In this video, we explore GPIO interrupt handling in the Linux kernel using a Raspberry Pi.
You’ll learn how GPIO interrupts work, how to handle button debouncing, and how Linux splits interrupt handling into Top Half and Bottom Half.
We also compare the legacy GPIO API with the modern GPIO descriptor-based API, and demonstrate how to handle interrupts correctly inside a kernel module.
Topics covered:
GPIO interrupt handling
IRQ registration and cleanup
Button debouncing using kernel timers
Top Half vs Bottom Half (workqueues)
Legacy GPIO API vs Descriptor API
