I assume you're talking about the scheduler clock frequency (HZ), which
remains 250 per default. Bear in mind that the scheduler clock is only
used for time-slicing between tasks with equal priority. This is quite
separate from PREEMPT_RT, which makes it possible to preempt *lower*
priority tasks (including interrupt handlers) with low latency.
