The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and quoted from each other on the premise that there is no contradiction.

Referring to Figure 1, a flow chart of steps of an information display method provided by an embodiment of the present invention is shown, which is applied to a basic input and output system. The method may include:

Step 101: Obtain the agreed command word and the target data block from the designated area of the baseboard management controller. The target data block includes the management information of the server.

In the embodiment of the present invention, the designated area is in the SRAM (Static Random Access Memory) of the baseboard management controller. As shown in Figure 4, the baseboard management controller writes the agreed command word and the target data block. into SRAM, and the basic input and output system reads the agreed command word and target data block from SRAM. That is, both the baseboard management controller and the basic input and output system can read and write access to the contents of this designated area. The agreed command word is the baseboard management control The commands agreed upon between the processor and the basic input and output system include shortcut display commands for controlled output.

It should be noted that before the basic input and output system reads the agreed command words and target data blocks from the designated area of the baseboard management controller, the baseboard management controller needs to trigger the SMI interrupt of the system. When the SMI interrupt is used, the CPU must enter SMM. (System Management Mode, system management mode), and requires a memory area SMRAM, so that the CPU stores the register value in SMRAM before entering SMM, then executes the SMl Handler in the BIOS, and then uses the RSM instruction to jump after processing. Return to the original place to continue execution and restore the values of the CPU registers.

In addition, the basic input and output system will also initialize the VGA device of the server before obtaining the agreed command words and target data blocks from the designated area of the baseboard management controller, including after the PCI device enumeration is completed, all PCI devices Traverse the Vendor ID, Device ID and Revision ID to match the onboard VGA device. The specific implementation steps include:

Then, the MMIO (Memory-Mapped Input/Output) of the VGA device will also be checked. Memory mapping input/output) and Video Memory space are allocated and initialized. The clock of the VGA device is also initialized, and the functional modules of the VGA device are initialized to avoid the presence of other information when the VGA device displays the server's management information. Interference affects the work efficiency of operation and maintenance personnel.

Step 102: Parse the agreed command words.

The agreed command words in the embodiment of the present invention are commands agreed upon by the baseboard management controller and the basic input and output system, including shortcut display commands for controlled output, and other commands, such as commands for modifying system parameters and detecting system faults. commands, etc. However, the embodiment of the present invention only allows the VGA device to quickly display the management information of the server when it is determined that the agreed command word is a quick display command, so the obtained agreed command word needs to be parsed.

It should be noted that in a computer, a command refers to an instruction sent to a certain interpreter program in order to complete a specific task. The command word is composed of commands, so by parsing the command word, you can determine what it contains. What kind of command is it?

Step 103: If the agreed command word is a shortcut display command, copy the target data block to the graphics card memory space of the video graphics array VGA device, so that the VGA device displays the management information of the server.

After the embodiment of the present invention determines that the command at this time is a quick display command by parsing the agreed command words, the VGA device resources will be locked to avoid interference from other factors, causing the VGA device to be unavailable and affecting the operation and maintenance work, and then the management information of the server will be included The target data block is copied to the video card memory space of the video graphics array VGA device, so that the VGA device displays the server's management information.

It should be noted that if the agreed command word is not a shortcut display command, the baseboard management controller is controlled to enter the UID button continuous monitoring state, and when it is detected that the UID button status is in the specified state again, the above operation is repeated.

The information display method provided by the embodiment of the present invention is applied to the basic input and output system by obtaining the agreed command word and the target data block from the designated area of the baseboard management controller. The target data block includes the management information of the server; parsing the agreed command word; if If the command word is a shortcut display command, the target data block is copied to the memory space of the graphics card of the video graphics array VGA device, so that the VGA device displays the management information of the server. In the embodiment of the present invention, the management information of the server is set as the target data block. , so that server management information can be obtained through the target data block, without the need for operation and maintenance personnel to first obtain the product serial number of the operation and maintenance equipment and its corresponding management port IP, in order to obtain the server management information, which improves the efficiency of operation and maintenance work. When it is determined that the agreed command word is a shortcut display command, copy the target data block to the graphics card memory space of the video graphics array VGA device, and rely on the data interaction of BIOS and BMC to realize the output display of the server's management information on the VGA device, which is greatly It improves the efficiency of server on-site operation and maintenance work; and from the perspective of user experience, the availability and maintainability of the server's RA S (reliability, availability, maintainability) features have been greatly improved, which can play a role Improve the competitiveness of server products.

Referring to Figure 2, a flow chart of steps of another information display method provided by an embodiment of the present invention is shown, which specifically includes:

Step 202: Determine the graphics card memory space of the VGA device according to the target address.

In the embodiment of the present invention, the basic input and output system initializes the VGA device of the server during the boot process. In order to ensure that the subsequent content displayed through the VGA device only contains the management information of the server, because the management information of the server is stored in the graphics card memory of the VGA device. After the space, the display is called, so the graphics card memory space of the VGA device is initialized, so the location and corresponding content of the graphics card memory space of the VGA device are determined according to the target address.

Step 203: Allocate and initialize the contents of the graphics card memory space of the VGA device.

In the embodiment of the present invention, the content of the memory space of the graphics card of the VGA device is allocated and initialized to prevent interference from other information when the subsequent VGA device displays the management information of the server, affecting the work efficiency of the operation and maintenance personnel.

Usually, initialization means assigning variables to default values, setting controls to default states, and preparing unprepared items.

Step 204: Obtain the agreed command word and the target data block from the designated area of the baseboard management controller. The target data block includes the management information of the server.

Step 205: Parse the agreed command words.

Step 206: If the agreed command word is a shortcut display command, copy the target data block to the graphics card memory space of the video graphics array VGA device, so that the VGA device displays the management information of the server.

However, the VGA device also has other work contents to be displayed. In order not to delay other display work of the VGA device, the embodiment of the present invention uses the VGA device to display the management information. The device's clock sets a time limit, which is accomplished through the VGA device's clock. When the interface of the VGA device is detected and the server's management information is displayed, the clock of the VGA device is started.

Step 208: When it is detected that the clock timing duration of the VGA device reaches the target threshold, copy the data in the cache space to the graphics card memory space of the VGA device.

The embodiment of the present invention uses the clock of the VGA device to calculate the time for the VGA device to display the management information of the server. When the clock timing of the VGA device reaches the target threshold, it is determined that the operation and maintenance personnel at this time have obtained the information. At this time Restore the previous working state of the VGA device, that is, copy the data in the cache space to the graphics card memory space of the VGA device. Among them, the setting time of the target threshold can be 10S, 8S or 15S, which will not delay other work of the VGA device, but also allow operation and maintenance personnel to clearly and fully obtain the management information of the server.

It should be noted that in order for the VGA device to return to its original state (i.e., the previous state) and continue working after displaying the server's management information, the agreed command word and target data block are obtained from the designated area of the baseboard management controller. , also set the following steps:

Lock the current VGA device resources;
