Description
Technical Field
The invention relates to a cursor control method, in particular to a control method for displaying a BIOS setting interface cursor on an SOL page.
Background
BMC management software on the server motherboard provides SOL functionality for remotely modifying BIOS configurations. After the BIOS opens the serial port redirection function, the user can remotely configure the BIOS on the front-end webpage of the BMC by using the SOL function. The BIOS transmits the full image data and cursor data of the setting interface to the BMC only when the SOL connection is established for the first time. In other cases, only a small amount of VT100+ control code data with a changed portion is transmitted to the BMC as required based on the last data. The BMC needs to store image data and cursor position coordinates for use when the front end draws an image. When a user controls the cursor to move on the same page of the BIOS setting interface through the SOL function, only the position coordinates of the cursor and a small amount of partial image data are changed, so that the BIOS only transmits the changed part of the image data and the position data of the cursor to the BMC. At the moment, when the BIOS setting interface image is drawn on the front-end page of the BMC by using the single canvas, the pixel at the position of the cursor in the original image data stored by the BMC is damaged because the cursor image is attached to the original image. This results in a plurality of black non-pixel squares of the same size as the cursor appearing in the image ultimately presented to the customer, which can affect the judgment and experience of the user.

Detailed Description
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
During the period of using the SOL function, the key command of the user is forwarded to the BIOS by the BMC, and the BIOS also uses the VT100+ control code to continuously transmit the image data of the setting interface and the current cursor data to the BMC as required. The VT100 control code data transmitted by the BIOS to the BMC does not contain cursor image data, and only the position of a cursor on a BIOS interface or the control action of the cursor. The cursor position represents the current focus item of the BIOS setting interface, the BMC front end needs to combine the image data obtained from the BIOS with the cursor data, and finally the user-friendly BIOS setting interface actual image with the cursor is displayed on the webpage.
In the english abbreviation used in the present application, BMC denotes a substrate Management Controller, i.e., a Baseboard Management Controller, which is generally built in a motherboard and supports the IPMI specification of the industry standard; the functions provided by the BMC include: local and remote diagnostics, console support, configuration management, hardware management, and troubleshooting. The BIOS refers to a Basic Input Output System, that is, a Basic Input Output System, and is mainly used for initialization and detection of various hardware devices in a computer boot process. WebSocket refers to a protocol for full duplex communication over a single TCP connection. The VT100+ control code refers to a code for extending a display at a terminal. The RFC6455 specification refers to the WebSocket protocol specification. SOL represents the use of IPMI data packets to transmit Serial data Over the network, i.e., serial Over LAN, which is mainly used to redirect the Serial data to the front-end web page.
The method and the device aim at solving the problem that a plurality of black pixel-free squares can appear on the interface along with the movement of a user control cursor when the BMC front end shows the BIOS to set the interface image through SOL, and on the basis, the method and the device also aim at solving the problem of image damage caused by drawing of a single canvas. According to the method and the device, the hidden cache canvas is used, the original image data stored by the BMC and the final data used for displaying are drawn and processed separately, and the problem that the original image data is damaged due to drawing of a single canvas is avoided; after the optimized control process is carried out, in the image finally displayed to the user, no black non-pixel block is generated due to the movement of the cursor, so that the user experience of displaying the BIOS setting interface on the SOL page is greatly improved.
As shown in fig. 1 and fig. 2, the present embodiment provides a control method for displaying a BIOS setting interface cursor on an SOL page, including the following steps:
step S1, establishing WebSocket full duplex long connection between a BMC front-end webpage and a back-end SOL service through a network, and then establishing serial connection between the back-end SOL service and a BIOS;

s4, drawing an image on the hidden cache canvas, copying complete image data to a visible canvas for display, and jumping to the S6 after the completion;
s5, calculating the final position of the cursor according to the cursor data, and jumping to the S6 after the final position of the cursor is calculated;
s6, performing synthesis drawing and display on the visible canvas;
step S7, judging whether to quit the back-end SOL service, if so, ending; if not, jumping to the step S8;
and S8, converting the WebSocket network data into serial port data by the back-end SOL service, forwarding the serial port data to the BIOS through serial port connection, and returning to the step S2.

Then the back-end SOL service of the BMC establishes serial port connection with the BIOS, the BIOS continuously transmits image data and cursor data to the back-end SOL service of the BMC according to needs through the serial port, then the back-end SOL service of the BMC encodes according to RFC6455 specifications, and the encoded data is transmitted to a front-end webpage (front-end webpage for short) of the BMC through WebSocket connection. Meanwhile, the keyboard operation instruction of the user is also sent to the back-end SOL service of the BMC by the BMC front-end webpage through WebSocket connection, and is decoded according to RFC6455 specification and then forwarded to the BIOS through serial port connection. The back-end SOL service of the BMC is used as a transfer station and provides conversion and forwarding functions for data transmission between a BMC front-end webpage and a BIOS.
In step S2 of this embodiment, after receiving data forwarded by the back-end SOL service through the WebSocket full duplex long connection, the BMC front-end web page may analyze the received VT100 control code data according to the VT100 control code specification, where the forwarded data is the VT100 control code data from the BIOS.
In step S2 of this embodiment, after the connection is established in step S1, the BIOS continuously transmits the image data and the cursor data to the backend SOL service through the serial port, and then the backend SOL service encodes the image data and the cursor data according to RFC6455 specification and forwards the image data and the cursor data to the BMC front-end web page through the WebSocket full-duplex long connection; meanwhile, the received keyboard operation instruction is also sent to the back-end SOL service by the BMC front-end webpage through WebSocket full duplex long connection, and is decoded according to RFC6455 specification and then forwarded to the BIOS through serial port connection.

In step S4, in this embodiment, the BMC front-end webpage draws characters, character background colors, and blank area images of corresponding colors on a hidden cache canvas, and obtains original image data for display by combining with the VT100 control code specification; the complete original image data in the hidden cache canvas is then copied onto the visible canvas for presentation. By the aid of the design, the cache canvas can be well utilized to avoid damage of images, and further, the situations of black points, black non-pixel squares and the like in the prior art are avoided.
In this embodiment, in step S5, the BMC front-end webpage calculates a final position of the cursor by adding the cursor movement offset to the current coordinate of the cursor according to the cursor movement offset and by combining the current coordinate of the cursor, and draws a cursor image at a corresponding position on the visible canvas by using the final position of the cursor.
After the step S4 and the step S5 are completed, in the embodiment, in the step S6, the complete original image data obtained in the step S4 and the cursor image obtained in the step S5 are synthesized and drawn, and after completion, a complete BIOS setting interface image can be displayed on a front-end page for a user to check, so that display is realized.
As shown in fig. 2, the step S8 in this embodiment includes the following sub-steps:
step S801, controlling a BIOS setting interface through an SOL page;
step S802, the BMC front-end webpage sends VT100 control code data corresponding to the control operation through WebSocket;
step S803, the back-end SOL service decodes the control data according to the RFC6455 specification;
step S804, the back-end SOL service sends the decoded control data through the serial port;
in step S805, the BIOS responds to the control data and then returns the VT100 control code of the changed portion.
That is to say, in this embodiment, when the user controls the cursor (i.e., the focus) of the BIOS setting interface to move through the SOL function, the VT100 control code generated by the change of the image data portion is parsed by the BMC front-end page, and then the corresponding image is directly drawn onto the hidden cache canvas to cover the outdated image at the corresponding position, and then the complete original image data is copied onto the visible canvas; the VT100 control code generated by the change of the cursor data part can be analyzed to generate the final position of the cursor, and the final position is drawn on the visible canvas. Since the hidden cache canvas is refreshed by the VT100 control code generated by the BIOS setting interface operated by the user each time, and the VT100 control code is copied to the visible canvas after the BIOS setting interface is drawn, the original image data on the visible canvas is always complete. And the cursor image is drawn at the final position of the cursor on the visible canvas after the cursor image is drawn at the final position of the cursor, pixels of other areas except the final position of the cursor are not influenced, and therefore the final image displayed to the user is complete and accurate.
Preferably, the present embodiment detects an operation instruction of a user in real time, and when detecting that the user operates the VT100 control code generated by the BIOS setting interface, refreshes the hidden cache canvas, and copies the hidden cache canvas onto the visible canvas after the completion of the drawing. That is to say, only after the operation instruction of the user is detected, the hidden cache canvas is refreshed for drawing, and when the operation instruction is not needed, the cache canvas is not called, so that the fluency of the cache canvas can be well ensured, and the occupation of excessive resources is avoided.

10. A control system for displaying a BIOS setting interface cursor on an SOL page, which employs the control method for displaying a BIOS setting interface cursor on an SOL page according to any one of claims 1 to 9, and comprises:
establishing a connection module, establishing a WebSocket full duplex long connection between a BMC front-end webpage and a back-end SOL service through a network, and then establishing a serial connection between the back-end SOL service and a BIOS;
the BMC front-end webpage analyzes received VT100 control code data after receiving data forwarded by a back-end SOL service through WebSocket full-duplex long connection, wherein the forwarded data is VT100 control code data from a BIOS;
the first judgment module is used for judging whether the analyzed data is image data or not, and if so, skipping to the graph drawing module; if not, jumping to a cursor position determining module;
the image drawing module is used for drawing an image on the hidden cache canvas, copying complete image data to a visible canvas for display, and jumping to the synthetic drawing module after the completion;
the cursor position determining module is used for calculating the final position of the cursor according to the cursor data and jumping to the synthetic drawing module after the final position of the cursor is calculated;
the synthetic drawing module is used for performing synthetic drawing and displaying on the visible canvas;
the second judging module judges whether the back-end SOL service exits or not, and if so, the process is ended; if not, jumping to an SOL response control module;
and the back-end SOL service converts the WebSocket network data into serial port data, forwards the serial port data to the BIOS through serial port connection and returns the serial port data to the data analysis module.
