Feature Overview

This page provides an overview of the current TF-A Tests feature set. The Change Log & Release Notes document provides details of changes made since the last release.

Current Features

The following TF-A features are currently tested to some extent (this list is not exhaustive):

SMC Calling Convention
Power State Coordination Interface (PSCI)
Software Delegated Exception Interface (SDEI)
Performance Measurement Framework (PMF)
Communication and interaction with the Test Secure Payload (TSP)
Firmware update (or recovery mode)
EL3 payload boot flow
Secure partition support
True Random Number Generator Firmware Interface (TRNG_FW)

These tests are not a compliance test suite for the Arm interface standards used in TF-A (such as PSCI).

They do not cover 100% of the TF-A code. The fact that all tests pass does not mean that TF-A is free of bugs.

They are not reference code. They should not be considered as the official way to test hardware/firmware features. Instead, they are provided as example code to experiment with and improve on.
