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
