SMCAMDProcessor.kext

Shaneee · Apr 28, 2020

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.

Installation
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.

Download the kext(s) and application from Release page
Add AMDRyzenCPUPowerManagement.kext to kext folder of your bootloader.
Edit your bootloader's config file to make sure the kext is enabled.
If you're using VirtualSMC you can also load SMCAMDProcessor.kext to publish sensor data.
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.

Features

CPU power management for AMD 17h processors.
Supports for reading of temperature, energy and frequency data on AMD 17h Processors.
Manual switching of processor speed.
PState editing.

Hallo Shaneee,
would you please do me the favor and compile me the master? I would be very grateful for it because I just can't do it.

You need to include Lilu in the source folder, https://github.com/trulyspinach/SMCAMDProcessor/issues/33

Kokowski · May 2, 2020

Yes, you've already mentioned it, but i don't understand how to do it.

You'd be best asking trulyspinach then.

Kokowski · May 2, 2020

I've already asked him for further instructions, but no response.

Enkido · May 3, 2020

Open the project in Xcode, then drag Lilu.kext into the project navigator pane on the left. Xcode will then ask which targets to include it in, select them all and you should be able to compile any of the targets.

Aluveitie · May 3, 2020

You need VirtualSMC too to compile it.

I have all this installed in the correct order but dont get CPU temps in iStat, any ideas ?

iStats uses the SMBIOS and as far as I know does not yet work with MacPro7,1. You’d have to try with iMacPro1,1 instead.

Shaneee · May 3, 2020

You could also test with iStatistica. Not sure if it uses the same sensor info as iStats.

ftln · May 3, 2020

Hi, CPU temps do infact display with iStatistica, Thanks

Kokowski · May 4, 2020

@Enkido @Aluveitie I've tried it with lilu and virtualsmc, but the result always is, that only the Power Gadget will be compiled.

Aluveitie · May 4, 2020

@Kokowski try

Code:

xcodebuild -scheme SMCAMDProcessor -configuration Release
xcodebuild -scheme AMDRyzenCPUPowerManagement -configuration Release
xcodebuild -scheme "AMD Power Gadget" -configuration Release

Kokowski · May 4, 2020

Thanks for the advice @Aluveitie , but i don't really understand. Would you please take a look?

Aluveitie · May 4, 2020

I'm using the command line to build the final kexts, don't know too much about XCode myself.

Kokowski · May 4, 2020

Then what would be your commands for cloning over adding lilu and virtualsmc to building?

Aluveitie · May 4, 2020

Kokowski said:

That I did in XCode. I have look up later where I placed them exactly.

Aluveitie · May 4, 2020

Looks fine, you should be able to build with the commands I posted

Kokowski · May 5, 2020

@Aluveitie Doesn't work for me.
