Annotated Snippet

What:		/sys/firmware/efi/vars
Date:		April 2004, removed March 2023
Description:
		This directory exposed interfaces for interacting with
		EFI variables.  For more information on EFI variables,
		see 'Variable Services' in the UEFI specification
		(section 7.2 in specification version 2.3 Errata D).

		The 'efivars' sysfs interface was removed in March of 2023,
		after being considered deprecated no later than September
		of 2020. Its functionality has been replaced by the
		'efivarfs' filesystem.

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.
