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. 14 15 If you want this code to be compiled in, say Y here. 16 17if POWERCAP 18# Client driver configurations go here. 19config INTEL_RAPL_CORE 20 tristate 21 22config INTEL_RAPL 23 tristate "Intel RAPL Support via MSR Interface" 24 depends on X86 && IOSF_MBI 25 select INTEL_RAPL_CORE 26 help 27 This enables support for the Intel Running Average Power Limit (RAPL) 28 technology via MSR interface, which allows power limits to be enforced 29 and monitored on modern Intel processors (Sandy Bridge and later). 30 31 In RAPL, the platform level settings are divided into domains for 32 fine grained control. These domains include processor package, DRAM 33 controller, CPU core (Power Plane 0), graphics uncore (Power Plane 34 1), etc. 35 36config IDLE_INJECT 37 bool "Idle injection framework" 38 depends on CPU_IDLE 39 default n 40 help 41 This enables support for the idle injection framework. It 42 provides a way to force idle periods on a set of specified 43 CPUs for power capping. Idle period can be injected 44 synchronously on a set of specified CPUs or alternatively 45 on a per CPU basis. 46 47config ARM_SCMI_POWERCAP 48 tristate "ARM SCMI Powercap driver" 49 depends on ARM_SCMI_PROTOCOL 50 help 51 This enables support for the ARM Powercap based on ARM SCMI 52 Powercap protocol. 53 54 ARM SCMI Powercap protocol allows power limits to be enforced 55 and monitored against the SCMI Powercap domains advertised as 56 available by the SCMI platform firmware. 57 58 When compiled as module it will be called arm_scmi_powercap.ko. 59 60config DTPM 61 bool "Power capping for Dynamic Thermal Power Management (EXPERIMENTAL)" 62 depends on OF 63 help 64 This enables support for the power capping for the dynamic 65 thermal power management userspace engine. 66 67config DTPM_CPU 68 bool "Add CPU power capping based on the energy model" 69 depends on DTPM && ENERGY_MODEL 70 help 71 This enables support for CPU power limitation based on 72 energy model. 73 74config DTPM_DEVFREQ 75 bool "Add device power capping based on the energy model" 76 depends on DTPM && ENERGY_MODEL 77 help 78 This enables support for device power limitation based on 79 energy model. 80endif 81
