Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the embodiments of the present invention in detail in conjunction with specific embodiments and with reference to the accompanying drawings.

It should be noted that all the expressions "first" and "second" in the embodiments of the present invention are used to distinguish two entities with the same name but not the same or parameters that are not the same, as shown in "first" and "second" Only for the convenience of presentation, it should not be construed as a limitation to the embodiments of the present invention, and subsequent embodiments will not describe this one by one.

Based on the foregoing objectives, the first aspect of the embodiments of the present invention proposes an embodiment of a method for querying CPLD version information. Figure 1 shows a schematic diagram of an embodiment of a method for querying CPLD version information provided by the present invention. As shown in Figure 1, the embodiment of the present invention includes performing the following steps based on BMC:

S1. Register CPLD query function based on IPMI protocol;

S2, in response to receiving a request for querying CPLD version information, call the CPLD query function according to the request;

S3. Determine the file location for saving the CPLD data based on the mapping relationship between the CPLD parameters in the CPLD query function and the CPLD file;

S4. Obtain the original data of the CPLD version information from the file corresponding to the file location; and

S5. Process the original data to obtain CPLD version information.

Register CPLD query function based on IPMI protocol. The function body that can query CPLD version information based on IPMI protocol registration can specify the function category as netfun=0x3c and the subcommand category as cmdGetCPLDVersionInfo=0x51. The function for querying CPLD version information can be named ipmiReadCPLDEEPROM. In some embodiments, the registration of the CPLD query function based on the IPMI protocol includes: registering a request message structure and a response message structure in the CPLD query function. The parameters of this function are the request message structure and the response message structure. The request message structure includes the offset address offset and the data length length. The response message structure contains version information version.

In response to receiving a request for querying CPLD version information, the CPLD query function is called according to the request. It is used to query the CPLD version information by entering the command line. When the system detects the relevant command for querying the CPLD version information, it can call the registered CPLD query function.

Based on the mapping relationship between the CPLD parameters and the CPLD file in the CPLD query function, the file location for saving the CPLD data is determined. There is a mapping relationship between the CPLD parameter and the file storing the specific CPLD data, and the file location for storing the CPLD data can be determined through the CPLD parameter. For example, in this embodiment, the file location for saving CPLD data may be /sys/class/hwmon/hwmon0/device/version.

Obtain the original data of the CPLD version information from the file corresponding to the file location. After the file location for saving the CPLD data is determined, the original data of the CPLD version information can be obtained from the file corresponding to the file location. In some embodiments, the obtaining the original data of the CPLD version information from the file corresponding to the file location includes: reading the original data of the CPLD version information based on the offset address and the data length in the message structure.

Process the original data to get the CPLD version information. In some embodiments, the processing the original data to obtain CPLD version information includes: performing an AND operation on the three sub-data in the original data with different reference values and shifting them to obtain the main version information and the sub-version information, respectively And the stage version number. The version information of the CPLD in the embodiment of the present invention is composed of three parts: main version information, sub-version information, and phase version number. Ver1 can be used to represent the main version information, ver2 is the sub-version information, and ver3 is the phase version number. In the example, ver1, ver2, and ver3 are all 8-bit binary numbers. ver1 is ANDed with the first reference value, and then shifted to obtain the data of the main version information. In this embodiment, the first reference value can be 0xE0, and the first reference value and ver1 are ANDed and then shifted to the right by 5 Bit to obtain the data of the main version information, for example, ver1 is 01100000, and 11100000 (0xE0) is ANDed to obtain 01100000, and then shifted to the right by 5 bits to obtain 011, that is, the main version information is 3. Similarly, ver2 is to get the data of the sub-version information by AND operation with 0x18, and then shifted to the right by 3 bits, and ver3 is to get the data of the stage version number by performing the AND operation with 0x07.

In some implementation manners, the processing of the original data to obtain CPLD version information further includes: using an identifier to separate the main version information, the sub-version information, and the phase version number, respectively. The identifier can be either "." or "/". Of course, it can also be any other symbol that can produce segmentation. For example, the main version information is 3, the subversion information is 0, and the stage version number is 2. The final data is converted into the 3.0.2 format, and the data is returned through the response message structure version.

The embodiment of the present invention defines the function category and sub-category commands for obtaining CPLD information by registering the CPLD query function. Then call the CPLD query function, read the CPLD device file, parse the CPLD version information, read the file at a specific location to obtain the information, add processing operations to form human-recognizable version information, and finally return the final result through the response message structure CPLD version information.
