Quoting a recent article from LWN [1]
PREEMPT_DYNAMIC, was added to the 5.12 kernel by Michal Hocko in
2021. It allows the preemption choice to be deferred until boot
time, where any of the modes except PREEMPT_RT can be selected by
the preempt= command-line parameter. PREEMPT_DYNAMIC allows
distributors to ship a single kernel while letting users pick the
preemption mode that works best for their workload.
So if you specificity need a real-time kernel this won't give it to
you.
