How different is this from sm8250 which is already enabled on iris driver ?
As far as I remember, SM8250 support in Iris did not reach
feature-parity yet. So in my opinion it is fine to add new platforms to
the Venus driver, that will later migrate to the Iris driver.
I would say, from decoder side all codecs are there now on Iris. H264 merged,
while h265 and VP9 dec are posted as RFC, there is one compliance failure which
is under debug to post them as regular patches.
If we are mainly looking for decode usecases, then we should be on Iris.
Preference would be to stay on Iris, otherwise we would have that extra ask to
port it later from venus to iris.
Right now venus represents 9/20 - 45% of the patches being churned for
sc8280xp.

This is a good debate to have, however my memory of what we collectively
agreed both in public and private was to continue to merge new silicon
<= HFI6XX into venus unless and until iris hit feature parity for HFI6XX
and to continue with venus at that point for < HFI6XX.
So merging sc8280xp - HFI6XX is consistent with our agreement, the right
thing to do for our users and a big win in terms of technical debt
reduction.
I will post an update to this series ASAP.
