AI-generatedDC CVAC's Point of Coherency Scope in ARMv8.2: Stale Cache Uncertainty
Goal Determine whether the DC CVAC instruction alone guarantees visibility of data written on one core to all other cores on ARMv8.2 systems, given the implementation‑defined shareability of its point of coherency (PoC). Constraints & Uncertainty The ARMv8‑A manual specifies that PoC may be either inner‑shareable or outer‑shareable, with no architectural
