It's a fairly interesting idea I hadn't thought of.
My limited experience with all the graphics protocols and their history
means I have had limited exposure to the pain that communicating
modifiers everywhere has generated. As a result, I would have (perhaps
naively) tried to design a new mechanism. Using modifiers as a transport
mechanism is clearly a hack, but it may be a clever one. It seems worth
experimenting with it at least.
After reading the whole thread, I however wonder if this will be
backward compatible. If two devices expose a constraint that ends up
being encoded in the same binary form in a modifier (let's say for
instance the same pitch alignment), isn't there a risk that an
application not aware of this new scheme will pick that common modifier
when intersecting the modifiers list as done today, without realizing
it's not a real modifier ?

Flipping that argument, the reason why we still have no solution is
because we've constantly accepted stop-gap measures. Maybe it's time to
stop. It may feel a bit unfair to Marek that everybody until know got
away with hacks, but I don't think he would be left alone designing a
proper solution.

t
that to be the majority case, but I can't rule it out either. There's
also the issue that, even if the devices support configurable pitches,
the drivers may not implement it. That's fixable, but hardcoding the
pitch to 256 bytes without fixing that would be a regression.

Make that two. Thanks for the notice.

rantee on the order in which
buffers will be used. I'm aware this wouldn't be compatible with
explicit synchronization, and that's my point: camera hardware may not
always support explicit synchronization. As long as we can fall back to
not using fences then we should be fine.
