All, I don't know who to direct this to, so I added the names of individuals working on intel_ipu6 related patches. I'm running the 6.10.5-arch1-1 and 6.10.5-arch1-1-surface kernels on a Microsoft Surface Pro 8 in EndeavourOS. The Surface Pro 8 has the ov5693 (front) and ov13858 (rear) sensors. Only the front sensor is recognized by libcamera. In all of the camera applications that I used (cheese, kamoso, and qcam) the video is inverted (upside down). It was recommended on the Surface Linux Github page (https://github.com/linux-surface/linux-surface/discussions/1354#discussioncomment-10367513) that I report this issue here. Here are some outputs: $ v4l2-ctl -l -d $(media-ctl -d /dev/media0 -e 'ov5693 2-0036') User Controls exposure 0x00980911 (int) : min=1 max=1030 step=1 default=1030 value=1030 horizontal_flip
