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.
