In some embodiments, the firmware version information and the serial number of the GPU may be updated each time the server is powered on; and re-identifying the hardware position of the GPU when the GPU is powered on and started every time.
Fig. 2 is a flowchart of a method for a server to read a GPU according to an embodiment of the present invention. As shown in fig. 2, in the present embodiment, the BMC is used for presenting the GPU complete information. After the power-on and the startup are carried out, the BMC identifies whether GPU equipment is inserted into the hardware slot position or not in an SMBUS mode, and determines the position of the GPU on the hardware. After the BIOS completes the initialization of the equipment, the manufacturer information, the type, the model, the link rate and the link width information of all PCIE equipment can be captured, and meanwhile, the BIOS sends the information to the BMC according to a predefined IPMI SUGON OEM command format. The BMC establishes a corresponding relation table of PCIE and hardware silk screen in advance according to hardware design, identifies the BUS/DEVICE/FUNCTION information of the PCIE equipment according to BIOS to perform one-by-one matching, obtains position information of all the PCIE equipment on hardware, and determines GPU equipment in the PCIE equipment according to BaseClass and SubClass.

In addition, the firmware version information and the serial number of the GPU are updated once at each boot. The GPU equipment does not support hot plug, power-off operation is needed when the GPU equipment is replaced, and after the equipment is replaced, the GPU can be re-identified when the GPU equipment is powered on for the first time. The identification process is carried out again, so that even if the GPUs of different models are replaced, the insertion and placement positions of the GPUs are changed, the display of the GPUs cannot be influenced, and the accuracy and the integrity of GPU information can be guaranteed.
More specifically, referring to fig. 2, after the BMC receives and recognizes that the GPU is actually located at the PCIE interface on the hardware after the first boot is started, the BUS/DEVICE/FUNCTION records of the PCIE are in one-to-one correspondence with the hardware silk-screen information. When the BIOS identifies the information of the PCIE equipment in the process of starting up the computer each time, an IPMI OEM command is used for carrying out data interaction between the BMC and the BIOS, and the acquired information is synchronized to the BMC. The BMC end can determine whether the GPU equipment is the GPU equipment or not through BaseClass and SubClass according to information identified by BIOS, corresponds to the PCIE interface position on actual hardware through BUS/DEVICE/FUNCTION, switches an I2C channel to be positioned to each GPU equipment according to the position information recorded before, reads information inside the GPU through an OOB mode, and displays the information on the web end.
As shown in fig. 2, each time the server is powered on or restarted, the BIOS may identify the BUS/DEVICE/FUNCTION information of the PCIE link where the PCIE DEVICE is located, and may obtain the BaseClass/subcclass information of the PCIE DEVICE according to the standard protocol of the PCIE, so as to determine the type of the PCIE DEVICE. And transmitting PCIE identification information to the BMC according to IPMI SUGON OEM CMD. The BMC establishes an integral corresponding relation between the PCIE and the hardware silk-screen in advance according to the hardware design of the server, and can obtain the position information of the PCIE interface through circulating data of the corresponding table through BusNum, DevNum and FunNum sent by the BIOS. And judging whether the PCIE equipment is GPU equipment or not according to BaseClass and SubClass. When the GPU equipment is identified to be stored, according to the silk-screen position of the hardware, the I2C link information of the hardware where the GPU is located can be determined, interaction with the GPU is achieved through an OOB mode, and the detailed information of the GPU is obtained. And integrating all information, displaying the information on a WEB side, and seeing detailed information of the GPU.
In summary, according to the method provided by the present invention, the BMC can obtain the intuitive screen printing position of the GPU on the hardware through the I2C, the BIOS can obtain part of the information of the GPU, and the BMC can reprocess and improve the GPU information currently available by the BIOS, so as to more intuitively correspond the actual position of the GPU on the hardware to the GPU information and present the GPU information to the client.
