Therefore, it is particularly important to correctly identify PCIE devices. Only when asset information is correctly identified can it be preliminarily determined that the PCIE device has been acquired.

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the server, BIOS and BMC are the two main firmwares of the server. There are generally two ways for the upper management system in the related method to obtain the asset information of the PCIE device. One is that the BIOS reads the configuration space of the PCIE device to obtain the asset information of the device, stores it in a certain storage space, and then the BMC grabs the information from the storage space, parses the captured information, and displays it in the upper management system after the parsing is completed; the other is that the BMC directly obtains the asset information by command through the SMBUS / I2C method or the MCTP protocol, and then parses it according to the read information and displays it to the upper management system.

[0027] First, the first method relies on BIOS. During the server startup process, BIOS and BMC are initialized separately. If a timeout occurs during the interaction process when capturing and storing information, BMC will not be able to capture normal information, or BIOS will have deviations when reading the PCIE device configuration space, which will also cause the BMC to capture incorrect information. The second method only uses BMC to issue commands to obtain asset information, but if the current PCIE device is not initialized, it will also cause the information to be unable to be correctly obtained or timeout. Both methods will cause the upper-level software to be unable to obtain accurate asset information.

[0028] In view of the defects of the related methods, the present invention proposes a verification method for asset information. Figure 1 It is a flow chart of the verification of asset information provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 110, obtaining first asset information of multiple PCIE devices in the target server from the shared memory space of the target server, wherein the first asset information of the multiple PCIE devices in the shared memory space is obtained based on BIOS reading the configuration space of the multiple PCIE devices; Step 120, based on querying the register in the central processing unit, obtaining the second asset information of the plurality of PCIE devices from the register; Step 130, comparing the first asset information with the second asset information, verifying the asset information of each PCIE device, and classifying and storing the asset information of each PCIE device based on the verification result.

[0029] The execution subject of the asset information verification method provided by the present invention can be an electronic device, a component in an electronic device, an integrated circuit, or a chip. The electronic device can be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The non-mobile electronic device can be a server, a network attached storage (NAS), or a personal computer (PC), etc., which is not specifically limited by the present invention.

[0030] The following takes a baseboard management controller (BMC) executing the asset information verification method provided by the present invention as an example to describe the technical solution of the present invention in detail.

[0031] In step 110, first asset information of multiple PCIE devices in the target server is obtained from the shared memory space of the target server, and the first asset information of multiple PCIE devices in the shared memory space is obtained based on BIOS reading the configuration space of multiple PCIE devices.

[0032] Optionally, the BMC may rely on the BIOS to obtain the asset information of the PCIE device. The first asset information acquisition process diagram may be as follows: Figure 2 The first asset information acquisition process provided by the present invention is shown in a schematic diagram. The target server is powered on, the system starts to boot, and the BIOS is loaded into the memory as the first software component in the boot process. The BIOS starts to initialize the PCIe bus and scans the devices on the PCIe bus. The scanning process involves traversing each slot on the bus to detect whether there is a PCIe device connected. For each detected PCIe device, the BIOS can read its configuration space (ConfigurationSpace). The configuration space contains key data such as the device's identification information, function code, resource requirements, etc.

[0033] BIOS parses the data read from the configuration space and extracts the first asset information of the PCIE device. The first asset information includes the manufacturer ID, device ID, class code, subclass code, programming interface, etc. of the device. BIOS saves the parsed first asset information to a shared memory space, which can be a device such as a memory or hard disk. BMC can use general commands to read the PCIE device information in the shared memory space. Specifically, BMC obtains the PCIE device information of the PCIE device from BIOS through the shared memory space. The obtained PCIE device information includes the existence, location, model, status, etc. of the device. BMC parses and records the obtained PCIE device information to obtain the first asset information.

[0034] In step 120, based on querying a register in a central processing unit, second asset information of the plurality of PCIE devices is obtained from the register.

[0035] The BMC can obtain the asset information of the PCIe device without relying on the BIOS. The BMC obtains the second asset information based on querying the register in the CPU.

[0036] Specifically, in actual applications, there is a stable way to decouple the BMC from the BIOS asset information. The BMC can directly obtain device information from this storage space without relying on BIOS push. In a more advanced implementation, the BMC can even directly query the relevant registers in the CPU by sending a raw package command to obtain the asset information of the PCIe device. This method does not require the participation of the BIOS and is completely completed by the BMC independently.

[0037] Optionally, obtaining the second asset information may be as follows: Figure 3 The schematic diagram of the process of obtaining the second asset information provided by the present invention is shown. During the startup of the target server, the BMC will also perform initialization loading and self-testing. After the self-testing and loading are completed, the PCIE bus can be accessed through the PCIE protocol, and the PCIE device can be directly connected to the PCIE bus interface for communication, and the asset information of the PCIE device can be read using a query command. The BMC generates the second asset information based on parsing the asset information of the read PCIE device. Among them, the read asset information can also be stored in a fixed area through parsing.

[0038] In step 130, the first asset information is compared with the second asset information, the asset information of each PCIE device is verified, and based on the verification result, the asset information of each PCIE device is classified and stored.

[0039] Optionally, the comparison between the first asset information and the second asset information can be quickly implemented based on the message digest.

[0040] The comparison process of the first asset information and the second asset information based on the message digest algorithm mainly relies on the characteristics of the message digest algorithm, that is, for the same input data, regardless of its size, the same fixed-length digest (or hash value) will be generated, and this generation process is irreversible, that is, the original data cannot be restored from the digest.

[0041] The first asset information is calculated using a selected message digest algorithm (such as SHA-256) to obtain its digest value. Similarly, the second asset information is calculated using the same algorithm to obtain its digest value.

[0042] The summary value of the first asset information is compared with the summary value of the second asset information. If the two summary values ​​are exactly the same, it can be considered that the first asset information and the second asset information are consistent in content. If the two summary values ​​are different, it can be determined that there is a difference in content between the first asset information and the second asset information.

[0043] It can be understood that the first asset information and the second asset information obtained by BMC through two channels can be compared based on some pre-set rules to maximize the correctness of asset information identification, and uncertain information can be recorded as a log as a basis for debug analysis to resolve potential risks in the server.

[0044] Specifically, for each PCIE device, the first asset information and the second asset information of the PCIE device are obtained based on two different channels. Based on the comparison of the first asset information and the second asset information of the PCIE device, the asset information verification process of the PCIE device can be implemented.

[0045] For multiple PCIE devices in the target server, determine whether the asset information of each PCIE device has passed the verification. The PCIE devices that have passed the verification can be stored in storage space A, and the asset information of the PCIE devices that have not passed the verification can be stored in storage space B, so as to implement the classified storage process of the asset information of each PCIE device.

[0046] The asset information verification method provided by the present invention obtains the first asset information and the second asset information of multiple PCIE devices in the target server based on two channels of BIOS and central processing unit, and verifies based on the asset information obtained from the two channels, thereby realizing the confirmation process of the asset information of each PCIE device, improving the accuracy of obtaining the asset information of the PCIE device, and ensuring the stability of the operation of the target server to the greatest extent.

[0047] In one embodiment, before obtaining the first asset information of multiple PCIE devices in the target server from the shared memory space of the target server, it also includes: sending a data acquisition message to the BIOS, so that after the BIOS receives the data acquisition message, it scans the devices on the PCIE bus of the target server, determines the multiple PCIE devices, and based on accessing the configuration space of each PCIE device, extracts the first asset information from the configuration space, and stores the extracted first asset information in the shared memory space.

[0048] Specifically, BMC can rely on BIOS to obtain the asset information of PCIE devices. Before obtaining the asset information, the PCIE device needs to be identified. The identification process of the PCIE device can be as follows: Figure 4 The PCIE device identification process provided by the present invention is shown in the schematic diagram. The target server is powered on, the system starts to start, and it is determined whether the model of the target server is a composite model, a computer model or a storage model. The BIOS of the target server is loaded into the memory as the first software component in the startup process. The BIOS starts to initialize the PCIe bus and scans the devices on the PCIe bus. The scanning process involves traversing each slot on the bus to detect whether there is a PCIe device connected. For each detected PCIe device, the BIOS can read its configuration space (Configuration Space). The configuration space contains key data such as the device's identification information, function code, and resource requirements. The BIOS parses the data read from the configuration space and extracts the first asset information of the PCIE device. Among them, the first asset information includes the device's manufacturer ID, device ID, class code, subclass code, programming interface, etc. The BIOS saves the parsed first asset information to a shared memory space, which can be a device such as a memory or a hard disk. The BMC can read the first asset information in the shared memory space using a general command.

[0049] Optionally, information can be obtained according to different common paths of PCIE devices, and the information obtained from different paths can be compared for consistency. The information can be classified and prioritized according to the type of PCIE device information, and loaded in order of priority. For example, in general, the type of device must be identified first, such as a network card, RAID card, SAS card, and onboard RAID. The device type can be placed in a category of priority identification and judgment, and the priority can be set in front; SN and PN can be placed in one category as a secondary priority, and the division rules can be customized according to the business scenarios of server manufacturers or application manufacturers.

[0050] In one embodiment, the first asset information is compared with the second asset information to verify the asset information of each PCIE device, including: comparing the first asset information with the second asset information, determining multiple first target devices and multiple second target devices from the multiple PCIE devices to verify the asset information of each PCIE device; the first target device is a device whose first asset information is the same as the second asset information; the second target device is a device whose first asset information is different from the second asset information.

[0051] Among them, after comparing the first asset information with the second asset information and determining multiple first target devices and multiple second target devices from the multiple PCIE devices, it also includes: executing a secondary verification process with a preset number of verifications for each second target device, and determining a third target device and a fourth target device from the second target devices based on the secondary verification process with the preset number of verifications; the secondary verification process includes: re-acquiring the first asset information of each second target device and re-acquiring the second asset information of each second target device, and comparing the re-acquired first asset information and the re-acquired second asset information; the third target device is a device determined from the multiple second target devices in the secondary verification process with a preset number of verifications and having the same comparison results; the fourth target device is a device determined from the multiple second target devices in the secondary verification process with a preset number of verifications and having different comparison results each time.

[0052] For each PCIE device, the first asset information of the PCIE device is compared with the second asset information of the PCIE device to determine whether they are the same. If the first asset information of the PCIE device is the same as the second asset information of the PCIE device, the PCIE device is classified as a first target device; if the first asset information of the PCIE device is different from the second asset information of the PCIE device, the PCIE device is classified as a second target device.

[0053] The multiple PCIE devices in the target server are verified respectively, and multiple first target devices and multiple second target devices are determined from the multiple PCIE devices.

[0054] It is understandable that the determination of the second target device is based on only one comparison result. Due to the high efficiency and fast acquisition speed of data in the PCIE channel, there may be a situation where data is acquired inaccurately at one time.

[0055] Therefore, multiple re-verification processes can be implemented based on a secondary verification process with a preset number of verification times.

[0056] Specifically, based on multiple re-verification processes, a third target device and a fourth target device are determined from multiple second target devices. The third target device is a device whose two asset information obtained again during the multiple re-verification processes are identical; the fourth target device is a device whose two asset information obtained multiple times during the multiple re-verification processes are different.

[0057] Optionally, the specific verification process can be as follows Figure 5 As shown in the schematic diagram of the verification process provided by the present invention, the asset information of a certain PCIE device is specifically divided into A1, A2, and A3 according to the priority. A preset verification number N is set, and the initial value is 0. Then, the information of A1 read out by different paths is compared. It is assumed that the data read out by mode 1 based on BIOS is A1-1, and the data read out by mode 2 based on the register of the central processing unit is A1-2, and the data read out by the two modes are compared.

[0058] If the read data is the same, the data will be stored in storage space B. If it is different, it will return to the starting point and re-scan and read, and perform the second polling verification. The number of verifications can be customized according to user needs. Taking the preset number of verifications as ten times as an example, the parameter N will be increased by one each time. If it is still inconsistent for the tenth time, the data will be stored in storage space D. If the data obtained is consistent at any time, the data will be saved in storage space C.

[0059] After multiple polling comparisons and verifications of A1 information, information A2 is obtained and compared. It should be noted that for inconsistent information obtained from A1 information, inconsistent information of A1 block will be added when obtaining and scanning A2 block, which will increase the query volume of inconsistent information in A1, and increase the possibility of obtaining consistent information of PCIE device. Some faults of PCIE device may be repaired in continuous polling, and relatively low-level probabilistic errors will be fault-tolerant. A3 information is consistent with the scanning, acquisition and verification of previous A2 information.

[0060] Finally, according to the continuous polling and verification, the information may be divided into three parts. The information that passes the first verification is stored in storage space B, the information that is consistent with multiple verifications is placed in storage space C, and the inconsistent information is placed in storage space D. Because the use of the target server should also have a certain fault tolerance function, the information in space B and C can be transmitted to the upper-level software for direct display. However, if the information in space C is inconsistent, the log should be saved in the black box log. In case of subsequent risks, debugging can be performed by querying the black box log. The information in space D is uploaded to the upper-level software for display with the information closest to the display rules, and it should be recorded in the startup log to facilitate debugging and troubleshooting.

[0061] In one embodiment, based on the verification results, the asset information of each PCIE device is classified and stored, including: after determining the first target device, the third target device and the fourth target device, the asset information of the first target device, the asset information of the third target device and the asset information of the fourth target device are stored in different storage spaces.

[0062] Among them, after the asset information of the first target device, the asset information of the third target device and the asset information of the fourth target device are stored in different storage spaces, it also includes: based on the first asset information of the third target device and the second asset information of the third target device, generating comparison log information of the third target device, and storing the comparison log information in the black box log.

[0063] The asset information of the first target device, the asset information of the third target device, and the asset information of the fourth target device are classified and stored to facilitate the subsequent retrieval and analysis process.

[0064] For example, the asset information of the first target device that passed the first verification is stored in storage space B, the asset information of the third target device that has been verified to be consistent for multiple times is placed in storage space C, and the inconsistent asset information of the fourth target device is placed in storage space D. Because the use of the target server should also have a certain fault tolerance function, the information in spaces B and C can be transmitted to the upper-level software for direct display, but the information in space C has been inconsistent. Based on the first asset information of the third target device and the second asset information of the third target device, a comparison log information is generated and saved in a black box log. In case of subsequent risks, debugging can be performed by querying the black box log. The information in space D is uploaded to the upper-level software for display with the information closest to the display rules, and it must be recorded in the startup log to facilitate debugging and troubleshooting.

[0065] Among them, black box logs usually refer to log records used to help technicians troubleshoot and diagnose when a system or device fails. This type of log record usually contains key information, error codes, abnormal events, etc. during the operation of the system, but does not directly display the internal implementation details of the system, hence the name "black box".

[0066] In one embodiment, the asset information of the PCIE device includes one or more of the manufacturer ID, device ID, device class code, device subclass code, and programming interface of the device.

[0067] Among them, the manufacturer ID is an identification code representing the patent owner (technology manufacturer) of the invention device.

[0068] The device ID is a code that identifies the device itself. This ID mainly distinguishes different models of the same type of device.

[0069] The device class code is the PCI Express (PCIe) Class Code, which is an identifier used to classify different device types in PCI and PCIExpress devices.

[0070] The device subclass code corresponds to the Subclass part of the device class code and is used to further refine the specific purpose or type of the device under the basic category.

[0071] The device programming interface provides additional information about how the device can be programmed or its interface characteristics.

[0072] The asset information verification device provided by the present invention is described below. The asset information verification device described below and the asset information verification method described above can be referenced to each other.
