Rusted Firmware-A

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

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
