PSCI is an interface that coordinates power management between the CPU and the platform firmware. On ARMv8 systems, PSCI is commonly used to control power operations. Linux uses either PSCI or spin-table to control CPU power depending on the platform's DT bindings. PSCI functions like CPU on, off, and system suspend are invoked from Linux drivers through SMC calls to the firmware. This allows the platform firmware to implement features like low power states.
