0007 bool "Generic powercap sysfs driver"
0008 help
0009 The power capping sysfs interface allows kernel subsystems to expose power
0010 capping settings to user space in a consistent way. Usually, it consists
0011 of multiple control types that determine which settings may be exposed and
0012 power zones representing parts of the system that can be subject to power
0013 capping.

0027 This enables support for the Intel Running Average Power Limit (RAPL)
0028 technology via MSR interface, which allows power limits to be enforced
0029 and monitored on modern Intel processors (Sandy Bridge and later).

0031 In RAPL, the platform level settings are divided into domains for
0032 fine grained control. These domains include processor package, DRAM
0033 controller, CPU core (Power Plane 0), graphics uncore (Power Plane
0034 1), etc.

0041 This enables support for the idle injection framework. It
0042 provides a way to force idle periods on a set of specified
0043 CPUs for power capping. Idle period can be injected
0044 synchronously on a set of specified CPUs or alternatively
0045 on a per CPU basis.
