8 | help | |
9 | The power capping sysfs interface allows kernel subsystems to expose power | |
10 | capping settings to user space in a consistent way. Usually, it consists | |
11 | of multiple control types that determine which settings may be exposed and | |
12 | power zones representing parts of the system that can be subject to power | |
13 | capping. | |
