Equipment management system and method

Abstract

The invention discloses an equipment management system and method, and belongs to the technical field of computer operating systems. The equipment management system comprises a driving module, an equipment management module, a detection unit, a creation unit, an allocation unit and a processing unit. The equipment management method comprises the following steps: S1, detecting all hardware devicesconnected with a microkernel operating system, and creating a corresponding device tree; S2, creating a virtual bus for each piece of hardware equipment; and S3, distributing the virtual bus to a corresponding driving program. According to the technical scheme, the beneficial effects are as follows: unified management of hardware equipment access by the equipment driving program is realized, and ahardware equipment management strategy is introduced, so that malicious access of an untrusted equipment driving program to hardware equipment is solved while independent operation of the equipment driving program in a user space is guaranteed, and strong isolation of the equipment driving program and a microkernel is achieved, and whole crash of an operating system caused by defects of the driving program is avoided.

Description

technical field [0001] The invention relates to the technical field of computer operating systems, in particular to an equipment management system and method. Background technique [0002] The microkernel operating system is an operating system based on the microkernel architecture. The microkernel is composed of a group of software programs that minimize the number as much as possible. They are responsible for providing the most basic mechanisms and functions required to implement an operating system, such as threads. management, memory address space management, and interprocess communication. The microkernel operating system is divided into kernel space and user space. The microkernel runs in the kernel space, while system services such as device drivers, file systems, and network protocols run in the user space of the operating system. [0003] A device driver is a program that manipulates a hardware device. It is a bridge between the hardware and the application program...

AI Technical Summary

Problems solved by technology

The device driver is an important part of the operating system. In the macro-kernel operating system, the device driver runs in the kernel space of the operating system, so that the device driver has full control over the hardware device resources, which can ensure the maximum performance of the operating system. , however, due to the tight coupling between the device driver and the kernel, if there is a defect in the device driver, it will cause the entire operating system to crash

In the microkernel operating system, since the device driver runs in the user space of the operating system, the above problems will not occur, which will help to strengthen the stability and security of the system, but the functions of the device driver will be limited, such as , the device driver cannot directly manipulate hardware devices, cannot perform direct memory access, cannot directly use interrupts, etc. In addition, because there is no corresponding hardware device management strategy, untrusted device drivers will easily manipulate hardware devices maliciously
