Introduction

Intel® Power Gadget is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 10th Generation Intel® Core™ processors). Intel® Atom™ processors are not supported. It is supported on Windows* and macOS* and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. With this release, we are providing functionality to evaluate power information on various platforms including notebooks, desktops and servers. Windows 7* and 32-bit versions of the Intel® Power Gadget for Windows* has ceased development from 3.0.7. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported.

Background

Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the platform along with third party equipment. The motivation for the tool was to assist end-users, ISV's, OEM's, developers, and others interested in a more precise estimation of power from a software level without any H/W instrumentation.

New Features

In version 3.0 there are additional features that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code. The multi-socket support essentially evaluates the Energy MSR on a per-socket basis and provides an estimate of power draw per socket. The API layer is a set of libraries and dlls that can be called and offers the flexibility to build the tool within code sections of an application. Latest release also includes support for Windows 10*.

Brief Description (Windows*)

Intel® Power Gadget 3.5 consists of the following components. Set of driver and libraries which access and post process the processor energy counter to calculate the power usage in Watts, temperate in Celsius and frequency in GHz (default install directory will be ~Program FilesIntelPower Gadget 3.5). A command line version of the tool (PowerLog3.0.exe) is also included

Using the Intel® Power Gadget API on Mac OS X*

Intel® Power Gadget for Mac* is a GUI application that provides real-time data on processor frequency and estimated processor power, and can log frequency, power, energy, and temperature data over time. Intel® Power Gadget also provides a C Application Programming Interface (API) for accessing this power and frequency data in your program. Intel® Power Gadget is also available for Windows* and Linux*. Intel® Power Gadget and the API are only supported on 2nd generation and later Intel® Core processors, because previous processors do not support the necessary power Model Specific Registers (MSRs).

Intro to the Intel® Power Gadget API

The Intel® Power Gadget API is a framework (IntelPowerGadget .framework) that provides a C interface for reading current estimated processor power, current processor frequency, base frequency, thermal design power (TDP), current temperature, maximum temperature, timestamps, and elapsed time. It also provides logging functionality.

What You Need

To use the API you'll need the Intel® Power Gadget for Mac* driver and framework. These are included in the Intel® Power Gadget installer, or as a standalone API installer. The driver is installed to /System/Library/Extensions/EnergyDriver.kext, and the framework is installed to /Library/Frameworks/IntelPowerGadget.framework.

To link with the Intel® Power Gadget API you simply need to include
–framework IntelPowerGadget in your link command.

Using the Intel® Power Gadget API

To begin you must initialize the library by calling IntelEnergyLibInitialize.

The most common use of the Intel® Power Gadget API is to read samples with ReadSample. The API supports sampling of specific Model Specific Registers (MSRs). Meta data on the sampled MSRs can be queried with GetNumMsrs, GetMsrName, and GetMsrFunc. GetNumMsrs returns the number of sampled MSRs; MSRs are given an ID from 0 to n-1, where n is the number returned by GetNumMsrs. The MSR ID is used to get data for a specific MSR with functions GetPowerData, GetMsrName, and GetMsrFunc.

Calling GetPowerData for each sampled MSR will provide you with the relevant data from that MSR. An MSR's function (from GetMsrFunc) determines the amount and meaning of data returned from GetPowerData. MSRs with function 0 (frequency) return 1 result, which represents the frequency in megahertz. MSRs with function 1 (power) return 3 results, which represent the average power in watts, cumulative energy in Joules, and cumulative energy in milliwatt-hours. MSRs with function 2 (temperature) return 1 result, which represents the temperature in degrees Celsius. The Intel® Power Gadget API currently supports sampling with the following MSRs: processor frequency, estimated processor power, and package temperature. The currently supported MSR functions are: frequency (0), power (1), temperature (2).

ReadSample also reads the system time and Time Stamp Counter (TSC) at the time the sample is read. These values are available via GetSysTime and GetRDTSC; the time interval between samples is available (in seconds) via GetTimeInterval. Note that you must call ReadSample prior to calling GetPowerData, GetRDTSC, and GetTimeInterval, and that you must call ReadSample twice before calling GetTimeInterval and before getting power data (as opposed to frequency or temperature data) from GetPowerData, as they are computed using the difference between two samples.

The Intel® Power Gadget API also supports reading generic MSRs with ReadMSR, which returns the raw data from the MSR. However, note that specifying an invalid MSR address can crash your system and could potentially corrupt it. There is no method to determine if an MSR address is valid. The API supports reading common individual MSRs without having to specify the MSR address or read an entire sample; the supported functions are: GetIAFrequency, GetMaxTemperature, GetTemperature, and GetTDP.

The sample data from ReadSample can be logged to a file. Logging can be enabled at any time by calling StartLog, and subsequently disabled by calling StopLog. Note that the logged data isn't written until StopLog is called. Both StartLog and StopLog cause an internal call to ReadSample.

Sampling Considerations

The frequency at which you read samples may have an impact on the accuracy of data. The instantaneous processor frequency can change significantly from moment to moment. Frequency data may be more meaningful if you sample often and average the frequency samples over time. The processor power is calculated by taking the difference between two samples, thus a shorter interval between samples will result in more fine-grained power data. However, the frequency at which you read samples may also impact the performance of the system. Using a very short frequency (e.g. less than 20 milliseconds) may result in significant overhead, and may also increase the power consumption of the system, both of which may reduce the usefulness of the data. The Intel® Power Gadget application uses a default sampling frequency of 50 milliseconds, and updates the GUI with averaged frequency and power data every second.
