The chips I'm deling with can certainly support doing that but I'm not
sure there'd be enormous advantages - a lot of the interrupt handlers
will either be trivial (eg, RTC ticks or alarms) or be serialised by a
need to interact with the chip anyway.  I'd expect this to be generally
true, though ICBW.

So in your case it would be possible to run the various subdevice
thread_fn handlers from your main interrupt thread one after each
other ?

That's what they're all doing at present outside of genirq.

They just are racy against disable/enable/request/free I guess :)
