pub fn custom_cache_yield_wake_affine(ctx: &Ctx<'_>) -> Result<AssertResult>Expand description
CacheYield workers testing wake-affine placement after voluntary preemption.
All workers run CacheYield (strided RMW then sched_yield). After yield, the scheduler must decide where to place the waking task. Two cgroups on LLC-aligned cpusets make cross-LLC migration observable. Checks wake latency CV (consistent placement) and throughput fairness.
