Annotated Snippet

What:		/sys/bus/coresight/devices/dummy_source<N>/enable_source
Date:		Dec 2024
KernelVersion:	6.14
Contact:	Mao Jinlong <jinlong.mao@oss.qualcomm.com>
Description:	(RW) Enable/disable tracing of dummy source. A sink should be activated
		before enabling the source. The path of coresight components linking
		the source to the sink is configured and managed automatically by the
		coresight framework.

Annotation

Atlas domain: Support Tooling And Documentation / Documentation.
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.
