Module manager

Device Manager Module

This module provides functionality for managing hardware devices in the kernel.

Overview

The device manager is responsible for:

• Registering and managing serial devices
• Tracking available device drivers
• Device discovery and initialization
• Managing device information

Key Components

• BasicDeviceManager: Manages fundamental I/O devices like serial ports
• DeviceManager: The main device management system that handles all devices and drivers

Device Discovery

Devices are discovered through the Flattened Device Tree (FDT). The manager:

1. Parses the device tree
2. Matches compatible devices with registered drivers
3. Probes devices with appropriate drivers

Usage

The device manager is implemented as a global singleton that can be accessed via:

• DeviceManager::get_manager() - Immutable access
• DeviceManager::get_mut_manager() - Mutable access

Example: Registering a serial device

use crate::device::manager::register_serial;
 
// Create a new serial device
let my_serial = Box::new(MySerialImplementation::new());
 
// Register with the device manager
register_serial(my_serial);
