First embodiment
Fig. 3 is a basic flowchart of the kernel configuration method provided in this embodiment, and the method can be applied to any type of terminal device that needs to install terminal software and has an operating system, and is not limited to a mobile terminal, but also can be applied to other fixed terminals equipped with a security protection operating system, such as a digital television, a desktop computer, a navigator, and the like. The kernel configuration method comprises the following steps:
s301, confirming each created configuration file; the configuration files at least comprise two types, namely a first configuration file and a second configuration file, wherein the first configuration file corresponds to a chip manufacturer, and the second configuration file corresponds to an original equipment manufacturer;
s302, merging the configuration files to form merged configuration files;
s303, compiling the merged configuration file and configuring the kernel code of the operating system.
The terminal can not be produced without the support of hardware, the hardware source of the terminal is various, many hardware are not produced by OEM manufacturers, the hardware of the terminal is various after all, and if one manufacturer can manufacture all hardware of one terminal, the realization is not possible at present. It is therefore inevitable that many OEM manufacturers will acquire the corresponding hardware from other manufacturers that produce the associated hardware. The processor chip is the core of the whole terminal, and the performance of the processor is related to the running condition and the user experience of the whole terminal. The OEM produces the terminal based on the chips provided by other chip companies, and for the operating system kernel code of the terminal, the corresponding configuration items may be generated by the OEM or the chip manufacturer to achieve the expected effect.
The kernel code of the operating system is a code necessary for burning the kernel of the operating system when the terminal is produced, and is a precursor of the kernel of the operating system; and configuring the kernel code of the operating system, namely compiling each configuration file according to the configuration files generated by various manufacturers, and burning the kernel code of the operating system in a processor of the terminal to form the kernel of the operating system.
In S301, each profile that has been created is confirmed. Each configuration file is a core part in this embodiment, and the operating system kernel code can be configured based on the configuration files to form an operating system kernel. The configuration files at least comprise two types, namely a first configuration file and a second configuration file, wherein the first configuration file corresponds to a chip manufacturer, namely defconfig; the second configuration file corresponds to the OEM vendor, either diffconfig or OEM-config. The two types of configuration files identify the modification sources of the configuration files, so that the management convenience is improved. It should be noted that the configuration files described in this embodiment only relate to two types of configuration files, and in fact, the configuration files may also include other types of configuration files, such as configuration files corresponding to other terminal device manufacturers, which may be because the terminal is manufactured by a plurality of different manufacturers or different processes in the same manufacturer, and the configuration files may also be correspondingly set in a plurality according to these different execution subjects.
In S302, the configuration files are merged to form a merged configuration file. The configuration of the kernel should be performed from the whole configuration file, and therefore, separate configuration files need to be merged, and the kernel code of the operating system is configured by using the merged configuration file to complete the modification and update of the kernel code of the operating system. Wherein, before merging, the first configuration file is defconfig, and the second configuration file is diffconfig or oem-config, and after merging, the first configuration file is still treated as defconfig.
In S303, the merged configuration file is compiled, and the operating system kernel code is configured. After the compilation is completed, the modification and the update of the kernel code of the operating system are completed, and in this embodiment, each configuration file is merged only when the compilation is needed, so that after the merging, the merged configuration file is still split, or the corresponding first configuration file and the second configuration file are separated from the merged configuration file again.
In this embodiment, optionally, the corresponding configuration file may be updated based on modification information of the configuration file by the corresponding vendor. Since each configuration file corresponds to each vendor, the modification information, or configuration items, corresponding to the vendor should be modified for the corresponding configuration file. For example, if the configuration information is configuration information of a chip manufacturer, a first configuration file should be correspondingly modified; if the configuration information is the configuration information of the OEM manufacturer, the second configuration file is modified correspondingly to achieve the purpose of respective management, the management cost of the configuration of the kernel code of the operating system is reduced, the definition is improved, and the problem tracing operation is facilitated.
Specifically, the updating the corresponding configuration file in the modification information of the configuration file by the corresponding manufacturer may include: and modifying the merged configuration file by the configuration menu provided by the operating system kernel code, and automatically updating the second configuration file. The operating system kernel code provides a standard configuration menu, and the configuration menu is often presented to a user in a graphical interface mode, so that the user can operate intuitively. The merged configuration file is a configuration file capable of directly configuring the kernel code of the operating system, and obviously, the modified merged configuration file obtained after the operation of the merged configuration file can also be upgraded with the kernel code of the operating system. In this case, the second profile is updated after the merging, thereby realizing separate management of the first profile and the second profile.
Specifically, modifying the merged configuration file at the configuration menu provided by the kernel code of the operating system, and automatically updating the second configuration file may include: and separating the part which does not belong to the first configuration file in the modified merged configuration file based on the modified merged configuration file and the first configuration file, and updating the second configuration file based on the part which does not belong to the first configuration file. Due to the fact that most modifications are made by OEM manufacturers in the process of modifying the configuration file of the kernel code of the operating system, the configuration of the chip manufacturer is basically fixed after the chip manufacturer leaves the factory, that is, the first configuration file is basically fixed, and the second configuration file is often used for modification. The merged configuration file is merged from the first configuration file and the second configuration file, so that the merged configuration file and the first configuration file after modification can be compared with each other, and different parts are parts corresponding to the second configuration file. Since the second configuration file has already been merged with the first configuration file into a merged configuration file, the second configuration file at this point may be generated directly from the first configuration file and the modified merged configuration file, which is essentially an update to the second configuration file.
In addition, based on the modification information of the configuration file by the corresponding vendor, updating the corresponding configuration file may further include: and according to a preset modification specification, directly modifying in the created second configuration file. The modification process is different from the aforementioned modification process, the aforementioned modification process is to modify after the first configuration file and the second configuration file are merged, and the modification process is to modify before the first configuration file and the second configuration file are merged, and according to a preset modification specification, it means that a modification item corresponding to modification information is stored in the second configuration file according to a specified writing format. After the modification, the update of the second configuration file is completed, and then, when the kernel code of the operating system is to be configured, the first configuration file and the second configuration file may be merged to obtain a merged configuration file, and then the merged configuration file is compiled to configure the kernel code of the operating system, thereby completing the modification and the update of the kernel code of the operating system.
Specifically, in this embodiment, merging the configuration files, and forming a merged configuration file may include: and merging the configuration files through scripts. One optional script is a shell script, and the shell script create _ defconfig.sh is used for merging, so that the first configuration file defconfig and the second configuration file diffconfig are merged into defconfig for compiling an operating system kernel code. After the merging process, modifying the merged configuration file defconfig through a configuration menu provided by an operating system kernel code, namely make menuconfig, after the completion, generating a new merged configuration file defconfig modified by menuconfig through saveconfig, updating a second configuration file, namely update _ diff, through a shell script, separating new content in the modified merged configuration file from a source generation configuration file, namely a first configuration file, and forming a new second configuration file diffconfig.
In this embodiment, the modification information of the configuration file by the corresponding manufacturer may mainly include at least one of addition, deletion, and adjustment. Adding, namely adding corresponding configuration items in the configuration file; if the configuration file is deleted, the corresponding configuration item in the configuration file is removed; the adjustment is to modify the configuration items, possibly parameter values, on the basis of keeping the configuration items in the configuration file.
The embodiment provides a kernel configuration method, which aims at the problems of unclear direction of configuration items in kernel codes of an operating system and inconvenient management in the prior art, and confirms at least two types of created configuration files, which respectively correspond to an OEM and a chip manufacturer; and merging the configuration files to form a merged configuration file, compiling the merged configuration file, and configuring the kernel code of the operating system. Through the implementation of the embodiment, the source of the configuration of the kernel code of the operating system is determined in a manner that the configuration file is split based on a manufacturer, namely an initiator, so that the management cost of the configuration file is reduced.

S402, confirming modification information of the OEM to the second configuration file;
in the process of modifying the configuration file of the kernel code of the operating system, most modifications are carried out by OEM manufacturers, the configuration of a chip manufacturer is basically fixed after the chip manufacturer leaves a factory, that is, the first configuration file is basically fixed, and the modified configuration file is often the second configuration file.
S403, adding the modification information into a second configuration file according to a preset modification specification;
and according to a preset modification specification, storing a modification item corresponding to the modification information into a second configuration file according to a writing format of the specification. After the modification, the update of the second configuration file is also completed.
S404, merging the first configuration file and the second configuration file to form a merged configuration file;
