Breenix GDB Debugging

When to Use This Skill

Use this skill when you need to debug the Breenix kernel at the assembly or C-level using GDB. Common scenarios:

• Investigating CPU exceptions, page faults, or triple faults
• Examining register state during interrupt handling
• Stepping through boot sequence or early initialization
• Analyzing syscall entry/exit paths
• Debugging context switches and process state transitions
• Inspecting memory layout and page tables
• Understanding TSC/APIC timer behavior

Quick Start

1. Launch QEMU in GDB Mode
