/* Requests power off of dGPU in MacBookPro8,2/3 (TS2 hardware failure)
* Main goal is to ensure power draw from the dGPU is reduced as
* much as possible to simulate a hardware demux without actual
* hardware modifications.
*
* Notes:
* - SSDT must be used in conjuction with '_INI' to 'XINI' patch
* to reroute PCI0 initialization.
*
* - AMD drivers in macOS may still attempt to attach and kernel
* panic. Disable the dGPU with class-code/device-id spoof or
* with '-wegnoegpu'.
*
* - dGPU will reactivate with sleep-wake, additional process
* is needed to disable the dGPU.
* - ie. AMDGPUWakeHandler.kext for macOS
*

For MacBookPro8,2/3 users, it's very common for the dGPU to fail and

this option will simulate a demuxed enviroment allowing the dGPU to pull nearly
no power and have the iGPU handle all tasks including brightness control.
