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. |

74 | This implements the generic cpu cooling mechanism through frequency | |

78 | and not the ACPI interface. | |
