Hi, Andy!
I would like to understand how to use subdevice (like adp1653) in
current v4l2 framework from user space.
My understanding is following.
Kernel has two drivers (simplified view):

Hi Laurent,
If I understood your discussion with Russell [1] correctly, user pointer
buffers are required to be page-aligned because of the IOMMU API, and
it's desirable to keep the IOMMU driver that way for other subsystems
which may use it. So we're stuck with user buffers needing to be

Between two or more kernel drivers, a resource locking mechanism like the one
you've proposed works fine, but, when the driver is on userspace, there's one
additional issue that needs to be addressed: What happens if, for example,
