Hey guys! I am having a little problem now with my iGPU on OC Big Sur. The iGPU, though being Comet Lake, is not UHD630, and is instead, according to daliansky's list of all GPUs, "Intel Comet Lake GT2" with device-id 0x9BC4, which is natively supported as per the WhateverGreen FAQ. Unfortunately there is no DVMT option in my BIOS, so I implemented a Framebuffer stolen patch in device properties as in my config. (I would really appreciate if some one could explain the stolen patch's mechanism for me so that I could know why I am doing this - e.g. does it have to do with VRAM). I've tried all ig-platform-ids, and none of them work. If I use an invalid one, I can boot into the system but with no acceleration (32MB VRAM). Otherwise it gets stuck on the Apple Icon + Progress Bar after the screen lightens up (probably due to the presence of the PNLF device) (in verbose, IOConsoleUsers: gIOScreenLock). I really want to know what is causing this problem and how to solve it.
Any help would be appreciated.
