[Help Wanted] Load Apple's GuC Firmware

[tylernguyen]

Currently, loading Apple's Graphics Micro will lead to a boot hang, it seems to be incompatible with the machine's CPU and iGPU: UHD 620.

However, loading Apple's GuC is necessary to achieve better cpu usage and power management.

I honestly have no idea how to tackle this problem but will leave this issue ticket here for discussion a placeholder for reference materials.

Feel free to chime in if you have any idea on the matter.

This looks promising. I will try on my laptop. It could solve DRM?

DRM is an entirely different matter. Loading Apple's GUC is firstly for iGPU power management and native macOS handling of the iGPU.
