pub fn device_util(
engine_util: &[(ParsedInstance, f64)],
high: i32,
low: u32,
) -> Option<EngineHeadline>Expand description
Device-headline utilization for one adapter: the busiest single engine after
per-engine pid-summing — deliberately Task-Manager-Performance-tab-comparable
(§3.4). None when no instance matched: GPU-less runner, first PDH sample, or an
unmatched LUID — all normal.
