interrupt-trace

Interrupt tracing captures and analyzes QEMU interrupt sequences to understand privilege transitions, register states, and trap behavior. Export your trace path, run QEMU with the provided flags, then parse the log to generate a summary of interrupt activity and privilege level changes.

Privilege level (CPL) transition analysis tracks mode changes during interrupts and exceptions, showing when the kernel enters privileged execution, which registers are affected, and how exception handling sequences execute across privilege boundaries.

Yes. Interrupt tracing captures register states and privilege transitions around traps and exceptions, letting you trace the exact sequence of events, verify handler execution order, and identify where unexpected mode or register changes occur.

This Skill uses low-overhead traces designed to minimize performance impact while capturing interrupt sequencing and state transitions, making it suitable for analyzing interrupt behavior in production-like QEMU environments without excessive slowdown.

Phase-based capture breaks interrupt tracing into stages, parsing QEMU logs to extract interrupt events, privilege transitions, and register snapshots at each phase, then generating structured summaries of the complete interrupt sequence.
