Description

Method, system, terminal and storage medium for polling and collecting bus device location information

technical field

The present invention relates to the technical field of big data service platforms, in particular to a method, system, terminal and storage medium for polling and collecting bus device location information.

Background technique

The PCIE asset information function is to collect the relevant information of the PCIE device through the BIOS, send it to the BMC, and then display it to the WebUI interface by the BMC. An important information in this function is the location information of the device. Through the location information, the user can The specific equipment corresponds to the silk screen on the machine, so as to correspond to the specific position on the machine, which is convenient for machine maintenance, fault location, and replacement of accessories.

In the design of the existing solution, the asset information function will be triggered by the event of loading and executing the startup device, collect relevant information, send it to the BMC, and then display it on its WebUI interface by the BMC. A boolean variable is designed in the location information data structure of the bus device to record whether the location information has been associated with the device. It is matched with other devices, resulting in inaccurate information.

When the startup item is loaded for the first time after the server is started, the startup bus device is found and the startup is successful, and the asset information function is only triggered once. When loading to a bus device, polling is required to start the bus device loading (including but not limited to triggering the startup item polling function provided by the BIOS), the asset information function will be executed once with each polling, and the asset information will be in The previous data will be refreshed after re-execution. Due to the design of Boolean variables in the bus device location information data structure, after the first attempt to start, the location information of all actual bus devices is marked as processed, and no longer participates in subsequent processing, resulting in subsequent startups without getting the bus The location information of the device, the location information field of the PCIE device asset information on the BMC WebUI will all be blank.

As shown in Figure 1, the method includes:

Step 110, constructing the variable structure of each bus device;

Step 120, marking the location information collection situation of each bus device by setting the storage value of the variable structure;

Step 130: Determine whether to collect the location information of the corresponding bus device according to the location information collection situation.

In order to facilitate the understanding of the present invention, the method for polling and collecting bus device location information provided by the present invention is further described below based on the principle of the method for polling and collecting bus device location information according to the present invention and in conjunction with the embodiments.

Specifically, the method for polling and collecting bus device location information includes:

S1, construct the variable structure of each bus device.

Define a variable structure (UEFI Variable) for the bus device. When there are multiple bus devices in the server, you need to create a variable structure for each bus device, and generate the corresponding device serial number (or device name) according to the bus device. The structure number of the variable structure, and the structure number is used as the corresponding variable structure name. In this way, a one-to-one mapping relationship between the bus device and the variable structure is established through the structure number-device serial number.

The attribute of the variable structure is that it can be accessed in both Run Time and Boot Service phases, and is saved in the memory and BIOS NVRAM area, so that the Variable data can be accessed at any time.

S2. Mark the location information collection situation of each bus device by setting the storage value of the variable structure.

In this embodiment, the initial value of the variable structure is set to 0, and the change value is 1. First initialize the value of this variable structure to 0 before the location information is collected. The variable structure is used to record the status of whether the asset information function has been executed in the handler function of the startup event, and the value of the global variable will be maintained during the process of polling the startup item. When the location information of a bus device is collected, use the SetVariable function to assign the variable structure to 1.

S3. Determine whether to collect the location information of the corresponding bus device according to the location information collection situation.

Each time a bus device is polled, the processing function of the start event will be executed once. In the processing function, before executing the asset information function, use the GetVariable function provided by the UEFI specification to read the value of the variable structure. If it is 0, then Perform asset information processing (that is, read the location information of the bus device, upload the location information to the BMC, and the BMC will generate the asset information of the bus device according to the location information), and use the SetVariable function to assign the variable to 1; If the value of the variable structure is 1, the asset information processing will no longer be performed, so that the asset information function is executed only once in the polling startup, so as to ensure the correct transmission and display of the location information, and will not be emptied; here 0 and 1 , can also be replaced by other different data.
