All of which reminds me of perhaps *the* most important reason to keep
core functionality like "IRQ distribution" *inside* the kernel:
It has to pass peer review on this mailing list.
that's a reason to keep it in the *source*, that's not the same as
..
Ack. :)
keeping it in ring0 pinning down memory all the time etc ;)
..
I belive it *must* remain pinned in memory to be effective,
because I also know it must run much more frequently than it
currently seems to run, in order to respond to quick changes
in IRQ load.
Eg. a heretofore idle device is suddenly now being used to copy
a DVD-sized file around. It *must* respond quickly to changes
in load like this, or system latencies will suffer badly.
Cheers
