The method provided by the embodiment of the invention can be applied to any needed electronic equipment, for example, the electronic equipment can be a server, a terminal and the like, is not particularly limited, and is convenient to describe and is called as the electronic equipment for short hereinafter.
According to an aspect of the embodiments of the present application, a method embodiment of a method for detecting a position of a PCIe device is provided. Fig. 1 is a flowchart of a method for detecting a position of a PCIe device according to an embodiment of the present application, where, as shown in fig. 1, the method includes:
step S11, detecting whether each hardware expansion board card has an accessed PCIe device currently or not, and obtaining a detection result, wherein the hardware expansion board card is deployed on a server and is in communication connection with a baseboard management controller.
The method provided by the embodiment of the application is applied to a baseboard management controller (Baseboard Management Controller, abbreviated as BMC) in the server, and the baseboard management controller can realize the functions of relevant control, information supervision and the like of the server, so that the method is a platform for intuitively presenting server information. The baseboard management controller is connected with a hardware expansion board card (Riser card) in the server by adopting an i2c link, the hardware expansion board card is connected with a central processing unit of the server, namely, one central processing unit is connected with at least one hardware expansion board card, one hardware expansion board card can be connected with a plurality of PCIe devices, in addition, EEPROM (electrically-powered-down not lost storage unit) is arranged on the hardware expansion board card, and data are stored through the EEPROM.
It should be noted that, the server uses a hardware expansion board card to implement PCIe device number expansion, and one hardware expansion board card may expand 3 transmission channels (channels), where each transmission Channel is connected to one PCIe device. Typically, a server may carry 4 hardware expansion boards, and may be collocated with a total of 12 PCIe devices. Based on this, in the embodiment of the present application, the baseboard management controller is in communication connection with the hardware expansion board card in the server, so that the baseboard management control is convenient to obtain the connection information of the hardware expansion board card of the server, that is, which central processing unit the hardware expansion board card is connected to, and which PCIe devices are connected to the hardware expansion board card. Finally, the baseboard management controller can display the position information (CPU serial number, riser serial number and Channel serial number) of each PCIe device, so that the customer can conveniently position the device.
In the embodiment of the application, detecting whether each hardware expansion board card has an accessed PCIe device currently or not to obtain a detection result, wherein the detection result comprises the following steps of A1-A2:
and step A1, detecting the current slave address of the hardware expansion board card by using a communication bus.
In this embodiment of the present application, the baseboard management controller detects the current slave address (slave address) of the hardware expansion board card by using the i2c communication bus, and detects that the slave addresses of different types of devices are different, and if the baseboard management controller detects the slave address of the hardware expansion board card by using the i2c communication bus, it can determine that the hardware expansion board card currently has an accessed PCIe device.
It should be noted that, the performance of the server is related to the PCIe device mounted in addition to the CPU, for example, the PCIe device such as a disk array (Redundant Arrays of Independent Disks, abbreviated as RAID), a graphics processor (Graphics Processing Unit, abbreviated as GPU), a network interface controller (network interface controller, abbreviated as NIC), a field programmable gate array (Field Programmable Gate Array, abbreviated as FPGA), a host bus adapter, and the like, and the addresses of the slaves of the different types of devices are different.
And step A2, determining whether the hardware expansion board card has the accessed PCIe equipment currently based on the slave address, and obtaining a detection result.
In the embodiment of the application, determining whether the hardware expansion board card has the accessed PCIe device currently based on the slave address, obtaining a detection result includes: and under the condition that the slave address is empty, the detection result is that the hardware expansion board card does not currently have the accessed PCIe equipment. Or if the slave address is not null, the detection result is that the hardware expansion board card currently has the accessed PCIe device.
It should be noted that, after the PCIe device accesses the hardware expansion board card through the transmission channel, the slave address is reported to the hardware expansion board card, so the baseboard management controller determines whether the PCIe device that is accessed exists in the hardware expansion board card by scanning the slave address. If the slave address is null, each transmission channel of the hardware expansion board card is not accessed to PCIe equipment currently, so that the detection result is that the hardware expansion board card is not accessed to PCIe equipment currently. If the slave address is not null, the transmission channel of the hardware expansion board card is accessed to PCIe equipment.
And step S12, determining the hardware expansion board card currently accessed to the PCIe device as a target hardware expansion board card by using the detection result.
In the embodiment of the present application, since at least one central processor is disposed in the server, and meanwhile, one central processor may be associated with a plurality of hardware expansion boards, the baseboard management controller may count a detection result of each hardware expansion board, and determine that the detection result is that the hardware expansion board currently accessed to the PCIe device is the target hardware expansion board. Therefore, subsequent positioning of PCIe devices accessed on the target hardware expansion board card is facilitated.
And S13, recording the device position information of PCIe devices accessed by the target hardware expansion board card.
In the embodiment of the application, the recording of the device location information of the PCIe device accessed by the target hardware expansion board card includes the following steps B1-B2:
and B1, acquiring access information of PCIe equipment.
In an embodiment of the present application, obtaining access information of a PCIe device includes: and scanning each central processor in the server, the hardware expansion boards associated with the central processor and the transmission channels of each hardware expansion board in sequence to obtain the access information of the PCIe equipment. Wherein, the access information includes: and the PCIe device is connected with the target transmission channel of the target hardware expansion board card.
In the embodiment of the application, since the baseboard management controller is connected with the hardware expansion board card, the central processing unit on which the target hardware expansion board card is deployed cannot be perceived, and the PCIe device accessed on which transmission channel of the target hardware expansion board card cannot be perceived. Therefore, in order to accurately position the relation between the PCIe equipment and the target hardware expansion board card, a thread is newly added in the baseboard management controller, and after the baseboard management controller determines the target hardware expansion board card, the baseboard management controller sequentially scans through the thread according to the sequence of the central processing unit, the hardware expansion board card and the transmission channel. And obtaining access information of the PCIe device. The access information includes: and the PCIe device is connected with the target transmission channel of the target hardware expansion board card.
As an example, as shown in fig. 2, the server is currently deployed with two central processing units, where the two central processing units are respectively CPU0 and CPU1, the hardware expansion board associated with CPU0 has Riser card 0 and Riser card 1, and the hardware expansion board associated with CPU1 has Riser card 2 and Riser card 3. And 3 transmission channels are respectively arranged on the Riser card 0, the Riser card 1, the Riser card 2 and the Riser card 3.
The detection result shows that PCIe devices are connected to the Riser card 1 and the Riser card 2, when the baseboard management controller scans, the CPU0 and the CPU1 are scanned first to obtain that the hardware expansion board associated with the CPU0 is provided with the Riser card 0 and the Riser card 1, the hardware expansion board associated with the CPU1 is provided with the Riser card 2 and the Riser card 3, and because PCIe devices are connected to the Riser card 1 and the Riser card 2, the baseboard management controller only needs to scan the transmission channels deployed by the Riser card 1 and the Riser card 2 to obtain that the transmission channels on the Riser card 1 and the Riser card 2 are connected with the PCIe devices. The target central processing unit included in the finally obtained access information is: CPU0 and CPU1, the target transmission channels are Channel0 and Channel1 of the Riser card 1, and Channel1 and Channel2 of the Riser card 2.
And step B2, generating device position information by using the access information.
In an embodiment of the present application, generating device location information using access information includes: acquiring a first identifier corresponding to a target central processing unit, a second identifier corresponding to a target hardware expansion board card, and a third identifier of a target transmission channel of a PCIe device connection target hardware expansion board card; the second identifier and the third identifier generate device location information based on the first identifier.
In this embodiment of the present application, the first identifier corresponding to the target central processing unit is the number of the target central processing unit, for example: 0, 1..n. The second identifier corresponding to the target hardware expansion board is the number of the target hardware expansion board, for example: 0, 1..m. The third identifier corresponding to the target transmission channel is the number of the target transmission channel, for example: 0, 1..p. And then the first mark, the second mark and the third mark are arranged according to the preset priority, so as to generate the equipment position information. The preset priority is that the priority of the central processing unit is larger than the priority of the hardware expansion board card, and the priority of the hardware expansion board card is larger than the priority of the transmission channel.
Step S14, writing the device position information into the field replaceable unit of the target hardware expansion board card.
In the embodiment of the application, after generating the device position information, the baseboard management controller writes the device position information into the EEPROM in the hardware expansion board card for storage. And the device position information can be conveniently and quickly read when the device position information is transmitted subsequently.
As one example, when the baseboard management controller scans for PCIe devices present on Riser card 0 of CPU0, device location information is generated: 00-00-01, and then writing the device position information into the EEPROM of the Riser card, wherein the writing content is 00-00-01. Wherein, the first group of numbers 00 represents CPU0, the second group of numbers 00 represents Riser card 0, the third group of numbers are expressed in hexadecimal, if 01 represents that Channel0 exists PCIe device, 02 represents that Channel1 exists PCIe device, 04 represents that Channel2 exists PCIe device, and 03 represents that Channel0 and Channel1 exist PCIe device. Thus, detailed location information of the PCIE device is obtained.
According to the method provided by the embodiment of the application, the target hardware expansion board card which is deployed in the server and accessed to the PCIe equipment is detected after the server is electrified by the baseboard management controller, meanwhile, the equipment position information of the PCIe equipment accessed to the target hardware expansion board card is generated, and the equipment position information is written into the field replaceable unit of the target hardware expansion board card, so that the subsequent reading of the field replaceable unit and the transmission of the equipment position information to the basic input and output system are facilitated, and the problem that the Genoa platform of AMD cannot transmit the position information of the PCIE equipment due to hardware limitation is solved.
In an embodiment of the present application, the method further comprises the following steps C1-C3:
step C1, receiving IPMI command from basic input/output system.
And step C2, in response to the IPMI command, reading the equipment position information from the field replaceable units of the hardware expansion boards.
And step C3, transmitting the equipment position information to the basic input and output system.
In this embodiment of the present application, after the server is powered on, the bios in the server sends an IPMI command to the baseboard management controller, where the IPMI command is as follows: get PCIE Param ipmitool raw 0x3c 0x51+ (Riser Number).
After the baseboard management controller responds to the IPMI command, the baseboard management controller and the hardware expansion boards are connected by adopting a communication bus, so that the baseboard management controller can directly read the equipment position information from each hardware expansion board and send the equipment position information to the basic input/output system.
The method provided by the embodiment of the application self-defines the IPMI command, realizes that the in-band and out-of-band PCIe device position information can be transmitted, and directly reads the content in the field replaceable unit of the Riser card and converts the content into data transmission. In addition, the basic input/output system sends the IPMI command to acquire the device position information of each Riser card associated PCIe device, and then presents the device position information in a Setup option to meet the requirements of clients.
