7 bool "Generic powercap sysfs driver"
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
15 If you want this code to be compiled in, say Y here.

19 config INTEL_RAPL_CORE
25 tristate "Intel RAPL Support via MSR Interface"
27 select INTEL_RAPL_CORE
29 This enables support for the Intel Running Average Power Limit (RAPL)
30 technology via MSR interface, which allows power limits to be enforced
31 and monitored on modern Intel processors (Sandy Bridge and later).
33 In RAPL, the platform level settings are divided into domains for
34 fine grained control. These domains include processor package, DRAM
35 controller, CPU core (Power Plane 0), graphics uncore (Power Plane
38 config INTEL_RAPL_TPMI
39 tristate "Intel RAPL Support via TPMI Interface"
42 select INTEL_RAPL_CORE
44 This enables support for the Intel Running Average Power Limit (RAPL)
45 technology via TPMI interface, which allows power limits to be enforced
48 In RAPL, the platform level settings are divided into domains for
49 fine grained control. These domains include processor package, DRAM
50 controller, platform, etc.
53 bool "Idle injection framework"
57 This enables support for the idle injection framework. It
58 provides a way to force idle periods on a set of specified
59 CPUs for power capping. Idle period can be injected
60 synchronously on a set of specified CPUs or alternatively
63 config ARM_SCMI_POWERCAP
64 tristate "ARM SCMI Powercap driver"
65 depends on ARM_SCMI_PROTOCOL
67 This enables support for the ARM Powercap based on ARM SCMI
70 ARM SCMI Powercap protocol allows power limits to be enforced
71 and monitored against the SCMI Powercap domains advertised as
72 available by the SCMI platform firmware.
74 When compiled as module it will be called arm_scmi_powercap.ko.
77 bool "Power capping for Dynamic Thermal Power Management (EXPERIMENTAL)"
80 This enables support for the power capping for the dynamic
81 thermal power management userspace engine.
84 bool "Add CPU power capping based on the energy model"
85 depends on DTPM && ENERGY_MODEL
87 This enables support for CPU power limitation based on
91 bool "Add device power capping based on the energy model"
92 depends on DTPM && ENERGY_MODEL
94 This enables support for device power limitation based on
