203d3d4a ZR |
7 | help |
8 | Generic Thermal Sysfs driver offers a generic mechanism for | |
9 | thermal management. Usually it's made up of one or more thermal | |
10 | zone and cooling device. | |
543a9561 | 11 | Each thermal zone contains its own temperature, trip points, |
203d3d4a ZR |
12 | cooling devices. |
13 | All platforms with ACPI thermal support can use this driver. | |
63c4ec90 | 14 | If you want this support, you should say Y or M here. |

23 | help |
24 | In case a sensor is registered with the thermal | |
25 | framework, this option will also register it | |
26 | as a hwmon. The sensor will then have the common | |
27 | hwmon sysfs interface. | |
28 | ||
29 | Say 'Y' here if you want all thermal sensors to | |
30 | have hwmon sysfs interface too. | |

218 | such sensors, expose the temperature information from these sensors | |
219 | to userspace via the normal thermal framework. This means that a wide | |
220 | range of applications and GUI widgets can show this information to | |
221 | the user or use this information for making decisions. For example, | |
222 | the Intel Thermal Daemon can use this information to allow the user | |
