Description
Technical Field
The invention relates to the technical field of servers, in particular to a display card switching method, a server and a storage medium.
Background
At present, a server product generally supports multiple display cards, such as an integrated display card, an external display card, a BMC (baseboard management Controller) display card, and the like.
The integrated display card is integrated inside a CPU of the server, the external display card is connected with the server in an inserting mode through an external PCIe slot provided by the server, and the BMC display card is integrated inside the BMC module.
These different graphics cards each have advantages and disadvantages, such as: compared with an integrated display card and a BMC display card, the external display card has higher processing efficiency, but has larger volume and needs to be inserted into a PCIe slot provided by the server.
Under different conditions, the graphics card switching operation is often performed based on the characteristics of each graphics card. For example: the user switches between the display cards with different display resolutions by combining own preference and application scenes; when the server is switched to the power-saving mode, switching to a display card with lower power consumption; in a factory test link, sequentially switching each display card so as to independently test each display card;
in the prior art, when a plurality of graphics cards are in place, a server only loads a VBIOS (virtual Basic Input/Output System) of a graphics card with the highest priority among the plurality of detected graphics cards at each time of starting, and since each graphics card is designed for different platforms and the priority order thereof is fixed, in order to implement graphics card switching, a user needs to enter a menu option of a BIOS (Basic Input Output System ) to perform manual switching, or modify the priority in a VBIOS file in the corresponding graphics card. However, the two conventional switching methods have the following disadvantages:
1) the switching difficulty is high, the BIOS modification menu option needs to be manually entered or the video card needs to be manually entered to modify the VBIOS file, and certain technical difficulty exists for both users and testers.
2) When the mode of modifying the VBIOS file in the display card is adopted, the manufacturer of the display card is required to assist, and the manufacturer of the display card can not necessarily assist in considering the technical secret problem.
3) The switching operation is easily limited by a hardware platform and mainly exists in intel or AMD platforms, and because the display processing flow and the implementation method of each platform are inconsistent, the implementation process of the specific manual switching operation is inconsistent, and the portability is poor.
4) Time consumption: for a user and a tester, setting, searching an option menu, storing and restarting are required to be manually performed every switching, and much time is spent.

In order to solve the problems of high technical difficulty, requirement of manufacturer assistance, limitation of a hardware platform and time consumption of the conventional manual switching mode, the BIOS program is controlled by adopting an out-of-band management mode. Out-of-band management, i.e. management control information and data information are transmitted through different physical channels, and the control plane and the data plane are completely independent and do not affect each other. By adopting the out-of-band management mode, the BIOS program can be controlled through the control plane channel when running, namely, business processing is carried out through the data plane channel.
Based on this, the video card switching scheme realized by applying the BMC technology provided by the invention comprises the following steps: when the BIOS module is started and detects at least two in-place display card devices, the BMC module determines a target display card to be switched from the in-place display card devices and informs the BIOS module, and then the machine is restarted; and the BIOS module acquires and loads the VBIOS file of the target display card so as to control the output display of the target display card.
Example one

In the list, the display priorities of the display card devices are different, and the display priorities can be set by a user according to requirements.
And 103, setting display priorities corresponding to the SSIDs/SVIDs of all the in-place display card devices by the BMC module, and returning the SSIDs/SVIDs with the highest display priorities to the BIOS module.
Based on the preset first priority display list, the BMC module can search the corresponding list item of each in-place display card device according to the SSID/SVID, and set the display priority corresponding to the SSID/SVID of each in-place display card device according to the search result.
In other embodiments, the BMC module may also directly set the display priority corresponding to the SSID/SVID of each in-place graphics card device according to actual conditions, without referring to a preset first priority display list, which is not limited in the present invention.
After the setting operation of the display priority corresponding to the SSID/SVID of each in-place display card device is completed, the BMC module can further generate a corresponding second priority display list according to the setting operation, the second priority display list is sent to the BIOS module, the BIOS module controls and displays the display list to a user, the user can know the type and the corresponding display priority of the current in-place display device, and a foundation is laid for the user to adjust the display priority required by the next switching operation.
And step 104, determining the in-place display card equipment corresponding to the received SSID/SVID as a target display card by the BIOS module, and acquiring and loading a VBIOS file of the target display card to control the target display card to output and display.
The BIOS module may obtain the VBIOS file of the target graphics card in various ways, which are not limited specifically.
For example, the VBIOS file of each display card device supported by the server may be pre-stored in the BMC module or the SD card/EMMC connected to the BMC module, and the BIOS module may extract the VBIOS file of the target display card from its own cache or the SD card/EMMC directly, and send the VBIOS file to the BIOS module. Of course, the BIOS module may also obtain the VBIOS file directly from the target graphics card itself.
It should be noted that, in this embodiment, the BMC module and the BIOS module perform information interaction by using an IPMI (Intelligent platform management Interface) protocol.
Based on the display card switching method, when the user executes the next switching, the subsequent BIOS module can automatically determine the new target display card to be switched and completely start and load the target display card only by modifying the display priority information corresponding to each display card device in the first priority display list in the BMC module. The user does not need to manually enter a BIOS menu to modify and adjust the display options, and does not need to enter each display card to set the priority, so that the technical difficulty of switching operation is greatly reduced, the dependency on manufacturers of the display cards is relieved, the switching operation speed is greatly improved, and the method has strong transportability to different platforms.
Example two
Referring to fig. 2, based on a solution idea of determining a target graphics card to be switched from an in-place graphics card device through a BMC module, the present embodiment provides another graphics card switching method, including:
Different from the first embodiment, in the second embodiment, the BIOS module directly encapsulates the display option interface for setting the target display card, and reserves the display option interface for the BMC module, the BMC module can acquire the currently loaded and operated display card device through the display option interface, and modify the currently loaded and operated display card device into the target display card through the display option interface when necessary, and after the BIOS module is restarted, the BIOS module can automatically reload the VBIOS file of the target display card, and complete switching is performed.
