Split intel_rapl.c to intel_rapl_common.c and intel_rapl_msr.c, where intel_rapl_common.c contains the common code that can be used by both MSR and MMIO interface. intel_rapl_msr.c contains the implementation of RAPL MSR interface.

|
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 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 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.
