axdevice_base

Basic device abstraction library for AxVisor virtual device subsystem, designed for no_std environments.

Overview

axdevice_base provides core traits, structures, and type definitions for virtual device development, including:

• BaseDeviceOps trait: Common interface that all virtual devices must implement.
• EmulatedDeviceConfig: Device initialization and configuration structure.
• Device type enumeration EmuDeviceType (provided by axvmconfig crate).
• Trait aliases for various device types (MMIO, port, system register, etc.).

Usage Example

use axdevice_base::{BaseDeviceOps, EmulatedDeviceConfig, EmuDeviceType};

// Implement a custom device
struct MyDevice { /* ... */ }

impl BaseDeviceOps<axaddrspace::GuestPhysAddrRange> for MyDevice {
    // Implement trait methods ...
}

let config = EmulatedDeviceConfig::default();
