macOS Project 2: I am making another kext for unsupported GPUs.

[welikeyou3000]

The GPU series this time is nVidia's Ampere! You have all been waiting on RTX GPUs with Metal Support and/or Mac support. For me though, this is a insane, time consuming, and brutal task!

Thank you!

Good luck! Sounds like an absolutely tremendous effort to get that going. Will you work on it in an open source setting?

Thanks! It will be my own project as a open source.

Did you write one before? I don't think i've ever seen anyone (that's not apple or nvidia) write a graphics driver for osx, there is zero documentation. The closest you can get is using the old macintosh 9 documentation for ndrv video drivers to write a basic framebuffer driver, which is apparently still loaded by osx.

ATI HD framebuffer driver (10.5/10.6) with source code

Put it into /S/L/E/ and rebuild the cache to test. It will not affect vanilla driver. Any injector will prevent this driver from loading since it works the same way as IONDRVSupport. [FAQ:] 1. get a blank or dark screen after boot, or the screen keep flashing In RadeonHD.kext/Contents/Info.plist,...

In fact native nvidia drivers used to be structured this way, they are architected as ndrv drivers somehow. However there was never a way to wire up hardware acceleration i believe, that entire part of osx is pretty undocumented, and what public information exists comes from various 0-days people have found poking and reversing pieces.
