| 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 |
