rust: irq: fix C header path in module docs

2026-07-20T22:48:45+00:00

The IRQ module documentation displays `include/linux/device.h`, while the link points to `include/linux/interrupt.h`. The module wraps the IRQ registration interfaces declared in `include/linux/interrupt.h`, so fix the displayed header path.

rust: irq: add support for threaded IRQs and handlers

2025-08-12T18:22:09+00:00

This patch adds support for threaded IRQs and handlers through irq::ThreadedRegistration and the irq::ThreadedHandler trait. Threaded interrupts are more permissive in the sense that further processing is possible in a kthread. This means that said execution takes place outside of interrupt context, which is rather restrictive in many ways. Registering a threaded irq is dependent upon having an IrqRequest that was previously allocated by a given device. This will be introduced in subsequent patches.

rust: irq: add flags module

2025-08-12T18:04:22+00:00

Manipulating IRQ flags (i.e.: IRQF_*) will soon be necessary, specially to register IRQ handlers through bindings::request_irq(). Add a kernel::irq::Flags for that purpose.
