## What it is
BlueOS kernel is an operating system kernel written in Rust by Vivo, emphasizing security, lightweight design, and generality. It is POSIX-compatible, supports Rust's standard library, and targets ARM32/ARM64 and RISCV32/RISCV64 architectures including QEMU platforms.

## Use cases
- build an embedded OS kernel in Rust
- run Rust std programs on a microcontroller
- develop a POSIX-compatible RTOS for ARM or RISC-V
- experiment with kernel development using QEMU
- port a lightweight kernel to new hardware boards
- learn operating system internals through a Rust kernel

## When to choose
- you want a Rust-written, POSIX-compatible kernel for embedded or IoT devices
- you need ARM or RISC-V support with QEMU-based development
- you want to run Rust standard library code on bare metal

## When to avoid
- you need a production Linux replacement with broad hardware board support today
- you require x86 or other architectures beyond ARM/RISC-V
- you need a mature kernel with extensive vendor board support

## Facets
- artifact type: library
- maturity: active
- function: programming-language, embedded, file-system, networking, concurrency
- domain: operating-systems, embedded-systems, developer-tools
- platform: rust, embedded, cross-platform
- tags: os-kernel, posix, rust-std, arm, riscv, qemu, iot, linux
