Note that this means that your system must have at least two CPUs in order for CONFIG_NO_HZ_FULL=y to do anything for you. -Alternatively, the CONFIG_NO_HZ_FULL_ALL=y Kconfig parameter specifies -that all CPUs other than the boot CPU are adaptive-ticks CPUs. This -Kconfig parameter will be overridden by the "nohz_full=" boot parameter, -so that if both the CONFIG_NO_HZ_FULL_ALL=y Kconfig parameter and -the "nohz_full=1" boot parameter is specified, the boot parameter will -prevail so that only CPU 1 will be an adaptive-ticks CPU. - Finally, adaptive-ticks CPUs must have their RCU callbacks offloaded.
