Would it make sense to resort to polling at those
speeds instead? Maybe
poll using a constant reoccuring hrtimer?
Granted polling does not have the interrupt overhead. But I wonder how
it keeps up with respect to scheduling. Might one miss activity when
the kernel thread is not running?
Depends on how bad your jitter is, but I would hope that you'll get
better granularity than 23khz ;).
Worst case you can always try and isolate one CPU to do nothing but
poll. You have 4 of them after all :). But that gets quite complicated ...
