AGPM Injector kext generator app!!

[Pavo 1,045]

I would like to introduce you to a new app I just go done creating.

AGPM Injector, its an app to generate an injector kext for Apple Graphics Power Management for discrete GPUs.

Good work,
Any chance of a list of cards this is helpful with or is it helpful for anyone with a dGPU?

As of right now it will only work with any natively supported dGPU

thank you

is it conflict with whatevergreen.kext?

[SavageAUS 672]

And what can we do if X86PlatformPlugin is not loaded?

 

Edit: Never mind, fixed. What should we look for after creating the kext?

Is EFI folder fine or S/L/E?

Whatevergreen handles AGDP not AGPM.

I have not tested it in S/L/E or L/E, only EFI/Clover/kexts/Other

IT displays below without generating this kext..what is difference?

[mitch_de 294]

Its only for Mojave and not High Sierra?

EDIT: I build it for HS - works (generates the .kext - untested the .kext)

AGPM can work by itself if you are using the correct SMBIOS and GPU combination. Most the time the AGPM settings are wrong though because most GPUs in real Macs are mobile GPUs. This AGPM kext injector generator app will generate a AGPM injector kext with the correct settings for discrete GPUs. Right now it only supports what SMBIOS AGPM supports natively but if there are use cases out there that the SMBIOS isn't listed in the app, I could use that feedback to update the app.

hi,pavo,,,so in my case ,,there is no need to use this kext..right?

It is actually OS version independent, the app will parse the System/Library/Extensions/AppleGraphicsPowerManagement.kext on the system you are running the app on and generate a injector kext for that version of the system. I have only tested it for HS and Mojave but theoretically it could work for older OSes also.

Depends..... From your sig I see you are using 7700k CPU which means you should be using iMac18,3 SMBIOS. The AGPM settings for that SMBIOS have settings for both iGPU and GFX0. But the control-id for the GFX0 device is 17, which is for mobile GPUs. discrete GPUs should be using control-id 18. So in theory yes you should use this app to generate a injector kext to change the AGPM settings to use the right control-id.

[mitch_de 294]

No, your App shows error if started in HS. I buld it for 10.13 Deployment (uploaded HS Version  few post before).

Will look into that, thanks for the feedback.

in my rig,,the control-id is 11...

[mitch_de 294]

For my iMac 13,2 the AppleGraphics... is same in HS und Mojave.

Left of first pic is HS , right is 10.4-

 

This App would change that  into , second pic.

0x11 = HEX value = 17 decimal

18 dec = 0x12

No, your control-id is 17 because hex converted to decimal is 0x11 hex = 17 decimal, 0x12 hex = 18 decimal

You mean 17 decimal

[xtddd 79]

 

You mean 17 decimal

that is right..it is 17....i also need this kext

i have added this kext.now it display 12 hex....but the IGPU dont display.

[mitch_de 294]

I tested now the generated .kext with my iMac 13,2.

kext seems only add / change the GFX0 AGPM part.

BUG: It deletes the IGPU AGPM part from the orig. .plist.

 

Pic  left side shows AGPM after using the kext = IGPU part is missing/deleted, rigth side before using the kext (original AppleGra..)

Workaround: I copied the IGPU part (for my iMac13,2 ) into the AGPM.kext

The kext injector is only for dGPUs for right now. I will look into adding support for iGPU in the future.
