technical field

The invention relates to the field of servers, in particular to a video interface adaptive configuration method, device, equipment and storage medium.

Background technique

With the rise of big data and Internet applications, the application scope of servers is getting wider and wider. The display of servers is based on onboard graphics cards. , there are no performance requirements.

However, with the development of the Internet industry, for better display and performance, the demand for servers equipped with external graphics cards and graphics processing units (Graphics Processing Unit, GPU) is increasing; GPU cards can be understood as data computing cards, They are different from general graphics cards, generally do not display output sockets, etc., and some are just oversized graphics cards (because they are specially used for computing, so the temporary storage of data is relatively large), generally used for computing in enterprises, scientific research and other aspects.

In order to better meet the needs of customers, the VGA display of the server's Basic Input Output System (BIOS) has options to control. The option VGA Priority has two values: Onboard Device and Offboard Device, which are used to switch the GPU configuration. server and external graphics card configuration server. The customer must manually modify the option value, and every time the modification must be saved, the configuration must be saved and then restarted, which is not only time-consuming and labor-intensive, but also if the customer forgets to modify the option, another VGA display will have a black screen.

And with the update of the BIOS version, the default value of the VGA Priority option under BIOS Setup is changed to Onboard Device, but many customers will choose to keep the BIOS setting parameters for upgrade when updating the BIOS version. After the old version is upgraded to the new version, The current value of the option VGA Priority is still Offboard Device. When the server is configured with an external graphics card, the external graphics card displays normally, but when the server is configured with a GPU, after the server is powered on, the monitor is connected to the onboard VGA, and a black screen will be displayed. Open with remote KVM, also shows black screen.

Detailed ways

In order to clearly illustrate the technical features of the solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. The following disclosure provides many different embodiments or examples for implementing different structures of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in different instances. This repetition is for the purpose of simplicity and clarity and does not in itself indicate a relationship between the various embodiments and/or arrangements discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted from the present invention to avoid unnecessarily limiting the present invention.

As shown in FIG. 1, an embodiment of the present invention discloses a video interface adaptive configuration method, including:

When the server is powered on, the basic input output system detects the server connection device ID;

Switch the video interface to the adapter device according to the connected device ID;

The baseboard management controller (Baseboard Management Controller, BMC) obtains and stores the option value of the basic input output system setup;

When the server restarts, the baseboard management controller re-acquires the option values of the BIOS setup, compares the option values of the BIOS setup before and after the restart, and when the comparison result is false, sends a video interface adaptation switch to the BIOS. information.

Specifically, the video interface is a VGA interface.

The detection function of the device ID connected to the server is added to the BIOS code. During the boot process of the server, the BIOS automatically detects all the device IDs of the server. When the device ID of the external graphics card is detected, no matter the current value of the option VGA Priority is Offboard Device or Onboard Device , are displayed on the external graphics card; when the ID of the external GPU device is detected, no matter the current value of the option VGA Priority is Offboard Device or Onboard Device, it is displayed on the onboard graphics card; when the external graphics processor and the external graphics card are both displayed. When the IDs of the external devices do not exist, no matter the current value of the option VGAPriority is Offboard Device or Onboard Device, it will be displayed on the onboard graphics card.

The BIOS option comparison function is added to the BMC code, and the BIOS setup provides options for customers to manually set. After the BIOS update of the server is completed, the BMC will automatically clear the originally stored BIOS option values, automatically obtain and store the BIOS setup option values again; after that, each time the server restarts, the BMC will automatically obtain the BIOS option values again, and combine them with the original stored BIOS option values. The option value is compared, and then the comparison result is sent to the BIOS for subsequent processing. The BIOS option value newly obtained by the BMC overwrites the original stored option value. When the client changes the option value of VGA Priority manually or by using script, the BMC compares the option value of VGA Priority obtained during the server save and restart process with the original stored option value. If the comparison result is false, it sends the BIOS to switch VGA adaptive display. If the BIOS receives the information sent by the BMC, regardless of whether the server has an external graphics card or GPU configuration, it will select the corresponding graphics card to display according to the current value of the BIOS option VGA Priority. When the VGA Priority option value is Offboard Device, the video interface is switched to the external graphics card; when the VGA Priority option value is Onboard Device, the video interface is switched to the onboard graphics card.

As shown in FIG. 2 , an embodiment of the present invention further discloses a video interface adaptive configuration device, including:

The device ID detection unit is used to detect the server connection device ID;

a video interface switching unit, used for switching the video interface to the adaptation device;

The option value acquisition unit is used to acquire and store the option value of the basic input output system setup;

The option value comparison unit is used to compare the obtained option values of the BIOS setup.

The embodiment of the present invention also discloses a video interface adaptive configuration device, including:

memory for storing computer programs;

The processor is configured to implement the steps of the above-mentioned video interface adaptive configuration method when executing the computer program.

The embodiment of the present invention further discloses a storage medium, where a computer program is stored on the storage medium, and when the computer program is executed by a processor, the steps of the above-mentioned video interface adaptive configuration method are implemented.
