[PATCH 0/3] perf/x86/rapl: Enable RAPL for AMD Fam17h

[Stephane Eranian <eranian@google.com>]

This patch series adds support for AMD Fam17h RAPL counters. As per
AMD PPR, Fam17h support Package RAPL counters to monitor power usage.
The RAPL counter operates as with Intel RAPL. As such, it is beneficial
to share the code.

The series first moves the rapl.c file to common perf_events x86 and then
adds the support.
From the user's point of view, the interface is identical with
/sys/devices/power. The energy-pkg event is the only one supported.

$ perf stat -a --per-socket -I 1000 -e power/energy-pkg/
