I noticed this article:
https://www.arcanoae.com/arca-noae-licenses-snap-graphics-os2-code/ from 2015
It do not remember seeing, a lot of use of this source code to expand the drivers to newer chips sets, instead more of a focus on vesa as a write once, run anywhere solution.
Just curious as to what happened/how that works, as I remember the early days of graphics chips having 100's of pages of manual explaining how to program them, then came CGA/Hercules - again with lots of, even bigger manuals explaining how to program them, then EGA - with even bigger books, then finally, I don't own a copy, but one really thick book on programming the 'VGA' chip.
Now, I don't know how programmers learn about the capabilities of various graphics chips, which continue to develop at a breakneck pace, both Nvidia, Intel and AMD.
