Pavo 1,036 Posted January 6 (edited) 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.

SavageAUS 672 Posted January 6 Good work,Any chance of a list of cards this is helpful with or is it helpful for anyone with a dGPU?Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
Pavo 1,036 Posted January 6 Good work, Any chance of a list of cards this is helpful with or is it helpful for anyone with a dGPU? Sent from my iPhone using Tapatalk As of right now it will only work with any natively supported dGPU Share this post Link to post Share on other sites
xtddd 79 Posted January 6 is it conflict with whatevergreen.kext? Share this post Link to post Share on other sites
SavageAUS 672 Posted January 6 (edited) 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? Edited January 6 by SavageAUS Share this post Link to post Share on other sites

mitch_de 294 Posted January 6 Its only for Mojave and not High Sierra? EDIT: I build it for HS - works (generates the .kext - untested the .kext) AGPMInjector_HS.zip Share this post Link to post Share on other sites
Pavo 1,036 Posted January 6 IT displays below without generating this kext..what is difference? 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. 2 nmano and xtddd reacted to this Share this post Link to post Share on other sites

Pavo 1,036 Posted January 6 Its only for Mojave and not High Sierra? 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. Share this post Link to post Share on other sites
Pavo 1,036 Posted January 6 hi,pavo,,,so in my case ,,there is no need to use this kext..right? 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. 1 xtddd reacted to this Share this post Link to post Share on other sites
mitch_de 294 Posted January 6 No, your App shows error if started in HS. I buld it for 10.13 Deployment (uploaded HS Version few post before). Share this post Link to post Share on other sites

mitch_de 294 Posted January 6 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. Share this post Link to post Share on other sites
mitch_de 294 Posted January 6 in my rig,,the control-id is 11... 0x11 = HEX value = 17 decimal 18 dec = 0x12 Share this post Link to post Share on other sites
Pavo 1,036 Posted January 6 (edited) in my rig,,the control-id is 11... No, your control-id is 17 because hex converted to decimal is 0x11 hex = 17 decimal, 0x12 hex = 18 decimal Edited January 6 by Pavo 1 xtddd reacted to this Share this post Link to post Share on other sites
Pavo 1,036 Posted January 6 0x11 = HEX value = 18 decimal You mean 17 decimal 1 xtddd reacted to this Share this post Link to post Share on other sites
xtddd 79 Posted January 6 (edited) You mean 17 decimal that is right..it is 17....i also need this kext Edited January 6 by xtddd Share this post Link to post Share on other sites
xtddd 79 Posted January 6 You mean 17 decimal i have added this kext.now it display 12 hex....but the IGPU dont display. Share this post Link to post Share on other sites
mitch_de 294 Posted January 6 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 1 xtddd reacted to this Share this post Link to post Share on other sites

I will look into adding support for iGPU in the future. 1 xtddd reacted to this Share this post Link to post Share on other sites
