On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] Terminology explanation:

[0042] Compiler for heterogeneous hybrid systems: An automated tool used to generate user-usable targets from source code; usable targets include libraries, executable files, scripts, etc.

[0043] RTOS system: real-time operating system.

[0044] Linux system: open source operating system.

[0045] OPTEE system: an open source portable trusted execution environment.

[0046] QNX system: A Unix-like real-time operating system that complies with the POSIX specification.

[0047] Android system: A free and open source mobile operating system based on the Linux kernel (excluding GNU components). Mainly used in mobile devices such as smartphones and tablets.

[0050] C / C++: Systems-level programming language.

[0052] CMake: Used to generate Makefile files, including tools, syntax formats, keywords, functions and a set of rules.

[0053] Since the existing compilation scheme is usually only developed for one operating system and its running applications and system software, different operating systems and their applications and system software use different build systems, for example, referring to CMake as the core, combined with Shell Script, Python and other compilation tools compilation system; or referring to AliOS Xmake as the core, by writing mk files to build AliOS xmake system; or using Java Script, or C / C++ and other languages ​​to develop Android system, etc., can only be developed for their own operating systems, and cannot support the compilation and construction of various different operating systems and their system software in heterogeneous hybrid systems in the same set of compilation devices. To this end, the embodiment of this specification provides a compilation method for heterogeneous hybrid systems, by parsing the overall construction environment configuration of any system to be compiled in the heterogeneous hybrid system, obtaining tool chain requirement information and compilation configuration of several modules to be compiled; on the one hand, according to the tool chain requirement information, the tool chain is configured on demand, and on the other hand, according to the compilation configuration, the compilation tasks and relationship structure maps of several modules to be compiled under the system to be compiled are constructed for compilation preparation. After preparation, refer to the relationship structure map, use the corresponding configured tool chain to process the compilation tasks of several modules to be compiled until the compilation is completed, and create an independent tool chain compilation environment for each compilation task to perform the compilation operation. It can be seen that the present technical solution can support parsing the tool chain requirement information and compilation configuration required for any system to be compiled in a heterogeneous hybrid system, configure the required tool chain on demand, and create an independent tool chain compilation environment to perform the compilation of various compilation tasks. Therefore, it can support the compilation and construction of various operating systems and their system software in a heterogeneous hybrid system, so that various operating systems and their system software in a heterogeneous hybrid system can be compiled and constructed in the same set of compilation devices, thereby reducing the development cost of the heterogeneous hybrid system.

[0054] See also Figure 1 , is a flow chart of a compilation method for a heterogeneous hybrid system provided in an embodiment of this specification. The method comprises the following steps:

[0055] S101, parsing the overall construction environment configuration of any to-be-compiled system in the heterogeneous hybrid system, and obtaining tool chain requirement information and compilation configuration of several to-be-compiled modules.

[0056] In this embodiment, the type and number of systems to be compiled in the heterogeneous hybrid system are not limited. For example, RTOS systems, QNX systems, and Linux systems for autonomous driving, Android systems and Linux systems for smart cockpits, OPTEE operating systems for security protection, etc., can all be used as systems to be compiled. Each system to be compiled has its own different overall build environment configuration. The overall build environment configuration of the system to be compiled is mainly used to describe the relevant configuration of the overall build environment of the system to be compiled, such as several modules to be compiled, tool chain requirements, dependencies, build methods, compilation actions, etc. contained in the system to be compiled. Exemplary, for example, the system to be compiled is a safetylinux system, and each software package (module to be compiled) in the safetylinux system has a separate configuration. The configuration of the same part can be shared by include or inherit.

[0057] Set the toolchain through alios-toolchain configuration. In local.conf, set all the required toolchain paths through specified variables, and the build system will automatically verify and set these toolchain environments. At the same time, in multi-complers.conf, specify the toolchain it depends on for each software package through the TOOLCHAIN ​​variable. After loading and parsing, the compiler in this manual will automatically set the relevant toolchain for the module to be compiled.

[0058] Through the safetylinux-rootfs configuration, the overall build environment is set for all software packages. These software packages can be divided into bsp, multimedia, graphics, devtools, etc. in the operating system. For a certain software package module, do_configure, do_compile, do_install, do_package are used to complete the process of compiling configuration generation, compiling, installing and generating binary installation packages.

[0059] Let's take a small module as an example, such as compiling a helloworld program, but we need to use rust cross-compilation. The example is as follows:

[0060]

[0061] DESCRIPTION is the description information. This small module has no dependencies, so DEPENDS is empty. When compiling, the tool chain is specified as rustc through the TOOLCHAIN ​​variable. When compiling the helloworld module, the build system will create a rustc tool chain environment for the module. The tool chain environment is set through the rustc configuration. The example is as follows:

[0062]

[0063] The CARGO variable is specified here, and the rustc toolchain is checked to see if it is available. After the build system starts parsing the configuration, it checks the toolchain. Then it assigns a compilation task to helloworld. When the compilation task is executed, the entire toolchain environment, root file system and other basic environments are built. During the actual compilation, helloworld is compiled using CARGO through the compilation action specified by do_compile in the previous configuration. The do_install installation operation is ignored.

[0064] The above is the compilation process of a helloworld module.

[0065] The overall construction environment configuration is not integrated with the source code of the system to be compiled, and the source code of the system to be compiled exists separately, for example, is stored separately on a server and can be directly downloaded when used.

[0066] Before parsing, import the basic environment configuration, such as commonly used compilation tools, such as Shell, Python, etc. All compilations are prepared for the cross-compilation environment, and the compilation device itself in this manual uses the local host environment. The basic environment configuration is the necessary configuration that depends on the local host environment. For example, the shell environment and its necessary command line tools, the gcc compiler environment used to compile the host tool, the host python environment required to run the python script, etc.

[0067] When parsing the overall build environment configuration of the system to be compiled, the toolchain requirement information and compilation configuration of each of the several modules to be compiled contained in the system to be compiled are parsed. Among them, the toolchain includes the compiler and related database used for compilation. The compilation configuration includes all configuration files used to compile the model to be compiled. Specifically, the compilation configuration includes information such as the specified dependencies, compilation parameters, and compilation actions of the module to be compiled. It is worth noting that each module to be compiled has its own different toolchain requirement information and compilation configuration.

[0068] After obtaining the parsing results, the toolchain environment is checked according to the toolchain requirement information of several modules to be compiled. For example, it is checked whether the compiler version meets the compiler requirements in the toolchain requirement information, and whether the compiler is available.

[0069] S102, configuring a corresponding tool chain according to tool chain requirement information of a number of modules to be compiled.

[0070] In this embodiment, different tool chains are configured as needed for different modules to be compiled, and independent tool chain compilation environments will be configured for different modules to be compiled later, and compilation operations are performed in their own independent tool chain compilation environments. Even if the types or versions of compilers and databases used by different modules to be compiled conflict, the compilation will not be affected, so as to achieve better performance effects of compiler optimization. Of course, the same module to be compiled may use multiple different types of tool chains. Specifically, the system to be compiled contains several different types of modules to be compiled and their tool chains. For example, c / c++ modules and their configured tool chains: gcc, clang, etc. Tool chains configured for different types of software modules: gcc, rustc, etc. Different tool chains have different compilation effects, so by allowing different modules to be compiled to be configured with different tool chains, it is possible to take advantage of the differences in tool chains to obtain better compilation effects.

[0071] S103, constructing corresponding compilation tasks according to the compilation configurations of the modules to be compiled; and constructing a relationship structure graph according to the compilation configurations of all the modules to be compiled.

[0072] In this embodiment, respective compilation tasks are created according to the compilation parameters and compilation actions of several modules to be compiled in the compilation configuration. A compilation task is created for each module to be compiled. And, in combination with the specified dependencies in the compilation configuration of all modules to be compiled, a relationship structure map is constructed. Specifically, each module to be compiled has specified dependencies in its compilation configuration. Take the modules to be compiled: module A, module B, and module C as an example. Module A specifies the dependency module B, and module B specifies the dependency module C. According to this specified dependency, a dependency relationship link of module C→module B→module A can be constructed. In combination with the dependency relationship links of all modules to be compiled, a relationship structure map is constructed.

[0073] Among them, the relationship structure map is used to characterize the compilation dependencies of all modules to be compiled. It is worth noting that the relationship structure map contains both modules to be compiled with dependency links and independent modules to be compiled without dependencies. Furthermore, if the module to be compiled has a dependency link, it is necessary to first compile the module to be compiled in the inherited position in the dependency link. For example, in the dependency link of module C→module B→module A, module C is in the first inherited position, module B is in the second inherited position, and module A is in the inherited position. It is necessary to compile in the order of module C, module B, and module A. If the compilation of module C in the first inherited position fails, the dependency link as a whole is unavailable. If the module to be compiled has no dependency link, the module to be compiled can be directly compiled, and the compilation result of the module to be compiled will not affect the modules to be compiled in other links.

[0074] S104, referring to the relationship structure map, using the corresponding configured tool chain to process the compilation tasks of several modules to be compiled until the compilation is completed.

[0075] For each compilation task, an independent tool chain compilation environment is created to perform the compilation operation.

[0076] In order to facilitate the management of compilation tasks of several modules to be compiled, the compilation tasks are added to the task list for management, and a real-time check is made to see whether all the compilation tasks in the task list have been compiled. If not, the compilation tasks are selected in the task list for compilation based on the constructed relationship structure graph. If all the compilation tasks in the task list have been compiled, the process ends.

[0077] When selecting compilation tasks, a topological structure of all compilation tasks is constructed according to the relationship structure map; according to the topological structure, one or more compilation tasks without dependencies are preferentially selected for processing. Specifically, when multiple compilation tasks without dependencies are selected, they can be processed in parallel to improve compilation efficiency. When the compilation tasks without dependencies are selected, compilation tasks with dependency links are selected for processing. When selecting compilation tasks with dependency links, the dependency links can be selected randomly, and then the compilation tasks are selected from the dependency links in the order of inheritance for processing; or the dependency links can be selected according to the principle of the number of compilation tasks from small to large, and then the compilation tasks are selected from the dependency links in the order of inheritance for processing. Of course, the above two selection methods are only for illustration and do not constitute a limitation.

[0078] The compilation process for each compilation task is similar, so this embodiment takes the compilation process of a single compilation task as an example for description, and other compilation tasks can refer to the compilation.

[0079] During the compilation process of a single compilation task, after checking the execution environment of the compilation task, the compilation task is officially executed, and the final binary file is generated through the configured tool chain.

[0080] In the specific implementation process, first, for the compilation task, refer to the tool chain configuration of the module to be compiled to which the compilation task belongs, create a corresponding tool chain compilation environment, and execute the compiler to compile the source code to generate the target code. Specifically, in the overall construction process of the system to be compiled, several modules to be compiled will be parsed, and each module to be compiled can be set up with an independent tool chain compilation environment. The tool chain compilation environment of each compilation task is independent of each other and does not affect each other, thereby supporting different compilers to complete the source code compilation of each operating system and its running applications and system software. Further, according to the dependency relationship of the module to be compiled to which the compilation task belongs, the root file system, auxiliary tools, etc. required for compilation are constructed for compilation. After the compilation preparation work is done, the source code corresponding to the compilation task is obtained. Specifically, the source code of the compilation task exists separately in storage devices such as servers and databases. Therefore, it is necessary to download the source code according to the handshake between the two parties. After downloading, check the legality and correctness of the source code, and merge it into the patch file prepared for the source code. In the corresponding tool chain compilation environment, the configured tool chain is used to compile the source code into the target code.

[0081] It is worth noting that in order to complete the compilation task faster, the compilation task can be split into smaller-grained compilation subtasks by stage according to the execution actions in the compilation task, and processed in the corresponding tool chain compilation environment.

[0082] When the compilation is completed, the target code is installed to the set location so that it can be called by other compilation tasks that have dependencies on the compilation task. For example, if the compilation task corresponding to module C is completed, the compilation task corresponding to module C is stored in the specified location so that the compilation task corresponding to module B can be called when needed.

[0083] Furthermore, the target code is verified and the corresponding software package is made according to the packaging requirements for subsequent use.

[0084] When the compilation task is completed, the file dependency check and the runtime environment dependency check are performed.

[0085] In an optional implementation, the success of the compilation task (i.e., whether the compilation is completed) is monitored in real time. If the compilation fails, the corresponding topological link and other tasks that depend on the compilation task are deleted from the topological structure. Taking the compilation tasks corresponding to the order of module C, module B, and module A as an example, if the compilation of the compilation task corresponding to module C fails, the dependency link as a whole is unavailable, and the corresponding topological link and other tasks that depend on the compilation task are deleted, and the next compilation task is continued to perform the compilation. Exemplarily, other compilation tasks that have no dependency on the compilation task corresponding to module C are selected for compilation. If the compilation is successful, the next compilation task is directly transferred to perform the compilation until the compilation tasks corresponding to all modules to be compiled are compiled.

[0086] To illustrate and explain the overall compilation logic in the present invention, refer to Figure 2 .

[0087] S201, executing source code compilation of any system to be compiled in the heterogeneous hybrid system.

[0088] Among them, after the source code compilation of the system to be compiled is completed, it can be stored separately in the server and directly downloaded when used.

[0091] Furthermore, after the toolchain requirement information and compilation configuration of several modules to be compiled, the toolchain environment is checked accordingly.

[0092] S204: Configure corresponding tool chains according to tool chain requirement information of several modules to be compiled.

[0093] Among them, different tool chains are configured as needed for different modules to be compiled, and independent tool chain compilation environments will be configured for different modules to be compiled later. Compilation operations are performed in their respective independent tool chain compilation environments, and the best compilation performance is obtained by utilizing the different advantages of the tool chains.

[0094] S205: Construct corresponding compilation tasks according to the compilation configurations of the modules to be compiled.

[0097] S208: Select a compilation task in the task list according to the constructed relationship structure graph.

[0098] Start compiling.

[0099] During the execution of the compilation task, S209 is executed to create a corresponding tool chain compilation environment by referring to the tool chain configuration of the module to be compiled to which the compilation task belongs.

[0100] S210, constructing a root file system and auxiliary tools required for compilation according to the dependency relationship of the modules to be compiled to which the compilation task belongs.

[0101] S211, obtaining source code corresponding to the compilation task.

[0102] S212, merge the patch file prepared for the source code.

[0103] S213, in a corresponding tool chain compilation environment, using the configured tool chain to compile the source code into target code.

[0104] S214, when the compilation is completed, the target code is installed to a set location so that it can be called by other compilation tasks that have a dependency relationship with the compilation task.

[0105] S215, verify the target code and make a corresponding software package according to the packaging requirements.

[0106] S216, executing file dependency check and operating environment dependency check.

[0107] S217, real-time monitoring of whether the compilation task is completed. If completed, transfer to S207. If a compilation error occurs, execute S218, interrupt the compilation task, delete the corresponding topological link and other tasks that depend on the compilation task from the topological structure, and transfer to S207.

[0108] It is worth noting that any system to be compiled in a heterogeneous hybrid system can be compiled according to the compilation method introduced in the embodiments of this specification, so as to support the compilation and construction of various operating systems and their system software in the heterogeneous hybrid system, thereby reducing the development cost of the heterogeneous hybrid system.

[0109] In order to further illustrate and explain the compilation method in this specification, a specific example is used for illustration below.

[0110] Compile the safetylinux system. Set the toolchain environment required by the safetylinux system through the alios-toolchains configuration set, set the configuration of all modules to be compiled through the safetylinux-rootfs configuration set, and start the compilation device in this manual to compile. During the compilation process, the compilation device first parses all configurations, builds a dependency tree according to the module dependencies and creates a task list, and builds tasks in order according to the task list through the topological order. Until all compilation tasks are compiled, the root file system and image of the safetylinux operating system are generated, and the compilation is completed.

[0111] Compile the RTOS system. Set the toolchain environment of the RTOS operating system through the alios-toolchains configuration set, set the configuration of all RTOS modules to be compiled through the rtos-rootfs configuration set, and then start the compilation device in this manual to compile. During the compilation process, after the compilation device parses all configurations, it builds a dependency tree according to the module dependencies and creates a task list. Then compile in the order of the task list until all tasks are compiled, generate the root file system and system image, and complete the compilation of the RTOS system.

[0112] Based on the same inventive concept as in the aforementioned embodiment, the embodiment of this specification also provides a compilation device for a heterogeneous hybrid system, which can support the compilation and construction of various operating systems and their system software in the heterogeneous hybrid system, so that various operating systems and their system software in the heterogeneous hybrid system can be compiled and constructed in the same set of compilation devices, thereby reducing the development cost of the heterogeneous hybrid system.
