Crate sbi_spec

Expand description

RISC-V SBI Specification structure and constant definitions.

This crate adapts to RISC-V SBI Specification version 2.0 ratified. It provides structures in Rust semantics and best practices to simplify designs of RISC-V SBI ecosystem, both implementation and applications.

You may find it convenient to use this library in a vast range of packages, from operating system kernels, hypervisors, to SBI bare metal implementations. This crate is no_std compatible and does not need dynamic memory allocation, which makes it suitable for embedded development.

Although this library is dedicated to RISC-V architecture, it does not limit which build target the dependents should compile into. For example, when developing a RISC-V emulator on platforms other than RISC-V, the emulator designed on other platforms can still make use of sbi-spec structures, to provide the necessary features where the emulated RISC-V environment would make use of.
