gt; modifiers and replace them with something that works.
I think Daniel's forward compatibility plan is more solid than trying to
deprecate LINEAR itself, that seems like too much an uphill battle to me.

rucial part, because adding modifiers without
an actual use-case that they fix is just asking for more future trouble I
think.

quirements are generally implied. Mostly by stuff like tile size, but
there's others where the hw requirement flat out is that the buffer must
have a power-of-two stride (and maybe we should document these when they
pop up, but the only one I know of are the legacy i915 modifiers, which
are

ottom (yeah some hw overscans and gets
pissed if there's not memory there). So I think it's best to go overboard
here with verbosity.
There's also really funny stuff like power-of-two alignment and things
like that, but I guess we'll get there if that's ever needed. That's also
why I think we don't need to add all possible linear modifiers from the
start, unless there's maybe too much confusion with stuff like "exactly
64b aligned pitch" and "at least 64b aligned pitch, but you can add lots
of padding if you feel like".
