Module framebuffer_device 

Framebuffer Character Device Module

This module provides character device interface for framebuffer access. It integrates with the GraphicsManager to provide user-space access to framebuffer resources through the standard character device interface.

Overview

The FramebufferCharDevice provides:

• Basic read/write operations to framebuffer memory
• Control operations (ioctl-equivalent) for device configuration
• Integration with GraphicsManager for resource management
• Standard character device interface for user programs
• Support for Linux-compatible framebuffer ioctls
