macOS Native CPU/IGPU Power Management

[RehabMan]

But what is the benefit of this method comparing to usual generated ssdt?

Benefit is that it is easier to apply, and not specific to a CPU.

It means, for example, you can apply this technique while running the installer (just put the SSDT-PluginType1.aml or SSDT-XCPM.aml at EFI/Clover/ACPI/patched).

It also means that with a fully hotpatched ACPI setup (beyond what is covered here), you can share EFI/Clover from one computer (same model/series) to another, as there will be no ACPI content specific to a particular CPU.

I choose the system definition Mac-A369DDC4E67F1C45 (iMac16,1). This is the one that I found gives me less obvious troubles so far. However I discovered that AGPM.kexts loads a profile for my iGPU that limits its max frequency to 900MHz, so I get less performance (significant for any iGPU) .

In
AppleGraphicsPowerManagement.kext Info.plist -> IOKitPersonalities -> AGPM -> Machines -> Mac-A369DDC4E67F1C45 -> IGPU
There's a setting that limits my iGPU turbo, not sure which one. So I replaced that IGPU object with another IGPU object from another machine (iMac17,1). Now my humble but significant turbo frequency at 1100MHz is back.

My question is how can I change that AGPM profile without editing the kext, using a clover patch or ssdt and without changing my system definition ?

how can I change that AGPM profile without editing the kext

Key issue, no native macOS Kaby Lake support currently.
Workaround, iMac17,1 (if AGPM works as expected).

Instead of patching the kext, create an injector kext that overrides the Info.plist content in AppleGraphicsPowerManagement.kext.

Good idea. That did the trick!.

Dunno if you want some sample data, I used https://www.tonymacx86.com/threads/skylake-hwp-enable.214915/

And then used yours and went from this to this

[vagvalas]

I followed the guide to the letter, but i ran to some probs => i've got some questions.
#1 I got an Intel i7 4790k
When i loaded AppleIntelInfo.kext a KP, is there any chance this to be fixed someHow so i can use the kext for extra info.

#2 My Cpu never goes to intel Frequency? Why, Should i generate (and install) a 2nd SSDT with Piker's Alpha Script?

Notes: I use Clover, on an Asus Hero VII - i7 4790k - 20Gb 1600mhz Ram.
