CONFIG_ENERGY_MODEL: Energy Model for devices with DVFS (CPUs, GPUs, etc)

General informations

The Linux kernel configuration item CONFIG_ENERGY_MODEL has multiple definitions:

Energy Model for devices with DVFS (CPUs, GPUs, etc) found in kernel/power/Kconfig

The configuration item CONFIG_ENERGY_MODEL:

• prompt: Energy Model for devices with DVFS (CPUs, GPUs, etc)
• type: bool
• depends on: ( CONFIG_SMP ) && ( CONFIG_CPU_FREQ )
• defined in kernel/power/Kconfig
• found in Linux kernels: 5.12–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

Several subsystems (thermal and/or the task scheduler for example) can leverage information about the energy consumed by devices to make smarter decisions. This config option enables the framework from which subsystems can access the energy models.

The exact usage of the energy model is subsystem-dependent.

If in doubt, say N.
