That's great, I will test it on Ubuntu + Nouveau x86_64 and Batocera-Linux.

I'm not interested in Raspberry Pi. I see you have some commit in
RaspberryPi/Linux. Will this go to some Nouveau driver, so I can test it on
x86_64 machine? I have some basic experience compiling Linux kernel (nvidia
driver) from 10 years ago.

Nouveau is only marginally affected by this patch series. It could
leverage the work done here, but it's not part of it and I won't plan to
work on it.

The RaspberryPi is mentioned because it's the platform that will benefit
the most from it, and the main target of that series.

Scaling is not the way to go because I do this to not use scaling. I could
use 640x480 and scale 320x240 to that mode, right? That is what old
retrogaming laptop LCD screens do (you can even enable this in their BIOS).

More appropriate is to preserve pixel ratio and have some border. So you
mostly select the closest resolution and live with small border on the
edge. Then you can crop it on analog TV using real world dials :-)

I joined Nouveau developer list here. I don't know why we have like 40
email recipients here and now we discuss Raspberry.

Nouveau is marginally affected by it, so its mailing list is in Cc.
