Annotated Snippet

What:		/sys/devices/.../power_resources_D0/
Date:		January 2013
Contact:	Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Description:
		The /sys/devices/.../power_resources_D0/ directory is only
		present for device objects representing ACPI device nodes that
		use ACPI power resources for power management.

		If present, it contains symbolic links to device directories
		representing ACPI power resources that need to be turned on for
		the given device node to be in ACPI power state D0.  The names
		of the links are the same as the names of the directories they
		point to.

Annotation

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.
