In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a card type identification method provided by the present invention, where the card type identification method includes:
s101: receiving a preset number of level signals sent by a server board card in the process of starting a server;
specifically, in consideration of the technical problems in the background art, a set of specific firmware suitable for all board card types can be designed, and as long as the controller where the firmware is located knows the board card type each time the server is powered on, the board card can be initialized by using the firmware corresponding to the board card type in the set of specific firmware.
The preset number may be set autonomously, and the embodiment of the present invention is not limited herein.
The board card may be of various types, such as a motherboard or a backplane, and the embodiment of the present invention is not limited herein.
S102: filling the level signal to a preset position in the level array;
specifically, in consideration of the fact that the resource of the level signal output pins on the server board card is limited, the number of level signals which can be output by the server board card is limited, and the board types which can be represented by a small number of level signals are limited, so that in order to enable the preset number of level signals output by the server board card to represent more board types, the level signals are put into the level array with the number of positions larger than the preset number, so that the board types are represented by combining the level number values at all the positions in the level array, and the representable number of the board types is greatly increased.
Specifically, for example, if the preset number is 3, then 3 level signals can represent 2 at most3g total 8 types of cards, and if 3 level signals are filled into a level array having 7 positions, the level array filled with level signals can represent 2 at most7Individual board card type.
In the embodiment of the invention, a large number of board card types can be represented by combining the level signals output by the board cards and the level arrays, so that the same set of specific firmware can be used for the board cards of such a large number of types, and the normalization of the specific firmware is realized.
S103: determining the board card type corresponding to all values of all positions in the current level array together according to the preset corresponding relation so as to select a specific firmware corresponding to the board card type to initialize the server board card;
specifically, the filling of the level signals into the level array means that more levels of the level array are used to represent more board types, so in the embodiment of the present invention, the board type corresponding to all values at each position in the current level array can be determined according to the preset corresponding relationship.
The combination of the level signals output by each specific type of board card is determined, and when the server is constructed, which positions of the level array to which the level signals of the electric board card need to be filled are also determined, so that the board card type can be represented by a fixed set of values of the level array.
S104: clearing numerical values of all positions in the level array when the server is shut down;
the total number of the positions in the level array is larger than the preset number.
Specifically, in order to correctly determine the type of the board card at the next start, the numerical values at the positions in the level array may be cleared when the server is powered off.
The invention provides a board card type identification method, which can receive a preset number of level signals sent by a server board card, fill the level signals to preset positions in a level array, and finally determine board card types corresponding to all values of all positions in the current level array according to preset corresponding relations.
As a preferred embodiment, the step of filling the level signal into the preset position in the level array specifically includes:
receiving a preset number of level signals through a total number of level receiving ports at the position of the receiving terminal;
and filling each received level signal to the corresponding position of the level array according to the corresponding relation between the level receiving port and the position in the level array.

Specifically, in the embodiment of the present invention, when a worker connects a board card and a processor, the worker needs to accurately connect a level signal output port of the board card and a level receiving port specific to the processor, so that a numerical combination of a finally formed level array corresponds to a type of the board card.
The processor is provided with a plurality of level receiving ports with the total number of positions, wherein the level receiving ports are specially used for receiving level signals, and other signal ports cannot be connected so as to avoid influencing the identification work of the board type.
As a preferred embodiment, the step of filling the level signal into the preset position in the level array specifically includes:
receiving a preset number of level signals through a preset number of level receiving ports of the device;
and filling the received level signals to the specified filling positions of the level array according to the pre-stored specified filling positions.
Specifically, in the embodiment of the present invention, another specific way of filling level signals into a preset position in a level array is provided, and in order to save level receiving ports of a processor under certain circumstances, the level signals may be received only by using the same number of level receiving ports (that is, a one-to-one correspondence relationship), so that, if the received level signals are to be filled into the level array, each received level signal may be filled into an assigned filling position of the level array by using a pre-stored assigned filling position, that is, when a worker designs the server, the assigned filling position may be pre-stored in the processor according to a board type of the server, so that a numerical combination of the finally formed level array corresponds to the type of the board.
Specifically, for better explaining the embodiments of the present invention, please refer to table 1 below, where table 1 is a structure table of a level array provided by the present invention.
TABLE 1
Specifically, in the above level array, Bit 0-6 is 7 positions, GPIO 0-2 is three level signals, and Bit 7 is a check signal (e.g., parity/xor), so that the level signals at each three positions in the level array can express at most 8 types of cards, and the switching positions of the three level signals in the level array (e.g., to Bit 1-3) can further characterize 8 types of cards.
The check signal can also be provided by the board card, so that the processor can check the electrical frequency signal according to the check signal to determine the reliability of the level signal.
