Rusted Firmware-A

This project provides an experimental Rust port of Trusted Firmware-A’s (TF-A) EL3 runtime firmware (BL31) for Armv9-A.

TF-A's boot images (BL1 and BL2) are out of scope of this project.

Responsibilities

The EL3 runtime firmware is responsible for:

  • Boot process coordination - Initiating the boot process of the components in the secure and normal worlds
  • Security state coordination - Managing transitions between normal and secure worlds
  • Secure Monitor Call (SMC) handling - Processing SMCs invoked by other software components

Supported SMC Interfaces

The current implementation supports:

For more details on each of these services, please refer to the SMC services overview document.

Supported Platforms

The following platforms are supported currently:

  • Arm Fixed Virtual Platform (FVP)
  • QEMU

Hardware and Software Requirements

RF-A is targeted at recent Arm devices and as such it makes some assumptions about the hardware it runs on and the software interfaces it implements or relies on. These assumptions are outlined here.

Getting started

See our Getting Started Guide.

See the RF-A architecture overview for an overview of the code structure.
