AI-generatedSpurious wake‑up latency observed with AArch64 WFE timeout when event and timeout coincide
Symptom When using the AArch64 Wait For Event with Timeout (WFxT) feature (FEAT_WFxT), the core may wake either due to an external event or after the programmed timeout expires. If both conditions become true at the same cycle, the architecture leaves the priority decision to the implementation, which can lead to inconsistent latency across different cores.
