Hi,

I’d like to know about the v4l2 timestamp in Jetpack6.0.
In Jetpack5.0, v4l2 timestamp seems to be set like this in vi5_fops.c.

	vb->vb2_buf.timestamp = descr->status.sof_timestamp;

However, vi code architecture seems to be totally different in Jetpack6.0
and I couldn’t find the similar code block.

Does anyone know where the v4l2 timestamp is set?

It’s the same with JP5.

Thanks

Thank you for your comment.

I’m looking at kernel_src.tbz2 and its sha1sum is below.
e1aea96ae9d33ed2b14e20edefe7d5dd6f74bdf0 /dvs/git/dirty/git-master_linux/out/out_src/kernel_src.tbz2

I couldn’t find vi5_fops.c and other source files.
Am I looking at wrong place?
