RSVC-OS — The Rust-Based Autonomous Kernel

RSVC-OS is Revolution Silicon's open-source, Rust-based real-time operating system and kernel purpose-built for the D1 SoC. Written entirely in safe Rust, it eliminates whole classes of memory-safety vulnerabilities at the kernel level — critical for autonomous systems where a crash means a crash landing. The microkernel architecture enforces strict process isolation between flight control, AI inference, and sensor fusion tasks, with deterministic scheduling guarantees down to 50 µs.

#[rsvc_task(priority = CRITICAL, deadline_us = 50)]
async fn flight_controller(ctx: FlightCtx) -> ! {
    let mut imu = ctx.imu.lock().await;
    let mut motors = ctx.motors.lock().await;

    loop {
        // Read IMU — guaranteed within 50 µs
        let attitude = imu.read_attitude().await;

        // PID control loop — no heap allocation
        let correction = pid_step(&attitude, &ctx.setpoint);

        // Write motor commands atomically
        motors.set_all(correction).await;

        // Yield to scheduler — next deadline in 50 µs
        rsvc_os::yield_task().await;
    }
