Surface Book 2 camera's are missing calibration files #1813
Description
I'm on Arch linux. I am able to open the camera feeds with cheese but the camera quality is really bad (inaccurate colors, flipped image, vignetting, etc.).
When running cam --list I get the following information:
[1:50:40.383889495] [21966] WARN IPAProxy ipa_proxy.cpp:177 Configuration file 'ov8865.yaml' not found for IPA module 'ipu3', falling back to 'uncalibrated.yaml'

Where do I get these calibration files?

Same issue on my surfacebook 2. I tried using chatgpt to create the files but whatever chatgpt suggested had no effect on camera quality. Do the other surface models have these calibration files? Can they be retrieved in windows? I tried a vm with a windows host (archlinux vm) and I suppose since the devices are virtualized, the cameras in a linux vm using the linux-surface kernel were perfect. Just not on bare metal.
