High interrupt latency
Web> Where can I find this latency measurement for the ARMv8 Cortex-A53? I'm not aware that such a measurement exists for the Cortex-A cores; the best case will never happen for any real software so it's not really something which really worth measuring, and as per my first answer the realistic and worst case is totally dependent on the memory system … Web5 de jan. de 2024 · The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle …
