Description

Technical Field

[0001] This invention relates to the field of server technology, and in particular to a method, system, storage medium, and device for checking the configuration of a BMC display chip. Background Technology

[0002] In current server rooms, due to space and heat dissipation limitations, dedicated display devices are typically not configured like those in personal computers. The common practice is to place the display chip within the Baseboard Management Controller (BMC). The BMC then provides the server with the display chip's functionality, and remote viewing via VNC (Virtual Network Console) or KVM (Keyboard Video Mouse) is used to view the server's display. The display chip undergoes initial configuration during BIOS (Basic Input Output System) startup. Since there is no display device, it's impossible to verify the correctness of the BIOS configuration for the display chip. After the BIOS initialization is complete and the host boots up, errors may occur in the server display during KVM or VNC, and the problem may only be discovered when the user or server administrator uses the system, resulting in a poor user experience.

[0003] The existing technical solutions lack checks on the display chip register configuration in the BMC, making it impossible to correct display chip configuration errors that cause display abnormalities during system startup. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method, system, storage medium and device for checking the configuration of the BMC display chip, so as to solve the problem that the prior art lacks the check of the display chip register configuration in the BMC, and cannot correct display chip configuration errors during system startup, which leads to display abnormalities.

[0005] To achieve the above objectives, the present invention provides a method for checking the configuration of a BMC display chip, comprising the following steps:

[0006] The BIOS initializes the display chip's registers, obtains the first register information to be tested, saves it to a JSON file, and transmits the JSON file to the BMC. The JSON file contains information on register classification according to a preset strategy.

[0007] The BMC initializes the default configured registers to obtain the second register information and classifies them according to a preset strategy.

[0008] The BMC reads the self-check flag to confirm whether the JSON file transmission is complete;

[0009] In response to the completion of the transmission, BMC parses the JSON file and saves the parsed data to a list;

[0010] The list is traversed, and the data in it is compared with the information in the second register. Based on the comparison results, the register values ​​of different types of registers of the display chip are processed accordingly.

[0011] In some embodiments, the BMC reads a self-check flag to confirm whether the JSON file transmission is complete, including:

[0012] The BMC reads the self-test flag and confirms whether the self-test flag is set to the first predetermined value by the BIOS within a preset time.

[0013] In response to the self-check flag being set to the first predetermined value within a preset time, the JSON file transfer is confirmed to be complete.

[0014] In some embodiments, the method further includes:

[0015] If the self-test flag is not set to the first predetermined value within a preset time, the self-test is determined to have failed.

[0016] In some embodiments, register classification according to a preset strategy includes:

[0017] Based on the values ​​of each register, they are divided into fixed registers, floating registers, and variable registers. Among them, the register values ​​in the fixed register class are fixed, the register values ​​in the floating register class are variable within a preset range, and the register values ​​in the variable register class are variable.

[0018] In some embodiments, processing the register values ​​of different types of registers in the display chip according to the comparison results includes:

[0019] In response to the fact that the first register of the display chip belongs to the fixed register class and the corresponding comparison result is inconsistent, the value of the first register is set to the corresponding register value in the second register information;

[0020] In response to the fact that the second register of the display chip is a floating register and the corresponding comparison results are inconsistent, the value of the second register is reset according to the actual scenario, and the value of the second register is within the preset value range;

[0021] Since the third register of the display chip is a variable register and the corresponding comparison results are inconsistent, the value of the third register is reset according to the actual scenario.

[0022] In some embodiments, the first register information includes register information for the PCIe configuration section and the display-related configuration section.

[0023] In some embodiments, the method further includes:

[0024] In response to the completion of register value processing, the BMC sets the self-test flag to the second predetermined value.

[0025] In another aspect, the present invention provides a system for checking the configuration of a BMC display chip, comprising:

[0026] The JSON file module is configured to initialize the display chip's registers by the BIOS, obtain the first register information to be tested, save it to a JSON file, and transmit the JSON file to the BMC. The JSON file contains relevant information on register classification according to a preset strategy.

[0027] The classification module is configured to initialize the default-configured registers by the BMC, obtain the second register information, and classify the registers according to a preset strategy.

[0028] The confirmation module is configured to have the BMC read the self-check flag to confirm whether the JSON file transmission is complete.

[0029] The parsing module is configured to parse the JSON file by BMC in response to the completion of the transmission and save the parsed data to a list; and

[0030] The processing module is configured to traverse the list, compare the data in it with the information in the second register, and process the register values ​​of different types of registers of the display chip accordingly based on the comparison results.

[0031] In another aspect, the present invention provides a computer-readable storage medium storing computer program instructions that, when executed by a processor, implement the above-described method.

[0032] In another aspect, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program that, when executed by the processor, performs the above-described method.

[0033] The present invention has at least the following beneficial technical effects:

[0034] This invention checks the BIOS configuration of the display chip to ensure that the necessary registers of the display chip are configured correctly and the screen displays normally. By saving the default configuration of the display chip registers in the BMC, it can restore the display chip registers to normal when abnormalities are detected, thereby improving system stability by correcting display chip configuration errors in a timely manner.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0042] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two different entities or different parameters with the same name. Therefore, "first" and "second" are merely for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as other steps or units inherent in a process, method, system, product, or device that includes a series of steps or units.

[0043] Based on the above objectives, a first aspect of the present invention provides an embodiment of a method for checking the configuration of a BMC display chip. Figure 1 This diagram illustrates an embodiment of the method for checking the configuration of a BMC display chip provided by the present invention. Figure 1 As shown, the embodiments of the present invention include the following steps:

[0044] Step S10: The BIOS initializes the registers of the display chip, obtains the first register information to be tested, saves it to a JSON file, and transmits the JSON file to the BMC. The JSON file contains relevant information on register classification according to a preset strategy.

[0045] Step S20: The BMC initializes the default configured registers to obtain the second register information and classifies them according to a preset strategy.

[0046] Step S30: The BMC reads the self-test flag to confirm whether the JSON file has been successfully transmitted;

[0047] Step S40: In response to the completion of the transmission, the BMC parses the JSON file and saves the parsed data to a list;

[0048] Step S50: Traverse the list and compare the data in it with the information in the second register, and process the register values ​​of different types of registers of the display chip accordingly based on the comparison results.

[0049] This invention verifies the correct configuration of the display chip's registers by checking the BIOS settings, ensuring proper display and screen display. By saving the default configuration of the display chip's registers in the BMC, it can restore the display chip's registers to normal when malfunctions are detected, thereby improving system stability by promptly correcting display chip configuration errors. Implementing this method during server startup allows for early detection of display-related faults, reducing the probability of display errors and preventing user experience issues caused by abnormal display chip operation due to configuration problems.

[0050] The embodiments of the present invention can configure the data of relevant registers through a default configuration file to adapt to different products and chips.

[0051] In some embodiments, the first register information includes register information for the PCIe configuration section and the display-related configuration section.

[0052] In some embodiments, register classification according to a preset strategy includes: dividing registers into fixed register class, floating register class and variable register class according to the value of each register, wherein the register value in the fixed register class is in a fixed state, the register value in the floating register class is in a variable state within a preset value range, and the register value in the variable register class is in a variable state.

[0053] In the above embodiments, the BMC (Baseboard Management Controller) and BIOS (Basic Input Output System) can exchange register information requiring self-test via JSON (JavaScript Object Notation, a lightweight data exchange format) files. These registers can be divided into two categories according to their function:

[0054] 1) PCIe Configuration Section. This section mainly includes the configuration of the first 64 bytes of the PCIe configuration space and the base address register. The configuration space information is initialized by the BIOS and then stored in a JSON file. The PCIe configuration space is a series of registers arranged according to certain rules as defined by the PCIe (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) specification. It typically contains 256 bytes of data, including the vendor ID, device ID, base address register, and other information related to the PCIe device.

[0055] 2) Display-related configuration section. This section contains the settings for the necessary registers of the display chip, including PLL, MODE, FB ADDRESS, FB WIDTH, display width, height, bit depth, refresh rate, horizontal scan time, vertical scan time, and refresh time. The horizontal scan time, vertical scan time, and refresh time include a series of registers required to calculate these times.

[0056] The BMC obtains the default register addresses, register data, and BIOS configuration register addresses and data by parsing JSON files. For example, its format definition is as follows:

[0057]

[0058]

[0059]

[0060] The JSON file has a simple and easy-to-understand structure. It contains three parts: the file generation time, pci_config, and video_config. Each data set in the JSON file contains three parts: reg, data, and description. reg indicates the register address, and data is the register value.

[0061] In pci_config, data will contain a 64-byte value, and BMC will parse this binary data according to the pci configuration space format.

[0062] The `video_config` file contains a series of registers, each consisting of `reg` and `data`. These registers are categorized into three types based on their value assignment: fixed registers, floating registers, and variable registers. Fixed registers have fixed values; for example, the address of the FrameBuffer (which can be viewed as a memory region containing data to be displayed on the screen) remains constant throughout the system. Floating registers have variable values ​​within a certain range. For instance, screen resolutions can range from [1920x1080], [1024x768], to [800x600], and screen refresh rates can range from [60Hz] to [90Hz]. However, the value range is fixed, and only these values ​​can be taken. Variable registers have changing values ​​that vary depending on the scenario and parameters. For example, the position register of a hardware mouse changes depending on the mouse's position.

[0063] All the register data mentioned above can use either big-endian or little-endian, as long as the BIOS and BMC are consistent. After the BIOS completes the VIDEO (display module) initialization, it will write this data to the specified JSON file according to the above format, which will then be read by the BMC during its self-test program.

[0064] In some embodiments, reading the self-test flag by the BMC to confirm whether the JSON file transmission is complete includes: reading the self-test flag by the BMC and confirming whether the self-test flag is set to a first predetermined value by the BIOS within a preset time; and confirming that the JSON file transmission is complete in response to the self-test flag being set to the first predetermined value within the preset time.

[0065] In some embodiments, the method further includes: determining a self-test failure in response to a self-test flag not being set to a first predetermined value within a preset time.

[0066] In some embodiments, the method further includes: in response to the completion of register value processing, the BMC sets a self-test flag to a second predetermined value.

[0067] In some embodiments, processing the register values ​​of different types of registers of the display chip according to the comparison results includes: in response to the first register of the display chip being a fixed register and the corresponding comparison results being inconsistent, setting the value of the first register to the corresponding register value in the second register information; in response to the second register of the display chip being a floating register and the corresponding comparison results being inconsistent, resetting the value of the second register according to the actual scenario, and the value of the second register being within a preset value range; in response to the third register of the display chip being a variable register and the corresponding comparison results being inconsistent, resetting the value of the third register according to the actual scenario.

[0068] Figure 2 This is a schematic diagram of the self-test process for a BMC display chip configuration provided according to an embodiment of the present invention. Figure 2 As shown, the BMC self-test process first reads the default configuration file (the configuration file format is similar to a JSON file format and contains a comprehensive list of registers) and initializes the default configurations of the relevant local registers. These default values ​​may come from the following sources: 1. Chip datasheet; 2. Product features; 3. Fixed algorithm generation; 4. Other methods of acquisition. During the register value initialization process, registers are grouped according to the aforementioned strategy.

[0069] After initialization is complete, the BMC self-test program will wait until self_flag (i.e., the self-test flag) is set to 1 by the BIOS (i.e., the first predetermined value). If it is not set to 1 within the specified time, the self-test fails and the process ends.

[0070] After `self_flag` is set to 1, the BMC begins parsing the JSON file and saving it to a list according to a fixed format. Next, it iterates through the list using an algorithm, comparing the initial default value with the register values ​​in the list, and processing them according to different register grouping strategies. The specific processing logic is as follows: For registers in the fixed register class, if the BIOS setting value is inconsistent with the default configuration value, it needs to be set to the default configuration value; for registers in the floating register class, if the BIOS setting value is inconsistent with the default configuration range, the register value will be reset according to the corresponding scenario and parameters; for registers in the variable register class, if the BIOS setting value does not match the default value, the following aspects need to be considered: 1. The specific meaning of the register; 2. The scenario associated with the register; 3. Other parameters associated with the register; 4. Other register values ​​related to the register, such as the hardware mouse position register, where the value is considered valid if the position is within the screen display range.

[0071] After all register variables in the list have been checked according to the above process, the BMC will set self_flag to 2 (i.e., the second predetermined value), indicating that the self-test has been successfully completed; if the self-test fails, self_flag will be set to -1. The value of self_flag can provide developers with a reference for locating display problems.

[0072] The above embodiments resolve the issue of display chip configuration errors during server startup leading to uncorrectable display anomalies. They also prevent display chip configuration problems that may occur during server usage by developers or server administrators, improving user experience and enhancing the robustness of the display system. The default configuration file for the display chip can also serve as a reference for developers and server administrators.

[0073] A second aspect of the present invention also provides a system for checking the configuration of a BMC display chip. Figure 3 This diagram illustrates an embodiment of the system for checking the configuration of a BMC display chip provided by the present invention. Figure 3As shown, a system for checking the configuration of a BMC display chip includes: a JSON file module 10, configured to initialize the registers of the display chip by the BIOS, obtain the first register information to be self-tested, save it to a JSON file, and transmit the JSON file to the BMC, wherein the JSON file contains relevant information for register classification according to a preset strategy; a classification module 20, configured to initialize the registers of the default configuration by the BMC, obtain the second register information, and classify the registers according to a preset strategy; a confirmation module 30, configured to read the self-test flag by the BMC to confirm whether the JSON file transmission is complete; a parsing module 40, configured to parse the JSON file by the BMC in response to the completion of transmission, and save the parsed data to a list; and a processing module 50, configured to traverse the list, compare the data in it with the second register information, and perform corresponding register value processing on different types of registers of the display chip according to the comparison result.

[0074] The system for checking the BMC display chip configuration in this embodiment of the invention ensures that the necessary registers of the display chip are configured correctly and the screen displays normally by checking the BIOS configuration of the display chip. By saving the default configuration of the display chip registers in the BMC, it can restore the display chip registers to normal when abnormalities are detected, thereby improving system stability by correcting display chip configuration errors in a timely manner. By implementing this embodiment during the server startup phase, display-related faults can be detected as early as possible, reducing the probability of display errors and avoiding the impact on user experience caused by abnormal display chip operation due to configuration problems.
