Introduce powercap userspace frontend

cpupower powercap-info
cpupower monitor -m RAPL

further development could provide:
cpupower powercap-set
to enable/disable RAPL domains, etc.

Hi, Thomas,

I want to give the patches a try but it seems that the patch format is corrupted, and I can not find them in patchwork neither.

thanks,
rui

Hi Rui,

long time no write... ;)
Thanks a lot for having look.

I am currently moving, the usual time problem, sigh.
I will test the way I sent patches first and come up with another version. But probably not before Mo.
The patches have been in SUSE cpupower package for some time. I finally find the time to post them, will do again asap.

Thomas
