Since GT frequency is not obtained from MSRs, another function called GetGTFrequency() will provide this data. An MSR’s function, which the API obtains from GetMsrFunc(), determines the amount and meaning of data returned from GetPowerData() as described in Table 1. GetPowerData() is called for each sampled MSR and provides the relevant data from that MSR. The MSR ID is used to acquire data for a specific MSR using GetMsrName(),GetMsrFunc() and GetPowerData() functions. MSRs are given an ID from 0 to n-1, where n is the number returned by GetNumMsrs(). ReadSample() obtains the number of sampled MSRs from GetNumMsrs(). The ReadSample()function is used to read samples.

Here, the loading of the driver takes place. This library must be initialized at the start of the program by calling IntelEnergyLibInitialize(). 3.2 OverviewĪs the primary API, developers may use Intel® Power Gadget’s EnergyLib32.dll for 32-bit applications or EnergyLib64.dll for 64-bit applications. Although the Intel® Power Gadget API can be used with a sampling frequency ranging from 1 to 1000 milliseconds, the optimal sampling frequency of 100 milliseconds is the default selection on the GUI and is recommended for application developers. Higher the frequency, greater will be the accuracy of the data but poorer will be the performance of the system. Data is acquired from specific MSRs at a fixed sampling frequency.

Sample code called “” to use Intel® Power Gadget’s DLL is available for download at the bottom of this page 3.API of Intel® Power Gadget 3.1 Concept of Samplingįor a good understanding of the API, it is essential to be familiar with the concept of sampling.

IPG_Dir: Contains directory in which the DLLs (EnergyLib64.dll used for 64-bit applications and EnergyLib32.dll used for 32-bit applications) were installed.ĭevelopers may utilize the DLL for their 32-bit or 64-bit applications.

IPG_Ver: Contains version of Intel® Power Gadget being installed.

The installer sets two environment variables on installation: Microsoft Visual C++ 2010 SP1 Redistributable Package will also automatically get installed if not yet installed.įor more information on system requirements and installation, please visit Intel® Power Gadget page 2.Developers’ Tools Net Framework 4 will automatically be downloaded from the Microsoft website if not yet installed in your system.

For more details on the API, please refer to subsequent sections. The DLL serves as a C++ Application Programming Interface (API). This data can be viewed on a Graphical User Interface (GUI) and/or logged for a required duration of time.ĭevelopers may use this data to create their own application by exploiting the Dynamic-Link Library (DLL) used by the Intel® Power Gadget. The supported MSRs are correlated with three MSR functions as described in Table 1. The PROCHOT feature is available only in 3rd Generation Intel® Core™ processors or later. The data is obtained from the Model Specific Registers (MSRs) and energy counters that are available only in 2nd Generation Intel® Core™ or later processors.
