# 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](https://developer.arm.com/documentation/den0022/latest/)
(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`.
