Description

Interrupt processing method, system and electronic equipment Technical Field The present application relates to the field of interrupt processing technologies for microkernel operating systems, and in particular, to an interrupt processing method, system, and electronic device. Background Microkernel operating systems are operating systems based on microkernel architecture, whose core idea is to "minimize the kernel", i.e. only keep the smallest and most critical core functions (e.g. functions of process scheduling, memory management, inter-process communication, etc.) in the microkernel, while most system services (e.g. services of file system, device driver, network protocol stack, etc.) are moved to user-mode process operation. This architecture promotes the modularity and flexibility of the system, but also presents a challenge of efficiently and safely notifying interrupt information in the hardware device to user-oriented processes in the microkernel operating system to better implement interrupt handling. Disclosure of Invention The application provides an interrupt processing method, an interrupt processing system and electronic equipment, which can more efficiently and safely inform interrupt information in hardware equipment to a user state process in a microkernel operating system so as to better realize interrupt processing. In a first aspect, an implementation manner of the present application provides an interrupt processing method, which is applied to an interrupt processing system, where the interrupt processing system includes a hardware device and a microkernel operating system, the microkernel operating system includes a microkernel and a user state process, the microkernel includes an interrupt management node and at least one interrupt endpoint, the user state process includes at least one interrupt service process, and at least one application node corresponding to each interrupt service process, and each interrupt service process registers a corresponding interrupt endpoint. The method comprises the steps that under the condition that the hardware equipment has an interrupt, corresponding interrupt information is sent to an interrupt management node in the micro-kernel, and the interrupt information comprises interrupt type identification information. The interrupt management node in the micro-kernel receives the interrupt information, determines the interrupt type corresponding to the interrupt information according to the interrupt type identification information included in the interrupt information, determines the interrupt endpoint corresponding to the interrupt information according to the interrupt type and the corresponding relation between the preset interrupt type and the interrupt endpoint, and sends the interrupt information to the corresponding interrupt endpoint. The interrupt service process is used as an interrupt monitoring receiver, monitors the registered interrupt endpoint, acquires interrupt information from the registered interrupt endpoint when the registered interrupt endpoint is monitored to have interrupt information, and sends the acquired interrupt information to the corresponding application node so that the application node can perform corresponding interrupt processing according to the interrupt information. In the technical scheme provided by the implementation mode of the application, an interrupt management node and at least one interrupt endpoint are arranged in the microkernel, the corresponding relation between interrupt types and interrupt endpoints is preset in the interrupt management node, the interrupt service process in the user state process registers the corresponding interrupt endpoint, and the interrupt service process is used as an interrupt monitoring receiver to monitor the registered interrupt endpoint so as to acquire the corresponding interrupt information. Therefore, under the condition that the interrupt management node in the microkernel receives the interrupt information sent by the hardware peripheral, according to the interrupt type corresponding to the interrupt information and the corresponding relation between the preset interrupt type and the interrupt endpoint, the interrupt information can be transmitted or routed to the corresponding interrupt endpoint, and further the interrupt information is acquired by the interrupt service process registered with the interrupt endpoint based on the monitoring mechanism, so that the purpose of transmitting the interrupt information in the microkernel to the interrupt service process in the user state process and finally transmitting the interrupt information to the corresponding application node in the user state process for corresponding interrupt processing is achieved, namely the purpose of notifying the interrupt information in the hardware device to the user state process in the microkernel operating system is achieved. Therefore, based on the corresponding relation of the inter
