PMP and Physical Memory Protection Domains: Pitfalls and Red Flags

Pitfalls and Red Flags for PMP and Physical Memory Protection Domains.

Pitfalls and red flags

Pitfalls and Red Flags for PMP and Physical Memory Protection Domains is anchored on Unauthorized-access block rate, PMP rule evaluation latency, and coverage of privilege-domain isolation tests.. Convert observations into mechanism-backed decisions with explicit ownership.

  • Tuning knobs without proving first failing mechanism.

  • Ignoring privilege, trap, and memory-protection side effects.

  • Mixing extension profiles across benchmark runs.

  • Shipping on one benchmark uplift without stress replay.
