macOS Native Discrete GPU Power Management

[bogdanw]

means everything works ??
At me AppleGraphicsPowerManagement.kext the original changed there is registered Vendor & Device mine, such should not be probably ??

I have no idea, you should wait for toleda's answer.

Ok

What happened?

Toleda, that's what I did, is that right? I set my Vendor & Device values!

hat's what I did, is that right?

Post #48 shows you edited the Mac-AMD property for the device-id, incorrect.
Post #68 shows you edited the Mac-Nvidia property for the device-id, correct.
Remove either GFX0 or 10de0fc6 as they are the same.

And what better to delete GFX0 or Device? And I HAVE the ORIGINAL AppleGraphicsPowerManagement.kext also replaced the values under my Vendor! It is better to leave this or replace to the original??

In your case, GFX0 supports a Nvidia graphics card upgrade without an additional edit.
Device-id is specific to the installed graphics and requires an edit if replaced.

And I HAVE the ORIGINAL AppleGraphicsPowerManagement.kext also replaced the values under my Vendor!

The edit to the ORIGINAL kext will disappear in a subsequent software update, disabling GPU PM. The dGPU.kext survives Software Updates.

Ok. I delete GFX0.What can you say about that?

Hi @toleda For my Skylake build the wheels have fallen off because I am unable to configure AGPM so that Heuristic/ID displays 0x4. I cannot get it to display anything else but 0xffffffff therefore no PM for discreet GTX-970.
I tried to add AppleGraphicsPowerManagement.kext support in accordance with your instructions under heading 3 of the OP. - dAGPM.kext injector, but without success.
CPU and IGPU PM is working very well, at least what I could determine.
I specifically checked IGPU PM with iStatMenus while streaming an HD video to an AppleTV4-The framebuffer actually does the job quite well pushing up to 30 fps at around 500 mhz - varying - with the CPU idling powerwise.
Please refer to the contents of the attached "Working CPU and IGPU PM.zip" folder

With or without the dAGPM.kext Heuristic remains at 0xfffffff

High Sierra 10.13.
GA-Z170X-UD3 rev.1.0
Bios F23g
i7600K
GTX-970
Sysdef 17.1

To provide an ioreg Baseline I would basically have to undo the CPU and IGPU PM configuration, which I will do if you really want that.
I therefore provide an ioreg without dAGPM.kext in Clover/kexts/other as Baseline, and an ioreg with dAGPM.kext in Clover/Kexts/other.

All files attached.

Thank you for helping me on this one as well.

No IOReg attached, no idea

No suggestions for the GVA errors
