Detailed Description

Normal IRQ callback interface.

Callbacks run in an ordinary kernel thread after the hard interrupt path has recorded the physical-line event. They may use thread-context APIs and are deliberately not given the interrupted processor state.

A recyclable message vector may deliver a late edge from its previous source. Opt in only when the callback verifies its own device's pending work and an empty invocation has no side effects.

Reimplemented in AhciController, and NvmeController.
