DSDT edit for disabling iGPU
I've recently made some progress on this issue.
After editing AppleGraphicsPowerManagement.kext/Contents/Info.plist it seems to recognise the GPU.
The logs now say
instead of
previously.
Sleep and wake are still not working though.
Based on what I've managed to learn about the issue, I suspect that the sleep and wake sequence fails because it doesn't correctly handle the integrated and discrete GPUs.
So I want to change the DSDT to disable the iGPU and make sure that only the discrete GPU is used, but I'm not sure how to do that.
I have found some patches by RehabMan but they do the opposite: disable the Radeon discrete GPU in favour of the integrated GPU.
They are probably a good starting point but I need some help to figure out how to edit them.
