Explore the intricacies of Linux kernel interrupt delivery configuration in this informative conference talk. Delve into how the Linux kernel interacts with hardware to manage interrupts, covering key topics such as Interrupt Descriptor Table (IDT) configuration, CPU selection for new interrupt requests, and the configuration of interrupt controllers and MSI devices. Examine the differences between hwirq, vector, and virq through demonstrations using gdb/crash utility. Gain a deeper understanding of interrupt delivery mechanisms, building upon the Linux Kernel Teaching lecture on interrupts. Learn how device drivers register hardware interrupts and how the kernel routes them to specific CPUs, providing valuable insights for developers and system administrators working with Linux systems.
