Rolling latency statistics in microseconds: sample count, min / max / mean, and how many samples blew a budget. Fixed size, no heap; a subsystem (the preempting queue, a DMA path, a forwarding rule) keeps one and reports it for real-time visibility. More...

Detailed Description

Rolling latency statistics in microseconds: sample count, min / max / mean, and how many samples blew a budget. Fixed size, no heap; a subsystem (the preempting queue, a DMA path, a forwarding rule) keeps one and reports it for real-time visibility.
