BKK16-410: SoC Idling & CPU Cluster PMAdded to BKK16 Resources on Monday, February 22, 2016
The linux kernel has two distinct ways of managing idle. The CPUidle framework for CPUs and for all other devices: runtime PM combined with generic power domains (genpd). In addition, CPUidle is not scaling well for multi-cluster SMP systems and heterogeneous systems like big.LITTLE. To better manage idle for modern SoCs with a hierarchical structure, we are exploring extending runtime PM and genpd to CPUs so there is a unified framework for managing idle across all devices.
