+PREEMPT_RT
+PREEMPT_RRCU	Mandatory for RT
+RCU_BOOST	Boost RCU or RT task can starve completion of RCU GP
+RCU_BOOST_DELAY	Default value
+RT_GROUP_SCHED	Disabled as it complicates configuration for non-root users
+CMDLINE		skew_tick moderates jitter on largerr systems
+BCACHE		Disabled historically for stability reasons
+PREEMPT_TRACER	Disabled due to overhead, enabled on rt_debug
