IMHO,
What is an abonination, is that cpusets are equired for this type of
isolation to begin with, even on a 2 processor machine.
I would like the option to stay and be extended like Max originally
proposed. If cpusets/hotplug are configured isolation would be obtained
using them. If not then isolcpus could be used to get the same isolation.
From a user land point of view, I just want an easy way to fully
isolate a particular cpu. Even a new syscall or extension to
sched_setaffinity would make me happy. Cpusets and hotplug don't.
Again this is just MHO.
Regards
Mark
