** Description changed: Config options below are useful for Realtime users: 1. CONFIG_WQ_POWER_EFFICIENT_DEFAULT disabled: energy saving is not that important for Realtime workload but locality of any workqueues (thus - waking up only local CPU). + cache locality and maybe lower latencies) is. 2. CONFIG_TIMERLAT_TRACER and CONFIG_OSNOISE_TRACER enabled: for debugging latency issues. 3. CONFIG_BLK_CGROUP_IOLATENCY enabled: for users wanting to have guarantees on IO latencies. 4. CONFIG_IRQ_TIME_ACCOUNTING enabled: for fine granularity task IRQ accounting.
