Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of system rapid startup, and in particular to a rapid startup method, system, device and storage medium for an operating system. Background Art

[0002] System rapid startup has important application scenarios in many fields, especially in environments that require fast response and high efficiency, such as: Industrial automation: In industrial human-machine interface, industrial PLC and other scenarios, rapid startup technology can reduce system startup time, improve production efficiency and reduce resource waste; Internet of Things (IoT) devices: IoT gateways and communication management machines and other devices need to start quickly to ensure real-time transmission and processing of data; Embedded systems: In some embedded devices, it can ensure that the device starts and runs business applications in the shortest time.

[0003] System startup involves multiple stages, see Figure 3 After the system is powered on, Bootrom runs first to initialize the CPU, bus, and basic peripherals, and load BootLoader. BootLoader completes further hardware device initialization, loads the subsequent stage OS kernel and related components from the storage device into RAM, and jumps to the OS kernel entry address for execution. The OS kernel is the operating system kernel, which completes the initialization of the operating system and establishes the operating environment. The operating system starts the user application to provide business services.

[0004] Bootrom is usually fixed in the ROM inside the chip and provided by the chip manufacturer. The main work of system startup acceleration can be achieved by optimizing the BootLoader and the operating system.

[0005] The current general BootLoader software initially adopted a single-threaded design for reasons such as simplifying the design and reducing resources. All BootLoader work is executed serially. After the main CPU core (also called boot CPU) is powered on, it executes the main process of BootLoader, and the auxiliary CPU core (also called secondary cpus) enters a waiting state. When the operating system is started, the auxiliary CPU core in the waiting state is awakened to enter the multi-core SMP execution environment.

[0006] With the development of processors and hardware, CPUs are becoming more and more equipped with multiple cores and other resources. The original single-threaded design has gradually become a bottleneck in some scenarios that require fast startup.

[0007] In order to speed up the boot process, two methods are generally used: 1) Replace the BootLoader with one that supports multithreading. Use multithreading to perform different initialization tasks separately; 2) Simplify the process based on the existing BootLoader. Reduce the execution time by simplifying the functions.

[0008] However, replacing the BootLoader involves adjusting the overall chip software solution, which is heavily dependent on the chip manufacturer and is not feasible for chip application development. Simplifying the BootLoader process involves deep functional tailoring and customization, which is not universal. Summary of the invention

[0009] To this end, the embodiments of the present invention provide a method, system, device and storage medium for quickly starting an operating system to solve the technical problem that the prior art accelerates the startup by simplifying the BootLoader process, which involves deep function tailoring and customization, and is not universal.

[0047] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] With the development of processors and hardware, CPUs are becoming more and more equipped with multiple cores and other resources. The original single-threaded design has gradually become a bottleneck in some scenarios that require fast startup.

[0049] In order to speed up the boot process, two methods are generally used: 1) Replace the BootLoader with one that supports multithreading. Use multithreading to perform different initialization tasks separately; 2) Simplify the process based on the existing BootLoader. Reduce the execution time by simplifying the functions.

[0050] However, replacing the BootLoader involves adjusting the overall chip software solution, which is heavily dependent on the chip manufacturer and is not feasible for chip application development. Simplifying the BootLoader process involves deep functional tailoring and customization, which is not universal.

[0051] In order to solve the technical problem that the above-mentioned accelerated startup method by simplifying the BootLoader process involves deep function tailoring and customization, and is not universal.

[0052] refer to Figure 1 The embodiment of the present invention discloses a fast startup system of an operating system, which includes: a BootLoader loading module 1; an auxiliary CPU core wake-up module 2; a job distribution module 3; an exit executor module 4; and an OSkernel running module 5.

[0053] Corresponding to the above disclosed operating system quick startup system, the embodiment of the present invention further discloses an operating system quick startup method. The following describes in detail the operating system quick startup method disclosed in the embodiment of the present invention in combination with the above described operating system quick startup system.

[0054] refer to Figure 2 and Figure 4 The present invention discloses a method for quickly starting an operating system. The method is applied to BootLoader, and a job scheduler and a job executor are deployed in BootLoader to realize a distribution and scheduling communication mechanism of jobs.

[0055] Implement the job scheduler and execution unit in the bootloader and implement the job distribution scheduling communication mechanism.

[0056] After the power supply is connected and the operating system is started, the BootROM is run and the BootLoader is loaded, the main CPU core initializes the job scheduler, and the auxiliary CPU core enters a waiting state.

[0057] After the system is powered on, the main CPU core executes the existing process, and the auxiliary CPU core enters the waiting state first. The main CPU core sets and wakes up the auxiliary CPU core to enter the job executor and wait for the job to be executed. The specific number of auxiliary CPU cores to be used can be set by the main CPU core.

[0058] The main CPU core wakes up the auxiliary CPU core through the wake-up mechanism, so that the auxiliary CPU core enters the job executor and waits to execute the job; the main CPU core converts the initialization work into a job, distributes the job to the job executor of the auxiliary CPU core through the job scheduler for execution, and returns the execution result to the job scheduler after execution is completed.

[0059] During the execution of the main CPU, the time-consuming initialization work is used as a job to trigger the execution of the auxiliary CPU core, and the job execution unit is used for parallel initialization, including: parallel initialization of different peripheral drivers, reading and loading of large files, and other time-consuming initialization work. The software process on the main CPU core distributes the task function to the job execution unit on other CPU cores by calling the job scheduler interface. After the job execution unit is executed, the status is returned to the job scheduler. The main CPU core can check the completion status of the job in the subsequent process.

[0060] After the execution process is completed, the job executor is closed, and the main cpu core sends an exit executor command. After receiving the exit executor command, the auxiliary cpu core exits the executor and enters a waiting state, completing the BootLoader; the operating system is initialized and the operating environment is established through the OSkernel, and the operating system is started.

[0061] When the main CPU core starts, it wakes up the auxiliary CPU core from the initial waiting state and enters the job execution unit. When the bootloader ends, the main CPU core notifies the auxiliary CPU core to exit the execution unit and enter the initial waiting state.

[0062] Implement the job scheduler and executor (Job ExecutionUnit) in the bootloader. The job executor can execute the functional functions in the bootloader.

[0063] Furthermore, the job executor is used to execute the functional functions in the BootLoader.

[0064] Furthermore, the main cpu core wakes up the auxiliary cpu core through the wake-up mechanism, so that the auxiliary cpu core enters the job executor and waits to execute the job, including: obtaining auxiliary cpu core required quantity data; the main cpu core sets each auxiliary cpu core according to the auxiliary cpu core required quantity data and wakes up the auxiliary cpu core.

[0065] Furthermore, the main CPU core converts the initialization work into a job, distributes the job to the job executor of the auxiliary CPU core for execution through the job scheduler, and returns the execution result to the job scheduler after execution, including: distributing the task function to the job executor of the auxiliary CPU core for execution by calling the interface of the job scheduler.

[0066] The job distribution process is an asynchronous execution process that is executed multiple times.

[0067] Furthermore, the initialization work includes parallel initialization of different peripheral drivers, reading and loading of large files, and other time-consuming initialization work.

[0068] Furthermore, after the execution process is completed, the job executor is closed, and the main cpu core sends an exit executor command. After receiving the exit executor command, the auxiliary cpu core exits the executor and enters a waiting state to complete the BootLoader, including: the main cpu core triggers the auxiliary cpu core through the job executor to re-enter the waiting state, waiting for the subsequent operating system kernel to re-wake up the auxiliary cpu core.

[0069] When the bootloader is about to enter the OS kernel after execution, the main CPU core triggers the auxiliary CPU core through the job execution unit to re-enter the waiting state, waiting for the subsequent operating system kernel to wake it up again.

[0070] Furthermore, the method also includes: a queue mechanism based on shared memory is provided between the job scheduler and the job executor, for implementing task delivery and status query.

[0071] A shared memory-based queue mechanism is used between the scheduler and the executor to implement task delivery and status query.

[0072] The main CPU core distributes the time-consuming work to the execution unit of the auxiliary CPU through the scheduler for execution. The executor returns the result to the scheduler, and the main CPU core can query the execution status at an appropriate time later.

[0073] In addition, an embodiment of the present invention also provides a quick startup device for an operating system, the device comprising: a processor and a memory; the memory is used to store one or more program instructions; the processor is used to run one or more program instructions to execute the steps of a quick startup method for an operating system as described in any of the above items.
