I think v1 just refers to "the first next variant of this function",
similar to how for example Microsoft COM APIs start without a suffix,
then get 1, 2, 3 etc appended as new variants "of the same" trickle in.

Correct, I just got lazily inspired by downstream here.  There it
switches on SDE_MDP_VSYNC_SEL which is based on DPU >= 5.0.0 as
explained in the patch.

Maybe add _and_ in there?
