The Linux kernel configuration item CONFIG_RCU_NOCB_CPU_CB_BOOST
:
( CONFIG_RCU_NOCB_CPU && CONFIG_RCU_BOOST ) && ( CONFIG_PREEMPT_RT )
Use this option to invoke offloaded callbacks as SCHED_FIFO to avoid starvation by heavy SCHED_OTHER background load. Of course, running as SCHED_FIFO during callback floods will cause the rcuo[ps] kthreads to monopolize the CPU for hundreds of milliseconds or more. Therefore, when enabling this option, it is your responsibility to ensure that latency-sensitive tasks either run with higher priority or run on some other CPU.
Say Y here if you want to set RT priority for offloading kthreads. Say N here if you are building a !PREEMPT_RT kernel and are unsure.
