RustSBI is a RISC-V Supervisor Binary Interface (SBI) implementation library written in Rust, running in M-mode or HS-mode on bare-metal RISC-V hardware. It serves as firmware runtime for operating systems, hypervisors, and emulators, with binary images available via the RustSBI Prototyper.

Use cases

• boot a RISC-V operating system kernel with SBI firmware
• build custom firmware for a RISC-V SoC or board
• develop a hypervisor or emulator that needs an SBI implementation
• run embedded Rust on bare-metal RISC-V hardware
• implement RISC-V SBI specification v2.0 in a firmware project

When to choose

• you need a minimal, Rust-based SBI implementation for RISC-V M-mode or HS-mode
• you are building OS kernels, hypervisors, or emulators for RISC-V
• you want firmware that integrates with the Rust embedded ecosystem

When to avoid

• you need firmware for non-RISC-V architectures like ARM or x86
• you want a full-featured bootloader like U-Boot rather than a minimal SBI runtime
• your project requires no-Rust toolchains only
