Description

Didn't find anything regarding wake capable sources, in particular interrupts. Would be nice to shed a little light on the topic.

Research direction
Research Linux kernel wake capable sources and interrupts. Examine existing linux insides documentation structure (e.g., the Interrupts chapter at https://github.com/0xAX/linux insides/tree/master/Interrupts). Review kernel source code such as arch/x86/kernel/irq.c and related headers. Write a new section explaining how interrupts can be wake sources, covering hardware and software aspects. No prior work exists on this issue.
