Step 102: and when a first instruction of the BMC controller is received, establishing data connection between the BMC controller and the target component.
The first instruction of the BMC controller may be: the BMC controller may read data from the target component, or may write data into the target component, so that after receiving the first instruction of the BMC controller in this embodiment, the BMC controller responds to the first instruction to establish a data connection for data interaction between the BMC controller and the target component.
Step 103: and when a second instruction of the system controller is received, establishing a data connection between the system controller and the target component.
The system controller is a controller of the BMC controller and a server system to which the system controller belongs. The second instructions of the system controller may be: the instruction for the system controller to read data from the target component may be an instruction for the system controller to write data to the target component. Therefore, in this embodiment, after receiving the second instruction of the system controller, the second instruction is responded to establish a data connection for data interaction between the system controller and the target component.
It can be known from the foregoing solution that in the control method provided in the first embodiment of the present invention, a video controller is integrated in a BMC controller, and an accessible target component, such as a display or a memory, is set in the video controller, so that when an instruction of the BMC controller is received, a data connection between the BMC controller and the target component is established, so that the BMC controller can interact with the target component, and when the instruction of the system controller is received, a data connection between the system controller and the target component is established, so that the system controller can interact with the target component, thereby in this embodiment, the BMC controller and the system controller can share the target component by using the video controller, so as to implement the interaction between the BMC controller and the target component, and there is no need to use another machine to access the web of the BMC, and no need to obtain the IP address of the BMC in advance, the complexity of the realization of the interaction scheme is obviously reduced, and the interaction efficiency is improved.
In a specific implementation, the target component may be a register in the video controller, that is, a unit capable of storing data, and accordingly, referring to fig. 2, it is an implementation flowchart of a control method provided in the second embodiment of the present invention, where the step 102 may be implemented by:
step 121: and establishing data connection between the BMC controller and the register through an internal bus of the BMC controller so that the BMC controller can access the data in the register.
In this embodiment, after the data connection between the BMC controller and the register is established through the internal bus of the BMC controller, the BMC controller may access the data in the register, for example, the BMC controller may perform a control action such as initialization on the video controller through the register, so as to realize data input between an input device and the BMC controller.
Accordingly, the step 103 can be implemented by:
step 131: and establishing data connection between the system controller and the register through a PCIE bus so that the system controller can access the register.
That is to say, in this embodiment, after the data connection between the system controller and the register is established through the PCIE bus, the system controller can access the data in the register through the PCIE bus, for example, the system controller can perform control actions such as initialization on the video controller through the register, so as to implement data input between the input device and the system controller.
In other words, in this embodiment, the video controller and the register thereof in the BMC controller are used to share the input device of the server system, so that the BMC controller can interact with the input device of the server system.
In a specific implementation, the target component may be a display buffer unit in the video controller, that is, a unit capable of performing display content caching, and accordingly, referring to fig. 3, it is an implementation flowchart of a control method provided in the third embodiment of the present invention, where the step 102 may be implemented by the following steps:
step 122: and establishing a mapping relation between a display buffer space in the display buffer unit and a memory space of the BMC controller, so that the BMC controller writes the first content into the display buffer space.
Step 123: and transmitting the first content in the display buffer space to a display for displaying.
That is to say, in this embodiment, the display buffer unit is mapped to the memory space of the BMC controller, and then a mapping relationship of the space between the display buffer unit and the BMC controller is established, so that the BMC controller can access the display buffer unit, for example, the BMC controller can write the first content into the display buffer space of the display buffer unit, and then the content in the display buffer space can be transmitted to the display of the server system for displaying, so as to implement data interaction between the BMC controller and the display of the server system, that is, the BMC controller outputs the first content to the display of the server system for displaying.
Accordingly, the step 103 can be implemented by:
step 132: and establishing a mapping relation between a display buffer space in the display buffer unit and a memory space of the system controller so that the system controller writes second content into the display buffer space.
Step 133: and transmitting the second content in the display buffer space to a display for displaying.
That is to say, in this embodiment, the display buffer unit is mapped to the memory space of the system controller, and then a mapping relationship of the space between the display buffer unit and the system controller is established, so that the system controller can access the display buffer unit, for example, the system controller can write the second content into the display buffer space of the display buffer unit, and then the content in the display buffer space can be transmitted to the display of the server system for displaying, so as to implement data interaction between the system controller and the display of the server system, that is, the system controller outputs the first content to the display of the server system for displaying.
As can be seen from the above, in this embodiment, the display buffer unit is shared between the system controller and the BMC controller, and the display buffer space of the display buffer unit is mapped to the memory space of the BMC controller and the memory space of the video controller, so that both the system controller and the BMC controller can access the display buffer unit, that is, corresponding content is written into the display buffer space of the display buffer unit, and then the video controller outputs the content in the display buffer space to the display, so that both the system controller and the BMC controller can output the content to the display for displaying, thereby achieving the purpose that the system controller and the BMC controller share the display of the server system.
It should be noted that, in the above example, the priority of writing into the display buffer space by the BMC controller is higher than the priority of writing into the display buffer space by the system controller. That is to say, in order to solve the problem of the conflict between the use of the display by the system controller and the BMC controller, in this embodiment, the priority of the BMC controller may be set to be higher than that of the system controller, and once the first instruction of the BMC controller is received, that is, the display control of the BMC controller to the display is started, the BMC controller is only allowed to write data into the display buffer space in the display buffer unit, and the data written into the display buffer space by the system controller is overwritten by the content written by the BMC controller.
