All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of an information transmission method according to an embodiment of the present disclosure.
The specific steps may include:
s101: establishing a shared memory of a server operating system and a base plate management controller;
in this step, a shared memory may be created between the server operating system and the baseboard management controller, where the shared memory is an independent memory space outside the server operating system and the baseboard management controller, and the shared memory is used to store information that the server operating system needs to transmit to the baseboard management controller.
S102: if an information transmission instruction is received, determining target information according to the information transmission instruction;

On the basis of determining the target information, the server operating system may write the target information into the shared memory, and after the target information is written, the server operating system sends an interrupt notification to the baseboard management controller, so as to notify the baseboard management controller that the target information can be read from the shared memory after the target information is written. After receiving the interrupt notification, the baseboard management controller can read the target information from the shared memory, so as to perform operations such as firmware upgrade and parameter configuration by using the read target information.
In this embodiment, a shared memory is created between the server operating system and the baseboard management controller, and after receiving the information transmission instruction, the server operating system determines target information that needs to be transmitted to the baseboard management controller, and writes the target information into the shared memory created before. The server operating system instructs the baseboard management controller to read the target information from the shared memory by sending an interrupt notification to the baseboard management controller. According to the scheme, information is not directly transmitted between the server operating system and the baseboard management controller, target information to be transmitted is stored in the shared memory, and the baseboard management controller automatically reads the target information.
The existing technology for upgrading the firmware in the server band mainly depends on a tool to transmit a firmware image to a substrate management controller through a USB channel or a KCS (Intelligent platform management System) channel by using an IPMI command, and the substrate management controller recalls the corresponding interface to upgrade the firmware. The customer does not want to run the upgrade tool under the operating system based on its own security considerations and information security considerations, which leads to limitations and unreliability of the upgrade tool.

When the operating system detects that a firmware image meeting requirements or formats exists in the shared memory area, the operating system initiates hardware interruption to notify the baseboard management controller, and after the baseboard management controller receives the hardware interruption, the firmware image is put into the running memory of the baseboard management controller, and a corresponding upgrading interface is selected according to the ID carried by the image to upgrade the corresponding firmware. Compared with the IPMI command, the safety and reliability of the server are improved.
