Subject: [PATCH v2 0/2] perf/x86: various RAPL improvements and fixes
Date: Wed,  8 Jan 2014 11:15:51 +0100
Message-Id: <1389176153-3128-1-git-send-email-eranian@google.com>
Sender: linux-kernel-owner@vger.kernel.org

This short patch series provides the following improvements
to the RAPL support for perf_events:
 - support for RAPL PP1 energy counter
 - fix struct perf_event active_list field initialization

The PP1 counter maps to the builtin graphic card for client
processors. that is why it is called energy-gpu.

The new energy event is:
 - name: power/energy-gpu/
 - code: 0x4
 - unit: Joules
 - scaling factor: 2^-32 Joules.

In v2, we renamed energy-pp1 to energy-gpu. We dropped the Haswell
Celeron patch because it is committed already. But we add a fix for
the broken initialization of the active_entry list.
