My name is Duane Kaufman, and I have an HP Spectre x360 16" with (I believe) an ov80x40 sensor.

My C/Linux skills are probably not up to the task of making my camera work, but I am willing to try (certainly willing to test!)

My particular situation may be hampered by the fact that this laptop has an electro-mechanical shutter, which shows up as "wmi PNP0C14:04 00000080 00000000" using acpi_listen, and is toggled by the F2 key (which works under linux, I can see/hear the shutter open and close).

I filed a bug with libcamera ([Bug 237] IPU6 Camera with ov08x40 (OVTI08F4 sensor) HP Spectre 16" Meteor Lake doesn't work), and Laurent Pinchart there suggested I send a report to linux-media@vger.kernel.org (which I did)

Please let me know what testing or whatnot I can do.

Hi Duane

I'm glad to see the sensor being used on a product that I hadn't heard of before.
I don't have enough hardware design details, so it may not solve your problem immediately, but I can take a look at it.

From your log, It appears that the OV08X is used for RGB sensor.
Could you share the kernel message with sudo dmesg?

Thanks

@DuaneKaufman, thank you for providing the information. It’d be great if you could edit your comment, and mark up the text using Markdown, and for logs longer than 10 or 20 lines to attach them as files please.

Sorry, I responded via E-mail, and apparently Markdown and attaching files are not supported.
My response is re-formulated below.

Dear Sir,

Thanks for the log, Duane.

However, the dmesg output only includes data from 10 sec after boot.
I need the log starting from when the OS loads ( 0 ~8 sec)
Can you provide the kernel log again?

Thanks
