Breenix QEMU Debugger

About

The Breenix QEMU Debug Session skill provides an integrated framework for low-level kernel debugging within QEMU. It streamlines the setup of complex debug flags, manages log redirection for boot sequences, and facilitates live system inspection via the QEMU monitor. By automating the configuration of environment variables and providing structured commands for interrupt tracing, MMU operations, and CPU state analysis, it allows developers to efficiently diagnose triple faults, memory corruption, and hardware interaction issues in early-stage operating system development.

Key Features

• Advanced logging for interrupts, page tables, and CPU resets
• Targeted CPU state and register dump configurations
• Live kernel inspection via TCP and Stdio monitor interfaces
• Automated capture of OVMF firmware and guest OS error logs
• Log analysis patterns for diagnosing common kernel failures
• 4 GitHub stars

Use Cases

• Investigating interrupt handling bugs and APIC timer configurations
• Debugging memory management issues and page table walks
• Analyzing boot sequence hangs and triple faults in UEFI environments
