The power capping sysfs interface allows kernel subsystems to expose power
|
||
|
|
capping settings to user space in a consistent way. Usually, it consists
|
||
|
|
of multiple control types that determine which settings may be exposed and
|
||
|
|
power zones representing parts of the system that can be subject to power
|
||
|
|
capping.

This enables support for the Intel Running Average Power Limit (RAPL)
|
||
|
|
technology which allows power limits to be enforced and monitored on
|
||
|
|
modern Intel processors (Sandy Bridge and later).
|
||
|
|
|
||
|
|
In RAPL, the platform level settings are divided into domains for
|
||
|
|
fine grained control. These domains include processor package, DRAM
|
||
|
|
controller, CPU core (Power Plance 0), graphics uncore (Power Plane
|

1), etc.

This enables support for the idle injection framework. It

provides a way to force idle periods on a set of specified

CPUs for power capping. Idle period can be injected
|

|
|
synchronously on a set of specified CPUs or alternatively
|
||
|
|
on a per CPU basis.
