Annotated Snippet

What:		/sys/class/pps-gen/
Date:		February 2025
KernelVersion:  6.13
Contact:	Rodolfo Giometti <giometti@enneenne.com>
Description:
		The /sys/class/pps-gen/ directory contains files and
		directories that provide a unified interface to the PPS
		generators.

What:		/sys/class/pps-gen/pps-genX/
Date:		February 2025
KernelVersion:  6.13
Contact:	Rodolfo Giometti <giometti@enneenne.com>
Description:
		The /sys/class/pps-gen/pps-genX/ directory is related to X-th
		PPS generator in the system. Each directory contain files to
		manage and control its PPS generator.

What:		/sys/class/pps-gen/pps-genX/enable
Date:		February 2025
KernelVersion:  6.13
Contact:	Rodolfo Giometti <giometti@enneenne.com>
Description:
		This write-only file enables or disables generation of the
		PPS signal.

What:		/sys/class/pps-gen/pps-genX/system
Date:		February 2025
KernelVersion:  6.13
Contact:	Rodolfo Giometti <giometti@enneenne.com>
Description:
		This read-only file returns "1" if the generator takes the
		timing from the system clock, while it returns "0" if not
		(i.e. from a peripheral device clock).

What:		/sys/class/pps-gen/pps-genX/time
Date:		February 2025
KernelVersion:  6.13
Contact:	Rodolfo Giometti <giometti@enneenne.com>
Description:
		This read-only file contains the current time stored into the
		generator clock as two integers representing the current time
		seconds and nanoseconds.

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.
