Do I understand DAL3.jpg correctly that the macOS driver builds on top
of DAL Core?  I'm asking because the graphics drivers shipping with
macOS as well as on Apple's EFI Firmware Volume are closed source.

If the Linux community contributes to DC, I guess those contributions
can generally be assumed to be GPLv2 licensed.  Yet a future version
of the macOS driver would incorporate those contributions in the same
binary as their closed source OS-specific portion.

I don't quite see how that would be legal but maybe I'm missing
something.

Presumably the situation with the Windows driver is the same.

I guess you could maintain a separate branch sans community contributions
which would serve as a basis for closed source drivers, but not sure if
that is feasible given your resource constraints.

Thanks,

Lukas
