or instructions.

[0042] The target graphics adapter component may be a graphics adapter component based on para-virtualization technology and has certain virtualization standard specifications. Exemplarily, the target graphics adapter component may be a VirtIO-GPU component.

[0043] The preset queue can be a queue that is pre - set for storing descriptors corresponding to desktop image information.

[0044] Among them, the preset queue contains at least one descriptor, and at least one descriptor is generated by the target graphics adapter driver in the controlled end based on the desktop image information of the controlled end.

[0045] When the target graphics adapter component is a VirtIO - GPU component, the target graphics adapter driver is a VirtIO - GPU driver.

[0046] In the embodiments of the present disclosure, when there is an image to be displayed in the window system on the controlled end, the target graphics adapter driver is called based on a preset interface. The target graphics adapter driver obtains the desktop image information of the controlled end, converts the desktop image information into corresponding descriptors based on a preset protocol standard, and writes them into the preset queue pointed to by the preset register, so as to notify the target graphics adapter component located on the DPU.

[0047] The descriptor is used to describe the metadata of the desktop image information. Specifically, it can include information such as the storage address corresponding to the desktop image information, the size or character length of the desktop image information, etc.

[0048] Further, when the target graphics adapter component in the DPU responds to a pending request sent by the control end, it obtains the target descriptor corresponding to the pending request from the preset queue, that is, the descriptor corresponding to the desktop image information notified by the target graphics adapter driver most recently.

[0049] S120. Obtain the desktop image information based on the target graphics adapter component and the target descriptor.

[0050] In the embodiments of the present disclosure, the desktop image information may include desktop display contents such as open windows, application program interfaces, etc., and may also include information such as the resolution and color settings of the desktop screen, etc., which are not limited herein.

[0051] Specifically, after the DPU obtains the target descriptor, it parses the target descriptor based on the target graphics adapter, determines the target storage address corresponding to the target descriptor, reads the desktop image information from the target storage address, and thus obtains the desktop image information corresponding to the pending request.

[0052] S130. Send the desktop image information to the control end based on the remote control server program, so that the control end can perform remote desktop control on the controlled end based on the desktop image information.

[0053] Specifically, after obtaining the desktop image information, the DPU sends the desktop image information to the control end based on the remote control server program, so that after receiving the desktop image information, the control end performs remote desktop control on the controlled end based on the desktop image information.

[0054] In the embodiment of the present disclosure, in response to a processing request sent by the control end, a target descriptor corresponding to the processing request is obtained from a preset queue based on the target graphics adapter component. The target descriptor is the descriptor corresponding to the most recent desktop image information of the controlled end. Then, based on the target graphics adapter component and the target descriptor, the desktop image information is obtained. After obtaining the desktop image information, the desktop image information is sent to the control end based on the remote control server program, so that the control end performs remote desktop control on the controlled end based on the desktop image information. Thus, by sinking the remote control server program from the host side of the controlled end to the DPU, the problem that the remote control server program runs on the controlled end and occupies the resources of the controlled end is avoided, and further the service performance of the controlled end is improved.

[0055] Based on the above embodiments of the present disclosure, by deploying the target graphics adapter component in the DPU to communicate with the controlled end, physical isolation is achieved between the user of the control end and the controlled end. And at least one access interface is deployed on the target graphics adapter component, and each access interface corresponds to a target user. The target user is the user who performs remote desktop control on the controlled end through the control end. Each target user corresponds to target resources in the target graphics adapter component. Thus, each target user can only access the target graphics adapter component and access its corresponding target resources through its corresponding access interface, improving access security and avoiding data leakage between multiple users.

[0056] Among them, the access interface can be in the form of an interface based on PF (Physical Function) or VF (Virtual Function).

[0057] In the embodiment of the present disclosure, after obtaining the desktop image information based on the target graphics adapter component and the target descriptor, the remote desktop control method based on the DPU may further include: performing format conversion processing on the desktop image information based on the target graphics adapter component to obtain the desktop image information in the target format.

[0058] Among them, the format conversion processing can be understood as performing processing such as compression encoding on the desktop image information based on a preset remote desktop protocol and converting it into a format that the remote control server program can recognize.

[0059] Specifically, after acquiring the desktop image information, the DPU performs format conversion processing on the desktop image information based on the target image adapter component to obtain the desktop image information in a target format that can be recognized by the remote control server program.

[0060] Furthermore, sending the desktop image information to the control end based on the remote control server program may specifically include: sending the desktop image information in a target format to the control end based on the remote control server program.

[0061] In an embodiment of the present disclosure, after obtaining desktop image information based on the target graphics adapter component and the target descriptor, the DPU-based remote desktop control method may also include: sending a notification message to the target graphics adapter driver in the controlled end based on the target graphics adapter component, the notification message being used to inform the target graphics adapter driver of the processing result of the desktop image information corresponding to the target descriptor.

[0062] The notification message includes the processing status of the desktop image information.

[0063] Specifically, after the DPU obtains the desktop image information based on the target graphics adapter component, it sends the desktop image information to the remote control server program based on the target graphics adapter component, and sends a notification message to the target adapter driver to inform the graphics adapter driver of the processing result of the desktop image information corresponding to the descriptor, that is, whether the pending request has been processed. Furthermore, the DPU injects an interrupt event to the controlled end, and the interrupt handler will feed back the completion status of the pending request to the window system. In this way, the completion status of the pending request can be fed back to the controlled end in a timely manner.

[0064] Figure 3 is a flow chart of another DPU-based remote desktop control method provided by an embodiment of the present disclosure, such as Figure 3 As shown, the DPU-based remote desktop control method may include the following steps:

[0065] S310: Receive a request to be processed sent by the control end based on the remote control server program.

[0066] S320, in response to the pending request sent by the control terminal, based on the target graphics adapter component, obtain a target descriptor corresponding to the pending request from a preset queue, where the target descriptor is a descriptor corresponding to the most recent desktop image information of the controlled terminal.

[0067] S330: Acquire desktop image information based on the target graphics adapter component and the target descriptor.

[0068] S340. Perform format conversion processing on the desktop image information based on the target graphics adapter component to obtain the desktop image information in the target format.

[0069] S350. Send the desktop image information in the target format to the control end based on the remote control server program, so that the control end performs remote desktop control on the controlled end based on the desktop image information in the target format.

[0070] S360. Send a notification message to the target graphics adapter driver in the controlled end based on the target graphics adapter component. The notification message is used to inform the target graphics adapter driver of the processing result of the desktop image information corresponding to the target descriptor.

[0071] It should be noted that the execution order of step S350 and step S360 is not restricted. Step S350 and step S360 can be executed simultaneously. Step S350 can be executed before step S360, and step S350 can also be executed after step S360. There is no restriction here.

[0072] In the embodiment of the present disclosure, communication can be carried out between the remote control server program and the control end, and communication can be carried out between the target graphics adapter component and the controlled end, realizing the transmission of the desktop image information of the window system of the controlled end to the control end. By sinking the remote control server program from the host side of the controlled end to the DPU, the problem that the remote control server program runs on the controlled end and occupies the resources of the controlled end can be avoided, thereby improving the service performance of the controlled end.

[0073] In the embodiment of the present disclosure, after the desktop image information is sent to the control end, the control end will perform remote desktop control on the controlled end based on the desktop image information, which further involves the processing of the control data of the control end, that is, the process of sending the control data of the control end to the controlled end.

[0074] Figure 4 It is a flowchart of a control data processing method provided by the embodiment of the present disclosure. As Figure 4 shown, the control data processing method may specifically include the following steps:

[0075] S410. Receive the control data sent by the control end based on the remote control server program, and construct a target instruction based on the control data. The control data includes keyboard data and / or mouse data.

[0076] In the embodiment of the present disclosure, the control data is the data captured by the remote control client program in the control end for controlling the controlled end.

[0077] The keyboard data may include key information, key status, input content, etc. of the keyboard; the mouse data may include position information, movement trajectory, click information, etc. of the mouse.

[0078] The target instruction can be understood as an instruction for transmitting and storing control data. This target instruction depends on the driver of the PCIe device. The target instruction may include the storage location information of the control data and the register information. The register information includes the information of the data register for storing the control data, and also includes the control register information for storing the storage location information of the control data.

[0079] Specifically, after the DPU sends the desktop image information to the control end, it can receive the control data sent by the control end in real time based on the remote control server program. After receiving the control data, the remote control server program constructs a target instruction according to the control data and the preset transmission mechanism.

[0080] Further, after constructing the target instruction, the remote desktop control method based on the DPU may further include: sending an interrupt event to the controlled end, so that after receiving the interrupt event, the controlled end performs an interrupt operation corresponding to the interrupt event.

[0081] S420: Send the target instruction to the controlled end, so that the controlled end obtains the control data based on the graphics adapter driver and the target instruction, and performs corresponding operations based on the control data.

[0082] Specifically, the DPU sends the target instruction to the controlled end and injects an interrupt event into the controlled end. The controlled end parses the target instruction based on the interrupt handler and obtains the control data from the data register and places it in the memory. In the soft interrupt, the control data is injected into the operating system of the controlled end to perform corresponding operations.

[0083] In the embodiments of the present disclosure, it is possible to receive the control data sent by the control end through the remote control server program and construct a target instruction to transmit the control data to the controlled end, that is, a transmission channel for transmitting the control data to the controlled end is established, realizing the transmission of the control data to the controlled end, and further enabling the controlled end to perform corresponding operations based on the control data.

[0088] The second acquisition module 520 can be configured to acquire desktop image information based on the target graphics adapter component and the target descriptor.

After acquiring the desktop image information, the desktop image information is sent to the control end based on the remote control server program, so that the control end performs remote desktop control on the controlled end based on the desktop image information.
