Feedback form is now closed.
Interrupt is one of the important mechanisms of the Linux kernel, vector and APIC tell the kernel how to operate the interrupt. With the development of the kernel, the old code led to many problems, such as vector space exhaustion, vector allocation chaos, kdump failure, Timer setup error, etc.,

Recently, Thomas Gleixner and Dou Liyang conducted a major overhaul. In this presentation,
Dou will describe the main process of interrupt initialization, discuss the challenges it faces,
describe what does the overhaul do and explain how it may address those challenges.
