Public bug reported:
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).
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.
