Amd power gadget mac os

Amd power gadget mac os

XNU kernel extension for power management and monitoring of AMD processors. Also comes with a plugin for VirtualSMC to export readings to other applications.

Please note that this release is at very initial stage of development, make sure you have a proper backup of your EFI folder and never run on any system that matters.

SMCAMDProcessor now comes in two separate binaries(kernel extensions):

• AMDRyzenCPUPowerManagement.kext for all power management features. This kext is also required if you would like to use AMD Power Gadget.
• SMCAMDProcessor.kext to publish readings to VirtualSMC, which enables macOS applications like iStat to display sensor data. This kext depends on AMDRyzenCPUPowerManagement.kext to collect sensor data, thus must be loaded after.

1. Download the kext(s) and application from Release page
2. Add AMDRyzenCPUPowerManagement.kext to kext folder of your bootloader.
3. Edit your bootloader’s config file to make sure the kext is enabled.
4. If you’re using VirtualSMC you can also load SMCAMDProcessor.kext to publish sensor data.
5. Bootloaders like OpenCore will link each kext in the order they present in config file, so make sure AMDRyzenCPUPowerManagement.kext comes before SMCAMDProcessor.kext as it serves as a dependency.

• CPU power management for AMD Zen processors.
• Supports for reading of temperature, energy and frequency data on AMD Zen Processors.
• Manual switching of processor speed.
• PState editing.

AMD Power Gadget

Since the release 0.3.1, you can now edit your CPU PState using AMD Power Tool.

To access PState editor:

1. Open AMD Power Tool
2. Go to ‘Speed’ tab
3. Click ‘Advanced Options’

Due to the amount of request an experimental feature for reading and overriding fan speed is out!

You can access this menu from menu bar «Open -> SMC Fans» or the button in Power Tool. Currently only a limited amount of SMC controllers are supported.

• Incorrect PState setting can potentially cause permanent damage to your computer hardware.
• For safety concern, this function was limited to root user only. You can either launch AMD Power Gadget with root user or use -amdpnopchk to disable this check.

If you like this project, please consider supporting it via:

Buy me a coffee(or a Zen 3 processsor 😝 ).

Opening up an issue if you encountered any problem or want to make suggestions.

or if you’re a coding person, feel free to submit any pull request or just DM me on Discord.

• aluveitie for various enhancements and fixes.
• mauricelos for IT86XXE SMC chip driver.
• necross2 for adding support to temperature sensor offset.
• Shaneee for the beautiful icon.

I am still fairly new to macOS kernel development, this software project was initally a hobby project, and it still is, to get some reading on my newly built AMD hackintosh computer.

With that being said, please bear with some of the spaghetti and not-idiomatic codes. Any criticism is much welcomed 🙂

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

Usages (Windows*)

Common use of Intel® Power Gadget is to monitor energy usage of the processor

• Provides processor power (Watts), temperature (Celsius) and frequency (MHz) in real-time via graph displayed in the GUI
• Let you log the power and frequency measurements and save it in a csv format.
• Double click on the desktop shortcut and the GUI will launch
• Drag to move the GUI.
• Right click the GUI and a pop-up menu will show up allowing you to choose options or close the application. Options have the following parameters. Click “Start Log” button in the GUI to start logging. Press the same button “Stop Log” to stop logging. While it’s logging, red label “REC” will blink in the power chart area.
• You can choose to add time-stamp to the log file name or not.
• You can choose the log file name.
• You can choose to resize the GUI from 100% to 300% by dragging the slider and testing the new size with the “Apply Size” button and accept the changes by pressing “Ok”.
• Screen Update Resolution lets you change how often the GUI is updated at runtime. This may range from 50 ms to 1000 ms. (Default set to 1000 ms)
• Log Sampling Resolution lets you change the logging sampling resolution ranging from 1 ms to 1000 ms. (Default set to 100 ms)
• In a multi-socket system, you can choose which package information to display in the GUI. The log will record all package information in a csv file.
• Click «Start Log» button in the GUI to start logging. Press the same button «Stop Log» to stop logging. While it’s logging, red label «REC» will blink in the power chart area

Using Intel® Power Gadget 3.0 in a Script

In order to start and stop the logging in a script, first launch the GUI as usual.

• At the beginning of the script, call «IntelPowerGadget.exe -start» and it will trigger the logging in the GUI.
• At the end of the script, call “IntelPowerGadget.exe -stop” and it will stop the logging.

The parameters for the log are based on the options set in the GUI.
