Make sure CPU 1 is full dynticks (it must be in the "nohz_full=" boot parameter
cpu mask).
To run:
$ make
# ./run
Look at the resulting trace in trace.1
hrtimer events should report you the tick events (unless you haven't
CONFIG_HIGH_RES_TIMERS=y) and tick_stop events tell you what's going on with full dynticks
behaviour.
trace.1.example shows an example of a successful full dynticks behaviour. The
tick got mostly stopped during the execution of the user loop.
