xdv-runtime

User Space Runtime for XDV OS.

Overview

The XDV Runtime provides the user space environment for XDV OS, wrapping dustlib and dustlib_k to provide:

• I/O operations
• Memory management
• String utilities
• Process management
• Task scheduling
• File system interface
• Console I/O
• Init process (PID 1)

Architecture

This runtime targets K-Domain operation on classical x86-64 hardware. Q and Phi domain requests are hardware-gated and return ERR_DOMAIN_NOT_AVAILABLE (100) when unavailable.
