Making power policy just work

Making power policy just work

Parent article: Making power policy just work

Andi Kleen notes that:
| Tunables are basically "we give up, let's push the problem to the user"
| which is not nice. I suspect a lot of users won't even know if their
| workloads are bursty or not. Or they might have workloads which are 
| both bursty and not bursty. 

Tunables are also something for external daemons to change: the famous
example is the IBM z/OS Workload Manager (WLM), which looks at 
application (actually workload) progress and a table of requirements 
and adjusts CPU, IO and memory tunables to speed to slow the workload.

So "user" means "user mode".
