Implementation and testing of real-time response to PCI interrupts based on RTLinux

This paper presents the implementation of real-time PCI interrupt response for a particular PCI device within the RTLinux operating system. It encapsulates the methodologies employed to achieve real-time responsiveness to PCI interrupts specifically within the RTLinux environment. The paper delves into the fundamental steps involved in the development process, the detailed execution of the implementation, the integration of the driver program's kernel module, and the harmonized operation between the user process and the driver program. The paper includes a thorough evaluation of the real-time performance based on the proposed implementation method. The test results are promising, demonstrating that the method not only exhibits strong real-time capabilities but also meets the stringent requirements of practical engineering applications.
