OVTI08F4:00 sensor not in media graph

OVTI08F4:00 sensor not in media graph

[Juliusz Chroboczek]

Hello,

This has been reported at

    <https://gitlab.freedesktop.org/camera/libcamera/-/issues/318>

A kind gentleman there recommended that I contact linux-media.  Since I am
not subscribed, please CC me with any followups.

Dell Pro Max 14 Premium MA14250 laptop (Arrow Lake CPU), Debian testing,
kernel 6.18.9+deb14-amd64, libcamera 0.7.0-2.

The camera appears to be recognised by the kernel:

    $ sudo dmesg | grep -i ipu
    [    0.004960] ACPI: SSDT 0x0000000051FDB000 0000F9 (v02 INTEL  IpuSsdt  00001000 INTL 20210930)

    [    6.822568] intel-ipu6 0000:00:05.0: IPU6-v4[7d19] hardware version 6

However, libcamera complains that it cannot find a sensor:

     $ cam -l
     [1:56:27.699418955] [20417]  INFO Camera camera_manager.cpp:340 libcamera v0.7.0
     [1:56:27.724735682] [20420]  INFO SimplePipeline simple.cpp:1899 No sensor found for /dev/media0
     Available cameras:

Running "media-ctl -d /dev/media0 -p" indicates that the sensor is not in
the media graph:

Please let me know if any further information would be useful.

Thanks for your help,

This laptop should start working with the CVS driver makes it to upstream.
I'd hope this happens for Linux v7.1, there are no guarantees though. The
ov08x40 and USBIO drivers already exist in the upstream kernel.

Cc Antti, too.

In the meantime you can try the CVS driver from here
