help
|
|
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.

help
|
|
This enables support for the Intel Running Average Power Limit (RAPL)
|
|
technology via MSR interface, 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 Plane 0), graphics uncore (Power Plane
|
|
1), etc.

help
|

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.

This enables support for the ARM Powercap based on ARM SCMI

ARM SCMI Powercap protocol allows power limits to be enforced

and monitored against the SCMI Powercap domains advertised as
|
|
available by the SCMI platform firmware.
|

|
|
When compiled as module it will be called arm_scmi_powercap.ko.
