Background

In a complete computer system platform, a processor unit, a storage unit, a PCIe (Peripheral Component Interconnect express) controller configuration unit, and various external application interface devices are included.

PCIe devices connected to the main control unit are sequentially scanned by a root node during a system startup process, but when signal quality in the computer system is poor, an enumeration failure may occur, for example, a node of the PCIe device may not be found, or an address space exception occurs when accessing the pci domain (for example, a write operation performed on the bar space may fail to affect a corresponding service); at this time, in order to ensure the normal use of the computer system, the PCIe register can be dynamically modified by switching a remote mode or a local mode through a developed PCIe register configuration tool, and then a SetPCie function command is called, so that the register configuration table acts on a PCIe controller chip through a BUS, and the aim of dynamically adjusting the PCIe register is fulfilled.

The existing PCIe adjusting mode generally adopts a register configuration tool which is compiled in advance, and reads, configures and other operations on relevant registers through a bootstrap program in the starting process of equipment, on one hand, the configuration mode can not visually observe the specific execution process of the configuration operation, and can only judge the configuration result through the running result of a computer system after the configuration is finished, so that the timely calibration action of visually operating a register configuration interface to store or take effect the test result can not be realized, the operation of the configuration process is complex, and the configuration efficiency is reduced; on the other hand, the method is not suitable for different computer systems, and is lack of flexibility, when the computer system is not suitable for the content of a preset register configuration tool, the register configuration command cannot be automatically executed (the instruction information is not a tool), and the configuration efficiency is also reduced.

In this embodiment, a parameter configuration method is provided, and fig. 2 is a flowchart according to an embodiment of the present invention, where the method is applied in a computer system provided with a PCIe control device of a high-speed serial computer expansion bus, and as shown in fig. 2, the flowchart includes the following steps:

step S202, a PCIe control device receives a configuration instruction from a visualization tool which is in communication connection with the PCIe control device, wherein the configuration instruction comprises identification information of a target node to be adjusted in the PCIe control device and a first target value to which a target parameter is to be adjusted;

in this embodiment, the configuration instruction is an instruction generated by the visualization tool after determining, based on the received adjustment instruction, the identification information of the target node to be adjusted and the first target value to which the target parameter is to be adjusted, which are included in the PCIe control device, and the PCIe control device receives the configuration instruction from the visualization tool, so that the parameter adjustment process of the PCIe control device can be displayed by the visualization tool, thereby facilitating adjustment of parameters in the computer system, and also facilitating prediction of an adjusted result.

The visualization tool may be a User Interface (UI) tool, a display screen connected through the UI tool, or other visualization equipment or devices; the display screen may be a touch screen or a display screen connected with an input device (such as a keyboard); the identification information can be a data label, an identification code, or other types of data or identifications capable of identifying the target node; the configuration instruction comprises the identification information of the target node and the first target value, so that the PCIe control device can quickly adjust the target node and the target parameter according to the configuration instruction after acquiring the configuration instruction, thereby improving the adjustment efficiency of the target node and the target parameter.

After receiving the adjustment instruction, the visualization tool firstly identifies the adjustment instruction so as to determine that the configuration instruction comprises the identification information of the target node and the first target value; and then determining a target node to be adjusted and a first target value to which the target parameter is to be adjusted according to the adjustment instruction, generating a configuration instruction, and sending the configuration instruction to the PCIe control equipment.

It should be noted that the manner of sending the configuration instruction to the PCIe control device by the visualization tool may be through wired transmission, or through wireless communication transmission, or through interface transmission.

Step S204, the PCIe control equipment analyzes the configuration instruction to obtain the identification information and the first target value;

in this embodiment, the PCIe control device parses the configuration instruction, so as to convert the identification information and the first target value into a data format that can be recognized by the PCIe control device, so that the PCIe control device can modify and adjust the corresponding target node and the parameter.

In step S206, the PCIe control device adjusts the value of the target parameter of the target node indicated by the identification information to the first target value.

In this embodiment, the target parameter of the target node is adjusted to the first target value to adapt the computer system to actual requirements, so that the computer system can perform good operation under different usage environments.

Through the steps, the visual tool can visually display the target parameter adjusting process of the target node, so that the adjusting result can be pre-judged according to the adjusting process, the adjusting result can be determined without restarting a computer system, the parameter configuration process is simplified, the problem of low parameter configuration efficiency in the related technology is solved, and the parameter configuration efficiency is improved.

In an optional embodiment, adjusting, at the PCIe control device, the value of the target parameter of the target node indicated by the identification information to the first target value includes:

step S2062, the PCIe control equipment acquires first signal quality information in the computer system where the PCIe control equipment is located, wherein the first signal quality information is used for indicating the signal transmission quality in the computer system;

in step S2064, in a case where it is determined that the first signal quality information does not meet the preset condition, the PCIe control device adjusts the value of the target parameter of the target node indicated by the identification information to the first target value.

In this embodiment, the adjustment of the target parameter of the target node according to the first signal quality information in the computer system is to adjust the signal transmission quality in the computer system by adjusting the target parameter of the target node, so as to improve the internal operating efficiency in the computer system.

The first signal quality information includes (but is not limited to) information such as a rate, a data amount, and a data transmission phase of signal transmission in the computer system, and the first signal quality information may be obtained by detecting a designated node through a signal detection module, or by detecting all nodes through the signal detection module, and then determining according to an average value of detection results, or by other methods; the preset condition may (but is not limited to) be set according to an index of a communication protocol, or may be set according to an actual use requirement, or may be determined according to an actual operation condition of the device (such as power consumption, limited power, age, and the like).

For example, when it is detected that the first signal quality information is lower than the signal quality required by the communication protocol, in order to ensure the normal operation of the computer system, the target parameter of the target node is adjusted to the first target value, so that the signal transmission quality of the computer system at the target node meets the requirement, and the signal transmission quality inside the computer system is improved.

The device for detecting the signal quality inside the computer system may be a signal detection module disposed inside the computer system, an external signal detection tool, or other devices having a signal detection function.

in step S2068, when the second signal quality information does not meet the preset condition, the PCIe control device sends a prompt message to the visualization tool, where the prompt message is used to prompt that the second signal quality information does not meet the preset condition.

In this embodiment, after the target parameter of the target node is adjusted to the first target value, the signal transmission quality in the computer system may still not meet the preset condition, and therefore, the target node in the computer system needs to be continuously adjusted; therefore, the adjusted second signal quality information needs to be acquired to determine whether the adjusted internal signal transmission quality of the computer system meets the preset condition, so that the target node can be continuously adjusted under the condition that the adjusted internal signal transmission quality of the computer system does not meet the preset condition, and the signal transmission quality in the computer system meets the preset condition.

And under the condition that the preset condition is determined not to be met, the prompt message is sent to the visualization tool, so that the user can visually know the adjustment result through the visualization tool, and then the user can further adjust the target node according to the adjustment result without adjusting the target node after the computer system is restarted, and the adjustment efficiency is improved.

The second signal quality information also includes (but is not limited to) information such as a rate, a data amount, and a data transmission phase of signal transmission in the computer system, and the second signal quality information may be obtained by detecting a designated node through a signal detection module, or by detecting all nodes through the signal detection module, and then determining according to an average value of detection results, or by other methods; the prompt message includes (but is not limited to) text message, sound message, graphics, etc. for indicating that the second signal quality information does not meet the preset condition, wherein the text message may be text message highlighting the second signal quality information that does not meet the preset condition with different colors, or may be a text of "signal quality is not satisfactory", or may be text message in other forms.

In an optional embodiment, after the PCIe control device obtains the value of the target parameter and adjusts the value to the first target value, the method further includes, after obtaining the second signal quality information in the computer system where the PCIe control device is located:

in step S20610, the PCIe control device stores the first target value in the target storage area when the second signal quality information meets the preset condition.

The target storage area may be a storage area located inside the computer system, may also be an external storage device connected to the computer system, such as a flash, a removable hard disk, or other storage devices or apparatuses, such as a cloud storage, communicatively connected to the computer system.

step S20612, in the case where it is determined that the computer system where the PCIe control device is located is restarted, the PCIe control device calls the first target value from the storage area;

in step S20614, the PCIe control device controls the target node to operate in a manner that the value of the target parameter is the first target value.

In this embodiment, after the computer system is restarted, the first target value is directly called from the target storage area, and the target parameter of the target node does not need to be readjusted, so that the operation efficiency of the adjustment device is saved.

In an alternative embodiment, the present invention further provides an instruction generating method, which is applied in a visualization tool connected to a computer system including a PCIe control device of a high-speed serial computer expansion bus, as shown in fig. 3, and the method includes:
