The core of the application is to provide a data interaction method and device, an electronic device and a computer readable storage medium, the BIOS can perform subsequent starting processes after storing data in a storage area of a controller without waiting for the completion of the starting of the BMC, and the starting time of the BIOS is shortened.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 illustrating steps of a data interaction method provided in the present application, where the data interaction method includes:
s101: receiving data sent by a BIOS;
specifically, the data interaction between the BIOS and the BMC is realized through the controller, in order to save hardware cost, the controller may select the CPLD, and in the server, the CPLD is connected with the BMC through the I2C and is connected with the BIOS through the ESPI, so that a data transmission path between the CPLD and the BMC or the BIOS does not need to be established independently, and hardware cost is further saved, which is described below by taking the CPLD as an example.
Specifically, after the server is powered on, the CPLD is started, and it can be understood that the starting process of the CPLD is not affected by the starting process of the BIOS, and when the CPLD is started, the BIOS is started, and the data which needs to be sent to the BMC is arranged and sent to the CPLD by the BIOS. Because the BIOS does not need to directly perform data interaction with the BMC, after the BIOS sends the data to be sent to the BMC to the CPLD, the BIOS can perform a subsequent starting process, thereby shortening the BIOS starting time.
S102: and storing the data into the corresponding storage area, and generating prompt information so that the BMC acquires the data from the storage area after detecting the prompt information.
Specifically, after receiving the data sent by the BIOS, the CPLD stores all the data in the corresponding storage area, and then generates a prompt message, and after the BMC is started, the CPLD actively detects whether there is a prompt message, and if so, acquires the corresponding data from the cache area of the CPLD, and completes data interaction between the BIOS and the BMC. The storage area may be a UFM (user Flash Memory) in the CPLD.
It can be seen that, in this embodiment, after the BIOS is started, data to be sent to the BMC is temporarily stored in the storage area of the controller, and the controller generates a prompt message to prompt the BMC to acquire the data from the storage area of the controller, so as to complete data interaction between the BIOS and the BMC.

as an alternative embodiment, the process of receiving data sent by the BIOS includes:
receiving data sent by a BIOS according to a predefined format;
the data interaction method further comprises the following steps:
and after acquiring the data from the storage, the BMC analyzes the data according to a predefined format.
It can be understood that the data format of interaction between the BIOS and the BMC needs to be predefined, that is, the BIOS encapsulates the data according to a predefined format, and then sends the encapsulated data to the CPLD, where the predefined format may include data type, field, data sending sequence, size, and the like. And after acquiring the data from the storage area of the CPLD, the BMC analyzes the data according to a predefined format and displays the data.
As an optional embodiment, after receiving the data sent by the BIOS and before storing the data in the corresponding storage area, the data interaction method further includes:
verifying the data;
the process of storing data into the corresponding storage area comprises the following steps:
and storing the data which is successfully verified to the corresponding storage area.
Specifically, in order to improve the security of data interaction, after the CPLD receives data sent by the BIOS, the data is verified, the data that is successfully verified is stored in the storage area, and the data that is failed in verification is discarded.
As an alternative embodiment, after the BIOS encapsulates the data according to the predefined format, the encapsulated data is compressed by zlib (a function library for providing data compression), and then encrypted and signed by a digital certificate, and then sent to the CPLD through the ESPI interface. Correspondingly, the verification operation performed by the CPLD after receiving the data includes integrity verification and security verification, and the verification can be specifically realized through the MD5 or hash, and is selected according to the actual engineering requirement, which is not specifically limited herein.
As an alternative embodiment, the process of generating the prompt message includes:
and adjusting the interface state of the GPIO used for being connected with the BMC on the controller to be a target state.
Specifically, the controller is provided with a GPIO specially connected to the BMC for prompting the BMC to acquire data, the CPLD stores the data in the storage area and adjusts an interface state of the GPIO to a target state, where the target state may be a low level state, that is, after the CPLD stores the data in the storage area, the GPIO is pulled down to prompt the BMC to acquire the data, and after the BMC is started, the controller detects that the GPIO is pulled down, the CPLD acquires the data from the storage area of the CPLD.
To sum up, the BMC and the CPLD can communicate with each other based on the current server, the BIOS and the CPLD can also communicate with each other, the CPLD has the UFM module for temporarily storing data, the BIOS transmits the data to the CPLD first, the CPLD performs integrity check and security check on the data, the data that is successfully checked is temporarily stored in the UFM, then the GPIO between the BMC and the GPIO is pulled down, and the BMC reads the temporarily stored data from the CPLD through I2C after detecting that the GPIO is pulled down after starting, thereby completing data interaction. In the whole interaction process, the BIOS can complete data transmission interaction without waiting for the completion of the start of the BMC.
