Arm Power State Coordination Interface (PSCI) library

This crate aims to offer functions and user-friendly types for parsing and constructing arguments of Arm Power State Coordination Interface (PSCI) calls. This functionality can be beneficial for both firmware and OS components.

However, doing the actual SMC/HVC/ERET calls, or implementing power management logic is beyond the scope of this crate.

Implemented features

  • Handling all PSCI 1.3 mandatory and optional functions
  • Handling both 32-bit and 64-bit call formats
  • Dedicated types for common PSCI call arguments
  • Unit tests

Limitations

  • The implementation does not handle pre-1.0 format suspend power state (see 5.4.2.1 Original format)

License

The project is MIT and Apache-2.0 dual licensed, see LICENSE-APACHE and LICENSE-MIT.
