===================================
TEE (Trusted Execution Environment)
===================================

This document describes the TEE subsystem in Linux.

Overview
========

A TEE is a trusted OS running in some secure environment, for example,
TrustZone on ARM CPUs, or a separate secure co-processor etc. A TEE driver
handles the details needed to communicate with the TEE.

This subsystem deals with:

- Registration of TEE drivers

- Managing shared memory between Linux and the TEE

- Providing a generic API to the TEE

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.
