Through /sbin/hotplug. Is that not acceptable? I'm sure there will be a DBUS event generated from it :) I've heard that the memory hotplug notifiers are working just fine through that interface. > I can imagine using for notification a new signal, that could be sent by > an administrator or system service (batch manager, perhaps) to tasks if > their allowed CPUs or Memory Nodes or other such had changed. I recall some initial proposals for when CPUs were offlined, to send the applications that were bound to those CPUs a specific signal, but I do not know if that got implemented or not. Anyone know? thanks, greg k-h ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
