| Trusted Firmware-A Tests |
| ======================== |
| |
| The Trusted Firmware-A Tests (TF-A-Tests) is a suite of baremetal tests to |
| exercise the `Trusted Firmware-A (TF-A)`_ features from the Normal World. It |
| enables strong TF-A functional testing without dependency on a Rich OS. It |
| mainly interacts with TF-A through its SMC interface. |
| |
| It provides a basis for TF-A developers to validate their own platform ports and |
| add their own test cases. |
| |
| 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 |
| |
| 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. |
