The application relates to a service processing method, system, device and medium based on a dual real-time kernel. A real-time Linux kernel and a real-time virtual machine monitor kernel are constructed, and a message sharing channel is established between the real-time Linux kernel and the real-time virtual machine monitor kernel; according to a preset multidimensional task scheduling strategy and a preset resource allocation and isolation strategy, the real-time Linux kernel is responsible for system service process scheduling and resource allocation at an operating system level, and the real-time virtual machine monitor kernel is responsible for scheduling, device simulation and resource allocation of a virtual machine service. Through the dual real-time kernel, task scheduling is separated, and the efficiency of task scheduling can be effectively improved. Through the optimized multidimensional task scheduling strategy and the resource allocation and isolation strategy, task scheduling is controlled, and the scheduling delay and jitter of real-time tasks in system services and / or virtual machine services are improved in combination with hardware optimization. The system device and the medium based on the method provided by the application can also achieve the above effects.

Aspects of the present disclosure relate to dynamically configuring OS component capabilities based on energy consumption. More specifically, a method of the present disclosure includes generating a first map of information based on source code, where the first map of information comprises a function call tree of an OS component associated with the source code and energy usage of a host device of the OS component. The method includes generating a second map of information based on the source code, the second map of information indicating energy usage of active applications and active component loads in view of energy availability of the host device of the OS component. The method includes determining whether to activate or deactivate the OS component based on the energy availability of the host device, the first map of information, and the second map of information.

The application provides an operating system level dynamic operation and maintenance authorization method and system, the method comprises the following steps: receiving a user initiated access request; according to the access request, querying a preset mapping relationship configuration table to obtain a user field of a security context; determining the login mode of the user, and according to the login mode, obtaining a role field of the security context and a type field of the security context; according to the user field of the security context, the role field of the security context and the type field of the security context, obtaining a corresponding security context, and according to the security context, granting the user corresponding permissions. The application determines the operation permission of the user by obtaining the user field, the role field and the type field of the security context, so as to determine whether the corresponding access operation can be performed according to the access request, realizes the dynamic configuration of the execution permission of the user to the operation and maintenance software, and simultaneously controls the operation permission of other software started by the user to the operation and maintenance software.

Methods, systems, and devices for automating code analysis, dependency mapping, and adaptive task execution with artificial intelligence are described. In some implementations, a server platform may receive input data including a codebase and associated documentation. The server platform may parse the input data to extract task parameters, generate meta tags describing functions and dependencies, and construct a workflow representation of tasks, the workflow representation including operating-system-level input events and associated state transitions. The server platform may execute the workflow representation by generating the operating-system-level input events and verifying state transitions through a perception layer that captures pre-execution and post-execution states. Each executed input event and corresponding state transition may be logged in a provenance module with cryptographic metadata for secure auditability.

This invention discloses a data processing method for data streams, comprising: In this embodiment, the operating system obtains the dependency DAG graph of node tasks and data communication volume from the process block PCB of the program, wherein nodes in the dependency DAG graph represent node tasks, and edges connecting the nodes in the dependency DAG graph represent the transmission quantity and data volume of the node tasks; threads are allocated to node tasks based on ready nodes, direct successor nodes, and the total number of system threads in the dependency DAG graph; and threads are scheduled based on the current processor system load, node task communication relationships, and communication volume. This invention provides a support method for data stream execution mode at the operating system level, greatly improving its efficiency and optimization potential.
