I'm adding hot-plug support for the above arch and ran into performance issue
with execution of
partition_sched_domains () - About 0.5 sec per cpu, which is unacceptable with
the arch supported 4k cpus.
To my limited understanding, on the plat-eznps arch, where each cpu is always
running a single threaded process in
isolation mode, the above call is not necessary,
Can you please confirm (or reject) my understanding? If I'm wrong short
explanation will be appreciated.
If I'm correct, I will be grateful if you can point me to how to skip this call
in a way acceptable by community.
