help
- This driver uses ACPI INT3403 device objects. If present, it will
- register each INT3403 thermal sensor as a thermal zone.
+ Newer laptops and tablets that use ACPI may have thermal sensors
+ outside the core CPU/SOC for thermal safety reasons. These
+ temperature sensors are also exposed for the OS to use via the so
+ called INT3403 ACPI object. This driver will, on devices that have
+ such sensors, expose the temperature information from these sensors
+ to userspace via the normal thermal framework. This means that a wide
+ range of applications and GUI widgets can show this information to
+ the user or use this information for making decisions. For example,
+ the Intel Thermal Daemon can use this information to allow the user
+ to select his laptop to run without turning on the fans.
