Moreover, the terms "comprises" and "comprising," as well as any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements does not include other steps or elements inherent in the present invention.
In view of the above objects, a first aspect of an embodiment of the present invention provides an embodiment of a method for checking a configuration of a BMC display chip. Fig. 1 is a schematic diagram illustrating an embodiment of a method for checking a configuration of a BMC display chip according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
step S10, initializing a register of a display chip by a BIOS (basic input output System) to obtain first register information to be self-checked, storing the first register information to a JSON (Java Server object notation) file, and transmitting the JSON file to a BMC (baseboard management controller), wherein the JSON file contains related information for register classification according to a preset strategy;

and S50, traversing the list, comparing the data in the list with the second register information, and correspondingly processing the register values of the registers of different types of the display chip according to the comparison result.
The embodiment of the invention ensures that the necessary register configuration of the display chip is normal and the picture is displayed normally by checking the configuration of the BIOS on the display chip; the default configuration of the register of the display chip is stored by the BMC, and the register of the display chip can be recovered to be normal when the register of the display chip is detected to be abnormal, so that the system stability is improved by correcting the configuration error of the display chip in time; by implementing the embodiment in the server starting stage, the display related faults can be found as early as possible, the probability of display errors is reduced, and the influence on user experience caused by abnormal operation of the display chip due to configuration problems is avoided.
The embodiment of the invention can configure the data of the relevant register through the default configuration file to adapt to different products and chips.
In some embodiments, the first register information includes register information of the PCIE configuration section and the display-related configuration section.
In some embodiments, classifying the registers according to a predetermined policy includes: the method comprises the steps of dividing the register into a fixed register class, a floating register class and a variable register class according to values of registers, wherein register values in the fixed register class are in a fixed invariable state, register values in the floating register class are in a variable state in a preset value range, and register values in the variable register class are in a variable state.
In the above embodiment, register information that needs to be self-checked may be transmitted between the BMC (Baseboard Management Controller) and the BIOS (Basic Input Output System) through a JSON (JavaScript Object notification, javaScript Object Notation, a lightweight data exchange format) file. These registers can be divided into two categories by function:
1) A PCIE configuration section. The part mainly comprises the first 64 bytes of information of a PCIE configuration space and the configuration of a base address register. After the information of the configuration space is initialized by the BIOS, the information is stored in the JSON file. The PCIE configuration space is a series of regularly arranged registers defined by a PCIE (peripheral component interconnect express, a high speed serial computer extended bus standard), and usually includes 256 bytes of data, which includes vendor id, device id, and base address register and other information related to the PCIE device.
2) The relevant configuration section is displayed. This section contains the necessary register settings for the display chip including PLL, MODE, FB ADDRESS, FB WIDTH, display WIDTH, height, bit depth, refresh rate, horizontal scan time, vertical scan time, refresh time, etc. Wherein the horizontal scan time, vertical scan time, and refresh time comprise a series of registers needed to calculate these times.
The BMC obtains the default register address and register data and the register address and data configured by the BIOS by parsing the JSON file, which is defined as follows by way of example:
Figure BDA0003894898360000071
Figure BDA0003894898360000081
Figure BDA0003894898360000091
the JSON file is simple in structure and easy to understand. The time of file generation, namely pci _ config and video _ config, is contained in the file system. In a JSON file, each set of data contains three parts: reg, data and description. Where reg indicates the register address and data is the register value.
In pci _ config, the data contains 64 bytes of value, and the BMC parses these binary data according to the pci configuration space format.
The video _ config comprises a plurality of register data consisting of reg and data, and the registers are divided into three types according to the value strategies: fixed register class, floating register class, and variable register class. The register value in the fixed register class is fixed, for example, the address of FB (frame buffer, which can be regarded as a memory area containing data to be displayed on a display) does not change in a system, and is a fixed value. In the floating register class, the data of the register is variable in a certain value range, for example, the screen resolution may have a value range of [1920x1080], [1024x768], [800x600], and the like, and the screen refresh rate may have a value range of [60hz ], [90hz ], but the value range is definite and can only take these values. In the variable register class, the value of the register is changed, and different values can be obtained according to different scenes and different parameters, for example, a position register of a hardware mouse can change along with different positions of the mouse.
All the register data can use big endian or little endian, and only the consistency of the BIOS and the BMC is required to be ensured. After the BIOS initializes the VIDEO (display module), the data is written into a predetermined JSON file according to the above format, and is read by the BMC in a self-test program.
In some embodiments, reading, by the BMC, the self-check flag to confirm whether the transfer of the JSON file is completed comprises: reading the self-checking mark by the BMC, and confirming whether the self-checking mark is set to a first preset value by the BIOS within preset time; and responding to the fact that the self-checking mark is set to be a first preset numerical value within preset time, and confirming that the JSON file is transmitted completely.
In some embodiments, the method further comprises: and determining that the self-checking fails in response to the self-checking flag not being set to the first predetermined value within the preset time.
In some embodiments, the method further comprises: in response to completion of the register value processing, the BMC sets the self-test flag to a second predetermined value.
In some embodiments, the performing the corresponding register value processing on the different types of registers of the display chip according to the comparison result comprises: in response to that the first register of the display chip belongs to the fixed register class and the corresponding comparison results are inconsistent, setting the value of the first register as the corresponding register value in the second register information; responding to the fact that a second register of the display chip belongs to the floating register class and corresponding comparison results are inconsistent, resetting the value of the second register according to an actual scene, wherein the value of the second register is within a preset value range; and resetting the value of the third register according to the actual scene in response to that the third register of the display chip belongs to the variable register class and the corresponding comparison results are inconsistent.
Fig. 2 is a schematic diagram of a self-test flow of the configuration of the BMC display chip according to an embodiment of the present invention. As shown in fig. 2, the BMC self-test procedure first reads a default configuration file (the configuration file format is similar to the JSON file format and includes a comprehensive register list), and initializes default configurations of local registers, which may be derived from the following points: 1. a chip data manual; 2. product characteristics; 3. generating a fixed algorithm; 4. and obtaining by other methods. During the initialization process of the register value, the registers are grouped according to the above strategy.
After initialization is complete, the BMC self-test routine waits until self _ flag (i.e., the self-test flag) is set to 1 (i.e., the first predetermined value) by the BIOS. If the value is not set to 1 within the specified time, the self-test fails and the process ends.
After self _ flag is set to 1, the BMC starts parsing the JSON file and stores the JSON file in the list according to a fixed format, and then traverses the list using a traversal algorithm, compares the initialized default value with the register value in the list, and performs corresponding processing according to different register grouping policies. The specific idea of the treatment is as follows: for the registers in the fixed register class, if the value set by the BIOS is inconsistent with the value of the default configuration, the value of the default configuration needs to be set; for the registers in the floating register class, if the value set by the BIOS is inconsistent with the default configuration range, resetting the register value according to the corresponding scene and parameters; for the registers in the variable register class, if the values set by the BIOS do not match the default values, the following aspects need to be combined for processing: 1. the meaning of the specific register; 2. a scenario of register association; 3. other parameters associated with the register; 4. other register values associated with the register, such as a hardware mouse position register, are considered valid if the position is within the screen display range.
After all register variables in the list are checked according to the process, the BMC sets self _ flag to 2 (namely, a second preset value), namely, the self-checking is successfully completed; if the self-test fails, self _ flag is set to-1. The value of self flag may provide a reference for developers to locate display problems.
The embodiment solves the problem that the abnormal display picture can not be corrected due to the configuration error of the display chip in the server starting stage, intercepts the configuration problem of the display chip possibly occurring in the server using stage of developers or server managers, improves the user experience and enhances the robustness of the display system. The default configuration file of the display chip can also provide reference for developers and server managers.
