Implement userspace RAPL bits in cpupower

[Thomas Renninger <trenn@suse.de>]

Hi,

I'd like to ask whether there already exist userspace bits
for the powercap/rapl drivers?

Afaik there is some "read-only"/monitor code in turbostat,
but it is not intended to add any modifying code in there?

I would like to avoid yet another (Intel) CPU specific
userspace tool, like:
tools/power/x86/x86_energy_perf_policy
tools/power/x86/turbostat

and it would be great if userspace bits could be added to
cpupower utility
tools/power/cpupower

I searched for rapl and powercap in the MAINTAINERS list,
but there wasn't any match. Is there a candidate (Jacob?) who
might be the right one or who volunteers for this?

Thanks for any hints and any discussion input,

      Thomas
