Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present invention, and the embodiments can be mutually combined and referred to without contradiction.

Referring to fig. 1, a flowchart illustrating steps of a method for obtaining device information according to an embodiment of the present invention is shown, where the method may include:

step 101, under the condition that the solidification of the computing core module is detected, a first corresponding relation table between an interface identifier corresponding to each PCIE interface in the computing core module and a first interface address is obtained.

It should be noted that, in the embodiment of the present invention, the present invention is applied to a baseboard management controller (Baseboard Management Controller, BMC), where the baseboard management controller is communicatively connected with a computing core module, an external device module and a basic input/output system, and the BMC is a microcomputer installed on a computer motherboard, and may work independently of a main processor, and is used to monitor and control a hardware state of a server system, and provide a remote management function. The BMC can communicate with various hardware devices on the main board through an I2C bus, an SMBus bus, an SPI bus and the like, monitor related parameters of the server, such as temperature, voltage, fan rotating speed and the like, and further transmit monitored data to preset server management software, so that related personnel can monitor and manage the hardware state of the server remotely, and alarm notification, error diagnosis, restarting operation and the like.

Further, in the embodiment of the present invention, the baseboard management controller, the computing core module, the external device module and the basic input/output system form a device information acquisition system through communication connection, where the system may be a server architecture, and specifically, the external device module is provided with an external device slot, where the external device slot is used for inserting external devices, for example, peripherals such as a network card, a graphics card, and the like.

The computing core module is a computing core of a whole system server architecture, the computing core module comprises at least one central processing unit and PCIE interfaces for expanding peripherals, each PCIE interface corresponds to a unique central processing unit, the PCIE interfaces are high-speed serial interface standards and are used for high-speed communication among a computer main board, the peripherals and other devices, each PCIE interface under the central processing unit is provided with a fixed interface identifier, the interface identifier is a logic identifier given by the central processing unit, and a unique interface address can be given to each PCIE interface through a pull-up resistor in the computing core module.

Specifically, after the solidification of the computing core module may assign an interface address corresponding to each PCIE interface through a pull-up resistor, the interface address corresponding to each PCIE interface in the whole module is fixed, where the pull-up resistor assigns an interface address, for example, four lines connected to one PCIE interface (P0 interface) are all grounded (i.e. the resistor is pulled down entirely), and at this time, the level value is 0000, so that the interface address corresponding to the P0 interface is 0000, and the other PCIE interface (P1 interface) may assign 0 through all pull-down of the first three address bits, and all pull-up assigns 1, at this time, the level value is 0001, so that the interface address corresponding to the P1 interface is 0001.

Therefore, after the BMC detects that the computing core module (i.e. the central processing unit on the motherboard) is cured, the BMC may obtain a first correspondence table between the interface identifier corresponding to each PCIE interface in the computing core module and the first interface address. On the motherboard, PCIE interfaces are used to connect to various hardware devices, interface identifiers are used to uniquely identify each interface, and the first interface address specifies a physical address of each PCIE interface.

Specifically, as shown in table 1, table 1 is a first correspondence table, where the first correspondence table includes PCIE interfaces, and a correspondence between first interface addresses and interface identifiers corresponding to PCIE interfaces, and specific data is not specifically limited in this application, but only one display of the first correspondence table.

TABLE 1 first correspondence table

Further, the interface identifier is a unique interface identifier allocated to the PCIE interface by the central processing unit in the computing core module, where each PCIE interface corresponds to a unique central processing unit. The first interface address is a unique interface address corresponding to the PCIE interface and generated based on solidification of the computing core module, and the interface address corresponds to the interface identifier one by one.

It should be noted that, in the embodiment of the present invention, the interface identifier is a unique interface identifier allocated to the PCIE interface by the central processor in the computing core module, the first interface address is a unique interface address corresponding to the PCIE interface generated based on solidification of the computing core module, and since each PCIE interface corresponds to one interface address and one interface identifier, the computing core module may generate a first correspondence table of the first interface address and the interface identifier, and the BMC obtains the first correspondence table from the computing core module.

Step 102, obtaining a second correspondence table between the position information of the external device slot and the first interface address when detecting that the PCIE interface is connected to the external device slot and the external device is connected to the external device slot.

It should be noted that, in the embodiment of the present invention, it should be clear that PCIE is a high-speed serial interface standard, and is used for extending an external device, where the external device is an external device connected to a server system through an external device slot, for example, an external graphics card, an external hard disk, and so on. When the PCIE interface and the external device slots are connected through the cable, the server system may automatically detect the connection, and when the external device is plugged into the external device slot, the BMC may read, through the I2C signal, a second interface address corresponding to an uplink physical interface connected to each external device slot on the input/output expansion chip of the external device module, and obtain a correspondence between position information of the external device slot and the second interface address, where the integrated circuit bus (Inter-Integrated Circuit, I2C) is a serial communication bus.

Further, the external device slot includes a preset position identifier, and the obtaining the position information of the external device slot includes: and acquiring the position information of the external equipment slot according to the position identification.

Specifically, each PCIE interface has a unique interface address, when the external device is connected to the server through an external device slot, each external device slot corresponds to a piece of location information, the location information may be identified near the chassis or the slot in a tag or silk-screen mode, and the location information is recorded, when each different external device is inserted into a different external device slot, the BMC needs to obtain the actual location information of the external device, so, on the basis of obtaining the first correspondence table, the BMC needs to obtain the correspondence between the location information of the external device slot and the first interface address, and thus, the location information of the external device can be transferred to related personnel or related software for checking the location information of the external device.

Further, each external device slot is connected to an uplink physical interface, and the obtaining the second correspondence table between the position information of the external device slot and the first interface address includes: acquiring the position information of the external equipment slot; reading a second interface address of the uplink physical interface corresponding to each external equipment slot in an input/output expansion chip in an external equipment module through an I2C signal, wherein a corresponding relationship exists between the second interface address and a first interface address corresponding to the PCIE interface connected with the external equipment slot, and the second interface address is the same as the first interface address; and performing comparison processing according to the corresponding relation between the first interface address and the second interface address, and generating a second corresponding relation table. Wherein the second correspondence table includes: the first interface addresses are in one-to-one correspondence with the PCIE interfaces, the second interface addresses are in one-to-one correspondence with the position information of the external device slot, and the PCIE interfaces are in one-to-one correspondence with the position information of the external device slot.

Specifically, the external device SLOT may be represented by SLOT0, SLOT1, SLOT3 … … SLOT, where the external device SLOT is used for inserting an external device, each SLOT has an uplink physical interface, where the uplink physical interfaces may be represented by K0, K1, and K2 … … Kn, and each uplink physical interface corresponds to a second interface address, but the second interface addresses are not solidified by a pull-up resistor, so that the second interface addresses are connected to the input/output expansion chip, and when the PCIE interface of the computing core module and the uplink physical interface of the external device module are connected by a cable, the first interface address corresponding to the PCIE interface of the computing core module is transferred to the uplink physical interface by the cable, and at this time, the second interface address is assigned to the first interface address, and because the second interface address is connected to the input/output expansion chip, and is equivalently transferred to the input/output expansion chip, the BMC can read the second interface address of each uplink physical interface on the input/output expansion chip through an I2C signal.

Therefore, because the second interface address is the same as the first interface address, the BMC obtains the position information of the external device slot, and when the PCIE interface of the computing core module is connected with the uplink physical interface of the external device module by the cable and the external device is connected with the external device slot, the BMC may establish a correspondence between the PCIE interface and the position information of the external device slot according to the first interface address, that is, the BMC obtains the second correspondence table.

Specifically, as shown in table 2, table 2 is a second correspondence table, where the second correspondence table includes the position information of the external device slot to which the external device is connected, the PCIE interface, and the correspondence between the first interface addresses, and the specific data is not specifically limited by the present invention, but only one display of the second correspondence table.

TABLE 2 second correspondence table

And step 103, receiving the equipment information table sent by the basic input and output system under the condition that the equipment information acquisition system is detected to be started.

It should be noted that, in the embodiment of the present invention, the device information obtaining system includes a baseboard management controller BMC, a basic input output system BIOS, a computing core module, and an external device module, where the device information obtaining system may be a server architecture.

Therefore, when the device information acquiring system is started, that is, when the server is started, after detecting that the system is started, the BIOS acquires a device information table, and sends the device information table to the BMC, where the device information table is a table in which all hardware device information in the server system is recorded, and may include a model number, a manufacturer, an interface, and the like of the device. In the embodiment of the invention, the device information table can comprise a device model number, a device serial number, a device specification and an interface identifier corresponding to the device.

Specifically, since the external device is connected under the CPU through the PCIE bus, the BIOS can scan the device information of the external device connected to each PCIE interface under the CPU when the system is started, so in the present invention, the BIOS functions to collect the device information of the server, generate a device information table according to the device information, and transmit the device information table to the BMC, where the BMC processes the data, and then can be used to monitor the running state of the system, predict the device failure, provide a remote management function, and so on.

Specifically, as shown in table 3, table 3 is an equipment information table, the equipment information table includes the external equipment information, the external equipment information includes an equipment model corresponding to the external equipment, the serial number of the external equipment, the specification of the external equipment and the interface identifier corresponding to the external equipment, and the specific data is not specifically limited by the present invention, but only shows one kind of second correspondence table.
