blackgate / amdgpuwakehandler Goto Github PK

Hello @blackgate

many thanks for the repo!

My question is about the fork (https://github.com/timpalpant/NVDAGPUWakeHandler), but for some reason I could not open an issue there, so let me ask you - perhaps you could guide me. As far as I can tell, the core functionality was not changed by the fork.

I'm trying to build the project for Mojave (10.14.6) on MacBook (Early 2013 in my case).

So far I changed only OSBundleLibraries versions (to 18.7) in Info.plist and MACOSX_DEPLOYMENT_TARGET = 10.14 in Build Settings. But the resulting kext failed to be loaded:

NVDAGPUWakeHandler.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).

kextutil give some details

(kernel) kxld[test.NVDAGPUWakeHandler]: The super class vtable '__ZTV9IOService' for vtable '__ZTV18NVDAGPUWakeHandler' is out of date. Make sure your kext has been built against the correct headers.
(kernel) Can't load kext test.NVDAGPUWakeHandler - link failed.
(kernel) Failed to load executable for kext test.NVDAGPUWakeHandler.

Could you suggest what could cause the error and how to fix it?

Hi,

I came across your great work and was talking to the dev team of OCLP (Open Core Legacy Patcher) and wonder if this can be included as part of it?

Here is the thread where we discussed this:

Hi,

first of all: Thanks for your effort in keeping this old Laptop running 👍

Backstory: Back when I discovered on how to get this Macbook working again, I disabled the GPU using the NVRAM variables, deleted the AMDRadeonX3000.kext from the Extensions Folder and loaded a old version of "AMDRadeonX3000.kext" with "sudo kextload /path/to/AMDRadeonX3000.kext". This worked fairly well, but having to load the kext every time I open up my Laptop got annoying.
Additionally, I was behind on updates. So I went ahead and updated from 10.12.4 to 10.12.6 and installed grub.

Now I run your kext that I built using Xcode and according to it's logs, it's disabling the GPU.

But now my macbook idles with 30W power draw according to Coconut Battery.

When I go ahead and load AMDRadeonX3000.kext version 1.51.8 that was extracted from some osx setup (not 100% sure, might have to digg through the Macrumors thread) the Macbook only draws 10-12W while writing this.

Do you have any idea whats causing this?
