$ ps -A|grep IRQ

Nope. ps -A|grep IRQ returns nothing. Apparently I did miss the config
option. I just looked through the .config file I used and I could find
no PREEMPT_RT option.
These are the PREEMPT related values I can find in my .config.
# CONFIG_SCHED_SMT is not set
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
CONFIG_PREEMPT_BKL=y
I've read several howtos on adding Ingo Molnar's RT patch. None that
I've read say anything about having to explicitly adding this option to
the config file. What did I miss?
