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 depends on PCI 22 select IOSF_MBI 23 24config INTEL_RAPL 25 tristate "Intel RAPL Support via MSR Interface" 26 depends on X86 && PCI 27 select INTEL_RAPL_CORE 28 help 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). 32 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 36 1), etc. 37 38config INTEL_RAPL_TPMI 39 tristate "Intel RAPL Support via TPMI Interface" 40 depends on X86 41 depends on INTEL_TPMI 42 select INTEL_RAPL_CORE 43 help 44 This enables support for the Intel Running Average Power Limit (RAPL) 45 technology via TPMI interface, which allows power limits to be enforced 46 and monitored. 47 48 In RAPL, the platform level settings are divided into domains for 49 fine grained control.

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 61 on a per CPU basis. 62 63config ARM_SCMI_POWERCAP 64 tristate "ARM SCMI Powercap driver" 65 depends on ARM_SCMI_PROTOCOL 66 help 67 This enables support for the ARM Powercap based on ARM SCMI 68 Powercap protocol. 69 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. 73 74 When compiled as module it will be called arm_scmi_powercap.ko. 75 76config DTPM 77 bool "Power capping for Dynamic Thermal Power Management (EXPERIMENTAL)" 78 depends on OF 79 help 80 This enables support for the power capping for the dynamic 81 thermal power management userspace engine. 82 83config DTPM_CPU 84 bool "Add CPU power capping based on the energy model" 85 depends on DTPM && ENERGY_MODEL 86 help 87 This enables support for CPU power limitation based on 88 energy model. 89 90config DTPM_DEVFREQ 91 bool "Add device power capping based on the energy model" 92 depends on DTPM && ENERGY_MODEL 93 help 94 This enables support for device power limitation based on 95 energy model. 96endif 97
