I'm ok with the files moving if the dri developers agree with it. It's
up to them, not me.

On one hand I'm happy anytime someone volunteers to help out.

On the other hand ... why does it have to be resurrecting fbdev?
There's an entire community of people who really know graphics and
display and spent considerable amount of effort on creating useful and
documented helpers for pretty much anything you might ever want to do.
And somehow we have to go back to typing out things the hard way, with
full verbosity, for an uapi that distros are abandoning (e.g. even for
sdl the direction is to run it on top of drm with a compat layer,
afaiui fedora is completely ditching any userspace that still even
uses /dev/fb/0). And yes I know there's still some gaps in drm,
largely for display features which were really en vogue about 20 years
ago. And we're happy to add that support, if someone who still has
such hardware can put in the little bit of work needed ...

I don't get this.

You are describing a transitioning over to DRM - which is Ok.
But on that way there is no need to ignore, deny or even kill usage scenarios
which are different compared to your usage scenarios (e.g. embedded devices,
old platforms, slow devices, slow busses, no 3D hardware features,
low-color devices, ...).

And none of those examples is out-ruled by DRM. In fact we do support devices that fall in those categories.

This is last week's discussion all over again.

Best regards
Thomas
