# RustSBI
RISC-V Supervisor Binary Interface ([SBI](https://github.com/riscv-non-isa/riscv-sbi-doc/)) library in Rust; runs on M-mode or HS mode.

## Binary downloads
Most users would get RustSBI binary download from the RustSBI Prototyping System. Check out the link
[here](https://github.com/rustsbi/standalone) to download binary package for your platform.
Boards, SoC vendors and research groups would provide dedicated RustSBI package for supported platforms.
There are packages exists on [awesome-rustsbi](https://github.com/rustsbi/awesome-rustsbi): it is a curated list of
awesome things related to RustSBI, which includes some implementation projects maintained by individuals or the community.
Users on commercial boards may visit implementation specific distribution links depending on the platforms they need,
or consult vendors if they provide discrete RustSBI package support.
## Minimum supported Rust version
To compile RustSBI library, you need at least stable Rust version of `rustc 1.65.0`.
## Build this project
RustSBI is usually used as a library or dependency. If you wish to, you may build RustSBI library itself using the
following command:
```bash
cargo build
```
The build should finish without any errors.
Building under native platform will allow development of hypervisors and emulators.
To cross-build for a RISC-V platform environment, you may install the target and build onto it instead:
```bash
# If you don't have the cross compile target installed, install it first
rustup target add riscv64imac-unknown-none-elf
# Build this project as library
cargo build --target riscv64imac-unknown-none-elf
```
The target platform of RISC-V platform firmware is usually a bare metal target.
Under normal circumstances these targets in Rust would start with `riscv??-` and end with `-none-elf`.
## Features
- Feature rich and extensible operating system runtime
- Empower support, compatibility for machines, hypervisors and emulators
- Support to and develop with RISC-V SBI specification v2.0 ratified
- Written in Rust, builds under stable Rust
- Capable to develop with other firmware ecosystem projects
- Adapted for operating system kernel models on your choice
## Frequently asked questions
1. How would I build a RustSBI implementation?
RustSBI have extensive documents on such purposes! No matter what you are building with it, you will find some
documents about RustSBI on bare-metal environments, hypervisors and emulators.
Check it out at [RustSBI document main page](https://docs.rs/rustsbi).
2. Can I use RustSBI on C based kernels?
Yes, you can! RustSBI strictly follows RISC-V SBI standard. All features are prepares for all programming languages,
as long as they support RISC-V SBI defined calling convention.
If your kernel language supports other SBI implementations, usually it will support RustSBI in the same way.
## Talks and documents
This project is originally a part of rCore Summer of Code 2020 activities, inspired
by [MeowSBI](https://github.com/meow-chip/MeowSBI) and other similar projects. Now it is capable of running
rCore-Tutorial and other OS kernels on wide supported RISC-V devices.
There are multiple talks related to RustSBI dated back to Aug 2020. These talks discuss from design and abstraction of
RustSBI modules, to actual production and research usage scenario related to RustSBI and RISC-V bootloaders. Public
slides and blog articles of these talks are available at [RustSBI/slides](https://github.com/rustsbi/slides) page.
## Notes on platform implementation
1. RustSBI should be used as a library. Under normal circumstances, RustSBI platform can be implemented
with embedded Rust's `embedded-hal` libraries.
2. Contributions are welcomed! We welcome to implement and test RustSBI for both FPGA cores and real cores.
Implementations for emulators are also welcomed. If you are ready, start your own binary project and use
RustSBI in it!
3. If there is a bug in RustSBI project itself, fire an issue or pull request to let us know!
