Idle CPU power management: cpuidle

CNXSoft: This is a guest post by Daniel Thompson, Principal Software Engineer at RISCtar Solutions, about Linux CPU power management for embedded systems, specifically covering cpuidle in depth. Twenty years ago, it was easy for an operating system kernel to go idle: when there were no tasks to run, “the idle loop” would be scheduled. Early idle loops were basically empty infinite loops that did nothing while waiting for the next inte…
