Motivated by the pre-review process for i915 gem/gt features, but
probably useful in general for complex stuff.

I understand the motivation here so I didn't commented earlier, but looking now,
I'm wondering that this section will polute the official doc...

We already have this problem between documentation meant for kernel driver
developers and documentation meant for userspace developers around uapi
and all that. "who is the audience here" is very ill-defined for our
current set of docs in Documentation/gpu :-(

So I agree with you, but I also don't think this will make things worse.

you have a point...

another thing that I don't like is the overhead, but otoh it forces us to
write more docs...

with all the pros and cons understood, let's move on...

Side note: I feel like we could have better lines of communication
between kernel devs and user-space devs. The new uAPI requirements seem
to be a high barrier to entry for kernel devs. However sometimes
user-space devs might be interested in helping out with the user-space
part…

Maybe it would be good to CC e.g. wayland-devel for new RFCs, so that
user-space devs can jump in if they're interested. And also provide
feedback, since new uAPI is hard to spot in the sea of messages in
dri-devel.

That's a good suggestion.  CCing wayland-dev or mesa-dev, as
appropriate, with such docs patches sounds like a good idea.  I'm not
sure where we would put that in here but it would be good to call out.

I'll add a suggestion to that extend, it's a good one.

Let's give it a try, I do like the future ideas of doing things with
gitlab issues as well.
