CPU Power Consumption, Low‑Power Modes, and Core Control Framework
CPU power consumption comprises static leakage and dynamic switching energy, so modern SoCs use low‑power C‑states and core‑control isolation to shut down idle cores, with the kernel’s corectl module dynamically evaluating load and task counts each scheduler tick to decide how many CPUs to activate or deactivate, configurable via sysfs.
