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?
I also remember some talk about FIQ interrupts being faster than normal ones, but I never used them.
Same here. I would really like to try them!
