Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

To facilitate understanding, a description will first be given of how the graphics card initialization operation is currently performed by VBIOS. Fig. 1 is a flow chart of a conventional graphics card initialization operation performed by VBIOS. As shown in fig. 1, the process may include:

S101, acquiring a preset VBIOS file.

The preset VBIOS file includes data required for initializing the graphics card, for example, may include graphics card initialization codes, graphics card parameters and configuration information, display mode and resolution data, graphics card power consumption and fan control data, firmware update and repair data, and the like.

Currently, the preset VBIOS file stores data required by initializing the graphics cards in a form of a sequence table. When the operation of initializing the display card is performed through the preset VBIOS file, the data required by the operation of initializing the display card is obtained by traversing the sequence table.

When the display card performs update iteration, the data stored in the preset VBIOS file needs to be updated (e.g., newly added, deleted, modified, etc.) according to the update iteration condition of the display card. Since the preset VBIOS file currently stores the data in a sequential table manner, it is necessary to manually select the modified data location in the preset VBIOS file. For example, when new data is needed, it is necessary to manually determine the position of the new data in the sequence table of the preset VBIOS file, and determine the offset of the subsequent data in the sequence table according to the size of the new data, so as to newly add the data to the sequence table, instead of simply newly adding the new data after the last item of data in the original sequence table. If the newly added data is directly added after the last item of data in the original sequence table, the problem of operation error and the like may occur when initializing the graphics card through the preset VBIOS file.

S102, analyzing a preset VBIOS file to obtain data required by initializing the display card.

Traversing all data in the VBIOS file according to the sequence of the sequence table in the preset VBIOS file, and extracting necessary data for initializing the display card from the data.

S103, initializing the display card according to the data.

According to the data obtained from the preset VBIOS file, the operating system of the equipment where the display card is located prepares parameters required by initializing the display card. And calling a display card driver or an underlying operating system interface to execute the display card initialization code so as to read the initialization parameters prepared before and apply the initialization parameters to the display card hardware. During the initialization process, the operating system may verify the status of the graphics card and perform the necessary configuration. For example, checking whether the display output is normal, confirming the resolution and refresh rate supported by the graphic card, etc. And after the verification is finished, finishing the initialization operation of the display card.

Therefore, the current VBIOS file mainly stores data in a sequence table manner, so that when the update iteration requirement exists in the current VBIOS file, the data in the VBIOS file needs to be manually processed, for example, the occupied memory size of the data to be modified needs to be manually calculated, and appropriate memory offset is made, so that long time and more manpower are required to be consumed for processing. Therefore, the current VBIOS file has the problems of poor expansibility of a storage mode, low efficiency of storage and access and the like.

In view of this, the present application provides a method for initializing a graphics card, which generates a VBIOS file with an index section and a data section and in a linked list format, and only needs to read the content of the index section during the initialization process of the graphics card, so as to quickly locate the data in the data section corresponding to the index section and obtain the position of the data in the VBIOS file. And when updating the VBIOS file, the updating speed can be improved only by filling the data to be modified into the free space of the data segment and modifying or newly adding the index with the corresponding relation with the data to be modified, thereby improving the expansibility, storage and access efficiency of the VBIOS storage information.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flow chart of a graphics card initializing method according to an embodiment of the present application. As shown in fig. 2, the method may include:

S201, the first electronic device generates a VBIOS file.

The VBIOS file is generated by a VBIOS generating tool, and the VBIOS generating tool may be a driver, program code software, or a medium storing relevant execution code, for example, a usb disk. The first electronic device is a physical device integrated with or installed with the VBIOS generating tool related execution code, for example, an electronic device such as a chip, a micro control unit (Microcontroller Unit, abbreviated as MCU), a computer, and the like.

The VBIOS file includes an index section, a data section. The data segment is used for storing the data of the display card, the data of the display card comprises target data required by initializing the display card, and can also comprise other data irrelevant to initializing the display card, such as data of a display support list, parameters and settings related to performance adjustment of the display card, fault diagnosis and error processing data and the like. The target data may include video memory configuration data, display mode setting data, rendering engine data, clock setting data, power management data, output port setting data, etc. data required to initialize the video card.

The index segment includes at least one index of data mapped to the graphics card. The indexes in the index section can be determined according to the type, the use and the like of the data of the display card, and each index corresponds to the data of a part of the display card. The mapping relation between the index and the data of the display card is used for determining the storage position, the memory occupation condition and the like of the data of the display card corresponding to the index in the VBIOS file. The mapping relationship may, for example, identify at least one item of information such as a memory start position, a memory end position, and a memory occupation of the data of the graphics card corresponding to the index. Through the index and the mapping relation between the index and the data of the display card, the data of the display card corresponding to the index can be analyzed and extracted.

The method for generating the VBIOS file by the first electronic device may refer to the prior art, and the VBIOS file in the present application is only different from the existing VBIOS file in storage format, and the generation manner is similar, and is not repeated herein.

The format of the index may be, for example, as shown in table 1 below:

TABLE 1

Optionally, after the first electronic device generates the VBIOS file, the VBIOS file may be stored in a video memory of a video card in the electronic device to be initialized by the video card, or in a storage medium of the electronic device, so that the electronic device may acquire the VBIOS file when initializing the video card.

S202, the processor of the second electronic device responds to an initialization instruction of the display card, and the generated VBIOS file is obtained from the video memory of the display card.

The second electronic device is an electronic device to be initialized by a display card, for example, may be a device with a display card, such as a computer, a mobile phone, a tablet computer, etc. The initialization instruction of the display card is used for indicating the second electronic device to perform the initialization operation of the display card, and the instruction can be issued by the second electronic device by using a user operating the second electronic device or can be automatically triggered in the starting process of the second electronic device.

The processor of the second electronic device responds to the initialization instruction of the display card, and guides the kernel of the operating system to start through a bootstrap program, and copies the data in the generated VBIOS file to a specific position in the display memory of the display card of the second electronic device by utilizing the bootstrap program, wherein the bootstrap program can be bootloader firmware, pmon firmware, uefi firmware and the like. Optionally, the VBIOS file may be pre-stored in a storage medium of the second electronic device, and when responding to an initialization instruction of a video card, the VBIOS file is copied to a video memory of the video card, so that data in the VBIOS file is copied to a specific location in the video memory of the video card of the second electronic device. Or the VBIOS file is pre-stored in the video memory, and when responding to the video card initialization instruction, the bootstrap program is utilized to copy the data in the VBIOS file to a specific position in the video memory of the video card of the second electronic device.

And after copying the data in the VBIOS file to a specific position in the video memory of the video card of the second electronic device, jumping to an initialization flow of the operating system kernel of the second electronic device. In the initialization process of the kernel of the operating system, the processor of the second electronic device matches the display controller (Display controller, DC) driver, and if the DC driver is successfully matched with the second electronic device, the data in the VBIOS file is obtained from a specific location in the video memory.

Optionally, when the data in the VBIOS file is obtained, the VBIOS file may also be checked to determine whether the VBIOS file is available.

For example, the identifier (such as a name, a number, etc.) of the VBIOS file may be checked, and if the VBIOS file is an available VBIOS file of the display card of the second electronic device, the check passes; if the VBIOS file is not the available VBIOS file of the display card of the second electronic device, checking an error, exiting the DC driver and re-providing correct VBIOS information. Illustratively, the checking is performed by a DC driver, and the DC driver may perform checking according to an identifier in the VBIOS file (for example, may be an identifier of a name, a title, etc. of the VBIOS file stored in the VBIOS file), and if the identifier is the same as a preset identifier, the checking is passed. If the verification fails, the DC drive is stopped, and after a new VBIOS file is stored in the video memory of the video card again, the new VBIOS file is acquired for verification until the verification passes.

S203, the processor acquires a target address of the target data in the VBIOS file according to the target index corresponding to the target data and at least one index.

And the processor traverses the index segment in the VBIOS in the process of executing the initialization operation of the display card, and acquires all indexes included in the index segment. And for target data required in the initialization operation process of the display card, matching the index identical to the target index in the index section in the VBIOS according to the target index corresponding to the target data. If the matching is successful, determining the position or address of the target data in the VBIOS file according to the mapping relation between the target data and the data of the display card stored in the index. The processor extracts the target data according to the position or address of the target data in the VBIOS file, so as to be used for initializing corresponding parameters in the display card according to the target data.

S204, the processor extracts target data from the VBIOS file according to the target address, so as to execute initialization operation on the display card according to the target data.

The initializing operation performed on the graphics card according to the target data may refer to an existing initializing operation of the graphics card, which is not described herein.

According to the method provided by the embodiment of the application, the VBIOS file which is provided with the index section and the data section and is stored in the linked list format is generated, and the target data in the data section corresponding to the index section can be rapidly positioned according to the relative position recorded in the index section only by reading the content of the index section in the initialization process of the display card, so that the position of the target data in the VBIOS file is obtained, and the initialization efficiency of the display card is improved. The VBIOS file which comprises the index segment and the data segment and is stored in the chain table format can improve the expansibility, the storage and the access efficiency of the VBIOS storage information.

Hereinafter, details of contents included in the VBIOS file will be described.

One possible implementation, the index further includes an index type identifier. The index type is used to classify the index, and may be classified by the action of the data corresponding to the index, or classified by the data type of the data corresponding to the index, for example. Illustratively, the format of the index may further include an index type, for example, as shown in table 2 below, based on table 1:

TABLE 2

In the index segment in the VBIOS file, the indexes may be arranged according to the index type, and the indexes included in the corresponding index type may be stored in a fixed memory address in the VBIOS file. In this implementation manner, when the processor in step S203 obtains the target address of the target data in the VBIOS file according to the target index of the target data and at least one index, the memory address range of the index type in the index segment of the VBIOS file may be determined according to the index type corresponding to the target index, and then the index corresponding to the target index is further matched in the memory address range, so as to further improve the access efficiency of VBIOS storage information, and improve the storage efficiency and expansibility of VBIOS storage information when the data in the VBIOS file needs to be updated. For example, according to the index type identifier corresponding to the target index, the index included in the index type corresponding to the identifier may be determined, or the memory address range of the index type in the index segment of the VBIOS file may be further matched with the index corresponding to the target index in the memory address range, so that the access efficiency of VBIOS storage information is further improved.

Illustratively, taking the VBIOS file as 256KB in size, the index type may be as shown in table 3 below:

TABLE 3 Table 3

In the case shown in table 3, the index segment may be stored beginning at a specific memory start location in the VBIOS file, and exemplary, the memory start location of the index segment in the VBIOS file may be a location offset from the start location of the VBIOS file by 0x 6000. The indexes in the index section are sequentially stored according to the index types in the above table 3.

Each number in table 3 corresponds to an index, and each index corresponds to data having a different function. The number may be a predefined number. As shown in table 3, for example, type numbers 0x1-0x1ff are device indexes, and indexes corresponding to other newly added data are extended for the device indexes by reserving 511 types of device number users; type numbers 0x200-0x5ff are configuration indexes, and 1024 configuration numbers are reserved for the configuration indexes; type numbers 0x600-0x1000 are code indexes, and 1024 code numbers are reserved; the index with the type number of 0xffff is an ending index to characterize the ending of the index segment; the numbers 0x1000-0xfffe are indexes to be extended for use as future extended other types of indexes.

Optionally, the data segment of the VBIOS file may further include VBIOS header data, where the VBIOS header data is used to describe structural information of the data in the VBIOS file, for example, may be used to describe a location (e.g., a start location, an end location, a data segment length, etc.) of the data segment in the VBIOS file, a location (e.g., a start location, an end location, an index segment length, etc.) of the index segment, or a location of other segments included in the VBIOS file. When the processor acquires the data in the VBIOS file, the processor can first read the VBIOS header data to obtain the layout of the VBIOS file, so that the starting position of the index section is quickly found, and the speed of matching indexes is increased. Optionally, the index segment may further include a VBIOS header data index type and a VBIOS header data index corresponding to the VBIOS header data.

In this implementation, before the aforementioned step S203 obtains the destination address of the destination data in the VBIOS file, the method may further include the following. Fig. 3 is a flowchart of another method for initializing a graphics card according to an embodiment of the present application. As shown in fig. 3, the method may further include:

s301, the processor acquires VBIOS header data.

The processor may obtain the location of the VBIOS header data in the VBIOS file according to a preset configuration, for example, the preset configuration is preconfigured in a software code of the graphics card initialization process, or in an attribute configuring the VBIOS file, etc. Or the VBIOS header data is configured at the beginning position in the VBIOS file, and when the processor analyzes the VB IOS file, the VBIOS header data is firstly acquired.

S302, the processor determines the starting position of the index segment in the VBIOS file according to the VBIOS header data.

Because the structure information of the VBIOS file is stored in the VBIOS header data, and the structure information includes the position information of each segment of the VBIOS file, the processor can obtain the starting position of the index segment in the VBIOS file according to the structure information of the VBIOS file stored in the VBIOS header data.

The step S203 of obtaining the target address of the target data in the VBIOS file includes:

s303, the processor traverses the index segment according to the initial position of the index segment in the VBIOS file to acquire the target address of the target data in the VBIOS file.

The processor starts from the starting position of the index segment in the VBIOS file and traverses to the ending position of the index segment in the VBIOS file, for example, the ending position of the index segment in the VBIOS file may be determined directly according to the ending address of the index segment obtained from the VBIOS header data, or traverses to the ending index in the table 3, so as to stop traversing.

And according to the matching of the index in the index section and the target index, acquiring the target address of the target data in the VBIOS file so as to extract the target data for initializing the display card.

According to the method provided by the embodiment of the application, the VBIOS header data is set to identify the structure of the data in the VBIOS file, so that the processor can be conveniently and quickly positioned to the position of the current section to be searched, and the expansibility, storage and access efficiency of the VBIOS storage information are further improved.

Alternatively, whereas VBIOS files are not typically used for initialization of a single version of a single graphics card, initialization operations for multiple graphics card versions are most of the time possible. Thus, the VBIOS file may also include historical data segments. The historical data segment comprises data of at least one display card stored in a historical VBIOS version, is compatible with display card driving of the historical version, and is used for initializing operation of the display card of the historical version.

The historical data segment may store the data required by the display card of the historical version in the initializing operation in a sequential table manner, or may store the data required by the display card of the historical version in the initializing operation in a manner of including the index segment and the data segment in the method of fig. 2-3.

In this implementation, before the aforementioned step S203 obtains the destination address of the destination data in the VBIOS file, the method may further include the following. Fig. 4 is a flowchart of another method for initializing a graphics card according to an embodiment of the present application. As shown in fig. 4, the method may further include:

s401, the processor detects the current version of the driver of the display card.

The processor can acquire the model and the basic information of the display card of the second electronic device by detecting hardware in the second electronic device. And acquiring the attribute of the driver of the display card according to the model and the basic information of the display card, and extracting the current version of the driver from the attribute.

S402, if the current version of the driver of the display card is the same as at least one historical VBIOS version included in the historical data segment, acquiring historical VBIOS data which is the same as the current version of the driver of the display card from the historical data segment.

If the current version of the driver of the graphics card is the same as at least one historical VBIOS version included in the historical data segment, the feature needs to use the data of the historical VBIOS version in the historical data segment to initialize the graphics card, so that the data corresponding to the historical VBIOS version needs to be matched from the historical data segment for initializing the graphics card.

If the current version of the driver of the graphics card is different from the historical VBIOS version included in the historical data segment, but is the same as the VBIOS version corresponding to the index included in the foregoing tables 1 to 3, the corresponding VBIOS data is obtained by the foregoing methods of fig. 2 to 3.

S403, extracting target data from the historical VBIOS data.

If the historical VBIOS data is stored data in the format of the sequence table, traversing the data table, and matching the corresponding required target data. If the format of the historical VBIOS data storage data is the same as the storage mode of the VBIOS file in fig. 2-3, the corresponding VBIOS data is obtained by using a method similar to that of fig. 2-3.

According to the method provided by the embodiment of the application, the historical data segments are arranged to store the historical VBIOS version data, so that the VBIOS file can provide the target data for initializing the display card of the corresponding version aiming at the driving of the display cards of a plurality of historical versions, and the compatibility of the VBIOS file is improved.

To facilitate understanding, the present application further provides a structure example of the VBIOS file, which takes the VBIOS file as 256KB as an example. Fig. 5 is a schematic structural diagram of a VBIOS file according to an embodiment of the present application. As shown in fig. 5, the structure may include: historical data segment, index segment, data segment.

The historical data segment comprises data corresponding to at least one historical VBIOS version. The index segment includes a plurality of index types as shown in the foregoing table 3, and a corresponding plurality of indexes. The data segment includes VBIOS header data, and data corresponding to each index in the index segment, the VBIOS header data may be located at the beginning of the data segment.

As shown in FIG. 5, the history data segment is located at the start position of the VBIOS file, the addresses of the history data segment are 0x0000 to 0x0400, a first reserved data segment exists between the index segment and the history data segment, the start position of the index segment is 0x6000, and the first reserved data segment is used for dividing the index segment and the history data segment. A second reserved data segment exists between the index segment and the data segment, the starting position of the data segment can be determined according to the ending position of the index segment and the length of the second reserved data segment, the second reserved data segment is used for dividing the index segment and the data segment, and sub-data segments for expansion are reserved in the historical data segment, the index segment and the data segment. The reserved sub-data segment for expansion may be, for example, a sub-data segment where the index to be expanded is located as shown in the foregoing table 3, and correspondingly, in the data segment and the history data segment, a similar sub-data segment may also be reserved for subsequent expansion of the VBIOS file.

In another possible implementation, the historical data segment is connected to an index segment, the index segment is connected to a data segment, and no reserved data segment exists between the segments.

In yet another possible implementation, there is at least one reserved data segment between the history data segment, the index segment, and the data segment.

The display card data to be newly added, and the index to be newly added, the index type identifier, and the like corresponding to the display card data to be newly added may be determined according to parameter changes caused by updating iteration of the display card version, for example, when the display card version is updated, new display card settings, display card functions, and the like may be configured, that is, corresponding data needs to be newly added. For the display card data to be newly added, the corresponding indexes to be newly added are required to be set and added into the VBIOS file together, so that the display card data can be quickly extracted according to the corresponding indexes.

The first electronic device may obtain the data by analyzing the parameters in the updated graphics card, or may obtain the data by receiving manually input data, which is not limited in the present application.

S602, the first electronic device adds the index to be newly added into the index section, and adds the display card data to be newly added into the data section.

The first electronic device may add the index to be newly added corresponding to the display card data to be newly added to the sub-data section for expansion in the index section, and add the display card data to be newly added to the sub-data section for expansion in the data section. For example, the index to be newly added is added at a position immediately after the last index in the existing index segment, and the graphics card data to be newly added is added at a position immediately after the last data in the data segment.

Optionally, if the type of the index to be newly added corresponding to the display card data to be newly added belongs to the existing index type in the VBIOS file, the type of the index to be newly added may be updated to the position to be expanded in the existing corresponding index types.

S603, the first electronic device constructs a mapping relation between an address of the display card data to be newly added in the data segment and the index to be newly added so as to update the display card data to be newly added to the VBIOS file.

The first electronic device inputs the address of the display card data to be added in the data section into the parameter used for storing the address in the new index to construct the mapping relation between the address of the display card data to be added in the data section and the new index according to the association between the display card data to be added and the new index, so that the update of the data of the display card stored in the VBIOS file is realized.

According to the method provided by the embodiment of the application, the VBIOS file comprises the data segment and the index segment, the sub-data segment for updating is reserved, and the updating of the display card data can be completed only by writing the display card data to be newly added in any blank position in the data segment and constructing the mapping relation with the newly added index, so that the writing position and the data length of the data are not required to be manually determined, the position of the existing data in the VBIOS file is adjusted, and the expansibility and the storage efficiency of VBIOS storage information when the VBIOS file is updated are improved.

By way of example, taking the VBIOS file as the VBIOS file structure shown in fig. 5, the initialization method of the graphics card is described by way of a specific example. Fig. 7 is a flowchart of a graphics card initialization method according to an embodiment of the present application. As shown in fig. 7, the method includes:

S701, VBIOS header data in a VBIOS file is acquired.

The form of the data stored in the VBIOS file is in a linked list form, that is, the logic sequence of the graphics card data stored in the data segment is stored according to the logic sequence of the pointers between the indexes included in the index segment and the corresponding graphics card data. And acquiring the position of the VBIOS header data in the VBIOS file according to the preset configuration, and extracting the VBIOS header data from the position.

For example, if the starting position of the historical data segment in the VBIOS file is 0x0000, the ending position is 0x0400, the starting position of the index segment is 0x6000, the ending position is 0x10000, the starting position of the data segment is 0x12000, and the ending position is 0x30000, the starting positions of the segments 0x0000, 0x6000, and 0x12000 may be included in the VBIOS header data. If the VBIOS header data further includes the end positions or lengths of the segments, the end positions are 0x0400, 0x10000, and 0x30000, respectively. The length then represents the length between the start position and the end position.

S703, according to the position of the historical data segment, the historical VBIOS version contained in the historical data segment is obtained and compared with the current version of the driver of the display card.

And if the current version of the driver of the display card is the historical VBIOS version included in the historical data segment, acquiring the historical VBIOS data which is the same as the current version of the driver of the display card from the historical data segment, and initializing the display card.

If the current version of the graphics card is not the historical VBIOS version included in the historical data segment, the step S704 is executed to characterize the data in the data segment to be acquired to initialize the graphics card.

S704, determining the index type corresponding to the target index in the index segment according to the target index corresponding to the target data in the position range of the index segment.

For example, if the index type corresponding to the target index is index type 1 shown in fig. 7, the content of index type 1 may be determined by traversing the index segment through the target index. The index type corresponding to the target index in the index segment may be determined, for example, by the index type identification described above.

S705, determining the index corresponding to the target index in the index segment in the memory address range of the index type corresponding to the target index in the index segment.

S706, determining the memory address of the target data in the data segment according to the pointer included in the index and the memory address pointed by the pointer.

The pointer may be implemented by any implementation manner of a pointer in the prior art, which is not limited in the present application. For example, the memory address pointed to by the index is data 1-3 in data 1 in FIG. 7, and the data 1-3 is the target data stored in the VBIOS file.

S707, obtaining target data according to the memory address of the target data in the data segment, so as to initialize the display card by using the target data.

Continuing with the example in S706, data 1-3 is extracted for initialization of the graphics card based on the memory address of the acquired data 1-3.

The first electronic device writes the data to be added into a reserved sub-data segment in the data segment of the VBIOS file (e.g., the new added data in the schematic diagram of the VBIOS file after the new added data in fig. 8B). And constructing a mapping relation between the address and the newly added index according to the address of the newly added display card data in the data segment so as to realize the construction of updating the display card data to be newly added to the VBIOS file.

If the type of the index to be newly added is different from the existing index type in the VBIOS file, the index to be newly added is newly added in a reserved sub-data segment in the index segment of the VBIOS file, and the new index type corresponding to the new index (e.g. the new index type in the schematic diagram of the VBIOS file after the data is newly added in fig. 8B) is written.
