All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of an information transmission method according to an embodiment of the present application.
The specific steps may include:
s101: creating a shared memory of the server operating system and the baseboard management controller;
the step may create a shared memory 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;
before this step, there may be an information transmission instruction that is sent by the receiving user or other devices, and the server operating system may determine target information to be transmitted according to the information transmission instruction. The present embodiment does not limit the kind of the target information, and may include, for example, network card information, firmware images for upgrading interfaces in the baseboard management controller, storage device mounting information, and the like.
S103: and writing the target information into the shared memory, and controlling the server operating system to send an interrupt notification to the baseboard management controller so that the baseboard management controller reads the target information from the shared memory.
On the basis of determining the target information, the server operating system can write the target information into the shared memory, and after the writing is finished, the server operating system sends an interrupt notification to the baseboard management controller so as to inform the baseboard management controller that the target information can be read from the shared memory after the writing of the information is finished. 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, parameter configuration and the like 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 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. The method and the device do not relate to direct information transmission between the server operating system and the baseboard management controller, but store target information to be transmitted into a shared memory, and the baseboard management controller automatically reads the target information.
Current technology for in-band firmware upgrade of a server mainly relies on tools to transmit firmware images to a baseboard management controller (bmc) via a USB channel or a KCS (an IPMI interface) channel, and the bmc invokes the corresponding interface to upgrade the firmware. The customer does not want to run the upgrade tool under the operating system based on security considerations of himself and security considerations of information, which results in limitations and unreliability of the upgrade tool.
Referring to fig. 2, fig. 2 is a schematic diagram of an in-band firmware upgrade of a server according to an embodiment of the present application, and as shown in fig. 2, in this embodiment, a single shared memory is opened up between an operating system of the server and a baseboard management controller, and a user may copy a firmware image directly to a shared memory area. When the operating system detects that the firmware image meeting the requirements or the formats exists in the shared memory area, a hardware interrupt is initiated to inform the baseboard management controller, the baseboard management controller receives the hardware interrupt and then places the firmware image into the running memory of the baseboard management controller, and a corresponding upgrading interface is selected according to the ID carried by the image, so that corresponding firmware is upgraded. Compared with the IPMI command, the embodiment improves the safety and reliability of the server.
Specifically, the embodiment can implement writing and reading of the firmware mirror image by setting the operation authority of the server operating system and the baseboard management controller, and the specific process is as follows: if a firmware upgrading instruction is received, controlling the server operating system to determine a firmware image according to the firmware upgrading instruction; distributing write access authority to the shared memory for the server operating system, and controlling the server operating system to write the firmware mirror image into the shared memory; and distributing read access authority to the shared memory for the baseboard management controller so that the baseboard management controller reads the firmware mirror image from the shared memory.

Step A3: the operating system copies the firmware image to the shared memory.
Step A4: the operating system triggers a hard interrupt to notify the baseboard management controller.
Step A5: the baseboard management controller obtains the read access right of the shared memory through the secret key.
Step A6: the baseboard management controller copies the firmware image to the baseboard management controller running memory.
Step A7: the baseboard management controller selects a corresponding interface to upgrade corresponding firmware according to the mirror image ID.
The above embodiment provides a design method for acquiring a firmware image under an operating system by a baseboard management controller. By opening up a single shared memory between the operating system and the baseboard management controller, when the operating system runs, the firmware image is put into the shared memory and the BMC is informed of accessing the shared memory by hard interrupt, and the corresponding firmware image is obtained.
The communication mode between the server side management controller and the operating system is mainly IPMI command, which requires running tools or scripts at the operating system side, and the collected network card information is sent to the baseboard management controller by the IPMI command mode, but many industries (such as financial industry) in the market at present do not allow unsafe third party tools running on the server to collect hardware asset information including the network card information based on safety consideration or other factors, which causes barriers to the communication between the baseboard management controller and the operating system.

Step B5: the baseboard management controller obtains the read access right of the shared memory through the secret key.
Step B6: and the baseboard management controller reads the network card information in the shared memory after receiving the hard interrupt.
Step B7: the baseboard management controller processes and displays the network card information in the web page web.
