Energy-aware scheduling on asymmetric systems

Energy-aware scheduling — running a system's workload in a way that minimizes the amount of energy consumed — has been a topic of active discussion and development for some time; LWN first covered the issue at the beginning of 2012. Many approaches have been tried during the intervening years, but little in the way of generalized energy-aware scheduling work has made it into the mainline. Recently, a new patch set was posted by Dietmar Eggemann that only tries to address one aspect of the problem; perhaps the problem domain has now been simplified enough that this support can finally be merged.
