Detailed Description

performance monitor shared memory

assessments: tx/rx: sample latency latency: system latency from IRQ to event in nsec interval: the interval at which the event occurs duration: the duration of the event itself roundtrip: the round trip latency in samples (requires special measurement prio: IRQL/thread priority
