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 20 tristate "Intel RAPL Support" 21 depends on X86 && IOSF_MBI 22 default n 23 ---help--- 24 This enables support for the Intel Running Average Power Limit (RAPL) 25 technology which allows power limits to be enforced and monitored on 26 modern Intel processors (Sandy Bridge and later). 27 28 In RAPL, the platform level settings are divided into domains for 29 fine grained control.

Idle period can be injected 41 synchronously on a set of specified CPUs or alternatively 42 on a per CPU basis. 43endif 44
