Raspberry Pi PiSP Front End configuration format
================================================
The Raspberry Pi PiSP Front End image signal processor is configured by
userspace by providing a buffer of configuration parameters to the
`rp1-cfe-fe-config` output video device node using the
:c:type:`v4l2_meta_format` interface.
The `Raspberry Pi PiSP technical specification
<https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf>`_
provide detailed description of the Front End configuration and programming
model.

Raspberry Pi PiSP Front End statistics format
=============================================
The Raspberry Pi PiSP Front End image signal processor provides statistics data
by writing to a buffer provided via the `rp1-cfe-fe-stats` capture video device
node using the
:c:type:`v4l2_meta_format` interface.
The `Raspberry Pi PiSP technical specification
<https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf>`_
provide detailed description of the Front End configuration and programming
model.Annotation

- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
