Hi all,
Does (any flavour of) plan9 / inferno make use of several cores on
(any flavour of) ARM?
We are investigating how a program can create interference (e.g. slow
down) with one running on different a different core in the context of
embedded, real-time systems. It turns out that most real-time OSes have
poor support of multicore, but the plan9 state of affairs is not clear
to us.
I guess plan9 on x86 do support multicore, but is it the case on ARM? In
particular, on the raspberry-pi 3?
Thanks, and if possible keep Dan (CC'ed) in the loop.
Hugues

yep. 9front zynq kernel runs fine with the two cores, all caches enabled.
