Same here on SP6, EndeavourOS. Command "cam --list" shows the next:

I think a similar issue here:

Hardware model: Surface Pro 4
Kernel Version: 6.7.2-surface-1
Distribution: Ubuntu 22.04 with libcamera compiled to instructions provided here, I tried the latest version of libcamera as well as version 0.0.4 (based on this comment)
Secure Boot disabled

cam --list yields no errors, but also does not list available cameras.

dmesg | grep ipu3 yields the following (it fails in doing some things, error -22)

Similar to the cases above, e.g. dmesg | grep ov5693 yields this

Hi,

the issue was caused by introducing a pad flag check into the linux kernel starting from v6.7-rc1. Some fix is also available at the kernel mailing list, I have no idea why it was not implemented into the kernel and how to trigger some progress there. Any idea?

Downgraded to linux-image-6.6.11-surface-1 and camera is working again.

Best regards, Rene

See also #1359 (comment) for a workaround.

Since the patch linked above has been included in the lastest releases, could anyone confirm that the cameras do indeed work and that we can close this issue?

[tkaefer]

On my SP 6 with Ubuntu 23.10 and the 6.7.9 kernel the Cameras work - somewhat the back camera is just turned upside down (tested with qcam and cheese).

[qzed]

@tkaefer Thanks! I'll close this then.
