I confirm there's lots of documentation (and even more code ;-),
which is always great!
But both are intimidating to me, and most of the documentation covers
features I'm not interested in, as they're only applicable to fancy
modern truecolor 3D-capable multi-buffer and multi-head hardware, while
what I am looking for is usually not documented.  E.g. I had a hard
time to discover how color look-up tables work (gamma_{store,size}!),
as this is not covered in https://docs.kernel.org/gpu/index.html,
and none of the tinydrm drivers support CLUT modes.

Gr{oetje,eeting}s,

                        Geert

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
