CONFIG_CPU_THERMAL: Generic cpu cooling support

General informations

The Linux kernel configuration item CONFIG_CPU_THERMAL has multiple definitions:

Generic cpu cooling support found in drivers/thermal/Kconfig

The configuration item CONFIG_CPU_THERMAL:

• prompt: Generic cpu cooling support
• type: bool
• depends on: CONFIG_THERMAL_OF
• defined in drivers/thermal/Kconfig
• found in Linux kernels: 5.2–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: cpu_cooling

Help text

Enable the CPU cooling features. If the system has no active cooling device available, this option allows to use the CPU as a cooling device.

generic cpu cooling support found in drivers/thermal/Kconfig

The configuration item CONFIG_CPU_THERMAL:

• prompt: generic cpu cooling support
• type: bool
• depends on: ( CONFIG_CPU_FREQ ) && ( CONFIG_THERMAL_OF ) && ( CONFIG_THERMAL = CONFIG_y )
• defined in drivers/thermal/Kconfig
• found in Linux kernels: 3.7, 3.10–3.19, 4.0–4.20, 5.0–5.1
• modules built: cpu_cooling

Help text

This implements the generic cpu cooling mechanism through frequency reduction. An ACPI version of this already exists (drivers/acpi/processor_thermal.c). This will be useful for platforms using the generic thermal interface and not the ACPI interface.

If you want this support, you should say Y here.

generic cpu cooling support found in drivers/thermal/Kconfig

The configuration item CONFIG_CPU_THERMAL:

• prompt: generic cpu cooling support
• type: tristate
• depends on: CONFIG_CPU_FREQ
• defined in drivers/thermal/Kconfig
• found in Linux kernels: 3.8–3.9
• modules built: cpu_cooling

Help text

This implements the generic cpu cooling mechanism through frequency reduction, cpu hotplug and any other ways of reducing temperature. An ACPI version of this already exists(drivers/acpi/processor_thermal.c). This will be useful for platforms using the generic thermal interface and not the ACPI interface. If you want this support, you should say Y here.
