But what exactly is brought up when the device is in deep sleep then ? Is it only about keeping the minimal amount of electronic components on so that interrupts work, and wiring some interrupt handlers to the "load the rest of the OS" actions ?


The "whole operating system" (i.e. kernel) is up when the device is sleeping. It just doesn't do anything (i.e. no wifi, graphics, apps), so it won't consume much power either.
