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. | |
