Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The following explains the terms involved in the present invention:
PCI: peripheral Component Interconnect, Peripheral Component Interconnect standard;
PCI equipment: refers to a device connected to a computing device bus conforming to the PCI bus standard protocol, and is generally a device inserted into a PCI slot;
VID: vendor Identification;
PID: product Identification, Product Identification;
lookup table (Ids lookup table, PCI lookup table): the user can obtain the information corresponding to the device by inquiring a lookup table of a file which is provided by a PCI official and contains VID, PID and corresponding specific information, and the lookup table is stored in a PCI.
Currently, in the conventional device information processing scheme, if a PCI device is not found in the lookup table, the information of the PCI device is discarded. Fig. 1 shows a flowchart of a device information processing method according to the related art. As shown in fig. 1, a plurality of PCI devices (three PCI devices are exemplarily shown in the figure) exist in one computing device, the VID and PID of each PCI device in the plurality of PCI devices are collected through a bus of the computing device, the collected VID and PID are queried one by one in a lookup table, and if information corresponding to the VID and PID is queried, the queried device type, vendor information and product model information are output; if the information corresponding to the VID and the PID is not inquired, the VID and the PID are directly identified as uncertain equipment types and are abandoned.
In the conventional scheme, a situation that information corresponding to VID and PID of a device cannot be queried may occur in some cases, for example, in an actual use process, if a non-standard PCI device is used, or a lookup table stored in a computing device is not updated to a latest version, corresponding information cannot be queried, so that some PCI devices are identified as uncertain device types, and information is discarded. In some cases, the information search may not be complete, for example, the vendor information and the product type corresponding to the VID and the PID are found, but the specific product model is not queried. The existing scheme selectively discards information of product models, which may cause problems in recording information recorded by the device information, for example, detailed information of the PCI device corresponding to the bus address cannot be known, or recorded information is duplicated, or even there is no corresponding hardware information. For example, if there is a non-standard device, only the name and model of the non-standard device are recorded in the system, and a plurality of identical devices are inserted into the computing device, the recorded information will be duplicated. The problem generated by the existing scheme can cause the stored hardware information not to be consistent with the information of the real PCI equipment, thereby further causing errors when the PCI hardware information is identified in the process of system authorization management or equipment verification.
Aiming at the problems in the prior art, the invention provides an equipment information processing method. The following describes the device information processing method of this embodiment in detail.
FIG. 2 shows a flow diagram of a device information processing method 200 according to one embodiment of the invention. As shown in fig. 2, the device information processing method 200 starts at step S210. In step S210, device information of the device connected to the bus is acquired, and the acquired device information is stored as current device information in the device information storage module.
The device information includes Vendor Identification (VID), Product Identification (PID), device identification, and bus address, among others. The device identification of the devices connected to the bus is assigned a device number to distinguish the different devices, for example, a PCI device connected to the bus includes two network cards with different device identifications, such as 001,002, to distinguish the devices. The PCI equipment is connected with the bus through a slot on the bus, and the address corresponding to the bus slot connected with the PCI equipment is the bus address of the equipment.
The device information may include auxiliary information, which is sub-information of the product identifier in the PCI protocol specification, in addition to the above information. If the VENDOR ID and the DEVICE ID cannot completely cover the PCI DEVICE, the spare (spare vector ID and spare DEVICE ID) is added as the auxiliary ID of the DEVICE according to the PCI protocol standard, and thus, a PCI DEVICE does not necessarily have auxiliary information. Fig. 3 shows a flow diagram of a device information processing method 200 according to one embodiment of the invention. The various PCI devices shown in fig. 3 contain VIDs, PIDs and bus addresses, and may also contain auxiliary information depending on the device conditions.
Through this step, the acquired device information is stored as current device information in the device information storage module. Through the same steps, the current device information of the device can be acquired at different moments, and when the latest current device information is acquired, the current device information acquired before can be used as historical device information. Alternatively, the history device information may be stored in an overriding manner, for example, the history device information (id: 001) and the current device information (id: 002) are currently stored, and the latest current device information (id: 003) is stored, so that the latest information overrides the original information, the current device information with id 002 is used as the history device information, and the current device information with id 003 is used as the latest current device information. Optionally, all or part of the acquired historical device information may be stored, and when the historical device information is compared with the current device information in the subsequent process, the user may select the compared object by himself.
Subsequently, in step S220, comparing the current device information with the historical device information stored in the device information storage module to determine whether the device is changed;
according to an embodiment of the present invention, if the historical device information is the same as the current device information, it is determined that the device has not been changed; and if the historical equipment information is different from the current equipment information, determining that the equipment is changed.
Specifically, if some device information exists in the historical device information but does not exist in the current device information, it may be determined that the device corresponding to the device information is removed; if some device information does not exist in the historical device information but exists in the current device information, it can be determined that the device corresponding to the device information is added, that is, the device is a newly added device; if the bus address in a piece of device information is different between the history device information and the current device information, but the rest information in the piece of device information is the same, it can be determined that the device location corresponding to the piece of device information has changed, that is, the device has changed in the location connected to the bus.
According to an embodiment, if the slot position of the PCI device in the computing device is changed but the device is not changed, it can be known by looking up differences between VIDs and PIDs in the historical device information and the current device information and corresponding bus addresses, and if all the device information such as VIDs and PIDs previously recorded in the historical device information can be found, only the device bus position is changed but the device still exists, it can be confirmed that the slot position (i.e. the bus position) of the PCI device is changed.
If the bus address of the PCI device in the computing device still exists but one or more of VID, PID and auxiliary information of the PCI device are different, the PCI device can be judged to be replaced. The device label is used to number the device, and for example, the VID information of the PCI device recorded as number 1 is different from the VID information in the history device record, and the bus address of the device is the same, so that it can be determined that the device has been changed.
According to an embodiment, since some PCI devices further include auxiliary information, when the PCI device changes, the comparison and verification are performed, if the PCI device includes the auxiliary information, the auxiliary information needs to be compared. If the PCI equipment is not changed, the auxiliary information of the PCI equipment is not changed, so that when the auxiliary information is found to be changed during comparison, the equipment can be determined to be changed. Since the same VID and PID of the devices may also appear, but the same type of devices of the same manufacturer and different models of subds may also appear, the same type of devices of the same manufacturer and different models of subds may be recognized by comparing the auxiliary information.
According to the embodiment of the invention, the result of determining whether to change (namely, the result of comparison) is displayed and output.
For example, in the authorization of the operating system, whether the host is changed or not may be determined, and if the host is not the same host or the host is changed, the authorization of the operating system is not performed, and other processing schemes are adopted.
Subsequently, in step S230, the current device information is queried in a lookup table, and detailed information corresponding to the device information is generated, where the lookup table includes the manufacturer identifier and the product identifier, and the detailed information corresponding thereto.
According to the embodiment of the present invention, as shown in fig. 3, device information is first recorded to the PCI devices to generate current device information, where the current device information includes VID, PID, bus address, and device identifier corresponding to each PCI device, and may also include auxiliary information of the PCI devices. And then, searching the generated current equipment information in a lookup table, and displaying and outputting the current equipment information and the searched detailed information, wherein the detailed information comprises manufacturer information corresponding to the manufacturer identification and a product type corresponding to the product identification. The information of the equipment is recorded and then searched, so that the problem that the information which is not searched is abandoned is solved.
It should be noted that although the lookup table is usually updated in real time, there may be situations where the lookup table is incomplete in some situations, for example, when the host of the computing device is offline or updated to a newer system, which may cause ids of the lookup table to lag behind the officially registered version that is up to date with the authority, a situation may occur where the new device cannot find the corresponding VID and/or PID. In addition, some manufacturers do not use auxiliary information such as VID, PID, and subid according to the specification, and if a designed temporary device or a non-standard PCI device does not receive a usable ID number through an official, the PCI lookup table cannot be queried due to device information being wrongly written. With the existing scheme, the situation that the device information is directly discarded can occur. By adopting the equipment information processing method, even if the above conditions occur, such as the conditions of incomplete non-standard PCI equipment or an incomplete PCI lookup table, and the equipment information display output module judges the abnormal condition, VID, PID and bus address information corresponding to the incomplete equipment information are directly output and identified so as to timely feed back the abnormal condition, and a user can inquire all information of abnormal equipment, so that the problem of abandoning the equipment information or repeatedly displaying the information can not occur.
By displaying and outputting the current device information and the searched detailed information, the user can more intuitively obtain the information of the device. Because the information such as VID and PID is usually serial number used for identification, the user can not know the device information such as the type of the device and the like only through VID and PID, the detailed information such as what device, model, brand and the like can be visually seen by the user through the lookup table, the displayed information also comprises the content included in the current device information, and the user can acquire the complete information about the device through the device information display output module.

The device information processing system 400 shown in fig. 4 includes a device information obtaining module 410, a device information storing module 420, a device information comparing module 430, and a device information querying module 440.

The device information storage module 420 may store the acquired device information as current device information.
The device information comparison module 430 may compare the current device information with the historical device information included in the device information storage module and determine whether the device is changed.

In addition, the device information processing system 400 may further include a device information display output module 450, configured to display and output a result of determining whether to change (i.e., a result of the comparison); displaying and outputting the current equipment information and the searched detailed information; and after the abnormity is judged, VID, PID and bus address information corresponding to the incomplete equipment information are directly output and identified so as to feed back the abnormal condition in time.
