4 The power capping framework provides a consistent interface between the kernel
5 and the user space that allows power capping drivers to expose the settings to
10 The framework exposes power capping devices to user space via sysfs in the
12 'control types', which correspond to different methods of power capping.  For
15 corresponds to the use of idle injection for controlling power.
18 monitored using the power capping method determined by the control type the
19 given zone belongs to. They each contain attributes for monitoring power, as
20 well as controls represented in the form of power constraints.  If the parts of
21 the system represented by different power zones are hierarchical (that is, one
22 bigger part consists of multiple smaller parts that each have their own power
23 controls), those power zones may also be organized in a hierarchy with one
24 parent power zone containing multiple subzones and so on to reflect the power
25 control topology of the system.  In that case, it is possible to apply power
26 capping to a set of devices together using the parent power zone and if more

148 control type called intel-rapl which contains two power zones, intel-rapl:0 and
149 intel-rapl:1, representing CPU packages.  Each of these power zones contains

157 power value, there is no power_uw attribute.
159 In addition to that, each power zone contains a name attribute, allowing the

190 power_uw (ro): Current power in micro watts.
192 max_power_range_uw (ro): Range of the above power value in micro-watts.
194 name (ro): Name of this power zone.
196 It is possible that some domains have both power ranges and energy counter ranges;
208 constraint_X_max_power_uw(ro): Maximum allowed power in micro watts.
210 constraint_X_min_power_uw(ro): Minimum allowed power in micro watts.
228 Call powercap_register_zone() to register a power zone (under a given
229 control type), either as a top-level power zone or as a subzone of another
230 power zone registered earlier.
