Yes, it will need further userspace support to configure the pipeline, and to provide 3A algorithms for white balance, focus, and exposure times to the sensor. We are developing a stack called libcamera [0] to support this, but it's still in active development and not yet ready for use. Fortunately however, IPU3 is one of our primary initial targets.

It might help if we can get hold of a Dell 7275 sometime although I think Mauro at least has one ? If this is a priority for Canonical, please contact us directly. > Kai-Heng -- Regards Kieran
