Detailed Description

Explicit hard-IRQ callback interface.

Directly deriving from this class opts the whole callback into hard IRQ context, where it must not block, allocate, invoke arbitrary callbacks, or retain InterruptState. SplitIrqHandler is only for devices which require a mandatory hard top half; it is not the normal threaded-delivery API.
