DESCRIPTION:Real-time computing has a strict rule: correctness means produc
 ing the right output within a non-negotiable deadline. General-purpose OSe
 s with their unbounded delays can't make this promise\, which is why we re
 ly on systems like the PREEMPT_RT kernel. Before this work\, however\, cri
 tical questions were left to guesswork: "Have we tested long enough?" and 
 "How do we know an even worse latency won't happen in production?"\n\nThis
  talk presents a toolkit that methodically answers these questions by appl
 ying Extreme Value Theory (EVT). Just as the Central Limit Theorem describ
 es the behavior of averages\, EVT provides the powerful statistical founda
 tion for predicting extreme maximums. We'll show how this tool forecasts p
 erformance limits\, helps diagnose deep-seated system bugs\, and provides 
 immense business value by turning uncertainty into data-backed confidence\
 , enabling robust SLAs and de-risking system deployment.
