Priority 3 - Debug, Trace & Instrumentation Hardware / 3.3 Trace IP (on-chip) & host trace sinks

As a firmware debugger, I want vemu to finish its ETM / PTM (instruction trace) model, so that I can depend on non-intrusive profiling for production firmware, not just the common path.

Why it matters

Non-intrusive profiling

Summary

HW instruction trace

Scope of work

Currently a register-only stub. Replace it with a working model of ETM / PTM (instruction trace) that actually exhibits the hardware behavior. What it is: HW instruction trace. Why it matters: Non-intrusive profiling.

Current state

Status: Stub only (registers, no behavior). Notes / evidence: ROM-table entry only.

Fund these first - this work can't be completed until they ship.
