CSR Programming Model, Privilege Visibility, and Timer Facilities: Pitfalls and Red Flags

Pitfalls and red flags

Pitfalls and Red Flags for CSR Programming Model, Privilege Visibility, and Timer Facilities is anchored on CSR read/write hazard rate, timer interrupt accuracy (ns error), and software context-switch overhead attributable to CSR traffic.. 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.
