You need the other 50% of the kernel side - the generation of bayer
statistics in the IFE, as well as generation of parameters to feed back
into the OPE - which requires a user-space implementation too, so a lot
of work there too.
I'd also say when we have an ICP we should be using it via the HFI
protocol, thus burying all of the IPE/OPE BPS and CDM complexity in the
firmware.
Understood Agatti has no ICP so you're limited to direct OPE/IFE
register access here. For HFI capable platforms - the majority - HFI is
the way to go.
I'll publish an RFC for Hamoa for that soonish so we can make sure both
coexist.
