Camera board • Warnings from vc4.cpp and sdn.cpp when using libcamera

$

When I run code to initialise the camera manager and get a vector of cameras, I see the following messages:

Code:

WARN: RPiSdn sdn.cpp:40 Using legacy SDN tuning - please consider moving SDN inside rpi.denoiseWARN: RPI vc4.cpp: 302 Mismatch between Unicam and CamHelper for embedded data usage!
This is running on a Pi 3B rev1.2 with an imx219 camera attached. OS is bookworm armhf, (kernel 2024-05-29).
config.txt has:

Code:

camera_auto_detect=1 arm_64bit=0
among other incantations

As they are warnings, I am currently ignoring them. I have seen the first message before, but not the second. Previously I was using an original camera module (Omnivision?)

Some digging tells me that the second one is because the camera provides additional (but not necessarily reliable!) data regarding things like exposure time, so I'm fine with that. The first one seems to imply that I could make changes to eliminate it, but said digging hasn't turned up anything useful. Should I just ignore it?
